As Susan mentioned, I've experienced the worst Erbitux rash my CCC has ever seen but in your husband's case, I wouldn't be worried about the rash. It's not apparent to me whether your Husband ever got any chemotherapy these last nine years, as what I read is all surgery and radiation. What chemotherapy does your Husband's medical team recommend?
I do regret not insisting on a combination of Erbitux and Carboplatin or Cisplatin - especially when my CCC MO switched me to Carboplatin after my cancer came back, saying that in his opinion my Cancer was Erbitux resistant. I do NOT regret getting even more radiation (25 GY over the 72 prior).
If the cancer is back, and the surgeon can't operate, please ask your doctors about more radiation (my second dose was via CyberKnife instead of IMRT) and Combination Chemotherapy) So far that has worked for me but as you know all too well, once the cancer starts coming back one never knows.
