概括

这项研究比较了肺腺癌 (LUAD) 与表皮生长因子受体 (EGFR) 突变L858R和19DEL. 19DEL突变与年轻患者和高度瘤有关,而L858R突变在GGO-LUAD中显示出更快的生长但更慢的凝固.

科学领域:

在瘤学瘤学.
遗传学是一个遗传学.
肺部医学肺部医学

背景情况:

肺腺癌 (LUAD) 是全球癌症相关死亡的主要原因之一.
表皮生长因子受体 (EGFR) 突变是LUAD病变的关键驱动因素.
特定的EGFR突变,如L858R和19DEL,影响瘤的行为和治疗反应.

研究的目的:

为了数学地比较肺腺癌 (LUAD) 与特定的表皮生长因子受体 (EGFR) 突变:L858R和19DEL.
分析基于EGFR突变状态的瘤大小和频率比率之间的相关性.
调查L858R与19DEL突变的LUAD的不同生长和固化速率.

主要方法:

分析了1980例手术切除的LUAD病例,包括1195例GGO-LUAD和785例纯固体LUAD (pSD-LUAD).
基于EGFR突变状态的LUAD病例的分组 (L858R与19DEL).
应用多变量逻辑回归和指数方程来分析瘤特征和生长模式.

主要成果:

19DEL突变与年轻个体 (OR: 1.60) 和高度瘤 (OR: 1.46) 有显著的关联.
用指数式方程来描述不同LUAD亚型的瘤大小和频率比之间的关系.
多变量逻辑回归显示了19DEL突变与患者年龄和瘤等级的明显关联.

结论:

与19DEL突变相比,具有L858REGFR突变的纯磨砂玻璃不透明LUAD (pGGO-LUAD) 的生长速度更快.
然而,L858R突变GGO-LUAD的凝固率低于19DEL突变GGO-LUAD的凝固率.
这些发现突显了L858R和19DEL EGFR突变在LUAD中的差异性生长动态.

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...
