1284-雌激素受体阳性乳腺癌空间免疫组化与化疗预后研究

from 聊聊Sci

这份研究通过空间转录组学和空间蛋白质组学技术,深入探讨了ER+HER2-型乳腺癌的免疫微环境特征。研究人员发现,肿瘤的间质(基质)与上皮区域存在不同的免疫状态,且这些状态与传统的基因组风险评分(Oncotype Dx RS)并不完全同步。关键发现指出,在中等风险患者中,间质细胞毒性T细胞(sTIL CD8+)的高密度与化疗后的不良预后显著相关。这意味着该指标可作为一种预测性生物标志物,帮助临床医生识别哪些患者可能无法从化疗中获益,甚至可能因化疗受损。通过对全切片样本的验证,研究进一步证实了免疫表型分析在优化辅助化疗决策中的巨大潜力。最终,该研究挑战了此类癌症是“免疫冷肿瘤”的传统观点,揭示了免疫浸润在指导个性化治疗中的核心价值。References:Kinsella Z, Jahangir C A, Nyarko H N, et al.
