[Acute kidney injury in cancer patients receiving immune checkpoint inhibitor therapy-shared guidelines of FITC/SFNDT].

Abstract

Cancer treatments have been dramatically modified by the introduction and the development of immunological checkpoint inhibitors (ICI). These treatments have many side effects, including acute kidney injury (AKI). Their combination with other treatments makes the diagnosis complex. To provide guidance to physicians treating these patients, the FITC and the SFNDT have developed a set of management guidelines covering pre-treatment assessment, diagnosis of the different types of damage observed, and management of acute interstitial nephritis secondary to ICI. Collaboration between oncologists and nephrologists is mandatory. The development of onconephrology is helping to improve knowledge and identify treatment pathways. The key elements of the diagnostic process are presented. The role of renal biopsy is discussed, as it appears to be underused in relation to the expected benefits. Renal biopsy allows ICI to be continued if AKI is not related to AKI. Treatment based on glucocorticoid therapy is recommended, with regimens depending on the severity of the disease and the renal response to glucocorticoid therapy. Alternative treatments for patients resistant to corticosteroids are discussed, but strong data are lacking. Rechallenge should be discussed since it seems to be associated with a good renal prognosis.
