Pravosud V, Vanderford NL, Huang B, et al. - Researchers conducted a population‐based, retrospective case‐control study of Kentucky patients who were diagnosed with stage IV non‐small cell lung cancer (NSCLC) between January 1, 2000, and December 31, 2011 to assess disparities in exceptional survival (ES; survival of 5 years or more past diagnosis) between stage IV NSCLC patients residing in the Appalachian vs non‐Appalachian regions of Kentucky. Results revealed no differences in the odds of ES among stage IV NSCLC patients in relation to residence in Appalachian vs non‐Appalachian Kentucky. Higher odds of ES were observed in correlation with being female and undergoing surgery only as the first course of treatment. Decreased odds of ES were observed in correlation with increasing age, unspecified histology, having poorly differentiated or undifferentiated carcinomas, and receiving radiation therapy only as the first course of treatment.
