在诊断时慢性髓性白血病 (CML) 患者的额外细胞遗传异常 (ACA) 与较差的结局有关. 高风险的ACA显著降低无事件和无进展的生存率,强调在CML管理中需要细胞遗传风险评估.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 遗传学 遗传学 是一个
背景情况:
- 慢性髓性白血病 (CML) 是一种骨髓增殖性瘤.
- 诊断时的细胞遗传异常可能会影响CML的预后.
- 欧洲白血病网 (ELN) 为CML管理提供了应对标准.
研究的目的:
- 调查诊断时的额外细胞遗传异常 (ACA) 及其在中国CML患者的临床后果之间的相关性.
- 评估高风险ACA对生存结果和分子响应率的预后影响.
主要方法:
- 对337名中国CML患者进行了回顾性观察队列研究.
- 使用欧洲白血病网络标准分析无事件生存 (EFS) 和无进展生存 (PFS).
- 多变量考克斯回归分析以确定PFS和主要分子响应 (MMR) 的独立预测因子.
主要成果:
- 在诊断时,在12.2%的患者中发现了额外的细胞遗传异常 (ACA),其中24例是高风险ACA.
- 与没有ACA或具有低风险ACA的患者相比,患有高风险ACA的患者表现出明显较低的分子响应率,EFS (45.8%) 和PFS (54.2%).
- 高风险的ACA和EUTOS长期生存率 (ELTS) 分数是MMR和PFS的独立预后因素.
结论:
- 诊断时的细胞遗传评估对于CML风险分层至关重要.
- 整合基于细胞遗传学的风险,包括高风险的ACA和ELTS得分,可以提高CML患者的预后准确性.
- 这些发现支持将细胞遗传风险评估纳入CML管理策略.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes.
