Barrett Esophagus Early Detection Study

The Barrett Esophagus Early Detection Study was initiated in 2006, with the primary goal of identifying a practical blood-based biomarker to distinguish persons with Barrett esophagus (BE) from those without it. This BE case-control study is being conducted at the Walter Reed National Military Medical Center in Bethesda, Maryland, among Barrett Esophagus Registry patients and non-BE patients who have endoscopies in the Gastroenterology Clinic.
