PURPOSE Central Nervous System (CNS) tumors pose a substantial health problem. Although data on specific time periods and regions of Africa has been previously reported, no study has yet to provide a systemic review on the frequency of CNS tumors for the entire continent of Africa. This study aims to analyze the frequency of CNS tumors in Africa from 1960 to 2017. METHODS A comprehensive literature search on CNS tumors in Africa was performed using multiple online scientific databases. The following keywords were queried in combination with the phrase “CNS tumors in Africa”: incidence, frequency, epidemiology, prevalence, brain, and cancer. A total of 26 articles met the inclusion criteria. Each selected article reported incidence and mortality rates from different regions of Africa between 1960 to 2017. SPSS21 statistical software was used to analyze the data. RESULTS Nigeria, Egypt, and Uganda were found to have the highest incidence of CNS tumors in Africa. Total incidence was 5902, the majority were males, 3190 with mean rate 122.67 (95% CI: 29.27, 216.07) compared to females, 2501 with a mean rate of 96.19 (95% CI: 26.24, 166.15). The most common CNS tumors found were astrocytoma (24.70%), meningioma (22.22%), pituitary adenoma (8.4%), medulloblastoma (4.26%), craniopharyngioma (4.07%), and other not specified (25.17%). CONCLUSION Given the large population of Africa, the reported total incidence may be underestimated when compared to other continents due to the lack of a central brain tumor registry in Africa. Comprehensive knowledge of CNS tumors in Africa is critical to research and the entire healthcare system.
