Abstract
Background: Tumor thrombus can be associated with an increased risk of venous thromboembolism (VTE) and poor prognosis. The risks and benefits of anticoagulation remain unclear.
Objectives: To evaluate the role of anticoagulation and associated outcomes in patients with tumor thrombus.
Methods: We conducted a single-center retrospective cohort study in patients with tumor thrombus from 2019 to 2022. All patients were followed for 12 months from the diagnosis of tumor thrombus or until death if death occurred earlier. The primary outcome was the percentage of patients prescribed any dose of anticoagulation for tumor thrombus (or concurrent bland thrombus/VTE). The secondary outcomes included new thrombosis, major bleeding, clinically relevant nonmajor bleeding, and mortality. We calculated the 6- and 12-month cumulative incidence of outcomes with 95% CI and compared those given anticoagulation vs not, considering death as a competing risk.
Results: We included 211 patients, among whom 106 (50.2%; 95% CI, 47.9%-52.6%) were given anticoagulation for tumor thrombus or concurrent VTE (present in 21.8%). The most common type of cancer was hepatocellular carcinoma (28%). Splanchnic veins were the most commonly involved (49.3%). Anticoagulation was more likely used if tumor thrombus involved the inferior vena cava and/or the heart, with concurrent VTE, or if thrombosis service was consulted. The overall 12-month incidence of new VTE was 11.4% (95% CI, 7.3%-16.5%), that of major bleeding + clinically relevant nonmajor bleeding was 36.6% (95% CI, 29.6%-43.5%), and mortality of 52.5% (95% CI, 44.8%-59.6%), with no significant differences among groups given anticoagulation or not.
Conclusion: Patients with tumor thrombus carry high risks of VTE, bleeding, and mortality. The impact of anticoagulation remains unclear.

It is dedicated to advancing science related to thrombosis, bleeding disorders, and vascular biology through the dissemination and exchange of information and ideas within the global research community.
Types of Publications:
The journal publishes a variety of content, including:
Original research reports
State-of-the-art reviews
Brief reports
Case reports
Invited commentaries on publications in the Journal
Forum articles
Correspondence
Announcements
Scope of Contributions:
Editors invite contributions from both fundamental and clinical domains. These include:
Basic manuscripts on blood coagulation and fibrinolysis
Studies on proteins and reactions related to thrombosis and haemostasis
Research on blood platelets and their interactions with other biological systems, such as the vessel wall, blood cells, and invading organisms
Clinical manuscripts covering various topics including venous thrombosis, arterial disease, hemophilia, bleeding disorders, and platelet diseases
Clinical manuscripts may encompass etiology, diagnostics, prognosis, prevention, and treatment strategies.
