Blood:MRD阳性的AML患者也可进行异体干细胞移植

2019-08-09 MedSci MedSci原创

经过诱导和巩固治疗,风险良好的患者(FR)接受自体干细胞移植(AuSCT),风险差的患者(PR)接受异体干细胞移植(ASCT)。中等风险患者(IR)根据巩固治疗后的MRD水平决定进行AuSCT或是ASCT。无论干细胞来源,均可用于ASCT。约有361位(361/500,72%)患者获得完全缓解(CR),其中342位完成巩固治疗:ASCT 候选者有165位(48%:122位 PR,43位 IR MR

根据遗传风险、MRD情况制定移植策略是治疗AML年轻患者的一个可行的方法

移植前MRD阳性不应成为AML年轻患者进行异体干细胞移植的禁忌症

摘要:

近日,《血液》杂志上发表了一篇文章,研究人员通过细胞遗传学/遗传学和巩固治疗后的微小残留病灶(MRD)状态,来鉴别哪些新发AML年轻患者可进行干细胞移植。

经过诱导和巩固治疗,风险良好的患者(FR)接受自体干细胞移植(AuSCT),风险差的患者(PR)接受异体干细胞移植(ASCT)。中等风险患者(IR)根据巩固治疗后的MRD水平决定进行AuSCT或是ASCT。无论干细胞来源,均可用于ASCT。约有361位(361/500,72%)患者获得完全缓解(CR),其中342位完成巩固治疗:ASCT 候选者有165位(48%:122位 PR,43位 IR MRD阳性)+23位经挽救治疗后缓解的患者,共188位;AuSCT的候选者共150位(44%:115位 FR,35位IR MRD阴性)+27位无白血病相关表型的IR患者(8%),共177位。

总体上,AuSCT和ASCT的候选者中分别有110位(62%)和130位(71%)进行了预定的干细胞移植。整个队列的两年总存活率(OS)和无病存活率(DFS)分别是56%和54%。FR亚组患者的两年OS 和DFS分别是74%和 61%,PR亚组的两年OS和DFS分别是79%和61%。

总而言之,AuSCT仍可能在FR和IR MRD阴性患者中具有治疗作用。对于IR MRD阳性患者,ASCT可延长其OS和DFS至与FR患者相近。利用所有可用来源的干细胞,71%的候选患者可进行ASCT。
