Resumo

Introdução: O glioblastoma é o tumor maligno primário do sistema nervoso central mais frequente. Ademais, esse tumor possui elevada morbimortalidade. Destarte, é necessário compreender a população que é mais acometida por essa patologia. Objetivo: Analisar o perfil epidemiológico das internações hospitalares por glioblastoma, no Brasil, durante o período de 2012 a 2021. Métodos: Estudo transversal retrospectivo de abordagem quantitativa, com coleta realizada no banco de dados do Sistema de Registro Hospitalar de Câncer (SisRHC).

Abstract

Introduction: Glioblastoma is the most common primary malignant tumor of the central nervous system. Furthermore, this tumor has a high morbidity and mortality rate. It is therefore necessary to understand the population that is most affected by this pathology. Objective: To analyze the epidemiological profile of hospital admissions for glioblastoma in Brazil between 2012 and 2021. Methods: A retrospective cross-sectional study with a quantitative approach, with data collected from the Hospital Cancer Registry System (SisRHC) database. Results: 13,764 cases of hospitalization for glioblastoma were found, of which 7,927 were male and 5,756 were female. The approximate prevalence was 6.04 per 100,000 inhabitants. However, the geographical distribution was heterogeneous between the Brazilian Federative Units (FU). Approximately 73.9% of patients with this pathology were over 50 years old. Conclusion: Brazil has a prevalence similar to that found in other countries. Furthermore, the distribution among the UFs was mainly due to restricted access to neurology and neurosurgery services. Thus, a predominance of male cases was observed to the detriment of female cases. The incidence of glioblastomas increases after the age of 50, with a peak between 55 and 65. In addition, it was found that there is a higher prevalence among white people when compared to other ethnic groups. In terms of pathology, the frontal, parietal and temporal lobes were the most frequent primary locations. As for treatment, the most widely used approach in the country is radiotherapy in monotherapy and the most common outcome was death.
