Hope everything works out for you. Obviously my PSA wasn’t as high as your experiance but.......
As for Docetaxel I had 6 cycles last year, when first diagnosed, and it brought my PSA down from 1547 to 94.
However went back up to over 700 early this year so had 7 Cabazitaxel infusions which also brought my PSA down slowly, but nothing like the dramatic drop on Docetaxel.
Back up to 412 now so I’ve just started on the Radium 223 “bus” having had my 2nd of 6 infusions yesterday.
Hope this helps, click on my story to date for further details.
Keep the Faith
