We agree with Drs. Rex and Winawer that a single study is unlikely to be definitive, especially when, as they suggest, variability in clinician judgment influences the identified predictors of higher risk for advanced adenoma.
We did not, however, recommend shortening the interval of surveillance colonoscopy for the low-risk category. In our study, the advanced adenoma recurrence rate at 4 years was 9% among the high-risk category and 5% among the low-risk category. The c-statistics from multivariate models incorporating demographic and lifestyle factors with adenoma characteristics indicated little discrimination between the 2 risk groups. Although these finding may be interpreted to mean that we should screen both groups at 3 years, they could just as well suggest extending the surveillance interval for both groups to 5 years.
