Título

Malignant Brain Neoplasms in Brazil: an epidemiological analysis from 2020 to 2023.

Introdução

Malignant brain neoplasms can be divided into: primary - cells from the brain tissue itself initiate anomalous behavior; and secondary - resulting from metastases, mainly from breast, lung, kidney, colorectal and skin cancer. Secondary tumors are the most prevalent in adults, mainly affecting the frontal lobe. Many patients discover the cancer of the primary site through brain metastasis. The main symptoms are Motor deficit, Headache and Drowsiness.

Objetivo

To analyze the epidemiological profile, in relation to the prevalence of cases of malignant neoplasm of the brain, in all regions of the country from January 2020 to November 2023.

Métodos

An ecological, retrospective, quantitative and descriptive study, whose data were taken from searches in the Hospital Information System (SIH/SUS), through the Department of Informatics of the Unified Health System (DATASUS), for the period from January 2020 to November 2023. The variables selected were region, number of hospitalizations, average value of hospitalization, absolute deaths, race/color, gender, age range from 1 to 80 years and mortality rate.

Resultados

52,294 hospitalizations due to malignant brain neoplasms were found in Brazil between January 2020 and November 2023. Regarding the number of hospitalizations, the Southeast had the highest rate, with 23,423 hospitalizations, while the North had the lowest rate, with only 2,137 hospitalizations. The South had the highest average cost of hospitalization, R$: 3,844.51. The Midwest had the lowest investment of R$: 2,906.52. Although the Southeast had the highest number of absolute deaths (3,331 deaths), the North had the highest mortality rate (17.22%). Of the total number of deaths, 52.42% were male and 47.58% were female. The age group with the highest number of deaths were 60 to 69-year-olds (1,766 deaths) and 50 to 59-year-olds (1,468 deaths), while the 15 to 19-year-old age group had the lowest number of deaths (117 deaths). The White race had the highest number of deaths (49.27%) and the race with the lowest number was the Indigenous race (0.17%).

Conclusões

The Southeast had the highest incidence of hospitalizations, possibly due to population density and the wide availability of health services. The North region had the highest mortality rate, despite having the lowest number of hospitalizations. These trends highlight the need for specific public policies in each region, aimed at improving the diagnosis and effective treatment of this cancer, in order to improve clinical and epidemiological outcomes.
