CDH1 and non-small cell lung carcinoma: Here we investigated expression of p120ctn, E-cadherin and vimentin in 78 human non-small cell lung cancer (NSCLC) samples by immunohistochemistry and found that p120ctn membrane expression positively correlated with E-cadherin expression (P<0.001) and negatively correlated with vimentin expression and lymph node metastasis (P<0.05).
