概括

这项研究表明,胰腺管腺癌 (PDAC) 刚性与特定的病理特征和免疫细胞透有关. 术前治疗软化PDAC并改变这些关联,建议新的治疗点.

科学领域:

在瘤学瘤学.
生物物理学的生物物理.
免疫学免疫学免疫学

背景情况:

胰腺管道腺癌 (PDAC) 的特点是身体硬度和预后不佳.
了解PDAC的物理和病理特征之间的联系对于阐明癌症机制至关重要.

研究的目的:

为了比较PDAC组织与其他瘤的性.
研究PDAC瘤硬度及其病理和免疫特征之间的关联.
评估手术前治疗对PDAC硬度及其与瘤微环境的关系的影响.

主要方法:

对93名接受彻底手术的PDAC患者的身体和病理特征的分析.
使用多重光免疫组织化学评估免疫性瘤微环境.
瘤刚度,原蛋白含量和免疫细胞密度 (CD8+ T细胞,CD204+巨细胞) 之间的相关性分析.

主要成果:

PDAC度与阿赞-马洛里染色,α-光滑肌动蛋白和 I. 原蛋白具有积极的相关性.
在没有手术前治疗的情况下,瘤硬与PDAC中的CD8+ T细胞和CD204+巨细胞密度有关.
与未经治疗的PDAC相比,接受了手术前治疗的PDAC表现出降低了硬度和改变了免疫细胞透模式.

结论:

这项研究在人类PDAC的物理性质 (硬度) 和免疫特征之间建立了新的联系.
瘤硬性会影响瘤中心内的免疫细胞分布,特别是在未经治疗的PDAC中.
术前治疗显著改变了PDAC的物理和免疫格局,突出了其治疗潜力.

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...
