I am a numbers guy, and like to use available "nomograms" for PCa probabilities. These are based on statistics gathered over hundreds, even thousands, of men who have had prostate cancer. Although nothing is guaranteed with cancer, statements that recurrence "can" or "sometimes" happen need to be taken into context with actual recurrence rates. I have been using the Sloan-Kettering online nomograms at:
but others may have even better tools. These tools, based on actual underlying case data, show that reccurence rates can be extremely low with surgery, especially for negative margins and no capsular penetration. Multi-year disease-free survival is often in the very high 90's percentage range.
