Background and objective Malignant tumors often combined with venous thrombosis and pulmonary embolism, especially in lung cancer. It has been proven that, the mechanisms and risk factors for lung cancer patients contracting pulmonary embolism are unclear. The aim of this study is to summarize the clinical data on 54 patients with lung cancer and concomitant pulmonary embolism, and to analyze the risk factors and prognosis of lung cancer with pulmonary thromboembolism (PTE). Methods From April 1999 to January 2010, the clinical presentation of lung cancer patients with PTE from the Jiangsu Cancer Hospital and the Jiangsu Gerontic Institute were evaluated in the present retrospective study. Univariate analysis was conducted to determine the possible associated variables. Conditional logistic regression analysis was applied to explore risk factors of pulmonary embolism. Patient survival was also compared with matched controls via a Log-rank test. Results A total of 54 lung cancer patients with PTE, matched with 162 lung cancer patients as controls, were included. In the univariate analysis, a P140 g/L, and 1.76 in patients with central venous catheters. A significant difference was observed among the groups that received chemotherapy, adenocarcinoma, stage III-IV disease and high henoglobin (P
