    EUTOS Score for Chronic Myelogenous Leukemia (CML)

    Predicts outcomes after CML treatments, specifically adjusted for tyrosine kinase treatments.
    Favorite

    INSTRUCTIONS

    Use in newly-diagnosed patients before starting therapy.

    When to Use
    Pearls/Pitfalls
    Why Use

    Newly-diagnosed CML patients prior to discussions regarding prognosis and treatment options.

    • The EUTOS (European Treatment and Outcome Study) Score predicts survival and can also be used to predict the probability of complete cytogenetic response at 18 months.
    • Has better predictive value than the Sokal Score.
    • Spleen size estimation is subjective; however, that subjectivity is also included in other CML prognostic scores.
    • Developed in patients treated with imatinib, so outcomes may not apply with newer generation therapies.
    • Estimates response to therapy to, and survival on, the reference TKI (tyrosine kinase inhibitor) imatinib.
    • Only requires two values, which can be clinically detected prior to completing a bone marrow biopsy.

    Management

    Though there is no broad consensus on management, a conservative strategy is to treat low-risk patients with imatinib and reserve newer-generation TKIs for high risk patients.

    Critical Actions

    Can only be applied to a newly-diagnosed patient before starting therapy.
