Abstract 3844: Venous thromboembolism in patients with pancreatic cancer

Abstract

Abstract Background: Venous thromboembolism (VTE) is a critical complication of malignant disease. Pancreatic cancer is one of the cancers most commonly associated VTE. In general, the VTE incidence rate of Asians is lower than that of Caucasians. In 2007, a Korean study reported that only four cases of VTE (5.3%) occurred in Seventy five patients with advanced pancreatic adenocarcinoma. We evaluated VTE incidence in pancreatic cancer and characteristics of pancreatic cancer patients with VTE. Method: We retrospectively reviewed the medical records of patients with histopathologically proven pancreatic cancer from January 2006 to December 2012 at Soonchunhyang university hospital. We detected VTE through CT (chest CT, pulmonary embolism CT) and low extremity ultrasoundgraphy. Results Five hundred and fourteen patients with pancreatic adenocarcinoma were enrolled. (M: F, 300:214, localized: locally advanced: metastatic=31:230:253, mean age: 66.7 years). Ninety six of 514 patients (18.6%, symptomatic: aymptomatic=38:58, PE: DVT: PE+DVT: visceral thrombosis=20:19:19:38) were diagnosed as VTE. At the time of DVT diagnosis, cancer status of 50 patients cancer was progression, and that of 15 was stable. Thirty one patients were diagnosed with the pancreatic cancer and VTE, at the same time. They all had metastatic lesions. Fifty VTE patients were treated with antithrombotic therapy. Ninety three of 96 patients died, and three of them have probability that cause of death was VTE. The others died of pancreatic cancer progression. From pancreatic cancer diagnosis to VTE diagnosis, the period is 1.7month. (95%CI 1.1-2.3 month). Median overall survival (OS) was not significantly different between pancreatic cancer with VTE or without VTE. OS was significantly longer VTE patients after pancreatic cancer diagnosis than VTE patients with pancreatic cancer at the same time (10.73m vs. 1.7, p=0.00). Conclusion The incidence of VTE (18.6%) in Soonchunhyang university hospital with pancreatic cancer was not lower than that in western groups.
