34th Annual Congress of the European Association of Urology Barcelona, 15-19 March 2019

EAU19 honours innovators and notable contributions Congress officially commences in Barcelona By Jen Tidman and Erika de Groot The vocal prowess of “Carmen”, the name of the lead in the iconic opera by French composer Georges Bizet, echoed throughout the auditorium and kick-started the opening of the EAU19 Congress. At the Opening Ceremony, EAU Secretary General Prof. Christopher Chapple (GB) welcomed delegates who came from different parts of the world. Prof. Chapple also emphasised the need for well-trained urological nurses and the importance of the cooperation between the EAU and the European Association of Urology Nurses (EAUN). Distinguished recipients of this year’s Honorary Memberships were recognised at the ceremony: Prof. Dr. Yuri Alyaev (RU), Prof. Dr. Michael Droller (US), Prof. Hartwig Huland (DE), Prof. Michael Jewett (CA), and Prof. Dr. Jørgen Nordling (DK). Two of these renowned beneficiaries expressed their gratitude for their patients. Prof. Huland said, “My advice to those who want to pursue academic urology, learn from your patients. What we’ve learned from the patients

that we’ve treated will benefit the next generation of patients.” Prof. Jewett stated, “I would like to thank the patients that I’ve looked after for what they’ve taught me. I’m now pursuing the study of engaging patients and activating them in their care which, I believe if it were a drug would be a ‘blockbuster drug’ that will impact on overall survival of these cancer specialties.”

The Opening Ceremony also highlighted this year’s awardees: Prof. Freddie Hamdy (GB) was recipient of EAU’s top honour, the Willy Gregoir Medal. He said, “One of my passions is to develop academic careers. I discovered early that success follows seed and soil. There are amazing seeds in our training community but they will only succeed if they are embedded in fertile soil. It is therefore our responsibility to provide this environment to our department.”

Other notable awardees included current EAU Adjunct Secretary General – Science, Prof. Dr. Francesco Montorsi (IT), who accepted the EAU Frans Debruyne Lifetime Achievement Award; Dr. Maarten Albersen (BE) who won the EAU Crystal Matula Award; Dr. Giuseppe Simone (IT) who received the EAU Hans Marberger Award; and Prof. Peter Alken (DE), who was recipient of The Innovator in Urology Award. The EAU Ernest Desnos Prize was granted to medical company, KARL STORZ SE & Co. KG, for extraordinary contributions to the field of urological history. Dr. Sybill Storz (DE), daughter of company founder Mr. Karl Storz accepted the accolade. The last awardee of the evening, Dr. Veeru Kasivisvanathan (GB) shared “To all of you out there who dream of doing something, keep working at it because anything is possible.” Dr. Kasivisvanathan received the EAU Prostate Cancer Research Award. The final acts of “Carmen” marked a festive conclusion of the ceremony, which was followed by the EAU Networking Reception.

The 34th Annual EAU Congress officially started to the sound of Bizet’s Carmen

ESO Observatory features forecasts in PCa management A multidisciplinary take on what to expect in the coming year By Erika de Groot The “6th ESO Prostate Cancer Observatory: Innovations and care in the next 12 months” showcased predictions by experts from diverse fields in prostate cancer (PCa) treatment. Chaired by Prof. Dr. Jeroen Van Moorselaar (NL) and Mr. John Dowling (IE), the session was introduced with the lecture “The urologist’s perspective on focal therapy”. Prof. Dr. Roman Ganzer (DE) discussed ongoing trials with results to look forward to, such as the multicentre study “MRI/US Fusion Imaging and Biopsy in Combination with Nanoparticle Directed Focal Therapy for Ablation of Prostate Tissue”; the Partial prostate Ablation versus Radical prosTatectomy (PART) study; and the Robotic Surgery After Focal Therapy (RAFT) trial. In his presentation “The urologist’s perspective on surgery”, Prof. Markus Graefen (DE) made several

predictions: the role of radical prostatectomy (RP) as the first line treatment option in advanced PCa will increase; neoadjuvant androgen-deprivation therapy (ADT) might need reconsideration; cytoreductive RP will become routine; and salvage RP after failure of focal therapy will be further explored. According to Dr. Roderick Van Den Bergh (NL), active surveillance (AS) should be the standard option, reduction in the variation in the AS use is needed, and AS should be standard part of screening policies. In his lecture “The urologist’s perspective on active surveillance”, he stated, “We need to also focus on the timing of treatment, not only its avoidance. We need wider inclusion, targeted biopsy risk stratification, and a personalised approach.” Dr. Olivier Rouvière (FR) recommended magnetic resonance imaging (MRI) before any prostate biopsy. In his presentation “The imaging specialist’s perspective on MRI”, he predicted that risk stratification will be used to determine who should undergo a biopsy after MRI and that the role of systematic biopsy will gradually decrease. In addition, Dr. Rouvière forecast that obtaining a substantial number of targeted cores from each lesion will remain necessary due to the imprecision of the MR/US fusion methods, and that certification of radiologists and the use of quantitative MRI will improve the reproducibility of interpretations. In his lecture “The pathologist’s perspective”, Prof. Dr. Ferran Algaba (ES) shared his insights on accurate pathology wherein not all pattern 4, pT2a, pT3a, and positive margins are the same. He also recommended the inclusion of simple molecular pathology, as easy molecular markers can help some patients. Prof. Algaba added that in terms of reproducible pathology, the aim is to improve the pathology image base for standardisation.

Prof. Ganz discussing ongoing trials at the ESO PCa Observatory

According to Dr. Alberto Bossi (FR), genes are crucial in patient profiling. During his presentation “The radiation oncologist’s perspective” he said, “The [treatment] landscape is ready to use genetic profiling

for daily decision-making for patients undergoing radiotherapy.” In her lecture “The medical oncologist’s perspective”, Prof. Silke Gillessen Sommer (GB) shared her expectations for the next two years. Androgen receptor (AR)-antagonists will be a new option in addition to androgen-deprivation therapy (ADT) for metastatic castration-sensitive PCa. In non-metastatic castrationresistant prostate cancer (nmCRPC), treatment with AR-antagonists will be standard for the majority of patients with a short PSA doubling time (PSADT). For mCRPC, precision medicine will become a reality. However, the costs and availability of the abovementioned drugs will be an issue.

During his presentation, “The andrologist’s perspective”, Dr. Maarten Albersen (BE) anticipated more AS is for improvement of preservation of sexual function in 2019; and more hypofractionation without increased sexual side effects. He added that there would be an increased awareness of and lower threshold in offering therapy for sexual dysfunction. On behalf of Mr. André Deschamps (BE), Mr. Dowling discussed the three pillars in PSA screening in the lecture “The patient’s perspective”: patient awareness, PSA-led screening with risk stratifications and parameters, and treatment should be carried out in multidisciplinary centres.

Professors James N’Dow (GB), Yeong-Shiau (TW) and Li-Qun Zhou (CN) were delighted to chair the Joint Session of the EAU and the World Chinese Urologists, providing Chinese-speaking urologists with a stage to discuss a wide range of topics. Three oncological topics were highlighted: 1. advancing the diagnosis techniques for urological cancer in order to improve treatment outcomes, 2. Chinese urological cancer registries, and 3. the need for patient engagement in urological cancer care. In terms of cancer diagnosis, Dr. See Tong Pang (TW) noted that current conventional approaches all have limitations in detecting genitourinary cancers. In PCa, PSA is used as a screening tool, but causes several problems, e.g. false positive and false negative percentages, and in BCa, cytology is used as a screening tool, but lacks the sensitivity to detect cancer. The same poor sensitivity is seen in kidney cancer detection. The genomic background of cancer can play a more differentiating role taking into account a new diagnostic strategy based on nanotechnology with biomarkers. The development of a CMX biochip is a novel way of

increasing detection sensitivity up to 80%, which can reduce unnecessary biopsies and may lead to accurate, rapid, non-invasive and low-cost detection methods. A colleague of Dr. Ren Shancheng (CN) delivered his contribution on registries. There are nine consortiums in China covering a wide range of oncological publications and data. The shared database includes over 20,000 cases and contains clinical guidelines. China’s vastness provides a unique opportunity to study different kinds of

cancers and the final data will improve the care of Chinese patients. The need for patient engagement is important in developing guidelines, according to Ms Karin Plass (NL), EAU Guidelines Office Manager. Organisations such as the EMA, FDA, and NHS have set up full patient engagement programmes. Having patients as partners in healthcare may result in better patient outcomes and improved quality and safety. Patients want valid and trustworthy information from reliable sources such as EAU Patient Information and the EMA. In the field of andrology, two speakers got to the stage: Prof. Chen Yu (TW) on “Penile Augmentation: The role of urologists in Taiwan”, and Mr. Suks Sukhbinder Minhas (GB) on “Penile curvature surgery: European perspectives”.

Discussion at the EAU-World Chinese Urologists Joint Session covered topics including oncology and penile curvature

Prof. Chen Yu (TW) discussed rare cases where genetic and hormonal problems can cause a condition called micropenis; an erect penis of less than 7 cm. In Taiwan, penile augmentation is mostly performed by plastic surgeons who are well-trained in managing penile tissues using high-tech methods such as Da Vinci robotic Xi surgical systems.

One Spanish renaissance ‘proto-urologist’ is Andreas Vesalius (1514-1564), the so-called ‘prince of anatomy’ and personal doctor of Charles V and Philip II. Several Spanish anatomists were active in Paris at the time. A lesser-known contemporary of Vesalius was Andres Laguna (1499-1559), author of Anatomical Method (1535). This work describes horseshoe kidney and ileocecal valve. Juan Valverde de Amusco (c 1525-1587 published anatomical work in Rome in 1556. His illustrations (and even a portrait painting of him) are often confused with Vesalius. Valverde described the prostate as a “spherical mass of meat”.

Spanish innovators Prof. Javier Angulo Cuesta (ES) explored the life of renowned Cuban-born urologist Joaquín María Albarrán (1860-1912), particularly how he was influenced by Spain, and how in turn he impacted Spanish urology. Albarran was orphaned at an early age and taken to Spain for his studies. After becoming one of Europe’s foremost urologists, he influenced dozens of followers in the Spanish and French medical world. Dr. José Maria Gil-Vernet Sedo (ES) spoke on his grandfather Salvador’s work in the 1940s, particularly his publication of Patologia Urogenital (1944), a hugely influential and beautifully illustrated volume. The role of the medical illustrator (particularly with regard to Spanish urology) is further highlighted in Dr. Luis Farina’s chapter in De Historia Urologiae Europaeae Vol. 26, available for all EAU members at the Membership booth from Saturday morning.

Over a period of several decades in the 16th and 17th centuries, descriptions can be found in Spanish medical sources of prostatism, stone treatment, and particularly and uniquely, New World remedies. Spanish doctors and scientists studied chocolate, cacao and cantarida (“Spanish fly”) as aphrodisiacs. The New World also brought (urological) disease, and Spanish doctors pioneered the description and treatment of syphilis, which originated in Hispaniola and reached Europe through Barcelona(!) and Naples.

Spain has greatly contributed to the field of urology, through its scholars, surgeons and innovators, the audience learned at the EAU History Office’s Special Session on Friday afternoon. Particularly striking is the role that Spain’s former empire played in the development of Spanish urology: from previously unknown diseases and herbs that reached Spain from the New World to the LatinAmerican urologists who trained and worked in Spain, reaching great new heights. The tale of Spanish urology is inextricably linked with Spain’s history of overseas conquest.

Silay encouraged young academics to attend the speciality session “Leadership and the EAU” and the ESU course “Improving your communication and presentation skills” on Monday at EAU19, as well as the forthcoming YAU19 meeting in Vienna. This year is the second consecutive year that a YAU member has won the EAU Crystal Matula award, with Maarten Albersen (BE) scooping 2019’s prize after Silay’s success in 2018. He is also one of two recipients of an EAU Research Foundation (EAU-RF) seeding grant awarded to support original research by a junior investigator. During the YAU session Albersen presented on how he developed this successful research bid, in order to help other young academics applying for the next round. He highlighted the importance of demonstrating innovativeness and the potential for larger-scale

funding, as well as personal motivation and knowledge. Anders Bjartell (SE), Chairman of the EAU-RF, echoed this when commenting on the quality, feasibility and potential impact of two research proposals presented by YAU members Maria Carmen Mir Maresma (ES), Paolo Capogrosso (IT) and Paolo Verze (IT). “The most interesting thing for a reviewer is what is in the design, what is going to be done, and whether it is possible,” he said. “Look at the Guidelines, the need, and the real-world data.” The YAU awards were also presented during this session: Fabio Castiglione (GB) was named as reviewer of the year; Bernhard Haid (AT) accepted the award for the best paper published in 2018 by a YAU group; and Panagiotis Kallidonis (GR) accepted the award for best poster presented at EAU19 by a YAU group.

EAU-USANZ delivers updates in the region

Welcome to EAU19!

Reshaping the workforce, reassignment surgery updates By Erika de Groot

surgical procedures currently offered in the region.

Female-to-male (FTM) gender reassignment surgery and the practice patterns of female urologists in Australia and New Zealand were examined during the Joint Session of the European Association of Urology (EAU) and the Urological Society of Australia and New Zealand (USANZ). This Urology Beyond Europe session was chaired by Prof. Peter Heathcote (AU) and Prof. Manfred Wirth (DE).

In the first two years of practice, a total of 17 patients have undergone procedures: 13 RAP, 2 ALT, 1 PP and 1 Meta. However, not all patients went through all stages. Complications, functional outcomes, and measures on patient-reported outcome were assessed.

In her lecture, “Practice patterns of female urologists in Australia and New Zealand: Do we need to know?”, Dr. Lydia Johns Putra (AU) disclosed that more women in Australia and New Zealand are joining the urology workforce. She added that on average, they are younger than their male counterparts and are mainly general urologists.

A total of 54% patients had complete sensation of the phallus, and 46% had near completion. 60% reported penile implant use, with 100% adequate implant rigidity.

Female urologists do not take as much time off and intend to retire aged between 60 and 69. Dr. Putra also stated they are more likely to have children but fewer children per individual; work shorter hours; and are more likely to subspecialise compared to female urologists in the United States. FTM surgery “We have successfully established an expert service for gender reassignment surgery in Brisbane, Australia,” said Dr. Hans Goossen (AU) during his presentation “Female to male gender reassignment surgery Australia: Early experience and outcome”. Metoidioplasty (also known as Meta), Radial Artery Forearm Flap (RAP), Antero-Lateral Thigh Flap (ALT) and Pubic Phalliplasty (PP) are

Dr. Goossen stated that complication rates appear similar to the reported literature; no complete loss of phallus, no major complications of donor sites, and no cardiovascular events. Goossen added that overall patient satisfaction in terms of phallus cosmesis is high (54% rated excellent and 46% good) and that the majority of patients rated scrotum cosmesis as excellent (22%), good (67%) and average (11%). Patients also reported excellent and good urine flow (60% and 10% respectively). A total of 54% patients had complete sensation of the phallus, and 46% had near completion. 60% reported penile implant use, with 100% adequate implant rigidity. Patients’ gender dysphoria was resolved in 31%, with the other 69% reporting great improvement.

Post-biopsy infections: Better be prepared! Standards and recommendations for antibiotic prophylaxis in transrectal prostate biopsy Gernot Bonkat Chairman Guidelines Panel on Urogenital Infections CEO and Head Physician alta uro AG, Basel (CH)

A transrectal prostate biopsy is frequently performed to obtain tissue for the histological diagnosis of prostate cancer. The procedure is indicated by an abnormal digital rectal examination of the prostate, an elevated prostate specific antigen (PSA) or suspicious findings in multiparametric magnetic resonance imaging (mpMRI). This short review discusses the most promising antimicrobial strategies to reduce infectious complications in men undergoing prostate biopsy. It is estimated that more than 1 million men over 65 years have had a prostate biopsy as part of the Medicare programme in the United States in 2003, with an annual prevalence of about 1,600/100,000 men at risk1. The National Health Service (NHS) in Great Britain recorded 49,495 men as having had a prostate biopsy in 2015, giving a biopsy prevalence of 500/100,000 men at risk per year2. Post-biopsy infections Most prostate biopsies are transrectal ultrasound guided (transrectal ultrasound; TRUS)3. Thus, biopsy needles can be accurately placed in the prostate under local anaesthetic with ultrasound image guidance and a systematic sequence of tissue samples taken for examination4. Each biopsy core requires a separate entry and passage of the needle and generally a single needle is repeatedly used to obtain a set of biopsies from each individual. Needle placement into the prostate from the bowel bears a high risk of introducing micro-organisms in tissue layers, urinary system or blood stream. This may cause infectious complications, ranging from mild prostate inflammation to life-threatening urosepsis. However, the risk varies between cohorts and according to definitions of infection. While infectious complications were only rarely reported in the past, recent evidence indicates increasing rates of post-biopsy infections. A Canadian study reported an increase from 1% in 1996 to 4.1% in 2005 and a mortality in one men out of 1000 following prostate biopsy5. A recent well-controlled study found a 7% rate of microbiologically proven infection6. Two major strategies Two major strategies could reduce risk of infection after prostate biopsies: I) administration of antimicrobial drugs and II) technical modifications. The most frequently used strategy is administration of an antimicrobial prophylaxis. The rationale is that a sufficient concentration of an antimicrobial drug should be present in the prostate during biopsy. That way, survival of bacteria implanted by the biopsy needle is limited and clinical infection is inhibited. Another antimicrobial intervention is washing the rectal wall with antiseptics, such as povidone iodine, prior to biopsy to reduce bacterial contamination of the needle entry point. Antimicrobial prophylaxis Antimicrobial prophylaxis to reduce infectious complications was evaluated for the first time in a randomised study published in 19799. Many more studies followed and were comprehensively analysed in a Cochrane review in 20118. For all investigated parameters (bacteriuria, bacteraemia, urinary tract infection, fever, hospitalisation) the antimicrobial prophylaxis was superior compared to the control/ placebo groups (in all cases p < 0.05). In 2015, another updated systematic review and meta-analysis was published, including nine trials analysing antibiotics versus placebo/no treatment. The authors showed the clinical benefit of antimicrobial prophylaxis compared to control/no prophylaxis regarding the primary endpoints bacteriuria, bacteraemia, fever, UTI, and hospitalisation (in all cases p < 0.05)9. Interestingly, the rate of adverse events due to antimicrobial prophylaxis was not increased in the antimicrobial intervention group (p = 0.63)8. Thus, antibiotic prophylaxis is currently the gold standard worldwide3. Saturday, 16 March 2019

Duration of antimicrobial prophylaxis The duration of antimicrobial prophylaxis is a matter of debate. The currently available RCTs include single shots, one-day, three-day, five-day and seven-day regimes. The Cochrane analysis of 2011 compared a three-day regimen with a single shot/one-day prophylaxis. In all analysed endpoints no significant differences were detected (for all p > 0.05), only postoperative bacteriuria was reduced in the three-day intervention (p = 0.01)8. However, the Cochrane analysis from 2011 excluded studies with patients at risk for infective complications (e.g. indwelling catheters, diabetes etc.) and mixed up a single shot prophylaxis without full 24-hour duration of action and full one-day regimens. In an updated meta-analysis from 2015, again, no substantial differences between longcourse versus short-course treatments were detected regarding the clinical outcomes fever, urinary tract infection and hospitalisation (in all cases p > 0.05)9. To summarise, future metaanalyses will have to include studies with patients being at risk for infectious complications to represent the real clinical situation. Augmented antimicrobial prophylaxis A combination of multiple antibiotics was proposed to overcome increased infectious complications caused by antibiotic resistance. Most studies report infectious complications in a retrospective arm and compare the data with a prospective arm recorded after the introduction of a combination therapy. A metaanalysis published in 2,016 identified three RCTs with 659 patients and five case-control studies with 3,404 patients on this issue10. Similar to the Cochrane review of Zani et al.8 patients with heart disease, prosthesis, pre-biopsy bacteriuria and indwelling catheters were excluded. The authors evaluated bacteriuria, bacteraemia, fever, UTI, hospitalisation and drug-resistant bacteria isolated in urine and blood. All seven endpoints significantly favoured the augmented antimicrobial use (in all cases p < 0.05). The authors concluded that the addition of an antimicrobial agent to the basic antimicrobial prophylaxis can contribute to the reduction in severe infection and drug resistance. They point out that this might be beneficial for high risk patients, although they were excluded in these studies. In addition, it has to be considered that the casecontrol studies usually compare data from a retrospective cohort (with usually high infection rates) with a prospective arm recorded after the introduction of an intervention using a combination therapy. Thus, a significant bias is present. Four different antimicrobials The augmented prophylaxis can take bizarre dimensions: In the most recent study performed in Iran, the authors randomised 450 patient to a combination of four different antimicrobials (ceftriaxone plus amikacin plus ciprofloxacin plus metronidazole) or the standard prophylaxis being ciprofloxacin plus metronidazole11. The incidence of infectious complications in the intervention group was reported to be significantly lower than that in the control group (4.6% versus 0.9%, p = 0.017). However, the long-term complications regarding the development of antimicrobial resistance must be considered. Choice of antimicrobial class Several studies investigated the most suitable antibiotic for prophylaxis in men undergoing prostate biopsy. Due to their valuable pharmacokinetic properties in prostatic tissue, fluoroquinolones have been widely evaluated. However, in the analysis of available RCTs no antibiotic class was shown to be clearly superior. This was also shown in the Cochrane review by Zani et al.8. Specifically, the fluoroquinolones have been in discussion in recent years because of increasing fluoroquinolone resistance in the faecal flora.

International Urology and Nephrology, The authors further concluded that fluoroquinolone resistance drives the higher rates of infectious complications in the standard antimicrobial prophylaxis group16. Up to now, a total of three RCTs have been published involving 1,337 patients17-19. While in two studies infectious complications occurred only in the standard prophylaxis group18-19, the third study showed an equal distribution of infectious complications17. Of note, the later study demonstrated an unusually high rate of infectious complications with a sepsis rate of 5.2% among all groups. To give a final recommendation, a meta-analysis of the available RCTs is mandatory. Conclusion The available data only show that antimicrobial prophylaxis is of significant advantage to reduce infectious complications following prostate biopsy. The augmented and targeted antimicrobial prophylaxis shows some potential, but needs further validation. References 1. Loeb, S., et al., Complications after prostate biopsy: data from SEER-Medicare.

Currently, fosfomycin is in focus as a good alternative. However, from the three available RCTs only one RCT showed a significant reduction of infectious complications compared to standard prophylaxis with fluoroquinolones12-14. Nevertheless, a recent metaanalysis which included those three RCTs and two retrospective cohorts reported significantly lower infectious complications in the fosfomycin cohort compared to the fluoroquinolone based prophylaxis (RR = 0.20, 95% CI: 0.58 - 5.23, p = 0.00001)15.

Stem cell therapies in erectile dysfunction: Is it too early? Trials show that regenerative cell-based therapy for erectile dysfunction is probably safe Maarten Albersen, MD, PhD (FEBU) Dept. of Urology University Hospitals Leuven (BE) Dept. of development and regeneration KU Leuven (BE)

Erectile dysfunction (ED) is defined as the inability to attain and maintain erection of the penis sufficient to permit satisfactory sexual activity. This disease most commonly affects men from 40 years of age with a clear age-associated increase in prevalence. There is a large number of disorders known to contribute to the development of ED, including but not limited to diabetes, hypogonadism, metabolic syndrome, cardiovascular disease, cigarette smoking, pelvic neurovascular injury, and local disorders, such as Peyronie’s disease. The condition may have significant negative impact on quality of life of both the patients and their partners.

differentiated daughter cell. In ‘stochastic differentiation’ one father cell divides into two differentiated cells, while another father cell divides into two exact copies of itself in order to maintain the population of stem cells. Differentiation into more specialised cell types, e.g. smooth muscle cell, endothelial cell, or neuron was initially thought to serve as a replacement of defected or apoptotic cells in stem cell therapy (the “building block theory”). More recently, however, various types of stem cells have been shown to influence the environment into which they are transplanted in a paracrine fashion (the “paracrine theory”), and the principle of engraftment and differentiation has been questioned. Stem cell types reported in ED animal research mainly include adipose tissue-derived SCs (ADSCs), bone marrow-derived SCs (BMSCs), and muscle derived SCs (MDSCs), although there are rare reports on the use of embryonic stem cells. Theoretically, these cells can differentiate into all cell types of the mesodermal origin, including muscle, fat and bones, although extra-linear differentiation has been shown in-vitro3.

“Available treatment armamentarium solely provide symptom relief”

Iatrogenic trauma of the neurovascular bundle as result of radical prostatectomy (RP) is a frequent cause of ED. This complication remains frequent despite a refinement of nerve-sparing operative techniques including the introduction of robotassisted laparoscopy. Post-prostatectomy erectile dysfunction remains difficult to treat due to the lack of bio-available NO. Furthermore, as detailed above, Understanding the molecular aspects of ED PDE5i typically do not work well in this group of pathogenesis has successfully resulted in widespread patients5. The initial studies on stem cell application use of phosphodiesterase type 5 inhibitors (PDE5i). As for ED have investigated early post-cavernous nerve these drugs interfere with the nitric oxide (NO) – cyclic injury applications of stem cells, most often guanosine monophosphate (cGMP) pathway, an intact intracavernous, in rat models. The first report on stem NO supply from the nerves and endothelium is cell application was published in 2004 by Bochinski et needed to guarantee the efficacy of these agents. al. form the Lue laboratory in San Francisco (US)6. Several prevalent diseases reduce the bio-availability of NO and men with these underlying pathologies, What we have learned from a series of animal studies such as diabetes, commonly don’t respond as well to by diverse groups worldwide, is that stem cells PDE5i as patient without these comorbidities. improve functional recovery of ED in the setting of Available pharmacological treatments are effective in cavernous nerve injury, and that stem cell recruitment about 60% of patients and mostly well tolerated, but to the injured nerves and ganglia is important3 in some patients usage is limited by the frequent (See Figure 1). It is currently believed that stem cells occurrence of bothersome side effects, such as release local factors which can act trophic, headache, dyspepsia and muscular pains. immunomodulatory, antifibrotic or as stimulants or inhibitors of other biological processes. Hence, Loss of spontaneity mesenchymal stem cells are often referred to as an Most of these treatments take the spontaneity out of sex “injury-drugstore”7.

Patients models of ED including aging, diabetes mellitus and experiencing treatment failure or adverse events now hyperlipidaemia. In chronic ED the mechanism of face no other choice than to resort to more invasive action is presumed to be by engraftment and options such as intracavernous injection, vacuum transdifferentiation, which differs from the paracrine devices and finally penile prosthesis implantation. action seen in acute disease models such as CNI. However, the evidence supporting this notion often Besides these well-known limitations to the currently relies on rather poor methodology3. available treatment armamentarium, these modalities are solely providing symptom relief and do not Stem cell therapy: too early, too risky? provide a permanent improvement of the condition or To come back to the initial question whether stem cell an increase in spontaneous erections by targeting the therapies in ED are too early or too risky, the answer underlying pathophysiological processes1. Notably is quite easy. Too early yes, too risky likely not. A however, in a 1998 study published at the time of variety of stem cell sources can be used for the marketing of the first available PDE5 inhibitor treatment of degenerative diseases and injury. So far, only bone marrow stem cells and adipose stromal sildenafil, the highest rank measure of treatment vascular fraction have been tested in ED clinical trials. success in terms of importance for ED patients was ’cure’2. A cure for ED resulting in spontaneous Bone marrow aspiration yield BMSCs for injection unassisted intercourse entices research into novel either after culture or uncultured as whole mononuclear fraction, of which 83 per 1 × 106 cells are regenerative treatment methods, and besides low-intensity shock wave application and platelet-rich mesenchymal stem cells (MSC). ADSCs from adipose plasma (both of which will be discussed in the tissue are easily harvested, either as a component of abstract sessions at this year’s Annual EAU Congress), the so-called ’stromal vascular fraction’ (stem cells in stem cell therapy is one of these options currently fat residue in the perivascular niche) of the adipose explored3,4. While a wealth of animal data have been tissue, containing around 560 MSC per 1 × 106 cells, or gathered over the last 15 years, human data are still as a purified stem cell population after successive scarce while in commercial clinics, autologous stem culturing. Adipose tissue is easily harvested in large cell transplantations are already offered at high cost amounts without major adverse events, and this can for this indication. Therefore the question arises: is it be done under local anaesthesia by liposuction. still too early or too risky to treat patients suffering Harvested fat tissue or lipoaspirate is processed from ED with stem cell therapy? mechanically and incubated with collagenase to remove the extracellular matrix.

Presence of adipose-derived stem cells (ADSC) at the rat major pelvic ganglion (MPG) 7 d after cavernous-nerve crush (as a model for post-radical prostatectomy erectile dysfunction) and intracavernous injection with 5-ethynyl-2-deoxyuridine (EdU)–labeled ADSC. S-100 protein was used to stain for nerve fibers, EdU staining for ADSC, and DAPI for nuclear staining. This image shows that even though stem cells where injected in the penis, they can be detected at the site of the injury several days after injection, and illustrates their migratory capacity.

al. treated 17 patients post-radical prostatectomy with intracavernous injection of adipose tissue derived regenerative cells and concluded that 6 months after injection, 8 (47%) men recovered their erectile function and were able to accomplish sexual intercourse9. All these men had also regained continence, which therefore may be a predictor for stem cell response or a proxy for nerve-sparing status. Overall, the IIEF-5 score gain was in the range of 10 points. In an update paper, this effect was sustained at 12 months10. Interestingly, in this study no effects were seen at 1 month post-injection which argues against placebo effect and pro induction/stimulation of regenerative processes. Rene Yiou and colleagues used intracavernous injection of bone marrow mononuclear cells in post-radical prostatectomy patients suffering from ED in the INSTIN phase ½ trial which included dose-finding. They concluded that erectile function was statistically significantly improved after 6 months in the patients given 1×109 cells, with IIEF-EF domain scores 18±8.3 vs 3.7±4.1 (baseline)11. No serious side effects occurred after a mean follow-up of 62.1 months in the first 12 patients, and no elevated risk for prostate cancer recurrences were seen12. Al Demour et al. contributed to the literature with a single arm phase 1 trial published in 2018, in which 4 diabetic ED patients experienced no side effects but an IIEF-EF improvement of about 12 points after intracavernous injection of autologous bone marrow derived mesenchymal stem cells13. All patients on placebo While these are all phase 1 open label non-controlled trails, the authors made claims on efficacy in all instances. This is troublesome as 1. a large proportion of these patients was prone to experience spontaneous ED improvement (inclusion relatively short after nerve sparing radical prostatectomy) and 2. placebo effect can be very prominent in ED research. To illustrate this, De Araujo and co-workers designed a prospective, controlled, single-blind, parallel-group study with 123 patients with ED: all patients got placebo treatment. Even though patients were aware of this, they experienced an average IIEF-EF score increase of 4 points14. The important lesson to learn from these data is that ED patients under active treatment in a study setting are likely to experience an improvement in their IIEF scores. Hence, single-arm studies and open label non-controlled trails are to be viewed as hypothesis generating and should not be included in an evidence review aimed at making practice recommendations or guidelines. In all studies that have been reported, side effects have been limited to minor side effects, such as mild pain or bruising at the site of harvesting (adipose tissue or bone marrow) or at the site of injection (penis). No recurrences of prostate cancer have been seen in patients following stem cell injections. Hence, the conclusion that we can draw today is that regenerative cell-based therapy for erectile dysfunction is probably safe and may be functionally beneficial. Data of phase 2 trials are underway to confirm these data in small RCTs, after which phase 3 trials are expected. Until we have the data from these trials, we cannot recommend this treatment in any of our ED patients, except for those included in trials.

Herbal treatments for renal stones: Myth or fact? Mr. Samih Al-Hayek Cambridge University Hospitals, Cambridge (UK)

Urolithiasis is a common condition with an overall prevalence of 10.6% in men and 7.1% in women1 and a lifetime risk of about 13% in men and 7% in women in Western countries2. Acute presentation with pain (colic) peaks in young and middle-aged active people affecting their work and costing billions. It is a recurring problem with risk of 35-50% of having another episode in 5 years and 80% in 10 years. Medical treatment of stones There have been significant advances in diagnosing urinary tract stones with improved imaging and in their treatment. The various energy sources (LASER, ultrasound, pneumatic...), allowed us to use a wide range of minimally invasive treatment interventions including Extracorporeal Shockwave Lithotripsy (ESWL), ureteroscopy (optic and digital including robotic), standard, mini and ultra-mini percutaneous nephrolithotomy (PCNL).

“However, we only have limited options to treat stones with medical therapy and even less options for primary or secondary prevention.” We have reasonable knowledge about the pathophysiology and the theories behind the formation of crystals leading to the formation of stones, including genetic factors. However, we do not seem to be able to intervene medically to interrupt the formation cycle and avoid the final product (stones). Currently, we use potassium citrate to alkaline the urine - which mainly helps the dissolution and prevention of uric acid stones, to a much lesser degree, calcium oxalate but the dosage, duration and actual effect are not standardised. Thiazides can help to reduce the excretion of calcium in urine and allopurinol can reduce urate, but compliance is poor and overall outcome is variable. Is herbal therapy the answer? Those who have experienced renal colic once do not want to go through the same pain again. They seek advice on how to prevent stones, but urologists have limited options to offer. Patients find dietary advice difficult to follow and get frustrated when we keep advising them to increase fluid intake. Desperate to find a solution, they search the internet that is full of magic herbal ‘cure’ options for dissolving existing stones and stopping them from coming back. The options vary from something as simple as fruits and vegetables and natural products to more complex formulated tablets. But do they really provide ‘cure’ and are they safe to use?

Table 1: list of some herbs used for treating urolithiasis (courtesy of Dr. A. Trinchieri, IT) clinical studies in healthy volunteers at that point were studies to test citrus or cranberry juices which affect citrate excretion. A more recent systematic review by Elena Monti et al in 20154 has screened 541 articles and only 16 studies were eligible for inclusion. There was a significant degree of bias, heterogeneity and poor level of evidence with a small number of participants and a short study period. Most of the studies did not specify the stone composition, the imaging modality for follow-up, comparison data or clear randomisation method. Another review by Russel et al5 for the herbal remedies used in India and China also indicated that there are some products with reported efficacy, but the evidence is not strong enough to establish their use routinely. The results of those limited studies and reviews are summarised below: Effect on urine: • Calcium: Agropyrum repens and Wu-Ling-san had no significant effect on calcium excretion compared to placebo • Urate: the above herbal therapies also showed no significant effect on urate excretion • Oxalate: 1 out of 6 studies reported on intergroup differences and Agropyrum repens had no significant effect Effect on stone size: • Crataeva magna plus Musa paradisiaca versus placebo: • 33.04% reduction in size was documented in the active arm, versus a 5.13% increase in the placebo arm if original stones were less than 10 mm (p = 0.017) • In the large stone group (over 10 mm), no significant inter-arm differences in size reduction were found • A study comparing Orthosiphon grandiflorus infusions with citrate evaluated the rate of stone size reduction per year (ROSRPY) at different time points up to 18 months. No significant differences were found between treatment arms at any point • Celosia argentea, a putative litholytic agent, was found to reduce stone size to a greater extent than citrate, after 6 months of therapy (-2.57 mm versus -1.82 mm, respectively; p < 0.05)

Effect on stone number: • In an open-label study comparing Phyllantus niruri with no treatment in post-lithotripsy patients, 90.6% of patients treated with the plant Possible mechanisms of action extract were free of lower caliceal stones (without It is not clear how most herbal therapies work.

The lack of a standardised • Didymocarpus pedicellata (DP) combined with method of cultivating the plant and the process used another herb (Cystone).

Herbal products may not affect the inducing size reduction (mean difference: urinary risk factors (exertion of calcium, oxalate, urate, DP preparation, 4.93 mm lower; p = 0.02) and citrate) but might have a direct effect on the process of total clearance but there was no effect on crystallisation.

Side effects A few studies did not mention anything about possible side effects. Eight studies reported no adverse events or side effects, nor any complaints from treated patients. One study reported nausea, giddiness, epigastric pain. Those taking citrate, reported fatigue and loss of appetite in 26% patients with no complaints in the herbal agent arm (no statistics available). In the Singh 2011 study, citrate induced upper GI disturbances with no adverse events were recorded in the cohort treated with herbal. In the Premgamone 2009 study on the effect of Orthosiphon grandiflorus (OG), placebo showed significantly higher adverse effects after 14 days of therapy (treatment arm 2.8% patients, placebo arm 17.5% patients with adverse events; p = 0.03). In the Shekar Kumaran and Patki trial, vomiting, gastric irritation and dyspepsia were recorded in three different patients belonging to the group treated with the DP preparation. Conclusion There is a large number of advertised herbal products that claim to be a cure for urolithiasis patients by dissolving existing stones or preventing new ones in the future. There is no clear supportive scientific evidence for many of those products. The mode of action, the active component, the way of extraction are not clear and the dose and duration of treatment are not standardised or validated. There are some clinical trials that included small numbers of participants over a short duration, but they are of low quality, have a high level of heterogeneity and risk of bias.

“There is an unmet demand for medical therapy to help dissolve stones and prevent recurrences. Herbal products might have a potentially promising role.”

The herbal products did not seem to have any effect on calcium, oxalate or urate exertion in the urine. Herbal formulations containing Didymocarpus pedicellata (DP) combined with other herbal agents were superior to placebo in inducing size reduction and total clearance of renal and ureteral stones, whereas pooled analysis of three studies with low quality of evidence showed that citrate treatment was able to decrease the mean stone size and urate excretion more than phytotherapy. There is an unmet demand for medical therapy to help dissolve stones and prevent recurrences. Herbal products might have a potentially promising role. However, in the current format it is not safe to endorse the available products until large wellstructured studies look into their efficacy and safety. These studies are urgently needed to help guide our desperate stone patients. References 1. Charles D. Scales Jr., Alexandria C. Smith, Janet M. Hanley, Christopher S.

From the EAU Scientific Congress Office

Culig: “Important to invest more in experimental urology” Newly-appointed Professor of Experimental Urology reflects on achievements of SCO Prof. Zoran Culig (Innsbruck, AT) is a long-serving member of the Scientific Congress Office (SCO), advising on abstract selection and the design of the scientific programme for the EAU’s Annual Congress since 2012. He was recently promoted to Professor of Experimental Urology at Innsbruck Medical University, one of four people to hold this position in Europe.

“For instance, during the Congress in London (EAU17), the experts who represented different fields gave wonderful presentations and showed all of us how urological research should be developed.”

“In my view, the Scientific Congress Office is primarily responsible for preparing the program of the Annual Congress. For this purpose, there are two meetings during the year. During the first meeting, plenary and thematic sessions are discussed. The second meeting, closer to the congress is more important for selection of abstracts.”

“With considerable progress in worldwide scientific research, the EAU’s Scientific Congress Office could, in my opinion, become involved in more activities in future. Scientific policy in Europe could also be discussed during the committee’s meetings, especially if we consider the fact that in the United States there is much more money for multi-institutional collaborations. Unfortunately, we do not see the same Prof. Zoran Culig (right) trend in Europe and joint projects between urological researchers from different nations is very difficult at present. The SCO could potentially help facilitate this.” publications in oncology, pathology, and endocrinology journals but also to some prestigious Experimental Urology awards.” Starting on January 1st, Prof. Culig was appointed Professor of Experimental Urology at Innsbruck From his new academic position, Prof. Culig is looking University. Prof. Culig was appointed based on his to increase the involvement of urology researchers at previous work in urological research, covering a earlier stages of drug development: variety of topics. “I strongly believe that basic and translational “The main part of my earlier research was devoted to researchers have to be involved in studies on possible studies on therapy-resistant prostate cancer, in drug resistance at earlier stages of drug development. particular to endocrine therapy and chemotherapy It should be clear to all participants in the process resistance.

Urology in Europe and considers his appointment a This research led me not only to a large number of significant honour.

Prof. Culig joined the SCO at the invitation of then-EAU Secretary General Prof. Abrahamsson and SCO Chairman Prof. Stenzl. “I cover a large number of basic and translational research topics, in particular those in prostate, urothelial and renal oncology.” “For a while, I was both chairman of the EAU Section of Urological Research (ESUR, now chaired by Prof. Kerstin Junker) and a member of the SCO. This was a very challenging time period with many meetings and tasks to be done for the European Association of Urology.” Looking back on seven years on the SCO, Prof. Culig is particularly proud of the level that the congress’s thematic sessions on urological oncology reached. “From feedback received from urologists and urology-related scientists, I am pleased to hear that we brought thematic sessions in urological oncology to a very high level. I liked discussions between basic and clinical scientists in which we addressed key issues of therapy resistance, such as cellular stemness.”

As urology and specifically urological research continues to evolve, Prof. Culig considers the time ripe for a shifting role of the SCO:

“I am very grateful to Professor Wolfgang Fleischhacker, Rector of Innsbruck Medical University and his Vice Rectors for selecting me for the professorship. It will give us more stability to improve plans for future research and to coordinate research activity, submissions of grant applications and publications.” “My goal is to keep a relatively high number of academic positions in the field of Experimental Urology in Innsbruck and to offer new opportunities for career development. In particular, a stay abroad for outgoing PhD researchers will be arranged. Other professorships have been established in the Netherlands, United Kingdom and Finland, and all of these positions are important to provide appropriate research environment in Europe. “Because of a high prevalence of urological cancers in Europe, it may be very important to invest more in experimental urology professorships in other countries.”

Is there evidence on how to treat late-onset hypogonadism? The main causes are obesity, inactivity and chronic diseases Prof. G.R. Dohle Dept. of urology Erasmus MC Rotterdam (NL)

Male hypogonadism is a condition characterised by symptoms and low testosterone levels. It can occur early in life and cause congenital malformations of the male genitalia (cryptorchidism, hypospadias, short anogenital distance), delayed puberty and male undervirilisation in adult life. With age, testosterone levels decline. In some men this results in late onset hypogonadism (LOH). Symptomatic male hypogonadism occurs in 2 to 5% of men above 50 years of age1.

Symptoms With age testosterone will decline with 0.5 to 1.5% per year2. Also, Sex Hormone Binding Globulin (SHBG) will increase with age. As a consequence, bioavailable (free) testosterone will reduce further. This may cause symptoms of low testosterone, but at least half of the men with low testosterone are without hypogonadal symptoms. Furthermore, symptoms associated with male hypogonadism also occur in men with normal testosterone. Table 1 highlights the symptoms of late onset hypogonadism. Common symptoms of men with low testosterone are sexual dysfunction, loss of vigour, frailty, insomnia, unexplained anaemia, cognitive dysfunction and depression. Only sexual symptoms have a significant association with low testosterone, other symptoms are less specific. Symptoms of testosterone deficiency are also depending on individual androgen sensitivity: some men may need more testosterone than others. Testosterone deficiency is common in men with obesity, chronic diseases, men with low-trauma fractures, low sperm count, testicular dysfunction and small testes. In these men testosterone measurement can be considered. Current guidelines, however, advise against routine screening for hypogonadism in ageing men.

In contrast to testosterone therapy for congenital forms of male hypogonadism, testosterone treatment in ageing men is controversial, because of unclear indications for replacement and potential risks in older men. Ageing men develop low testosterone levels mainly due to overweight, inactivity and chronic “Restrict the diagnosis of testosterone diseases.

Gels and injections are the mostly prescribed applications (see table 3). The aim is to restore testosterone to physiological levels. Guidelines advice to start with a short-acting application first to observe improvement of symptoms and monitor side effects. Risk of testosterone treatment Testosterone treatment is associated with some potential risk factors: an increase of red blood cells and an elevation of prostate specific antigen (PSA) may occur. The consequences of these laboratory observations are unclear, but erythrocytosis may result in an increased risk for thrombosis and an elevation of PSA indicate prostate growth and a higher chance of developing prostate cancer. Current RCTs, however, are too small and follow-up is too short to estimate the associated risk of developing thrombosis and prostate cancer under TT. Observational studies do not indicate a higher risk for thrombosis or prostate cancer in men undergoing TT, but monitoring haematocrit and PSA remains advisable. Contraindications for TT are locally advanced and metastatic prostate cancer. Also, men with an active wish for children should not use testosterone, since it inhibits spermatogenesis.

“There is no substantive evidence that testosterone treatment, when supplemented to the normal physiological range, is related to the development of major adverse cardiovascular events” Source: EAU guidelines on male hypogonadism 2017 Key points 1. The main causes of male hypogonadism are obesity, inactivity and chronic diseases 2. Sexual symptoms in ageing men are most predictive for low testosterone 3. Life style changes are the first-line therapy for the treatment of late onset hypogonadism: lose weight, become active, treat comorbidities as good as possible. This may normalise testosterone levels and reduce associated health risks, such as type 2 diabetes mellitus and cardiovascular diseases. 4. Indications for screening and treatment of LOH are multiple symptoms of hypogonadism, sexual symptoms, and to a lesser extent loss of vigour and depressive symptoms. 5. Men on testosterone treatment should be regularly evaluated for prostate health, erythrocytosis and cardiovascular symptoms.

• Myocardial infarction or stroke within the last 6 months • Thrombophilia

In contrast, one RCT comparing phosphodiesterase-5 inhibitors (PDE5i) with PDE5i and TT did not show an additional benefit of TT over PDE5i alone5. Men with erectile dysfunction can first be treated with a PDE5i, since this is an effective treatment with little side effects. In case of poor response to PDE5i testosterone is measured and, if low, TT is added. It will take at least 3 months of TT before improvement of sexual function will occur. Other symptoms that may improve under TT are walking distance, mood, depressive symptoms, anaemia, and bone density, but all to a very modest degree. TT did not improve vitality and cognition in recent RCTs.

“Treatment should be restricted to adult men with low testosterone and consistent and preferably multiple signs and symptoms of hypogonadism following unsuccessful treatment of obesity and comorbidities”

Cardiovascular risks Hypogonadal men have an increased risk of obesity and cardiovascular events. This relationship could be explained by a poorer health condition in men with low testosterone. However, also men with congenital forms of hypogonadism, such as Klinefelter patients, have an increased risk for obesity and associated health problems. A randomised trial indicated that TT may result in a higher risk of cardiovascular incidents, especially in men over 65 years of age. Also, in one study TT was associated with an increase in coronary artery plaque volume. Large retrospective and observational studies could not confirm these observations: meta-analyses of observational and randomised studies do not show an increased risk for major cardiovascular events (MACE) in men undergoing TT7. Also, The European Medicines Agency (EMA) concluded that there is no consistent evidence of an increased risk of coronary heart disease associated with TT in hypogonadal men8. Still, men with uncontrolled cardiovascular disease should first consult a cardiologist before starting TT, since it may result in heart failure in these men. Monitoring of men treated with testosterone consists of clinical assessment, haematocrit (not exceeding 0.54), PSA (not exceeding 4.0 ng/ml) and testosterone levels maintained within the mid-normal healthy range.

Beyond BCG in non-muscle invasive bladder cancer Overview of non-muscle invasive bladder cancer treatments over the past decade Prof. Ashish M. Kamat Professor of Urologic Oncology (Surgery) University of Texas MD Anderson Cancer Center (US) akamat@ mdanderson.org

Justin T. Matulay Urologic Oncology Fellow University of Texas MD Anderson Cancer Center (US) jtmatulay@ mdanderson.org Intravesical administration of bacillus CalmettéGuerin (BCG) has been the cornerstone of management for non-muscle invasive bladder cancer (NMIBC), the 10th most common malignancy worldwide1, for nearly half a century since the original work performed by Alvaro Morales in the 1970s2. To this day it remains first-line intravesical therapy for intermediate and high-risk NMIBC with proven efficacy over other agents in direct head-tohead comparisons. Despite its status as the most effective immunotherapeutic drug in oncology, BCG has well-known limitations and drawbacks. The randomised controlled trials demonstrating the superiority of BCG do so with regard to tumour recurrence and progression but results on survival outcomes are less robust. Additionally, in order to derive these benefits BCG must be given as maintenance therapy for 1 to 3 years, which some urologists find hard to do despite evidence that, most patients can complete a full course of 3 year maintenance3. Failure of BCG therapy, either because of intolerability or lack of efficacy, leaves the patient in the precarious position of choosing between radical cystectomy (RC) and bladder preservation strategies with varying efficacy. Those patients with high-grade carcinoma in situ (CIS) and/or T1 disease face a risk of progression to life-threatening muscle-invasive bladder cancer (MIBC) that is over 50%. What follows is a review of the current options for BCG failure, including clinical trials and experimental therapies, as well as potential alternatives and adjuvants for the treatment-naïve patient (see Table). Risk Stratification There is a wide spectrum of NMIBC, ranging from small, low-grade papillary tumours to T1 tumours widely invading the lamina propria and subepithelial lymphatics. Risk stratification is paramount in determining whether or not an individual patient should be offered BCG therapy with the goal of minimising toxicity for those at lowest risk of progression while maximising efficacy in higher risk disease. Certain clinicopathological characteristics – high volume T1, T1 with CIS, persistent T1, lymphovascular invasion and/or variant histology – denote a very high-risk subgroup that may benefit from an immediate RC, in spite of the morbidity and impact on quality of life4,5. These special circumstances aside, the urologist is more likely to be seeking alternatives to BCG therapy following therapeutic failure. Definition The term ‘BCG failure’ has taken on several different meanings throughout the years, leading to a heterogeneous cohort of patients with this designation included in clinical trials studying BCG alternatives. On the advice of experts such as the Group at ASCO GU and the International Bladder Cancer Group (IBCG), the Federal Drug Administration of the United States has adopted a unified definition of BCG failure. An important new subgroup consists of the ‘BCG unresponsive’ tumours, where further BCG instillations are unlikely to prove beneficial6. In this population, radical cystectomy is the only proven salvage therapy, and as such, patients entering clinical trials should not be offered a placebo treatment as a control arm, thus making single-arm studies acceptable7. 10

Intravesical Chemotherapy Intravesical chemotherapy is the most frequently studied option in BCG failure; the only FDA-approved drug is valrubicin (Valstar®) but it has minimal efficacy. Other agents include gemcitabine, docetaxel, paclitaxel, cabazitaxel, cisplatin and combination therapies. In small, early phase trials, initial response rates with single agents are often very good (over 50%), however, after 1 year of therapy, durable responses range from only 16 to 40%7. The combinations hold more promise: intravesical gemcitabine/docetaxel has demonstrated good durability – 34% freedom from HG recurrence at 2 years8. Triple therapy with cabazitaxel/gemcitabine/ cisplatin has also been reported9. Our practice, at the time of writing, is to offer combination intravesical chemotherapy with gemcitabine and docetaxel to patients with BCG unresponsive disease who refuse radical cystectomy and are not candidates for clinical trials. Nanoparticles can be loaded with specific drugs to increase delivery to the urothelium over the solubilised drug alone. Albumin-bound nanoparticles loaded with paclitaxel and delivered intravesically had an initial CR rate of 36%, although only 18% remained disease-free after 3 years10. Docetaxel (NCT02982395) and rapamycin (NCT02009332) loaded nanoparticles are being studied in early phase human trials.

Table 1: Alternatives and adjuvants for BCG-unresponsive non-muscle invasive bladder cancer

Radiofrequency-induced chemohyperthermia Radiofrequency-induced chemohyperthermia (CHT) with mitomycin C (MMC) has shown benefits over MMC alone in an open-label RCT as initial treatment for intermediate and high-risk NMIBC patients (2-year RFS 82.9% versus 42.5%, p < 0.01)11. However, when compared to BCG in another RCT, there was no statistically significant difference in the 2-year RFS endpoint between CHT and BCG (78.1% versus 64.8%, p = 0.08), each given with 1 year of maintenance therapy12. Limited data exist for CHT in the setting of truly BCG unresponsive disease, but in a post-hoc analysis from a prospective study of CHT, 55 BCG unresponsive patients were observed to have 1-year RFS of 47% and a median disease-free interval of 17.7 months13.

more robustly to intravesical BCG exposure if the patient is first exposed systemically to an intradermal BCG vaccine. Specially designed vaccines containing tumour-specific proteins purported to increase the immune response of the tumour microenvironment have been studied in trials in combination with intravesical BCG. PANVAC (containing viral transgenes for CEA and MUC-1 plus co-stimulatory molecules)19 and HS-410 (containing heat shock proteins)20 have both reported data showing an enhanced immune response in tumour tissue. A genetically modified BCG vaccine, VPM1002, shows increased immunogenicity and is being studied in a phase I/II study. The vaccine Ty21a has been in use for several decades against typhoid and is now being studied clinically as an intravesical alternative to BCG (NCT03421236).

Additionally, photodynamic therapy (PDT) with newer, improved sensitising agents are being studied in early clinical trials in Canada. Conclusion The landscape for treatment of NMIBC has evolved rapidly over the past decade with the recognition of the need to move beyond BCG, not only to salvage patients who fail BCG therapy but also for who cannot tolerate it. Notably, the recent spurt in agents has been spurred not only by better understanding of the mechanisms that affect resistance to BCG therapy but also because of unified definitions of the different post-BCG disease states. Approaches using combination chemotherapy regimens, improved drug delivery, gene manipulation and immunotherapy all hold promise for the future of bladder preservation in this patient population. This is even more relevant as we currently are facing a worldwide shortage of BCG. Editorial Note: Due to space constraints the reference list has been shortened.

Professor of Urology University of Eastern Piedmont Novara (IT) ale.volpe@me.com In collaboration with the EAU Research Foundation, Prof. Alessandro Volpe of the University of Eastern Piedmont in Novara, Italy, is coordinating a multinational prospective longitudinal study to collect data on patients with small, incidentally detected, histologically confirmed renal cell carcinomas (RCCs) who are managed with active surveillance (AS). This observational registry is called European Active Surveillance of Renal Cell Carcinoma (EASE) study. On Sunday March 17 at 9 am, during the annual EAU congress in Barcelona, an investigator meeting will take place to present the status of the study to urologists from the institutions that have already joined the project or would like to participate. Rationale AS is a reasonable strategy for the management of small renal tumours in patients with advanced age or significant comorbidities. The evidence on AS is mainly based on retrospective and single institutional studies with relatively short follow-up. Moreover, the assessment of the oncological outcomes in these series can be biased by the presence of benign tumours since histological confirmation of malignancy was obtained only in a proportion of cases. EASE is the first multicentre prospective study on AS that includes only patients with histologically proven RCC by percutaneous biopsy at enrolment and has therefore the potential to clearly define the oncological outcomes and the clinical role of this conservative approach for small RCCs.

With the expansion of treatment options for small renal masses, it is also increasingly important to identify reliable biomarkers that can differentiate tumours with different aggressiveness and metastatic potential at diagnosis, thereby enabling the urologist to choose the most suitable conservative or active management approach for the individual patient. EASE will contribute to reach this goal since serum, urine and tissue specimens will be stored at baseline and at the time of tumour progression for the assessment of genomic and molecular predictors of fast growth and progression of small renal tumours. Objectives The primary objective of EASE is to assess the overall survival of patients who are diagnosed with incidental, histologically (biopsy) confirmed, <4 cm RCC and are managed conservatively with AS and to demonstrate that overall survival in this population is not significantly different compared to the overall survival of the general population without RCC and with similar age and comorbidities; The secondary objectives are: • the growth rate and progression rate of small renal tumours in AS; • the cancer-specific and progression-free survival of renal tumours in AS; • the identification of clinical and pathological predictors of fast growth rate and progression for small RCCs; • the identification of serum, urine and tissue predictive markers of fast growth rate and progression of small RCCs.

RCC. Biopsies are carried out under local anaesthesia with ultrasound or CT guidance. At baseline, information is collected on demographics, medical history, tumour-related symptoms and performance status. A physical examination is performed and blood and urine is collected. Abdominal imaging is performed by contrast-enhanced CT scan and MRI or, in case of contrast allergy or abnormal serum creatinine, by ultrasound. All patients follow a standardised AS protocol. Follow-up visits are scheduled three and six months after diagnosis, every six months up to three years and yearly thereafter. A follow-up visit is also carried out at the time of progression when it occurs. Follow-up visits include medical history, physical examination and assessment of performance status, serial abdominal imaging and quality of life and anxiety by dedicated questionnaires. Biopsy material at baseline and at the time of tumour progression, as well as voided urine and blood samples at definite time points are collected and stored for assessment of predictive biomarkers. The translational analyses are centralised at the Francis Crick Institute in London, where a group of scientists led by Dr. S. Turajlic is leading the research in this field. Electronic Case Report Form The web-based database management system Marvin is used for collection of patient data. The system is intuitive and easy to use.

Study status More than 65 institutions across Europe and some Patient population from other continents have shown interest to include A total of 400 patients with small, incidentally patients in the EASE registry. Seventeen centres from detected, histologically confirmed RCCs will be included and data related to the oncological outcomes Italy, the Netherlands, Spain, Austria, Finland, Iceland, Lithuania, Turkey and Argentina already obtained of the AS approach will be collected. ethics approval and started recruiting patients.

Penile cancer: Organ-sparing surgery Preservation of penile length and improved cosmetic outcomes are the standard of care Mr Asif Muneer Consultant Urological Surgeon and Andrologist, Associate Professor, Male Genital Cancer Centre NIHR Biomedical Research Centre, University College London Hospital, London, UK

Penile Preserving Procedures The type of penile preserving procedure will depend on the size and site of the lesion as well as the degree of local invasion. Since the majority of primary lesions are located on the glans penis or prepuce, the corporal bodies and penile shaft skin can be preserved. The advances in imaging techniques using penile MRI with an artificial erection allows surgical planning (see Figure 1). By performing pre-operative penile imaging, the degree of infiltration into the corpus spongiosum or into the tips of the corpus cavernosum can be assessed.

Primary penile cancer is a rare male genital malignancy in Western Europe and North America, accounting for approximately 0,2-0,6% of all malignancies. However, in parts of South-America, Asia and Africa, penile cancer can comprise 1-2% of all malignancies. Histologically the majority of these lesions are squamous cell carcinoma (SCC) which represent over 95% of all penile cancer cases.

Management of small glans and foreskin lesions 1. Circumcision ± wide local excision Approximately 30% of lesions are limited to the foreskin or may extend onto a small area of the glans penis. Undertaking a circumcision with a wide local excision of any extension of tumour onto the glans is safe, provided that additional biopsies are taken of the base of the tumour to Although there are specific risk factors such as ensure that there is a tumour free margin.

Male infertility: An indicator of male health status? An intriguing hypothesis Prof. Andrea Salonia Division of Experimental Oncology/Unit of Urology University Vita-Salute San Raffaele Milan (IT)

The hypothesis that men with male factor infertility may have a lower general health status has been widely corroborated throughout the last few years. As a matter of fact, the relationship between health status and male fertility is a closely intertwined one, since several conditions known to negatively impact men’s health have been repeatedly associated with impaired reproductive functioning. This implies a wide range of alterations going beyond the well-known 20-fold increased risk of testicular cancer described in men with abnormal semen analyses1,2. Colorectal cancer, melanoma and prostate cancer3,4 along with a higher rate of certain noncancerous disorders5 seem to be associated with male infertility. Urogenital and systemic infections6, autoimmune diseases7, endocrinopathies and metabolic disorders8, as well as chronic kidney and liver disorders9,10 have all been alleged, and often confirmed, factors known to detrimentally influence fertility. Mortality decreased as sperm concentration increased General health status has been inquired in several ways in infertile men, with specific outcomes differently varying according to the analysed study, ranging from life expectancy up to general health related indexes and isolated comorbidities. First reports by Jensen et al.11 found that mortality decreased as the sperm concentration increased up to a threshold of 40 million/ml; moreover, mortality decreased in a dose-response manner as the percentages of motile and morphologically normal spermatozoa and semen volume increased. Likewise, Bonde et al.12 also reported an increase in the probability of conception with increasing sperm concentration up to the same threshold of 40 million/ ml, thus eliciting a direct association between fecundity and general health status. Comorbidity index Dealing with life expectancy in infertile and, therefore, usually young men may be simultaneously intriguing and way too speculative. In this regard, existing comorbidities indexes would be somehow better fitted in the subfertile population. Recently Eisenberg et al.13, observed that by stratifying their large cohort of infertile men using the Charlson Comorbidity Index (CCI), differences in all measured semen parameters were identifiable. Men with diseases of the endocrine, circulatory or genitourinary systems, or skin diseases all showed significantly higher rates of semen abnormalities. Notably, the CCI estimates overall disease burden giving an appraisal

of the related mortality risk14. These results were later confirmed15 considering semen parameters, further adding interesting insights in terms of hormonal values: infertile and less healthy patients were found to have lower testosterone and higher follicle stimulating hormone values; moreover, patients with sperm concentration lower than 45.6 million/ml were at higher risk of having comorbidities. Though being somehow reductive, the use of comorbidities indexes gives an appraisal of the general health status as compared with the analysis of a single subset of comorbidities. Overall, this is of major importance when dealing with young men, where the comorbidity burden is seen as more familiar as compared to the idea of life expectancy. Possible links between low general health status and male infertility Several authors attempted to explain the relationship between health status and male infertility. Recently, Ventimiglia et al.15 hypothesised two different mechanisms to explain the coexistence of infertility and comorbidities: the existence of a common mechanism promoting both infertility and a particular subset of associated pathological conditions; and comorbidities directly interfering with male reproductive function (see Figure 1). Considering the first mechanism, substantial evidence suggests that men with reproductive health disorders may lack certain regulatory genes, predisposing them not only to abnormal spermatogenesis but also to abnormal control mechanisms for cell division and, hence, an increased probability of cancer1-4. To this regard, many DNA repair genes previously identified in cancer syndromes have been found to regulate key processes in gamete production16. Polymorphism as risk factor For instance, a single nucleotide polymorphism in the Lynch syndrome gene MLH1, involved in mismatch repair pathway, was reported as a risk factor in men with azoospermia and oligozoospermia17. Moreover, this single nucleotide polymorphism was associated with increased DNA fragmentation in men with normal sperm concentration as well17. A common mechanism underlying germ cell defects and cancer appears particularly discernible in azoospermic men4. Preclinical data from a mouse model lacking DNA repair gene ERCC1 confirms this association18. To this regard, the case of cryptorchidism is glaring; undescended testis is associated with impaired fertility and is a major risk factor for testicular cancer. Postnatal germ-cell development deteriorates in the undescended testis after the first year with the consequent risk of infertility increasing with age19. Moreover, the relative risk of testicular cancer among these patients doubles if orchiopexy is performed after reaching 13 years of age20. Apart from the genetic background alleged to partially link cryptorchidism to both testicular cancer and infertility [16], data showing an association between delayed orchiopexy and an increased rate of cancer/infertility clearly suggest a major role for ‘local environmental factors’ as well.

Comorbidities with detrimental effect Alternatively, it may be the case that comorbidities have a detrimental effect on male reproductive function. Many of the conditions found in our cohort, which are known to impact reproductive function, are extremely common in the male general population. Up to 39% of the adult population in the USA has criteria suggestive of metabolic syndrome (MetS)21; comparable rates were observed in the Italian population22. Similarly, high rates have been observed for dysmetabolic conditions, such as MetS and obesity23, diabetes24 and hypertension25. Although hormonal homeostatic changes (i.e. higher rates of hypogonadism) brought on by MetS (and obesity per se) have been widely reported and accepted26-28, the effects on semen parameters are still inconclusive28,29. Similar findings are reported for diabetes29; indeed, though not univocal, both altered semen parameters and markers of spermatogenesis have been documented in diabetic men29. Although the majority of these potential detrimental factors have been analysed separately, the current data support the idea of a common pathophysiology pathway in which they act together to perturb overall reproductive health. In this context, an excess of peripheral adipose tissue results in increased tT to E2 aromatization, which eventually leads to secondary hypogonadism and reproductive axis derangement30. Moreover, oxidative stress at the level of the testicular microenvironment may result in decreased spermatogenesis and increased sperm damage31, with several other factors being strongly involved in this complex scenario as well7. Notably, all the aforementioned conditions are included in the CCI score or are considered closely related risks. Among other CCI determining diseases, autoimmune and liver diseases are known for their possible impact on male reproductive function8,9,13. In conclusion, the importance of comorbidities in the male reproductive setting is gaining more and more attention and relevance. Therefore, it is fundamental to properly outline the presence of coexisting diseases during the male infertility work-up, since it may reveal of utter importance in terms of etiologic assessment, therapeutic choice and paternity outcomes.

Can we improve the bladder diary? A lecture on behalf of the Japanese Continence Society (JCS) Dr. Satoru Takahashi Dept. of Urology Nihon University School of Medicine Tokyo (JP)

The data obtained from bladder diaries are important for decisions with regard to the treatment strategy and identification of the pathophysiology. Functional bladder capacities are crucial to choose drugs, and voiding intervals are useful information for timed/ prompted voiding and life-style interventions. Nocturnal polyuria may mostly be a cause of nocturia in elderly patients. However, recording the urinary diaries, especially bladder diaries, is a considerable effort for patients and caregivers, and sometimes is difficult in elderly with cognitive impairment.

“...the sigmoid function is effective for grasping the urine storage and voiding pattern and excluding artefactual errors in the continuous measurement of the intravesical urine volume.”

Es#mated intravesical urine volume [ ml ]

Urinary diaries are commonly used, recommended tools in the management of patients with lower urinary tract symptoms (LUTS), especially frequency, incontinence and nocturia. The International Continence Society (ICS) has defined the following three types of urinary diary on the basis of the recorded parameters: micturition charts, frequencyvolume charts and bladder diaries1. Bladder diaries record a full option of the parameters; the times of micturition and voided volumes, as well as other information, such as incontinence episodes, pad usage, fluid intake, and degree of urgency for at least 24 hours.

volume. Recently, a Japanese group has developed an ultrasound-assisted prompted voiding (USAPV) care programme for the management of urinary incontinence in elderly individuals; care workers regularly monitor the intravesical urinary volume of elderly individuals via ultrasonography, and prompt to void when the volume reaches the pre-fixed optimal value. In a randomised clinical trial, they found that the change in daytime urine loss was statistically greater in the USAPV (median, −80.0 g) than in the conventional prompted voiding (CPV) (median, −9.0 g; p = .018) group2. The care burden scale score of caregivers was unchanged in the USAPV group (p = .59) but significantly worsened in the CPV group (p = .010) after the intervention. These findings suggested that USAPV is efficacious and feasible for managing urinary incontinence in nursing homes. In order to further promote the feasibility and utility of measuring the intravesical urine volume with portable ultrasound devices, a new device for bladder volume ultrasound (Lilium -200; Lilium Otsuka Co., Ltd., Tokyo, Japan) has been developed. It can quickly scan the intravesical urine volume and shows a good correlation between its estimated intravesical urine volumes and actual voided urine volumes (see Figure 1). The Lilium -200 can also continuously monitor

Portable ultrasound devices In this decade, portable ultrasound devices have been developed to measure the intravesical urine

the urine volume before and after voiding, which enables to automatically create the bladder diaries (see Figure 2). However, an artefactual error during body movement remains the most confounding matter in the automatically recording voiding diaries (see Figure 1). Novel method to display urine storage Recently, we proposed a novel method for displaying the urine storage and voiding pattern on an approximate curve, which is created with estimated intravesical urine volumes measured every minute with the portable ultrasound device. Quadratic function and sigmoid function were used for approximation, and examination was performed in subjects with different micturition intervals. From these results, the sigmoid function is effective for grasping the urine storage and voiding pattern and excluding artefactual errors in the continuous measurement of the intravesical urine volume (see Figure 3).

In my lecture for the Japanese Continence Society, I will present a recent advancement and possibilities of further innovations of the bladder diary. References 1.

Genetics in bladder cancer Most genetic changes are somatic mutations developed during life Susanne Osanto Dept. Of Medical Oncology Leiden University Medical Center Leiden (NL)

Molecular subtypes Molecular subtypes have been shown to be associated with different survival outcomes and responses to chemotherapeutic and biological therapies, underscoring their clinical relevance for future bladder cancer clinical management (McConkey and Choi, 2018; Chandrasekar et al., 2018; Matulay and Kamat, 2018).

S.Osanto@lumc.nl

Sequencing technology allowed discovery of somatic mutations in individual tumours with a large variation in mutation burden between and within tumour types, ranging from 10s to 1000s of mutations/tumour (Lawrence et al., 2013 and Alexandrov et al., 2013). Bladder cancer ranks third in highest prevalence of tumour mutational burden (TMB). Somatic mutations potentially result in an increased neo-antigen burden. The more mutations, antigens and neo-antigens a patient has, the more likely they will respond to immunotherapy.

clinicopathological features. Class 1 tumours included non-invasive papillary tumours with the highest expression levels of early cell cycle genes. Class 2 included a higher number of pT1 and high-grade cases and were characterised by epithelialmesenchymal transition and APOBEC mutational signatures. Class 2 tumours had a much higher chance of progressing to muscle-invading disease than class 1 NMIBCs. Class 3 expressed a basal-like gene expression signature that corresponds with class 2, with a higher risk of progression to MIBC. The GS1 group of Hurst et al. was very similar to the UROMOL class 1 of Hedegaard, while GS2 was more similar to UROMOL class 2. Such classifications may aid in clinical decision making and future studies should address the question whether GS2/UROMOL class 2 tumours would be treated more aggressively than GS1/URMOL class 1 tumours. Clinical trials test whether FGFR3 targeted of mTOR targeted therapies are more successful in patients with alterations in these genes/pathways.

ESGURS Welcomes new chairman David Ralph reveals ambitions for EAU’s reconstructive section The EAU Section of Genitourinary Reconstructive Surgeons will have a new chairman from EAU19 on. Prof. David Ralph (London, GB) was elected to follow Dr. Rados Djinovic (Belgrade, RS) at a vote held at an ESGURS board meeting during ELUTS18. Prof. Ralph has been a member of ESGURS since its creation as the ESMGS in 1994 before it became an EAU Section in 2001. He has been on the ESGURS Board since 2016, previously serving as an EAU Section of Andrological Urology (ESAU) board member for eight years. As a consultant urologist and Professor of Urology at University College London Hospitals, Prof. Ralph is an expert in male reconstructive urology, particularly ED and penile disorders and gender assignment issues. He is currently president of the Sexual Advice Association, and previously held positions as President of the European Society for Sexual Medicine, Chair of the International Consultation of Sexual Medicine and board member of the European Society of Andrological Urology. Prof. Ralph has been an EAU member for more than 25 years, and also served the European School of Urology as a faculty member at several events. We asked him about his field and the future of the EAU’s reconstructive Section: What do you see as the biggest developments and challenges in genitourinary reconstructive surgery? Recently, the field has started making use of robotic surgery, mainly for bladder and upper tract procedures. This replaces traditional large open procedures. Robotics are of course also widely used for prostate surgery, offering better post-operative morbidity and fewer unwanted late effects.

Prof. Ralph (right) is an extremely experienced reconstructive surgeon with a long history of association with ESGURS and the EAU. Here he is pictured here chairing a session during ELUTS18 in Milan together with Prof. Carlo Bettocchi (centre)

to grow new urethras in the lab? Are penile and bladder transplantation becoming feasible? What is the role of ESGURS in the wider “reconstructive landscape”? What is the role of its chairman?

The Section’s, and indeed the chairman’s role is to bring together and integrate all areas of genital reconstruction. Furthermore, it is essential for us to bring the younger generation of urological surgeons into our specialty. My main aim is to increase the membership and to explore We are all reconstructive surgeons: we can be a victim the possibility of a publication dedicated to our field. of our own success by pioneering stem cell therapy and transplantation, ultimately replacing the What are your priorities for ESGURS in the coming operations that we currently perform. Will we be able years?

We currently have two section meetings per year. I would like us to have specific prospective projects: multi-centre, involving the leaders in the field. We must lead in the establishment of medical guidelines in our area of expertise as we have the key opinion leaders in our Section. I would also like to see ESGURS publish certain standards of care. The current surgical masterclasses all over Europe need to be identified and coordinated through ESGURS. We could establish certificates of competence for certain operations or conditions. The section needs to become more democratic, its bylaws revisited and members having more of a

say. Finally, I believe that the industry should be encouraged to participate in our activities. Do you have any words for the ESGURS section (and the readers of European Urology Today) on the occasion of you taking over from Dr. Djinovic? Dr. Djinovic has served us proudly! Our meetings have grown significantly under his leadership. We’ve enjoyed very high attendance figures at our section meetings held during the EAU Annual Congress. Rados has always been fair and let all players have a chance to promote new ideas and exciting research. We thank him for his and wish him well for the future.

ESU’s educational aspirations for urologists grow Objectives, current activities and the benefits against burnout Dr. Joan Palou ESU Chairman Fundació Puigvert Barcelona (ES)

jpalou@ fundacio-puigvert.es Good urological education stems from purposeful guidance of highly-experienced experts. It is also the product of accumulated reliable, evidence-based information. And we at the European School of Urology (ESU) aim in bolstering patient care and daily clinical practice. As American lawyer and civil rights activist, Marian Wright Edelman, once said “Education is improving the lives of others and for leaving your community and world better than you found it.”

Participant hones her laparoscopic skills at a programme in Singapore

For two decades now, the ESU has been fully committed to offer prime training to young and experienced urologists. We develop and refine our educational activities to parallel the expanding field of urology. We tailor these activities to provide urologists diverse learning possibilities and to meet their professional needs. Being a urologist is an amalgamation of two specialties: the medical aspect (requiring knowledge on metabolism, stones, infections, endocrine pathways in infertility, and medical oncological treatments to name a few) and the surgical aspect. We aim for complete coverage of these aspects (in a urological sense), and more innovative formats for our educational activities. Our other objective is designing a Pan-European postgraduate education consisting of unbiased, high-quality curriculum provided by European and non-European experts. What we do now Our ESU courses and Hands-on Training courses are integrated into the scientific programmes of international events and EAU’s own meetings and congresses. For immersion into specific topics, we offer masterclasses that include live and/or semi-live surgeries with updates from renowned field experts. To expand the capabilities of young, promising urologists, we established the new URO Berlin Skills Teaching and Training (UROBESTT) which recently took place in February. And we also encourage urological residents who are in their final year to participate at our European Urology Residents Education Programme (EUREP). Since EUREP’s inception in 2003, about 5,700 delegates from 44 countries in and beyond Europe have participated in this highly-acclaimed programme. To give urologists from all over the world access to reliable resources online, we also offer webinars to address current treatments and controversies in various urological subspecialties, and e-courses to provide current updates.

What is STEPS? STEPS, or “Sessions To Evaluate ProgresS in the management of urological cancers”, is a programme specifically designed for recently specialised onco-urologists who want to learn directly from worldleading experts in bladder, prostate, renal and testis cancers. The CME-accredited programme is a fundamental part of the EAU/ESOU strategic partnership with Ipsen. It is founded on our shared commitment to the education of young urologists. Bringing together a multinational group of medical professionals across several areas of expertise, and with different experiences, allows the fellows to see a variety of new treatment possibilities. It can highlight the pitfalls and solutions provided by diverse approaches. It also opens the door to creating international ties among medical practitioners, and a networking opportunity that can prove invaluable to the careers of young clinicians. “STEPS connects younger urologists from different countries – it’s very interactive with lots of new information and data discussed” STEPS fellow 2018

To date, 20 different internationally recognised experts, supported by the ESOU Board, have inspired 158 fellows from 30 countries – and our objective is to continue supporting STEPS to help improve the management of all patients with urological cancers. Who should apply? Recently specialised clinicians with a firm interest in the management of urological cancers, who: - Can demonstrate support from their Head of Department

Molecular aspects of bladder cancer in the young patient immunohistochemistry

How genomic alterations are particularly of relevance for younger bladder cancer patients Prof. Roland Seiler Dept. of Urology University Hospital Bern (CH)

Development of high-throughput technologies, such as next generation, sanger sequencing or microarrays, have permitted investigation of the molecular landscapes underpinning human malignancy. In recent years, a range of groups and consortia, including ‘The Cancer Genome Atlas’ (TCGA), have leveraged these techniques and exerted tremendous effort to study large cohorts of patients with bladder cancer. The resulting molecular characterisations have provided important insights into recurrent genomic and transcriptomic alterations present in bladder cancer and dramatically improved our understanding of disease biology. We now have at our fingertips a vast array of multimodal data representing the epigenetic, genomic, transcriptomic and proteomic features of bladder cancer. These data levels give insight into different biological aspects and allow to answer different scientifical questions. Methods for analysis and interpretation may be different depending on the scientific purpose. These differences in interpretation and analysis might be of particular relevance to young patients. Bladder cancer is strongly related to age and is therefore a typical disease of the elderly. Indeed, the average age at diagnosis is approximately 73 years. However, almost all large cohorts include patients below the age of 50 or 40 years. Urothelial bladder cancer in childhood is extremely rare but has been described in rare cases as young as 10 years old. While the above mentioned efforts have been undertaken to improve the understanding of the biology of bladder cancer in general, particularly in young patients, investigations should include other aspects as well. The following paragraphs will describe molecular aspects of bladder cancer in the young patients. Genomic alterations are described first, because they may be most relevant in this particular context.

“...genetic counselling should be considered in patients with bladder cancer below the age of 50 years.” Classification and impact of genomic alterations in cancer Permanent alterations in DNA are termed mutations and in cancer there are two broad categories: germline versus somatic mutations. Germline mutations are present in germ cells and can be transmitted to descendants. Some germline mutations are linked to cancer predisposition. The most famous example is Angelina Jolie, who carries a germline mutation in a gene called BRCA1. This gene helps coordinate DNA damage repair: an important mechanism for maintaining DNA integrity throughout life. Germline mutations in BRCA1 are strongly associated with the development of breast cancer, and presumably contributed to Angelina Jolie’s decision to undergo preventive bilateral mastectomy. In contrast, somatic mutations are mutations that are acquired during cancer development and evolution. Therefore, somatic mutations are not present in germ and non-cancerous cells. To acknowledge and resolve these two categories of mutation, good scientific practice for genomic DNA sequencing in cancer research typically includes two specimens for analysis: cancerous tissue as well as non-malignant tissue. The latter aids considerably in so-called ‘normalisation’ of the individual cancer tissue genome but also ensures more accurate characterisation of somatic mutations. The spectrum of somatic mutations can then be used to describe the evolution, molecular subtype and potential therapeutic vulnerabilities in the given tumour. Genomic alterations of bladder cancer in the young patient In the context of a young bladder cancer patient, early data suggest some somatic mutations are less common (e.g. mutations in TP53 and RB1) while 20

others seem to be more prevalent (e.g. HRAS). However, this concerns unpublished data obtained from the bladder cancer TCGA database, which included only 8 patients below the age of 45 years.

Figure 1

In daily clinical practice, one observes clustering of bladder cancer in families. However, one of the main risk factors of bladder cancer is exposure to carcinogens. Therefore, clustering of bladder cancer in families may mainly be related to similar environmental exposures. Hereditary bladder cancer is rare but has not yet been investigated in detail. One can hypothesise that some germline mutations may also have caused bladder cancer in the few described young patients. However, there is only scarce knowledge and the published data has caveats: the researcher used targeted sequencing, only focusing on a handful of genes. This approach may not allow a non-biased discovery of germline mutations that are Figure 1 associated with bladder cancer. Furthermore, this aspect has neither been investigated in the context of young patients nor in the context of ethnic backgrounds and races. In parallel to findings from e.g. breast cancer, it may not be surprising that the few reports also described the presence of germline mutations in the DNA damage repair pathway in bladder cancer patients. A more comprehensive analysis of germline mutations in bladder cancer is needed to understand their role in the development of bladder cancer. These investigations need to focus on associations of germline mutations and bladder cancer. On the other hand, as seen in other hereditary cancers, they need to investigate if the gene with a known germline mutation is affected by a second somatic mutation that may potentiate its cancer driving impact. Transcriptomic alterations in bladder cancer and young patients The understanding of transcriptomics in bladder cancer was dramatically improved by the discovery of molecular subtypes. Based on gene expression or transcriptomics, bladder cancers can be clustered into different groups, so called molecular subtypes. Different subtyping methods have been described that became more and more confusing for non-specialists. Groups that are involved in molecular subtyping undertook a great effort and consensus was reached on 6 molecular subtypes. Interestingly, when comparing these subtypes and patient age, it is noticeable that all bladder cancers of patients below 43 years showed a Luminal papillary subtype (see Figure 1). However, again the bladder cancer TCGA dataset was not designed to investigate transcriptomics in young bladder cancer patients and more comprehensive characterisation is needed. Recommendations for clinical practice There are currently no guidelines and recommendations for genetic counselling in bladder cancer. This is likely because of the lack of evidence, the fact that it often arises in older patients and is mainly related to exposure to carcinogens. However, until more evidence is available, it may be reasonable to follow recommendations from other cancer types. Referral to genetic counselling should be considered in patients with: •

to develop colorectal, endometrial, ovarian and gastric cancer. Screening of these organ systems should be considered too. Genetic counselling When referring a patient for genetic counselling, one should be aware of potential consequences. Due to the fact that germline mutations can be transmitted to descendants and be present in several other family members, detection of such a germline mutation in the referred patient may also affect his/her family members. Importantly, in cancer types with known hereditary components (e.g. breast cancer), the lack of detection of such a germline mutation does not reduce the risk for relatives of the patient conferred by a family history of cancer. These issues should be discussed with the patient prior to referral. Early data seem to show that germline mutations in DNA damage and mismatch repair are associated with bladder cancer. However, one can neither recommend a specific follow-up

schedule including cystoscopies or cytology nor surgical procedures such as cystectomy based on the current evidence. Take home messages: In patients with bladder cancer below the age of 50 years consider: •

In this recommendation, bladder cancer is not listed but could be taken into account.

Urothelial carcinoma of the upper urinary tract is more frequent in patients with Lynch syndrome that is caused by mutations in mismatch repair genes (MLH1, MSH2, MSH6 or PMS2). Therefore, it is can be considered to search for defects in mismatch repair in patients with urothelial carcinoma of the upper urinary tract. In bladder cancer patients below the age of 50 years, it seems to be reasonable to screen for Lynch syndrome as well. It can be diagnosed by DNA sequencing or by immunohistochemistry for MLH1, MSH2, MSH6 and PMS2. The expression of at least one of these four proteins is absent in 83% of tumours from patients with Lynch syndrome. Finally, patients with Lynch syndrome have an increased risk

Urolithiasis as a systemic disorder: What are the hypotheses? New pathogenic mechanism ‘endothelial cell hypothesis’ in calcium oxalate stone disease Prof. Kemal Sarica Chairman of EULIS Dept. of Urology Kafkas University Kars (TR)

The pathophysiological mechanisms of calcium oxalate stone formation are still to be elucidated. Published data so far showed that elevated urinary oxalate levels on one hand will induce renal tubular cell toxicity where a pre-existing renal epithelial cell injury preferably in proximal part of the tubes is essential for crystal attachment. On the other hand hyperoxaluria may cause crystal formation and deposition in the presence of injured renal tubular epithelium1-3. Although supersaturation is the main driving force for crystallisation, some basic research studies have also clearly pointed out that hyperoxaluria and subsequent crystal formation are not the sole prerequisites for this process. Although some investigators reported that oxalate and/or CaOx crystals have direct toxic effects on renal tubular cells, others suggested the crystal–cell interaction process as the crucial mechanism for renal tubular epithelial cell injury which is thought to be mediated by increased free radical production2-9. Vascular factors Although crystal-cell interaction was found to be responsible for tubular injury related crystal deposition, vascular factors have gained more importance in the formation of renal stones in recent years. The least popular one of these is intravascular phenomenon as proposed by Low and Stoller3. They proposed that stones form within the vasa recta of renal papillae. Injury to vasculature results in atherosclerotic-like lesions and the eventual calcification erodes the papillary duct and serves as a nidus. Although subsequent studies could not verify them10, in our recently published original study we were able to show that the renal epithelial cell injury is also under the control of vascular endothelial cells. Our results partly support this hypothesis where the correct order of events might be oxalate elevation in intravascular area, resulting in endothelial dysfunction first and eventually renal epithelial cell injury and death upon which facilitated crystal attachment occurs. Endothelial cell hypothesis In relation to this hypothesis we were able to show that hyperoxaluria induces asymmetrical dimethyl arginine (ADMA) expression which is a marker of endothelial dysfunction in renal tissue of ethylene glycol administered rats11. To support our hypothesis further, in another, later study we aimed to demonstrate this critical interaction between renal vascular endothelial (HUVEC) and renal tubular epithelial cells (RPTEC) in a direct manner by using co-cell culture system. Our data have clearly shown the decreased renal tubular cell viability after co-incubation of RPTECs with HUVECs and pretreatment with PDTC which antagonises ADMA and prevented the formation and extent of renal tubular cell death with restoration of endothelial cell function12. These findings did further confirm the results of our first study which focused on the ‘interaction between renal vascular endothelial and tubular epithelial cells’ resulting in renal tubular cell injury originating from endothelial cell dysfunction. Both of our studies put forward a new understanding, ‘endothelial cell hypothesis’ in stone formation. These findings were also partly supported by other authors. Ilbey and his co-workers13 showed that administration of PDTC to hyperoxaluria induced rats prevented crystallisation in renal tubules by decreasing oxidative stress in renal tissue. Although they claimed the findings to be the result of direct action of PDTC on renal tubular oxidant stress, their findings are actually in parallel with and supportive to our study mentioned above. In this study again, the authors did not demonstrate tubular cell death, although they attributed the protective role of PDTC to the prevention of hyperoxaluria-induced peroxidative damage to renal tubular cells. Related to their findings, induction of renal tissue iNOS expression is supposed to be by p38-MAPK whose expression was increased with ethylene glycol administration. Since p38-MAPK activity was shown Saturday, 16 March 2019

to be stimulated by vascular endothelial growth factor receptor-2 activation14 and vascular endothelial growth factor gene polymorphism has been found to be associated with calcium oxalate stone disease15, it can be postulated here that ethylene glycol-induced elevation of plasma oxalate levels initially affects the vascular endothelium and activates VEGF which eventually induces p38-MAPK and then iNOS expression and causes NO production. Similar data were reported by Huang et al.16: excessive CaOx crystal accumulation was shown to enhance endothelial NOS (eNOS), iNOS, and NAD(P)H oxidase protein expression in the kidney. Increased superoxide formation was thought to be derived from NAD(P)H oxidase and uncoupled eNOS, and increased nitrotyrosine formation from iNOS and ED1-positive cells that gathered around the CaOx crystals. Co-treatment with L-NAME reduced renal oxidative nitrosative stress and tubular damage. Renal tubular cell death This study again confirms that CaOx stone formation is a cumulative result of endothelial dysfunction. It states that increased ROS production was a result of NAD(P)H oxidase activation by calcium oxalate crystals and resulting eNOS uncoupling further amplifies oxidative stress in kidneys. The results of our study mentioned above are in accordance with these findings and prove that hyperoxaluria-induced endothelial cell dysfunction plays a crucial role in renal tubular cell death. Endothelial cells not only play role in pathological processes, but also regulate some physiological mechanisms. Proximal tubule epithelial cells are in close contact with the renal capillaries. Vascular endothelial cells have been shown to regulate proximal tubule epithelial cell function especially sodium transport through NOS-dependent upregulation of cGMP in these cells17. Additionally, the endothelium of the peritubular capillaries have been shown to affect proximal tubule acidification, probably via stimulation of Na?/H? exchanger and endothelium- derived nitric oxide (EDNO) which has been thought to play important role in this function18. Confirmatory results were reported by Wang et al.19 who found that nitric oxide regulates HCO3- and Na? transport by a cGMP-mediated mechanism in the kidney proximal tubule. Based on all these demonstrated facts we may claim that if physiological transport mechanisms are under the control of vascular endothelial cells, any pathological condition affecting endothelial function should have direct effects on renal tubule function. The above-mentioned hyperoxaluria-induced changes in our published study do further support this critical relationship. Urolithiasis and systemic disorders The possible association of urolithiasis with certain systemic disorders such as obesity, hypertension, hyperlipidaemia and metabolic syndrome (all of which are characterised by systemic endothelial dysfunction)20-25 does further support our ‘endothelial cell dysfunction’ theory in the formation of renal stones from the ‘clinical’ point of view. Most of these studies demonstrate increased ROS in these conditions. Disturbed endothelial function is supposed to be the result of oxidative stress induced by high lipids, blood pressure or glucose. In our previously published study, we have shown that hyperoxaluria causes systemic endothelial dysfunction as ADMA levels were found to be increased in hyperoxaluric rats11. Since hyperoxaluria is the result of excess oxalate in the blood stream, an initial event could be systemic endothelial dysfunction in this cascade. All of these studies indicate that urolithiasis is not a disease restricted only to the kidneys but is part of a systemic disorder or may be a separate syndrome. Oxalate-induced death of renal tubular epithelial cells exhibits predominantly the features of apoptosis26. Oxalate-induced free radical production is the offender of this process. Increase in the rate of apoptosis with co-incubation of RPTECs with HUVECs indicates that apoptosis of renal tubular epithelial cells could be mediated by endothelial cells. As mentioned above again, our previously published data clearly showed that pretreatment with PDTC will preserve endothelial cell function and prevent tubular apoptotic changes indicating the possible direct role of endothelial cells in stone formation.

‘endothelial cell hypothesis’ in CaOx stone formation. The findings which may be obtained with this project will help understand ‘systemic underlying causes of calcium oxalate stone disease’ better and result in treatment strategies that target endothelial cell preservation which may help in the prevention and/or management of stone disease.

Anniversary 20th EAUN Meeting Strong international bonds highlighted in Joint Sessions with AEEU, ECET and ANZUNS Corinne Tillier Chair EAUN Scientific Congress Office Amsterdam (NL)

c.tillier@eaun.org Some of the readers may remember the first urology nurses conference in Brussels, Belgium, where around 68 nurses joined in session room Cinedoc, April 2000. Despite some problems with the projectors on the second day, this first meeting was such a success that it was decided to continue this initiative in the next year and form a group of organisers.

Rita Willener presenting in Stockholm in 2009

At the request of Ronny Pieters, on 7 September 2000 a meeting was organised by the EAU to discuss the start of a nurses’ committee. Ronny Pieters (BE), Martin Beynon (UK), Maria Ascension Crespo Garcia (ES), Rita Willener (CH), Thea De Laat (NL) attended, as well as two professors from Switzerland, Prof. Fiona Burkhard (CH) and Prof. Hans-Jürg Leisinger (CH), and the Secretary General and founder of the EAU, Prof. Frans Debruyne, as well as EAU Executive Manager Operational Affairs Jacqueline Roelofswaard.

proposed a programme on Testicular and Prostate cancer, Cystoscopy and Nurses training in various countries. At the third meeting in February in Birmingham in 2002, nurse participants from all over Europe got to know each other better at the ‘Healthcare Professionals Dance Evening’ in Tiger Tiger, the same party destination that was unknowingly selected by the EAUN Board 15 years later in London! Ronny Pieters chaired the EAUN until 2004, when Aase Grundal (DK) took over (she chaired from 2004-2006). After a short co-chairmanship by Ronny Pieters and Jerome Marley until 2007, the following chairs were installed at the annual meeting: Bente Thoft Jensen (DK, 2007-2011), Kate Fitzpatrick (IE, 2011-2014), Lawrence Drudge-Coates (UK, 2014-2016) Stefano Terzoni (IT, 2016-2018). The current chair is Susanne Vahr Lauridsen (DK, 2018-2020), who will hand over the baton to Paula Allchorne (UK) to chair the EAUN from 2020 until 2022.

The committee that decided to initiate an annual meeting for urology nurses in Brussels in April 2000

At the conference in March 2005 the very first EAUN guidelines were introduced, entitled “Urethral Catheterization, Section 1: Male Catheterization”, of what now is a series of 11 guidelines. The first Nurses Panel consisted of Martin Beynon (UK), Thea De Laat (NL), Jessica Greenwood (UK), Toine Van Opstal (NL), Eva Lindblom (SE) and Eija Luotonen Emblem (NO). Many other important guidelines for urology nurses followed, continuously keeping up with the developments in the scientific process of developing guidelines. The series currently counts 7 topics which are regularly reviewed. In 2014 the EAUN Board decided that the important task of composing the Scientific Programme of the annual EAUN meeting should be left to a committee of experienced scientifically trained nurses, which would enable the board to increase their efforts to develop educational activities and accreditation specifically for the members and build on the international relations.

16-18 March 2019, Barcelona Looking back it cannot be missed that there is one person who has been at the heart of all these developments. This, and the joyous occasion of celebrating the 20th annual meeting here in Barcelona, is the reason the EAUN Board has established a lifetime achievement award to be awarded yearly to an exceptional EAUN member. The award is named after its initiator: Mr. Ronny Pieters (BE). The award will be handed over for the first time at the Plenary Opening Session this morning at 9.00 AM. Don’t miss it!

The landscape of urogenital cancer treatment is constantly developing through the generation of new clinical data. This symposium will take a journey from the past through to the present with a view of what the near future holds for prostate, renal and bladder cancers.

and immunotherapies, and how this could potentially improve patient outcomes. Recent data is investigating how patient characteristics can impact a physician’s approach to treatment sequencing and selection.

Treatments for prostate cancer have continually evolved to improve patient outcomes. Lately, there has been clinical interest in systemic therapies, using androgen deprivation therapies (ADT) as a backbone for combination therapies in the management of patients with prostate cancer.

Finally, clinical evidence from trials using blue-light flexible cystoscopy (BLFC) have demonstrated the consistent performance of photodynamic diagnosis in the outpatient setting and its positive impact on the patient experience. The main challenge now is how this technique can be integrated into urological services across Europe.

For advanced renal cell carcinoma (aRCC), there is a growing body of evidence exploring the use of a combined treatment approach with tyrosine kinase inhibitors (TKIs)

The faculty welcome you to join them for this engaging and insightful symposium navigating the landscape of urogenital cancer treatment.

Innovative surgical procedures in functional urology Are synthetic slings for female stress urinary incontinence coming to an end? David Castro Díaz Department of Urology. Hospital Universitario de Canarias. Universidad de La Laguna (ES)

Surgical management of female stress urinary incontinence (SUI) has evolved within the last two decades implementing synthetic mid-urethral slings (MUS) which became the standard procedure. In fact, MUS have replaced the traditional Burch colposuspension and the autologous fascia sling, becoming the most commonly used procedure for the management of SUI around the world. In the search for a better outcome and simplicity, many techniques were initially adopted to be later abandoned because of either safety or efficacy issues. Moreover, few devices were introduced into the market to be later also abandoned due to poor long-term durability as well as complications1. Just to mention a few, we might recall the Kelly plication or anterior repair approach, the Marshall-Marchetti Krantz procedure, also known as cystourethropexy, several needle suspensions techniques, Raz’s procedures, the UroVive self-detachable balloon system, the Vesica percutaneous bladder neck stabilization, the bone anchoring AMS, the in-fast™ minimally invasive pubovaginal sling, the AMS Mainstay for bone anchoring, etc. Consequently, Burch colposuspension and autologous facial sling became the most commonly used procedures for the management of stress urinary incontinence until the introduction of synthetic MUS.

“Although colposuspension is related with later development of prolapse, it has been associated with high rates of objective and subjective long-term cure.” Cure rates and morbidity Although colposuspension is related with later development of prolapse, of either middle or posterior compartment2, it has been associated with high rates of objective and subjective long-term cure. Studies have shown that after 5 years, 70% of women continued dry3. Laparoscopic colposuspension is associated with similar cure rate of SUI, when performed in the same manner but with a lower risk of complication and shorter hospital stay4. The autologous fascial sling has been considered as to provide a similar cure rate of SUI, when compared with colposuspension but with a higher risk of post-operative complications, particularly bladder outlet obstruction, need for self-catheterization, etc.5,6. In recent years a modification of the traditional pubovaginal, a shorter sling (sling on a string), has been used based on a needle suspension technique in a more minimally invasive manner, placed loosely at the mid-urethra, although long term outcome data are needed in order to widely adopt this technique7. However, in a direct comparison of autologous fascial sling with colposuspension, in a controlled randomised trial, the autologous fascial sling showed a significantly higher cure rate but with higher morbidity, including urgency incontinence, voiding dysfunction and urinary tract infections8. Improved management of SUI The introduction of the tension-free vaginal tape (TVT) in 1998, transfigured the management of SUI worldwide. The main reason for this change was that TVT demonstrated to be an efficacious and minimally invasive procedure, that could even be carried out under an outpatient basis causing less postoperative pain and morbidity. This success stimulated the development and manufacturing of many similar commercial slings. Complications were mostly related to inexperienced and incorrect trocar positioning and placement of the tape causing serious injury to the bladder, bowel or vessels warranting the need of intraoperative cystoscopy. In order to reduce the risk of a retropubic pass of the trocar, the need of cystoscopy and to simplify the procedure, a trans-obturator approach (TOT) to Saturday, 16 March 2019

implant a MUS was introduced later becoming very commonly used9,10. As it is a minimally invasive procedure it can also be performed on outpatient or day case surgery. Several studies have demonstrated its efficacy and a very low rate of complications. When comparing TOT this with the retropubic TVT, both techniques show similar efficacy and safety11. Moreover, several systematic reviews and metaanalysis of randomised controlled trials have shown comparable or even higher cure rate for a synthetic mid-urethral sling, when compared with colposuspension. In addition, the operative time is shorter, and the rate of voiding dysfunction is lower with MUS when compared with colposuspension12. The raise of mid-urethral tapes As a consequence of the benefits of MUS, when compared with colposuspension and autologous fascial slings, mid-urethral tapes became the procedure of choice for the management of female stress urinary incontinence worldwide. Due to the success of mid-urethral synthetic slings, the use of mesh implants was extended to the management of pelvic organ prolapse (POP) and implemented in daily practice. The rational basis for this approach was that traditional POP surgery had a high recurrence rate, which could be lowered using a synthetic transvaginal mesh (TVM). However, due to the high complication rate of POP meshes, patient complains and legal issues become very common. On the other hand, in a multicentre randomised controlled trial, comparing traditional repair versus synthetic mesh and biological grafts in more than one thousand women, with two years follow-up, it was observed that neither synthetic or biological TVM provided any additional benefit over traditional native tissues POP repair. Furthermore, although there were no differences regarding serious adverse events, dyspareunia or recurrences, one in eight of women in the synthetic mesh group needed to undergo reoperations for management of mesh complications13. The FAD released safety communications on the use of TVM and significant development in regulations, medico-legal issues and statements from scientific societies warned of the actual risk of using meshes for POP repair. As a consequence of a growing number of legal claims, some companies manufacturing synthetic meshes decided to withdraw their products from the market. Although most legal claims involved synthetic slings for SUI, social and patients concern started after the FDA communication on TVM for POP. Nevertheless, several systematic reviews, evaluating efficacy, complications and re-intervention rates of MUS, have demonstrated similar or even higher objective cure rate of MUS when compared with colposuspension. Furthermore, MUS are associated with shorter operating time, less postoperative de novo voiding issues or overactive bladder symptoms (14). Although MUS were initially implemented without enough evidence, this procedure is clearly the most extensively investigated technique for surgical management of SUI in women. Moreover, MUS offer a good safety profile, as concluded in a recent Cochrane review14. The social, legal and economic impact of all of these controversies have led authorities to ban the use of implant mesh in several countries in order to prevent patients from possible damage of synthetic materials for SUI and POP. As a result, physicians

and scientific societies raised concern because such constraint will prevent women from having the current best surgical option for the management for SUI. Scientific societies elaborated guidelines for the indications of its use in patients with POP, limiting the use of meshes only to complex cases with recurrent prolapse in specialist referral centres15. Differences from synthetic meshes for POP and SUI were highlighted as there are clear differences particularly regarding surface extension which is obviously smaller for midurethral tapes and larger for TVM. Recommendations for mesh implants Because the safety of mesh implants has been brought into question by thousands of women around the world, mesh implants have been banned in several countries including Australia, New Zeeland and the UK. The National Institute of Clinical Excellence (NICE) recommends the use of surgical mesh for SUI or POP only after all other surgical options have failed. NICE also recommends “the use of mesh implants for stress urinary incontinence only as last resort”. NICE suggested that “suspension of the use of mesh in England should remain in place until the national database for registering operations and complications was up and running and when all operations could be performed by specialist surgeons based at specialist treatment centres”16.

“The EAU guidelines continue recommending MUS and other procedures highlighting the need to properly inform patients on possible side effects and complications.” NICE also warns on the need to properly inform women undergoing surgery for SUI or POP, of possible risk and benefits of the procedure. A close follow-up of patients was also suggested. Some authorities have recommended that mesh should be just a third line option therapy and be offered only after medical and other surgeries failed. While most of us would agree on this statement regarding POP, it is clear that most of the surgeons involved in the management of SUI, would recommend the use of mid-urethral synthetic slings because of its efficacy, safety and simplicity when compared with Burch colposuspension or autologous sling. Nevertheless, as the long-term outcome is not completely known, database and national registries should be implemented and to achieve this it is clearly needed the support from authorities as our main aim is to obtain the best benefit for our patients. A recent join consensus group by the European Association of Urology and the European Urogynaecology Association concluded that “When considering surgery for SUI, it is essential to evaluate the available options, which may include synthetic mid-urethral slings (MUSs) using PP tapes, bulking agents, colposuspension, and autologous sling surgery. The use of synthetic MUSs for surgical treatment of SUI in both male and female patients has good efficacy and acceptable morbidity. Synthetic mesh for POP should be used only in complex cases with recurrent prolapse in the same compartment and restricted to those surgeons with

appropriate training who are working in multidisciplinary referral centres”15. Furthermore, the EAU guidelines continue recommending MUS and other procedures highlighting the need to properly inform patients on possible side effects and complications17. The banning of MUS would change the current practice for the management of SUI in such a way that would compel surgeons to use old techniques, that have been proved to have less efficacy and safety, and sufferers would be prevented from receiving the best evidence base surgical management. Consequently, synthetic slings for the management of stress urinary incontinence have not come to an end, but as a consequence of the media and social impact, this controversy may possibly change our current practice as many patients might be reluctant to undergo a synthetic sling placement for the management of this bothersome and costly condition.

Perioperative systemic immunotherapy Where are we heading in muscle invasive bladder cancer? Test new therapies Radical cystectomy in Europe usually occurs 6 to 8 weeks after MIBC diagnosis, and this time frame offers a unique opportunity to test new therapies preoperatively. Pathological downstaging to non– muscle-invasive disease or pathological complete response (pT0) to neoadjuvant chemotherapy is a well-recognised biomarker of improved overall survival (OS) and can be offered as a suitable endpoint for phase II neoadjuvant trials12,13.

Dr. Andrea Necchi Dept. of Medical Oncology Milan (IT)

The PURE-01 study was designed to obtain biomarker results and assess the efficacy of single-agent pembrolizumab in patients with MIBC, regardless of cisplatin eligibility14. In this study, patients with T2-3bN0M0 MIBC received three courses of 200 mg pembrolizumab every 3 weeks, preceding radical cystectomy. Pembrolizumab exhibited a 42% pT0 among 50 treated patients and was safely administered. Immune-related adverse events have been reported, but they did not delay the planned surgery and postsurgical complications were similar to those reported in the most recent literature related to either open or robot-assisted procedures.

After decades of therapeutic stagnation in the field of urothelial carcinoma (UC), the introduction of new agents targeting the PD-1 and PD-L1 axis has revolutionised the way we currently manage locally advanced or metastatic UC1-6. These improvements have meant a significant shift in the way we conceive the treatment of early stage bladder UC thus far. The evolving standard of care Based on their documented activity in UC, coupled with the optimal toxicity profile, immune checkpoint inhibitors yield the best features for use in earlier disease stages (e.g. muscle-invasive bladder cancer (MIBC) in nonmetastatic UC). By recapitulating the therapeutic model proposed for early-stage non– small cell lung cancer or melanoma7,8, integrating short courses of immunotherapy before radical cystectomy in MIBC is poised to make a significant impact in MIBC management. In fact, although the recommended standard of care for MIBC in patients who are eligible to receive cisplatin is neoadjuvant chemotherapy followed by radical cystectomy, the real-world adherence to this standard therapy is poor, with less than 25% of patients ultimately accessing multimodality treatment9. Additionally, about 50% of the total amount of patients with UC are considered ineligible to receive cisplatin based on their renal function, performance status and comorbidities, and a subset of patients refuse to receive any chemotherapy10. And although neoadjuvant chemotherapy is active, residual high-risk disease (i.e. pT2 or higher) is still present in more than 50% of patients and represents a poor prognostic factor11. Finally, for the patients who cannot receive cisplatin, there is no standard neoadjuvant therapy.

Finally, the preliminary findings of a phase 1b/2 trial of pembrolizumab plus gemcitabine and cisplatin showed an encouraging pathologic downstaging proportion of approximately 60%17.

Current challenges However, several important issues necessitate additional data to confirm such a therapeutic strategy as the new standard. Firstly, the patient selection still needs to be optimised. Whether cisplatin eligibility is needed to select patients for new neoadjuvant therapies is a question of In particular, no differences in terms of intra-, perinoteworthy importance, and it is linked to the role and postoperative complications were recorded of PD-L1 expression. Although the PURE-01 study compared with patients from the same centre demonstrated that the strategy of treating all undergoing radical cystectomy and not receiving patients is feasible, it should be noted that, among pembrolizumab. Similarly, intraoperative performance patients with advanced UC, the safety alert on (e.g. number of removed lymph nodes, soft tissue decreased survival with pembrolizumab and surgical margins and operating time) was not atezolizumab in patients who are eligible to receive compromised by neoadjuvant immunotherapy. cisplatin with low PD-L1 expression from Notably, PD-L1 expression (defined as combined IMvigor130 and KEYNOTE-361 studies resulted in an positive score ≥ 10% with the 22C3 antibody) and FDA update of drug labels. Therefore, caution is high tumour mutational burden (TMB; assessed with needed when avoiding standard cisplatin-based the FoundationOne assay) predicted for enriched chemotherapy, and thorough patient information is pathologic responses. necessary prior to including patients in such trials. A summary of the ongoing neoadjuvant PURE-01 trial immunotherapy trials, including key information on At last year’s Annual EAU Congress, updated patient selection, is provided in Table 1. results from the PURE-01 trial have been presented, including the preliminary analysis of Secondly, long-term follow-up is lacking in most survival. Of note, pembrolizumab confirmed to be immunotherapy trials and, most importantly, no effective both in terms of relapse-free survival data so far indicate RFS and OS improvement in the (RFS) and overall survival (OS), also in those postoperative setting among patients who received patients who did not respond at the pathologic neoadjuvant immunotherapy. Most noteworthy, the level15. value of pathological response after neoadjuvant single-agent checkpoint inhibitors is unknown.

Table 1: Summary of the clinical trials of neoadjuvant immunotherapy recruiting patients with muscleinvasive bladder cancer Single-Agent Therapy

The results of another window-of-opportunity trial have been presented, allowing for the administration of two courses of neoadjuvant atezolizumab in patients with cisplatin-ineligible MIBC. In this study, a pT0 was observed in 40% of patients with PD-L1–positive disease (evaluated on tumour microenvironment with the anti–PD-L1 antibody SP142) compared with only 16% in the PD-L1–negative cohort16. In both investigatorinitiated neoadjuvant trials, treatment produced major pathologic responses indicating that the side effects of chemotherapy can be reliably avoided when using single-agent immunotherapy.

Role of biomarkers These limitations highlight the role of the biomarkers associated with enriched pathologic responses. Besides the value of PD-L1 expression, analyses of matched pre- and post-therapy tumour samples in the PURE-01 and ABACUS studies revealed that strong immune-mediated mechanisms of adaptive resistance may develop during neoadjuvant immunotherapy administration and may contribute to the lack of tumour regression from radical cystectomy, despite a concurrent promotion of adaptive immunity. In addition, TMB emerged as potentially the biomarker most robustly associated with the activity of pembrolizumab.

Interestingly, some of the biomarkers predictive for neoadjuvant chemotherapy activity are also reported with neoadjuvant immunotherapy use. DNA damage response and repair (DDR) gene alterations, for example, have been associated with both dose-dense neoadjuvant gemcitabine/cisplatin and methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC) chemotherapy, although they emerged as a surrogate of TMB in the PURE-01 study17,18. Similarly, the basal phenotype of The Cancer Genome Atlas classification was linked to the greatest benefit achieved with neoadjuvant chemotherapy, and its immune infiltrate features also portend response probabilities with checkpoint inhibitor use19. All these premises warrant confirmatory studies with a randomised design. The potential of combination immunotherapy Of note, the dynamic expression of several negative regulators of the immune response from the PURE-01 study also suggests that combination immunotherapeutic approaches may further enhance the pathological response. Also, the few ‘drugable’ gene alterations that were lost or newly identified in cystectomy specimens support the need for reassessing post-immunotherapy tissue before screening the patients for trials with targeted agents. Among the new drug combination strategies, emerging data point at the potential of poorer response to anti–PD-L1 therapy in patients with FGFR aberration–positive disease. The response to checkpoint inhibitors is largely dependent on an existing antitumour T-cell response, including sufficient T-cell infiltration in the tumour microenvironment. However, not all UC exhibits high T-cell infiltration. Similarly, differential responses to immunotherapies have been observed in UC based on bladder cancer molecular subtype and the underlying immune landscape of these subtypes. Luminal 1 tumours are reported to be enriched for FGFR3 mutations and lacking in immune marker expression and immune cell infiltrate20. The luminal 1 subtype showed the lowest response rate to the anti–PD-L1 inhibitors atezolizumab and nivolumab compared with other bladder cancer subtypes2,21. Therefore, combination strategies of immune checkpoint inhibitors with agents targeting FGFR alterations yield the potential to overcome the limitations of PD-L1 expression, and clinical trials are planned in the neoadjuvant setting. Optimising clinical trial design Looking at the possible developments of clinical trials in MIBC, there is an ongoing debate regarding the identification of the optimal trial design for studies aimed at confirming the role of neoadjuvant immune checkpoint inhibitors and setting new standards. Such a natural evolution would imply the comparison of standard chemotherapy plus immunotherapy with chemotherapy alone in a 1:1 randomised design. Pending the results of large phase III trials that are recruiting patients in first-line metastatic setting (IMvigor130, KEYNOTE-361, and CheckMate 901), mature results with neoadjuvant combination chemo-immunotherapy in MIBC are pending.

Chemotherapy combination strategy Yet there are some perplexities in pursuing the chemotherapy combination strategy: platinum-based combinations do not address the chemotherapyineligible population or those who refuse to receive any chemotherapy preoperatively, pushing clinicians to the old limitations of chemotherapy delivery in these patients. Also, adding chemotherapy may substantially prolong the total duration of neoadjuvant therapy compared with the short courses that were allowed with single-agent immunotherapy. The postoperative phase of these studies is still under debate, as the optimal use of adjuvant checkpoint inhibitors based on the quality of pathologic response in largely unknown. Finally, the optimal trade-off between the optimal therapeutic regimen and use of PD-L1 biomarker is still unaccounted for. In the PURE-01 study, among the patients who expressed PD-L1 the pathologic downstaging rate was 65.7%, higher than the 60.0% achieved by adding standard chemotherapy to pembrolizumab, although heterogeneity in patient populations should be accounted for. Based on the available results, the population of patients harbouring a high PD-L1 expressing tumour coupled with high TMB feature (≼ 20 mutations/mb) are most suited for a single-agent neoadjuvant checkpoint inhibitor regardless of their cisplatin eligibility. Adjuvant Immunotherapy Trials Although most of the findings achieved in the neoadjuvant context came from small academic studies, large phase III trials are recruiting patients with a high-risk disease postoperatively to receive adjuvant immune checkpoint inhibitors (NCT02632409, NCT03244384, NCT02450331). Indeed, the possibility to administer well-tolerated compounds in this context yields the potential to overcome the limitations of chemotherapy delivery, mainly related to the impossibility of timely administration of treatment after radical cystectomy because of the length of postoperative recovery. The adjuvant immunotherapy studies share similar inclusion criteria, mainly represented by pT3-4 and/or pN+ residual disease in patients who have already received neoadjuvant chemotherapy or who are ineligible to receive adjuvant cisplatin-based chemotherapy. If, on one hand, it is likely that such

studies will set new standard therapies in MIBC, on the other hand it is important to outline that the overall improvement in outcome is more likely to come from the integration of pre- and postoperative strategies, which is being planned in the next phase III trial (NCT03661320). Conclusion In conclusion, the revolutionary road of immunotherapy in UC that started in 2016 with atezolizumab studies has now produced the first outcomes in the nonmetastatic clinical stages. In MIBC in particular, there is potential for a revitalised multidisciplinary collaboration that allows patients with organ-confined disease to receive potent systemic therapies, with the aim of improving long-term outcomes, quality of life, patient adherence to treatment, and, likely, the proportion of bladders spared after curative treatment.
