Abstract:
218 Background: Thromboembolism (TE) is common in cancer patients, and pancreatic cancer is reported to be highly associated with TE. The aim of this analysis is to clarify risk factors for TE and its clinical impact in pancreatic cancer patients. Methods: Data on consecutive pancreatic cancer patients receiving systemic chemotherapy between August 1999 and July 2015 were retrospectively studied. The diagnosis of TE was made on CT scan either performed for suspicious symptoms of TE or for evaluation of chemotherapy response, and TE was classified into two groups: arterial events including coronary artery disease (CAD), cerebrovascular disease and other artery thrombosis, and venous events including deep vein thrombosis/pulmonary embolism (DVT/PE), portal vein thrombosis (PVT) and IVC thrombosis. Overall survival and time to TE (TTE) were calculated by Kaplan-Meier analysis. Risk factors for TE development were analyzed using a Cox proportional hazards model. To evaluate the impact of TE on survival, multivariate analyses were performed using a time-dependent covariate multiple Cox model. Results: A total of 475 patients (195 female, a median age of 67 years) were analyzed. TE was identified in 57 patients (12%). Venous TE were 45 (79%) including DVT/PE 24(42%), IVC thrombosis 2 (4%), PVT 19 (33%). Arterial TE were 12 (21%) including cerebrovascular infarction 9 (16%), CAD 2 (4%) respectively. The median TTE was 169 days (95% CI, 75-203). Liver metastasis was the only significant risk factor for TE in the multivariate analysis (OR 2.01, 95%CI 1.12-3.47, P = 0.012). The median survival from TE development was 57 days (95% CI, 37-65) and TE was significantly associated with poor prognosis (HR 3.31, 95%CI 2.72-5.27, P 〈 0.01) in the time-dependent covariate analysis. Conclusions: TE was not uncommon in pancreatic cancer patients receiving chemotherapy and was associated with poor prognosis. Whether the prophylaxis for TE can improve survival should be further investigated, especially in high risk patients such as patients with liver metastasis.
