CLDN6 and cervical squamous intraepithelial neoplasia: Since EACs have an extensive genetic overlap with the CIN subtype of GAC [32], to which most of the tumors with high CLDN6 expression belonged in our study, this finding strongly correlates to the Dwivedi results and also implicates that CLDN6-enriched subgroups of EAC and GAC will have a similar poor prognosis due to their similar genetic profile.
