Explore the latest research on gastric microbiome and its role in gastric cancer development in this 26-minute conference talk from the 2022 Gastric Cancer Summit. Delve into compositional differences in the gastric microbiome with and without H. pylori, and examine the distribution of bacterial DNA integrations in gastric adenocarcinoma. Investigate how the presence of CagA alters the gastric microbiota composition in H. pylori-infected gerbils. Learn about the distinct gastric microbiota profiles in chronic gastritis and gastric carcinoma, and understand how gastric microbial dysbiosis is associated with gastric cancer across various stages of carcinogenesis. Explore the correlation strengths of gastric cancer-enriched and depleted bacteria with disease progression. Examine the effects of intestinal Helicobacter infection on H. pylori-induced gastric injury and the impact of iron deficiency on H. pylori-induced dysplasia. Gain insights into the "axis of evil" in H. pylori-induced gastric cancer and consider future research directions in this field presented by Dr. Richard Peek from Vanderbilt University.
