Angie, my wife, Lucie, has NSCLC, with bone mets. She had chemo treatment (carboplatin and taxotere), which helped a lot. She also had radiation on 4 mets, the main one on the upper spine. Their criteria for radiation were: (1) Is it causing a lot of pain? and (2) Is the met threatening the bone integrity. I would think your dad's spine met could be treated with radiation, and I agree with others that a rad onc should be consulted. Lucie has been on Zometa since June and we believe it has helped a lot to keep new bone mets from forming. Good luck. Hang in there, and keep us posted with your thoughts, feelings and questions. Don
