1268-可解释深度学习辅助胃癌预后及化疗获益预测研究

from 聊聊Sci

这份研究报告介绍了一种利用弱监督Transformer深度学习架构开发的可解释生物标志物——病理风险评分(TPRS),旨在提升胃癌的预后评估与精准治疗。研究团队分析了数千张全切片数字化病理图像(WSIs),证明了TPRS能有效预测患者的总生存期,并能识别出能从术后辅助化疗中显著获益的II-III期患者。该模型不仅在内部数据集和TCGA外部验证集中表现出稳健的独立预后价值,还克服了深度学习“黑箱”局限性。通过构建“基因→细胞特征→TPRS”的中介分析框架,研究揭示了影像特征与转录组学及免疫微环境之间的生物学联系。这一成果为胃癌的个体化诊疗决策提供了一个低成本、高效率且具有生物学解释力的数字化工具。References:Ji J, Zhang X, Hua M, et al.
