Purpose : We aimed to investigate the prevalence of sarcopenia using new diagnostic criteria and association of sarcopenia with cardiopulmonary function and physical activity (PA) in preoperative lung cancer patients.
Methods : The data of 614 patients were obtained from the CATCH-LUNG cohort study. Patients were classified into three groups—normal (n=520), pre-sarcopenia (n=60, low skeletal muscle mass index only), and sarcopenia (n=34, low SMI and strength). Cardiopulmonary function was measured using the 6-min walk test (6MWT), and PA was objectively measured using a wearable device.
Results : The adjusted odds ratio (aOR) for a <400-m distance in 6MWT was 3.52 (95% confidence interval [CI] 1.34-9.21) and 6.63 (95% CI 2.25-19.60) in the pre-sarcopenia and sarcopenia groups, respectively, compared to that in the normal group. The aOR (95% CI) for <5000 steps/day was 1.64 (0.65-4.16) and 4.20 (1.55-11.38) in the pre-sarcopenia and sarcopenia groups, respectively, compared to that in the normal group.
Conclusion : In conclusion, the prevalence of pre-sarcopenia and sarcopenia was 9.8% and 5.5%, respectively, among preoperative lung cancer patients. Cardiopulmonary function and physical activity were significantly lower in the pre-sarcopenia and sarcopenia groups than in the normal group. Patients with sarcopenia had more robust findings, suggesting the importance of muscle strength and mass.
