摘 要: | 异基因造血干细胞移植(allo-HSCT)为可能治愈国际预后积分系统(IPSS)中、高危骨髓增生异常综合征(MDS)患者的方法.然而,MDS患者多为中、老年人,难以耐受清髓性异基因造血干细胞移植(MAC-HSCT).减低剂量预处理异基因造血干细胞移植(RIC-HSCT)具有低毒、高效等特点,被广泛应用于MDS的治疗.目前,常用的预处理方案为氟达拉滨联合烷化剂,但各种预处理方案的疗效差异较大.RIC-HSCT对IPSS中、高危老年MDS患者有其独特优势,但不同移植类型、allo-HSCT前肿瘤负荷、IPSS危险度分层及移植前合并症对RIC-HSCT疗效的影响尚无定论.笔者拟就近年来RIC-HSCT应用于MDS治疗的研究进展进行综述.

Abstract: | Allogeneic hematopoietic stem cell transplantation(allo-HSCT) is likely to be the optimum method to cure international prognostic scoring system (IPSS) intermediate and high-risk patients with myelodysplastic syndrome(MDS).However,patients suffered with MDS are usually too old to undergo myeloablative conditioning allogeneic stem cell transplantation(MAC-HSCT).On account of its advantages of higher efficiency and lower toxicity,reduced intensity conditioning allogeneic stem cell transplantation (RIC-HSCT) is widely applied in the treatment of MDS patients.Currently,fludarabine plus alkylating regimens are widely applied,but the clinical outcomes are different from each regimen.Although RIC-HSCT has unique advantages in treating intermediate and high-risk elder MDS compared with MAC-HSCT and non-HSCT therapy,whether the outcome is influenced by factors such as tumor burden,recipient age,IPSS risk stratification,type of allo-HSCT,and comorbidity before transplantation is still unclear.In this article,we review literatures on RIC-HSCT in treatment of MDS. |
