Immune checkpoint inhibitors induced liver injury: an observational study
Archive ouverte
International audience. Background and aims: Immune checkpoint inhibitors (ICI), targeting programmed cell death 1 (PD-1), its ligand (PD-L1) and anticytotoxic T lymphocyte-associated protein 4 (CTLA-4) changed the landscape of cancer therapy. Liver toxicity is occurring up to 16% in patients treated with ICI. International guidelines recommend pausing immunotherapy and administering corticotherapy, regardless of the hepatitis phenotype. The aim of our study is to describe the different phenotypes of ICI induced hepatitis and to assess their evolution.
