Abstract Capecitabine is an oral 5-fluorouracil prodrug with antimetabolite activity commonly used in advanced colorectal and breast cancer. It presents with a generally good toxicity profile and most of the adverse events can be managed effectively. Enterocolitis is a rare, under-reported, but potentially fatal adverse event associated with capecitabine use. To the best of our knowledge, there are 21 cases of capecitabine-related enterocolitis reported in the literature. We herein present a narrative literature review of enteritis/colitis cases associated with capecitabine use, with highlight to the most common clinical presentation, common imaging and microscopic findings and management approach. We furthermore present a case of severe capecitabine-related enteritis.
