Abstract
The data on esophageal and gastric cancers in sub-Saharan Africa are fragmented and not numerous because of the rarity and of the inaccessibility of the diagnostic means. Esophageal cancer has very variable incidences according to the geographical zones there and nutritional and infectious factors are incriminated in its arisen. It reaches young subjects with a preferential siege the average esophagus with ascendancy of squamous cell carcinomas. For gastric cancer, its incidence there is low despite the strong prevalence of Helicobacter pylori infection. As in Western countries, Helicobacter pylori’s gene Cag A is correlated in its arisen there but the low prevalence of strains with multiple EPIYA-C segments might contribute to its low incidence. It affects young subjects more often male with a big ascendancy of adenocarcinoma. The improvement of the diagnostic conditions and the financing of researches are necessary for a better knowledge of the risk and the protective factors of esophageal and gastric cancers in sub-Saharan Africa.
