摘 要:目的探索成人低危组急性髓系白血病(AML)完全缓解(CR)后不同巩固治疗方式对AML预后的影响。 方法回顾性分析2010年1月至2015年6月诊治的107例非难治性成人低危组AML患者病例资料,以大剂量阿糖胞苷(HD-Ara-C)为主的巩固化疗方案为对照(化疗组,38例),探索不同巩固治疗方式(微移植16例、自体移植14例及异基因移植39例)对患者预后的影响。 结果107例患者中,男59例,女48例,中位年龄33(16~59)岁,中位随访时间为36.5(5.3~79.1)个月,总复发率为20.6%(22/107),总死亡率为18.7%(20/107)。化疗、微移植、自体移植及异基因移植组5年累积复发率(CIR)分别为39.7%、6.2%、14.3%及5.6%,差异有统计学意义(P〈0.001),微移植、自体移植及异基因移植组CIR均显著低于化疗组。化疗、微移植、自体移植及异基因移植组5年疾病无进展生存(PFS)率分别为44.7%、93.8%、85.7%及78.1%,差异有统计学意义(P=0.011),其中微移植、自体移植及异基因移植组间PFS率相近,化疗组5年PFS率最低。四组5年总体生存(OS)率分别为54.9%、100%、92.9%及77.4%(P=0.076)。多因素分析显示相对于HD-Ara-C巩固化疗,异基因移植可改善PFS(HR=0.376,P=0.031),但不能改善OS(HR=0.527,P=0.179);微移植及自体移植均不能改善PFS及OS(P值均〉0.05)。 结论与HD-Ara-C巩固化疗相比,异基因移植明显降低CIR,改善PFS率,但治疗相关死亡率高。自体移植及微移植疗效与HD-Ara-C巩固化疗相当,可作为低危组AML巩固治疗的一种选择。ObjectiveTo explore the impact on prognosis in favorable-risk acute myeloid leukemia (AML) patients with different consolidation regimens after first complete remission (CR1).MethodsA total of 107 cases of non-refractory adult AML from January 2010 to June 2015 in single center were enrolled in the study. HD-Ara-C group (38 cases) as the control group, we explore the prognosis in three consolidation regimens, including micro-transplantation (16 cases) , autologous transplantation (auto-PBSCT, 14 cases) , allogeneic transplantation (allo-HSCT, 39 cases).ResultsOf 107 patients (59 males and 48 females) , with a median age of 33 (16-59) years old and a median follow-up of 36.5 (5.3-79.1) months, the overall relapse rate was 20.6% (22/107) , and overall mortality rate was 18.7% (20/107). The 5 years cumulative relapse rate (CIR) of HD-Ara-C, micro-transplantation, auto-PBSCT and allo-HSCT group were 39.7%, 6.2%, 14.3% and 5.6%, respectively (P〈0.001). The CIR of the observed group was lower than the HD-Ara-C group. The 5 years progression-free survival (PFS) rate of HD-Ara-C, micro-transplantation, auto-PBSCT and allo-HSCT group were 44.7%, 93.8%, 85.7% and 78.1%, respectively (P=0.011). The PFS of observed groups were similar, but superior to that in HD-Ara-C group. The 5-year overall survival (OS) in four groups was 54.9%, 100%, 92.9% and 77.4%, respectively (P〉0.05). Multiple factors analysis showed that compared to HD-Ara-C regimen, allo-HSCT could improve PFS (HR=0.376, P=0.031) , but not OS (P〉0.05) ; micro-transplantation and auto-PBSCT could not improve the PFS or OS (P〉0.05).ConclusionAs compared with HD-Ara-C regimen, allo-HSCT could obviously decrease CIR, improve PFS, but treatment-related mortality is high. These results show that auto-PBSCT and micro-transplantation have similar outcomes, compared to HD-Ara-C regimen, so both can be used as a option of consolidation treatment for favorable-risk AML.
