To the question about
the effectiveness of salvage radiation, I think Andrew Stephenson (Cleveland Clinic) is the go-to guy.
There are multiple factors that come into play--Gleason, PSA, margin status, SVI, etc, but the most important one seems to be the pre-radiation PSA. If you can start at 0.5 or before, the odds are the best.
His research is the basis of the nomogram on the MSK website.
Roughly, though, around 3/4 of men initially see their PSA respond to SRT. Within a few years, that drops to half. Then several years out, it's only about
25%. However, men who have a *complete* response (PSA falls below 0.1 after radiation) have better odds--about
1 in 3 are still free of PSA progression 10 years out. But those odds are for all patients--again, the stats are much better for men who get started early.
