Immunohistochemistry (IHC) staining of E‐cadherin and Kaplan–Meier survival plots for overall survival and relapse‐free survival of gastric cancer patients by its status. (a) Typical IHC staining patterns of E‐cadherin (original magnification, ×400). Among 201 patients 21 were E‐cadherin negative and 180 were positive. (b) No statistical significance in the overall survival (P = 0.72) and relapse‐free survival (P = 0.99) was observed between E‐cadherin‐positive and ‐negative groups.
