概括

在患有肺腺癌的老年男性中,KRAS突变更常见. 与混合或固体不透明度相比,CT纹理特征如纯地玻璃不透明度 (pGGO) 与较低的KRAS突变率有关.

科学领域:

在瘤学瘤学.
放射学放射学是一门学科.
遗传学是一个遗传学.

背景情况:

基尔斯顿大鼠肉瘤病毒瘤基因同源 (KRAS) 是肺腺癌 (LUAD) 的关键瘤驱动因素.
在LUAD患者中,KRAS突变与计算机断层扫描 (CT) 纹理特征之间的相关性尚未得到充分证实.
这项研究研究了CT纹理特征与LUAD中KRAS突变状态之间的关系.

研究的目的:

研究CT纹理特征与LUAD中的KRAS突变状态之间的关联.
为了确定特定的CT成像特征是否与KRAS突变的存在相关.
提供关于LUAD放射基因组景观的见解.

主要方法:

对720名患有手术前胸部CT的LUAD患者的回顾性分析,来自808名接受手术切除的患者的CT数据.
根据纹理特征对病变的CT图像进行分类.
评估KRAS突变状态,临床特征和CT纹理特征之间的关联.

主要成果:

在男性 (8.5%) 和老年 (6.5%) 的LUAD患者中,KRAS突变更为频繁.
混合磨砂玻璃不透明度 (mGGO) 与纯磨砂玻璃不透明度 (pGGO) 和纯固体不透明度 (pSO) 相比,KRAS突变的发生率较低.
一个趋势表明,KRAS突变的pGGO频率较高,而野生类型的病变≤1厘米,尽管在统计学上并不显著.

结论:

KRAS突变在男性和老年LUAD患者中更为普遍.
CT纹理特征,特别是从pGGO到pSO的进展,可能与LUAD中的KRAS突变状态有关.
需要进一步的研究来探索这些发现的放射遗传学影响.

Abnormal Proliferation

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...

Tumor Progression

Tumor Progression

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...
