概括
使用移植后循环胺 (PTCy) 的哈普洛同一干细胞移植 (haploSCT) 对印度的癌症患者显示出希望. 虽然生存率令人鼓舞,但感染和移植与宿主疾病 (GVHD) 仍然是需要谨慎管理的重大挑战.
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:
- 一致性干细胞移植 (haploSCT) 是缺乏匹配供体的患者的替代方案.
- 移植后循环胺 (PTCy) 已成为减轻哈普洛SCT中的移植对宿主疾病 (GVHD) 的关键策略.
- 印度使用PTCy的HaploSCT的结果,特别是在专门的癌症中心,需要详细的评估.
研究的目的:
- 评估印度一家癌症医院用移植后环酸 (PTCy) 进行的平分相同干细胞移植 (haploSCT) 的结果.
- 分析移植体排斥,复发,GVHD和感染的发生率.
- 为了确定存活率,并确定在接受HaploSCT的患者死亡的主要原因.
主要方法:
- 在2015年3月至2022年8月期间,对101个哈普洛SCT进行了回顾性分析.
- 患者接受了骨髓缩性 (MA),非骨髓缩性 (NMA) 或降低强度调节 (RIC).
- 评估的结果包括移植,移植排斥,复发,GVHD,感染,非复发死亡率和整体存活 (OS).
主要成果:
- 99名患者 (95名恶性,4名非恶性) 接受了101次哈普洛SCT.
- 中性粒细胞和血小板移植的中位时间分别为15天和15.5天.
- 急性GVHD发生在32.6%,初级移植排斥发生在8.9%,复发发生在17.8%.
- 常见的感染包括BK病毒 (47.3%) 和细胞巨乳病毒 (CMV; 65.3%).
- 一年和两年的OS率分别为56.7%和49.3%.
- 败血症 (56.2%),复发 (22.2%),GVHD (8.8%) 是主要的死亡原因,非复发死亡率为37.3%.
结论:
- 与PTCy一起的哈普罗同一干细胞移植 (haploSCT) 为印度的患者提供了可行的治疗选择,具有合理的存活率.
- 感染,特别是像BK和CMV这样的病毒感染,以及急性GVHD仍然是移植后的重大挑战.
- 需要进一步的策略来优化感染控制和GVHD预防,以改善HaploSCT的结果.

Stem Cell Culture

Stem cell research aims to find ways to use stem cells to regenerate and repair cellular damage. Over time, most adult cells undergo the wear and tear of aging and lose their ability to divide and repair themselves. Stem cells do not display a particular morphology or function. Adult stem cells, which exist as a small subset of cells in most tissues, keep dividing and can differentiate into a number of specialized cells generally formed by that tissue. These cells enable the body to renew and...

Stem Cell Therapy for Tissue Regeneration
3.8K
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.
