    Patients with inflammatory bowel disease (IBD) have an increased risk of developing colorectal cancer (CRC), particularly with long-standing IBD.

  • 2

    A case-cohort study identified 87 IBD patients with CRC and 200 without CRC, assessing the incidence of nonconventional (NC) lesions.

  • 3

    Both conventional and NC lesions were associated with an increased risk of CRC, with conventional lesions showing a stronger correlation.

  • 4

    In the post-high-definition surveillance era, conventional lesions had a higher hazard ratio for CRC compared to NC lesions.

  • 5

    Misclassifications of NC lesions in the pre-HD era may have biased risk estimates, complicating the understanding of their neoplastic potential.
