Journal ArticleDOI
Screening and surveillance for the early detection of colorectal cancer and adenomatous polyps, 2008: a joint guideline from the American Cancer Society, the US Multi-Society Task Force on Colorectal Cancer, and the American College of Radiology.
Bernard Levin,David A. Lieberman,Beth McFarland,Kimberly S. Andrews,Durado Brooks,John H. Bond,Chiranjeev Dash,Francis M. Giardiello,Seth N. Glick,David W. Johnson,C. Daniel Johnson,Theodore R. Levin,Perry J. Pickhardt,Douglas K. Rex,Robert A. Smith,Alan G. Thorson,Sidney J. Winawer +16 more
TL;DR: Clinicians should be prepared to offer patients a choice between a screening test that is effective at both early cancer detection and cancer prevention through the detection and removal of polyps and those that can detect cancer early and also can detect adenomatous polyps.
Journal ArticleDOI
Colorectal cancer screening and surveillance: clinical guidelines and rationale-update based on new evidence
Sidney J. Winawer,Robert H. Fletcher,Douglas K. Rex,John H. Bond,Randall W. Burt,Joseph T. Ferrucci,Theodore G. Ganiats,Theodore R. Levin,Steven H. Woolf,David W. Johnson,Lynne M. Kirk,Scott C. Litin,Clifford Simmang +12 more
TL;DR: These guidelines differ from those published in 1997 in several ways: the screening interval for double contrast barium enema has been shortened to 5 years, and colonoscopy is the preferred test for the diagnostic investigation of patients with findings on screening and for screening patients with a family history of hereditary nonpolyposis colorectal cancer.
Journal ArticleDOI
Guidelines for Colonoscopy Surveillance After Screening and Polypectomy: A Consensus Update by the US Multi-Society Task Force on Colorectal Cancer
David A. Lieberman,Douglas K. Rex,Sidney J. Winawer,Francis M. Giardiello,David A. Johnson,Theodore R. Levin +5 more
TL;DR: New issues have emerged since the 2006 guideline, including risk of interval CRC, proximal CRC, and the role of serrated polyps in colon carcinogenesis, which suggests that adherence to prior guidelines is poor.
Journal ArticleDOI
Colonoscopic miss rates of adenomas determined by back-to-back colonoscopies.
Douglas K. Rex,Christopher S. Cutler,Gregory T. Lemmel,Emad Y. Rahmani,David W. Clark,Debra J. Helper,Glen A. Lehman,David G. Mark +7 more
TL;DR: Using current colonoscopic technology, there are significant miss rates for adenomas < 1 cm even with meticulous colonoscopy, and the results suggest the need for improvements in colonoscope technology.
Journal ArticleDOI
American College of Gastroenterology Guidelines for Colorectal Cancer Screening 2008
Douglas K. Rex,David A. Johnson,Joe Anderson,Phillip S Schoenfeld,Carol A. Burke,John M. Inadomi +5 more
TL;DR: This document is the first update of the American College of Gastroenterology (ACG) colorectal cancer screening recommendations since 2000, and it is recognized that colonoscopy is not available in every clinical setting because of economic limitations.
