Glioblastoma management in low and middle-income countries; existing challenges and policy recommendations

Abstract

Glioblastomas (GBM) are the most prevalent malignant CNS tumors globally, affecting about 3.19 per 100,000 people. The standard of care of GBM management includes surgical resection followed by radiotherapy and/or chemotherapy owing to the high recurrent rates. Despite the advances in neurosurgical practice and brain cancer research, low- and middle-income countries (LMICs) did not benefit greatly from these advances compared to high-income countries (HICs). First, the case ascertainment is low in LMICs, which contributes to a lower than actual disease burden and delayed presentation of the tumors with a worse prognosis. Second, GBM treatment is expensive; unregulated radiation and chemotherapy costs can expose the patients to financial hardships and lead to treatment discontinuation. Third, the lack of trained neurosurgical workforce in poor resource settings in LMICs further complicates the situation. Fourth, radiation therapy and chemotherapies are expensive and unavailable in many poor-resource settings in LMICs. Fifth, LMICs suffer from a weak infrastructure especially with low numbers of prepared ORs, laboratories, and advanced imaging techniques. In the present article, we highlight the major challenges of GBM management and further propose solutions for governments and health policy makers to improve GBM care in LMICs.
