Can Devices Provide A
New Treatment Option for Glioblastoma? Experts at the Houston Methodist Kenneth R. Peak Brain & Pituitary Tumor Treatment Center are developing new glioblastoma multiforme (GBM) treatment options, including an innovative technology that provides anticancer therapy through a wearable device.

“
We believe that our current investigations may help to establish Oncomagnetics as a GBM treatment that does not have the limitations of chemotherapeutic agents. Given that various cancerous cell types are susceptible to apoptosis by OMF-induced accentuation of reactive oxygen species, we hope to modulate our nascent OMF treatment to target other cancers.
