- Development of PRIME, a parsimonious risk stratification model for pancreatic ductal adenocarcinoma (PDAC) using EHR data.
- Model trained on 4.8M+ US patients, validated on 5.6M+ across 31 health systems and 498K UK Biobank participants.
- Retained 19 predictors including pancreatitis history, type 2 diabetes, smoking, and non-type-O blood.
- Achieved 36-month AUC of 0.75 (US) and 0.71 (UK) with good calibration.
- Top 1% risk patients had 7.63x higher PDAC risk vs average (95% CI 6.85-8.49).
- Proposes EHR-guided case-finding integration with blood-based detection assays.
