I asked that same question down at MD Anderson. The answer was less than satisfying. They said that it depended on where the reoccurrence was located, plus absence of any spread, whether local or metastatic. As I've said before, two main factors in my case were age, 86 later this year, and having watched my ex-wife go through with the surgery. Had I been younger, I might have considered it. The possible extension of life span/QoL in my case just made the tradeoff obvious. I've just left a meeting where one of the attendees has had a brush with cancer and he's far younger than I. He observed that cancer doctors were like all other specialties - they're determined you're going to die of something else first - "not on my watch." I had to laugh, particularly at my age... 🙂
