The Gastric Microbiome and Its Influence on Gastric Carcinogenesis: Current Knowledge and Ongoing Research

Hematol Oncol Clin North Am. 2017 Jun;31(3):389-408. doi: 10.1016/j.hoc.2017.01.002. Epub 2017 Mar 22.

Abstract

Gastric malignancies are a leading cause of cancer-related death worldwide. At least 2 microbial species are currently linked to carcinogenesis and the development of cancer within the human stomach. These include the bacterium Helicobacter pylori and the Epstein-Barr virus. In recent years, there has been increasing evidence that within the human gastrointestinal tract it is not only pathogenic microbes that impact human health but also the corresponding autochthonous microbial communities. This article reviews the gastrointestinal microbiome as it relates primarily to mechanisms of disease and carcinogenesis within the upper gastrointestinal tract.

Keywords: EBV; Gastric cancer; Gastric microbiome; Helicobacter pylori; Microbial identification.
