I recently completed a series of Erbitux treatments, once a week for 7 weeks, in addition to 33 radiation treatments, for pharyngeal cancer which was fairly advanced and the surgeon couldn't operate unless he removed my voice box too. It is very effective for head and neck cancers with none of the harsh side effects of regular chemo. I got a rash on my face and a few other annoyances but overall it's not too bad to take. I saw my surgeon two weeks ago and there is no visible sign of any cancer left, but am awaiting a PET scan to be sure. So at least for me, it's great stuff.
