No long term experience yet but Erbitux magnified the effects of radiation burn but appears to have worked well enough to avoid a neck dissection. My advice is to watch carefully the skin on the face and neck and really bug the care providers about radiation gel and creams. I ended up having to use Vigilon second skin burn dressings as my reactions were so severe . However, the docs at Georgetown University's Lombardi Cancer Center also repeated the observation that their patients with the worst rashes and reactions had the best clinical response. So far so good with recovery
