Good Morning hatter,
MSK with Eastham...one of the best!
Did he show you the online MSK nomograms? Go here: http://nomograms.mskcc.org/Prostate/index.aspx
Then, select the Post-Radical Prostatectomy (Recurrence After Surgery).
You might also get some anecdotal replies in this thread, like "Here's what happened to me...," but at this point what's meaningful to you is the big picture about what happens to large populations of men like you. Or more specifically, what's the likelihood (statistical probability) of recurrence in men like you.
Try out it out... You can toggle back and forth different inputs to see what the differences are with and without EPE.
