Neutrophil-Lymphocyte Ratio May be Used as a Biomarker for Predicting Progression of Barrett's Esophagus to Esophageal Adenocarcinoma: A Retrospective Cohort Study.

Aims: This study aims to investigate the correlation between the neutrophil-lymphocyte ratio (NLR) and advancing stages of Barrett's esophagus (BE) to esophageal adenocarcinoma (EAC).

Methods And Results: A retrospective cohort of patients diagnosed with BE and EAC were analyzed. Cases were categorized into four groups according to their histological diagnosis: non-dysplastic BE (NDBE), low-grade dysplasia (LGD), high-grade dysplasia (HGD), and EAC.
