A new risk-assessment tool for venous thromboembolism in advanced lung cancer: a prospective, observational study

Management of cancer-associated venous thromboembolism (VTE) is essential in treatment selection and cancer prognosis. However, to date, there is no method to assess the risk of VTE specifically associated with advanced lung cancer. Our aim was to create a new risk assessment scoring system that can predict the concomitant or incidence of VTE in advanced lung cancer. We used the dataset of 1008 patients with lung cancer in the Rising-VTE/NEJ037 study, of which 100 (9.9%) developed VTE. The items extracted in the multivariate analysis included female sex, adenocarcinoma, performance status, N factor, lymphocyte count, platelet count, prothrombin fragment 1 + 2, and diastolic blood pressure. This model had a maximum score of 8 points, with ≥ 5 points indicating a high risk of VTE. This simple risk-assessment model for VTE complications with advanced lung cancer could help identify cases that required monitoring for VTE.
