BACKGROUND: An increased incidence of retinoblastoma in some developing countries has been reported but no conclusive data are available from population-based studies at national level. PURPOSE: To report the incidence and survival of retinoblastoma in Argentina from the National Pediatric Cancer Registry (ROHA) and the influence of socio-economical indicators on outcome. PROCEDURE: Cases reported to the ROHA (2000-2009) were analyzed. Incidence rates were calculated using National Vital Statistics and survival was estimated. The extended human development index (EHDI) was used as a socio-economical indicator. RESULTS: With 438 patients reported, an incidence of 5.0 cases per million children 0-14 years old (95% CI 3.5-6.4) was calculated. Median age at diagnosis was significantly higher for children from provinces with lower EHDI; (24 vs. 35 months for unilateral, (P = 0.003) and 9 versus 11.5 months for bilateral retinoblastoma (P = 0.027). The 3-year probability of survival was 0.87 and 0.94 for unilateral and bilateral retinoblastoma, respectively. Residents in provinces with higher EHDI had a better 3-year survival (0.93 vs. 0.77 for lower EHDI, P
