概括
多发性骨髓瘤患者的稳定状态干细胞动员是安全的,但效果不佳,需要更多的plerixafor,导致相比化疗收集的细胞较少. 化疗动员导致了更多的感染,但结果更好.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 干细胞移植 干细胞移植
背景情况:
- 高剂量化疗与自身造血干细胞支持是多发性骨髓瘤 (MM) 的标准治疗方法.
- 对比干细胞动员策略对于优化MM患者护理至关重要.
研究的目的:
- 在匈牙利MM患者中,比较稳定状态与化疗基干细胞调动的疗效和安全性.
- 评估干细胞采集成功率,细胞产量,感染发生率和成本效益.
主要方法:
- 一项对接受干细胞调动 (2018-2022) 的210名MM患者的回顾性研究.
- 患者接受了单独的粒细胞殖民地刺激因子 (G-CSF) (稳定状态,n=104) 或化疗后的G-CSF (基于化疗,n=106).
- 关键结果包括动员成功,干细胞产量,感染率和住院时间.
主要成果:
- 与化疗相比,稳定状态调动的plerixa使用率更高 (45%对13%),成功率更低 (11%对3%),干细胞产量减少 (6.9对9.8×10^6细胞/毫升).
- 在稳定状态组中,感染的频率较低 (4%vs27%),住院时间较短 (6vs14天).
- 在先前接受过莱纳利多米德或达拉图穆马布治疗的患者中,plerixafor的使用率更高.
结论:
- 稳态干细胞调动是MM患者的安全程序.
- 然而,它对plerixafor的更高依赖和更低的成功率挑战了它对基于化疗的动员的优越性.
- 化疗动员,尽管感染率较高,但产生更好的干细胞采集结果.

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.

Bone Marrow Sampling and Transplants

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.

Mesenchymal Stem Cells
4.7K
Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...
