摘 要:目的观察急性髓系白血病(AML)患者首次完全缓解期(CR1)后接受自体造血干细胞移植(auto-HSCT)或异基因造血干细胞移植(allo-HsCT)的疗效,并分析二者间的疗效差异。方法纳入2007年1月至2010年12月接受外周血造血干细胞移植治疗的139例CR1期AML患者,其中接受auto-HSCT者28例(自体组)和接受allo-HSCT者111例(异基因组)。自体组28例受者中,AML疾病分层为低危者4例,中危者19例,高危者5例;异基因组受者中,低危者5例,中危者82例,高危者24例。结果随访时间中位数为28.1个月(1.5~85.7个月),移植后所有受者均获得造血重建。自体组和异基因组非高危受者移植后3年累积白血病复发率分别为(23.7±9.3)%和(38.4±5.9)%(P=0.168);5年无白血病复发存活率(LFS)分别为(56.5±11.1)%和(57.5±5.8)%(P=0.526);5年总体存活率分别为(67.2±15.3)%和(70.2±7.2)%(P=0.364)。自体组高危受者移植后3年累积复发率分别为(73.3±22.6)%,明显高于异基因组受者的(15.4±8.3)%(P〈0.001)。自体组和异基因组高危受者移植后5年总体存活率分别为(50.0±25.O)%和(76.3±9.4)%(P=0.117);而自体组受者5年LFS为(26.7±22.6)%,明显低于异基因组受者的(73.5±9.4)%(P=0.003)。结论非高危AML患者在CR1期接受auto-HSCT是一种有效治疗方式,具有与allo-HSCT相似的疗效,但auto-HSCT对高危AML患者的疗效有限。Objective To compare the outcomes of patients with acute myeloid leukemia (AML) who underwent autologous hematopoietic stem cell transplantation (auto-HSCT) vs. allogeneic hematopoietic stem cell transplantation (allo-HSCT) in CR1. Method From Jan. 2007 to Dec. 2010, 139 patients with AML in CR1 were retrospectively categorized into auto-HSCT group (n = 28) and allo-HSCT group (n = 111). Of the 28 patients who received auto-HSCT, risk stratification was favorable (n = 4), intermediate (n = 19) and unfavorable (n = 5). Of the 111 patients who received allo-HSCT, risk stratification was favorable (n = 5), intermediate (n = 82) and unfavorable (n = 24). Result At a medium follow-up of 28. 1 (1.5-85.7) months, 139 patients all achieved hematopoietic reconstitutiorL In auto-HSCT and allo-HSCT groups with favorable and intermediate cytogenetic abnormalities, 3-year cumulative relapse rate (RR) was (23. 7 ± 9. 3)% and (38. 4 ± 5.9) % respectively (P = 0. 168), 5-year leukemia-free survival (LFS) was (56. 5± 11.1 ) % and (57. 5 ±5. 8) % (P = 0. 526) respectively, and 5-year overall survival (OS) was (67. 2 ±15. 3) % and (70. 2 ± 7. 2)% (P = 0. 364) respectively. In patients with unfavorable cytogenetic abnormalities, auto-HSCT group had significantly higher 3-year cumulative RR [(73.3 ±22:6)%] than allo-HSCTgroup [(15.4± 8.3) %] (P〈0. 001), and 5-year OS in auto-HSCT and allo-HSCT groups was (50. 0 ±25. 0) % and (76. 3 ± 9. 4) %respectively (P = 0. 117). Auto-HSCT group had obviously lower 5- year LFS [(26. 7 ±22. 6) %] than in allo-HSCT group [(73.5 ± 9. 4) %] (P = 0. 003). Though there were no significant differences of non-relapse mortality (NRM) between auto-HSCT and allo-HSCT groups in all the AML patients in CR1 (P = 0. 141), none NRM happened in auto-HSCT group. Conclusion For AML patients with favorable and intermediate cytogenetic abnormalities in CR1, auto-H
