摘要

QuestionnnIn men 55 to 74 years of age, does annual screening with prostate-specific antigen (PSA) testing and digital rectal examination reduce mortality from prostate cancer? nnMethodsnnDesign: Randomized controlled trial (Prostate, Lung, Colorectal, and Ovarian [PLCO] Cancer Screening Trial). ClinicalTrials.gov NCT00002540.nnAllocation: {Concealed}†.*nnBlinding: Blinded (outcome adjudication committee).*nnFollow-up period: Median 12 years.nnSetting: 10 centers in the USA.nnParticipants: 76 693 men 55 to 74 years of age. Exclusion criteria included history of PLCO cancer, current cancer treatment, and > 1 PSA test in 3 years.nnIntervention: Annual screening with PSA testing for 6 years and digital rectal examination for 4 years (n = 38 343) or usual care that might include screening (n = 38 350). A serum PSA level > 4.0 ng/mL was considered to be a positive result. Men and their primary physicians were informed of test results; they decided on further diagnostic evaluation and treatment, according to standard practice.nnOutcomes: Incidence of and mortality from prostate cancer at 7 years. {The trial had > 90% power to detect a 20% relative reduction in prostate cancer mortality.}†nnParticipant follow-up: 98% at 7 years (intention-to-screen analysis).
