概括
这项研究发现,基于循环胺的疗法,有或没有博特佐米布,在多发性骨髓瘤患者中产生更多的干细胞. 这些疗法在干细胞动员和采集方面是有效的.
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:
- 在多发性骨髓瘤中,干细胞调动通常使用G-CSF与或没有循环胺 (Cy) 化疗或Plerixafor.
- 临床前研究表明,蛋白酶体抑制剂可以帮助动员.
- 以前的研究结果表明,博特佐米布 (Bort) 加Cy可以改善干细胞产量.
研究的目的:
- 为了比较四种不同的干细胞调动方案在多发性骨髓瘤患者的疗效.
- 为了确定在第一个表中达到CD34+剂量≥5×10^6/kg的患者的比例.
- 评估跨方案的中位数CD34+产量,总干细胞产量和调动失败率.
主要方法:
- 从2007年9月到2022年12月,对200名多发性骨髓瘤患者 (年龄在18-65岁) 进行了干细胞调动的回顾性分析.
- 评估了四种动员方案:博尔特佐米布+G-CSF (第一组),G-CSF+普莱里克萨福 (第二组),博尔特佐米布-环胺-G-CSF (第三组),环胺+G-CSF (第四组).
- 治疗意图分析的重点是CD34+细胞产量和动员失败.
主要成果:
- 在第一次非中,患者中达到≥5×10^6CD34+细胞/kg的比例分别为26%,53%,69%和63% (p=0.0001).
- 第一次收获的CD34+产量的中位数为3.62,5.20,6.04和6.05 × 10^6/kg (p=0.00004).
- 总干细胞产量的中位数为5.73,6.17,9.14和8.23 × 10^6/kg (p<0.00001),其中第3组的产量最高. 动员失败率分别为7%,3%,0%和2% (p=NS).
结论:
- 与Bortezomib或不含Bortezomib的循环胺基化疗方案,与G-CSF + Plerixafor相比,提供更高的总干细胞产量.
- 这些疗法可与G-CSF + Plerixafor对单次阿菲雷斯产量进行比较.
- 将博尔特佐米布添加到基于环胺的疗法中,可能会进一步增强多发性骨髓瘤的干细胞收集.

Stem Cell Therapy for Tissue Regeneration
4.2K
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.

Differentiation of Common Myeloid Progenitor Cells
3.3K
Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...
