I ran across a study in Japan that showed an unacceptable number of deaths from side effects of Iressa, as well as no benefit from it's use. I have no way of verifying this information and I didn't save the web page. I did find it by searching "iressa" in google. I guess caution would be the word I'd use.

Mark, 21 Year survivor, SCC right tonsil, 3 nodes positive, one with extra-capsular spread. I never asked what stage (would have scared me anyway) Right side tonsillectomy, radical neck dissection right side, maximum radiation to both sides, no chemo, no PEG, age 40 when diagnosed.
