    Khorana Risk Score for Venous Thromboembolism in Cancer Patients

    Predicts risk of VTE for cancer patients depending on type of cancer and other factors.
    When to Use
    Why Use

    Patients with a cancer diagnosis starting chemotherapy.

    • Categorizes cancer patients for VTE risk.
    • Higher risk cohorts (e.g. inpatients, lower performance scores) have even higher risks than shown.
    • Most validations were completed in outpatients settings with higher risk cancer patients.

    Predicting VTE in cancer patients is complicated and likely improved by a scoring system.

    Creator Insights


    The Khorana Risk Score stratifies risk well. In outpatients, VTE risk remains relatively low (~10%) even in the highest score groups.


    At least one author group has applied a binary version of the Khorana Risk Score in practice, using the result for clinical decision making.

    Critical Actions

    The Khorana Risk Score requires multiple laboratory variables, and it may not stratify as consistently or accurately in higher risk patients and those with cancers not indicated in the score.
