Introduction: Soft tissue sarcomas (STS) are rare tumors. A multidisciplinary approach including surgery, chemotherapy and radiation therapy is recommended.

Materials and Methods: In the last 12 years, 249 patients with STS were teated in our Institution. All of them were treted with a multidisciplinary approach using all or some of the previous refered treatments.

Results: The overall local recurrence rate in the group of patients submited to surgery was 25% and this factor was related mostly with contaminated margins. Surgical resections were associted with soft tissue reconstructions when needed.

Radiation therapy was used in both regimens pre and post operativly, chemotherapy was also used in 85% of the patients, and was not dependent of tumor histotype.

23 patients were submited to surgery of lung metastasis.

Survival rates were determined and compared with stage (AJCC), tumor histotype and surgical margins.

Conclusions: Multidisciplinary approach is the recommended treatment for STS.
