Colorectal Cancer Screening Modalities: Variable Uptake, Variable Yield

 

Am Fam Physician. 2016 Jun 15;93(12):1032a-1036.

Clinical Question

How acceptable are various colorectal cancer screening modalities, and what is the yield in population-based screening programs?

Bottom Line

Based on the initial round of screening in this randomized trial, it appears that more patients complete fecal immunochemical testing (FIT) than colonography or colonoscopy. Using the most conservative estimate, the yields of advanced adenomas and advanced neoplasms are similar. If considering only those participants who were actually screened (not the total number invited to participate), colonoscopy found more of these lesions but also had the lowest participation rate. (Level of Evidence = 2b)

Synopsis

These researchers assigned 16,087 patients to one of four screening approaches: three cycles of FIT every two years (n = 9,739), a single reduced-preparation computed tomographic colonography (n = 2,617), a single full-preparation computed tomographic colonography (n = 2,625), or a single colonoscopy (n = 1,106). The participants were all residents of
