Oral microbiome research in cancer detection

Overview

Researchers at Yonsei University have identified a link between oral-gut microbial transmission and the presence of gastrointestinal cancers. By utilizing a mouth-to-feces (MF) index through 16S ribosomal RNA sequencing, the study found that oral microbes colonize the digestive tracts of patients with gastric and colorectal cancers at significantly higher rates than healthy individuals or those with metabolic disorders.

In a study led by Jihyun F. Kim and published in the journal Cell Host & Microbe, researchers analyzed 507 volunteers to identify distinct microbial signatures. The findings suggest that patterns in oral microbial communities differ based on health status, potentially allowing saliva-based screening to serve as a less invasive alternative to traditional stool samples for detecting gastrointestinal carcinomas. The research indicates that the MF index remains a consistent metric even when accounting for factors such as alcohol consumption, exercise, and body mass index.
