摘要目的 探讨遗传上HLA半相合外周血造血干细胞移植(Haplo-PBSCT)对首次复发后的成人急性髓系白血病(AML)的治疗效果.方法 89例成人AML患者接受常规柔红霉素-高剂量阿糖胞苷(DA/Hi-Ara-C)化疗缓解后出现首次复发,其中复发后接受Haplo-PBSCT治疗者53例,平均年龄38.6岁(18～51岁),复发时间为首次缓解后7.7个月(1～24个月);接受去甲氧柔红霉素-中剂量阿糖胞苷(iDA/Mid-Ara-C)或米托蒽醌-中剂量阿糖胞苷(MA/Mid-Ara-C)方案继续化疗者26例,平均年龄47.6岁(18～61岁),复发时间为首次缓解后8.9个月(1～30个月).结果 接受Haplo-PBSCT治疗者和接受化疗者再次完全缓解率(CR)分别为86.7%(46/53)和38.1%(9/23),两者比较,差异有统计学意义(P＜0.01).接受Haplo-PBSCT治疗者和接受化疗者36个月的疾病进展后存活(SPP)率分别为43.4%(23/53)和11.5%(3/26),两者比较,差异有统计学意义(P＜0.05).结论 相对于接受iDA/Mid-Ara-C或MA/Mid-Ara-C方案继续化疗者,Haplo-PBSCT能明显提高首次复发后AML患者的再次缓解率以及延长SPP时间.

abstractsObjective To investigate the therapeutic effects of haploidentical hematopoietic stem-cell transplantation (Haplo-PBSCT) for acute myeloid leukemia in first relapse after complete remission by standard induction chemotherapy. Methods Eighty-nine cases of AML in first relapse after complete remission by standard DA/Hi-Ara-C regimens induction chemotherapy were evaluated retrospectively. Fiftythree cases were grafted by haplo-PBSCT and 26 cases were treated with iDA/Mid-Ara-C or MA/ Mid- Ara-C agents. Results The second remission rate in haplo-PBSCT group and continuous chemotherapy group was 86. 7 % (46/53 cases) and 38. 1% (9/23 cases) respectively (P＜0. 01). Survival postprogression (SPP) at 36th month was 43. 4 % (23/53 cases) in haplo-PBSCT group and 11.5 % (3/26 cases) in continuous chemotherapy group (P ＜ 0. 05). Conclusion Haplo-PBSCT could significantly increase the second remission rate and prolong the survival time of patients with acute myeloid leukernia in first relapse after complete remission by standard induction chemotherapy.
