Anticoagulants and Thrombotic Disorders
Conditions
Brief summary
Direct oral anticoagulants (DOACs) are now recommended as a first-line option in cancer patients with venous thromboembolism or atrial fibrillation. However, current international clinical practice guidelines and product inserts suggest caution and/or avoidance in using DOACs in case of potential potential drug-drug interactions (DDI), including DDI with anticancer therapies. Indeed, potential important DDIs can affect the efficacy and safety of DOACs and/or anticancer therapies and/or other interfering medications in these patients. Data about the pharmacokinetics (PK) of DOACs in cancer patients are scarce. By using a PK approach, this study aims : * to describe the PK profile of rivaroxaban and apixaban in adult cancer patients with venous thromboembolism or atrial fibrillation from a real-world setting * to identify factors (age, weight, renal function, co-morbidities, etc) influencing the PK profile of rivaroxaban and apixaban in adult cancer with venous thromboembolism or atrial fibrillation from a real-world setting.
