A 73 year old male with PSA levels of 8.4. Histology shows adenocarcinoma invading into the right seminal vesicle. A 62 year old male undergoes radical prostatectomy for cancer. On histology, the carcinoma extends beyond the prostate into the periprostatic fat. A 68 year old male with elevated PSA levels has a normal prostate on clinical and radiological examination. Needle core biopsies from both lobes however, reveal an adenocarcinoma. A 52 year old male with obstructive symptoms undergoes radical prostatectomy. On histology, an adenocarcinoma involving both lobes, but confined to the prostate is seen. A 58 year old male with obstructive symptoms and a PSA of 38, undergoes a CT scan of the pelvis, which reveals a prostatic tumour extending into the levator muscles.

Prostate – Rules for Classification The classification applies only to adenocarcinomas. Transitional cell carcinoma of the prostate is classified as a urethral tumour. There should be histological confirmation of the disease.

Pathological staging of prostate cancer 

Tx – Primary tumour cannot be assessed



T0 - No evidence of primary tumour



T1 – Clinically inapparent tumour ◦ T1a: Incidental tumour <5% of total tissue ◦ T1b: Incidental tumour >5% of total tissue ◦ T1c: Tumour identified by needle biopsy

Pathological staging of prostate cancer 

T2 – Tumour confined to the prostate



T3 – Tumour with extra-prostatic extension



◦ T2a: Tumour involving not more than one half of one lobe ◦ T2b: Tumour involving more than one half of one lobe ◦ T2c: Tumour involving both lobes ◦ T3a: Extracapsular extension (including bladder neck) ◦ T3b: Tumour invades seminal vesicle(s)

T4 – Tumour invades adjacent structures other than seminal vesicles (ie. external sphincter, rectum, levator muscles and/or pelvic wall)

Pathological staging of Prostate cancers

Pathological Staging of Prostate Cancer N – Regional Lymph Nodes NX – No regional lymph node metastasis N0 – No regional lymph node metastasis N1 – Regional lymph node metastasis

M – No distant metastasis* M1 – Distant metastasis M1a – Non-regional lymph node(s) M1b – Bone(s) M1c – Other site(s) Note: *When more than one site of metastasis is present, the most advanced category is used. pM1c is the most advanced category.

1. A 73 year old male with PSA levels of 8.4. Histology shows adenocarcinoma invading into the right seminal vesicle – pT3b 2. A 62 year old male undergoes radical prostatectomy for cancer. On histology, the carcinoma extends beyond the prostate into the peri-prostatic fat – pT3a 3. A 68 year old male with elevated PSA levels has a normal prostate on clinical and radiological examination. Needle core biopsies from both lobes however, reveal an adenocarcinoma pT1c 4. A 52 year old male with obstructive symptoms undergoes radical prostatectomy. On histology, an adenocarcinoma involving both lobes, but confined to the prostate is seen - pT2c 5. A 58 year old male with obstructive symptoms and a PSA of 38, undergoes a CT scan of the pelvis, which reveals a prostatic tumour extending into the levator muscles – pT4

A 66 year old man undergoes radical prostatectomy for a needle core detected adenocarcinoma. The tumour predominantly shows raggedly infiltrating single and separate glands of varying sizes. Approximately 5% of the carcinoma also shows rounded tumour masses with central necrosis. Which of the following best represents the grade of the tumour?

A. Gleason’s 3 + 3 = 6 B. Gleason’s 3 + 4 = 7 C. Gleason’s 4 + 3 = 7 D. Gleason’s 3 + 5 = 8 E. Gleason’s 4 + 5 = 9

Introduction 

In the 1960’s and 1970’s, Donald F Gleason and collaborators characterised various architectural patterns of prostatic cancer and grouped them into 5 grades or patterns, thus establishing the Gleason grading system  More than 4 decades since its introduction, the Gleason system still remains the key prognostic factor in patients with prostatic cancer

Gleason’s grading

Original Gleason diagram diagram

Modified ISUP

Intro contd... 

Thus, a 2005 ISUP modified Gleason system was proposed, outlining the morphological patterns 15, which were accompanied by a modified diagram, similar to the original Gleason system  It was reiterated that GP1 and GP2 are quite rare on biopsy and

prostatectomy. The most significant modifications pertained to patterns 3 and 4  GP3 was restricted to discrete glandular units and to smoothly

circumscribed but only small cribriform tumour nodules

Intro contd... 

Pattern 4 included fused glands and large cribriform glands or cribriform glands with border irregularities, as well as hypernephromatoid glands  Additionally, a category of ill-defined glands or glands containing

poorly formed glandular lumina was introduced under GP4  GP5 was reserved for cancers containing essentially no glandular

differentiation, composed of solid sheets, cords, and single cells. Comedocarcinoma with central necrosis was also retained in pattern 5

TABLE 3. 2005 ISUP Modified Gleason System (Patterns 1+2 removed)

Pattern 3: Discrete glandular units Typically smaller glands than seen in Gleason pattern 1 or 2 Infiltrates in and amongst nonneoplastic prostate acini Marked variation in size and shape Smoothly circumscribed small cribriform nodules of tumour

Pattern 4: Fused microacinar glands Ill-defined glands with poorly formed glandular lumina Large cribriform glands Cribriform glands with an irregular border Hypernephromatoid Pattern 5: Essentially no glandular differentiation, composed of solid sheets, cords, or single cells Comedocarcinoma with central necrosis surrounded by papillary, cribriform, or solid masses

Cribriform prostate cancer with perineural invasion. Cribriform glands with round border (arrow) Cribriform glands with irregular border (arrowhead) – both now Gleason 4

Gleason score 4 + 4 = 8 adenocarcinoma Fused Glands

Large irregular cribriform

Gleason pattern 5 cancer with cribriform gland containing central comedonecrosis

Gleason’s grading tutorial – pathology.jhu.edu/prostate

◦ Grade obtained by adding the most prevalent (primary) and the second most prevalent (secondary) pattern +/- any tertiary pattern (if 4 or 5)* ◦ Grade obtained by adding the most prevalent (primary) and the highest

*A pattern is secondary if it accounts for at least 5% of the tumour, and tertiary if it is < 5% of the tumour

Testis – germ cell tumours The classification applies to germ cell tumours of the testis. There should be histological confirmation of the disease and division of cases by histological type. Histopathological grading is not applicable.

The presence of elevated serum tumour markers, including alphafetoprotein (AFP), hCG and LDH, is frequent in this disease. Staging is based on the determination of the anatomic extent of disease and assessment of serum tumour markers.

Testis Serum tumour markers are obtained immediately after orchidectomy and if elevated, should be performed serially after orchidectomy according to the normal decay for AFP (half-life 7 days) and hCG (half-life 3 days). The serum level of LDH (but not its half-life levels) has prognostic value in patients with metastatic disease and is included for staging.
