Hi,
Just remember there are so many variables with each surgery I think it would be hard to put a hard number on it. I know those number exists but each case is different. Where the cancer is located and how close to escaping the capsule, Gleason score, surgeon skill, ect, ect. If you tell us a little about your specific case other members will chime in with their experience. I had robotic surgery in 2014 with Pleural neural invasion and I am cancer free today. Other survivors have surgery with clear margins and two months later their PSA is climbing. That why tools like MRIs and PMSA PET scan are valuable tools in weighing in on your surgery success.
