Results of surgical resection in pediatric pelvic tumors

Thirty nonmetastatic patients with malignant tumors of the pelvis underwent surgical resection between November 2000 and December 2009. The diagnosis included Ewing’s sarcoma (22), osteogenic sarcoma (four), chondrosarcoma (two), and synovial sarcoma (two). Eighteen resections included the acetabulum and 12 did not. Twenty-seven patients were available for follow-up. Follow-up ranged from 4 to 138 months (mean 43 months). Nineteen patients are currently alive. There were two local recurrences. The overall survival was 68% at 5 years. The Musculoskeletal Tumor Society Score ranged from 22 to 29. Surgery provides good local control and oncologic outcomes with acceptable function in these patients.
