Patients who have undergone adenoma with high-grade dysplasia (HGD) removal face higher risks of advanced neoplasia (AN) and colorectal cancer (CRC), with AN and CRC incidences of 44.3 and 4.4 per 1000 person-years, respectively. Those with synchronous polyps or elevated baseline carcinoembryonic antigen levels are at higher risk and may need more frequent surveillance, although regular colonoscopy visits can reduce these risks significantly.
