Objectives: To determine overall survival (OS) and event-free (EFS) in children with rhabdomyosarcoma treated at the NCI. Methods: We reviewed the medical records of patients with rhabdomyosarcoma treated at pediatric oncology clinic INC between January 2002 and December 2009. We performed descriptive analysis of sociodemographic and clinical characteristics of patients; we calculated the survival function by Kaplan-Meier method. Results: We included 45 cases, 25 males, 30 were from rural area, the median age was 10 years (0-18). 31.1% of patients were classified as high risk, 42.2% intermediate and 20% low. The mean follow-up was 2.38 years (SD = 2.51). There were 28 events, the cumulative probability of survival was 21.9%. Of all patients 37.8% died, the cumulative probability of OS was 50.3%. There was no significant association between variables and survival analysis. Conclusions: The survival of our patients is comparable with other studies in developing countries, but away from the results of studies in European countries and the USA. Our patients present with advanced stage and poor prognostic factors.
