We are not doctors. When in come time to make a decision, the person with the most information is your doctor. That means ask him if he was your spouse what who you do?
That being said, in my opinion, if the Doc can go for clear margins and no chem/rad, then I would have gone down that path. But Being
HPV+ BOT the chance for good outcome with just Chemo/Rads is favorable.
My doc said go for Chemo/Rads only. He's thoughts were high rads BOT and neck was his best chance of no reoccurrence. Lower rads may be enough but why risk it.
Having surgery will also delay the start of chemo/rads, and you are going to radiate the surgical area. Surgery also introduces it our risks.
Chemo/Rad is brutal it will consume 6-8 months dealing with various issues. Please start doing all of the suggestions you has read on these posts. Having cancer is a full time job. So is care giving.
My advice is post often. The more the fine people know about your situation the better the advice is.
Good luck and see on the boards.
