概括

非小细胞肺癌 (NSCLC) 中的CD47表达与预后较差和瘤相关的巨细胞透增加有关. 这一发现表明CD47可能作为一个有价值的生物标志物来预测NSCLC患者的结果.

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:

非小细胞肺癌 (NSCLC) 对健康构成重大负担,往往在晚期诊断出来.
有效的预后分层和生存改善策略对于管理NSCLC至关重要.
免疫检查点是理解和潜在治疗NSCLC的关键目标.

研究的目的:

为了评估NSCLC组织中CD47的表达水平.
确定CD47表达和瘤相关巨细胞 (TAM) 透在NSCLC中的关系.
评估CD47在NSCLC患者的预后意义.

主要方法:

对50名NSCLC患者的回顾性分析.
免疫组织化学和共聚焦显微镜用于CD47表达的评估.
在T淋巴细胞上检测CD47的免疫光;用于生存分析的Kaplan-Meier和Cox回归;用于CD47相互作用的近距离结合试验 (PLA).

主要成果:

与相邻组织相比,NSCLC瘤组织中的CD47表达显著更高 (52%对20%).
CD47阳性与淋巴结转移,晚期临床阶段和差异化相关,作为独立的风险因素.
在CD47阳性NSCLC中观察到TAM透率增加,与患者存活时间缩短有关.

结论:

CD47表达是NSCLC预后不佳的重要指标.
增加的CD47水平与增加的TAM透有关,这表明它在免疫逃避中发挥了作用.
CD47具有作为预后生物标志物和NSCLC治疗的治疗点的潜力.

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...
