Current Status and Challenges of Research on Biomarkers of Barrett’s Esophagus in Risk Stratification / 胃肠病学

ABSTRACT

Barrett’s esophagus (BE) is the recognized precancerous lesion and risk factor for esophageal adenocarcinoma (EAC), and has a high miss diagnosis rate and low survival rate when malignantly transformed into EAC, moreover, there are only limited monitoring method and treatment. Therefore, the screening of biomarkers is highly expected, especially the risk stratification biomarkers related to the progression of malignant transformation of BE. Such biomarkers can help to determine early, quickly and accurately the disease process, and guide the stratified management and precise treatment of BE, reduce the malignancy rate and mortality. This article focused on the dynamic evolutionary process of intra‑tumor heterogeneity, and reviewed the current status and challenges of research on BE biomarkers in risk stratification from the genetics, epigenetics and serology perspectives.
