Addressing the Bottlenecks in Digital Pathology
Whole Slide Images (WSIs) are foundational for pathological diagnosis, yet their immense size and the prohibitive cost of detailed, pixel-level annotations create significant hurdles for automated analysis. Current Multiple Instance Learning (MIL) approaches offer a partial solution for weak supervision but often suffer from insufficient adaptability with single deep features and limited model robustness, making accurate diagnosis in real-world clinical settings challenging.
Our research introduces a robust framework designed to overcome these limitations, integrating advanced deep learning techniques with a sophisticated soft voting strategy. This ensures a comprehensive analysis of WSIs, delivering high accuracy and reliability crucial for breast cancer detection and classification.

The weighted average soft voting strategy significantly surpasses single deep models and basic MIL methods, demonstrating its superior capability in accurate WSI-based disease prediction.
Transforming Breast Cancer Diagnosis and Beyond
Enhancing Clinical Pathways and Future AI Integration
Our framework offers significant clinical practical value for breast cancer pathological diagnosis. It acts as a "second pair of eyes" for pathologists, dynamically highlighting key malignant cell clusters and reducing average diagnosis time from 15-30 minutes to a more efficient workflow. For resource-constrained regions, it enables automatic classification of WSIs into "high-risk" (malignant) and "low-risk" (benign) categories, optimizing limited pathological resources and ensuring timely diagnosis.
A core advantage is its independence from pixel-level or patch-level fine annotations, dramatically reducing clinical data annotation costs by over 90%. Its modular design also facilitates easy integration with existing pathological workstations, offering a reusable technical paradigm for AI-assisted diagnosis.
Future work will focus on integrating multi-modal data, including other pathological imaging (CT/MRI), patient clinical data (age, tumor stage, treatment history), and genetic data (somatic mutations, gene expression). We will adopt targeted multi-modal fusion technologies, such as cross-modal attention mechanisms and graph neural networks, to model complex associations between different data types. This will not only boost diagnostic accuracy but also reveal hidden correlations, driving new scientific insights and promoting the comprehensive integration of AI with clinical diagnosis and precision oncology.
