CT Colonography Versus Optical Colonoscopy: Cost-Effectiveness in Colorectal Cancer Screening

Purpose: CT colonography (CTC) has been accepted as an optical colonoscopy (OC) alternative for colorectal cancer (CRC) screening by some guidelines, while others maintain that the data is insufficient. CTC’s less invasive nature may improve compliance; however, cost and need colonoscopy, if lesions are detected, remain obstacle implementation. As a result, authors set out to determine cost-effectiveness of CTC in context its drawbacks advantages when compared with OC within Canadian context. Methods: Using decision analysis software, economic was performed comparing CRC asymptomatic patients. The 10-year primary outcome measure study cost, difference 100,000 patients, one quality adjusted life year gained. sensitivities, specificities, polyp prevalence rates were derived from literature. each test local data. Results: Local 764.36 CAD 580.01 CTC. In case normal OC, reassessment would not be necessary 10 years, whereas average-risk population must repeated every 5 years. incremental ratio, or additional per calculated 3,390.76 CAD.
