概括

患有ATRX突变或多叶性转移的乐髓肉瘤 (LMS) 患者的存活率较差. 转移性模式在子宫和非子宫LMS之间有所不同,影响预后.

科学领域:

在瘤学瘤学.
遗传学是一个遗传学.
病理学病理学病理学

背景情况:

溶性肌肉瘤 (LMS) 是一种罕见的软组织肉瘤,预后因素尚不清楚.
瘤基因组学和转移模式在LMS预后中至关重要,但不完全定义.

研究的目的:

调查LMS患者的瘤突变,转移部位和生存结果之间的关联.
确定特定的基因组变化和转移模式,预测LMS的预后.

主要方法:

对110名LMS患者进行了基因组测试的回顾性队列研究.
分析瘤突变,转移部位和存活率 (总体存活率,无进展存活率/无复发存活率).
卡普兰-梅尔和考克斯的比例危险回归模型被用于生存分析.

主要成果:

TP53和RB1是最常见的突变;肺和肝脏是最常见的转移部位.
ATRX突变和多发性转移独立地与较低的整体存活率 (OS) 相关.
在子宫和非子宫LMS之间观察到明显的转移模式.

结论:

在LMS中,ATRX突变和多发性转移是不良的预后指标.
转移性模式在子宫和非子宫LMS之间有显著差异.

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...
