Venous Thromboembolism and Outcomes in Glioma Patients: A Brazilian Multicenter Cohort

A 2021–2022 multicenter retrospective cohort study of 334 adults with primary gliomas treated across nine Brazilian centers, with follow-up to December 2023. The research estimates 12-month cumulative incidences of venous thromboembolism, bleeding, and all-cause mortality, evaluating determinants using multivariable models. The dataset was created by Viviane Cordeiro Veiga and shared under a CC-BY-4.0 license.

Use Cases

• Modeling venous thromboembolism risk in glioma patients based on prior VTE history and corticosteroid use.
• Analyzing bleeding risk determinants based on chronic kidney failure and diabetes mellitus status.
• Investigating mortality risk factors based on glioma type, hospitalization length, and postoperative bleeding events.
• Assessing the impact of sociodemographic factors and treatment center specialization on patient outcomes.

Strengths

• Includes data from 334 patients across nine specialized centers, providing a multicenter perspective.
• Reports specific 12-month cumulative incidence rates: 11.8% for VTE, 4.7% for bleeding, and 26.2% for mortality.
• Employs advanced statistical methods (Fine–Gray subdistribution hazard models, Cox models) accounting for competing risks.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the Brazilian cohort.
