Not addressed in cancer patients | LMWH is recommended for the initial 5 to 10 days of treatment for DVT and PE in patients with a CrCI>30 mL/min. |
Long-term treatment | - LMWH is recommended for first 6 months as monotherapy without warfarin in patients with proximal DVT or PE and metastatic or advanced cancer. - Warfarin 2.5–5 mg every day initially with dynamic dosing strategy based on INR value targeted at 2–3. |
-LMWH preferred to VKA - In patients not treated with LMWH, VKA therapy is preferred to dabigatran or rivaroxaban - Patients receiving extended therapy should continue with the same agent used for the first 3 months of treatment |
- LMWH is recommended for long-term therapy for DVT and PE - VKAs (target INR, 2–3) are acceptable for long-term therapy if LMWH is not available. - Use of novel oral anticoagulants is not recommended - Patients with cancer should be periodically assessed for VTE risk |
Duration of therapy | Minimum 3 months. Indefinite anticoagulant if active cancer or persistent risk factors. |
Extended therapy is preferred to 3 months of treatment | At least 6 months duration. Extended anticoagulation with LMWH or VKA beyond 6 months for patients with: - metastatic disease -receiving chemotherapy -recurrent thrombosis |
