The authors of a new study have determined which risk factors are important predictors of advanced neoplasia in patients being screened with CT colonography. 276 of 7,620 such patients were diagnosed with advanced neoplasia. They found that age and sex were important predictors of the risk of advanced neoplasia in these patients. However, BMI and a positive family history of colorectal cancer were not. The authors suggest that these findings have implications for the appropriate selection of patients for screening.
