Severe ileitis associated with capecitabine: Two case reports and review of the literature

Abstract

Capecitabine is a commonly used anticancer drug, which has been associated with adverse events, including skin and gastrointestinal symptoms, such as vomiting and diarrhea. We herein present treated two rare cases of capecitabine‑associated ileitis. In one of the patients, ileitis occurred during combination chemotherapy for metastatic colon cancer, despite previous good tolerance to this drug; the other patient developed ileitis following adjuvant single‑agent treatment. The first case is unlike previously reported cases, in which patients had no past exposure to capecitabine. Ileitis may be severe but reversible with early diagnosis and proper supportive treatment, and patients may resume chemotherapy following capecitabine discontinuation.
