INTRODUCTION: Microbial dysbiosis has been shown to be involved in various types of gastrointestinal cancers, but there is a dearth of strong studies linking the oral microbiome imbalance with esophageal cancer (EC).
OBJECTIVES: The main objective of the study was to identify the link between oral microbiome and EC.
MATERIALS AND METHODS: Twelve suspected EC and two healthy control patients were recruited. After the histological confirmation of EC, four confirmed EC patient samples and two healthy control samples were subjected to 16S metagenomics study using the Oxford Nanopore Technology sequencing platform.
RESULTS: Species richness of microbial community was higher in the healthy controls followed by diseased plaque, tumor tissue and adjacent tissue. Bacillota, Pseudomonata, Fusobacteriota, Bacteroidota, and Campylobacterota were the major phyla identified in all the groups. Majorly prevalent genera (core microbiome analysis) in all the groups were Streptococcus, Salmonella, Bacillus, Enterococcus, Veillonella, Klebsiella, Clostridioides, Prevotella, Gemella, Selenomonas, Firmicutes, and Proteobacteria followed by Bacteroidetes and Fusobacteria.
CONCLUSION: Our study suggests an association between oral microbiome and EC. The prevalence of same microbial genus in the oral cavity (dental plaque) and tumor tissue depicts a possible link. Our study opens the plausible microbe-based biomarker screening of EC.
