Abstract
Introduction: Encephalon malignant neoplasms represent about 2% of all malignant tumors worldwide, mainly in the brain. They are classified in primary forms, originating from encephalic tissue, arranged in benign and malignant, and in secondary forms (metastatic representation).

Objective: Evaluate the incidence of hospitalizations and deaths by encephalon malignant neoplasms in
Piauí-Brazil per year of notification, age, sex and race, between January 2014 and March 2023.

Method: This is a transversal, retrospective and quantitative study. The data was collected on the Hospital Information System (SIH/SUS) and the variables selected were: sex, age, and autodeclared race. The Excel software was used to table and evaluate the data. Results: It was evaluated the total of 1935 hospitalizations and 179 deaths by encephalon malignant neoplasm, being the apex of cases in 2021 (258) and 2022 (32), respectively. In relation to age, the most affected were 50 to 59 year-olds, with 295 hospitalizations (15,25%) and 37 deaths (26,67%). On hospitalizations by the pathology, there was a
predominance of males with 995 cases (51,42%), on deaths there was no specific sex predominance. The race that most predominated was the mixed race, with 1584 hospitalizations (81,86%) and 143 (79,89%) deaths.

Conclusion: The epidemiological evaluation evidenced that the most affected by hospitalizations and deaths were the mixed race people from ages 50 to 59, with a predominance of male hospitalization. This research is important to group and improve resources to reduce the incidence of deaths.
