Core Tip
Core Tip: Patients with Crohn's disease (CD) are at a high risk of developing small and large bowel cancer. Regional differences exist in the prevalence of colorectal cancer, with more reports of right- and left-sided colorectal cancer in Western and Asian countries, respectively. The disease is detected at an advanced stage, and local recurrence is common, resulting in poor prognosis. Although surveillance programs have been established for ulcerative colitis, programs for colorectal cancer, especially anal cancer in CD, are lacking. Therefore, there is an imperative to focus on CD-related anal cancer and establish appropriate surveillance programs.
