LOCCISANO, Matías H et al. Outcomes of surgical treatment of soft-tissue sarcomas in adults. Rev. argent. cir. [online]. 2019, vol.111, n.3, pp.143-151. ISSN 2250-639X.

Background: Soft-tissue sarcomas (STS) are rare mesenchymal tumors with several histologic subtypes and different clinical patterns. Objective: The aim of this study was to describe the clinical and pathological characteristics and surgical outcomes of a series of patients with STS. Material and methods: The clinical records of 2403 undergoing surgery between October 2014 and April 2018 were retrospectively reviewed. Twenty-two patients (0.91%) presented STS. Results: Mean age was 52 years (range: 19-92) and 13 (59%) were women. The tumors were located in the lower extremities in 12 cases, head and neck in five, trunk in three and upper extremities in two. Fourteen cases (63.6%) were high-grade tumors. Pleomorphic sarcoma was the most common histologic type (32%) followed by synovial sarcoma (18%), liposarcoma (14%), and other types (36%). All the tumors were completely resected and five patients (35.7%) required amputation, four in the lower extremity and on in the upper extremity. Different reconstructive procedures were performed according to tumor size and location, including three free flaps. Those patients with high-grade sarcomas or with positive margins received postoperative radiotherapy. After a mean follow-up of 16 months, six patients presented local recurrences and four patients had synchronous metastatic disease in the lungs; all these patients had high-grade tumors. Overall survival was 86.4%. Conclusion: STS are rare and invasive neoplasms, widely distributed, requiring aggressive and occasionally complex surgical procedures. It is necessary to consider adjuvant treatments in selected cases and to maintain regular follow-up due to the high rate of recurrences and distant metastases.
