摘要

同种异体干细胞移植治疗高风险再生障碍性贫血(AA)的效果较差,使用传统的环磷酰胺(CY)为基础的条件。使用氟达拉滨(流感)为基础的方案已导致改善预后的高危患者。在这类患者中比较这两种调理方案的数据有限。我们回顾性分析了2001年7月至2018年12月接受匹配相关供体移植的192例高危患者。中位年龄为19.5(2-52)岁。患者分为两组,Cy200抗胸腺细胞球蛋白(ATG)20 (Gp1 n = 79)或Flu120-150 Cy120-160 ATG20 (Gp2 n = 113)。Gp1患者发生移植物衰竭的风险明显较高,且多发生在危险因素>2的患者中(p = 0.02)。两组间II-IV级急性移植物抗宿主病(GVHD)和慢性移植物抗宿主病(GVHD)的发生率无显著差异。研究队列的总生存率(OS)为81.3%,无病生存率(DFS)为76.6%,无gvhd无复发生存率(GRFS)为64.1%。Gp2的DFS和GRFS明显高于Gp1: DFS分别为84.1%对68.4% (p = 0.02), GRFS为77.9%对54.4% (p = 0.01)。我们得出结论,在高风险AA中,与传统的基于流感的治疗方案相比,基于流感的治疗与更高的OS、DFS和GRFS相关。

Comparison of Conventional Cyclophosphamide <i>versus</i> Fludarabine-Based Conditioning in High-Risk Aplastic Anemia Patients Undergoing Matched-Related Donor Transplantation.

Comparison of Conventional Cyclophosphamide versus Fludarabine-Based Conditioning in High-Risk Aplastic Anemia Patients Undergoing Matched-Related Donor Transplantation.

Allogeneic stem cell transplant for high-risk aplastic anemia (AA) yields inferior results using conventional cyclophosphamide (CY)-based conditioning. The use of fludarabine (Flu)-based regimens has resulted in improved outcomes in high-risk patients. Limited data are available comparing these two conditioning regimens in such patients. We retrospectively analyzed 192 high-risk patients undergoing matched-related donor transplantation from July 2001 to December 2018. The median age was 19.5 (2-52) years. Patients were divided into 2 groups, Cy200 anti-thymocyte globulin (ATG)20 (Gp1 n = 79) or Flu120-150 Cy120-160 ATG20 (Gp2 n = 113). The risk of graft failure was significantly higher in Gp1, and the majority occurred in patients with >2 risk factors (p = 0.02). The incidence of grade II-IV acute graft versus host disease (GVHD) and chronic GVHD was not significantly different between the two groups. The overall survival (OS) of the study cohort was 81.3 %, disease-free survival (DFS) 76.6 % and GVHD-free relapse-free survival (GRFS) was 64.1%. DFS and GRFS were significantly higher in Gp2 as compared to Gp1: DFS 84.1% versus 68.4 % (p = 0.02), GRFS 77.9% versus 54.4% (p = 0.01), respectively. We conclude that Flu-based conditioning is associated with superior OS, DFS and GRFS as compared to the conventional Cy-based regimen in high-risk AA.
