1143-三阴性乳腺癌的空间转录组异质性与临床意义

from 聊聊Sci

这项研究利用空间转录组学技术,深入剖析了三阴性乳腺癌 (TNBC) 复杂的组织结构及其微环境。通过对92名患者样本的分析,研究者揭示了肿瘤与基质成分在分子分型中的不同贡献,并开发出一种能有效预测免疫治疗效果的30基因三级淋巴结构 (TLS) 签名。研究进一步识别出14种跨病患共享的空间分子模式,并将其整合为9种具有临床意义的空间原型 (SA)。这些原型不仅反映了肿瘤内部的高度异质性,还与患者的预后生存和潜在的治疗靶点密切相关。该成果为优化三阴性乳腺癌的个体化精准治疗提供了重要的理论依据与数据支持。References:Wang X, Venet D, Lifrange F, Larsimont D, Rediti M, Stenbeck L, Dupont F, Rouas G, Garcia AJ, Craciun L, Buisseret L, Ignatiadis M, Carausu M, Bhalla N, Masarapu Y, Villacampa EG, Franzén L, Saarenpää S, Kvastad L, Thrane K, Lundeberg J, Rothé F, Sotiriou C.
