Prevention, anticoagulation and the bleeding balance
Venous thromboembolism is a common complication of cancer and its treatment. Risk varies with cancer type, stage, surgery, hospitalisation and systemic therapy. Anticoagulation is used for treatment and sometimes prophylaxis, balanced against bleeding risk and drug interactions. Myeloma and lymphoma regimens have specific clot risks.

A structured assessment includes cancer type and stage, recent surgery, hospitalisation, immobility, prior VTE, chemotherapy and central venous access. Thromboprophylaxis is considered for hospitalised and selected ambulatory patients. In myeloma, immunomodulatory drugs require risk-based prophylaxis.
Low-molecular-weight heparin, direct oral anticoagulants and warfarin are selected according to cancer type, renal function, thrombocytopenia, drug interactions and patient preference. Duration is usually at least three to six months and may be extended in active cancer. Bleeding risk and platelet count are reviewed regularly.
