I agree with David. This is your life. I do believe that trials are needed, but if there is a proven effective treatment I would stick with it. Not worth gambling my life on a maybe. Its different if its a non fatal disease, a do over is okay, but sometimes there are no do overs where cancer is concerned. To be honest, cisplatin is a powerful toxin. But compared to rads its okay. The effects are generally not as long term unless you get some of the more rare side effects - peripheral neuropathy, and hearing issues of course are always a possibility but if they notice this they will switch you to the older version carbo which has less of those type of issues.)
I think I would do the tried and true... then if there is a recurrence, and the tried and true didn't work I would opt for the
Erbitux... just my two cents.
