John: a positive surgical margin is a Bad Thing as it means positive for cancer -- contrary what we might normally think. A negative margin is desirable as it means clear of cancer.
I am a bit confused by your stats which say "location of tumor makes positive surgical margin unlikely" -- does this mean that the tumor is unlikely to be confined to the prostate? If so, surgery is a less attractive option, and radiation becomes relatively more attractive.
