| Abstract: Intratumoral bacteria, as an important component of the tumor microenvironment, are associated with tumor initiation and progression. This review summarizes the origins, diversity, and heterogeneity of intratumoral bacteria, evaluates the technical features and limitations of major detection methodologies, and outlines the pro-tumorigenic mechanisms attributed to these microorganisms. It further highlights the roles and mechanisms of intratumoral bacteria at different stages of tumor metastasis, including epigenetic regulation, exosome-mediated effects, bacterial phenotypic features, tumor angiogenesis, metabolic reprogramming, and immune modulation. Additionally, the potential clinical value of intratumoral bacteria in tumor diagnosis, prognosis assessment, and treatment is discussed, which may deepen the understanding of their biological functions and promote their application in precision oncology. |
