Incidence et impact de la maladie thrombo-embolique sur la prise en charge du cancer de l’ovaire
Ovarian cancer is a risk factor for venous thromboembolism (VTE), which worsens overall survival. The main objective of our study was to calculate the incidence of VTE in our population. We analyzed VTE impact on diagnosis and management of ovarian cancer. We conducted a retrospective, monocentric study in ovarian, fallopian tube and primary peritoneal cancer patients, divided into 2 groups (« Presence of VTE » and « Absence of VTE »). A univariate and multivariate analysis of factors associated with VTE was performed, and we compared delays of management in both groups. Among 157 patients included in the study, 22.9% presented a VTE, and 52.8% were asymptomatic. The VTE was diagnosed prior to any treatment in 61.1% of patients and revealed the ovarian cancer in 27.8% of cases. In multivariate analysis, tumor size (OR=1.1, 95% CI: 1-2.21, P=0.012), malnutrition (OR=3.79, 95% CI: 1.16-12,4, P=0.028) and Ddimer level above 1.5μg/mL (OR=13.8, 95% CI 1.2-152.8, P=0.02) were significantly associated with VTE. No significant difference was found between the two groups in diagnostic or therapeutic strategy, as well as in delays of management. We report a high incidence of VTE in ovarian cancer, including a lot of asymptomatic events. An early diagnosis with clinical examination and Ddimer level could improve its management and its prognosis.
