| Abstract: [Objective] Cancer-associated venous thromboembolism (VTE) is one of the leading causes of death in cancer patients. The purpose of this study is to construct the cAncer and VenOus thromboembolIsm Database (AVOID). [Methods] This study optimized and improved an established cohort of cancer patients at risk of catheter related thrombosis and, through expert discussions, developed the structure, inclusion and exclusion criteria, data collection, follow-up, quality control and other protocols of AVOID. [Results] AVOID comprises four sections: baseline information, blood sample information, VTE screening/monitoring data and follow-up data. It focuses on patients with late-stage (stages III–IV) cancer and regularly collects information on cancer-associated VTE screening, long-term anticoagulation therapy, quality of life, biological samples, and other related information. [Conclusion] The establishment of AVOID provides important data and sample support for predicting, preventing, and treating cancer-associated VTE in China. |
