概括
较年轻的平分相同捐赠者 (HID) 可能为接受异性干细胞移植 (allo-HCT) 的老年急性髓性白血病 (AML) 患者提供比较年长的匹配兄弟捐赠者 (MSD) 的优势. 虽然HID的复发率较低,但由于非复发性死亡率较高,整体存活率等结果相似.
科学领域:
- 血液学 血液学 血液学
- 移植免疫学 移植免疫学
- 在瘤学瘤学.
背景情况:
- 同源性造血干细胞移植 (allo-HCT) 选择传统上优先考虑人类白细胞抗原匹配,以匹配的兄弟捐赠者 (MSD) 为首选.
- 年龄较大的急性髓性白血病 (AML) 患者通常有较大的兄弟姐妹,引发了对捐赠者的年龄影响移植结果的担忧.
- 哈普洛相同捐赠者 (HID),如后代,比MSD更容易获得,通常比MSD年轻.
研究的目的:
- 为了比较老年AML患者 (≥60岁) 第一次完全缓解 (CR1) 的allo-HCT的结果,使用年轻的HID (≤40岁) 或老年MSD (≥50岁).
- 评估供体类型 (HID与MSD) 对复发发病率,非复发死亡率 (NRM),移植与宿主疾病 (GvHD) 和生存终点的影响.
主要方法:
- 从EBMT注册数据库中对1247名AML患者 (≥60岁,CR1) 的回顾性分析.
- 患者从MSD (n=721,≥50年) 或HID (n=526,≤40年) 接受了移植.
- HID接受了移植后的环胺;MSD在体内接受了T细胞耗尽用于GvHD预防.
主要成果:
- 单变量分析表明,与MSD相比,HID与复发发病率较低 (p=0.01),但NRM (p=0.01) 和急性GvHD (p=0.01) 较高.
- 多变量分析证实HID的复发较少,但NRM更多.
- 两年总生存率 (OS),无白血病生存率 (LFS) 和无GvHD/无复发生存率 (GRFS) 在HID和MSD组之间相似 (62.5%,56%,47%,分别).
结论:
- 较年轻的HID可以导致较年长的AML患者的复发率降低,与较年长的MSD相比,在CR1中接受alo-HCT的老年AML患者中.
- 在HID组中,较高的NRM抵消了较低复发的好处,导致可比的整体存活率和LFS.
- 这项研究表明,虽然捐赠者的年龄和类型会影响特定的结果,但在这个患者群体中,在年轻的HID和老的MSD之间,整体存活率可能不会显著不同.

Kidney Transplant I: Introduction
64
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...

Tissue Transplantation
524
Tissue transplantation is a significant medical procedure involving the transfer of cells, tissues, or organs from a donor to a recipient, with the primary aim of restoring lost functions. This procedure is crucial in treating a broad spectrum of diseases, including kidney diseases, liver failure, heart disease, and certain types of cancers.
