Khorana scale (with modifications by the American Society of Clinical Oncology) for assessing the risk of venous thromboembolism in patients receiving chemotherapy in an ambulatory setting.
| Clinical Characteristics: | No. of Points: |
|---|---|
| Type of cancer: stomach, pancreas, primary brain tumors (very high risk) Lungs, lymphoma, reproductive organs, bladder, kidneys (high risk) |
2 1 |
| Platelet count prior to chemotherapy ≥350,000/µL | 1 |
| Leukocyte count prior to chemotherapy >11,000/µL | 1 |
| Concentration of hemoglobin prior to chemotherapy <10 g/dL and/or use of erythropoietin | 1 |
| BMI ≥ 35 kg/m2 | 1 |
Interpretation: 0 points—minimal risk, 1–2 points—medium risk, ≥3 points—high risk.
