Multimodal deep learning model integrating electronic medical records and CT images for gallbladder cancer diagnosis: a retrospective multicenter study in China
This study proposes GBC-DiagNet, a multimodal deep learning model integrating electronic medical records (EMR) and CT images for gallbladder cancer (GBC) diagnosis. It achieved 93.3% accuracy, 96.2% sensitivity, 91.2% specificity, and 0.9706 AUC, significantly outperforming unimodal and state-of-the-art deep learning models. The model enhances early, non-invasive GBC diagnosis, addressing challenges in an aggressive cancer with poor prognosis.
Executive Impact
GBC-DiagNet's multimodal approach significantly elevates diagnostic precision for gallbladder cancer, addressing a critical need for early detection in a highly aggressive disease. This breakthrough translates directly into improved patient outcomes and substantial operational efficiencies for healthcare providers.

The Challenge of Gallbladder Cancer Diagnosis
Gallbladder cancer (GBC) is a highly aggressive gastrointestinal malignancy with a global 5-year survival rate of less than 5%. Its early diagnosis is critically challenging due to a lack of specific clinical symptoms and high tumor heterogeneity, often leading to delayed diagnosis and impractical surgical intervention. Existing diagnostic models often rely on unimodal data, limiting their ability to capture the full spectrum of diagnostic information.
GBC-DiagNet: A Multimodal Deep Learning Solution
The study proposes GBC-DiagNet, a novel two-stage multimodal deep learning model. The first stage uses a position-constrained 3D Attention U-Net with combined sampling for coarse segmentation of the gallbladder region from contrast-enhanced CT images. The second stage employs an adaptive feature fusion strategy, optimizing the weighted integration of handcrafted radiomic, deep radiomic, and laboratory examination features for precise GBC detection. This multimodal approach aims to leverage complementary data sources to overcome limitations of unimodal methods.

Clinical Integration Strategy
GBC-DiagNet is designed as a second-opinion auxiliary tool. It provides confidence scores (0-100%) and segmentation quality (Dice score). For high-confidence cases (≥85% with Dice ≥0.7), it supports clinician decisions. Low-confidence cases (<60% or Dice <0.6) are flagged for caution. Discordance triggers a reconciliation protocol: review interpretability outputs, optional manual ROI adjustment, and multidisciplinary team consultation. All outputs are logged as 'AI auxiliary opinion' in EMR for traceability, with clinicians retaining ultimate diagnostic responsibility.
