Serious immune‐related upper gastrointestinal toxicity of immune checkpoint inhibitors: a multicenter case series

Abstract

ICI cause severe UGI IrAEs, which are associated with enterocolitis in approximately half of the patients. Most patients with UGI IrAEs respond to corticosteroids or infliximab. These data support the recommendation to treat these patients without delay and in the same way as those with enterocolitis.
