Abstract
Rare glial, neuronal and glioneuronal tumours in adults form a heterogeneous group of rare, primary central nervous system tumours. These tumours, with a glial and/or neuronal component, are challenging in terms of diagnosis and therapeutic management. The novel classification of primary brain tumours published by the WHO in 2021 has significantly improved the diagnostic criteria of these entities. Indeed, diagnostic criteria are nowadays multimodal, including histological, immunohistochemical and molecular (i.e., genetic and methylomic). These integrated parameters have allowed the specification of already known tumours but also the identification of novel tumours for a better diagnosis.

Abstract
INTRODUCTION Primary central nervous system (CNS) tumors represent an important and growing cause of worldwide morbidity and mortality. There are global variations in the reported case burden of CNS tumors, with high-income countries reporting a higher incidence of cases than low- and middle-income countries. Variations are attributed to differences in access to care, diagnostic capacity, risk exposure, and under-reporting in LMICs. This study aims to review existing literature on the distribution of primary CNS tumors and neuro-oncologic care, and the contribution of scientists and institutions to neuro-oncologic research across 18 East African countries over the last 5 decades. METHOD A search was conducted using OVID Medline and PubMed databases to identify relevant East African neuro-oncologic studies published over the last 50 years. RESULTS The authors reviewed 36 neuro-oncology articles published across 8 of 18 East African countries. Kenya represented the highest number of published articles; ten countries queried yielded zero publications. A total of 2006 cases from all age groups were represented in published literature consisting of a wide spectrum of CNS tumors. One-third of reported cases were pediatric. Meningioma formed the largest proportion (43.3%) followed by glioma (33.7%). Sixty-seven percent of publications gave an overview of clinical care received by patients with most patients not receiving comprehensive neuro-oncologic care. CONCLUSION The modest collection of neuro-oncology publications from East Africa shows that the case diversity of primary CNS tumors in East Africa is comparable to the rest of the world. There is, however, poorer access to neurosurgical care and adjuvant therapy. Multidisciplinary efforts from clinicians, researchers, and healthcare agencies are needed to quantify and address the requisite neuro-oncology needs in this region.
