Abstract
Background Central nervous system (CNS) tumors are a significant cause of morbidity and mortality in sub-Saharan Africa (SSA). To date, no large-scale efforts have focused on brain tumor genetics within this region. This study aimed to assess and map the current neuro-oncology capacity in SSA, including workforce availability and existing services for brain tumor registries and biobanks. The results represent the final analysis representing respondents from 70 healthcare institutions.
Methods This cross-sectional study utilized an online survey to collect data from healthcare professionals involved in CNS tumor care across SSA through the Society for Neuro-Oncology SSA (SNOSSA). The survey gathered information on the availability of neuro-oncology practitioners, neuropathology and molecular diagnostic capacity, brain tumor management, cancer registries, and biobanking of specimens. Purposive sampling was used to identify participants, with the questionnaire provided in English, French, and Swahili.
Results A total of 145 respondents from 22 countries and 70 healthcare institutions participated. Among the 70 institutions, neurosurgery was available in 89%, anatomic pathology in 74%, and medical oncology in 71%. For radiologic evaluation, 64% of institutions reported having both CT and MRI, while 17% had CT only. Molecular testing through IHC or NGS was available in 46% of institutions. Multidisciplinary tumor boards for CNS cases were present in 86% of institutions. General cancer registries were available in 66% of institutions, while 29% had brain tumor-specific registries, and 10% maintained brain tumor biorepositories.
Conclusion This study provides a comprehensive summary of the neuro-oncology capacity in SSA. Next steps are to reach out to institutions who have registries and determine what data are being collected, with the hopes of defining a set of common elements to expand registry efforts across SSA. Similarly, to reach out to institutions that have ongoing brain tumor biobanks and CT/MRI capacity to determine what infrastructure exists.
