Objectives Sarcopenia is characterized by progressive and generalized loss of skeletal muscle mass and strength. We aimed to investigate sarcopenia in patients with stage I non-small cell lung cancer (NSCLC) who underwent complete resection, and the relationship of sarcopenia with clinicopathological factors. Methods All consecutive patients who underwent lung resection between January 2005 and December 2008 were enrolled in this retrospective study. Eligible patients were assigned to one of 2 groups according to the presence or absence of sarcopenia, as assessed by the sum of cross-sectional areas of skeletal muscles in the region of the third lumbar vertebra (L3) on preoperative computed tomography (CT). Results Sixteen of 52 male (30.8%) and 22 of 38 female (57.9%) patients were identified with sarcopenia (p = 0.01). Patients with sarcopenia were more likely to have a low body mass index (BMI) (p < 0.0001). Kaplan-Meier analysis showed that patients with sarcopenia had a significantly worse outcome than patients without sarcopenia (5-year-survival: 72.8% vs 85.8%, respectively, p = 0.028). Multivariate analysis found that sarcopenia was a significant independent prognostic factor (hazard ratio: 7.09, p = 0.0008). Conclusions Sarcopenia identified on a cross-sectional CT image of the L3 level was associated with poor outcome with completely resected early-stage NSCLC.
