Kaplan-Meier curves for overall survival (OS) between different regional emphysema scores (RES) in three groups: (a) lung cancer in emphysematous region with surgical resection; (b) lung cancer in non-emphysematous region with surgical resection; (c) lung cancer with non-surgical treatment. There were significant differences in OS among patients with mild, moderate, and severe RES in surgically treated lung cancer, regardless of tumor location (p<0.01). This difference was insignificant between patients with mild RES and those with moderate/severe RES when lung cancer was treated non-surgically (p=0.90).
