Clinical outcomes and safety of CAR-T cells in treatment of T-Cell acute lymphoblastic leukemia/lymphoma
摘要
Relapsed or refractory T-cell acute lymphoblastic leukemia/lymphoma (r/r T-ALL/LBL) are frequently aggressive and associated with unfavorable prognoses. Pan-targeted Chimeric Antigen Receptor (CAR) T-cell therapy have shown promising results in clinical trials. In recent years, CD7 CAR T-cell and CD5 CAR T-cell demonstrate effectiveness in treating r/r T-ALL/LBL patients with bone marrow infiltration. However, nearly half of r/r T-ALL/T-LBL patients are accompanied by extramedullary disease (EMD), where comprehensive data on the efficacy and safety of CAR T-cell therapy remain limited. Additionally, CD7 CAR T-cell and CD5 CAR T-cell therapy can cause severe immunodeficiency and hematologic toxicity, complicating with difficult immune reconstitution. This review provides an in-depth analysis of the safety profile and adverse events associated with CAR T-cell therapy in r/r T-ALL/LBL, with a a particular emphasis on its impact in patients with EMD.
