Expression and clinical relativity of vascular endothelial growth factor in human lung cancer / 肿瘤研究与临床

ABSTRACT

Objective To investigate the expression difference of vascular endothelial growth factor (VEGF)between lung cancer and lung benign disease,and its relation to clinical characteristics and prognosis of non-small cell lung cancer(NSCLC),and to research the possible role of VEGF in the growth of lung can- cer.Methods The expression of VEGF and microvascular density(MVD)were detected in 60 lung cancer tissues and 30 lung benign disease tissues after operation by immunohistochemical method and put up statisti- cal analysis.Results The positive rate of VEGF expression(63%)and MVD(45.13?10.27)in lung cancer tissues were both higher than those in lung benign disease tissues(27%,33?6.49)(P
