Abstract

We followed 9602 patients with Crohn's disease or ulcerative colitis for anal squamous cell carcinoma for up to 18 years. No significant increase was observed: two cases occurred vs 1.3 expected during 99 229 person-years of observation, (standardized incidence ratio = 1.6; 95 confidence interval: 0.2–5.7). Anal squamous cell carcinoma is rare even in inflammatory bowel disease. © 2000 Cancer Research Campaign
