For those who follow me-
Radiation of my largest tumor after 10 years of ADT (Lupron and Zytiga) appears to have been "successful". My PSA had steadily climbed the last year up to a high of .32 and the doubling time increase was a concern. PSMA scan indicated "activity" in only my largest tumor. It was radiated. 4 weeks thereafter, PSA dropped to .05. yesterday, 7 weeks after the radiation, my PSA is now <.05, which is as low as MSKCC measures. So, for now, I will continue with the ADT treatments.
