A recent meta‐analysis comprising 33 retrospective studies including 7353 breast cancer patients evaluated the association of E‐cad and OS, DFS and clinicopathologic factors in breast cancer.44 In this study, reduced E‐cad expression on membrane was significantly associated with OS (hazard ratio [HR] 1.57, 95% confidence interval [CI] 1.17‐2.10) and DFS (HR 1.37, 95% CI 1.07‐1.75). The gene discussed is CDH1; the disease is breast carcinoma.
