概括

由于瘤的多样性,卵巢癌的免疫治疗具有挑战性. 空间分析揭示了免疫模式,可以预测免疫疗法目标和患者的结果,指导个性化治疗策略.

科学领域:

在瘤学瘤学.
免疫学免疫学免疫学
病理学病理学病理学

背景情况:

免疫疗法在卵巢癌 (OC) 中表现出有限的成功,这是由于显著的瘤异质性和可变的免疫反应.
瘤免疫微环境 (TIME) 分析为OC患者的分层和优化治疗选择提供了一个潜在的策略.

研究的目的:

使用数字空间分析 (DSP) 在OC中描述空间上不同的TIME表型.
评估免疫透模式是否可以预测免疫瘤学标的存在,并与临床结果相关.

主要方法:

使用数字空间分析 (DSP) 来分析OC样本中的TIME.
图像分析被用来描述免疫透模式和瘤内的空间相互作用.

主要成果:

扩散性免疫透和增加的瘤免疫空间相互作用与IDO1,PD-L1,PD-1和Tim-3的更高表达相关.
焦点免疫与CD163巨细胞和较差的初步结果有关.
免疫排除与Tregs和Fibronectin的存在有关.
高度血清性OC表现出更强的免疫反应和更容易准的检查点.
低度血清性OC显示扩散透和高STING表达;子宫内膜性OC具有更多的CTLA-4.
粘性和透明细胞OC的特征是焦点免疫群和免疫排除区域,粘性瘤具有富含T细胞的利基.

结论:

在OC中空间上不同的TIME表型与特定的免疫细胞种群和免疫瘤学点的存在有关.
免疫透模式可以为治疗选择提供信息,并预测卵巢癌的结果.
DSP是剖析OC复杂的时间和识别潜在的治疗策略的一个有价值的工具.

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...
