概括
慢性移植对宿主疾病 (cGVHD) 在异质造血干细胞移植 (allo-HCT) 后显著增加非复发性死亡率. 这种风险在老年和年轻患者群体中是一致的,突出显示了cGVHD.
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:
- 全基性造血干细胞移植 (allo-HCT) 是各种血液恶性瘤和其他疾病的拯救生命的程序.
- 慢性移植对宿主疾病 (cGVHD) 仍然是HCT后的发病率和死亡率的主要原因.
- 越来越多的老年人正在接受alo-HCT,需要了解与年龄相关的结果.
研究的目的:
- 评估cGVHD在alo-HCT后对患者结果的影响.
- 为了比较cGVHD对老年 (≥60岁) 和年轻 (<60岁) 成人患者的结果的影响.
主要方法:
- 在1999年至2018年期间接受alo-HCT的患者的回顾性分析.
- 在移植后的+180日对cGVHD发育的评估.
- 结果的比较,包括非复发性死亡率 (NRM),与没有cGVHD的患者之间,按年龄分层.
主要成果:
- 在+180日之前患有cGVHD的患者与没有cGVHD的患者相比,NRM的风险和发病率显著增加.
- 在患有cGVHD的老年患者和年轻患者之间没有观察到结果的显著差异.
- 不管患者的年龄,cGVHD与严重的发病率有关.
结论:
- cGVHD是不利结果的关键决定因素,特别是NRM,在 allo-HCT 后.
- 对cGVHD对alo-HCT结局的有害影响并没有受到患者年龄 (≥60 vs <60岁) 的显著影响.
- 缓解cGVHD的策略对于改善异构移植受体的存活率至关重要.

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.

Comparing the Survival Analysis of Two or More Groups
177
Survival analysis is a cornerstone of medical research, used to evaluate the time until an event of interest occurs, such as death, disease recurrence, or recovery. Unlike standard statistical methods, survival analysis is particularly adept at handling censored data—instances where the event has not occurred for some participants by the end of the study or remains unobserved. To address these unique challenges, specialized techniques like the Kaplan-Meier estimator, log-rank test, and...

Tissue Transplantation
358
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.
