Abstract

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 (10–23) for the 11 patients with hemipelvic endoprosthetic reconstruction and 23 (20–25) 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.
