概括

脊髓星细胞瘤 (SCAs) 具有H3 K27M变异,其传播率为85%,明显高于野生类型的SCAs. 这些变化和其他高级特征与较差的结果和中枢神经系统扩散的增加有关.

科学领域:

神经瘤学神经瘤学
病理学病理学病理学
临床神经学临床神经学

背景情况:

脊髓星细胞瘤 (SCAs) 具有传播至中枢神经系统 (CNS) 的高风险.
关于SCA传播的发生率和模式的全面数据是有限的.
了解传播对于预测预后和指导治疗至关重要.

研究的目的:

确定中枢神经系统在SCAs中传播的发生率和模式.
确定与SCA传播相关的因素.
分析传播对患者治疗结果的影响.

主要方法:

根据2021年世卫组织分类,对94名SCAs患者 (2011-2022) 的回顾性分析.
评估中枢神经系统的传播 (乳腺膜扩散/子arachnoid播种).
对临床和病理特征的分析,包括H3 K27的改变,组织病理等级,Ki-67指数和瘤长度.

主要成果:

观察到一个总体5年中枢神经系统传播率为85.0%.
与H3 K27野生型 (68.0%,p=0.002) 相比,H3 K27变异患者的5年传播率 (95.2%) 显着更高.
H3 K27M改变,更高的等级,Ki-67指数 (≥10%),和瘤长度 (≥4段) 与扩散增加和传播后生存时间缩短有关.

结论:

H3 K27M变异,较高的组织病理学等级,Ki-67指数升高和瘤长度增加是较高SCA恶性瘤和传播风险的指标.
在SCAs中中枢神经系统传播与患者不良结果有很强的相关性.

The Tumor Microenvironment

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Metastasis

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
