Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of the proposed research is to investigate the molecular mechanisms of racial disparity in Barrett's esophagus (BE), the premalignant lesion of esophageal adenocarcinoma. Specifically, the investigators hypothesize that environmental factors, genetic factors, and potentially gene environment interactions play crucial roles in the observed racial disparity in developing Barrett's esophagus. Patients are recruited through UNC hospitals prior to scheduled esophagogastroduodenoscopy (EGD). Participants complete a questionnaire, have body measurements obtained, and have blood, biopsies, and gastric aspirate collected. Participants also complete a 24 hour pH impedance test.
