Abstract

Objective To investigate the expression of COX-2 and angiogenesis in colorectal carcinoma tissue.Methods The expressions of COX-2 and MVD of 88 cases of colorectal carcinoma and 20cases of control tissue were examined by immunohistochemical staining. Results Compared with normal control,positive expression rates of COX-2(3/20 vs 64/88),and CD34(7/20 vs 74/88)of colorectal carcinoma tissue increased significantly(P＜0.05).MVD in COX-2 positive expressed tissue(63.24-20.4)was higher than that in COX-2 negative expressed tissue(41.2±29.8)(P＜0.01).Conclusion COX-2 is overexpressed in colorectal carcinoma tissue,which may have a strong relationship with MVD. Key words: Coloreetal carcinoma; COX
