Purpose: The association between the age-adjusted Charlson Comorbidity Index (ACCI) and sarcopenia in patients with gastric cancer (GC) remains ambiguous. This study aimed to investigate the association between the ACCI and sarcopenia and the prognostic value in patients with GC after radical resection. In addition, this study aimed to develop a novel prognostic scoring system based on these factors., Methods: Univariate and multivariate Cox regression analyses were used to determine prognostic factors in patients undergoing radical GC resection. Based on the ACCI and sarcopenia, a new prognostic score (age-adjusted Charlson Comorbidity Index and Sarcopenia [ACCIS]) was established, and its prognostic value was assessed., Results: This study included 1068 patients with GC. Multivariate analysis revealed that the ACCI and sarcopenia were independent risk factors during the prognosis of GC (P = 0.001 and P < 0.001, respectively). A higher ACCI score independently predicted sarcopenia (P = 0.014). A high ACCIS score was associated with a greater American Society of Anesthesiologists score, higher pathologic TNM (pTNM) stage, and larger tumor size (all P < 0.05). Multivariate analysis demonstrated that the ACCIS independently predicted the prognosis for patients with GC (P < 0.001). By incorporating the ACCIS score into a prognostic model with sex, pTNM stage, tumor size, and tumor differentiation, we constructed a nomogram to predict the prognosis accurately (concordance index of 0.741)., Conclusion: The ACCI score and sarcopenia are significantly correlated in patients with GC. The integration of the ACCI score and sarcopenia markedly enhances the accuracy of prognostic predictions in patients with GC., Competing Interests: Declaration of competing interest The authors declare no competing interests., (Copyright © 2024 Society for Surgery of the Alimentary Tract.

Background: The newly released Asian Working Group for Cachexia (AWGC) criteria share similar diagnostic items with the Global Leadership Initiative on Malnutrition (GLIM) criteria. This study aims to compare the AWGC cachexia and GLIM malnutrition in patients with gastric cancer and investigate whether one diagnosis continues to be a prognostic factor in individuals diagnosed with the other condition., Methods: Data of patients who underwent radical gastrectomy for gastric adenocarcinoma were prospectively collected from 2013 to 2019. The AWGC and GLIM criteria were applied to diagnosis cachexia and malnutrition, respectively. Univariate and multivariate logistic and Cox regression were used to verify the effect of relevant factors on postoperative complications and overall survival., Results: A total of 1420 patients were included, among whom 174 (12.3 %) were diagnosed with AWGC-cachexia alone, 85 (6.0 %) were diagnosed with GLIM-malnutrition alone, and 324 (22.8 %) had both AWGC-cachexia and GLIM-malnutrition. Both AWGC-cachexia and GLIM-malnutrition were independent risk factors for complications and overall survival. When they coexisted, the odds ratios (OR) and hazard ratios (HR) tended to be higher. In the AWGC-cachexia subset, GLIM-malnutrition remained an independent risk factor (HR = 1.544, 95 % CI = 1.098-2.171, P = 0.012) for overall survival after the adjustment of confounding factors. Similarly, in the GLIM-malnutrition subset, AWGC-cachexia remained an independent risk factor for overall survival (HR = 1.697, 95 % CI = 1.087-2.650, P = 0.020). Patients with both cachexia and malnutrition had the worst overall survival., Conclusion: AWGC-cachexia and GLIM-malnutrition criteria were two non-redundancy tools in reflecting mortality risk in preoperative nutritional assessment., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Background: Cachexia is prevalent in cancer patients. The conventional diagnostic criteria for cachexia are often based on Western evidence, lacking consensus for Asian populations. This study aims to compare Asian Working Group for Cachexia (AWGC) criteria with Fearon's criteria, assessing their differences in population characteristics and prognostic impact., Methods: The clinical data of patients who underwent radical gastrectomy between 2013 and 2019 were prospectively collected. Cachexia diagnosis involves the utilization of either AWGC criteria and the previous international consensus proposed by Fearon et al. A scoring model is established based on the optional criteria according to the AWGC criteria. Univariate and multivariate logistic and Cox regression analysis were conducted to determine the independent effect factors for postoperative complications and overall survival., Results: In a total of 1330 patients, 461 met AWGC cachexia criteria and 311 met Fearon's criteria. Excluding 262 overlapping cases, those diagnosed solely with AWGC-cachexia had higher age and lower BMI, albumin, hemoglobin, and handgrip strength compared to those by Fearon's criteria alone. AWGC-cachexia independently increased the risk of postoperative complications, whereas Fearon's criteria did not. Patients with AWGC-cachexia also exhibited shorter overall survival than Fearon's criteria. The AWGC-based cachexia grading system effectively stratifies the risks of postoperative complications and mortality., Conclusions: The AWGC criteria is more effective in diagnosing cancer cachexia in the Asian population and provide better prognostic indicators., Competing Interests: Conflict of interest The authors have declared no conflicts of interest., (Copyright © 2024 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

Malnutrition in patients with gastric cancer (GC) with normal body mass index (BMI) is often ignored. This study aimed to explore the role of sarcopenia in predicting postoperative complication and long-term survival in patients with GC with normal BMI. We included patients with normal BMI (18.5 kg/m 2  ≤ BMI < 23 kg/m 2 ) who underwent radical gastrectomy between July 2014 and December 2016. Sarcopenia was assessed by muscle mass, handgrip strength, and gait speed. Kaplan-Meier survival analysis was used to analyze the association between sarcopenia and the prognosis of patients with GC. Univariate and multivariate analyses were used to identify risk factors contributing to postoperative complications and long-term survival. Overall, 267 patients with GC with normal BMI were included in this study; of which 49 (18.35%) patients were diagnosed with sarcopenia. Patients with sarcopenia had higher incidence of a major postoperative complication, longer postoperative hospital stays, and greater hospital costs. The Kaplan-Meier survival analysis showed that patients with sarcopenia had poorer overall survival than non-sarcopenia patients. Univariate and multivariate analyses showed that sarcopenia was an independent predictor for postoperative complication and long-term survival in such patients. Sarcopenia is an independent predictor for postoperative complications and long-term survival in patients with normal BMI after radical gastrectomy for GC. We recommend that patients with normal BMI should perform nutritional risk screening by sarcopenia., (© 2020 The Authors.

Objectives: Sarcopenia and metabolic syndrome (MetS) are associated with the prognosis from malignant tumors. However, evidence of the relationship between sarcopenia and MetS among gastric cancer (GC) patients following radical gastrectomy is lacking. This study assessed the association between preoperative sarcopenia and MetS among GC patients and analyzed the prognosis of patients with different malnutrition statuses., Methods: We prospectively assessed the preoperative statuses of sarcopenia and MetS among patients who underwent radical gastrectomy from July 2014 to December 2017. We combined sarcopenia and MetS to generate four groups: MetS-related sarcopenia group (MSS), sarcopenia group (S), MetS group (MS), and normal group (N)., Results: A total of 749 patients with resectable GC were included in this study. Preoperative MetS was associated with sarcopenia (p < 0.001). Multivariate logistic regression presented that MetS-related sarcopenia (OR = 2.445; p = 0.010) and sarcopenia alone (OR = 2.117; p = 0.001) were independent predictors of grade Ⅱ and above complications, while MetS alone was not (p = 0.342). Cox regression analysis revealed that MetS-related sarcopenia led to the worst prognosis in the four groups (MSS vs MS: HR = 3.555, p < 0.001; MSS vs N: HR = 2.020, p = 0.003; MSS vs S: HR = 1.763, p = 0.021). However, the MetS group had better prognosis than the normal group (MS vs N: HR = 0.568, p = 0.048)., Conclusion: Preoperative MetS was associated with sarcopenia among GC patients. MetS-related sarcopenia resulted in a significantly worse prognosis. The long-term prognoses of patients with sarcopenia were impaired by preoperative MetS, while patients without sarcopenia benefited. Thus, patients with both sarcopenia and MetS require more medical interventions., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2020 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Background: Metabolic syndrome (MetS), a public health problem, is reportedly related to an increased risk of postoperative complications after surgery. However, whether MetS have an effect on complications after gastric cancer (GC) surgery are unknown. This study aimed to investigate the effects of preoperative MetS on complications after gastrectomy., Methods: Altogether, 718 gastric cancer patients who planned to receive radical gastrectomy between June 2014 and December 2016 were enrolled, demographic and clinicopathological characteristics were analyzed. Univariate and multivariate analyses were performed to identify potential risk factors for postoperative complications. A predictive model for postoperative complications was constructed in the form of a nomogram, and its clinical usefulness was assessed., Results: Of the 628 patients ultimately included in the study (mean age 62.92 years, 450 men and 178 women), 84 were diagnosed with MetS preoperatively. Severe postoperative complications (Clavien-Dindo grade ≥II) were significantly more common in patients with MetS (41.7% versus 23.7%, P < .001). Predictors of postoperative complications included MetS (odds ratio [OR] = 1.800, P = .023), age (OR = 1.418, P = .050), Charlson score (OR = 1.787, P = .004 for 1-2 points) and anastomosis type (OR = 1.746, P = .007 for Billroth II reconstruction). The high-risk rating had a high AUC (ROC I = 0.503, ROC Ib = 0.544, ROC IIa = 0.601, ROC IIb = 0.612, ROC IIc = 0.638, ROC III = 0.735), indicating that the risk-rating model has good discriminative capacity and clinical usefulness., Conclusions: MetS was an independent risk factor for complications after gastrectomy. The nomogram and rating model incorporating MetS, Billroth II anastomosis, age, and Charlson score was useful for individualized prediction of postoperative complications., (© 2020 The Authors.

Background: In 2010, the European Working Group on Sarcopenia in Older People (EWGSOP) reached a consensus on sarcopenia (EWGSOP1). In 2018, the EWGSOP met again (EWGSOP2) to update original definition of sarcopenia. This study aimed to investigate the association of sarcopenia and survival and compare the prognostic effects of sarcopenia as defined by EWGSOP1 and EWGSOP2 after gastrectomy., Methods: We conducted a prospective study including patients who underwent curative gastrectomy for gastric cancer from August 2014 to February 2018. The sarcopenia elements, including skeletal muscle index, muscle attenuation, handgrip strength, and gait speed were measured before surgery. Patients were followed up after gastrectomy to gain the actual clinical outcomes., Results: The prevalence of sarcopenia was 17.0% and 18.9% according to the EWGSOP1 and EWGSOP2 respectively. Sarcopenia was independent risk factor for postoperative complications. Compared with EWGSOP1-sarcopenia, EWGSOP2-sarcopenia and had a higher odds ratio (OR) (2.453 vs. 1.550) in multivariate model. Area under the ROC curve of model including EWGSOP2-sarcopenia was larger than that of the model including EWGSOP1-sarcopenia (AUC 0.653 vs. 0.634, P = 0.021). For both of EWGSOP1 and EWGSOP2, sarcopenia was an independent risk factor for overall survival (OS) and disease-free survival (DFS), but EWGSOP2-sarcopenia seemed to have a higher hazard ratio (OS, 1.667 vs. 1.449; DFS, 1.603 vs. 1.563). In addition, severe sarcopenia, as defined by either EWGSOP2 or EWGSOP1, had a strong predictive power (OR 4.909 vs. 3.827) for postoperative complications. Both versions of severe sarcopenia were significantly predictive of OS and DFS in Cox analysis., Conclusion: Sarcopenia at uniform diagnosis standard was an independent risk factor for survival in patients undergoing radical gastrectomy for gastric cancer. Sarcopenia defined by EWGSOP2 criteria better predicts clinical outcomes than that defined by EWGSOP1 criteria in patients with gastric cancer after gastrectomy., Competing Interests: Conflict of interest The authors declare no conflict of interest., (Copyright © 2019 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

Background: Postsurgical gastroparesis syndrome (PGS) after subtotal gastrectomy imposes significant social and economic burdens. We aimed to investigate the relationship between preoperative blood glucose level and PGS and develop a nomogram for individualized prediction. Patients and Methods . We retrospectively analyzed 633 patients with gastric cancer who underwent subtotal gastrectomy. Preoperative blood glucose levels were evaluated via receiver operating characteristic (ROC) curve analysis. Chi-squared tests and multivariable logistic regression analyses were used to develop a predictive model for PGS, presented as a nomogram, which was assessed for its clinical usefulness., Results: Thirty-eight of 633 patients were diagnosed with PGS. Based on the ROC curve analysis, the preoperative blood glucose cutoff value for PGS was 6.25 mmol/L. The predictors of PGS included preoperative hyperglycemia (odds ratio (OR) 2.3, P = 0.03), body mass index (BMI; OR 0.21, P = 0.14 for BMI < 18.5 and OR 3.0, P = 0.004 for BMI > 24), and the anastomotic method (OR 7.3, P = 0.001 for Billroth II and OR 5.9, P = 0.15 for Roux-en-Y). The predictive model showed good discrimination ability, with a C-index of 0.710, and was clinically useful., Conclusions: Preoperative hyperglycemia effectively predicts PGS. We present a nomogram incorporating the preoperative blood glucose level, BMI, anastomotic method, and tumor size, for individualized prediction of PGS., Competing Interests: The authors declare that there is no conflict of interest regarding the publication of this paper., (Copyright © 2020 Chenchen Mao et al.)

Background: Accurate evaluation of muscle strength and function is difficult. Commonly known as sarcopenia, skeletal muscle loss is closely correlated with the prognosis of patients diagnosed with gastric cancer (GC). We wondered the correlation between skeletal muscle measures combined with computed tomography and grip strength (GS) and short-term outcomes after radical gastrectomy (RG) in patients with GC., Materials and Methods: We analyzed 594 patients with GC who underwent RG. The skeletal muscle index (SMI), skeletal muscle density (Hounsfield unit average calculation [HUAC]), and GS were measured. The skeletal muscle gauge (SMG) was created by multiplying SMI and HUAC. Logistic regression modeling and multivariate analysis were used., Results: Univariate analysis showed that low SMI, low HUAC, low GS, and low SMG were predictors of short-term complications after surgery. Compared with other muscle-related factors (AUC HUAC  = 0.559, AUC SMI  = 0.575, AUC GS  = 0.580, AUC SMG  = 0.598, AUC SMI+GS  = 0.559), low GS plus SMG (AUC GS plus SMG  = 0.614, P < 0.01) was a more accurate independent risk factor for postoperative complications. Moreover, the risk model with SMG plus GS for the diagnosis of skeletal muscle loss was superior to the other models (c-index = 0.729)., Conclusions: Skeletal muscle measures using computed tomography and GS are closely correlated with short-term outcomes of patients diagnosed with GC after RG. The model contained SMG plus GS could effectively predict for patients with GC after RG at high risk of short-term outcomes. SMG plus GS has the highest accuracy for the several evaluation methods of sarcopenia., (Copyright © 2019. Published by Elsevier Inc.)

Background: The association between sarcopenia and postoperative outcomes in patients who undergo laparoscopic-assisted gastrectomy is unclear. We aimed to determine the predictive value of sarcopenia for adverse postoperative outcomes after laparoscopic-assisted gastrectomy for gastric cancer., Materials and Methods: We prospectively collected the clinical data of patients who underwent elective radical laparoscopic-assisted gastrectomy for gastric cancer in two large centers from August 2014 to October 2017. The third lumbar vertebra skeletal muscle index, handgrip strength, and 6-m usual gait speed were measured to diagnose sarcopenia. Subsequently, we aimed to identify the risk factors for postoperative complications., Results: The study included 313 patients and 37 (11.8%) patients were classified as sarcopenic. Compared with non-sarcopenic patients, sarcopenic patients were significantly older (P < 0.001), had higher nutritional risk screening 2002 scores (P = 0.013), Charlson comorbidity index (CCI) scores (P = 0.033), and neutrophil to lymphocyte ratio (P = 0.004), and lower body mass index (P < 0.001), preoperative serum albumin (P < 0.001), and hemoglobin (P < 0.001). Sarcopenic patients had higher postoperative complication rate (P = 0.002), longer postoperative hospital stays (P = 0.020) and higher total cost of hospitalization (P = 0.001). Multivariate analysis revealed that CCI score ≥1 (odds ratio [OR]: 2.424, 95% confidence interval [CI]: 1.309-4.487; P = 0.005) and sarcopenia (OR: 2.752, 95% CI: 1.274-5.944; P = 0.010) were independent risk factors for short-term postoperative complications., Conclusion: Sarcopenia is an independent clinical predictor of short-term postoperative complications after laparoscopic-assisted gastrectomy., (Copyright © 2019 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Objective: The aim of this study was to investigate the prevalence of sarcopenia in patients without nutritional risk and the association between sarcopenia and postoperative outcomes after radical gastrectomy in these patients., Method: We conducted a study of non-nutritional risk patients with gastric cancer who underwent gastrectomy from August 2014 to December 2017 in two centers. Nutritional Risk Screening 2002 (NRS 2002) was used to evaluate the nutritional risk. Patients who with NRS 2002 score <3 were classified as having no nutritional risk and were included in the study. Demographic and perioperative data were gathered. Sarcopenia was diagnosed based on the European Working Group on Sarcopenia in Older People criteria. Univariate and multivariate analysis were performed to determine the association between preoperative risk factors and postoperative complications., Results: In all, 545 patients were included, in which the prevalence of sarcopenia and postoperative complications was 7.3% and 21.1%, respectively. Sarcopenia was significantly associated with higher age, lower body mass index, lower handgrip strength, lower usual walking speed, longer postoperative hospital length of stay, and higher costs. Multivariate analysis of prognostic factors revealed that sarcopenia was an independent predictor (odds ratio, 2.330; 95% confidence interval, 1.132-4.796; P = 0.022] for postoperative complications. Male sex, diabetes, and preoperative anemia also were risk factors for postoperative complications., Conclusion: Sarcopenia was a significant independent risk factor for postoperative complications after gastrectomy in patients without nutritional risk. Preoperative assessment and management of sarcopenia should be helpful for improving clinical outcomes for patients without nutritional risk., (Copyright © 2018 Elsevier Inc. All rights reserved.)

Objective: This study aimed to determine the risk of severe postoperative complications (SPCs) in patients with gastric cancer and to construct a nomogram based on independently related factors to identify high-risk patients., Methods: We conducted a prospective study of 636 consecutive patients with gastric cancer who underwent radical gastrectomy. Degrees of sarcopenia and obesity were calculated before surgery. Factors contributing to SPCs were determined using univariate and multivariate analysis. A nomogram consisting of the independent risk factors was constructed to quantify the individual risk of SPCs., Results: Logistic analysis revealed that sarcopenic obesity, age, open surgery, and combined resection were independent prognostic factors for SPCs. Sarcopenic obese patients have the highest risk in all patients (sarcopenic obesity vs normal, OR = 6.575 p = 0.001; sarcopenic obesity vs obesity, OR = 5.833 p = 0.001; sarcopenic obesity vs sarcopenia, OR = 2.571 p = 0.032), while obese patients share the similar rate of SPCs with normal people (obesity vs normal, OR = 1.056 p = 0.723). The nomogram we constructed was able to quantify the risk of SPCs reliably (c-index, 0.737)., Conclusions: Sarcopenic obesity, together with age, open surgery, and combined resection are independent predictors of SPCs. Obesity will significantly increase the risk of SPCs in sarcopenic patient with gastric cancer, but it will not bring higher risk to normal patients. Our nomogram is a simple and practical instrument to identify patients at high risk of surgical complications.

Background: Gait speed is a clinical outcome that can measure the physical performance of elderly gastric patients. The purpose of this study was to determine the importance of gait speed in predicting post-operative morbidities in elderly patients undergoing curative gastrectomy., Methods: We conducted a prospective study of 357 elderly patients (≥65 years old) undergoing curative gastrectomy. Preoperative gait speed was measured in a 6-m well-lit and unobstructed hallway. Patients were followed up for the post-operative clinical outcomes. Factors contributing to the post-operative morbidities were analysed using univariate and multivariate analyses., Results: Slow gait speed was present in 95 out of 357 patients (26.61%) which was significantly associated with age (P < 0.001), gender (P = 0.016), plasma albumin (P < 0.001), American Society of Anesthesiologists grade (P = 0.012), tumour-node-metastasis grade (P = 0.007), sarcopenia (P < 0.001), handgrip (P < 0.001) and post-operative medical complications (P = 0.022). In univariate analysis, age (P = 0.015) and slow gait speed (P = 0.029) were risk factors of post-operative complications. In multivariate analysis, we found that age (P < 0.001) and slow gait speed (P = 0.029) were independent predictors of post-operative medical complications., Conclusion: Slow gait speed is an independent predictor of post-operative medical complications in elderly patients undergoing curative gastrectomy. Those patients should be managed with appropriate perioperative nutritional support and physical exercise which can improve gait speed and reduce the risk of post-operative medical complications., (© 2017 Royal Australasian College of Surgeons.)

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 prospectively maintained database. 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 durations (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.

Background: This study aimed to determine the relationship between intra-abdominal infection (IAI) and sarcopenia prospectively and to construct a nomogram to identify patients at a high risk of IAI., Methods: We conducted a prospective study of 682 consecutive patients with gastric cancer who underwent radical gastrectomy. The sarcopenia elements, including lumbar skeletal muscle index, handgrip strength, and gait speed, were measured before surgery. Factors contributing to IAI were determined through univariate and multivariate analysis. A nomogram consisting of the independent risk factors was constructed to quantify the individual risk of IAI., Results: Of the 682 patients enrolled in this study, 132 patients were diagnosed with sarcopenia and 61 were diagnosed with IAI. Logistic analysis revealed that sarcopenia, tumor size, pathological type, and multivisceral resection were independent prognostic factors for IAI. The nomogram model for IAI was able to reliably quantify the risk of IAI with a strong optimism-adjusted discrimination (concordance index, 0.736)., Conclusions: Sarcopenia is an independent predictor of IAI. Our nomogram was a simple and practical instrument to quantify the individual risk of IAI and could be used to identify patients at a high risk.

Background and Objectives: The study aimed to investigate the relationship between obesity and postsurgical gastroparesis syndrome (PGS), and to construct a scoring system and a risk model to identify patients at high risk., Methods: A total of 634 patients were retrospectively analyzed. Clinical characteristics were evaluated via receiver operating characteristic (ROC) curve analysis. Logistic analysis was performed to determine the independent predictive indicators of PGS. A scoring system consisting of these indicators and a risk-rating model were constructed and evaluated via ROC curve analysis., Results: Based on the ROC curves, the visceral fat area (VFA) cutoff value for PGS was 94.00. Logistic analysis showed that visceral obesity (VFA ≥ 94.00 cm 2 ), the reconstruction technique, and tumor size were independent prognostic factors for PGS. The scoring system could predict PGS reliably with a high area under the ROC curve ([AUC] = 0.769). A high-risk rating had a high AUC (AUC I = 0.56, AUC II = 0.65, and AUC III = 0.77), indicating that the risk-rating model could effectively screen patients at high risk of PGS., Conclusions: Visceral obesity defined by VFA effectively predicted PGS. Our scoring system may be a reliable instrument for identifying patients most at risk of PGS., (© 2017 Wiley Periodicals, Inc.)

Background: A geriatric assessment is needed to identify high-risk elderly patients with gastric cancer. However, the current geriatric assessment has been considered to be either time-consuming or subjective. The present study aimed to investigate the predictive effect of sarcopenia on the postoperative complications for elderly patients who underwent radical gastrectomy., Materials and Methods: We conducted a prospective study of patients who underwent radical gastrectomy from August 2014 to December 2015. Computed tomography-assessed lumbar skeletal muscle, handgrip strength, and gait speed were measured to define sarcopenia., Results: Sarcopenia was present in 69 of 240 patients (28.8%) and was associated with lower body mass index, lower serum albumin, lower hemoglobin, and higher nutritional risk screening 2002 scores. Postoperative complications significantly increased in the sarcopenic patients (49.3% versus 24.6%, P < 0.001), compared with nonsarcopenic patients. The multivariate analysis demonstrated that sarcopenia (odds ratio: 2.959, 95% CI: 1.629-5.373, P < 0.001) and the Charlson comorbidity index ≥2 (odds ratio: 3.357, 95% CI: 1.144-9.848, P = 0.027) were independent risk factors for postoperative complications., Conclusions: Sarcopenia, presented as a new geriatric assessment factor, was a strong and independent risk factor for postoperative complications of elderly patients with gastric cancer., (Copyright © 2016 Elsevier Inc.

Background: The association between sarcopenia and postoperative outcomes has been well reported. However, the impact of different sarcopenia stages on postoperative outcomes has never been investigated., Methods: We conducted a large, prospective study of patients who underwent radical gastrectomy for gastric cancer from August 2014 to December 2015. Sarcopenia was staged as "presarcopenia," "sarcopenia," and "severe sarcopenia" according to the definition of the European Working Group on Sarcopenia in Older People. Univariate and multivariate analyses evaluating the risk factors for total, surgical, and medical complications were performed., Results: A total of 470 patients were included, in which 20.6%, 10%, and 6.8% of the patients were identified as having "presarcopenia," "sarcopenia," and "severe sarcopenia," respectively. Postoperative complications, duration of hospital stays, and costs increased with advancing sarcopenia stages. Severe sarcopenia, visceral fat area to total abdominal muscle area ratio, American Society of Anesthesiologists grade III, and tumor located at the cardia were independent risk factors for total complications. Visceral fat area to total abdominal muscle area ratio and tumor located at the cardia were independent risk factors for operative complications. Presarcopenia, sarcopenia, and severe sarcopenia were all identified as independent risk factors for medical complications, as well as age ≥75 years and Charlson Comorbidity Index., Conclusion: Patients had worse postoperative outcomes after gastric cancer operation with advancing sarcopenia stages. Severe sarcopenia, but not presarcopenia or sarcopenia, was an independent risk factor for total postoperative complications. The 3 sarcopenia stages independently influence medical but not surgical complications. Recognizing sarcopenia stages is important for preoperative risk stratification., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Purpose: This study was performed to determine the association of frailty and nutritional status with postoperative complications after total gastrectomy (TG) with D2 lymphadenectomy in patients with gastric cancer., Methods: Patients undergoing TG with D2 lymphadenectomy for gastric cancer between August 2014 and February 2016 were enrolled. Frailty was evaluated by sarcopenia which was diagnosed by a combination of third lumbar vertebra muscle index (L3 MI), handgrip strength, and 6-m usual gait speed. Nutritional status was evaluated by the nutritional risk screening 2002 (NRS 2002) score. Univariate and multivariate analyses evaluating the risk factors for postoperative complications were performed., Results: A total of 158 patients were analyzed, and 27.2 % developed complications within 30 days of surgery. One patient died within 30 days of the operation. In the univariate analyses, NRS 2002 score ≥3 (OR = 2.468, P = 0.012), sarcopenia (OR = 2.764, P = 0.008), and tumor located at the cardia (OR = 2.072, P = 0.046) were associated with the postoperative complications. Multivariable analysis revealed that sarcopenia (OR = 3.084, P = 0.005) and tumor located at the cardia (OR = 2.347, P = 0.026) were independent predictors of postoperative complications., Conclusions: This study showed a significant relationship between postoperative complications and geriatric frailty using sarcopenia in patients with gastric cancer after TG with D2 lymphadenectomy. Frailty should be integrated into preoperative risk assessment and may have implications in preoperative decisionmaking.

Currently, the association between sarcopenia and long-term prognosis after gastric cancer surgery has not been investigated. Moreover, the association between sarcopenia and postoperative complications remains controversial. This large-scale retrospective study aims to ascertain the prevalence of sarcopenia and assess its impact on postoperative complications and long-term survival in patients undergoing radical gastrectomy for gastric cancer. From December 2008 to April 2013, the clinical data of all patients who underwent elective radical gastrectomy for gastric cancer were collected prospectively. Only patients with available preoperative abdominal CT scan within 30 days of surgery were considered for analysis. Skeletal muscle mass was determined by abdominal (computed tomography) CT scan, and sarcopenia was diagnosed by the cut-off values obtained by means of optimum stratification. Univariate and multivariate analyses evaluating risk factors of postoperative complications and long-term survival were performed. A total of 937 patients were included in this study, and 389 (41.5%) patients were sarcopenic based on the diagnostic cut-off values (34.9 cm²/m² for women and 40.8 cm²/m² for men). Sarcopenia was an independent risk factor for severe postoperative complications (OR = 3.010, P < 0.001), but not for total complications. However, sarcopenia did not show significant association with operative mortality. Moreover, sarcopenia was an independent predictor for poorer overall survival (HR = 1.653, P < 0.001) and disease-free survival (HR = 1.620, P < 0.001). Under the adjusted tumor-node-metastasis (TNM) stage, sarcopenia remained an independent risk factor for overall survival and disease-free survival in patients with TNM stage II and III, but not in patients with TNM stage I. Sarcopenia is an independent predictive factor of severe postoperative complications after radical gastrectomy for gastric cancer. Moreover, sarcopenia is independently associated with overall and disease-free survival in patients with TNM stage II and III, but not in patients with TNM stage I., Competing Interests: The authors have no conflicts of interest to disclose.

Background: The aim of this study was to evaluate the short- and long-term outcomes after total gastrectomy (TG) with D2 lymphadenectomy., Methods: Patients undergoing TG with D2 lymphadenectomy for gastric cancer between December 2008 and December 2011 were enrolled. Univariate and multivariate analyses were performed to evaluate the risk factors for the short- and long-term outcomes., Results: A total of 229 patients were analyzed, and 22.3 % developed complications within 30 days of surgery. No patient died within 30 days, while 2.6 % died within 90 days of the operation. In the multivariate analysis, age ≥65 years and cardiopulmonary comorbidities were associated with morbidity, whereas hypoproteinemia and tumor-node-metastasis (TNM) stage III were associated with the disease-free survival (DFS) and overall survival (OS). The number of preoperative risk factors stratified the morbidity from 10.3 % in those without any risk factors to 40.5 % in patients with both risk factors. Similarly, 5-year survival rates decreased from 68.9 % (DFS) and 71.1 % (OS) in those without risk factors to 20.2 % (DFS) and 22.9 % (OS) in patients with both risk factors., Conclusion: TG with D2 lymphadenectomy has acceptable short- and long-term outcomes. Patient risk stratification may allow for more rational selection of patients and therapeutic strategies for gastric resection.

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 prospective study of 255 consecutive patients with gastric cancer who underwent curative gastrectomy. The sarcopenia elements, including lumbar skeletal muscle index, handgrip 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.

Currently, there is a paucity of study investigating postoperative ileus in gastric cancer surgery. This prospective study aims to identify the risk factors for prolonged postoperative ileus (PPOI) and to use these risk factors to generate a risk stratification scoring system for the occurrence of PPOI.Patients who underwent radical gastrectomy for gastric cancer were included in this study. A multivariate logistic analysis was applied to identify independent risk factors for PPOI and to generate the scoring system. A receiver operating characteristic curve was generated and the area under the curve was calculated to demonstrate the predictive power of the scoring system.Finally, 296 patients were included and analyzed, of whom 96 (32.4%) developed PPOI. The multivariate analysis showed that age ≥65 years, operative duration ≥4 hours, tumor-node-metastasis (TNM) stage = III, open/converted operative technique, and total postoperative opiates dose (TOD) ≥0.3 mg/kg were independent risk factors for PPOI. Based on these factors, a risk stratification scoring system was generated, classified by low-risk (score 0-2), moderate-risk (score 3-4), and high-risk (score 5-6) groups. The incidence of PPOI increased by 7.5-fold from low-risk to high-risk group. The area under the curve of the scoring system was 0.841 (95% CI, 0.793-0.890), indicating a good predictive capability for the occurrence of PPOI.We have identified independent risk factors for the occurrence of PPOI and used these factors to construct a risk stratification scoring system.

Malnutrition is common in the patients with gastric cancer. Radical gastrectomy remained the primary strategy of curable treatment for gastric cancer. This study is performed to explore the effect of laparoscopic radical gastrectomy on clinical outcomes in gastric cancer patients with malnutrition. Gastric cancer patients with GLIM-defined malnutrition between 2014 and 2019 at our center were enrolled. The patients were divided into two groups according to the different type of surgery. Propensity score match analysis was used to balance the clinicopathologic characteristics of two groups. Postoperative outcomes and survival were compared. Multivariate analysis was used to independent risk factors of complication, overall survival (OS), and disease-free survival (DFS). Compared with patients underwent open radical gastrectomy, patients who underwent laparoscopic radical gastrectomy had lower rate of total, surgical and severe complications. They also had shorter postoperative hospital stay with better OS and DFS. Hypoalbuminemia (P = 0.003) was the independent risk factor of complications. Old age (≥75, P = 0.035) and TNM stage (III: P < 0.001, II: P = 0.015) were the independent risk factors of OS. Combined resection (P = 0.003) and TNM stage (III: P < 0.001, II: P = 0.001) posed independent risk factors of lacking DFS. Laparoscopic surgery proved to be the independent protective factor of complications (P = 0.014), OS (P < 0.001) and DFS (P < 0.001). Laparoscopic radical gastrectomy was relative safe and showed favorable outcomes in malnourished gastric cancer patients. [ABSTRACT FROM AUTHOR]

Objective: Our objective is to validate the effectiveness of the Global Leadership Initiative on Malnutrition (GLIM) criteria in malnutrition diagnosis compared with Patient-Generated Subjective Global Assessment (PG-SGA) and assess the impact of malnutrition diagnosed using GLIM criteria on the clinical outcomes of patients with GC.Methods: We retrospectively analyzed the data of 895 patients who underwent radical gastrectomy at the First Affiliated Hospital of Wenzhou Medical University. Nutrition assessment was performed on all patients according to the GLIM criteria and PG-SGA. The κ statistic was used to evaluate the agreement between two methods. Multivariate logistic regression and Cox regression based on single-factor analysis were used to predict postoperative complications and overall survival rates.Results: Based on the GLIM criteria, 38.3% of the patients were diagnosed as malnourished, including 21.7% Stage I (moderate malnutrition) and 16.6% Stage II (severe malnutrition). GLIM criteria had a moderate agreement with PG-SGA (κ = 0.548). Patients in the Stage II malnutrition group had a higher incidence of complications, a longer postoperative length of stay, and higher hospitalization costs. Logistic regression showed that Stage II malnutrition was an independent risk predictor of postoperative complications (odds ratio, 3.28; 95% confidence interval [CI], 2.18-4.94). Furthermore, Cox regression analysis showed that both Stage I (hazard ratio [HR], 1.52; 95% CI, 1.11-2.07; P = .009) and Stage II (HR, 1.85; 95% CI, 1.34-2.53; P < .001) malnutrition were independent risk predictors of overall survival.Conclusion: Diagnosis of malnutrition according to the GLIM criteria is useful in predicting the adverse postoperative clinical outcomes of patients with gastric cancer.

Objectives: The present study aimed to explore the association between spleen density and post-operative outcomes of patients after curative gastrectomy. Methods: From June 2014 to December 2015, we conducted a retrospective study to analyze pertinent clinical data from gastric cancer patients who underwent gastrectomy at the First and the Second Affiliated Hospital of Wenzhou Medical University. Spleen density was determined via computed tomography scans. Univariate and multivariate analyses were performed to determine the risk factors associated with post-operative outcomes after gastric cancer surgery. Results: Three hundred and ninety five patients were included, of whom 98 (24.8%) were defined as having a diffuse reduction of spleen density based on diagnostic cutoff values (spleen density ≤43.89 HU). Multivariate analysis revealed diffuse reduction of spleen density as an independent risk factor for post-operative complications and long-term overall survival. Conclusions: Spleen density can predict severe postoperative complications and long-term overall survival in gastric cancer patients. As an imaging evaluation method, spleen density is a novel tool can be used in clinical as a prognostic predictor for patients with gastric cancer. [ABSTRACT FROM AUTHOR]

Background: Enhanced recovery after surgery (ERAS) reduces postoperative stress, increases patient satisfaction, and reduces postoperative stay and cost. In this study, we evaluated the feasibility and effectiveness of ERAS protocols compared with conventional perioperative care group and their effect in gastric cancer patients undergoing gastrectomy.Methods: A cohort of 366 patients were analyzed from a prospectively maintained database. The patients' characteristics, tumor profile, surgical information data and postoperative complications were evaluated.Results: Patients in the ERAS had a faster gastrointestinal function recovery and first flatus (3.26±0.64; P<0.001). Pain intensity of patients in the ERAS group was significantly lower than that of patients in the conventional care group on postoperative days 1 (2.33±0.98; P<0.001) and 3 (1.06±0.63; P<0.001). Postoperative hospital stays were significantly shorter in patients receiving ERAS program (6.66±3.36; P<0.001), than in those patients who received conventional perioperative care (9.02±2.61).Conclusion: ERAS can reduce postoperative stress, enhance the recovery of the gut, reduce the pain intensity, and increase satisfaction in gastric cancer patient undergoing curative gastrectomy.

Background: Hospital readmission is gathering increasing attention as a measure of health care quality and a potential cost-saving target. The purpose of this prospective study was to determine risk factors for readmission within 30 days of discharge after gastrectomy for patients with gastric cancer. Methods: We conducted a prospective study of patients undergoing radical gastrectomy for gastric cancer from October 2013 to November 2014 in our institution. The incidence, cause and risk factors for 30-day readmission were determined. Results: A total of 376 patients were included in our analysis without loss in follow-up. The 30-day readmission rate after radical gastrectomy for gastric cancer was 7.2% (27of 376). The most common cause for readmission included gastrointestinal complications and postoperative infections. On the basis of multivariate logistic regression analysis, preoperative nutritional risk screening 2002 score ≥ 3 was an independent risk factor for 30-day readmission. Factors not associated with a higher readmission rate included a history of a major postoperative complication during the index hospitalization, prolonged primary length of hospital stay after surgery, a history of previous abdominal surgery, advanced age, body mass index, pre-existing cardiopulmonary comorbidities, American Society of Anesthesiology grade, type of resection, extent of node dissection and discharge disposition. Conclusions: Readmission within 30 days of discharge after radical gastrectomy for gastric cancer is common. Patients with nutritional risk preoperatively are at high risk for 30-day readmission. Preoperative optimization of nutritional status of patients at nutritional risk may effectively decrease readmission rates. [ABSTRACT FROM AUTHOR]
