I chose the prostatectomy in major part because the scans suggested I might have EPE. So I wanted to nail that down. In the event the prostatectomy pathology report said there was none, that my Gleason was 3+4 (my biopsy suggested it'd be 4+3) no positive margins; no affected lymph nodes; no cribiform or intraductal; no metasis etc. But there was +PNI
I felt I was home but a year later I had BCR. And I've been dealing with it ever since. Apparently it was the +PNI that was the culprit in its escape.
I'd still choose the prostatectomy because of all the definitive info I got up front that then made my salvage radiotherapy much more well informed.
Another reason-
the adage I had drilled into my head over half a century ago at Ft Benning training as an infantry lieutenant for Vietnam-
"Lieutenant-always bring the boss bad news first.
Good news takes care of itself."

Good luck!!!
