Khorana Score (Cancer-Associated Thrombosis) Calculator

Khorana Score: Explanation and Clinical Context The Khorana Score is a validated risk assessment model for predicting cancer-associated thrombosis (CAT) in ambulatory patients with cancer. It assigns points based on five clinical variables: site of cancer, platelet count > 350 ×10^9/L, hemoglobin < 10 g/dL or use of erythropoiesis-stimulating agents, leukocyte count > 11 ×10^9/L, and BMI > 35 kg/m². Scores classify patients into low (0 points), intermediate (1–2 points), or high (>3 points) risk for venous thromboembolism.

This tool guides clinicians in considering prophylactic anticoagulation and close monitoring in high-risk patients.
