DJR, my wife has a case similar to your dad. She was diagnosed with NSCLC 10/02, with five bone mets, including the left hip. She also had pain in the hip as well as the upper back where the main bone met was. She went through radiation on three of the sites, and started chemo. But she was in the hospital most of Dec. from dehydration and infections. One can get dehydrated easily on chemo or radiation if you are not taking in enough liquids. And if you are doing chemo and radiation at the same time, it is almost impossible to keep up the liquid intake and may need IV once a week. She spent most of January recovering. When we started chemo again it had been a two-month gap. She was on carboplatin and taxotere, like your dad. After five treatments this year, the small tumors in her lung disappeared and as far as we can tell, the bone mets are gone (it is harder to tell with bone). However, she has developed recently a bone met in her sacrum and is presently undergoing radiation for that. We feel hopeful that she will beat this thing. Good luck to you and your dad. Don
