概括
在ALK阳性非小细胞肺癌 (NSCLC) 患者中,长体微管相关蛋白类4 (EML4) -ALK变异与更好的结局和对第二代ALK抑制剂的反应相关. TP53共同突变表明预后较差.
科学领域:
- 在瘤学瘤学.
- 遗传学 是一个遗传学.
- 分子生物学分子生物学
背景情况:
- 阳性ALK非小细胞肺癌 (NSCLC) 显示出不同的结果,尽管预后普遍有利.
- 患者分层需要比ALK阳性更深入的理解.
研究的目的:
- 为了改善ALK阳性NSCLC患者的分层.
- 研究特定的ALK融合变体和同时发生的突变对临床结果的影响.
主要方法:
- 从59名ALK阳性NSCLC患者的临床和病理数据的回顾性分析.
- 下一代测序用于识别ALK融合变体和突变.
- 使用瘤反应和生存指标评估治疗疗效.
主要成果:
- 患有较长EML4-ALK变异的患者 (v1,v2,v8) 的无进展生存期 (PFS) 比患有较短变异的患者 (34 vs. 11个月) 长得多.
- 用第二代ALK抑制剂 (ALKi) 治疗显示PFS优势 (NR与9个月).
- TP53共同突变与较短的整体存活期 (OS) (37个月与NR相比) 有关.
结论:
- 较长的EML4-ALK变异与改善的预后和更好的反应与ALK阳性NSCLC的第二代ALKi有关.
- 在这个患者队列中,TP53共同突变是负预后标志物.

Targeted Cancer Therapies
7.6K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Single Nucleotide Polymorphisms-SNPs
15.0K
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...

Comparing Copy Number Variations and SNPs
17.7K
Sequencing of the human genome has opened up several best-kept secrets of the genome. Scientists have identified thousands of genome variations that exist within a population. These variations can be a single nucleotide or a larger chromosomal variation.
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%...
