Official Title: Pilot Study of the Effect of High Doses of Radiation on Bone Metabolism and Structure in Patients Treated With Adjuvant Radiotherapy and Surgery for Sacral Tumors
Brief Summary: This study is designed to characterize the effects of high energy radiation on bone breakdown, with a specific interest in reducing the rate of sacral fractures. Although radiation is very important in managing tumors, it is related to complications such as bone fractures. In this research study, the investigators are looking to determine changes in blood markers, bone density, and bone structure following radiation and to better understand the reason for these changes.
