In a comparison of patients with Stage-1 non-small cell lung cancer (NSCLC) during the period 1999-2008, those in the last four years of that period who received radiation therapy had a median survival rate of 21 months, which was markedly better than the 16-month rate among similar patients in the first four years. These study results were presented by lead author Nirav S. Kapadia, M.D., chief resident, department of radiation oncology, University of Michigan Medical School, during the 2012 Chicago Multidisciplinary Symposium in Thoracic Oncology.
