Has anyone tried this combination of drugs? Was it very helpful?

Previously my mom was on Taxol and Carboplatin which did not seem to help much. She can not get any more radiation and there is no option for more surgery. Her Oncologist said that there is aprox 34% chance that the cancer will respond to this. I thought the Dr was referring on all the drugs but now I want to double check to see if she meant just with the Tarceva. Reading the info on Tarceva it suggests that THE TARCEVA alone has a 34% chance of making the cancer respond, (with lung cancer). It seems like maybe I need to confirm with the Dr. on exactly what drug and or combiniation of drugs yield what chance of response.

Sorry I just realized I posted this in the wrong forum. I am getting tired after much time at all the Dr.'s offices and research.

Thank you,
Rick
