				"abstractNote": "Question: In older adults, does screening with flexible sigmoidoscopy reduce colorectal cancer (CRC) incidence and mortality more than usual care?MethodsDesign: Randomized controlled trial (RCT) (Prostate, Lung, Colorectal, and Ovarian [PLCO] Cancer Screening Trial). ClinicalTrials.gov NCT00002540.Allocation: Concealed.*Blinding: Blinded* (cause of death adjudicators).Follow-up period: 13 years (mean 11 y).Setting: 10 screening centers in the USA.Participants: 154 900 participants 55 to 74 years of age (64% < 65 y, 50% women). Exclusion criteria included history of prostate, lung, colorectal, or ovarian cancer; ongoing treatment for cancer other than basal or squamous cell skin cancer; and after 1994, assessment using a lower endoscopic procedure in the past 3 years.Intervention: Screening with flexible sigmoidoscopy at baseline and at 3 or 5 years (n = 77 445) or usual care (n = 77 455).Outcomes: CRC mortality. Other outcomes included CRC incidence, all-cause mortality, and screening-related harms.Participant follow-up: 99.9% for vital status; compliance with annual study questionnaire was 94% (intention-to-screen analysis).Main results: In the screening group, 83% of participants had flexible sigmoidoscopy at baseline and 54% at 3 or 5 years, 29% had ≥ 1 positive result (mass or polyp detected), and 77% of those with positive results had colonoscopy within 1 year. Flexible sigmoidoscopy screening reduced risk for overall and distal CRC mortality more than usual care; groups did not differ for proximal CRC mortality or mortality from other causes, excluding prostate, lung, colorectal, or ovarian cancer (Table). Screening reduced risk for incident CRC, including distal and proximal cancer (Table). Among participants who had flexible sigmoidoscopy, 20% of men and 13% of women had false-positive results and the rate of perforation among these participants was 107.5 per 100 000 colonoscopies.Conclusion: In older adults, screening with flexible sigmoidoscopy reduced colorectal cancer incidence and mortality more than usual care.Colorectal cancer screening with flexible sigmoidoscopy vs usual care in older participants†Outcomes‡Events per 10 000 person-yAt a mean 11 y of follow-upSigmoidoscopyUsual careRRR (95% CI)NNS (CI)Colorectal cancer mortality2.93.926% (13 to 37)871 (567 to 1874)Distal colorectal cancer mortality1.02.050% (36 to 62)Not reportedProximal colorectal cancer mortality1.61.73% (−22 to 23)Not significantColorectal cancer121521% (15 to 28)282 (210 to 427)Distal colorectal cancer5.67.929% (20 to 36)Not reportedProximal colorectal cancer6.07.014% (3 to 24)Not reportedEvent rateMortality from other causes§11.8%12.0%2% (−1 to 4)Not significant†NNS = number needed to invite to screening; other abbreviations defined in Glossary.
