INTRODUCTION: The management of pelvic sarcoma is challenging and goals of surgery are adequate oncologic local control, maintenance of optimum function with good quality of life. METHODS: We have evaluated the results of internal hemipelvecotmy including age, type of resection, reconstruction, radiotherapy or chemotherapy. From 2010 to 2016, 23 patients with pelvic bone tumors (13 with Ewing's sarcoma, 9 with Osteosarcoma, 1 with chondrosarcoma) were treated by surgical resection. RESULTS: The mean follow-up was 18 months (0.5-5) years. In 12 patients reconstruction was performed and 11 were without reconstruction. A total of 3 patients (13%) had an infection develop at a mean follow up of 1 month. Surgical debridement's and antibiotics in three patients led to complete recovery. One patient had sciatic nerve injury.One patient had injury to femoral vein; was treated with femoral vein reconstruction. Two patients (9%) developed a local recurrence and were treated with best supportive treatment. Distal pulmonary metastases were seen in four patients and treated with supportive treatment. Five-year disease-specific survival rates of all patients were 83%. The mean functional MSTS score was 18(14-24). CONCLUSIONS: Proper selection of patients, preopertive planning and wide surgical margins with reconstruction provides good functional outcomes following internal hemipelvectomy. The surgical site infection and flap necrosis tend to be minor complication and can be managed leading to optimal outcomes and justifies the need for this complex surgery. The oncological and functional outcome after internal hemipelvectomy suggests that it's an effective method for treatment of patients with pelvic sarcomas.
