Abstract:
Objective To investigate the gene mutation of epithelial growth factor receptor(EGFR) and the expressions of hu‐man epiderma1 growth factor receptor 2(HER‐2) and vascular endothelial growth factor(VEGF) in lung adenocarcinoma and their relationships with the clinical pathological factors .Methods ARMS‐PCR method was used to detect the gene mutation of EGFR in 49 lung adenocarcinoma specimens and 10 normal tissue specimens .Immunohistochemical method was also used to detect the ex‐pressions of the HER‐2 and VEGF in them .Results (1) The mutation rates of EGFR and the positive rates of HER‐2 and VEGF in lung adenocarcinoma were significantly higher than those in the normal tissues(P< 0 .01) .(2) The occurs of EGFR mutation were correlated with sex and the smoking habit(P<0 .05);but not correlated with age ,the size of tumor ,differential ,lymph nodes metastasis ,TNM stages and pleural invasion(P>0 .05) .The HER‐2 and VEGF protein expressions in lung adenocarcinoma were correlated with differential ,the size of tumor ,TNM stages ,lymph nodes metastasis and pleural invasion(P<0 .05);but not correla‐ted with sex ,age ,and the smoking habit(P>0 .05) .(3) The expressions of HER‐2 and VEGF protein in the lung adenocarcinoma were positively correlated with each other(P<0 .01) .Conclusion EGFR mutation is closely related to the occurrence of lung ade‐nocarcinoma ,its high expressions in the women ,non smoking people have important clinical significance .HER‐2 and VEGF could promote the lung adenocarcinoma′s occurrence ,development and transfer .They could be used to evaluate the patients′prognosis ,and provide new molecular targeted therapy .
