Question for Salvage radiation verterans or other informed readers

After salvage radiation what is the average period of time to psa nadir.  I have read that it is between 6 and 18 months on external radiation to the prostate as the primary treatment but can't find anything on averages for salvage radiation.  Input appreciated.

Great question! I am curious about this too, however, my father is on HT, so I don't know if his PSA will necessarily be accurate, but we will take all the O's we can get :)

What about you other guys out there....how long did it take your PSA to drop following salvage radiation?

I'll be curious to see the responses... I was on hormone therapy for 6 months concurrent with salvage radiation--- so my first PSA a few months after treatment radiation was undetectable...

It took about 6 months for the hormone block to wear off, so I'm not sure my PSA at undectable 6 months ago  means a whole lot--- getting checked in 3 weeks --- hoping/praying for undectable then!
