Abstract: Gastric cancer is a common clinical tumor, and its incidence and mortality rates rank among the top of malignant tumors. Helicobacter pylori (Hp) is an important carcinogenic factor for gastric cancer. Studies have found that in addition to Hp, other microorganisms in the stomach also play a key role in the progression of gastric cancer. The composition and diversity of the gastric microbiota vary significantly under different gastric disease conditions, which may affect the progression of gastric cancer. Hp can induce gastric epithelial inflammation and oxidative stress through various virulence factors, thereby promoting the occurrence of gastric cancer. Non-Hp microorganisms can be involved in the process of gastric cancer through pathways such as metabolic changes and immune regulation. In recent years, with the development of high-throughput sequencing technology, the complexity of gastric microbiota has gradually been revealed, which provides new insights for the early warning and intervention of gastric cancer. This article comprehensively review the role of gastric microbiota in the progression of gastric cancer.
