Outcome of surgical treatment of pelvic osteosarcoma

Background and objectives Surgical treatment of pelvic osteosarcoma is often challenging. The objective of this study was to assess the oncologic and functional outcome and the operation-related complications of patients with pelvic osteosarcoma who were treated in a single center in the past decade. Methods Nineteen patients underwent surgical procedures between June 2000 and June 2009. There were 11 males and 8 females with a mean age of 30 years. According to Enneking and Dunham pelvic classification system, there were: Type I-3, Type I?+?IV-3, Type I?+?II-2, Type II?+?III-4, Type I?+?II?+?III-1, Type III-1, and type I?+?II?+?IV-5. All patients received chemotherapy. Results Local recurrence rate was 26.3% (5/19). The 5-year overall survival rate was 44.9%. Seventeen patients received reconstruction after tumor resection. The average MSTS 93 score was 18 (1023) for the 11 patients with hemipelvic endoprosthetic reconstruction and 23 (2025) for 6 patients with rod-screw reconstruction. Complication was found in 7 of 19 patients (36.8%). Conclusion The oncological results of pelvic osteosarcoma are poor at best. Even with a higher complication rate, we believe restoration of pelvic ring continuity and hip joint mobility is reasonable option to achieve favorable functional outcomes in selected patients. J.
