BACKGROUND: Worldwide gastric cancer (GC) ranks sixth in incidence and second in mortality among all malignancies. CDX2 has an essential role in the development and maintenance of intestinal differentiation in the gut and ectopic sites such as intestinal metaplasia (IM) of the stomach. SOX2 contributes to the cell lineages normally found in the stomach, suggesting contribution in gastric differentiation.
AIM: The aim of the study was to assess the expression of CDX2 and SOX2 in chronic gastritis (CG) lesions associated with Helicobacter pylori, IM, or dysplasia as well as in intestinal-type GC.
METHODS: Immunohistochemical staining for CDX2 and SOX2 were applied on archival paraffin blocks from 80 CG cases, 40 intestinal-type GC cases, and 10 controls. CG cases were either of non-specific inflammation or associated with H. pylori infection. GC cases were of intestinal-type only, excluding any other type of GC. Control cases were of minimal gastritis, negative for H. pylori, IM, and dysplasia.
RESULTS: CDX2 expression was correlated with CG associated with H. pylori, IM, and dysplasia as well as with more differentiated and less invasive pattern of intestinal-type GC, while SOX2 expression was correlated with CG negative for H. pylori and IM as well as with less differentiated and more invasive intestinal-type GC.
CONCLUSION: Both CDX2 and SOX2 could predict the behavior of CG disease over time and plan the suitable line of treatment and both proteins could be potential targets for novel therapeutic interventions.
