Unplanned resection of soft tissue sarcoma

Publication date: Available online 22 July 2015 Source:Formosan Journal of Surgery Author(s): Cheng-Fong Chen, Po-Kuei Wu, Wei-Ming Chen Unplanned surgery of a soft tissue sarcoma is defined as the gross removal of a tumor without appropriate preoperative imaging, biopsy, or attention to the wide surgical margin. Referrals after unplanned surgery account for between 14.7% and 53% of new patients in sarcoma centers. Treatment includes multiple modalities. It has been reported that 35–74% of residual sarcomas are found in reexcised specimens. Therefore, additional reexcision is typically warranted to remove the residual tumor and obtain an adequately safe margin. Adjuvant radiotherapy is generally used if the sarcoma is large, high grade, and deeply located. Adjuvant chemotherapy remains controversial because of its marginal benefits. A recent study indicated that adjuvant chemotherapy, an ifosfamide/epidoxorubicin protocol, showed 19% improvement in overall survival at 4 years. Therefore, adjuvant chemotherapy should be reserved for patients with a large, high-grade, localized lesion, and stage-IV disease. Unplanned surgery of high-grade sarcomas has resulted in increased rates of local recurrence but not disease-specific survival. Adequate additional reexcision may improve local control and survival. To avoid unplanned surgery of soft tissue sarcomas, guidelines have been recommended for clinicians to increase their awareness of the clinical features that suggest ...
