Non- Gastric Microbiome Modulates Prooncogenic Responses and Is Associated With Gastric Cancer Risk.

Background And Aims: Although is the most important bacterial carcinogen in gastric cancer (GC), GC can emerge even after eradication. Studies suggest that various constituents of the gastric microbiome may influence GC development, but the role of individual pathogens is unclear.

Methods: Human gastric mucosal samples were analyzed by 16SrRNA sequencing to investigate microbiome composition and its association with clinical parameters, including GC risk.
