Jim,
My mom actually never had the Tarceva. They gave her Herbatux. She was suppose to have 5 or 7 treatments but she only did 2(unfortunatly). Hopefully that was enough. The rash was so bad and it intensified the radiation so much she just couldn't do anymore. She did complete her course of radiation. Which they increase from 33 to 37 treatments. She goes in for her first MRI and chest x-ray on Monday. So we'll keep our fingers crossed!!!!!! Good luck with you treatment. By the way are you opting for the feeding tube? I strongly recomend it.
