Summary

This study tests whether giving a precise, high-dose radiation treatment (SBRT) to bone tumors before surgery is safe and can prevent the cancer from returning. About 39 adults with cancer that has spread to their bones and who need surgery to stabilize a fracture risk will receive SBRT followed by surgery within a week. The main goal is to check for serious wound complications and see if the cancer stays away from the treated bone.
