An update on my situation. To review, I now appear to be castrate resistant after about 6 1/2 years of being castrate sensitive. My MO put me on Abiraterone, along the existing Lupron. I had my MO appt and my PSA has fallen from 4.5 to 2 after about 7 weeks on Abi. This is my second iteration with Abi. I was put on it, along with Lupron, when I was first diagnosed. Side effects are much less onerous this time around with Abi. I really just have the same SE's I've experienced wtih Lupron: relatively mild hot flashes and moderate fatigue. No increase in those this time. My last experience with Abi was that my SE's, while the same as Lupron-only, were more intense with Abi added to the Lupron. And my liver numbers went wonky when first put on Aib last time. All looks good this time.
So I have my next Lupron injection at the end of May and my next MO appt is in Aug/Sept, assuming my PSA stays good. I'll go in for one or two PSA tests before the MO appt just to make sure my PSA is behaving. My MO has put up standing orders for me to get PSA tests whenever the mood strikes me.
So, the beat goes on ...
