Abstract

The morbidity and mortality of gastrointestinal (GI) malignancies are among the highest in the world, posing a serious threat to human health. Because of the insidious onset of the cancer, it is difficult for patients to be diagnosed at an early stage, and it rapidly progresses to an advanced stage, resulting in poor treatment and prognosis. Fusobacterium nucleatum (F. nucleatum) is a gram-negative, spore-free anaerobic bacterium that primarily colonizes the oral cavity and is implicated in the development of colorectal, esophageal, gastric, and pancreatic cancers via various intricate mechanisms. Recent development in novel research suggests that F. nucleatum may function as a biomarker in GI malignancies. Detecting the abundance of F. nucleatum in stool, saliva, and serum samples of patients may aid in the diagnosis, risk assessment, and prognosis monitoring of GI malignancies. This editorial systematically describes the biological roles and mechanisms of F. nucleatum in GI malignancies focusing on the application of F. nucleatum as a biomarker in the diagnosis and prognosis of GI malignancies to promote the clinical translation of F. nucleatum and GI tumors-related research.

Keywords: Gastrointestinal malignancies, Fusobacterium nucleatum, Biomarker, Diagnosis, Prognosis

Core Tip: Gastrointestinal (GI) malignancies are characterized by high morbidity and mortality. Early diagnosis of GI malignancies is crucial for disease intervention and treatment. Numerous studies have shown that Fusobacterium nucleatum (F. nucleatum) is closely related to the development of various GI malignant tumors. This paper discusses the mechanism of F. nucleatum in promoting the progression of GI tumors, elaborates its clinical value as a diagnostic and prognostic biomarker, and provides ideas for the development and research of novel biomarkers for GI malignancies.
