Objective To explore whether vasculogenic mimicry(VM) exists in non-small cell lung cancer(NSCLC) or not and to elucidate the relationship between VM and the expression of VEGF.Methods The expression of VEGF and VM in 160 specimens of NSCLC and 20 specimens of normal lung tissue were detected by immunohistochemical and histochemical staining.Results The positive rates of VM and VEGF protein in NSCLC were 36.9% and 51.3%,respectively,but 0% and 0% in normal lung tissue.The difference was significant(P<0.05)....
