Abstract
Burkitt lymphoma (BL) is a form of non-Hodgkin's lymphoma (NHL) that is characterized by high aggressiveness and arises from the germinal center of B cells. The prevalence of BLin adulthood is less than 5%. However, it encompasses 40% of all childhood NHL. Diffuse large B-cell lymphoma (DLBCL) is the most common lymphoma. It accounts for approximately 25% of all NHL cases worldwide. The differentiation between BL and DLBCL is more clear in theory than in daily practice. However, it is important because it implies different treatments. Compared to the other indolent small cell lymphomas, DLBCLs and BLs show higher Ki-67 index values. The Ki-67 levels in DLBCL typically range from 40% to 90%, while BL has a high Ki-67 positivity, nearing 100%. The aim of this article is to explore and review the function of Ki-67 as a differential marker for BL and DLBCL. An all-language literature search was conducted on MEDLINE, Cochrane, Embase, and Google Scholar until March 2024. The following search strings and Medical Subject Heading (MeSH) terms were used: "Ki-67," "Burkitt lymphoma," and "diffuse large B-cell lymphoma." We comprehensively reviewed the literature on BL, DLBCL, and the Ki-67 marker.
