Just to give you a little confidence in the lack of conventional chemo in you plan, I had radiation and neck dissection only. No Chemo�. and here I still am. In my day going through this (back when Moby Dick was a minnow) IMRT didn't exist, and the studies which showed the additional survival benefits of chemo/rad had not been completed. They had however determined that fractionated radiation treatments were the winning path in radiation.

The adverse event report show frequent enough minor anaphalactic reactions, which are controlled, and stops the treatments immediately. Given that this is widely reported, and that there is no test (it isn't just tick antibodies that can cause this) to predict it, my assumption is that this initial monitoring protocol is not unknown. But I haven't read about it much in the literature, and fatalities are very rare. I will be curious on Tuesday when the docs I get to interact with, get my questions about this at their institutions.
