[Immuno-Oncology Meets Intensive Care Medicine: CAR-T cells]

CAR-T cells, genetically modified tumor-targeted t-cells, revolutionized the treatment of refractory B-cell malignancies. CAR-T cell treatment however, is invariably associated with severe immune-mediated toxicities, namely Cytokine Release Syndrome (CRS) and neurological toxicity (CRES/ICANS). Although knowledge on the pathomechanism of these toxicities is still very limited, recent findings including mouse models might allow prediction, earlier recognition and targeted treatment of patients suffering from these potentially life-threatening side effects. This article summarizes current knowledge and recent findings on the management of severe CAR-T associated toxicities and gaps of knowledge stressing the importance of an interdisciplinary approach including hematology-oncology and Intensive Care Medicine.
