Abstract:
Purpose To analyze the MMP-9,MMP-13,HIF-1α expression in lung adenocarcinoma tissue and to explore the relationship with clinical pathologic features,EGFR mutation and prognosis of the patients.Methods The expression of MMP-9,MMP-13,HIF-1α in 629 cases of lung adenocarcinoma were detected by using immunohistochemical of SP method.50 cases of normal tissue adjacent to carcinoma and 50 cases of pneumonia pseudotumor hyperplasia tissues were selected as controls.629 patients with lung adenocarcinoma were detected by real-time fluorescence quantitative PCR and all of them were followed-up.Results The MMP-9,MMP-13,HIF-1α expression in lung adenocarcinoma tissues were higher than controls (P ＜ 0.001).The MMP-9 expression was correlated with lymph node metastasis and the size of the tumor (P ＜ 0.05).The MMP-13 expression was correlated with smoking history,TNM stage,lymph node metastasis and the size of the tumor (P ＜0.05).The HIF-1α expression were correlated with smoking and lymph node metastasis.Statistically significant differences were found in all these above groups (P ＜ 0.05).But the expression of all has nothing to do with the EGFR mutation (P ＞0.05).The Kaplan-Meier survival analysis results showed that MMP-9,MMP-13,HIF-1α positive expression groups of 12,24 and 36 months cumulative survival were significantly lower than the negative expression groups.COX multiple factor analysis results showed that EGFR mutation,the expression of MMP-9,MMP-13,HIF-1α,tumor size,TNM stage were independent risk factors for the development of lung adenocarcinoma patients living conditions.Statistically significant differences were found in these groups (P ＜0.05).Conclusion MMP-9,MMP-13,HIF-1α are overexpressed in lung adenocarcinoma tissues,and its expression are associated with lymph node metastasis,but has nothing to do with EGFR mutations.Patients with positive expression of MMP-9,MMP-13,HIF-1α and with no EGFR mutation have lower survival rates,and they are independent risk factors for the development of lung adenocarcinoma patients living conditions.
