I don't find part 2 posted under your name in discussions. I had 35 weeks of radiation and a targeted therapy Cetuximab back in 2012 after surgery for ear canal based SCC, not HPV related. It has not recurred there but I have had metastases. I know that HPV 16 tumors tend to respond well to radiation, and I have been reading some of the literature on the reduced dose. It sounds like it will produce equal results with less side effects. I hope you have had success with this protocol and are feeling strong in dealing with the side effects.
