Core Tip
Core Tip: This retrospective study developed and validated a machine learning model using seven non-invasive predictors, serum thymidine kinase 1 protein, cytokeratin 19 fragment, carbohydrate antigen 19-9, age, diastolic blood pressure, fecal immunochemical test, and sex, to predict the three-year risk of incident advanced adenoma (AA) in patients with non-AA. The model achieved high discriminative performance [area under the receiver operating characteristic: (1) 0.988 in training; and (2) 0.767 in external validation] and superior clinical utility over traditional methods. An open-access web application was deployed to enable precise detection of patients at high-risk of developing AA, offering a novel tool to guide more intensive follow-up for this high-risk subgroup.
