概括
弗卢达拉-环胺-三硫调节剂对于患有高风险骨髓发育性综合征或急性骨髓性白血病的老年患者,接受顺序性干细胞移植,是安全的. 这种疗法显得有前途,特别是在晚期疾病中,其生存结果与基于梅尔法兰的调节结果相比较.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 移植免疫学 移植免疫学
背景情况:
- 全基性造血干细胞移植 (allo-HSCT) 面临复发和毒性等挑战,特别是在高风险的老年骨髓质疏松症候群 (MDS) 或急性骨髓性白血病 (AML) 患者中.
- 基于三硫的调节已在HLA匹配的allo-HSCT中显示出可行性,但其在HLA-haploidentical移植 (HaploT) 中的使用理解较少.
- 有限的数据存在于Treosulfan在HaploT设置中对高风险MDS/AML的老年患者的疗效和安全.
研究的目的:
- 为了比较fludarabine-cyclophosphamide-melphalan (FC-Mel) 与HaploT之前的fludarabine-cyclophosphamide-treosulfan (FC-Treo) 调节方案的疗效和安全性.
- 评估包括整体存活率 (OS),无白血病存活率 (LFS),复发率和高风险MDS/AML的老年患者的非复发死亡率 (NRM) 的结果.
- 评估这些调节方案对移植,移植与宿主疾病 (GvHD) 和外骨毒性的影响.
主要方法:
- 对80名患有高风险MDS/AML的患者 (≥50岁) 的回顾性分析,这些患者在2009-2021年期间接受了HaploT.
- 患者接受了FC-Mel (110 mg/m2) 或FC-Treo (30 g/m2) 调节,随后接受了移植后的环胺 (PTCy).
- 为了平衡患者特征,进行了匹配对分析,结果有21对匹配对进行比较.
主要成果:
- 两年的OS (66%) 和LFS (66%) 在FC-Mel和FC-Treo组之间相似 (分别为p=0.8和p=0.57).
- 与FC-Treo相比,FC-Mel的复发率显著较低 (0%与24%,p=0.006),但NRM较高 (33%与10%,p=0.05).
- 在两种调节方案之间,植入动力学和急性/慢性GvHD发生率是可比的.
结论:
- 与FC-Treo和PTCy配合的HaploT是老年患者 (≥50岁) 患有高风险MDS/AML的安全有效选择,特别是在晚期的疾病中.
- FC-Treo 显示出有利的外骨髓毒性特征,这表明可能需要剂量强化以改善抗白血病活性.
- 虽然FC-Mel的复发率较低,但FC-Treo提供了一个可行的替代方案,具有可比的生存率和潜在的NRM降低.

Bone marrow transplant is a potential cure for several diseases, including cancer and specific genetic disorders. Notably, this procedure is applicable for patients suffering from aplastic anemia, certain types of leukemia, severe combined immunodeficiency disease (SCID), Hodgkin's disease, non-Hodgkin's lymphoma, multiple myeloma, thalassemia, sickle-cell disease, and certain cancers.

Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.
