My uro did not want me to combine HT & RT, under the idea that the HT masks the effect of the RT. He likes to do one thing at a time. My medical oncologist agrees with that approach.
The RO wanted HT, but faced with two much more respected docs, did not insist.
I think they did the right thing, since my PSA started shooting up after RT. This way we knew the PCa was already well outside the prostate bed. At this point, based on bone scans, we are looking at likely hip and spine mets that have been there for a very long time.
But as everyone says, each case is a case. All are unique.
Keep a daily note of what is happening. It will help the doc if you have any issues, and will help you down the road as you want to build a time line.
