title: Curative local control of malignant tumors in the acetabulum by intraoperative radiotherapy.
abstract: As treatment for malignant tumors in the acetabular region of the pelvis, radiotherapy, mainly in the form of intraoperative radiotherapy (IORT), was carried out in four patients. One had a malignant fibrous histiocytoma of bone and three had metastatic tumors from the stomach and lung. Over follow-up period, ranging from 3 to 46 months, satisfactory limb function was preserved in three patients; the fourth suffered from femoral nerve palsy as a complication of IORT. Cessation of growth was observed radiologically in all the tumors, and curative local control was proven histologically in two patients at autopsy.
