Abstract

Chimeric antigen receptor T cells are a new and exciting immunotherapeutic approach to managing cancer, with impressive efficacy but potentially life-threatening inflammatory toxicities such as cytokine release syndrome (CRS) and immune effector cell-associated neurotoxicity syndrome (ICANS). Patients with severe CRS may develop capillary leak syndrome and disseminated intravascular coagulation, with a cytokine signature similar to that of macrophage activation syndrome/hemophagocytic lymphohistiocytosis. Moderate-to-severe CRS is managed with the IL-6 receptor antagonist tocilizumab with or without corticosteroids, with questions remaining regarding the optimal management of nonresponders. ICANS is an inflammatory neurotoxicity typically occurring after CRS and characterized by impaired blood-brain barrier integrity. Symptoms of encephalopathy range from mild confusion and aphasia to somnolence, obtundation, and in some cases seizures and cerebral edema. ICANS is currently managed with corticosteroids; however, the optimal dose and duration remain to be determined. Little information is available to guide the management of patients with steroid-refractory ICANS. Numerous cytokine-targeted therapies have been proposed to manage these inflammatory toxicities, but few clinical data are available. Management of inflammatory toxicities of chimeric antigen receptor T cells often requires multidisciplinary management and intensive care, during which allergists and immunologists may…

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
