Colorectal cancer is the third most common cancer in men and women. The incidence and mortality rate of the disease have been declining over the past two decades because of early detection and treatment. Screening in persons at average risk should begin at 50 years of age; the U.S. Preventive Services Task Force recommends against routine screening after 75 years of age. Options for screening i...
tal cancer screening be considered in elderly persons without previous screening? A cost-effectiveness analysis. Life expectancy and comorbidities are import factors in plan of a cancer screening. Colorectal cancer screening was shown to decrease the mortality of colorectal cancer (1,2). The U.S. Preventive Services Task Force recommends colorectal cancer screening beginning at age 50 years and...
Open Access Colonoscopy is the most effective and popular method for the screening, prevention, and diagnosis of colorectal cancer worldwide. However, there have been concerns on the ability of colonoscopy to detect adenoma. Colonoscopic examination is limited in this regard even if lesions are not missed because of variables such as the endoscopist' s skill, experience, and the degree of bowel...
BACKGROUND & AIMS The sensitivity of computed tomographic (CT) virtual colonoscopy (CT colonography) for detecting polyps varies widely in recently reported large clinical trials. Our objective was to determine whether a computer program is as sensitive as optical colonoscopy for the detection of adenomatous colonic polyps on CT virtual colonoscopy. METHODS The data set was a cohort of 1186 s...
Background and AimsColonoscopy surveillance after adenoma removal is an increasing burden in many countries. Surveillance recommendations consider characteristics of removed adenomas, but not colonoscopist performance. We investigated the impact performance on colorectal cancer risk removal.MethodsWe compared high-risk low-risk negative colonoscopy for all colonoscopies performed by colonoscopi...
Colorectal cancer is the third most cancer in the US and the second most cause of cancer deaths. The general lifetime risk of developing cancer in the United States is about 6%. Colorectal cancer almost always develops from precancerous polyps (abnormal growths) in the colon or rectum. There are various screening tests available for the colon cancer. High sensitivity FOBT, flexible sigmoidoscop...
BACKGROUND Colorectal cancer screening is widely recommended, but often under-utilized. In addition, significant demographic differences in screening utilization exist. Insurance coverage may be one factor influencing utilization of colorectal cancer screening tests. METHODS We conducted a retrospective analysis of claims for outpatient services for Washington state Medicare beneficiaries in ...
BACKGROUND Colonoscopy and sigmoidoscopy provide protection against colorectal cancer, but the magnitude and duration of protection, particularly against cancer of the proximal colon, remain uncertain. METHODS We examined the association of the use of lower endoscopy (updated biennially from 1988 through 2008) with colorectal-cancer incidence (through June 2010) and colorectal-cancer mortalit...
