研究目的: |
本研究以本院已存的 FFPE 结直肠癌样本为基础,通过多重免疫荧光(mIF)与数字病理学方法,系统比较 MSS 与 MSI 结直肠癌肿瘤微环境(TME)中免疫细胞组成、极化状态与空间分布的差异,重点聚焦 M2 型巨噬细胞极化的量化与空间学特征,进而评估其是否是导致 MSS 型结直肠癌对免疫检查点抑制剂(ICI)耐药的关键组织学因素,并探索其作为预后/疗效预测标志物与潜在干预靶点的可行性。 |
||||||||||||||||||||||
|
Objectives of Study: |
Based on the existing FFPE colorectal cancer samples in our hospital, this study systematically compared the differences in the composition, polarization state and spatial distribution of immune cells in the tumor microenvironment (TME) of MSS and MSI colorectal cancer through multiplex immunofluorescence (mIF) and digital pathology methods. The focus is on the quantitative and spatial characteristics of M2-type macrophage polarization, and then to evaluate whether it is a key histological factor leading to resistance to immune checkpoint inhibitors (ICI) in MSS-type colorectal cancer, and to explore its feasibility as a prognostic/therapeutic predictive marker and potential intervention target. |
