Cancer-related Thromboembolic Disease

Patients with cancer are at particularly high risk of venous thromboembolism (VTE). The guidelines therefore strongly recommend thromboprophylaxis but recent surveys clearly show that oncologists are reluctant to use it because of concern over bleeding, absence of validated risk stratification tools and uncertainties concerning the optimal thromboprophylaxis. Hence, it is a real challenge to identify the individual VTE risk of each cancer patient and individually tailor their thromboprophylaxis. The study aims to identify thrombin generation test (TGT) as a reliable, standardized overall haemostasis assay that can be used to evaluate individual thrombosis risk The secondary objectives are: * To define the limits of TGT parameters that indicate thrombosis risk in cancer patients * To evaluate values of other clotting activation markers in patients with cancer Patients recently diagnosed with locally advanced or metastatic adenocarcinoma of any origin, who are scheduled for systemic chemotherapy, will be enrolled in the trial at baseline (Visit 1). Thrombin generating capacity will be measured within the first month following diagnosis and before the start of the chemotherapy (between Visit 1 and Visit 2) and subsequently at the end of the first cure line of chemotherapy (Visit 3). Patients will be followed up for a period of 1 year, or until the occurrence of a thromboembolic event. Two follow up visits are foreseen - 6-month (Visit 4) and 12-month (or at the end of trial - Visit 5) visits. Patients eventually undergoing second-line chemotherapy during the course of the follow-up will remain on study. The study will document all cases of symptomatic thromboembolic events together with the relevant diagnostic work-up.
