My husband, three years ago was diagnosed with stage 4 squamous cell carcinoma, our doctors advised the following, : Get all your teeth fixed, he did, he was given a trach tube and a peg tube in his stomach. He had 35 radiation treatments and 3 chemo (sisplatin) he was totally out of it. I fed him every four hours and continued with anti-nausea meds, by the way, fenergan and reglan worked the best alternating them every four hours, long story short, three pets scans all clean. He is living the good life, still can't eat solids, but that's ok, he's alive!! Golfs, bowls and does everything he did before except that big steak. He wants to help any one who is in doubt or is strugglling. Get a good doctor, and listen to them, and don't give up
