摘要

Gastric cancer (GC) ranks among the most prevalent malignant neoplasms globally and is one of the leading causes of cancer-related mortality. The gastric microbiota, as a crucial component of the human microecosystem, plays a pivotal role in maintaining human health through its ecological balance. In recent years, with the advancement of technologies such as metagenomics, the dysbiosis of gastric microbiota has increasingly become a focal point of research, particularly in understanding its role in the initiation, progression, and treatment of GC. This review elucidates the current understanding of the roles played by gastric microbiota and their metabolic products in the progression of GC. Additionally, it summarizes and prognosticates the translational value and clinical significance of gastric microbiota in the diagnosis, prognosis, and treatment of GC. The gastric microbiota assumes a dual role in the progression and treatment of GC. Further in-depth studies on the interactions and mechanisms between gastric microbiota and the host represent an emerging and valuable area in the field of GC research.
