[Pediatric soft tissue sarcomas: analysis of non rhabdomyosarcoma group]

We evaluated 29 patients with non rhabdomyosarcoma soft tissue sarcomas treated with surgery between 2000 and 2010; we analyzed overall survival and which factors affect the prognosis. The mean age was 11.6 years (range 3 months-17 years); 16 patients were males and the median follow-up was 56 months (8 to 132 months). Eight different histological malignant tumors were identified, being synovial sarcoma the most prevalent one (14 patients). Twenty-eight patients were treated with limb salvage surgery and in 26 cases, adjuvant therapy was used. Five years overall survival was 72%. Nine of the 29 patients presented a local recurrence. The presence of metastases (p <0.0001) and local recurrence (p <0.007) were negative prognostic factors for overall survival.
