Information on Iressa

Has anyone undergone treatment with Iressa, the experimental cancer drug? If so, I'd like to hear from you. Specifically, I'd like to know how you are responding to the drug and whether you have any side effects. I need this information for my mother in law who was diagnosed with Stage IV NSCLC in April 2001, with mets to the brain, adrenal glands, spine, and liver. She has undergone radiation and chemo (Taxol and Carboplantin) which did not work.
I can be reached by e-mail at: jacobsr@howrey.com
Thanks so much for any help you can give.
Robert
