Predictive model for chemotherapy-associated venous thromboembolism
| Patient characteristics | Risk score |
| Site of cancer | |
| Very high risk (stomach, pancreas) | 2 |
| High risk (lung, lymphoma, gynaecologic, bladder, testicular) | 1 |
| Prechemotherapy platelet count ≥350 000 per mm3 | 1 |
| Haemoglobin level <10 g·dL−1 or use of red cell growth factors | 1 |
| Prechemotherapy leukocyte count >11 000 per mm3 | 1 |
| Body mass index ≥35 kg·m−2 | 1 |
A risk score ≥3 is a high-risk score, 1–2 is an intermediate score, and 0 is a low-risk score.
