CONTEXT A recent expert panel recommended that persons at average risk of colorectal cancer (CRC) begin screening for CRC at age 50 years using 1 of several strategies. However, many aspects of different CRC screening strategies remain uncertain. OBJECTIVE To assess the consequences, costs, and cost-effectiveness of CRC screening in average-risk individuals. DESIGN Cost-effectiveness analys...
BACKGROUND Because the burden of colorectal cancer (CRC) seems to be increasing in First Nations, it is important to better understand CRC screening utilization. The objective of this study was to describe CRC screening among First Nations living in Manitoba. METHODS The Federal Indian Register was linked to two provincial databases. A negative binomial model was used to compare the probabili...
BACKGROUND The U.S. Preventive Services Task Force requested a decision analysis to inform their update of recommendations for colorectal cancer screening. OBJECTIVE To assess life-years gained and colonoscopy requirements for colorectal cancer screening strategies and identify a set of recommendable screening strategies. DESIGN Decision analysis using 2 colorectal cancer microsimulation mo...
BACKGROUND Screening for colorectal cancer (CRC) using guaiac based faecal occult blood tests (FOBT) has an estimated programme sensitivity of >60% but <30% for strictly asymptomatic CRC in a single screening round. In search for improved non-invasive tests for screening, we compared a test for faecal calprotectin (PhiCal) with a human haemoglobin immunochemical FOBT (FlexSure OBT). METHODS I...
BACKGROUND Lower rates of screening among minorities and low-income populations contribute to colorectal cancer health disparities. Therefore, we examined patterns of colorectal cancer screening and associations with race-ethnicity, education, and income over time. METHODS Repeated cross-sectional data from the Medicare Current Beneficiary Survey of noninstitutionalized colorectal cancer-free...
BACKGROUND Primary care physician (PCP) actions are pivotal to colorectal cancer (CRC) screening performance, and guidelines recommend discussion with patients about test options and potential benefits and harms. This article profiles patterns of discussion about and recommendations for screening and explores potential associations with multilevel factors (patient, clinician, practice, and envi...
INTRODUCTION Colorectal cancer (CRC) screening rates are low in New Mexico. We used statewide surveys of primary care physicians and the general population to characterize CRC screening practices and compare perceptions about screening barriers. METHODS In 2006, we surveyed 714 primary care physicians in New Mexico about their CRC screening practices, beliefs, and perceptions of patient, prov...
BACKGROUND Colorectal cancer (CRC) is one of the most common cancers worldwide and a good candidate for screening programmes. However, there is controversy concerning which of the available screening tests should be used. SUMMARY There is general agreement that screening for CRC in the asymptomatic population should begin at the age of 50. Several different screening methods are available whi...
CONTEXT Computed tomographic (CT) colonography has been recognized as an alternative for colorectal cancer (CRC) screening in average-risk individuals, but less information is available on its performance in individuals at increased risk of CRC. OBJECTIVE To assess the accuracy of CT colonography in detecting advanced colorectal neoplasia in asymptomatic individuals at increased risk of CRC u...
PURPOSE This study aims to investigate the current situation of national colorectal cancer screening by analyzing participation rates, positive rates of screening methods and screening rate of secondary screening tests in colorectal screening of the national cancer screening program in 2008. MATERIALS AND METHODS With database about target population and screened individuals of the national c...
