Sickle cell trait is not associated with endemic Burkitt lymphoma: An ethnicity and malaria endemicity-matched case–control study suggests factors controlling EBV may serve as a predictive biomarker for this pediatric cancer
(International Journal of Cancer, 2013)Endemic Burkitt lymphoma (eBL) is associated with Epstein–Barr virus (EBV) and Plasmodium falciparum coinfections. Malaria appears to dysregulate immunity that would otherwise control EBV, thereby contributing to eBL ... -
