Medical Research: What is the background for this study? What are the main findings?
Dr. Scheiman: Using aspirin or other nsaids to reduce the risk of many cancers has been an active area of investigation. This study demonstrates in an animal model that a commonly used nsaid (naproxen) reduces bladder tumor development, while the concomitant use of an acid blocking drug– which has been shown in many clinical studies to reduce the ulcers and bleeding associated with nsaids in humans – is also effective. Naproxen has been shown to reduce colon polyps and skin cancers in animal models as well, so this broad effect demonstrates a novel strategy to test in clinical trials.
Medical Research: What should clinicians and patients take away from your report?
Dr. Scheiman: The study shows that using two commonly used classes of drugs together (one which, the proton pump inhibitor, can mitigate the adverse GI side effects of the other without affecting the cancer-reducing effect) may have value to reduce the risk of a number of common cancers. This idea needs to be studied in a clinical trial.
