研究概要

在 CD19 靶向治疗后,需要采用不同的策略来检测 MRD,而不依赖 CD19 进行 B 细胞群设门。然而,必须根据可用资源使用经过验证的方案,以确保为临床决策提供可靠的结果。

研究思路结论见上方概要

在抗CD19靶向治疗后,B细胞前体急性淋巴细胞白血病(BCP-ALL)的可测量残留病(MRD)需要特定策略来识别残留原始细胞,因为CD19表达缺失或降低使其作为B细胞设门的原始标志物不一致。

由于BCP-ALL患者越来越多地能够获得CD3/CD19双特异性T细胞衔接器(BiTe)和靶向CD19的CAR-T 细胞治疗,流式细胞术实验室必须做好准备以评估治疗反应。

在此描述了在抗CD19治疗背景下经过验证的MRD检测策略,可根据不同流式细胞术实验室的设施条件加以采用。本文包括一种基于替代设门、无需使用额外标志物的8色流式细胞术(FC)策略用于BCP-ALL MRD检测(Euroflow方案),以及使用CD19替代标志物的其他策略,包括2种使用8色的方案、1种使用10色的方案和另1种使用14色/15标志物的方案。

Due to the increased access of BCP-ALL patients to therapies with CD3/CD19 bispecific T-cell engagers (BiTe) and CD19-targeted chimeric antigen receptor T-Cell (CAR-T), it is essential that flow cytometry laboratories are prepared to evaluate therapeutic responses. MATERIAL AND METHODS: Here, validated strategies for MRD detection in the context of anti-CD19 therapies are described, accessible to flow cytometry laboratories according to their different facilities. The paper includes an 8-color flow cytometry (FC) strategy for BCP-ALL MRD based on alternative gating without the use of additional markers (Euroflow protocol), as well as other strategies using alternative markers to CD19, comprising 2 protocols using 8 colors, one using 10 colors and another 14 colors/15 markers.

Different strategies are needed to detect MRD without using CD19 for B-cell population gating after CD19-targeted therapies. However, it is essential that validated protocols are used according to the available resources to ensure reliable results for clinical decision-making.
