Background: Obesity and sarcopenia are both viewed as pathological body composition issues and indicators of compromised nutritional status. The aim of this study was to evaluate the effects of sarcopenic obesity on short- and long-term clinical outcomes. Methods: The clinical data of patients who underwent radical gastrectomy between 2013 and 2019 were prospectively collected. Sarcopenia is defined by European Working Group on Sarcopenia in Older People (EWGSOP2) and obesity is defined by the body mass index (BMI). To identify the independent predictors of postoperative complications and overall survival, we performed univariate and multivariate logistic and Cox regression analyses. Results: In a total of 508 cases, 372 (73.2%) cases were diagnosed with non-sarcopenia, 112 (22.0%) with non-obese sarcopenia, and 24 (4.7%) with sarcopenic obesity. In the multivariate logistic regression, both of non-obese sarcopenia (OR = 2.305, 95% CI = 1.444–3.679, P < 0.001) and sarcopenic obesity (OR = 2.589, 95% CI = 1.088–6.156, P = 0.031) were independent risk factors for postoperative complications. In the multivariate Cox analysis, only non-obese sarcopenia (HR = 2.614, 95% CI = 1.882–3.631, P < 0.001) was independent risk factor for overall survival. Conclusions: Sarcopenic obesity serves as an independent risk factor for postoperative complications, but not for overall survival. [ABSTRACT FROM AUTHOR]

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]

Purpose: The applicability of laparoscopic-assisted radical gastrectomy for elderly patients with gastric cancer is still not well clarified. The aim of this double-center study was to explore the feasibility and effectiveness of laparoscopic-assisted radical gastrectomy on elderly patients with gastric cancer. Methods: We prospectively collected data of patients who underwent gastrectomy for cancer in two centers from June 2016 to December 2019. Propensity score matching was performed at a ratio of 1:1 to compare the laparoscopic-assisted radical gastrectomy group and open radical gastrectomy group. Univariate analyses and multivariate logistic regression analyses evaluating the risk factors for total, surgical, and medical complications were performed. Results: A total of 481 patients with gastric cancer met the inclusion criteria and were included in this study. After propensity score analysis, 258 patients were matched each other (laparoscopic-assisted radical gastrectomy (LAG) group, n = 129; open radical gastrectomy (OG) group, n = 129). LAG group had lower rate of surgical complications (P = 0.009), lower rate of severe complications (P = 0.046), shorter postoperative hospital stay (P = 0.001), and lower readmission rate (P = 0.039). Multivariate analyses revealed that anemia, Charlson comorbidity index, and combined resection were independent risk factors in the LAG group, whereas body mass index and American Society of Anesthesiology grade in the OG group. Conclusion: Laparoscopic-assisted radical gastrectomy was relative safe even effective in elderly gastric cancer patients. We should pay attention to the different risk factors when performing different surgical procedures for gastric cancer in elderly patients. [ABSTRACT FROM AUTHOR]
