EPIDEMIOLOGICAL PROFILE OF PEDIATRIC MALIGNANT ENCEFALIC NEOPLASMS IN BAHIA

Introdução

Malignant neoplasms of the brain (MNB) in children are the second most common type of cancer in children and adolescents, after leukemias. These tumors can be located in different regions of the brain and spinal cord, and can vary in terms of aggressiveness, prognosis and treatment. Therefore, analyzing the morbidity profile of patients with this condition in the state of Bahia is crucial in order to understanding the characteristics of the affected population and discerning possible associated risk factors.

Objetivo

To analyze the epidemiological profile of pediatric brain tumors in Bahia in individuals up to 14 years of age, investigating factors related to these tumors.

Método

This is an ecological study, based on the collection of information on malignant neoplasms of the brain, contained in the SUS Hospital Information System (SIH/SUS), included in the DATASUS platform. Data from the state of Bahia were analyzed, referring to hospitalizations according to age group (1 to 14 years), sex and color, from January 2019 to December 2023.

Resultados

Analysis of the data on MNB, during the period 2019-2023, in the range of 1 to 14 years, found a total of 2612 notified cases, with a higher prevalence in the 5-9 age group, with 1119 cases (42.9%), followed by 1-4 years, 875 (33.5%), 10-14 years, 618 (23.6%). In terms of gender, the majority of cases affected boys, 1440 (53.4%), compared to 1255 females (46.6%). In addition, with regard to the color criterion, brown individuals prevailed with 967 cases (37%). Furthermore, there was a regularity of annual cases, with 2021 standing out slightly, with 566 cases (21.7%).

Conclusão

The results indicate a slight predominance of cases of malignant neoplasms of the brain in boys, with no significant difference between the sexes. In addition, the age group with the highest prevalence of individuals was between 5 and 9 years, corresponding to Middle childhood. Finally, the higher numbers of brown people confirm the predominant ethnicity of Bahia and the existence of genetic discrepancies. These results are crucial to understanding the characteristics and needs of the population, in order to advise health programs aimed at prevention and effective treatment of the condition, given that cases of the pathology are regular.
