RESUMO
BACKGROUND: Colorectal cancer is a leading cause of cancer-related death. Screening for colorectal cancer is a rational and cost-effective strategy for reducing the incidence of colorectal cancer and related mortality. Despite endorsement by academic and health care organizations, patient awareness and compliance with screening is low, partly because of patient-related barriers to screening. METHODS: A convenience sample of adults attending the internal medicine and family practice clinics of a community teaching hospital was studied. A description of fecal occult blood testing (FOBT), sigmoidoscopy, and colonoscopy procedures was given in a packet along with a questionnaire. The questionnaire focused on screening procedures followed in our hospital (i.e., yearly FOBT and sigmoidoscopy every 5 years or colonoscopy every 10 years for average-risk individuals). RESULTS: Of the 193 patients who responded, 55% preferred sigmoidoscopy and FOBT, 29% chose colonoscopy, and 16% wanted no screening. Those with knowledge of someone with colon cancer or colon polyps reported a significantly higher preference for screening than those without such knowledge. Catholics were most likely to prefer no screening compared with non-Catholics. Ex-smokers (compared with all others) were more likely to want screening. Catholics were least likely to want colonoscopy. Patients with previous experience of colorectal screening preferred future screening. Those preferring no screening were significantly younger than those who expressed a preference for screening. CONCLUSION: The results of this study demonstrate diversity in patient choices for colorectal cancer screening. A focus on people's preferences rather than on the test itself may help develop and target appropriate intervention for prevention of colorectal cancer.
