Expression of cyclooxygenase-2 in colorectal cancer and its clinical significance / 中国免疫学杂志

ABSTRACT

Objective:To investigate the expression of cyclooxygenase-2(COX-2) in colorectal carcinoma tissues,and understand its clinical significance.Methods:The immunohistochemistry was used to determine the expression of COX-2 in the 43 tissues of colorectal cancer and 14 tissues of normal mocusa.Results:Positive expression of COX-2 was detected in 83.72% of colorectal cancerous tissues and in 14.29% of normal tissues and there was significant difference in expression of COX-2 between cancer tissues and normal tissues(P0.05).Conclusion:COX-2 was overexpressed in colorectal carcinoma.COX-2 maybe play an important role in carcinogenesis and progression of colorectal carcinoma.
