Core Tip

Core tip: Barrett’s esophagus (BE) is known to be a precancerous state of adenocarcinoma will become common in Asian countries, therefore, it is important to establish a high-risk group or strategy for screening or follow-up of BE. We present here the results of univariate and multivariate analysis to identify variables associated with dysplasia of BE. p53 expression in immunohistochemistry was associated with dysplasia, and Helicobacter pylori infection and high diastolic blood pressure may act as protective factors against dysplastic change of BE. These three factors may be candidates to establish a high-risk group for esophageal adenocarcinoma.
