概括
早期预防性供体淋巴细胞输液 (DLI) 显著改善了无白血病的生存率,并减少了急性白血病的全源干细胞移植后复发率,而不是预防性DLI.
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:
- 供体淋巴细胞输液 (DLI) 是预防复发后异构造血源干细胞移植 (allo-HSCT) 的标准方法.
- 将早期预防性DLI (Pro-DLI) 与由可测量的残留疾病 (MRD) 引发的预防性DLI (Pre-DLI) 进行比较,对于优化急性白血病的结果至关重要.
研究的目的:
- 为了比较预防性DLI与预防性DLI在预防急性白血病的allo-HSCT后复发的疗效.
- 评估Pro-DLI和Pre-DLI对无白血病生存期 (LFS),累积复发发病率 (CIR) 和其他临床结果的影响.
主要方法:
- 对64名接受Pro-DLI (早期,缓解期) 的患者和84名接受Pre-DLI (MRD触发) 的患者的回顾性分析.
- 两组之间的两年LFS,CIR,急性和慢性移植对宿主疾病 (GVHD),非复发死亡率 (NRM) 和整体存活率 (OS) 的比较.
主要成果:
- 与DLI前队列相比,Pro-DLI队列的2年LFS (56.3%对40.5%,P=0.045) 和2年CIR (23.4%对48.8%,P<.001) 显著更高,比DLI前队列更低.
- 支持DLI与慢性GVHD的发病率较高相关 (64.1%与40.5%,P <.001).
- 在PRO-DLI和PRE-DLI组之间,在急性GVHD,NRM或OS中没有观察到显著差异.
结论:
- 早期预防性DLI显著提高了患有耐药性/复发性急性白血病的患者的复发预防和长期无白血病生存率.
- 预防性DLI提供了一种优越的策略,与MRD触发的先发性DLI相比,用于复发管理,尽管慢性GVHD的风险更高.

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.
