概括
移植后循环胺 (PTCy) 与子抗胆小细胞球蛋白 (rATG) 相比,在接受不匹配的非相关捐赠者全源干细胞移植 (alloSCT) 的患者中,显示出改善的生存率和减少的非复发性死亡率 (NRM). 在这种情况下,PTCy是GVHD预防的有希望的替代方案.
科学领域:
- 血液学 血液学 血液学
- 免疫学 免疫学 免疫学
- 在瘤学瘤学.
背景情况:
- 使用不匹配的非相关捐赠者 (MMUD) 的异构干细胞移植 (alloSCT) 具有较高的移植对宿主疾病 (GVHD) 和非复发性死亡率 (NRM) 的风险.
- 子抗胸细胞球蛋白 (rATG) 是欧洲的标准预防药物,但移植后环胺 (PTCy) 正成为替代药物.
研究的目的:
- 为了比较PTCy与rATG在GVHD预防中的疗效和安全性,在MMUD患者接受第一次外周血液alloSCT的成年患者中.
- 提供证据,以指导MMUDalloSCT中GVHD预防的临床建议.
主要方法:
- 使用考克斯比例危险回归模型对欧洲血液和骨髓移植学会 (EBMT) 数据库的数据进行多变量分析.
- 包括2123名患有血液恶性瘤的成年患者,他们在2018年1月至2021年6月期间从MMUD (9/10抗原匹配) 接受了第一次外周血液alloSCT.
- 包括NRM,总生存率 (OS),无进展生存率 (PFS) 和PTCy和rATG组之间的急性和慢性GVHD发病率在内的结果的比较.
主要成果:
- 与rATG组相比,PTCy组在两年后alloSCT显示了显著较低的NRM (18%vs24.9%;HR 0.74) 和较高的OS (65.7%vs55.7%;HR 0.77) 在两年后alloSCT.
- 在PTCy组中,无进展生存率也显著改善 (59.1%对48.8%;HR 0.78).
- 急性和慢性GVHD的发病率在PTCy和rATG组之间没有显著差异.
结论:
- 移植后的循环胺 (PTCy) 与与子抗胸细胞球蛋白 (rATG) 相比,在不匹配的非相关捐助者全源干细胞移植后显著降低非复发性死亡率和改善生存率.
- 在MMUD alloSCT中,PTCy证明了作为移植与宿主疾病预防的附加价值,这表明它是对rATG.ratG.的潜在首选替代品.
