AI总结:

提出切片级基础模型Threads,通过多模态学习在47171对H&E染色切片与基因组数据上预训练,在54项肿瘤学任务中表现优于基线,展现出卓越的泛化能力和标签效率。

摘要:

基础模型正在重塑计算病理学,通过实现迁移学习,在庞大数据集上预训练的模型可适应下游诊断、预后和治疗反应任务。尽管取得了这些进展,基础模型在不进行额外训练的情况下编码整个千兆像素全切片图像的能力仍然有限,且通常缺乏互补的多模态数据。在此,我们引入了Threads,这是一种能够生成任意大小全切片图像通用表示的切片级基础模型。Threads使用多模态学习方法在包含47,171张苏木精和伊红(H&E)染色组织切片的多样队列上进行了预训练,并配以相应的基因组和转录组谱——这是迄今为止用于基础模型开发的最大配对数据集。这种独特的训练范式使Threads能够捕获组织潜在的分子组成,从而产生适用于广泛下游任务的强大表示。在涵盖54项肿瘤学任务的广泛基准测试中,包括临床亚型分类、分级、突变预测、免疫组化状态判定、治疗反应预测和生存预测,Threads优于所有基线,同时展现出卓越的泛化能力和标签效率。它特别适合预测罕见事件,进一步凸显了其临床实用性。我们打算将该模型向更广泛的社区公开发布。

英文摘要:

Foundation models are reshaping computational pathology by enabling transfer learning, where models pre-trained on vast datasets can be adapted for downstream diagnostic, prognostic, and therapeutic response tasks. Despite these advances, foundation models are still limited in their ability to encode the entire gigapixel whole-slide images without additional training and often lack complementary multimodal data. Here, we introduce Threads, a slide-level foundation model capable of generating universal representations of whole-slide images of any size. Threads was pre-trained using a multimodal learning approach on a diverse cohort of 47,171 hematoxylin and eosin (H&E)-stained tissue sections, paired with corresponding genomic and transcriptomic profiles - the largest such paired dataset to be used for foundation model development to date. This unique training paradigm enables Threads to capture the tissue's underlying molecular composition, yielding powerful representations applicable to a wide array of downstream tasks. In extensive benchmarking across 54 oncology tasks, including clinical subtyping, grading, mutation prediction, immunohistochemistry status determination, treatment response prediction, and survival prediction, Threads outperformed all baselines while demonstrating remarkable generalizability and label efficiency. It is particularly well suited for predicting rare events, further emphasizing its clinical utility. We intend to make the model publicly available for the broader community.
