Giving patients checkpoint inhibitors, which are antibodies directed against PD-1 and similar proteins, has revolutionized the treatment of cancer, especially malignant melanoma. However, this therapy may cause immune-related adverse events that usually can be controlled but also may be severe. These adverse events commonly affect the skin, gastrointestinal tract, lungs, and endocrine system (especially the thyroid, adrenal, and pituitary glands) and, less often, the musculoskeletal, renal, nervous, hematologic, ...References1.
