[CAR-T therapy for malignant lymphoma]

B-cell non-Hodgkin's lymphoma is a very heterogonous malignancy with diffuse large B-cell lymphoma (DLBCL) and follicular lymphoma (FL) as the most common subtypes. Recent advances in chimeric antigen receptor T-cell (CAR-T) therapy are changing the current landscape for management of relapsed or refractory (R/R) DLBCL and R/R FL, which have a poor prognosis. Pivotal trials leading to the FDA approval of three CD19 CAR-T cells (Yescarta^®, Kymriah^® and Breyanzi^®) showed complete response (CR) rates of 40-60%, with a significant subset of patients achieving long-term disease remission. Real-world studies have also confirmed this data. Notable toxicities include cytokine release syndrome and neurologic toxicities, which are usually treatable and reversible, as well as cytopenias and hypogammaglobulinemia. Salvage chemoimmunotherapy followed by high-dose chemotherapy and autologous stem cell rescue is the standard of care for chemo-sensitive and transplant-eligible R/R DLBCL. This review highlights the approved CAR-T constructs, including their efficacy, adverse effects, and real-world data.
