Abstract: |
Chimeric antigen receptor (CAR) T-cell therapy has transformed the treatment armamentarium of relapsed/refractory hematologic malignancies, enabling high response rates, and potential cure. Despite these impressive antitumor effects, many patients experience relapse or fail to respond after receiving CAR T cells. There are also several unique side effects associated with morbidity and mortality, including immune-mediated phenomena, prolonged cytopenias, B-cell aplasia, and hypogammaglobulinemia. Several studies have explored predictive biomarkers to identify patients at risk of treatment failure or adverse events. A biomarker-based approach to CAR T-cell treatment may improve patient selection by identifying risk factors for nonresponders and for severe toxicities, as well as help researchers identify targets for novel CAR T-cell products. © 2022 Elsevier Inc.
