Abstract:

Objective To investigate the expressions of KAI1 gene,tissue inhibitor 1 of metalloproteinase (TIMP-1) and matrix metalloproteinase 9 (MMP-9) in non-small cell lung cancer (NSCLC) and their correlations with clinicopathologic features of NSCLC. Methods The expressions of KAI1,TIMP-1 and MMP-9 in 73 specimens of NSCLC tissues,51 specimens of corresponding adjacent tissues and 13 specimens of non-cancerous lung tissue were determined by immunohistochemistry. Their correlations with clinicopathologic features were analyzed by χ2 test and Pearson analysis. Results In 73 specimens of NSCLC tissues and 64 cases of corresponding adjacent and non-cancerous lung tissues,the positive rates of KAI1 and TIMP-1 were 39.7%,74.0% and 90.6%,37.5% with statistical significance (P<0.05),and the positive rates of MMP-9 were 79.4%,67.1% without statistical significance (P>0.05). The expression of KAI1 was correlated to TNM stage,lymph node metastasis,histologic subtype and differentiation with statistical significance (P<0.05),and the TIMP-1 and MMP-9 were correlated to TNM stage and lymph node metastasis (P<0.05),but they were not correlated to age and sex. The expression of KAI1 was negatively correlated with the expressions of TIMP-1 and MMP-9 (r=-0.463 7,-0.344 5,P<0.05). Conclusions The KAI1,TIMP-1 and MMP-9 are related to the development of lung cancer. The combination determination of them will be the important prognosis reference indicator for the occurrence and development of NSCLS.
