CDH1 and metastatic malignant neoplasm in the lymph nodes: Multivariate analysis further verified that E-cadherin expression, like lymph node metastasis (LNM), was an independent predictor of shorter DFS (HR = 0.117, 95%CI = 0.022–0.619) and OS (HR = 0.096, 95%CI = 0.012–0.790) of early-stage SCC patients.
