Introduction: Cancer cachexia occurs in cancer patients more frequently as the cancer progresses, with a negative impact on treatment outcomes. In this study, we sought to clarify the clinical impact of a cancer cachexia index (CXI) in patients with gastric cancer (GC) undergoing gastrectomy. Methods: Between January 2013 and December 2018, we reviewed data from 556 patients treated for GC at our hospital. CXI was calculated using skeletal muscle index (SMI), serum albumin, and neutrophil-lymphocyte ratios (NLR). Patients were divided into high (n = 414) or low CXI (n = 142) groups. We investigated the clinical impact of CXI in patients with GC undergoing gastrectomy. Results: Multivariate analyses of 5-year overall survival (OS) and cancer-specific survival (CSS) rates indicated that a low CXI was independently associated with unfavorable outcomes for patients with GC. In multivariate analyses, SMI was independent predictor of OS but not CSS. NLR was not an independent predictor of either OS or CSS. Complication incidences (≥ Clavien Dindo 3) were non-significantly higher in the low (vs. high) CXI group. Conclusion: CXI was a more valuable prognostic biomarker when compared with SMI or NLR in GC patients undergoing gastrectomy. We suggest that patients with low CXI values should be given more comprehensive treatment, including exercise and nutritional therapy to improve clinical outcomes. [ABSTRACT FROM AUTHOR]

Objective: The aim of this study was to clarify the risk of loss of independence (LOI) following gastrectomy in elderly patients with gastric cancer (GC). Methods: In this prospective study, frailty was assessed preoperatively by a frailty index (FI) in 243 patients aged ≥ 65 years who underwent gastrectomy for GC between August 2016 and December 2020. Patients were assigned into two groups (high FI vs. low FI) to investigate frailty and the risk of LOI after gastrectomy for GC. Results: Overall and minor (Clavien–Dindo classification [CD] 1, 2) complication rates were significantly higher in the high FI group, but the two groups had similar rates of major (CD ≥ 3) complications. The frequency of pneumonia was significantly higher in the high FI group. In univariate and multivariate analyses for LOI after surgery, high FI, older age (≥ 75 years), and major (CD ≥ 3) complications were independent risk factors. A risk score assigning 1 point for each of these variables was useful in predicting postoperative LOI (LOI: score 0, 7.4%; score 1, 18.2%; score 2, 43.9%; score 3, 100%; area under the curve [AUC] = 0.765.) Conclusions: LOI after gastrectomy was independently associated with high FI, older age (≥ 75 years), and major (CD ≥ 3) complications. A simple risk score assigning points for these factors was an accurate predictor of postoperative LOI. We propose that frailty screening should be applied for all elderly GC patients before surgery.

Background: This study investigated the impact and short-term surgical outcomes of two different main energy devices for robotic gastrectomy for gastric cancer. The outcomes of robotic gastrectomy with ultrasonic shears and those of robotic gastrectomy with conventional forceps were compared.Methods: We retrospectively evaluated 171 patients who underwent robotic distal gastrectomy or total gastrectomy for gastric cancer. We classified patients into the ultrasonic shears (US) and Maryland bipolar (MB) forceps groups according to the main energy device used for robotic gastrectomy.Results: We extracted 58 patients from the US group and 58 patients from the MB forceps groups using propensity score matching. The total console time (310 min [interquartile range (IQR), 253-369 min] and 332 min, [IQR, 294-429 min]; p = 0.022) and the console time to gastrectomy (222 min [IQR, 177-266 min] and 247 min [IQR, 208-321 min]; p = 0.004) were significantly shorter in the US group than in the MB forceps group. Less blood loss occurred in the US group than in the MB forceps group (20 mL [IQR, 10-40 mL] and 30 mL [IQR, 16-80 mL]; p = 0.014). The postoperative complication rate and postoperative hospital stay length were similar between groups. A multivariate multiple linear regression analysis demonstrated that the use of an ultrasonically activated device was one an independent factor that reduced the operative time of robotic gastrectomy.Conclusion: Using ultrasonic shears as the main energy device may contribute to better surgical outcomes after robotic gastrectomy for gastric cancer.

- Abstract
Purpose: The mesentery of the jejunum (MJ) of the Roux limb is conventionally divided when Roux-en-Y reconstruction is performed after total gastrectomy for gastric cancer (GC). However, the impact of dividing or preserving the MJ on anastomotic leakage (AL) at the esophagojejunostomy (EJS) site after minimally invasive total gastrectomy for GC is unclear.Methods: This retrospective cohort study enrolled 226 patients with GC who underwent EJS after laparoscopic or robotic total gastrectomy, including preservation of the MJ (n = 87) and division of the MJ (n = 137). The prevalence of anastomotic complications at the EJS and short-term outcomes were compared between groups using propensity score (PS) matching.Results: After PS matching, 69 patients were selected for the preserving and dividing MJ groups. There were no significant intergroup differences in patient backgrounds, including oncological stage, body mass index, and gender ratio. After PS matching, overall and severe complications after surgery were compared between the preserving and dividing MJ groups (21.7% vs. 27.5%, p = 0.554 and 8.7% vs. 13.8%, p = 0.137, respectively). However, the rate of AL at the EJS was significantly lower in the preserving than that in the dividing MJ group (1.4% vs. 13.0%, p = 0.017). In addition, the median postoperative hospital stay was significantly shorter in the preserving than that in the dividing MJ group (13.0 days vs. 16.0 days, p = 0.005).Conclusions: Preserving the MJ significantly reduced AL at the EJS after minimally invasive total gastrectomy for GC.
