Researchers Report New Findings on Metastatic Castration-Resistant Prostate Cancer Treatment Resistance
prostate cancerA recent study on metastatic castration-resistant prostate cancer (mCRPC) showed that androgen receptor V7 (or AR-V7) status has no significant impact on the response to taxane chemotherapy. The study entitled “AR splice variant 7 (AR-V7) and response to taxanes in men with metastatic castration-resistant prostate cancer (mCRPC)” was presented during the 2015 Genitourinary Cancers Symposium held last February in Orlando by lead author Dr. Emmanuel S. Antonarakis from the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins in Baltimore, MD. Dr. Antonarakis explained in a news release that clinicians urgently need biomarkers to decide which therapies will be effective at the individual level in advanced prostate cancer patients. Dr. Antonarakis said that testing for AR-V7 could become a very useful method to manage therapy decisions for men with hormone-resistant disease. The truncated form (AR-V7) of the androgen receptor (AR) i.e. that lacks the ligand-binding domain but always remains active, is found in a third of patients with castration-resistant prostate c
