Gut microbiota shed new light on the management of immune-related adverse events.

Immunotherapy has dramatically revolutionized the therapeutic landscape for patients with cancer. Although immune checkpoint inhibitors are now accepted as effective anticancer therapies, they introduce a novel class of toxicity, termed immune-related adverse events, which can lead to the temporary or permanent discontinuation of immunotherapy and life-threatening tumor progression. Therefore, the effective prevention and treatment of immune-related adverse events is a clinical imperative to maximize the utility of immunotherapies.
