What you are missing is the whole point of SRT. The purpose is to cure you while it is still curable. That means before
any metastases are detectable. Once they are detectable, it is too late.
You are also misled in thinking that a PSA of 0.2 ng/ml is a "magic number." It is just an arbitrary number they came up with when the PSA tests weren't reliable at detecting number below that. They have such tests now, called "ultrasensitive PSA tests." You should have been monitored with such tests, especially because of your positive margins, and should have been treated when your PSA rose above 0.03 ng/ml.
The earlier the salvage, the better the oncological outcomes.
