663-三阴性乳腺癌微环境时空演变与免疫治疗响应预测

from 聊聊Sci

这份研究通过分析TONIC临床试验中103名转移性三阴性乳腺癌患者的纵向样本,揭示了肿瘤微环境动态演变与免疫治疗效果的关系。研究团队利用高分辨率的多重成像技术和开源分析管道SpaceCat,从原发灶及治疗前后的转移灶中提取了超过800项空间特征。实验结果表明,治疗中采集的样本比初始样本具有更强的疗效预测能力,其多变量预测模型的准确率(AUC)高达0.90。肿瘤边缘的T细胞浸润、免疫细胞多样性以及骨髓细胞上的PDL1表达被确定为关键的预测指标。相比之下,传统的全外显子测序特征未能展现出可靠的预测价值。这项工作强调了空间蛋白组学在解析复杂免疫反应中的重要性,为优化转移性癌症的精准医疗提供了科学依据。References: Greenwald N F, Nederlof I, Sowers C, et al.
