I had a positive margin --- my doc told me that it was all in the PSA post surgery. We checked it quite often --- my PSA DID rise about 5 months later, and that's when I went to the radiation oncologist.
I did a lot of reading in the mean time --- there are a lot of guys with positive margins that don't have a recurrence --- but it CAN suggest some cancer got left behind that can successfully be treated with salvage radiation. I read some studies where some advocate radiation with a positive margin BEFORE the PSA rise ---- I would guess other factors (gleason, PSA before surgery, etc) come into play on that decision. I came to the conclusin that I would radiate at the first PSA reading north of .2 ---- which is what I did, along with 6 months of hormone therapy.
So far so good 2 years post dx...hope this helps...GOOD LUCK!
