Abstract
Introduction: Childhood cancer is a major cause of mortality. The aim is to characterize the population and determine the survival of child population in a reference center. Methods: Survival analysis patients younger than 18 years diagnosed with cancer 01/10/2010 to 31/03/2016. Socio demographic variables (age, sex, social security and area of residence) and clinical (type of cancer and risk categorization) were analyzed. The Kaplan-Meier and Log Rank Test was used. Results:135 patients were evaluated, the average age at diagnosis was 7,4 years (SD 4,84), mostly male, contributory scheme and urban residence. The most frequent neoplasms were leukemias and central nervous system tumors and most were high-risk. Overall survival was 75% and event-free survival of 60%. Solid and high-risk tumors had a higher mortality. Conclusions: The overall 5-year survival is similar to international data. Most solid tumors were high risk probably associated with a longer history.
