[Side effects of Immune Checkpoint Inhibitors : Diagnostics and Management-an Update]

Immune checkpoint inhibitors (ICI) represent a breakthrough in cancer therapy. They are effective in various tumor entities and can be used in more and more treatment settings. This leads to an increase in the number and complexity of cases with immune-related adverse events (irAE). The most common irAE are cutaneous, gastrointestinal and endocrine side effects, whereas less common irAE include pneumonitis, nephritis, myocarditis or neurological reactions. IrAE can usually be successfully treated, mainly with corticosteroids or other immunosuppressants, but they can also result in long-term sequelae or death. The optimal management of patients with steroid-refractory or steroid-dependent side effects still remains unclear. Broad awareness of these irAE across specialties is therefore of crucial importance to ensure early diagnosis and to improve irAE management.
