168-SHR-A1811疗效的空间生物标志物与预测模型

21 Oct 2025

Description

这篇文章介绍了一项针对HER2阳性乳腺癌患者使用新型抗体药物偶联物(ADC)SHR-A1811进行新辅助治疗的转化研究。研究利用多组学数据,包括基因组学、转录组学和先进的空间分析技术,旨在识别预测治疗反应的生物标志物。研究发现,治疗效果与肿瘤微环境(TME)的特征,特别是细胞毒性T细胞的数量和分布,以及HER2强阳性肿瘤细胞的空间聚集模式有关,这些关联在激素受体(HR)阴性和阳性亚组中表现出不同的机制。最后,研究人员开发了一个基于人工智能的预测模型,结合临床病理特征和数字病理图像,用于预测SHR-A1811和其他新型ADC的疗效。References: Ma D, Dai L J, Wu X R, et al.
