Introduction: Mortality due to central nervous system (CNS) neoplasms is one of the leading causes of death in the pediatric population. Although Brazil has experienced a general decline in pediatric mortality from CNS neoplasms over the past decade, this trend has not been consistent across all regions of the country.
Methods: This study analyzed trends and regional variations in pediatric mortality from CNS neoplasms using data from the Mortality Information System (SIM) and the Brazilian Institute of Geography and Statistics (IBGE). Mortality rates among individuals aged 0 to 19 were examined and stratified by sex, race, and federal unit.
Results: CNS neoplasms accounted for 27.3% of all deaths from neoplasms in the pediatric population. An overall reduction in mortality was observed, with the Southeast and Midwest regions showing the most significant declines, while the South experienced a less pronounced reduction. Mortality was more prevalent among males, individuals of white race, and the 5 to 9-year age group—contrasting with international findings that report higher mortality in children under 5 years of age. The data also revealed a trend of decreasing mortality with increasing age.
Conclusion: Regional disparities in mortality may be associated with differences in diagnostic capabilities and access to treatment. The age-related discrepancies between Brazilian and international data may reflect regional demographic dynamics. These findings highlight the ongoing need for improvements in early diagnosis, specialized care, and health education to further reduce CNS neoplasm mortality rates in Brazil.
