Prostaglandin inhibitors and the chemoprevention of noncolonic malignancy.

Much has been learned about the role of NSAIDs as cancer preventives through epidemiologic and experimental studies. The pathways of carcinogenesis in the gastrointestinal tract are initiated by many different genetic, environmental, infective, and lifestyle factors. It is possible that the final common pathway of all these malignancies may have some common features. It is conceivable that head and neck, esophageal, gastric, and colorectal epithelial carcinogenesis all are influenced by or require COX-2 up-regulation as a step toward transformation. Intuitively, it is possible that selective COX-2 inhibitors may have a preventive role in all these epithelial malignancies. Today's challenge is to translate this information into clinical trials to define what role, if any, COX inhibition might play in the prevention of these malignancies.
