The survival of children treated with Ewing sarcoma at Semmelweis University were investigated. Pediatric patients with Ewing sarcoma treated at Semmelweis University from 2001 through 2013 were analyzed in terms of overall survival and clinical factors (age, primary localization and extent of the tumor, time interval from primary complaints to diagnosis). For statistical analysis Kaplan-Meier estimated survival and log rank test were applied. Mean age and follow-up time of the 78 patients were 11.16 and 6.29 years, respectively. In 57% of patients time interval from primary symptoms to diagnosis was less than half year. In 53.8% of the patients the disease was metastatic at primary diagnosis (pulmonary only: 29.5%, any other: 24.3%). 5- and 10-year overall survival of patients were 68.1% and 60.4%, respectively. Among the analyzed factors, the presence of metastasis impaired 5-year overall survival significantly (88.5% for localized disease, 63.5% for pulmonary only and 40.9% for any other metastasis). The survival rate of pediatric patients with Ewing sarcoma treated at Semmelweis University is similar to the result in Western European countries.
