研究概要

我们的结果表明,无论 CD58 表达强度如何,InO 后的 MRD 阴性率均较高。

研究思路结论见上方概要

CD58缺失已被描述为blinatumomab和CAR-T 细胞治疗耐药的机制,作为T细胞活化反应的调节因子发挥作用。

我们使用流式细胞术评估了CD58平均荧光强度(MFI)对接受inotuzumab ozogamicin(InO)治疗的B细胞急性淋巴细胞白血病患者实现可测量残留病(MRD)阴性的概率的影响。

CD58 MFI每增加1000单位,实现MRD阴性的比值比为1.03。

CD58 loss has been described as a mechanism of resistance to blinatumomab and chimeric antigen receptor T-cell therapy, functioning as a modulator of response to T-cell activation.

Using flow cytometry, we evaluated the impact of CD58 mean fluorescence intensity (MFI) on the probability of achieving measurable residual disease (MRD) negativity in patients with B-cell acute lymphoblastic leukemia treated with inotuzumab ozogamicin (InO).

The odds ratio of achieving MRD negativity was 1.03 for every 1000 unit increase in CD58 MFI.

Our results suggest that MRD negativity rates after InO are high, regardless of the intensity of CD58 expression.
