This is just a shot in the dark. but what about cyberknife to shrink the tumor, which is highly accurate, followed by chemo therapy, the same with brachytherapy, which can be place by needles for a a few days in the tumor, or as,one dose, or permanent seeds, maybe followed by chemo. You may want to ask or into,it. I had intraoperative, IORT, which is high dose radiation during surgery, but the area was resected before doing it, and then Chemoradiation weeks later. With IORT the rad prongs go directly on the tumor, and vital areas are protected by molded lead shields, and or clamped out of the way. I had a pec flap to get more radiation, protect my carotid artery. Good luck with your 2nd opinion. Not every doctor will tell you different options if the don't do them at their hospital. Mine didn't, and had to look.
