概括
患有先前固体瘤 (PST) 病史,因多发性骨髓瘤 (MM) 接受先发性自身造血细胞移植 (autoHCT) 的患者的整体存活率更差. 然而,PST在自动HCT后不会影响无进展生存率或响应率.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 移植医学 移植医学
背景情况:
- 前置自主造血细胞移植 (autoHCT) 是新诊断的多发性骨髓瘤 (MM) 的标准.
- 之前的固体瘤 (PST) 病史是被考虑用于移植资格和风险分层的并发症.
- 在MM中,PST对AutoHCT结果的独立预后影响还没有得到很好的定义.
研究的目的:
- 调查先前固体瘤 (PST) 史对多发性骨髓瘤 (MM) 患者进行前期自身造血细胞移植 (autoHCT) 的结果的独立预后影响.
- 确定PST是否影响MM中自动HCT后的无进展生存率 (PFS) 和总生存率 (OS).
主要方法:
- 对2853名MM患者进行前期自动HCT (1997-2021) 的单中心回顾性分析.
- 患者被分为具有 (PST+) 和没有 (PST-) 之前固体器官恶性瘤的患者.
- 主要终点包括无进展生存率 (PFS) 和总生存率 (OS);进行了多变量分析.
主要成果:
- 10%的患者 (n=274) 在病史中患有PST.
- PST+患者年龄较大,更经常是男性,更有可能患有高风险细胞遗传学.
- 在PST+和PST-组之间没有观察到移植前或移植后反应率或MRD状态的显著差异.
- 中位数PFS是可比的 (36.7个月与39.9个月,P=.31).
- 在PST+组中,中位寿命显著较短 (81.3个月与104.0个月,P=.020).
- 多变量分析证实PST是劣质OS的独立预测因子 (HR1.34,P=.011).
结论:
- 之前的固体瘤 (PST) 病史与多发性骨髓瘤 (MM) 患者的整体存活率 (OS) 较差,这些患者接受了前期自身造血细胞移植 (autoHCT).
- 在MM中,PST似乎没有独立影响无进展生存率 (PFS) 或自动HCT后的响应率.
- 这些发现强调了在接受自动HCT的MM患者的风险分层中考虑PST的重要性.

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.

Tissue Transplantation
316
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.
