N2 - Purpose of Review: Gastric cancer (GC) represents one of the leading causes of cancer-related deaths worldwide. The prevalence of GC among the younger population has been increasing in recent years, and the latter is associated with late detection and advanced disease status. The factors involved in the development of GC have been the focus of investigation in the past few years; yet no consistent conclusions or preventative solutions have been suggested. This scoping review aims to explore and report on research studies conducted to investigate the association between GC, the gut microbiome, and nutritional habits. Recent findings : Using a predefined protocol in compliance with the PRISMA guidelines, a search was conducted on four separate databases including Google Scholar, Cochrane Library, ProQuest, and PubMed to investigate the association between GC, microbiome, and nutrition. A total of 1219 articles were identified through this process. Forty-three articles met the initial screening criteria and following full-article analysis, and 10 articles met the full inclusion criteria and were included in the current review. The results of the study support that there are differences in the gut microbiota between GC patients and healthy controls and that GC patients may have increased microbiota richness and lower diversity compared to healthy controls. In addition, the detection of pre/early GC may be possible through the analysis of the microbiota using fecal sampling. Nutritional habits, probiotics, and antibiotics may also play an important role in affecting GC development. Summary: Preliminary studies support a role for the gut microbiota in developing GC. Yet, the lack of sufficient randomized controlled studies investigating the association between GC, the gut microbiota, and nutritional habits demonstrates the need for further clinical research to develop preventative strategies that will aim to reduce the increased incidence of GC among all age groups including younger populations.
