Hi all,
My father was diagnosed with PC in Nov 2017, Gleason 4+4 PSA 12 and had is prostate removed in January. His PSA however started immediately to rise from 1.7 in feb, a month after surgery to 7 in March and 21 mid April (tripled every month). His scans showed Mets in the spine and lymph nodes. He started casodex and then got a 6 month Eligard shot beginning of May. He then started Zytiga mid May. His PSA beginning of June was 44 and today his PSA is slightly down to 42. His testosterone is below 0.25.
Does this mean he is castrate resistant? From reading the forums I had understood that most people see a fast drop in PSA after the hormone shot and his seemed to have risen and then only went down slightly, which may also be due to the abiraterone. I’m really worried that we may have gone directly to castrate resistant phase and perhaps he should be receiving different treatment such as chemo. Has anyone here not responded to hormone shots at all? Any insight would be much appreciated. Thank you all very much.
