    Pack Years Calculator

    Calculates pack years in patients with any smoking history.
    When to Use
    Why Use

    Patients who report any smoking history.

    • Standard clinical measure of quantifying smoking history.

    • Correlates with survival, particularly in patients with diagnosed lung cancer. In one study of patients with advanced lung cancer (stage IIIB/IV NSCLC), median overall survival was 10.8 months in patients with >15 pack year history, compared to 14.6 months in those with ≤15 pack year history (Janjigian 2010).
