5 year colorectal cancer outcomes in a large negative CT colonography screening cohort

In this study co-authored by Dr. Jennifer Weiss, the authors examined the 5-year incidence of clinically presenting colorectal cancers following a negative CT colonography (CTC) screening. The study found that clinically presenting cancers are rare in the 5 years following a negative CTC screening, a 6mm polyp size threshold is safe, and a 5-year CTC screening interval is appropriate. The results indicate that the current strategies for CTC screening for colorectal cancer are appropriate.
