Conclusion The prevalence of sarcopenia depends mostly on the diagnostic cut-off points of different criteria .
Preoperative sarcopenia is a risk factor for both long-term and short-term outcomes
Background The impact of sarcopenia on the outcome of gastrointestinal ( GI ) oncological patients is still controversial .
We aim to discuss the prevalence of sarcopenia and its relation to the oncological outcome .
Sarcopenia in overweight and obese patients is a predictive factor for postoperative complication in gastric cancer: A prospective study.
BACKGROUND Sarcopenia is a syndrome characterized by progressive and generalized loss of skeletal muscle mass and strength . This study aims to explore the prevalence of sarcopenia in overweight and obese gastric cancer ( GC ) patients and figured out the impacts of sarcopenia on the postoperative complication of overweight and obese GC patients . METHODS According to the recommended body-mass index ( BMI ) for Asian population s by WHO , we conducted a prospect i ve study of overweight and obese gastric cancer patients ( BMI ≥ 23 kg/m2 ) under curative gastrectomy from August 2014 to December 2015 . Including  lumbar skeletal muscle index , h and grip strength and gait speed as the sarcopenic components were measured before surgery . Patients were followed up after gastrectomy to gain the actual clinical outcomes . Factors contributing to postoperative complications were analyzed by univariate and multivariate analysis . RESULTS Total of 206 overweight or obese patients were enrolled in this study , 14 patients were diagnosed sarcopenia and were demonstrated having significantly association with higher risk of postoperative complications , higher hospital costs , and higher rate of 30-days readmission compared with the non-sarcopenic ones . On the basis of univariate and multivariate analysis , sarcopenia was an independent risk factor for postoperative complication of overweight and obese patients with gastric cancer ( P = 0.002 ) . CONCLUSION Sarcopenia is an independent predictor of postoperative complications in overweight or obese patients with gastric cancer after radical gastrectomy
