not Justice.

Sceptics of judicial review-from Jeremy Waldron to those in the Judicial Power Project-have tended to attribute to their opponents an erroneous prioritisation of 'justice' over 'legitimacy'. They claim that those who make the case for judicial review do so on the grounds that 'judges know best', and that judicial review therefore helps promote the overall justness of a state's social order-rather than on the grounds that it helps enhance the overall legitimacy of a state's authority. This article interrogates that line of attack.

Association of Colonoscopy Adenoma Findings With Long-term Colorectal Cancer Incidence.

Importance: Individuals with adenomatous polyps are advised to undergo repeated colonoscopy surveillance to prevent subsequent colorectal cancer (CRC), but the relationship between adenomas at colonoscopy and long-term CRC incidence is unclear.

Objective: To compare long-term CRC incidence by colonoscopy adenoma findings.

Design, Setting, And Participants: Multicenter, prospective cohort study of participants in the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer randomized clinical trial of flexible sigmoidoscopy (FSG) beginning in 1993 with follow-up for CRC incidence to 2013 across the United States.

Colorectal cancers not detected by screening flexible sigmoidoscopy in the Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial.

Background And Objective: Diagnosis of colorectal cancer after negative findings on endoscopic evaluation raises concern about the effectiveness of endoscopic screening. We contrast screening-detected cancers with cancers not detected by screening among participants assigned to flexible sigmoidoscopy (FSG) in the Prostate, Lung, Colorectal, and Ovarian (PLCO) Cancer Screening Trial to determine the reasons for the lack of detection of prevalent lesions.

Design: Cancers detected within 1 year of a screening FSG with abnormal findings were classified as screening detected.

Utilization of surveillance colonoscopy in community practice.

Background & Aims: The recommended timing of surveillance colonoscopy for individuals with adenomatous polyps is based on adenoma histology, size, and number. The burden and cost of surveillance colonoscopy are significant. The aim of this study was to examine the use of surveillance colonoscopy on a community-wide basis.
