Hi, Christine, and welcome. Hold onto hope. My wife was diagnosed with NSCLC, Stage IV (bone mets), 26 months ago. She has not only staved off the cancer with chemo and radiation, but she has weathered a systematic staph infection and bilateral pneumonia on the way. I agree with the others that you should get a second opinion on treatments. As long as there are ones out there (and there are some milder than what your mom is taking), you should investigate. There are Iressa, Navelbine, Gemzar, Alimta, Tarceva. etc. Good luck, and keep us posted. Don
