Abstract

Patients with advanced endometrial cancer (EC) are at risk for venous thromboembolism (VTE), though risk by treatment phase remains unclear. This single-institution retrospective study evaluated 84 patients receiving neoadjuvant chemotherapy (NACT, n=34) or adjuvant chemotherapy (n=50) for stage III-IV EC. Overall VTE incidence was 27.4% (95% CI, 18.8-38.0%). Among patients receiving NACT, VTE occurred in 14.3% during NACT and in 16.7% during ongoing chemotherapy. Postoperative and adjuvant treatment rates were less than 10.0%. Khorana score was a poor predictor of VTE, with 52.0% of intermediate-risk patients developing VTE. These findings highlight the need for improved VTE risk-reduction strategies, including larger studies to evaluate optimization of risk stratification and VTE prophylaxis during systemic therapy for advanced EC.
