What is advanced castration resistant prostate cancer?
What is mCRPC? Castration-resistant prostate cancer (CRPC) is a form of advanced prostate cancer. With CRPC, the cancer no longer completely responds to treatments that lower testosterone. It shows signs of growth, like a rising PSA (prostate-specific antigen), even with low levels of testosterone.
What does castration naive prostate cancer mean?
The term “castration-naive” is used to define patients who are not on ADT at the time of progression.
