This study aimed to determine the incidence of VTE in ovarian cancer patients receiving NACT, identify risk factors for VTE, and assess the impact of VTE on treatment trajectory and overall survival. The results showed a VTE incidence of 13.3% and its association with decreased overall survival.
Objective: To determine the incidence of venous thromboembolism (VTE) in patients with ovarian cancer receiving neoadjuvant chemotherapy (NACT), identify risk factors for VTE, and assess the effect of VTE on treatment trajectory and overall survival. Methods: This isa retrospective cohort study of patients diagnosed with ovarian, fallopian tube, or primary peritoneal cancer treated with NACT between 2013 to 2016 in Alberta, Canada. The primary outcome was incidence of VTE during NACT. Secondary outcomes were risk factors for VTE and overall survival. Data related to patient demographics, cancer treatment, and incidence of VTE were collected. Statistical analyses included Kaplan-Meier estimates and univariate and multivariate Cox regression analysis. Results: A total of 284 patients were included in this study. Average age at diagnosis was 63.8 years. The incidence of VTE during NACT was 13.3%. Patients with VTE were less likely to undergo interval debulking surgery (58.3%) than patients without VTE (78.6%). Kaplan-Meier estimates demonstrated a decrease in overall survival in patients who had VTE during NACT (15.0 mo; 95% CI 14.5-16.5) compared with patients who did not (26.8 mo; 95% CI 22.8-30.9) (P < 0.0001). Multivariate analysis identified albumin <35 g/L, BMI >30 kg/m(2), and non-serous histology as risk factors for VTE. Conclusion: The risk of VTE in this cohort was 13.3%, which was associated with decreased overall survival. These findings suggest that thromboprophylaxis may have a role in this patient population.
