概括
在急性髓性白血病 (AML) 患者中,在 haploidentical 干细胞移植 (haplo-HSCT) 之前检测分子可测残留疾病 (mMRD) 可以预测结果. 移植前的mMRD阳性与更差的生存率有关,这表明加强治疗策略可能会改善结果.
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:
- 定量实时聚合酶连锁反应 (qPCR) 和下一代测序 (NGS) 在匹配的造血干细胞移植 (HSCT) 中检测出具有预后价值的分子可测量的残留疾病 (mMRD).
- 关于mMRD检测在急性骨髓性白血病 (AML) 的 haploidentical HSCT (haplo-HSCT) 中的预后作用的数据有限.
研究的目的:
- 为了研究使用qPCR/NGS在AML患者接受Haplo-HSCT的移植前mMRD检测的预后价值.
- 为了比较mMRD阳性和mMRD阴性AML患者在haplo-HSCT后的临床结果.
主要方法:
- 分析了一组148名AML患者的第一次完全缓解 (CR1),他们接受了Haplo-HSCT.
- 患者根据移植前的mMRD状态 (mMRD+与mMRD-) 进行分层,使用PCR/NGS和ELN 2017风险分层.
- 包括整体存活率 (OS),复发累积发生率 (CIR),无白血病存活率 (LFS) 和非复发死亡率 (NRM) 在内的结果在组之间进行了比较.
主要成果:
- 在Haplo-HSCT之前持久的mMRD与AML患者的长期结果明显恶化有关.
- 与mMRD阴性组相比,mMRD阳性组的两年OS和LFS较低 (77.1%的OS,72.7%的LFS) (92.3%的OS,90.7%的LFS).
- 多变量分析证实mMRD阳性是较差的OS和LFS的独立预后因素.
结论:
- 移植前的mMRD检测对接受哈普洛-HSCT的AML患者的结果具有显著的预测价值.
- 在Haplo-HSCT之前mMRD阳性的AML患者经历了劣质的OS和LFS.
- 诸如强化骨髓衰变条件 (MAC),早期降低免疫抑制和捐赠淋巴细胞输液 (DLI) 等策略可能会改善mMRD阳性患者的结果.

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.

Multipotency of Hematopoietic Stem Cells
3.0K
The hematopoietic stem cells or HSCs are multipotent, meaning they can differentiate and give rise to all blood and immune cells. HSCs are maintained in the quiescent stage until an external stimulus initiates their differentiation. The multipotent HSCs exist as two heterogeneous populations, long-term repopulating cells (LTRC) and short-term repopulating cells (STRC). The two HSC populations have different surface markers or receptors and are classified based on quiescence and long-term...

Stem Cell Therapy for Tissue Regeneration
4.0K
Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.
