Radiotherapy is integral in the multidisciplinary approach to patients with musculoskeletal neoplasms. Multiple studies have established a role for radiotherapy as a definitive local treatment of unresectable lesions or when surgery might yield unacceptable functional outcomes, such as in Ewing's tumor or base of skull chondrosarcoma. Radiotherapy is also used as an adjuvant treatment after surgery with close or positive margins. In the metastatic setting, external beam radiotherapy and bone-seeking intravenous radioisotopes are used on a case-by-case basis for palliation. As radiotherapy and its delivery techniques have evolved, so has its role in treating tumors such as Ewing's sarcoma, chordoma and chondrosarcoma, osteosarcoma, primary lymphoma of bone, malignant fibrous histiocytoma of bone, and vascular tumors. Radiation can also be successfully used to treat unresectable or recurrent benign tumors, such as giant cell tumor and aneurysmal bone cyst. This article reviews the indications for radiotherapy for various bone tumors and summarizes some of the important data supporting its use.

Primary bone cancers are extremely rare neoplasms, accounting for fewer than 0.2% of all cancers. The evaluation and treatment of patients with bone cancers requires a multidisciplinary team of physicians, including musculoskeletal, medical, and radiation oncologists, and surgeons and radiologists with demonstrated expertise in the management of these tumors. Long-term surveillance and follow-up are necessary for the management of treatment late effects related to surgery, radiation therapy, and chemotherapy. These guidelines discuss the management of chordoma, giant cell tumor of the bone, and osteosarcoma.
