Oral and intestinal flora translocation and tumor development.
Abstract: Cancer metastasis is the leading cause of death in patients. In recent years, there has been a growing recognition of the role of tumor-associated microflora in tumor metastasis. The connection between oral and gut microflora and the tumor microenvironment has also been extensively studied. The migration of oral and gut microflora is closely associated with tumor development. Although there is awareness regarding the significant impact of microbial communities on human health, the focus on their relationship with host organisms, particularly those related to tumor-associated microflora, remains inadequate. As an integral part of the body, the host microflora is crucial for regulating the cancer risk and preventing tumor recurrence. The oral-gut axis plays an indispensable role in human immunity, and many types of cancers, such as colorectal, pancreatic, and breast, are significantly influenced by their internal microbial communities. However, further exploration into the mechanisms underlying the role of the intratumoral microflora in cancer is necessary to achieve a comprehensive understanding. We have summarized and analyzed related articles in PubMed. This article reviews the impact of the oral-gut axis on the human immune system, explores the relationship between the translocation of the oral and intestinal flora and the tumor microenvironment, analyzes the specific mechanisms involved in the translocation of the oral and intestinal microflora during the evolution and progression of tumors, and elaborates on the correlations between the occurrence and development of tumors and the changes in the microflora. Finally, a summary of these abovementioned points is provided.
