Alok Khorana, MD, of the Cleveland Clinic joins Blood & Cancer host David H. Henry, MD, of Pennsylvania Hospital, Philadelphia, to break down the latest recommendations from the American Society of Clinical Oncology on venous thromboembolism (VTE) prophylaxis in cancer patients.
Plus, in Clinical Correlation, Ilana Yurkiewicz, MD, of Stanford (Calif.) University, shares her answer to a frequent question from cancer patients: What should I eat?
What is the role of thromboprophylaxis in patients with cancer in the outpatient setting?
- Key change in ASCO recommendations: Thromboprophylaxis with apixaban, rivaroxaban, or low-molecular-weight heparin (LMWH) may be offered to select high-risk outpatients with cancer.
- Prophylactic anticoagulation should not be given to every patient with malignancy.
- Khorana score predicts the venous thromboembolism in patients with malignancy.
- Influenced by type of malignancy, hemoglobin, platelet count, leukocyte count, and BMI.
- High risk = Khorana score of 2 or higher may be offered prophylaxis.
- Patients with pancreatic cancer and gastric cancer are particularly coagulopathic.
- Does the presence of a CNS lesion(s) preclude anticoagulation for a DVT/PE?
- All CNS lesions have a risk of hemorrhage.
- A CNS lesion hemorrhage is not significantly greater when anticoagulated
- Among high-risk cancer patients who undergo surgery, is there a role for postoperative prophylaxis with LMWH?
- Data show a persistent risk of VTE up to 4 weeks following abdominal/pelvic surgery.
