NCT04479579

Brief Summary

This is a prospective, twin-center, cohort study in patients discharged from the hospital after major abdominal or pelvic cancer surgery for cancer. This study is designed to evaluate the adherence to extended deep vein thrombosis prophylaxis (DVT) with the direct oral anticoagulant apixaban on the background of historical data from the investigator's center on low-molecular-weight heparin (LMWH) substandard adherence in the same setting.
