**7. Prevention of venous thromboembolism in cancer patients**

Using Khorana risk scoring model or Ay Cihan et al expanded scoring model, it is within the reach of the attending hematologist/oncologist to stratify his/her cancer patient into one of the VTE risk groups: very high, high, intermediate or low and consider the patient for thromboprophylaxis in a patient-focused approach.

It also well understood that prophylaxis with antithrombotic agents can be problematic in cancer patients because they are at increased risk for anticoagulant induced bleeding. However, prophylaxis has been shown to be beneficial in certain high-risk populations such as post-surgical or hospitalized cancer patients but data in the ambulatory settings are conflicting.
