Inhibition of Cyclooxygenase-2
Multiple lines of evidence suggest that cyclooxygenase-2 (COX-2), an inducible form of COX, represents a potential pharmacologic target to prevent cancer. Key data suggesting a causal relationship between increased COX-2 activity and carcinogenesis and possible mechanisms of action of COX-2 in this context will be discussed. The possibility that COX-2 represents a pharmacological target for preventing upper aerodigestive cancers (head and neck, lung) will be emphasized. Importantly, clinical trials have been initiated to assess the chemopreventive properties of selective COX-2 inhibitors.
