Multimodal analysis of whole slide images in colorectal cancer
This systematic review critically appraises multimodal digital pathology techniques applied in Colorectal Cancer (CRC), their performance, and contrasts them with foundation models. It highlights enhanced diagnostic accuracy and survival prediction through integrated modalities like digital pathology, radiology, clinical information, and omics data, while also addressing challenges in data heterogeneity and validation.
Executive Impact
Multimodal AI in CRC significantly improves diagnostic accuracy and prognostic predictions by integrating diverse data sources. This leads to more personalized treatment planning and better patient outcomes. Overcoming data heterogeneity and ensuring robust external validation are key to clinical adoption, promising a transformative shift in cancer diagnostics and treatment.

Multimodal Integration
Multimodal models enhance colorectal cancer (CRC) care by integrating diverse data sources. Whole Slide Images (WSIs) provide detailed visual information on architecture and cellular morphology, while clinical data (demographics, medical history), genomics (molecular insights), and radiological scans (macroscopic information) offer complementary context. This comprehensive integration captures the multifaceted nature of CRC, improving diagnostic accuracy, prognostic predictions, and personalized treatment decisions beyond what any single modality can achieve.
Fusion Techniques
Various fusion techniques are employed to integrate multimodal data. Early fusion combines raw data before feature extraction, while intermediate fusion happens during model processing after initial feature extraction. Late fusion involves independent processing of each modality, with their outcomes fused at the decision-making stage. Common methods include Multimodal Compact Bilinear (MCB) pooling and attention-based fusion, which dynamically weigh modalities based on relevance to the predictive task. Shared latent spaces and contrastive alignment are used for joint learning of modality-invariant representations.
Performance Gains
Multimodal approaches consistently outperform unimodal models in CRC prediction. Studies show significant improvements in diagnostic accuracy, survival prediction, biomarker identification (e.g., TMB, MSI, KRAS mutations), and pathological staging. For instance, combining WSIs with clinical data can increase AUC by 4% for survival prediction, while integrated histopathology and Ki67 data improve pathological staging AUC to 0.93. Foundation models show promise for further enhancing generalizability and performance across diverse tasks.
Challenges & Limitations
Despite significant advancements, multimodal AI in CRC faces several challenges. Data heterogeneity, including variations in collection methods and temporal alignment across institutions, can impact model generalizability. Constructing large, comprehensive multimodal datasets is resource-intensive. Missing data, model interpretability, and determining optimal modality weighting remain significant hurdles. Furthermore, the limited external validation and lack of widespread digital pathology infrastructure hinder real-world clinical utility and broad adoption of these advanced models.

Case Study: Biomarker Prediction in CRC with Multimodal AI
A study demonstrated the predictive value of multimodal fusion for microsatellite instability (MSI) in CRC. By integrating Whole Slide Images (WSI) and molecular data, researchers achieved a 14% improvement in MSI prediction accuracy compared to unimodal models. This enabled more precise identification of patients who would benefit from specific immunotherapies, moving towards personalized medicine.

Implementation Roadmap
Navigate your AI transformation with a clear, phase-by-phase strategic plan.
Phase 1: Data Assessment & Infrastructure Audit
Conduct a comprehensive audit of existing digital pathology, radiology, clinical, and omics data. Evaluate current IT infrastructure for AI model deployment and scalability, ensuring compliance with data privacy regulations (e.g., GDPR, HIPAA). Identify data gaps and establish a data governance framework for multimodal data integration.
Phase 2: Pilot Program & Model Development
Select a specific CRC diagnostic or prognostic task for a pilot program. Develop or adapt multimodal AI models (e.g., integrating WSIs with clinical data) using a representative, de-identified dataset. Focus on robust feature extraction and fusion techniques, and establish baseline performance metrics against current unimodal approaches.
Phase 3: Validation, Interpretability & Clinical Integration
Rigorously validate the pilot model's performance on independent internal and external datasets. Address model interpretability by quantifying modality contributions and biases. Develop a strategy for seamless integration into existing clinical workflows, training pathologists and clinicians on AI tools, and establishing feedback loops for continuous improvement.
Phase 4: Scaled Deployment & Continuous Monitoring
Expand multimodal AI solutions to broader CRC applications across the enterprise. Implement continuous monitoring of model performance, clinical impact, and user adoption. Establish a system for regular model retraining with new data, ensuring long-term reliability, generalizability, and ethical use in diverse clinical scenarios.
