Minimal residual disease (MRD) detection represents a sensitive tool to appropriately measure the response obtained with therapies for multiple myeloma (MM). The achievement of MRD negativity has superseded the conventional complete response (CR) and has been proposed as a surrogate endpoint for progression-free survival and overall survival. Several techniques are available for the detection of MRD inside (next-generation sequencing, flow cytometry) and outside (PET/CT, magnetic resonance) the bone marrow, and their complementary use allows a precise definition of the efficacy of anti-myeloma treatments. This review summarizes MRD data and results from previous clinical trials, highlights open issues related to the role of MRD in MM and discusses how MRD could be implemented in clinical practice to inform on patient prognosis and drive therapeutic decisions.
微小残留病(MRD)检测是一种灵敏的工具,可用于恰当衡量多发性骨髓瘤(MM)治疗所取得的疗效。实现MRD阴性已取代了传统的完全缓解(CR),并被提议作为无进展生存期和总生存期的替代终点。有多种技术可用于检测骨髓内(下一代测序、流式细胞术)和骨髓外(PET/CT、磁共振)的MRD,它们的互补使用能够精确界定抗骨髓瘤治疗的疗效。本综述总结了MRD数据及既往临床试验结果,突出了与MRD在MM中的作用相关的未决问题,并讨论了如何在临床实践中应用MRD来了解患者预后并指导治疗决策。
