摘要
Objective: To investigate the expression of p120ctn in non-small-cell lung cancer (NSCLC) and its relationship with clinicopathological factors and prognosis. Methods: p120ctn expression was tested by immunohistochemistry for 80 tumors from patients with non-small-cell lung cancer. Correlations were investigated between p120ctn immunostaining in primary tumors and clinicopathological characteristics and survival. Results: Abnormal expression of p120ctn was found in 68/80(85%) tumors in which 43 cases had cytoplasmic staining. Abnormal staining of p120ctn was related with high TNM stage (P=0.003) and nodal metastasis (P=0.024). However, there was no correlation between altered expression with poor differentiation and histological type. According to Kaplan-Meier survival estimate, the expression of p120ctn was related to the poor survival (P=0.015) of patients. A Cox regression analysis revealed that p120ctn expression was a significant independent factor in the prediction of survival for patients with non-small-cell lung cancer (P=0.008). Conclusion: altered expression of p120ctn was found in non-small-cell lung cancers and was correlated with lymph node metastasis and prognosis. From a practical point of view, the expression of p120ctn can be of prognostic value for patients with non-small-cell lung cancer.
