Abstract
PURPOSE
To identify potential risk factors for the development of venous thromboembolic events in testicular cancer patients receiving platinum-based chemotherapy.
METHODS
We performed a retrospective analysis including 255 patients with testicular germ cell tumors who received platinum-based chemotherapy from 2003 to 2018 as a multi-center observational cohort study. Patient and tumor characteristics of patients with and without a thromboembolic event were analyzed.
RESULTS
49 (19%) patients experienced a venous thromboembolic event, with the majority representing pulmonary embolism and deep venous thrombosis (47%). There were no significant differences regarding the development of a venous thromboembolic event between first- and second-line regimes. Multivariate analysis showed an increased risk for a venous thromboembolic event in patients with clinical stage ≥ IIC disease (OR 2.259 [95% CI 1.105-4.618], p = 0.026), elevated serum LDH (OR 2.162 [95% CI 1.018-4.593], p = 0.045), febrile neutropenia (OR 2.973 [95% CI 1.363-6.487], p = 0.006) and central venous access (OR 3.465 [95% CI 1.068-11.243], p = 0.039). Patients suffering from a venous thromboembolic event revealed a significantly reduced overall survival (p = 0.033) during a median follow-up of 8 months [IQR 2-18].
CONCLUSIONS
19% of all patients treated by platinum-based chemotherapy due to testicular cancer suffered from a venous thromboembolic event, associated with reduced overall survival. As a result, monitoring of cancer patients at risk as well as the improvement of patients' awareness of a thromboembolic event should thus be the main goal of their treating physicians.
