Abstract

OBJECTIVE: To characterize risk factors and timing of venous thromboembolism in women with uterine serous carcinoma. METHODS: A retrospective cohort study was performed including all women diagnosed with uterine serous carcinoma from 1999 to 2016 at our institution. Clinico-pathologic data and information regarding timing of venous thromboembolism were abstracted from the medical record. Logistic regression and Cox proportional hazards modeling were used to examine the association between covariates and risk and timing of venous thromboembolism. RESULTS: Seventy of the 413 included patients (17%) developed venous thromboembolism, with a median time from presentation to venous thromboembolism of 7.2 months (interquartile range 1.0-24.8) and from surgery to venous thromboembolism of 13.2 months (interquartile range 3.5-33.6). Fifty-nine of the 70 patients (84%) who developed venous thromboembolism were diagnosed either before surgery or greater than 6 weeks postoperatively. Twenty-two of the 70 patients (31%) who developed clots were on chemotherapy at the time of diagnosis. Venous thromboembolism was highly associated with cancer stage and presence of hypertension (P,.01). Cox proportional hazards modeling revealed that only cancer stages III and IV (hazard ratio [HR] 3.20, 95% CI 1.54-6.64 and HR 8.68, 95% CI 4.50-16.73, respectively) and hypertensive or cardiovascular diseases (HR 2.29, 95% CI 1.08-4.85 and HR 1.82, 95% CI 1.05-3.13) were associated with time to venous thromboembolism. CONCLUSION: Patients with uterine serous carcinoma are at high risk of developing venous thromboembolism even many months after their cancer diagnosis. This study generates the hypothesis that venous thromboembolism prophylaxis may be beneficial in patients with uterine serous carcinoma during other time points along the continuum of disease rather than only in the postoperative period, especially for those with advanced cancer.
