Background/Aim: The aim of this study was to elucidate the clinical impact of coagulation disorders on outcomes after curative resection of pancreatic ductal adenocarcinoma. Patients and Methods: Preoperative coagulation activity in 135 patients, who had undergone curative resections for pancreatic ductal adenocarcinoma was retrospectively evaluated and the impact on survival outcomes analyzed. Results: A prolonged prothrombin time-international normalized ratio (PT-INR) (≥1.1) was detected in 23/135 patients (17%). Univariate analysis that showed prolonged PT-INR was associated with worse relapse-free (hazard ratio=1.79, p=0.044) and overall (hazard ratio=2.18, p=0.004) survival. Multivariate analyses showed prolonged PT-INR, large tumor (>30 mm), and lymph node metastasis were independent predictors of poor overall survival. Conclusion: Prolonged PT-INR may be a predictor of poor prognosis in patients with pancreatic ductal adenocarcinoma who have undergone curative resection. Coagulation disorders may be a therapeutic target for improving outcomes of pancreatic ductal adenocarcinoma. [ABSTRACT FROM AUTHOR]
