David--to answer your questions:

PEG was mentioned/recommended; it was actually scheduled but he asked to put it off until he really needs it so that he can keep exercising as long as possible (w/o having another procedure to recover from right before starting rad).

We read about HPV via on-line research and that seems like a possibility. In addition, the RO's nurse mentioned it (in the one real visit he had!).

ENT/RO planning on just the surgery/rad combo at this point.

Thanks for the comments and support; very much appreciated!
