概括

早期非小细胞肺癌 (NSCLC) 显示免疫激活,但进展到晚期导致免疫抑制. 了解这些瘤免疫微环境 (TIME) 变化是新NSCLC治疗的关键.

科学领域:

在瘤学瘤学.
免疫学免疫学免疫学
癌症研究癌症研究

背景情况:

瘤免疫微环境 (TIME) 在非小细胞肺癌 (NSCLC) 的进展中起着至关重要的作用.
早期NSCLC发病率的增加需要了解免疫动力学和驱动因素的改变,以改善结果.

研究的目的:

在早期NSCLC的时间分析免疫细胞透和空间分布.
研究与NSCLC进展相关的免疫变化和EGFR突变等特定驱动器变化的研究.

主要方法:

从105名患有NSCLC (癌前病变到III期) 的患者收集了瘤组织.
利用下一代测序 (NGS) 进行驱动器改变和多重免疫光学 (mIF) 进行免疫细胞分析.
分析了免疫细胞密度,百分比和接近癌细胞的情况,包括接受新辅助治疗的患者.

主要成果:

与早期病变相比,I期NSCLC表现出增加的CD8+T细胞,M1巨细胞和未成熟的NK细胞.
EGFR突变与减少的NK细胞和增加的M2巨细胞相关.
从I阶段到III阶段的NSCLC的进展显示CD8+T细胞增加,但也显示了免疫抑制标记物,如PD-L1/PD-1接近性和M1巨细胞减少.

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...
