Abstract
We herein report a case of immune-related colitis induced by the long-term use of nivolumab. A 62-year-old Japanese man was treated with nivolumab at 3 mg/kg every 2 weeks for advanced lung adenocarcinoma. The patient was admitted to our hospital due to non-bloody watery diarrhea after the 70th dose of nivolumab. A biopsy specimen of the colon mucosa revealed evidence of colitis with cryptitis and crypt microabscesses. He was diagnosed with immune-related colitis and started on predonisolone 60 mg/day. Subsequently, his symptoms remarkably resolved. Consideration of immune-related adverse events up to several years after the initiation of nivolumab is important.
