The significance of cyclooxygenase-2 expression in human hepatocellular carcinoma.
Hepatocellular carcinoma (HCC) is one of the five most common malignancies in the world and is the second leading cause of death in Hong Kong. Previous studies have shown increased levels of cyclooxygenase-2 (COX-2) in a variety of human malignancies including HCC, suggesting that abnormal COX-2 expression plays an important role in carcinogenesis. In addition, some evidence suggests that selective COX-2 inhibitors suppress the formation of tumors in experimental models. However, there are no data in the literature on using COX-2 as an inhibitor target in HCC. The main objective of this article was to give a brief summary of the recent findings of the role of COX-2 in HCC. We briefly reviewed the significance of COX-2 in varies cancers, and then focused on the recent findings of the significance of COX-2 in HCC. Finally, we further evaluated the possibility of using COX-2 as a therapeutic target in HCC.
