My mon has NSCLC stage IV with mets to the bone. She is having a very hard time dealing with the side of effects of chemo, and there has been little success. Her doctor is now recommending that she try Tarceva. I have read a lot of the posts on these boards discussing side effects etc- the information has been very helpful. Just wondering if anyone has had improvement with their bone mets? her cancer is adenocarcinoma. Any information would be helpful. Thank you!!
