概括
自主干细胞移植 (ASCT) 之前的降低强度调节 (RIC) 是老年扩散型大B细胞淋巴瘤患者的可行选择,在调整混因素后,其结果与标准强度调节 (SIC) 相似.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 临床医学 临床医学
背景情况:
- 高剂量化疗后进行自身干细胞移植 (HDCT/ASCT) 是扩散型大B细胞淋巴瘤 (DLBCL) 的标准治疗方法.
- HDCT/ASCT与显著的毒性有关,特别是在老年或医学上脆弱的患者中.
- 减少强度调节 (RIC) 方案已开发,以减轻与治疗相关的发病率.
研究的目的:
- 在接受ASCT的老年DLBCL患者中,与标准强度调节 (SIC) 相比,评估RIC的疗效和安全性.
- 确定影响该患者群体结果的因素.
主要方法:
- 对146名年龄在60岁及以上的DLBCL患者的回顾性分析,这些患者在2005年至2019年期间接受了治疗.
- 患者被分为两组:86人接受SIC (BEAM/TEAM) 和60人接受RIC (包括BCNU,梅尔法兰,蒂奥特帕,布苏尔凡,班达穆斯丁在内的各种方案).
- 毒性,非复发死亡率 (NRM),复发率,无进展生存率 (PFS) 和整体生存率 (OS) 的比较.
主要成果:
- 在SIC和RIC组之间,毒性是可比的.
- 三年累计复发发病率在RIC组 (30.8%) 与SIC组 (23.4%) (p=0.034) 相比较高.
- 没有观察到NRM的显著差异. 单变量分析显示SIC具有优越的PFS,但多变量分析显示PFS没有显著差异,并且RIC具有更好的OS的趋势.
- 预测更好的生存状况的因素包括RIC,60-69岁,ECOG0,非重的疾病和先前的1线治疗.
结论:
- 在ASCT之前的RIC在老年DLBCL患者中似乎是可行的.
- 虽然单变量分析有利于PFS的SIC,但多变量分析建议可比的PFS和RIC的潜在OS好处,当调整为混因素时.
- 年龄,表现状况和疾病特征显著影响ASCT接受的老年DLBCL患者的生存结果.

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 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.
