JNF, you said, "If he says he can't spare nerves I interpret that he is essentially predicting positive margins that will require radiation and the very risks he wants you to avoid."
I don't think that's true. For one thing, it was the PA who told Gleason 6 that the surgeon would probably not be able to spare the nerves on one side. I take PA's statements with a grain of salt. This past winter, the PA at the orthopedic surgeon's office told me that my problem was certainly a rotator cuff injury. Then the orthopedist himself came in and said, no, the injury I had suffered mimiced a rotator cuff injury, but that my symptoms were actually being caused by two herniated discs in my neck. The surgeon actually told Gleason the nerves can be saved 80 percent of the time, and especially in the case of a G6.
In my own case, the surgeon told me in advance he would likely not be able to save the nerves on my left side, because of the obvious tumor there. It wasn't a question of a positive margin, but a question of taking a safe approach when the nerves were essentially lying right on top of the tumor area.
I've begun to feel concerned when we second guess newcomer's doctors. I'm not talking now about anyone in particular at all. But, none of has even seen the one-page medical history we all have to fill out before we see the doc. We haven't laid eyes on the patient. We don't know what other physical conditions the patient may present with. We don't know what medications they are on. We don't know their blood sugar levels, their cardiac condition, their blood pressure, their weight, or anything about them. In fact, what we know is about like peeking thru the keyhole of the doctor's office. And then we sometimes suggest that the doctors are just trying to pad their own wallets and buy a new Porsche, or call them "salesmen" and so forth. I think we often go way too far in advocating for our own particular points of view rather than just making suggestions that they look into other treatment options.
I don't mean to say this site isn't the best around. I think it is, and it provides a tremendous amount of support. But we're not M.D.s, and we sometimes get beyond our depth. IMHO
