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 .
Impact of visceral fat on surgical complications and long-term survival of patients with gastric cancer after radical gastrectomy
Background / objectives The aim of this study was to examine the impact of visceral fat on surgical complications and long-term survival for patients undergoing radical gastrectomy . Subjects/ methods From 2009 to 2013 , 859 patients who underwent curative resection for gastric cancer were enrolled from a prospect ively maintained data base .  Visceral fat area ( VFA ) was assessed by preoperative CT scans . Patients were divided into two groups by VFA .  Perioperative variables and postoperative outcomes were compared between the high VFA group and low VFA group . Univariable and multivariable analysis were performed to investigate independent risk factors of postoperative complications and survival . Results Some 859 patients were included in the study , 308 of whom were classified as high VFA . High VFA was correlated with advance age ( P = 0.020 ) , higher albumin levels ( P = 0.001 ) , hemoglobin levels ( P < 0.05 ) , ASA grade ( P = 0.043 ) and Charlson Comorbidity Index ( P = 0.004 ) . Relative to patients with low VFA , those with high VFA had longer surgical duration s ( P = 0.004 ) , higher rate of postoperative complications ( P = 0.004 ) , and longer hospital stays ( P = 0.004 ) . High VFA was identified as the only determinant for surgical complications by logistic regression analysis ( OR , 2.236 , 95 % CI , 1.537–3.254 ; P < 0.001 ) . Cox proportional hazards regression revealed no correlation between VFA and overall survival ( OS ) or disease-free survival ( DFS ) . Conclusions Increased VFA independently predicts surgical complications in patients after gastrectomy . However , VFA is not a prognostic biomarker of OS or DFS in patients with gastric cancer
