Surgical Management for Malignant Musculoskeletal Tumors in the Pelvis

We conducted a clinical study in 19 patients who underwent surgical management for malignant pelvic tumors. Treatment included wide resection, hemipelvectomy and intraoperative radiotherapy (IORT) in 3, 8 and 8 patients, respectively. IORT was applied for aged patients or those in a poor general condition. Local recurrence did not occur in any of the patients who underwent wide resection or hemipelvectomy.Using TORT, curative local control was also achieved in 5 of 8 patients. Modifying the IORT could improve the clinical value for malignant pelvic tumors.
