A unified multi modal transformer framework for breast cancer recurrence prediction and survival analysis
The presented multi-modal Transformer framework significantly advances breast cancer recurrence prediction and survival analysis by integrating diverse data sources (clinical, genomic, demographic, lifestyle) into a single, unified deep learning architecture. This approach achieves superior accuracy, precision, recall, and F1-scores (99.12%, 98.75%, 99.08%, 98.91% respectively) compared to traditional models, and substantially improves C-index for survival prediction (average 0.906). Its interpretability, generalizability across five real-world datasets, and efficiency in training make it a powerful tool for personalized breast cancer treatment and early intervention.

Unified Multi-Modal Transformer Framework
This research introduces a novel deep learning system that integrates survival analysis and multi-class recurrence classification for breast cancer. Unlike previous fragmented approaches, it offers a holistic view of patient prognosis. The framework leverages a Transformer-based survival module for time-until-recurrence estimation and an attention-guided classification module for risk categorization (second primary cancer, low-risk, high-risk recurrence). This unified approach provides comprehensive risk stratification, crucial for personalized treatment post-therapy.

Transformer-based Survival Module
A core innovation is the Transformer-based survival module, which captures long-range, non-linear correlations in time-to-event data more effectively than traditional proportional hazards models. This is critical for accurate time-until-recurrence estimation and goes beyond simple linear relationships, offering a more nuanced understanding of patient outcomes. The use of multi-head self-attention on fused feature vectors enhances interpretability by modeling complex dependencies.

Attention-Guided Classification Module
The framework includes an attention-guided classification module designed to differentiate between critical recurrence risk categories: second primary, low-risk, and high-risk. This module not only classifies but also emphasizes key decision-making features, providing clinicians with actionable insights. This granular classification allows for more precise patient stratification and tailored intervention strategies based on specific recurrence types.
Multi-Modal Data Fusion with Autoencoders
To address the challenge of heterogeneous data, the model integrates clinical, molecular, demographic, and lifestyle data from multiple established sources (METABRIC, GSE2034, GSE2990, BCSC, Breast Cancer Coimbra dataset). Autoencoder-based dimensionality reduction is used to minimize noise and non-linear dimensionality, while cross-modal feature fusion creates a single, comprehensive representation. This ensures that the model can leverage all available patient information for robust prediction.
