The aim of the study is to retrospectively evaluate the outcome of adjuvant concurrent chemoradiation delivered to patients with high grade non-metastatic soft tissue sarcomas of the extremities at the investigators institution paired with patients treated by adjuvant radiation therapy

Inclusion Criteria:

• All patients consecutive enrolled from 1990 to 2004 with soft tissue sarcomas located either in the limbs or girdles, superficial or deep, grade 2 or 3 (FNCLCC), who were first treated with radical conservative surgery and adjuvant RT atto a minimum biologically equivalent dose of 45 Gy, with or without concurrent adjuvant chemotherapy.

Exclusion Criteria:

• A patient record captured outside the time frame from 1990 to 2004 with trunk, retro-peritoneum, and head and neck localisations, grade 1 histology and, PS≥3, were excluded as well as and those plus patients who had received neoadjuvant treatment. Differentiated liposarcomas, dermatofibrosarcomas protuberans, extraskeletal Ewing's sarcomas, primitive neuroectodermal tumors and osteosarcomas were also excluded due to specific treatment strategies.
