Cytokeratin 7 and 20 expression in intestinal metaplasia of the distal oesophagus: relationship to gastro‐oesophageal reflux disease

Abstract

CK7/20 immunoreactivity for patients with intestinal metaplasia of the distal oesophagus without long segment Barrett's oesophagus suggests a heterogeneous group, with an association between Barrett's CK7/20 pattern and gastro-oesophageal reflux disease in both short segment Barrett's and intestinal metaplasia of the gastro-oesophageal junction.
