NCT07803770

Brief Summary

The EUS-AI-R study is an observational, single-center, two-phase (retrospective-prospective) study designed to develop and validate artificial intelligence (AI) models for predicting chemotherapy response and oncological outcomes in patients with pancreatic ductal adenocarcinoma (PDAC). Patients who underwent endoscopic ultrasound (EUS) with tissue acquisition (EUS-FNA/FNB) for suspected pancreatic lesions at IRCCS San Raffaele Hospital between January 1st, 2019 and January 2026 will be retrospectively included. All patients have a histologically confirmed diagnosis of PDAC and a minimum follow-up of six months. These data derive from an IRB-approved institutional study (BIOPANCREAS; NCT06552078). Retrospective multimodal data, including EUS imaging (B-mode, elastography, contrast-enhanced EUS), clinical and laboratory variables, CT/MRI imaging, digital pathology, and molecular data when available, will be used to develop and internally validate multiple AI models. In the prospective phase, the best-performing AI model will be applied to an independent cohort of patients undergoing EUS at the same institution to evaluate feasibility, calibration, and real-world performance. No additional procedures beyond standard clinical practice will be performed.

Outcome Measures

Primary Outcomes (1)

  • Development of an AI algorithm predicting chemotherapy response in patients with pancreatic cancer

    Development of AI models to predict chemotherapy response in patients with PDAC by evaluating the predictive performance of: 1. An EUS-based AI model (pre-treatment EUS images/videos) 2. A clinical/exposome-based AI model (pre-treatment clinical and laboratory variables) 3. A radiology-based AI model (pre-treatment CT/MRI radiomics) 4. A digital pathology-based AI model (histopathology slides) 5. A multimodal AI model combining all available data sources (EUS + clinical/exposome + CT/MRI radiomics + digital pathology ± molecular data when available) Chemotherapy response will be defined according to radiological response criteria (RECIST) and biochemical response assessed by CA19-9 levels. Model performance will be assessed using AUC-ROC, sensitivity, and specificity.

    6 months

Secondary Outcomes (3)

  • Recurrence-Free Survival (RFS) Rate based on AI Models

    From the date of histological diagnosis of pancreatic cancer until the date of first documented recurrence or death from any cause, whichever came first, assessed up to 6 months

  • Progression-Free Survival (PFS) Rate based on AI Models

    From the date of histological diagnosis of pancreatic cancer until the date of first documented disease progression or death from any cause, whichever came first, assessed up to 6 months

  • Overall Survival (OS) Rate based on AI Models

    From the date of histological diagnosis of pancreatic cancer until the date of death from any cause, assessed up to 6 months

Other Outcomes (3)

  • Diagnostic Accuracy and Discrimination (AUC-ROC)

    1 year

  • Diagnostic Accuracy (Sensitivity and Specificity) of AI Models

    1 year

  • Model Calibration, Stability, and Prospective Feasibility

    1 year
