Carlos -- i had a bone and ct scan, both negative. my biopsy showed 12 of 12 cores positive. one core was 70%, two were 60% and another was 40% and then smaller amounts. based on cancer volume, gleason score, PSA, negative DRE and smallish prostate my doctor said there was a 2% chance that the cancer was systemic and a 60% chance of local spread -- i.e., in the prostate bed.
so i started with lupron which was continued for 9 months. about 10 weeks after the first shot i had BT which was followed by IGRT.
sure i'll never know what the actually pathology was but it doesn't really matter since we threw everything at the cancer. we do know there is a 40% chance that the actual pathology is worse than what the biopsy shows and that adjuvant treatment is more effective than salvage treatment.
the comment you made about having surgery to better gauge recurrence doesn't sit well with me. but maybe i'm misinterpreting what you or your doctor said. whatever you decide i wish the very best outcome for you.
