To determine the overall survival of patients with Pelvic Ewing's Sarcoma treated in our unit and to identify prognostic factors in pelvic primaries that could be used to select patients who would most likely benefit from high intensity treatment. Between 1977 and 2009, 80 male and 66 female patients aged 2 to 60 (mean, 18) years with Pelvic Ewing's Sarcomas were retrospectively reviewed from the Royal Orthopaedic Hospital Oncology Service Registry. Treatments included surgery, radiotherapy, chemotherapy, or any of them in combination. Event-free (from presentation to recurrence) and overall (from presentation to death/latest follow-up) survival rates were calculated using the Kaplan- Meier method. Influence of various factors (age at diagnosis, gender, tumour site, metastasis at presentation, surgery (and surgical margins), radiotherapy, and type of treatment on survival was assessed using SPSS 14.0 statistical software.Aim
