Early liver metastasis (Early-LiM) is the most significant prognostic factor in pancreatic ductal adenocarcinoma (PDAC) and is thought to originate from occult micrometastases present at the time of surgery. Reliable preoperative detection of such lesions remains an unmet clinical need. The EXELiM study aims to develop and validate a circulating exosomal microRNA (exo-miRNA)-based liquid biopsy assay to accurately identify PDAC patients at high risk of occult liver metastasis before surgery. By integrating machine learning with multi-institutional plasma exosome profiling, this study seeks to enable biology-driven patient stratification and guide treatment sequencing toward precision oncology.
