概括
介素-7受体 (IL7R) 突变与急性髓性白血病 (AML) 患者的较差结果有关. 这些突变与较高的非复发性死亡率以及降低整体和无事件生存率相关,即使在干细胞移植后也是如此.
科学领域:
- 血液学 血液学 血液学
- 在瘤学瘤学.
- 分子生物学分子生物学
背景情况:
- 干白素-7受体 (IL7R) 突变是已知的急性淋巴细胞白血病 (ALL) 的不良预后因素.
- IL7R突变对急性髓性白血病 (AML) 预后的影响不太清楚.
- 这项研究调查了AMLIL7R突变的患病率和临床意义.
研究的目的:
- 在新诊断的AML患者中确定IL7R突变的频率.
- 评估IL7R突变与临床结果之间的关联,包括总生存率 (OS),无事件生存率 (EFS) 和非复发死亡率 (NRM).
- 评估IL7R突变对接受造血干细胞移植 (HSCT) 患者和特定突变亚组 (TET2,DNMT3A) 患者的结果的影响.
主要方法:
- 对346名新诊断的AML患者的分析.
- 一个167基因组的下一代测序.
- 对临床数据和生存结果的回顾性分析.
主要成果:
- 在9.5%的AML患者中发现了IL7R突变.
- 与没有突变的患者相比,具有IL7R突变的患者表现出明显较低的5年OS (51.5%vs72.2%) 和EFS (36.1%vs58.1%),以及较高的NRM (21.4%vs6.2%).
- 即使在接受HSCT和TET2和DNMT3A突变亚组的患者中,IL7R突变也与更糟糕的结果有关.
结论:
- IL7R突变是AML的一个独立的不良预后因素.
- 具有IL7R突变的AML患者面临较低的生存率和较高的NRM.
- 需要进一步的多中心前性研究来证实这些发现.

Rous Sarcoma Virus (RSV) and Cancer
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand RNA genome. Its genome consists of four main open...
