Pituitary Complications of Checkpoint Inhibitor Use.

Abstract

Immune checkpoint inhibitors (ICIs) have revolutionized cancer therapy but are associated with a risk of endocrine immune-related adverse events (irAEs), including pituitary complications. Autoimmune hypophysitis, traditionally a rare diagnosis, has become a more frequently encountered clinical entity with the emergence of antitumor immunotherapy. This mini-review aims to consolidate current knowledge, encompassing the epidemiology, pathophysiology, clinical presentation, diagnosis, and management of pituitary complications of ICI use.
