    Attention COACH STUDY participants:

    The principal investigators of the study request that you use the official version of the modified score here.

    Eastern Cooperative Oncology Group (ECOG) Performance Status

    Determines ability of patient to tolerate therapies in serious illness, specifically for chemotherapy, simpler than the Karnofsky Scale.
    When to Use
    Pearls/Pitfalls
    Why Use

    Patients with active cancer under treatment.

    • The ECOG Performance Status is a simple measure of functional status.
    • It has scores ranging from 0 to 5, and these correlate with scores from the Karnofsky Scale’s 0-100 scores.
    • It is commonly used as a prognostic tool, as a selection criterion for cancer research, and to help determine treatment.

    Performance status is highly correlated with survival, need for services, and may help predict ability to tolerate therapies.
