Prostate cancer and Zytiga and ZERO PSA
Has anyone attained undetectable psa while on Zytiga (Abiraterone) ? If so was the Zytiga discontinued at some point (before 24 mos) ?
I was diagnosed with Gleason 7(4+3) w P. lymph nodes metastasis. Completed 39 sessions of IMRT, 10 mos (two 6 mo. Doses) of Lupron , and 5 mos Zytiga.
Initial psa was 80+ and is now undetectable (reached <0.1 ng/ml after 60 days on Zytiga).
What is to be gained by continuing an expensive drug that has so many negative side effects?
