A generalizable cross-continent prediction of esophageal squamous cell carcinoma using the oral microbiome

Key Points

The aim is to determine if the oral microbiome can predict esophageal squamous cell carcinoma (ESCC) and serve as a non-invasive screening tool.
Analyzed oral microbiome samples from individuals with ESCC and controls
Compared microbiome profiles to identify distinguishing features
Validated findings across different geographical samples
Identified distinct oral microbiome profiles in individuals with ESCC compared to controls
Demonstrated that these microbiome features generalize across unseen samples
Indicated the potential for saliva to be used as a screening tool for ESCC

Abstract

Our results show that the oral microbiome in individuals with ESCC is distinct from controls and that this signal can generalize across unseen samples, suggesting the potential of saliva to serve as a non-invasive screening tool for ESCC.
