摘要
To investigate the risk factors of tumor lysis syndrome (TLS) in relapsed/refractory multiple myeloma (MM) patients undergoing B-cell maturation antigen (BCMA) chimeric antigen receptor (CAR) T cell therapy.The clinical data of 99 relapsed/refractory MM patients receiving BCMA CAR-T cell therapy in the First Affiliated Hospital, Zhejiang University School of Medicine from July 2018 to December 2021 were collected in this study. Univariate analysis and multivariate logistic regression were performed to evaluate the risk factors of TLS following BCMA CAR-T cell therapy.Among the 99 patients, TLS occurred in 17 cases (17.2%) with an onset time of (8.9±3.0) d after BCMA CAR-T cell therapy. All TLS patients developed TLS-related clinical manifestations, including 17 cases with renal dysfunction, 8 cases with arrhythmia. All TLS patients developed cytokine release syndrome (CRS) with an onset of 1.0 (1.0, 6.5) d after CAR-T cell therapy, and 13 cases developed grade 3-4 CRS. The levels of serum uric acid, serum creatinine and the ratio of cases with grade 3-4 CRS were significantly higher in TLS patients than in non-TLS patients (all P<0.05). Multivariate logistic regression revealed that serum creatinine ( OR=1.015, P<0.01) and severe CRS ( OR=9.371, P<0.01) were independent risk factors of TLS.Relapsed/refractory MM patients undergoing BCMA CAR-T therapy shows high incidence of TLS, which are related to elevated levels of serum creatinine and severe CRS. TLS can be prevented clinically by reducing serum creatinine and controlling CRS severity.
