To increase the success of thromboprophylaxis in cancer outpatients, we propose, first, to include validated methods for predicting the risk of VTE at the time of cancer diagnosis(2, 3). This strategy will facilitate to identify cancer patients at high-risk for VTE and then, optimize the risk-to benefit ratio with anticoagulation. Second, to assess safety and efficacy of new oral anticoagulants in cancer patients as they represent an attractive alternative for an extended use of thromboprophylaxis. As a choice, new oral agents can be administered in fixed doses, do not require laboratory monitoring, have minimal interaction with additional drugs and provide a pain free alternative in patients who require injections.
