Low-molecular-weight heparin and direct oral anticoagulants are effective for cancer-associated venous thromboembolism, with switching to LMWH recommended for recurrent events.
This review provides a practical guide and treatment algorithm for managing recurrent venous thromboembolism in cancer patients, addressing a gap in current major guidelines.
Cancer patients have an increased risk of venous thromboembolism (VTE), and VTE is the second most common cause of death among them. Anticoagulation plays a key role in the treatment of cancer-associated thrombosis (CAT). Low-molecular-weight heparin (LMWH) or direct oral anticoagulants (DOACs) are effective and generally safe options for cancer-associated VTE. However, those patients have a 10-20% risk of VTE recurrence in spite of using anticoagulants. The main reasons for recurrent VTE (rVTE) can be non-compliance, inadequate dosing of anticoagulants, thrombocytopenia and malignancy progression. Despite the publication of major guidelines regarding the management of CAT, the treatment of patients with rVTE is undefined. Treatment options for rVTE include bridging to LMWH in cases of oral anticoagulants use, LMWH dose escalation, and sometimes considering inserting a vena cava filter. This review paper summarizes the management of cancer-associated VTE, risk factors for rVTE and the treatment algorithm of rVTE.
Kozhukhov et al. (Tue,) conducted a review in Cancer-associated venous thromboembolism. Anticoagulation (LMWH, DOACs) was evaluated. Low-molecular-weight heparin and direct oral anticoagulants are effective for cancer-associated venous thromboembolism, with switching to LMWH recommended for recurrent events.
