Establishment of a Patient-based Cohort : Cancer-related Venous Thromboembolic Disease.
Venous thromboembolic disease (VTE) is a common (1/1000), potentially serious disease (10% mortality when the clinical presentation is that of pulmonary embolism (PE)). In cancer patients, the risk of developing VTE is high and constitutes a negative prognostic factor for cancer; the risk of bleeding is also increased. The study of VTE in the context of cancer is a major challenge, given the frequency of the association, the heterogeneity of the situations, the risk factors involved and the therapeutic issues in both curative and primary prevention; in this field, many uncertainties remain, justifying a study focused on the association of VTE and cancer.
• Patients aged 18 years and more.
• Patients with active cancer or requiring cancer treatment at the time of their VTE episode
• Patients with documented VTE less than 2 years old
• Patients affiliated to the social security system
• Patient who has signed a written informed consent
