Abstract

Introduction: Malignant brain tumors are among the most complex neoplasms in medicine. They include neoplasms such as glioblastomas, astrocytomas, and primary lymphomas. In Chile, their incidence has been lower compared to other countries in the region. However, between 1993 and 2008, Chile experienced one of the highest increases in mortality due to this cause, accompanied by a low proportion of diagnostic confirmation. Objective: To determine the hospital discharge rate (HDR) for malignant brain tumors in Chile between 2020 and 2023. Methodology: Observational, descriptive, and cross-sectional study. Data were obtained from DEIS-MINSAL and INE. Results: A total of 5,334 hospital discharges were recorded during the period. Males across all age groups had a higher HDR than females, with 8.51 and 6.69 cases per 100,000 average population, respectively. The 65–79 age group in both sexes was most frequently hospitalized for this cause. The most common tumor location was the brain, excluding lobes or ventricles (32.2% of cases). Discussion: Although the HDR in Chile remained stable between 2020 and 2023, it decreased among men while increasing among women. Evidence suggests that high estrogen levels may act as a protective factor against glioblastoma and have been associated with tumors showing a better treatment response. Conclusion: This study provides an epidemiological update on malignant brain tumors in Chile, describing their hospital burden based on demographic, clinical, and healthcare-related variables.
