Expression of MMP-2, c-erbB-2 and clinical significance in non-small cell lung cancer / 肿瘤研究与临床

ABSTRACT

Objective To investigate the expression of MMP-2 and c-erbB-2 and evaluate the correlation of clinical pathological parameters in non-small cell lung cancer. Methods Forty-five paraffin-embedded specimens of radical postoperative non-small cell lung cancer was detective for MMP-2 and c-erbB-2 using immunohistochemical method. Results The positive rates of MMP-2 and c-erbB-2 are 57.8 %, 75.6 %, there is a significance between the expression of MMP-2 and lymph node metastases(P =0.006), the expression of c-erbB-2 is related to clinical stage and lymph node metastases (P =0.015, P =0.032), The expression of MMP-2 and c-erbB-2 are related to 5-year survival rate (P =0.002, P =0.003). Conclusion The expression of MMP-2 and c-erbB-2 is significantly related to some clinical parameters and 5-year survival rate.
