We aim to analyse the cancer survival time of children and adolescents (0-19 years) residents in Campinas, Southeastern Brazil diagnosed in 1996- 2005, attended in the reference service of childhood cancer. This is a cohort retrospect study and the follow-up censored date was December 31, 2011. Cancers were classified according to the International Classification of Childhood Cancer Groups. By design, just the 4 most common groups were studied: Group I, Group II, Group III and Group IX. Kaplan-Meier estimation methods, log-rank test and Cox regression were used for survival analysis. A total of 180 cases were diagnosed during the study period. Significant differences in survival times were found by diagnostic groups adjusted for age and sex (p=0.001). In conclusion, five-year survival was higher in children than in adolescents similar to the findings reported in the literature.
