Neuro-oncology access in Sub-Saharan Africa: A literature review of challenges and opportunities

Background: Ensuring equitable access to treatments and therapies in the constantly evolving field of neuro-oncology is an imperative global health issue. With its unique demographic, cultural, socioeconomic, and infrastructure characteristics, Sub-Saharan Africa faces distinct challenges. This literature review highlights specific barriers to neuro-oncology care in the region and explores potential opportunities for enhancing access.

Methods: Predetermined keyword searches were employed to screen titles and abstracts using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses framework. Inclusion criteria were studies published between January 1, 2003, and June 20, 2023, specifically addressing the capacity and challenges of neuro-oncology in the Sub-Saharan African region. The data sources queried were PubMed and Google Scholar. Systematic reviews and meta-analyses were deliberately excluded. All authors conducted independent screening and structured data extraction meticulously.

Results: Our paper identified multiple challenges that impede access to quality treatment for brain tumors. These include constrained resources, insufficient training of healthcare professionals, certain cultural beliefs, and a general lack of awareness about brain tumors, all contributing to delayed diagnosis and treatment. Furthermore, the lack of detailed data on the incidence and prevalence of primary central nervous system tumors impairs the accurate assessment of disease burden and precise identification of areas requiring improvement. However, we discovered that ongoing research, advocacy, enhanced training, mentorship, and collaborative efforts present valuable opportunities for substantial progress in neuro-oncology access.

Conclusions: While we provide a glimpse of the current state, we hope these results will help stimulate dialogue and catalyze initiatives to surmount highlighted obstacles and improve neuro-oncology outcomes across Sub-Saharan Africa.
