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]

The relationships between sarcopenia and postoperative outcomes in patients with early-stage gastric cancer who undergo radical gastrectomy is unclear. We aimed to investigate the predictive value of sarcopenia on adverse outcomes for stage I gastric cancer. The clinical data of patients who underwent radical gastrectomy for stage I gastric cancer between July 2013 and May 2019 were prospectively collected. Basic sarcopenia components were measured preoperatively. Univariate and multivariate analyses were conducted to evaluate the risk factors for short- and long-term outcomes. A total of 507 patients with early-stage gastric cancer were included in the study, and 73 (14.4%) patients were diagnosed as sarcopenia. Patients with sarcopenia had significantly higher incidence of postoperative complications (32.9% vs. 17.5%, P = 0.002), longer postoperative hospital stays (13 days vs. 12 days, P < 0.001), higher hospitalization costs (65210 yuan vs. 55197 yuan, P < 0.001) and one-year mortality (8.2% vs. 1.8%, P = 0.002). During the median follow-up time of 38.8 months, 12 (16.4%) patients dead in the sarcopenic group and 25 (5.8%) patients dead in the non-sarcopenic group. Sarcopenia was an independent risk factor for both short- and long-term clinical outcomes. Moreover, we found that low muscle quantity and low handgrip strength mediated the adverse impacts of sarcopenia on postoperative complications while low muscle quality mediated the adverse impacts of sarcopenia on overall survival. Sarcopenia was strongly associated with worse short- and long-term clinical outcomes in patients with stage I gastric cancer who undergo radical gastrectomy. F09F Sarcopenia is the only risk factor of complication in early gastric cancer. F09F Sarcopenia is one of the independent risk factors of poor oncologic outcome. F09F Low muscle mass and strength mediate the impact of sarcopenia on complication. F09F Low muscle quality mediated the impact of sarcopenia on overall survival. [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]

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. 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. 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. Sarcopenia is an independent clinical predictor of short-term postoperative complications after laparoscopic-assisted gastrectomy. [ABSTRACT FROM AUTHOR]

Background Gastrectomy results in a significant loss of body composition in the long term, but the acute skeletal muscle wasting after gastrectomy has been rarely investigated. Moreover, the association between postoperative muscle wasting and quality of life (QOL) has never been reported. In the present study, we aimed to investigate the risk factors for acute muscle wasting after gastric cancer surgery and its effect on QOL and short-term postoperative outcomes. Methods We conducted a prospective study of patients who underwent curative gastrectomy for gastric cancer between June 2015 and December 2015. Skeletal muscle mass was measured by computed tomography within 1 month before and 1 week after surgery. QOL was assessed 1, 3, and 6 months postoperatively. Univariate and multivariate analyses were performed to identify the risk factors for clinically relevant muscle wasting (muscle wasting ≥10%). Results A total of 110 patients were included, in which 35 patients had muscle wasting ≥10% within 1 week after surgery. Age ≥65 years and diabetes were independent risk factors for muscle wasting ≥10%. Patients with muscle wasting ≥10% had a poorer QOL in terms of fatigue and physical functioning at 1 and 3 months postoperatively, as well as a higher incidence of postoperative complications, a higher incidence of handgrip strength reduction ≥10%, longer hospital stays, and higher costs. Conclusions Age ≥65 years and diabetes were independently associated with clinically relevant muscle wasting within 1 week after gastric cancer surgery. Clinically relevant muscle wasting was associated with a poorer QOL and short-term outcomes after surgery. [ABSTRACT FROM AUTHOR]

Background Precise determination of the lymph node status is critical for determining appropriate treatment for early gastric cancer (EGC). This study attempted to establish a simple, effective risk scoring system to predict lymph node metastasis (LNM) in EGC by investigating the relationship between platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio (NLR) and EGC LNM. Materials and methods We retrospectively reviewed 312 operable patients with EGC. The clinical utility of PLR and NLR was tested by receiver operating characteristic curves. The scoring system was developed using independent risk factors. Finally, 89 EGC patients were collected from prospective database to validate the scoring system's accuracy. Results The optimal PLR and NLR cut-off values were 106 and 2.97, respectively. High NLR ( P = 0.009) and PLR ( P = 0.007) values were associated with LNM of EGC in univariate analyses, although only high PLR ( P = 0.025) was an independent risk factor in multivariate analyses, together with age ( P = 0.009), differentiation ( P = 0.017), invasive depth ( P < 0.001), and tumor size ( P = 0.003). The scoring system's accuracy for retrospective and prospective data was 0.781 (95% confidence interval: 0.721-0.841) and 0.817 (95% confidence interval 0.714-0.920), respectively. Conclusions Preoperative PLR and NLR correlate with EGC LNM. Our scoring system is reliable, accurate, and effective in predicting LNM in EGC patients. [ABSTRACT FROM AUTHOR]
