    ObjectivesActivation of coagulation and fibrinolysis is frequently observed in patients with cancer, even with absence of thrombosis. Furthermore, plasma coagulation parameters were associated with tumor progression, metastasis, and prognosis. Few studies have investigated these associations in pancreatic cancer (PA). This study aimed to investigate the clinical and prognostic significance of various plasma coagulation tests in PA patients with absence of venous thromboembolism (VTE).Materials And MethodsA total of 139 PA patients with the absence of VTE were included in the analysis. Patients were followed up for at least 12 months until death. Pretreatment coagulation parameters including prothrombin time (PT), international normalized ratio (INR), activated partial thromboplastin time (APTT), fibrinogen (F), antithrombin-III (AT-III), protein C (PC), factor-VIII (F-VIII), and D-dimer (DD) were evaluated. A total of 40 age-matched and sex-matched healthy individuals without coagulation disorder were enrolled as the control group.ResultsPatients were inclined to have higher levels of PT, INR, APTT, F, F-VIII, and DD and lower levels of AT-III and PC than the control group (P<0.01 for all, except P=0.022 for INR and P=0.015 for AT-III). Patients with advanced tumor stages were likely to have higher median DD levels and lower AT-III levels than the control group (P=0.005 and P<0.001, respectively). DD levels were higher in patients with advanced pathology grade (P<0.001). Plasma DD levels (hazards ratio=1.71; 95% confidence interval, 1.07-2.73; P=0.025) were identified as the significantly independent prognostic predictors.ConclusionsPA patients are susceptible to activation of hemostasis system. Pretreatment plasma DD level was a potential predictor of prognosis in PA patients without VTE.
