Objective To study the expression and the relation of vascular endothelial growth factor (VEGF)and matrix metal proteinase-2(MMP-2)in rectal cancer and evaluate their roles in rectal carcinogen- esis and development.Methods The expression of VEGF and MMP-2 in 52 cases of rectal cancer was de- tected by immunohistochemical SP technique.12 cases normal rectal tissue served as the control group.Re- suits The expression of VEGF in rectal carcinoma(67.3 %)was much higher than that in control group(P
