Barrett’s esophagus (BE) is the greatest risk factor for esophageal adenocarcinoma, but only a small proportion of patients with BE develop cancer. Biomarkers might be able to identify patients at highest risk of progression. We investigated genomic differences in surveillance biopsies collected from patients whose BE subsequently progressed compared to patients whose disease did not progress.
