CDH1 and metastatic neoplasm: Although a high frequency of cadherin expression was observed in metastatic tumors and lymph node metastases, no significant correlation was found between these proteins in primary metastatic tumors and their corresponding lymph node metastases (E-cadherin: r = 0.253; p = 0.327; N-cadherin: r = 0.089; p = 0.733).
