Although evidence suggests that aspirin and celecoxib may reduce the risk of colorectal cancer (CRC), these drugs can also cause harmful side effects. The aim of this study was to characterize patient preferences for celecoxib and aspirin. Participants completed a computer-based patient decision-making questionnaire that included an educational component outlining the benefits and harms of celecoxib and aspirin. Under the base conditions 7.4% would take celecoxib and 43.6% would take aspirin; males were more willing than females to take aspirin. Patients identified the increased risk of myocardial infarction and gastrointestinal events as the primary reasons for their unwillingness to take celecoxib and aspirin, respectively. A majority of subjects would not take either drug, after considering their benefits and harms, although participants were almost six times more likely to take aspirin than celecoxib. These data serve to inform physicians and researchers regarding the variability and factors that affect patient preferences for CRC chemoprevention.
