Nonsteroidal anti-inflammatory drugs (NSAIDS) in colorectal cancer chemoprevention.
Colorectal carcinoma is an important, feasible and attractive target for chemoprevention because a) it is a major cause of mortality in the United States and in other developed countries worldwide, b) there is a high mortality associated with advanced disease, c) there is a well described molecular carcinogenesis pathway and d) recent advances in molecular genetics will improve the ability to identify high-risk subjects.
Epidemiological data, colonoscopic screening and advances in molecular genetics has made possible the identification and selection of subjects at increased risk of developing colorectal cancer.
Due to this new information it may be possible to impede malignant cellular transformation with drugs.
Such intervention with relatively simple maneuvers, such as a low daily dose of aspirin, can potentially reduce mortality from colorectal cancer.
Prospective trials need to confirm experimental and epidemiological data supporting the efficacy of aspirin and other NSAID as chemopreventive agents before they can be used in the general population at risk.
To use cancer chemopreventives effectively and safely in an asymptomatic population, the risks should be minimized and the benefits maximized by determination of optimal dose, schedule and chemopreventive mechanism of the NSAID.
By linking the putative mechanism of drug action to effect endpoints, we expect to know whether the chemopreventive intervention is likely to be effective in a given individual.
