Objective:
Our aim was to analyze current research output and potentially predict future trends in neuro-oncological research in Africa by investigating deficits in the field. This study will help us identify which countries are performing well in this field, and which ones face challenges and how to solve them. Therefore, targeted interventions can be applied to overcome these challenges.

Background:
There is evidence that individuals of African ancestry, particularly those residing in Africa, suffer from an unfortunate amount of under-representation in cancer research worldwide.

Design/Methods:
We conducted a systematic computer-based search on the following databases: (PubMed, Scopus, Web of Science, and Embase) for research articles related to the neuro-oncological field in Africa. We aimed to retrieve any article published in the period between 1st January 2000, to 10th  January 2023

Results:
We included 200 eligible articles in our study. The output of neuro-oncological research has been increasing over the past two decades with its peak in 2019. Among the included articles, clinical practice issues constituted the majority (80%), while public health-related topics accounted for 20% of the publications. Regarding the type of central nervous system (CNS) cancer, neuroblastoma was the most common with 26 (13%) articles, meningioma with 21 (10.5%), and glioma with 16 (8%) articles.

Conclusions:
This scoping review reveals an increasing interest in neuro-oncological research in Africa. The findings highlight the need for ongoing efforts to address issues with clinical practice and public health related to CNS cancers in the continent. Future studies should concentrate on filling in knowledge gaps and investigating novel methods for neuro-oncological conditions that affect African populations in terms of prevention, diagnosis, treatment, and management strategies.
