Histopathological subtypes and topographical subsites of gastric cancer in Sub-Saharan Africa: a scoping review

Although the reviewed studies encompassed diverse regions within SSA, the lack of prospective designs and the concentration of data from only a few countries limit broader applicability. Interestingly, early-onset gastric cancer in these studies predominantly exhibited the intestinal subtype-contrasting with the diffuse subtype commonly reported in Asian and Western studies. These findings highlight the need for regionally representative, prospective research to better scrutinize gastric cancer subtypes, subsites, and epidemiological patterns across the continent.
