Resumo

Introdução: Segundo a Organização Mundial da Saúde, os Tumores Cerebrais (TC), malignos e benignos, têm incidência crescente em todo o mundo, principalmente naqueles países de baixa e média renda. Objetivo: De acordo com esses dados crescentes em regiões de saúde de baixa renda, este estudo teve como objetivo descrever a epidemiologia dos TC neurocirúrgicos em uma região de saúde de baixa renda no Brasil. Métodos: Trata-se de um estudo de coorte retrospectivo, sendo descritos pacientes que realizaram intervenção neurocirúrgica em um centro de referência em neurocirurgia de alta complexidade no período de 2010 a 2018, com coleta de dados de seus prontuários (idade, sexo, tipo de TC e distúrbio neurológico, pré e pós-operatório). Resultados: Foram avaliados 197 pacientes submetidos a procedimento neurocirúrgico por TC malignos do sistema nervoso central. A média de idade foi de 52,0 anos (±16,9), sendo 53,8% do sexo feminino e 41,5% desses pacientes apresentavam tumor cerebral maligno. Os tumores meníngeos e mesenquimais foram o tipo de tumor cerebral não maligno mais frequente e o astrocitoma foi o tumor maligno mais frequente. Antes da neurocirurgia, 85,8% dos pacientes apresentavam algum distúrbio neurológico. Após isso, o número de pacientes com algum déficit reduziu para 42,6%. Conclusão: Apesar de serem fornecidos dados de uma das regiões mais pobres do Brasil, pode-se concluir que a assistência neurocirúrgica se compara aos países desenvolvidos. Em nossos resultados encontramos uma incidência mundial semelhante de TC, e também uma incidência semelhante de distúrbios neurológicos antes e após a neurocirurgia.

Abstract

Introduction: According to the World Health Organization, Brain Tumor (BT), malignant and benign, have an increasing incidence worldwide, mainly in those low and middle-income countries. Objective: According to these growing data in low-income health regions, this study aimed to describe the epidemiology of Neurosurgical BT in a low-income health region in Brazil. Methods: This is a retrospective cohort study. patients who underwent neurosurgery intervention in a high-complexity neurosurgery reference center from 2010 to 2018, with data collect from its medical records (age, gender, type of BT and neurological disorder, pre- and postoperative) were described. Results: A total of 197 patients who underwent a neurosurgical procedure due to Central Nervous System malignant BT was assessed. The mean age was 52.0 years (±16.9), in which 53.8% were female and 41.5% of those patients had a malignant brain tumor. Meningeal and mesenchymal tumors were the most frequent type of non-malignant brain tumor and astrocytoma was the most frequent malignant tumor. Before neurosurgical procedure, 85.8% of patients had some neurological disorder. After this, the number of patients with any deficit reduced to 42.6%. Conclusion: Despite being given data from one of the poorest regions of Brazil, it can be concluded that neurosurgical assistance is compared to that in developed countries. In our results a similar worldwide incidence of BT, and also a similar incidence of neurological disorders before and after neurosurgery were found.
