    Why Use

    Survival for patients with malignant pleural effusion (MPE) is variable, and treatment is invasive, uncomfortable, and affects quality of life. Better understanding of survival can help inform treatment decisions.

    Advice

    • For patients in whom malignant status is suspected, Light’s Criteria may provide initial confirmation before definitive diagnosis.
    • Consider palliative care consultation for patients with metastatic disease.

    Management

    Consider prognosis in discussion of treatment options. Patients with high risk and low predicted survival may opt for permanent indwelling pleural catheter or therapeutic aspiration for minimizing hospital stay versus attempted pleurodesis.
