[A review of adverse events caused by immune checkpoint inhibitors].

There has been no effective therapy in the unresectable melanoma for more than 40 years. Anti-PD-1 antibody and anti-CTLA-4 antibody have totally changed the situation. They have clearly shown the survival benefits of the patients with metastatic melanoma. However, immune checkpoint inhibitors sometimes induce various kinds of immune-related adverse events (irAEs). It is very important for the clinicians to know the reported cases of irAEs and to keep in mind the symptoms of irAEs for the early detection. This review describes the previously reported irAEs and adequate managements for irAEs induced by immune checkpoint inhibitors.
