Abstract excerpt
OBJECTIVE: Accurate detection of PIK3CA mutations is essential for guiding PI3K-targeted therapies in breast cancer, yet sequencing is not universally accessible, and single-modality prediction models have limited performance. This study developed a multimodal deep learning framework integrating whole-slide imaging (WSI) and structured clinical data to improve mutation prediction. METHODS: A total of 1,047...
