Gastroenterology society guidelines recommend endoscopic surveillance as a means to detect early stage cancer in Barrett’s esophagus. However, the incidence of esophageal adenocarcinoma in Western countries continues to increase, suggesting that this strategy may be inadequate. Current surveillance methods rely on the endoscopist’s ability to identify suspicious areas of Barrett’s esophagus to biopsy, random biopsies, and on the histopathologic diagnosis of dysplasia. This review highlights the challenges of using dysplasia to stratify cancer risk and addresses the development and use of molecular biomarkers and in┬ávivo molecular imaging to detect early neoplasia in Barrett’s esophagus.
