Abstract

Fusobacterium nucleatum (F. nucleatum) is a Gram-negative anaerobic bacterium that plays a key role in the development of oral inflammation, such as periodontitis and gingivitis. In the last 10 years, F. nucleatum has been identified as a prevalent bacterium associated with colorectal adenocarcinoma and has also been linked to cancer progression, metastasis and poor disease outcome. While the role of F. nucleatum in colon carcinogenesis has been intensively studied, its role in gastric carcinogenesis is still poorly understood. Although Helicobacter pylori infection has historically been recognized as the strongest risk factor for the development of gastric cancer (GC), with recent advances in DNA sequencing technology, other members of the gastric microbial community, and F. nucleatum in particular, have received increasing attention. In this review, we summarize the existing knowledge on the involvement of F. nucleatum in gastric carcinogenesis and address the potential translational and clinical significance of F. nucleatum in GC.

Keywords: Fusobacterium nucleatum; Gastric microbiota; Gastric cancer; Preneoplastic changes; Prognosis

Core Tip: Fusobacterium nucleatum (F. nucleatum) plays a key role in the development of oral inflammatory diseases and is a member of the oral microbiota. Recently, however, F. nucleatum has been associated with colorectal cancer and several other malignancies, including gastric cancer (GC). In particular, F. nucleatum has been associated with patient outcomes, suggesting its role in clinical practice. In this review, we summarize the current knowledge on the potential role of F. nucleatum in the development and progression of GC from a basic and translational perspective and highlight its potential therapeutic relevance.
