Greetings, math whizzes and data nerds! Ever scratched your head over the Khorana Risk Score for cancer-associated thrombosis? Well, your brain-boggling days are over. Strap in for a wild ride through the numerical jungle with this formula:
Khorana_Score = (BMI >= 35)*2 + (Platelets >= 350)*1 + (Hemoglobin < 10 or use of erythropoiesis-stimulating agents)*1 + (Leukocytes > 11)*1 + Cancer site-specific score
Khorana Score Categories
Category |
Score Range |
Interpretation |
Low Risk |
0 |
Thrombosis risk is minimal, no need for alarm bells |
Intermediate Risk |
1-2 |
Thrombosis risk is moderate, keep an eye out |
High Risk |
>=3 |
Thrombosis risk is high, caution is advised |
Examples

Result |
John Doe, 220 lbs, 6′ tall, platelet count of 400, hemoglobin of 9, leukocytes of 12, stomach cancer |
2 (BMI) + 1 (platelets) + 1 (hemoglobin) + 1 (leukocytes) + 2 (cancer type) = 7 |

FAQs
- What is the Khorana Score?: The Khorana Score is a tool used to determine the risk of cancer-associated thrombosis.
- How is the Khorana Score calculated?: The score is calculated using a combination of factors including BMI, platelet count, hemoglobin level, leukocyte count, and cancer type.
- What does a low Khorana Score mean?: A low score indicates a minimal risk of thrombosis.
- What does a high Khorana Score mean?: A high score indicates a high risk of thrombosis and caution is advised.
- Can the Khorana Score be used to diagnose cancer?: No, the Khorana Score is only used to assess the risk of thrombosis in patients with cancer.
- Are there other methods to calculate the risk of thrombosis?: Yes, other methods such as the Vienna Score and Ottawa Score can also be used.
- How accurate is the Khorana Score?: The accuracy of the Khorana Score can vary depending on the specific risk factors of the patient.
- Can the Khorana Score change over time?: Yes, the score can change as the patient’s condition and risk factors change.
- Is the Khorana Score used worldwide?: Yes, the Khorana Score is widely used in many countries around the world.
- Can I calculate my own Khorana Score?: Yes, but it’s recommended to consult a healthcare professional for an accurate assessment.
