Computed tomography colonography for colorectal cancer screening.

COMPUTED TOMOGRAPHIC COLONOGRAPHY (VIRTUAL COLONOSCOPY) FOR SCREENING OF COLORECTAL CANCER INTRODUCTION The California Technology Assessment Forum is requested to review the scientific evidence for the use of computed Tomographic Colonography (virtual colonoscopy) for screening of colorectal cancer

[Efficacy of CT colonography versus colonoscopy in screening for colorectal cancer].

OBJECTIVE To determine the efficacy and effectiveness of CT colonography in comparison with those of colonoscopy in screening for colorectal cancer. MATERIAL AND METHODS We systematically reviewed all the studies in the scientific literature that assessed the efficacy of CT colonography in screening for colorectal cancer. We excluded articles that assessed the efficacy of other screening tech...

The role of CT colonography in a colorectal cancer screening program.

Computed tomography colonography (CTC) has the potential to become a major component of colorectal cancer (CRC) screening programs and to have a significant effect on CRC prevention. This article describes the potential role of CTC within the framework of colorectal cancer screening. Current screening recommendations and traditional screening tests are reviewed, followed by a summary of recent ...

Cost-effectiveness of computerized tomographic colonography versus colonoscopy for colorectal cancer screening.

BACKGROUND Computerized tomographic (CT) colonography is a potential alternative to colonoscopy for colorectal cancer screening. Its main advantage, a better safety profile, may be offset by its limitations: lower sensitivity, need for colonoscopy in cases where results are positive, and expense. METHODS We performed an economic evaluation, using decision analysis, to compare CT colonography ...

Study protocol: population screening for colorectal cancer by colonoscopy or CT colonography: a randomized controlled trial

BACKGROUND Colorectal cancer (CRC) is the second most prevalent type of cancer in Europe. Early detection and removal of CRC or its precursor lesions by population screening can reduce mortality. Colonoscopy and computed tomography colonography (CT colonography) are highly accurate exams and screening options that examine the entire colon. The success of screening depends on the participation r...
