After autologous hematopoietic cell transplantation (HCT) in the first complete remission (CR1), patients with acute myeloid leukemia (AML) may relapse and undergo allogeneic HCT in the second complete remission (CR2). The aim of this study was to analyze the outcome of allogeneic HCT performed in CR2 comparing patients with prior consolidation by autologous HCT versus patients with chemotherapy consolidation. Included were 2619 adults with allogeneic HCT in CR2 from 2000 to 2017 with (n = 417) or without (n = 2202) prior autologous HCT. Patient groups were not entirely comparable; patients with prior autologous HCT were younger, had less often a favorable cytogenetic profile, had more commonly donors other than matched siblings, and more often received reduced-intensity conditioning. In multivariate analysis, nonrelapse mortality risks in patients with prior autologous HCT were 1.34 (1.07 to 1.67; P = .01) after adjustment for age, cytogenetic risk, transplant year, donor, conditioning intensity, sex matching, interval diagnosis-relapse, and relapse-allogeneic HCT as compared with chemotherapy consolidation. Similarly, risks of events in leukemia-free survival and graft-versus-host disease, relapse-free survival were higher with prior autologous HCT, 1.17 (1.01 to 1.35), P = .03 and 1.18 (1.03 to 1.35), P = .02, respectively. Risk of death was also higher, 1.13 (0.97 to 1.32), P = .1, but this was not significant. Postremission consolidation with autologous HCT for AML in CR1 increases toxicity of subsequent allogeneic HCT in CR2.

自体造血细胞移植(HCT)对首次完全缓解(CR)的急性髓样白血病的缓解后合并以及对第二次CR的后续异基因HCT的负面影响:欧洲血液和骨髓移植学会急性白血病工作组的研究( EBMT)。

在第一次完全缓解(CR1)中进行自体造血细胞移植(HCT)后,急性髓细胞性白血病(AML)的患者可能会复发并在第二次完全缓解(CR2)中接受同种异体HCT。这项研究的目的是分析在CR2中进行的同种异体HCT的结果,以比较自体HCT先前合并的患者与化疗合并的患者。从2000年至2017年,包括(n = 417)或没有(n = 2202)先前自体HCT的2619名CR2异基因HCT成人。患者组不是完全可比的。先前自体HCT的患者年龄较小,具有良好的细胞遗传学特征,除配对的兄弟姐妹以外,更常见的是供体,并且接受强度降低的条件更多。在多元分析中,经过年龄,细胞遗传学风险,移植年限,供体,条件强度,性别匹配,间隔诊断-复发和异基因复发性HCT调整后,先前自体HCT患者的非复发性死亡风险为1.34(1.07至1.67; P = .01)与化疗巩固相比。同样,先前的自体HCT发生无白血病生存和移植物抗宿主病,无复发生存的事件风险较高,分别为1.17(1.01至1.35),P = .03和1.18(1.03至1.35),P =分别为.02。死亡风险也更高,为1.13(0.97至1.32),P = 0.1,但这并不显着。缓解后合并自体HCT治疗CR1中的AML,会增加随后的CR2中同种异体HCT的毒性。供体,条件强度,性别匹配,间歇性诊断-复发和复发-同种异体HCT与化疗巩固相比。同样,先前的自体HCT发生无白血病生存和移植物抗宿主病,无复发生存的事件风险较高,分别为1.17(1.01至1.35),P = .03和1.18(1.03至1.35),P =分别为.02。死亡风险也更高,为1.13(0.97至1.32),P = 0.1,但这并不显着。缓解后合并自体HCT治疗CR1中的AML,会增加随后的CR2中同种异体HCT的毒性。供体,条件强度,性别匹配,间歇性诊断-复发和复发-同种异体HCT与化疗巩固相比。同样,先前的自体HCT发生无白血病生存和移植物抗宿主病,无复发生存的事件风险较高,分别为1.17(1.01至1.35),P = .03和1.18(1.03至1.35),P =分别为.02。死亡风险也更高,为1.13(0.97至1.32),P = 0.1,但这并不显着。缓解后合并自体HCT治疗CR1中的AML,会增加随后的CR2中同种异体HCT的毒性。先前的自体HCT的无复发生存率更高,分别为1.17(1.01至1.35),P = .03和1.18(1.03至1.35),P = .02。死亡风险也更高,为1.13(0.97至1.32),P = 0.1,但这并不显着。缓解后合并自体HCT治疗CR1中的AML,会增加随后的CR2中同种异体HCT的毒性。先前的自体HCT的无复发生存率更高,分别为1.17(1.01至1.35),P = .03和1.18(1.03至1.35),P = .02。死亡风险也更高,为1.13(0.97至1.32),P = 0.1,但这并不显着。缓解后合并自体HCT治疗CR1中的AML,会增加随后的CR2中同种异体HCT的毒性。
