Development and validation of a multimodal AI-agent system for prognosis analysis of bladder urothelial carcinoma
This study introduces a novel AI agent for bladder urothelial carcinoma (BUC) prognosis, integrating diverse clinical data for enhanced accuracy and interpretability. Our system pioneers a multimodal approach, combining textual, radiographic, and pathological insights to deliver precise, personalized risk stratification. It represents a significant leap forward in oncology, moving beyond traditional methods to offer a more nuanced understanding of patient outcomes and treatment responsiveness.

Key Insight: Precise Tumor Segmentation
Achieving high precision in tumor segmentation is foundational for accurate prognostic analysis. Our interactive Swin-UNETR network demonstrated an average Dice Similarity Coefficient (DSC) of 83.01% (ranging 80.03%–84.32%), significantly outperforming traditional methods. This ensures that the AI agent accurately identifies and delineates bladder urothelial carcinoma (BUC) lesions, providing a reliable basis for subsequent feature extraction from radiographic images. The interactive nature allows for expert-guided refinement, boosting both accuracy and clinical confidence.
Key Insight: Multimodal Data Processing Pipeline
The AI-agent system processes data through a sophisticated multi-stage pipeline. It begins with Large Language Models (LLMs) structuring unstructured pathology reports. Simultaneously, an interactive Swin-UNETR network performs precise CT image segmentation. Features are then extracted from CT scans (CTVisionNet) and whole slide images (BUCSegNet, CONCH) to capture both macroscopic and microscopic pathological insights. Finally, the MATCH-Net framework integrates these diverse multimodal features using a multi-head attention mechanism to generate a comprehensive and interpretable prognostic score.
Key Insight: Superior Prognostic Performance
MATCH-Net significantly outperforms single-modality models (CTVisionNet, MacroVisionNet) and other state-of-the-art approaches in prognostic prediction. With a C-index of 0.854 (CQMFH-T cohort), it demonstrates superior accuracy and robustness due to its multimodal fusion capabilities. The framework's ability to integrate textual, radiographic, macroscopic, and microscopic features provides a more comprehensive understanding of tumor biology, leading to better-informed clinical decisions and identification of patients who would benefit most from adjuvant chemotherapy.
Key Insight: Identifying ACT Responders
Our AI-agent system has demonstrated a crucial clinical utility: identifying high-risk bladder urothelial carcinoma (BUC) patients who derive significant survival benefits from adjuvant chemotherapy (ACT). For patients categorized as high-risk by MATCH-Net, those who received ACT showed improved overall survival with Hazard Ratios (HRs) ranging from 0.12 to 0.46. This capability supports personalized treatment strategies, ensuring that intensive therapies are directed towards patients most likely to respond, thereby optimizing outcomes and minimizing unnecessary interventions.

Precision in Action: Identifying High-Risk BUC Patients for Adjuvant Chemotherapy
A high-risk patient, identified by MATCH-Net, showed a significant survival benefit after receiving adjuvant chemotherapy (ACT). This patient, initially classified by conventional staging as intermediate risk, had specific microscopic features (e.g., high Tumor Muscle Infiltration Fraction) highlighted by our AI-agent as critical prognostic indicators. The multimodal fusion allowed for a more accurate risk assessment, demonstrating the system's ability to identify those who truly benefit from intensified treatment, leading to a hazard ratio improvement of up to 0.12 for ACT responders in the high-risk group.
