Hi hiitsme
Your journey has been almost a mirror of mine. Was diagnosed Sept 2016 PSA 1000+, Gleeson 9.5. Hormone therapy started straight away, with a PSA down to 130 within six weeks. Started chemo (Docetaxel - 6 session, three weekly) PSA went to 0.15 after two sessions; having had a scare with very low white blood cell count along the way. But developed anal abscess that became a fistula and need surgery to correct (ouch!). After surgery was fully healed chemo was suspended as it was thought that the remaining sessions wouldn't be helpful but I stayed on the hormone therapy.
A blood test in March revealed that my PSA had risen to 11 and it was decided to resume chemo again. As they also wanted to start injections to support metatistised bones I needed to have an abscessed tooth removed; this took three weeks to heal. Having started chemo again I've just had the second cycle to this new regime and my PSA has risen to 31. Obviously this is very disappointing but I'm hoping that all these new interventions will get on top of it but only time will tell. Feeling good at the moment and I'm sure it will come around eventually.
Hope this helps in some way and underlines that it's not a straightforward journey for any of us. Best of luck and best wishes for your on-going journey.
