Abstract: Background: Brain tumors are neoplasms originating from various cells of the central nervous system (CNS) or from metastases of other primary cancers. The global incidence is low, around 3 cases per 100,000 people, with 11,000 new cases annually in Brazil. Although rare, they are highly incapacitating and have high morbidity and mortality, with a 5-year survival rate of 37%. Objective: To calculate the prevalence of hospitalizations due to brain neoplasms (primary and metastatic lesions) in the federative regions of Brazil and to compare these prevalences with the mortality rates in these regions over the last 5 years. Methods: The methodology of this study involved data collection from the Hospital Information System (SIH) from January 2019 to December 2023. To calculate prevalence, we used population data from the 2022 census by IBGE. Mortality rates were also obtained from the SIH for the same period. All data were based on the place of residence and year of service. Results: From 2019 to 2023, there were 75,799 hospitalizations due to brain neoplasms in Brazil. The federative region with the highest hospitalization prevalence (per 100,000 inhabitants) was the South (58.68), followed by the Central-West (40.09), Southeast (37.5), Northeast (29.66), and North (21.22) regions. Although the highest prevalence of cases was concentrated in the South, the highest annual mortality rate was in the North (15.32), followed by the Southeast (14.82), Northeast (12.88), South (12.25), and Central-West (12.11). The average mortality rate for hospitalizations due to brain neoplasms in Brazil was 13.60. Conclusion: Brain tumors, while rare, represent a significant public health challenge in Brazil due to their high morbidity and mortality. Between 2019 and 2023, there were 75,799 hospitalizations for brain neoplasms, with the South region having the highest prevalence (58.68 per 100,000 inhabitants) and the North region the lowest (21.22 per 100,000 inhabitants). However, the highest mortality rate was observed in the North (15.32). The national average mortality rate was 13.60, highlighting the need for interventions to improve the diagnosis and treatment of brain tumors, especially in regions with higher mortality, in addition to enhancing healthcare infrastructure.
