Federated CT Foundation Models for Multi-Center Detection of Lymph Node Metastasis in Pancreatic Cancer

2025-12-23

Abstract excerpt

<title>Abstract</title> <p>Pancreatic ductal adenocarcinoma (PDAC) remains one of the most lethal malignancies, with prognosis strongly influenced by the presence of lymph node metastasis (LNM). However, preoperative LNM assessment from computed tomography (CT) is limited by low sensitivity, high inter-observer variability, and substantial heterogeneity across imaging protocols. This retrospective multi-center st...
