Abstract: Objective To study the correlation between vascular endothelial growth factor(VEGF) and cyclooxygenase-2 (COX-2) in clear renal cell carcinoma (CRCC).Methods In 60 cases of CRCC and 10 cases of normal renal tissue,immunohistochemistry was used to examine the expression of COX-2 and VEGF.Results The positive expression rate of COX-2 in CRCC (76.7％) was significantly higher than that in normal renal tissue (20％) (x2 =10.28,P ＜0.01).The positive expression rate of VEGF in CRCC(73.3％) was significantly higher than that in normal renal tissue (20％) (x2 =8.58,P ＜0.01).The expressions of COX-2 and VEGF in CRCC were correlated with each other (r =0.469,P ＜0.01).Conclusions The expressions of COX-2 and VEGF were involved in the pathophysiolical processes of clear renal cell carcinoma.The expression levels of COX-2 and VEGF might be used to evaluate the development of clear renal cell carcinoma.
