概括
较高的中性细胞与淋巴细胞比率 (NLR) 和红细胞分布宽度 (RDW-CV) 是急性髓性白血病 (AML) 的不良预后标志物. 较低的淋巴细胞与单细胞比率 (LMR) 也表明AML患者的结果更差.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 临床病理学 临床病理学
背景情况:
- 中性粒细胞与淋巴细胞比率 (NLR),淋巴细胞与单细胞比率 (LMR),血小板与淋巴细胞比率 (PLR) 和红细胞分布宽度 (RDW) 的预后意义已在各种血液恶性瘤中确定.
- 急性髓性白血病 (AML) 是一种复杂的血液性恶性瘤,患者的结果具有显著的变化.
研究的目的:
- 调查前治疗中性粒细胞与淋巴细胞比率 (NLR),淋巴细胞与单细胞比率 (LMR),血小板与淋巴细胞比率 (PLR),红细胞分布宽度变化系数 (RDW-CV) 和红细胞分布宽度标准偏差 (RDW-SD) 作为新诊断的AML患者的预后标志物的作用.
- 评估这些标记物与AML患者治疗反应,进展和生存的相关性.
主要方法:
- 进行了一项回顾性队列研究,涉及204名新诊断AML的患者.
- 分析了NLR,LMR,PLR,RDW-CV和RDW-SD的治疗前水平.
- 使用统计模型 (单变量和多变量) 来评估这些标志物的预后值,以评估化疗反应,进展和存活率.
主要成果:
- 在单变量分析中,较高的RDW-CV和较低的LMR与诱导化疗反应较差有关.
- 多变量分析表明,年龄,ECOG得分,细胞遗传风险,NLR和RDW-CV显著影响了对化疗无反应的几率.
- 在单变体分析中,NLR和RDW-CV被确定为进展风险的显著预测因素,而细胞遗传风险,白细胞计数和RDW-CV在多变体环境中影响了无进展生存期 (PFS).
- 单变量分析显示,NLR,LMR和RDW-CV影响了死亡风险,影响了整体生存期 (OS).
结论:
- 升高的NLR,升高的RDW-CV,降低的LMR和潜在的降低的PLR被确定为AML的不良预后因素.
- 这些血液学指数可以帮助诊断出AML的患者的风险分层,并可能指导治疗决策.

Disorders of Leukocytes
820
Leukocyte disorders can lead to either leukopenia, characterized by an abnormally low leukocyte count, or leukocytosis, marked by a very high leukocyte number.
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. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...

Differentiation of Common Myeloid Progenitor Cells
3.2K
Common myeloid progenitors (CMPs) are oligopotent cells that can differentiate into granulocytes and macrophages. Granulocytes and macrophages are essential for protecting the body against bacterial, viral, or fungal infections. They migrate from the bone marrow into the circulating blood to reach specific tissue sites where they differentiate and help in immune surveillance. However, they survive only for a few days and must be continuously made available to the organism to maintain a robust...
