摘 要:目的比较移植前免疫表型缓解(ICR)和血液形态学缓解对急性髓系白血病(AML)患者同胞HLA相合造血干细胞移植(MSDT)疗效的预测价值。 方法回顾性分析182例接受MSDT的AML患者(除外急性早幼粒细胞白血病),将移植前血液形态学缓解分为血细胞恢复的完全缓解(CR)、血小板未恢复的CR(CRp)、血小板和中性粒细胞均未恢复的CR(CRi),将多参数流式细胞术检测微小残留病阴性定义为ICR。 结果①全部182例AML患者中,男97例,女85例,中位年龄41(4~62)岁。②移植前CR、CRp+CRi率分别为80.8%(147/182)、19.2%(35/182);移植前CRp+CRi组、CR组的预期4年累积复发率(CIR)[(11.0±4.3)%对(16.0±7.1)%,χ2=0.274,P=0.600]、非复发死亡率(NRM)[(14.0±4.3)%对(9.0±6.3)%,χ2=0.913,P=0.339]、无白血病生存(LFS)率[(75.0±5.1)%对(75.0±8.3)%,χ2=0.256,P=0.613]、总生存(OS)率[(77.0±5.2)%对(80.0±8.1)%,χ2=0.140,P=0.708]差异均无统计学意义。③移植前ICR组(147例)与非ICR组(35例)比较,4年CIR较低[(11.3±3.4)%对(55.2±8.8)%,χ2=32.687,P〈0.001],LFS率[(76.2±4.7)%对(32.8±8.7)%,χ2=26.234,P〈0.001]和OS率[(79.0±4.7)%对(39.0±9.1)%,χ2=25.253,P〈0.001]较高,NRM差异无统计学意义[(12.5±4.1)%对(12.0±7.1)%,χ2=1.002,P=0.656]。④多因素分析显示,移植前非ICR是影响AML患者MSDT后复发[HR=11.026(95% CI 4.685~25.949),P〈0.001]、LFS[HR=5.785(95% CI 2.974~11.254),P〈 0.001]和OS[HR=5.578(95%CI 2.575~27.565),P〈0.001]的独立危险因素。 结论移植前ICR对AML患者MSDT的疗效预测价值优于HCR。ObjectiveTo assess the prognostic significance of immunophenotype complete remission (ICR) and hematological complete remission (HCR) before human-leukocyte antigen (HLA)-matched sibling donor transplantation (MSDT) in acute myeloid leukemia (AML) patients. MethodsA cohort of 182 AML (non-APL) patients undergoing MSDT in HCR was retrospectively studied [including complete remission with ANC and PLT recovery (CR), CR with incomplete PLT recovery (CRp), CR with inconplete ANC and PLT recovery (CRi)]; ICR was determined as undetective minimal resudial disease (MRD) by multi-parameter flow cytometer. Results①Of the 182 patients, 97 were male, 85 female, and the median age was 41(4-62) years. ②The CR and CRi+CRp rates were 80.8% (147/182) and 19.2%(35/182), respectively; The 4-year cumulative incidence of relapse[CIR, (11.0±4.3)% vs (16.0±7.1)%, χ2=0.274, P=0.600], non-relapse mortality[NRM, (14.0±4.3)% vs (9.0±6.3)%, χ2=0.913, P=0.339], leukemia-free survival[LFS, (75.0±5.1)% vs (75.0±8.3)%, χ2=0.256, P=0.613], and overall survial [OS, (77.0±5.2)% vs (80.0±8.1)%, χ2=0.140, P=0.708] were comparable between the CRp+CRi and CR groups. ③Compared with the non-ICR group (n=35), the ICR group (n=147) showed lower 4-year CIR [(11.3±3.4) % vs (55.2±8.8) %, χ2=32.687, P〈0.001], better 4-year LFS [(76.2±4.7)% vs (32.8±8.7)%, χ2=26.234, P〈0.001] and OS[(79.0±4.7)% vs (39.0±9.1)%, χ2=25.253, P〈0.001], and comparable NRM[(12.5±4.1)% vs (12.0±7.1)%, χ2=1.002, P=0.656]. ④Mulitvariate analysis confirmed the independent prognostic value of ICR in lower CIR [HR=11.026(95%CI 4.685-25.949), P〈0.001], higher LFS [HR=5.785 (95% CI 2.974-11.254), P〈0.001] and OS[HR=5.578 (95% CI 2.575-27.565), P〈0.001]. ConclusionThe results indicated that ICR instead of HCR pre-transplantation had a significant prognostic value in AML patients undergoing MSDT.
