Abstract: Objective The objective of this study was to determine the clinicopathological characteristics of advanced non-small cell lung cancer patients with sarcopenia,and to evaluate the effect of sarcopenia on progression-free survival(PFS)and overall survival(OS)in advanced non-small cell lung cancer patients. Methods A total of 112 patients with stage IIIb-IV non-small cell lung cancer who were treated in our hospital from June 2017 to December 2019 were selected,and the patients were divided into the sarcopenia group(64 cases)and the non-sarcopenia group(48 cases).All patients were followed up by telephone or outpatient service.PFS and OS between the two groups were compared.Cox regression was used to analyze the prognostic risk factors of advanced non-small cell lung cancer. Results The survival rates of PFS and OS in the group with sarcopenia were lower than those in the group without sarcopenia(P<0.05).Multivariate Cox hazard proportional regression analysis showed that sarcopenia and T stage were independent risk factors for PFS in patients with advanced non-small cell lung cancer(P<0.05);sarcopenia and lymph node metastasis were independent risk factors for OS in patients with advanced non-small cell lung cancer(P<0.05). Conclusion The PFS and OS of advanced non-small cell lung cancer patients with sarcopenia are lower than those of non-sarcopenic patients,sarcopenia may be used as a prognostic indicator for advanced non-small cell lung cancer patients.
