Darsdaughter, appreciate your reply. Would like to know if your mom was in remission when she was taking Tarceva, after having had chemotherapy. My doctor says that I am out of the statistics, the tumor having shrunk, and having been stable for a year (after a weekly session of chemo for a period of a year). Therefore, it is important for me to know if I will be upsetting the apple cart by starting up with a medication that is still being tested, while chemo (Gemzar) did work for me. Of course, it would be great to help others by participating in a clinical trial and wish I could do so without putting myself in jeopardy. Hope your mom is doing O.K. I wish her many blessings.
