Predictive model for chemotherapy-associated venous thromboembolism

Patient characteristicsRisk score
Site of cancer
 Very high risk (stomach, pancreas)2
 High risk (lung, lymphoma, gynaecologic, bladder, testicular)1
Prechemotherapy platelet count ≥350000 per mm31
Haemoglobin level <10 g·dL−1 or use of red cell growth factors1
Prechemotherapy leukocyte count >11000 per mm31
Body mass index ≥35 kg·m−21

A risk score ≥3 is a high-risk score, 1–2 is an intermediate score, and 0 is a low-risk score.
