Salvage radiation decision: with or without hormone therapy?

My PSA after SRT (Prostate bed and lymph nodes) was detectable at 0.014 (Roche ultra sensitive test) when taken at 3 months after my last radiation treatment. My PSA went undetectable at 6 months after last SRT treatment to < 0.014 (Quest test). At nine months PSA (Roche test) went to < 0.006 and has stayed there. So don't be too discouraged should you not get to undetectable at your first test. My experience was as mentioned - it takes time for the radiation to do its job. Good luck.

Thanks. Very helpful. MSKCC uses a tolerance limit of < .05 to be considered undetectable so yours would have been considered undectable. Even if mine is ' undetectable' next week , I won't really know if was the radiation that did that or thr Orgovyx, ( since ADT does not directly kill cancer cells). The reason I say this because a guy I ran into at the radiation unit said his PSA was undetectable after a Lupron shot , but before he even started radiation.
