治疗相关性白血病异基因造血干细胞移植疗效分析

目的:探讨异基因造血干细胞移植（allo-HSCT）对治疗相关性白血病（TRL）的临床效果。方法:回顾性分析2012年4月至2020年2月于航天中心医院接受allo-HSCT的14例TRL患者的临床资料,分析其疗效及生存情况。结果:14例患者中,男性5例,女性9例;中位年龄35岁（12~59岁）;急性髓系白血病12例,慢性淋巴细胞白血病/小细胞淋巴瘤1例,急性淋巴细胞白血病1例。移植时4例骨髓完全缓解,3例骨髓部分缓解,其余7例均未缓解。亲缘全相合移植5例,单倍型移植9例,均采用清髓性预处理方案。14例患者均顺利植活,中位粒细胞植活时间为16 d（10~24 d）,中位血小板植活时间为13 d（10~34 d）。7例发生Ⅰ~Ⅱ级急性移植物抗宿主病（GVHD）,6例发生慢性GVHD,2例发生Ⅲ级肠道GVHD。中位随访时间32个月（4~97个月）,14例患者中5例死亡。结论:allo-HSCT可以改善TRL患者的预后,提高长期生存率。

Efficacy analysis of allogeneic hematopoietic stem cell transplantation on therapy-related leukemia

Objective:To investigate the clinical efficacy of allogeneic hematopoietic stem cell transplantation (allo-HSCT) on therapy-related leukemia (TRL).Methods:The clinical data of 14 patients with TRL who received allo-HSCT in Aerospace Central Hospital from April 2012 to February 2020 were retrospectively analyzed, and the therapeutic efficacy and survival status were also analyzed.Results:Of the 14 patients, 5 were males and 9 were females; the median age was 35 years old (12-59 years old). There were 12 patients with acute myeloid leukemia, 1 patient with chronic lymphocytic leukemia/small cell lymphoma, and 1 patient with acute lymphoblastic leukemia. At the time of transplantation, 4 patients achieved bone marrow complete remission, 3 patients achieved bone marrow partial remission, and the remaining 7 patients had no remission. Five patients received HLA-matched sibling transplantation, 9 patients received haplotype transplantation, and they all received myeloablative pretreatment schemes. All 14 patients were successfully implanted; the median engraftment time of granulocyte was 16 d (10-24 d), and the median engraftment time of platelet was 13 d (10-34 d). Grade Ⅰ-Ⅱ acute graft-versus-host disease (GVHD) occurred in 7 patients, chronic GVHD occurred in 6 patients, and grade Ⅲ intestinal GVHD occurred in 2 patients. The median follow-up time was 32 months (4-97 months). Among 14 patients, 5 patients died.Conclusion:The allo-HSCT can improve the prognosis and long-term survival rate of TRL patients.
