There is paucity of data on venous thromboembolism (VTE) in patients receiving neoadjuvant chemotherapy (NACT) for advanced stage ovarian cancer. We explored the incidence and predictors of VTE in this patient population. We performed a retrospective review of women with primary ovarian, fallopian tube or peritoneal cancer who received NACT between January 2012 and October 2018 at Cooper University Hospital. Patients with history of VTE, heparin therapy or direct oral anticoagulant use prior to cancer diagnosis were excluded. The primary outcome was incidence of deep vein thrombosis (DVT) or pulmonary embolism (PE) after cancer diagnosis. We explored demographic and clinical variables associated with VTE. Of 90 patients included, 25 (28%) were diagnosed with VTE and 16 (64%) had PE. Eight patients were diagnosed after cancer diagnosis prior to the start of chemotherapy and 17 patients during NACT. Most patients had stage III disease and serous adenocarcinoma. There was a trend towards increased risk of VTE for Black patients (OR 3.22; CI 0.997–10.42; P = 0.051). Significantly fewer patients with VTE had debulking surgery (60% vs. 88%, P = 0.005). The risk of DVT increased by 8.7% per year of age (OR 1.087; 95% CI 1.01–1.17). Obesity, smoking status, medical comorbidities, disease stage, histology, invasive diagnostic surgery, and length of NACT were not associated with VTE. The incidence of VTE during neoadjuvant chemotherapy is high. Older age and Black race may increase the risk of VTE, and this morbid complication may adversely impact cancer treatment.
