Scientific background

Cancer-associated venous thromboembolism (VTE) is the second largest common cause of death in cancer patients after the cancer itself. Cancer patients may have a four- to seven-fold increased risk of VTE compared with the general population. The risk varies considerably from patient to patient and is based on factors such as the malignancy itself, treatment and patient-associated features as shown in Table 1.1, 2

Table 1 Risk factors for cancer-associated VTE



Cancer-associated risk factors 
 Tumour site and size
 Tumour stage and grade
 Time interval after diagnosis (up to six months)
Treatment-associated risk factors  
 Chemo- and radiotherapy
 Hormonal therapy
 Indwelling intravenous catheters
 Antiangiogenic agents
Patient-associated risk factors  
 Life style-related risk factors, i.e. smoking, obesity or immobility
 Hormonal status
 History of thrombosis

Certain types of cancer show a higher probability of developing VTE than others. However, breast cancer is the entity with the greatest risk of VTE, which usually arises during systemic treatment.3

Changes in physiologic parameters such as elevated platelet and WBC counts, or reduced haemoglobin levels were shown to be indicative of chemotherapy-associated VTE.2

Another parameter broadly used is D-dimer, but the incidence of VTE related to elevated D-dimer levels varies among the different cancer types, with the highest found in colorectal cancer patients compared to others (one-year incidence of DVT 20% (95% CI, 12–31%) vs 5% (95% CI, 2–12%), respectively).4 In breast cancer patients, levels of D-dimer are higher in patients with axillary lymph node involvement compared to patients without.5 Another biomarker that might reflect the risk of VTE in breast cancer is the thrombin-antithrombin (TAT) complex in plasma, which is elevated like D-dimer.6

Tissue factor (TF), the physiologic activator of haemostasis and identified as a promoter of cancer stem cell activity, is also elevated in cancer patients and released into the circulation in the form of microparticles. Assays to assess the TF include immunohistochemical grading of TF expression on tumour cells, measurement of TF antigen using ELISA [e.g. ZYMUTEST™ Total Tissue Factor (RUO); Hyphen Biomed, A Sysmex Group Company; Neuville-sur-Oise, France], TF microparticle procoagulant activity [e.g. ZYMUPHEN™ MP-TF (RUO); Hyphen Biomed, A Sysmex Group Company; Neuville-sur-Oise, France] or flow cytometry. Studies indicate an association between elevated TF and VTE, but this is limited to certain tumour sites and stages (pancreatic and ovarian cancer) only and cannot be used for overall prediction.2

Prothrombin fragment F 1+2, urokinase-type plasminogen activator (uPA) and plasminogen activator inhibitor-1 (PAI-1) are also associated with elevated VTE risk, but their predictive value is controversial among different studies.7, 8, 9 Table 2 summarises the incidence of abnormal coagulation biomarkers in cancer patients.

Table 2 Incidence of abnormal coagulation biomarkers in cancer patients of diverse entities




D-dimer50 – 90≤ 0.5 mg/L FEU
Fibrinogen40 – 801.7 – 4.2 g/L
TAT complex40 – 70< 4 ng/mL
FDP60 – 80< 10 µg/mL
Prothrombin fragment 1+235 – 550.069 – 0.229 nmol/L
Thrombocytosis5 – 80150 – 350 x 109/L

Biomarkers support the prediction of the risk of developing VTE; however, careful patient assessment and management is essential for preventing it. Therefore, several predictive models have been established which consider levels of certain biomarkers as well as the type of cancer and other patient characteristics to support clinicians in VTE prevention. The best-known model after Khorana et al. is shown in Table 3.2

Table 3 Predictive model for chemotherapy-associated VTE



Cancer entity 
Very high risk (stomach, pancreas)2
High risk (lung, lymphoma, gynaecologic, bladder, testicular)1
Pre-chemotherapy platelet count ≥ 350 x 109/L1
Haemoglobin concentration < 100 g/L or use of erythropoiesis-stimulating agents1
Pre-chemotherapy leucocyte count > 11 x 109/L1
Body mass index ≥ 35 kg/m21

High-risk score: ≥ 3; intermediate risk score: 1–2; low-risk score: 0

Identification of novel VTE-associated biomarkers in individual malignancies is required to drive the development of cancer type-specific scoring systems with an improved predictive value.
