The advanced adenoma bridges benign and malignant states and may be the most valid neoplastic surrogate marker for present and future colorectal cancer risk. We define the advanced adenoma as an adenoma with significant villous features (>25%), size of 1.0 cm or more, high-grade dysplasia, or early invasive cancer. Prevention studies should demonstrate a high efficacy in reducing the number of advanced adenomas. We should use the advanced adenoma in the evaluation of new screening technology, nutritional interventions, and chemoprevention agents because the advanced adenoma is a more desirable target for screening efficacy than is the more uncommon but life-threatening cancer stage or the more common but early, less significant small adenoma stage.
