Surgical techniques such as limb salvage (LS) have been developed. Survival and adverse events have been widely studied in general series of ES, but there are few specific series of ES cases treated by LS, despite this being the most commonly used (surgical) approach. The aim of this study was to determine survival and prognostic factors in ES patients undergoing LS. Patients and methods: We analysed all ES patients treated between January 1984 and May 2008 and selected all those treated by systemic multimodal therapy and LS. We assessed the influence of patient characteristics, tumour parameters and therapeutic results in event-free survival (EFS). Results: Ninety patients were included. Fifty of them were treated by systemic multimodal therapy and locally by LS. ean age was 20 years. Overall survival (OS) was 68.8% and EFS was 60.6% at years. In the univariate analysis, pelvic location, age and response to chemotherapy were associated with poor prognosis. After multivariate analysis, poor response to treatment, pelvis location and age between 12 and 17 years were found to be independent prognostic factors. Dissemination at diagnosis was not a prognostic factor. Conclusions: OS and EFS in ES treated by LS were similar to findings in previous ES studies. factors are no different, except for the presence of metastasis at diagnosis.
