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 Adversely Impacts Postoperative Clinical Outcomes Following Gastrectomy in Patients with Gastric Cancer: A Prospective Study
Background Sarcopenia is characterized by decreased skeletal muscle plus low muscle strength and /or physical performance . This study was performed to determine the association of sarcopenia with short-term postoperative outcomes after gastrectomy for gastric cancer . Methods We conducted a prospect i ve study of 255 consecutive patients with gastric cancer who underwent curative gastrectomy .  The sarcopenia elements , including lumbar skeletal muscle index , h and grip strength , and gait speed , 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 Sarcopenia was present in 32 of 255 patients ( 12.5 % ) , and was significantly correlated with advance age , lower body mass index , higher nutritional risk screening ( NRS ) 2002 score , and lower preoperative serum albumin and hemoglobin . Compared with non-sarcopenic patients , sarcopenic patients had a higher risk of postoperative complications , longer postoperative hospital stay , and more hospital costs . In univariate analysis , sarcopenia ( p < 0.001 ) , nutritional risk ( NRS 2002 score ≥3 ; p = 0.003 ) , advanced age ( ≥75 years ; p = 0.014 ) , anemia ( p = 0.012 ) , hypoalbuminemia ( p = 0.029 ) , and diabetes ( p = 0.014 ) were associated with postoperative complications . Multivariable analysis revealed that sarcopenia ( p < 0.001 ) and diabetes ( p = 0.006 ) were independent predictors of postoperative complications . Conclusions Sarcopenia is an independent predictor of postoperative complications in patients with gastric cancer after gastrectomy
