在本期中,Paiva 及其同事分析了复发/难治性多发性骨髓瘤接受嵌合抗原受体(CAR)T 细胞治疗期间,微小残留病(MRD)和临床应答的动态变化。二者均与无进展生存期延长相关,但骨髓中达到 MRD 阴性的时间早于外周血中达到完全缓解。因此,本研究指出,未来指南需要探索不依赖单克隆(M)蛋白的新型 MRD 阴性定义,以克服这一局限;在以早期缓解深度为终点的临床试验中尤为重要。相关研究见 Paiva 等人,第 365 页(1)。
In this issue, Paiva and colleagues characterize the dynamics of minimal residual disease (MRD) and clinical responses during chimeric antigen receptor (CAR) T-cell therapy of relapsed/refractory multiple myeloma.
Although both correlate with prolonged progression-free survival, MRD is reached faster in the bone marrow than complete response in peripheral blood; consequently, the study addresses the need for future guidelines to explore new MRD-negative definitions that are independent of the monoclonal (M) protein to overcome this limitation, particularly in clinical trials using early depth of response as an endpoint.
