I just received my first PSA 1 month post radiation. It has droped from 1.5 to .47. I know they say it really takes 3 months to see the full benefit from the radiation. My questions are should I wait the full 3 months or should I start ADT now and is this drop a significant one.

If it were me I would have started ADT before radiation...In fact that's what I did...

I also started ADT before my PSA rose after RP had similar numbers to yours. I am familiar with the Taxotere trial. it was not out when I started out though I'm not sure I would have joined it. I did take a look at the Sanofi-aventis trial for after surgery left me at T3b. But they would not have allowed radiation in that study. I opted out, but followed most of the study. Surgery, ADT, radiation in that order.

Can't say I know much about it, but I would say the radiation is working well. Sounds like it hit the bullseye.

If I were you, (and I am not), I would give my body a little rest and see what happens. I have not seen any studies that say that beginning ADT sooner or later is significant in effectiveness.

But that is why you have experienced and professional doctors advising you.

Good luck, and conbgrats on the early success.
