[Surgical treatment of musculoskeletal soft tissue sarcomas].

Treatment of soft tissue sarcomas requires an individual plan which considers interdisciplinary recommendations and the various clinical situations. Anatomical region, histological grading and typing, and tumor size necessitate adjusted methods of reconstruction. The biopsy should be performed at the institution where the patient is treated. In general surgical resection of the tumor will be the treatment of choice. Adjuvant therapies are applied according to anatomical region and size and grading of the tumor. Surgery alone is recommended only in small (<5 cm), superficial, low-grade sarcomas. Sarcomas larger than 5 cm in diameter should be treated by surgery and radiotherapy, achieving excellent results, although in high-grade sarcomas more than 50% of patients still will experience metastatic disease. In case of locally recurrent disease, surgical revision with tumor-free resection margins followed by radiotherapy should be the aim. This applies even for patients who had had radiotherapy after the first excision. In this case brachytherapy is a good modality of tissue-sparing treatment.
