    Abstract:
    BACKGROUND AND OBJECTIVES: The purpose of this study was to review the outcomes after preoperative radiotherapy and definitive surgery for patients who initially had inadvertent excision for sarcoma. MATERIALS AND METHODS: Treatment records of 44 consecutive patients, who initially underwent unplanned excision of soft-tissue sarcoma between January 2004 and January 2012, were reviewed. All patients had clinically localized disease before treatment and received preoperative external-beam radiotherapy followed by definitive oncologic surgery at our institution. RESULTS: The median follow-up was 36 months. Residual tumor after preoperative radiotherapy and wound bed excision was identified in 39% (17/44) of the cases. Kaplan-Meier estimates for 5-year local control, recurrence-free survival, and overall survival are 95% (95% confidence interval [CI], 80-99), 86% (95% CI, 69-94), and 94% (95% CI, 79-99) respectively. Perioperative morbidity occurred in 25% of patients (11/44.) All patients with perioperative wound complications had lower extremity sarcomas. CONCLUSIONS: Optimal management for unplanned excision of soft-tissue sarcoma is unknown. Our institution has adopted the approach of preoperative radiotherapy, followed by definitive surgery. In our series of 44 patients, local control was excellent at 95%, with perioperative complications seen only in patients with lower extremity sarcomas, suggesting that this is a reasonable approach to manage inadvertently resected sarcoma.
