概括
BRAF突变不会显著影响早期肺腺癌 (LUAD) 的预后. 这项研究发现BRAF状态与I阶段LUAD患者的无复发生存率之间没有关联.
科学领域:
- 在瘤学瘤学.
- 基因组学就是基因组学.
- 癌症研究 癌症研究
背景情况:
- 关于V-Raf小鼠肉瘤病毒性瘤基因同类B1 (BRAF) 突变在早期肺腺癌 (LUAD) 的预后作用的数据有限.
- 了解BRAF突变患病率及其影响对于LUAD的治疗策略至关重要.
研究的目的:
- 在I阶段的LUAD患者中调查BRAF突变的比例和临床病理特征.
- 为了确定BRAF突变对I阶段LUAD无复发生存 (RFS) 的预后意义.
主要方法:
- 来自cBioPortal的431名I阶段LUAD患者和上海肺部医院的1604名LUAD患者的分析.
- 使用卡普兰-梅尔曲线,日志等级测试,考克斯比例危险模型,倾向-得分匹配 (PSM) 和重叠权重 (OW) 进行生存分析.
- 评估的主要终点是无复发生存期 (RFS).
主要成果:
- 在5.6%的高加索人群中发现了BRAF突变;在1.4% (高加索人) 和1.0% (中国人) 的患者中发现了BRAF V600E突变.
- 在I阶段LUAD患者 (HR=1.111,p=0.885) 中,即使在PSM和OW之后,也没有发现BRAF突变和更糟糕的RFS之间的显著联系 (HR=1.111,p=0.885).
- BRAF V600E突变状态也缺乏对RFS的预测意义.
结论:
- BRAF突变状态似乎不是第一阶段肺腺癌的预后的重要预测因素.
- 需要进一步的研究和更大的数据集来验证这些发现及其临床影响.

The Ras Gene
6.2K
The Ras-gene-encoded proteins are regulators of signaling pathways controlling cell proliferation, differentiation, or cell survival. The Ras-gene family in humans constitutes three primary members—the HRas, NRas, and KRas. These genes code for four functionally distinct yet closely related proteins—the HRas, NRas, KRas4A, and KRas4B. The involvement of mutant Ras genes in human cancer was first discovered in 1982 and is among the most common causes of human tumorigenesis.

Tumor Progression
6.3K
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
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
8.9K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
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.
