About The Study: In this study of patients with non–small cell lung cancer, quitting smoking early was associated with lower mortality following a lung cancer diagnosis, and the association of smoking history with overall survival may have varied depending on clinical stage at diagnosis, potentially owing to the differing treatment regimens and efficacy associated with smoking exposure following diagnosis. Detailed smoking history collection should be incorporated into future epidemiological and clinical studies to improve lung cancer prognosis and treatment selection.
