Distinct Oral-associated Gastric Microbiota and Communities for Spatial Microbial Heterogeneity in Gastric Cancer

Abstract

Importance: Our study highlights the roles of the oral-associated microbiota in the upper third of gastric cancer (GC).We showed that the oral-associated species and were correlated with overall survival. In addition, oral-associated species may serve as noninvasive screening tools for the management of GC and an independent prognostic factor for -negative GCs.
