Core Tip
Core Tip: This study developed a predictive model for pathological grading of portosystemic venous invasion depth in borderline resectable pancreatic cancer using routine preoperative indicators: Serum carbohydrate antigen 19-9, computed tomography circumferential involvement angle, and luminal compromise. The model achieved high accuracy (C-index 0.928) in stratifying venous invasion depth into adventitial, muscularis propria, or intimal invasion, which significantly affected prognosis (e.g., intimal invasion showed worst median overall survival of 9 months). This innovative tool enables preoperative risk quantification, guiding personalized therapy decisions such as neoadjuvant intensification or surgical planning, and addresses a critical unmet need in precision oncology for borderline resectable pancreatic cancer.
