Ac-I too had a month on prednisolone after my 6 doxetaxel infusions during which time my PSA dropped to 112 which is the lowest it’s been?? (started at 1547 in March), also now on a 3 month chemo and steroid holiday with only 4 weekly hormone treatments till Dec when I have my next oncology meeting.
Also at my last meeting my oncologist said that she fully expects my PSA to drop further by December even tho I’m only on hormones alone? So who knows what’s happening there?
As for Dexy I’ve only had limited experience of same usually in the days leading up to a chemo infusion.
Anyway hope it all works out for you,
all the best J..
