thanks for your replies Joanne and gail.
My team seems to think that chemo could be an option, although one that may have limited reduction in overall survival but with significant side effects.

About ethyol, it is interesting to see positive outcomes but clinical studies have shown that up to 35% of patients still retain use pr partial use of their parotid gland even beyond the recommended levels of 30gys. Ethyol increases that rate by about 20% so it is hard to say if the effect is really from the ethyol or not.

My biggest concern I guess comes from the decision of getting RT now or saving it possibly for another time in the future. If you have watched that show "Who wants to be a millionnaire", you will know that you get 3 lifelines i.e. help in some form from the outside.
The analogy here is: do I want to use one of my lifelines now or save it for later when i might really need it.
