    ObjectivesTo assess the impact of the definition of the Global Leadership Initiative in Sarcopenia (GLIS) on mortality in esophageal cancer (EC) patients, postesophagectomy, within a Chinese cohort and to validate the effectiveness of a new GLIS framework in oncology.MethodsWe performed an observational real-world cohort study in a single center at Daping Hospital of the Army Medical University in China, spanning from December 2014 to July 2022. We used the combined definition of muscle mass and muscle strength in a new GLIS framework for the diagnosis of sarcopenia. Potential covariates were identified through univariate and multivariate analyses. The association between GLIS-defined sarcopenia and mortality was estimated using Kaplan-Meier curves and Cox models. We also conducted stratified analyses to assess the stability of multivariable Cox models.ResultsA total of 520 EC patients were included in the study, with a median follow-up of 48.7 months. A total of 229 EC patients (44.0%) were identified with GLIS-defined sarcopenia. Patients with GLIS-defined sarcopenia had significantly worse overall survival in Kaplan-Meier curves (log-rank P = 0.015). Age; sex; tumor, node, metastasis stage; blood glucose; bleeding volume in operation; and operating time were introduced as covariates in a fully adjusted Cox model. Multivariable-adjusted Cox models revealed that GLIS-defined sarcopenia was an independent prognostic factor for EC patients postesophagectomy (hazard ratio, 1.87, 95% confidence interval, 1.28-2.74, P = 0.001). Stratified analyses confirmed the stability of the relationship between GLIS-defined sarcopenia and mortality in EC patients.ConclusionsGLIS-defined sarcopenia is prevalent among Chinese EC patients and is linked to increased mortality risk postesophagectomy. This finding offers compelling evidence and serves as a valuable reference for the establishment of an operational definition of GLIS sarcopenia.Copyright © 2024 Elsevier Inc. All rights reserved.
