title: [Analysis about the high risk factors and prognosis of gynecologic cancer with deep venous thrombosis].
abstract: OBJECTIVE
  To discuss the risk factors and prognosis of gynecologic cancer patients with deep venous thrombosis (DVT).
  
  
  METHODS
  Data from gynecologic cancer patients diagnosed by cytology or histopathology in Affiliated Tumor Hospital of Guangxi Medical University between Jan. 1994 and Sep. 2014 were collected, including 106 cases in the DVT group, according to 1:1 proportion by the computer random method to selecting patients without DVT as the control group. The follow-up deadline was March 31, 2015. The median follow-up time of DVT group was 27.0 months (range, 1 to 169 months), while the control group was 33.5 months (range, 1 to 125 months). Univariate analysis was performed by two independent sample t test or χ² test. Multivariate analysis was performed by logistic regression analysis. The Kaplan-Meier curve was used to estimate the survival analysis.
  
  
  RESULTS
  (1) The univariate analysis showed that body mass index (BMI), hypertension, diabetes, history of thrombosis, tumor stage, blood transfusion, stimulating factor, white blood cell (WBC), platelet (PLT), prothrombin time (PT) and fibrinogen (FIB) were statistically significant associated with DVT (P < 0.05). Multivariate analysis showed that tumor stage, stimulating factor, WBC, PT and FIB may be the independent risk factors of gynecologic cancer with DVT (P < 0.05). (2) The median survival time in DVT group was 66 months, while the control group was 102 months (χ² = 7.039, P = 0.008). The overall survival and progression-free survival in the DVT group were statistically significant lower than those in the control group (P < 0.05). The tumor stage, the scope of DVT (whether with pulmonary embolism) and the treatment of DVT were the effective factors influenced the prognosis of gynecologic oncology patients with DVT (P < 0.05). Cox regression model showed that tumor stage and the scope of DVT were the independent risk factors (P < 0.01).
  
  
  CONCLUSIONS
  Gynecologic cancer with DVT is the common effect of various risk factors. We should identify the risk factors for high-risk patients and take preventive measures actively to reduce the deep venous thromboembolism, then improve the survival of patients and their prognosis.
