Interpretable deep learning model and nomogram for predicting pathological grading of PNETs based on endoscopic ultrasound
This study developed and validated a novel interpretable DL model and nomogram using EUS images and machine learning, which holds promise for enhancing the clinical application of EUS in identifying PNETs' pathological grading.
Executive Impact Summary
The novel interpretable deep learning (DL) model and nomogram leverages endoscopic ultrasound (EUS) images for predicting pathological grading of pancreatic neuroendocrine tumors (PNETs). It integrates deep transfer learning with a pre-trained ResNet18 model and clinical features, achieving high predictive accuracy and interpretability, as visualized by SHAP.
Core Business Value
Enables non-invasive, accurate preoperative pathological grading of PNETs, which is critical for guiding treatment strategies and improving patient outcomes. Reduces reliance on subjective interpretation of EUS images and enhances the precision of diagnostic and prognostic assessments.

Clinical Impact & Interpretability: A Patient Scenario
Scenario: A 55-year-old patient presents with a pancreatic lesion detected via EUS. The DL model and nomogram predict a high risk (0.804) for G2/3 PNETs.
Outcome: Based on this prediction, proactive clinical interventions, including surgical planning, were initiated earlier. SHAP analysis revealed that specific DL features related to lesion texture and internal homogeneity were strong indicators for this high-grade prediction, providing clinicians with actionable, explainable insights beyond traditional visual assessment. This interpretable approach enhanced physician confidence in the AI's recommendation and led to a more timely and targeted treatment strategy.
