细胞遗传学上正常的急性髓性白血病 (CN-AML) 的结构变异 (SVs) 确定了一个非常高风险的群体. 这些高风险的SVs (HRVs) 完善预后准确性,并可能指导患者个性化治疗的结果差.
科学领域:
- 血液学 血液学 血液学
- 基因组学就是基因组学.
- 癌症生物学 癌症生物学
背景情况:
- 细胞遗传学和基因组分析指南 根据ELN2022指南对急性髓性白血病 (AML) 的治疗.
- 在细胞遗传学上正常的AML (CN-AML) 中存在显著的结果变异性,突出显示出未满足的临床需求.
- 对于CN-AML患者,需要超出当前分类的预后标志物.
研究的目的:
- 调查强化治疗CN-AML患者结构变异 (SVs) 的预后意义.
- 确定与CN-AML.中不良结果相关的特定SV.
- 评估SVs在CN-AML中提升风险分层的潜力.
主要方法:
- 长期阅读的全基因组测序是在162名CN-AML患者的前性队列上进行的.
- 实体结构变异 (SVs) 被确定并过以获得预后意义.
- 高风险SVs (HRVs) 在一个单独的149名CN-AML患者队列中使用针对性测试进行了验证.
主要成果:
- 在13%的患者中,五种体质性SV被确定为高风险变异 (HRV),与较短的整体存活期 (OS) 和无事件存活期 (EFS) 相关.
- HRVs独立预测了糟糕的结果,即使在患有常见突变的患者中,如FLT3ITD和NPM1mut.
- 人权视频定义了一个"非常高风险"类别,改善了ELN2022框架内的OS预测,并显示了转录放松管制的证据.
结论:
- 结构变异对于细化细胞遗传学上正常的急性髓性白血病的风险分层是有价值的.
- 识别HRV可以精确确定CN-AML患者,结果极为悲惨.
- 这些发现支持开发个性化治疗方法,高风险的CN-AML患者被发现的SVs.

Copy number variations or CNVs are the structural variations that cover more than 1kb of DNA sequence. The single nucleotide polymorphism (SNP), on the other hand, is a single nucleotide change or a point mutation that is found in more than 1%...

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...
