Approximately 5-10 of these tumors primarily involve the pelvis. Major advances in our understanding of sarcoma biology have led to advances in chemotherapy and surgical techniques that offer the patients with nonmetastatic disease the potential for longterm disease-free survival and cure rates exceeding 50 . This is especially true for the two most common bone sarcomas osteosarcoma and Ewing s sarcoma. In addition advances in preoperative imaging studies have allowed surgeons to define the anatomic extent of disease more accurately and thereby plan surgical procedures with curative intent more precisely. However these rates of cure for malignant tumors involving the pelvis are often lower than those involving the extremities. This may be due to the complexity of the anatomy of the pelvis making resection with wide margins very difficult. Until recently hemipelvectomy was considered the standard surgical procedure for the management of patients with pelvic sarcoma. The procedure however is disabling and sacrifices a viable extremity to achieve local tumor control. Predicated on an understanding of sarcoma biology surgeons have developed limb-sparing procedures that are intended to achieve local tumor control while maximizing function. New .
