下一代测序 (NGS) 在各类卵巢癌中确定了不同的致癌途径. 针对这些途径可能会改善患者的治疗结果,特定的途径与无进展和整体存活相关.
科学领域:
- 在瘤学瘤学.
- 基因组学就是基因组学.
- 分子生物学分子生物学
背景情况:
- 卵巢癌包括多种不同的组织学亚型,预后不同.
- 识别关键的致癌途径对于理解瘤发育和进展至关重要.
- 下一代测序 (NGS) 提供了一种全面的方法来分析癌症基因组.
研究的目的:
- 通过使用NGS来确定不同卵巢癌组织学类型中占主导地位的瘤性途径.
- 调查已识别的致癌途径与临床预后 (无进展生存率和整体生存率) 之间的相关性.
主要方法:
- 对420名接受NGS测试的卵巢癌患者进行了回顾性分析.
- 识别的突变被分类为七个主要的致癌途径.
- 途径参与与患者生存结果之间的相关性分析.
主要成果:
- 高度血清癌 (HGSC) 和癌瘤中TP53突变是主要的.
- 在低度血清癌和粘膜癌中,MAP激酶信号占主导地位.
- PI3K-AKT-mTOR和SWI/SNF通路在子宫内膜癌和透明细胞癌中很常见.
- 在HGSC中,DNA损伤反应途径的参与与更好的无进展生存率 (PFS) 相相关.
- 在HGSC.中,RTK信号通路的参与与更好的整体存活率 (OS) 相相关.
结论:
- 基于NGS的基因分析可以指导卵巢癌的向治疗策略.
- 特定的致癌途径与不同的组织学亚型和临床结果有关.
- 需要进一步的研究来阐明RTK信号与改进的操作系统之间的关联背后的机制.

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...

Cancer-Critical Genes I: Proto-oncogenes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
