Samarium Sm 153 and Stem Cell Transplant Followed By Radiation Therapy Patients With Osteosarcoma

Summary

RATIONALE: Radioactive drugs, such as samarium Sm 153 lexidronam pentasodium, may carry radiation directly to tumor cells and not harm normal cells. A peripheral stem cell transplant may be able to replace blood-forming cells that were destroyed by chemotherapy and samarium Sm 153 lexidronam pentasodium. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving samarium Sm 153 lexidronam pentasodium together with a peripheral stem cell transplant and radiation therapy may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving samarium Sm 153 lexidronam pentasodium together with autologous stem cell transplant and radiation therapy works in treating patients with recurrent or refractory, metastatic, or unresectable osteosarcoma.
