I was diagnosed Gleason 8 20 mo ago. PSA was 6.6, cancer was contained. Because of my hypertension I was not a candidate for surgery. I started Lupron in Dec 21, 20 doses of radiation in Feb 22, and will receive my last of four Lupron injections net month. The good news is my PSA is undetectable! I guess for the moment I can say I've beat it. The bad news is for me the side effects of Lupron honestly make me wonder if it's worth it. My quality of life has greatly deteriorated.
Read up on hormone therapy and decide. For me if I could do it over I would have had surgery and taken my chances of dying on the table. Best of luck.
