Screening Strategies for Colorectal Cancer (1994)
- There is insufficient evidence to support the inclusion or exclusion of fecal occult blood testing or sigmoidoscopic or colonoscopic screening of asymptomatic patients over 40 years of age.
- There is fair evidence to support screening with colonoscopy of patients in kindreds with the cancer family syndrome and patients with ulcerative colitis.
- Randomized controlled trials are needed to determine the benefit of screening with sigmoidoscopy. Development of better risk stratification for screening if a high research priority.
