Hello, I am sorry to hear about your mom. My grandfather was dianosed last july with NSCLC with mets to the bone. He got on tarceva and had a pet scan about two months later. Overall there was a significant change in the areas in both the lung and the bone. However, in february after the third pet scan the cancer began growing again, his oncologist decided tarceva was no longer working for him and suggested chemo. He took one round of chemo in early march which made him extremely weak and nauseated. The doctors confirmed there was nothing more they could do and referred us to hospice. Unfourtunatley, he passed away a few weeks ago. But i will say, Tarceva definately prolonged my grandpa's life (quality of life too) and without it, he probably would have died a lot sooner than he did. Again, I am sorry, I hope everything works for your mom.
