Duan C, Wu M, Wen X, Zhuang L, Sun J. Sarcopenic obesity predicts short- and long-term outcomes after neoadjuvant chemotherapy and surgery for gastric cancer. Jpn J Clin Oncol 2024:hyae080. [PMID: 38941323 DOI: 10.1093/jjco/hyae080] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/14/2024] [Accepted: 06/26/2024] [Indexed: 06/30/2024] Open
Abstract
BACKGROUND Sarcopenic obesity (SO) affects outcomes in various malignancies. However, its clinical significance in patients undergoing neoadjuvant chemotherapy (NAC) for locally advanced gastric cancer (LAGC) remains unclear. This study investigated the impact of pre- and post-NAC SO on postoperative morbidity and survival. METHODS Data from 207 patients with LAGC, who underwent NAC followed by radical gastrectomy between January 2010 and October 2019, were reviewed. Skeletal muscle mass and visceral fat area were measured pre- and post-NAC using computed tomography to define sarcopenia and obesity, the coexistence of which was defined as SO. RESULTS Among the patients, 52 (25.1%) and 38 (18.4%) developed SO before and after NAC, respectively. Both pre- (34.6%) and post- (47.4%) NAC SO were associated with the highest postoperative morbidity rates; however, only post-NAC SO was an independent risk factor for postoperative morbidity [hazard ratio (HR) = 9.550, 95% confidence interval (CI) = 2.818-32.369; P < .001]. Pre-NAC SO was independently associated with poorer 3-year overall [46.2% vs. 61.3%; HR = 1.258 (95% CI = 1.023-1.547); P = .049] and recurrence-free [39.3% vs. 55.4%; HR 1.285 (95% CI 1.045-1.579); P = .017] survival. CONCLUSIONS Pre-NAC SO was an independent prognostic factor in patients with LAGC undergoing NAC; post-NAC SO independently predicted postoperative morbidity.

Abstract
BACKGROUND The role of minimally invasive surgery using robotics versus laparoscopy in resectable gastric cancer patients with a high body mass index (BMI) remains controversial. METHODS A total of 482 gastric adenocarcinoma patients with BMI ≥ 25 kg/m2 who underwent minimally invasive radical gastrectomy between August 2016 and December 2019 were retrospectively analyzed, including 109 cases in the robotic gastrectomy (RG) group and 321 cases in the laparoscopic gastrectomy (LG) group. Propensity score matching (PSM) with a 1:1 ratio was performed, and the perioperative outcomes, lymph node dissection, and 3-year overall survival (OS) and disease-free survival (DFS) rates were compared. RESULTS After PSM, 109 patients were included in each of the RG and LG groups, with balanced baseline characteristics. Compared with the LG group, the RG group had similar intraoperative estimated blood loss [median (IQR) 30 (20-50) vs. 35 (30-59) mL, median difference (95%CI) - 5 (- 10 to 0)], postoperative complications [13.8% vs. 18.3%, OR (95%CI) 0.71 (0.342 to 1.473)], postoperative recovery, total harvested lymph nodes [(34.25 ± 13.43 vs. 35.44 ± 14.12, mean difference (95%CI) - 1.19 (- 4.871 to 2.485)] and textbook outcomes [(81.7% vs. 76.1%, OR (95%CI) 1.39 (0.724 to 2.684)]. Among pathological stage II-III patients receiving chemotherapy, the initiation of adjuvant chemotherapy in the RG group was similar to that in the LG group [median (IQR): 28 (25.5-32.5) vs. 32 (27-38.5) days, median difference (95%CI) - 3 (- 6 to 0)]. The 3-year OS (RG vs. LG: 80.7% vs. 81.7%, HR = 1.048, 95%CI 0.591 to 1.857) and DFS (78% vs. 76.1%, HR = 0.996, 95%CI 0.584 to 1.698) were comparable between the two groups. CONCLUSION RG conferred comparable lymph node dissection, postoperative recovery, and oncologic outcomes in a selected cohort of patients with BMI ≥ 25 kg/m2.

Abstract
BACKGROUND Gastric cancer is a global health concern with varying clinical outcomes. This study aims to investigate the influence of preoperative Body Mass Index (BMI) on survival in patients who underwent curative resection for gastric cancer in Eastern India. METHODS Data from a prospectively maintained Surgical Oncology database were analysed for patients who underwent curative resection for primary gastric adenocarcinoma between May 2016 and March 2022. Patients with incomplete data were excluded. Preoperative BMI was categorised into three groups: Underweight (< 18.5 kg/m2), Normal (18.5-22.9 kg/m2), and Overweight/Obese (=23 kg/m2). Clinicopathological details, short-term outcomes, and long-term oncological outcomes were assessed. Statistical analysis included survival estimates, Cox proportional hazard models, and subgroup analysis. RESULT Of 162 patients, 145 met the inclusion criteria. Patients were predominantly male (68%) with middle or lower socioeconomic status. No significant differences amongst BMI groups were observed in performance score, tumour grade, clinical stage, or short-term outcomes. Postoperative complications and 30-day mortality were similar. However, underweight patients had poorer 4-year disease-free survival (DFS) compared to overweight/obese patients (14.3% vs. 39.7%, p = 0.03). Overweight/obese patients showed significantly better 4-year overall survival (OS) than underweight patients (47.8% vs. 20.4%, p = 0.03). CONCLUSIONS In Eastern Indian gastric cancer patients undergoing curative resection, preoperative higher BMI (overweight/obese) was associated with better long-term survival. Understanding these findings could guide tailored interventions to improve outcomes in this population.

Superior lymph node harvest by fluorescent lymphography during minimally invasive gastrectomy for gastric cancer patients with high body mass index. Gastric Cancer 2024; 27:622-634. [PMID: 38502275 DOI: 10.1007/s10120-024-01482-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/17/2023] [Accepted: 02/14/2024] [Indexed: 03/21/2024]
Abstract
BACKGROUND Fluorescent lymphography (FL) using indocyanine green (ICG) allows for the visualization of all draining lymph nodes (LNs), thereby increasing LN retrieval. However, no studies have assessed the efficacy of FL in high body mass index (BMI) gastric cancer patients, even as LN yield decreases with increasing BMI in gastrectomy. This study aimed to investigate the influence of FL on LN retrieval in high BMI gastric cancer patients. METHODS Gastric cancer patients who underwent laparoscopic or robotic gastrectomies from 2013 to 2021 were included. Patients were classified into two groups, with FL (FL group) or without FL (non-FL group). The effect of FL on LN retrieval was assessed by BMI. Inverse probability of treatment weighting (IPTW) was used to ensure comparability between groups. RESULTS Retrieved LN number decreased as BMI increased regardless of FL application (P < 0.001). According to the IPTW analysis, the mean retrieved LN number was significantly higher in the FL group (48.4 ± 18.5) than in the non-FL group (39.8 ± 16.3, P < 0.001), irrespective of BMI. The FL group exhibited a significantly higher proportion of patients with 16 or more LNs (99.5%) than the non-FL group (98.1%, P < 0.001). The FL group also had a significantly higher proportion of patients with 30 or more LNs (86.6%) than the non-FL group (72.2%, P < 0.001). In both the normal and high-BMI patients, the FL group had a significantly larger percentage of patients with a higher nodal classification than the non-FL group. CONCLUSION FL resulted in more LN retrieval, even in high BMI patients. FL ensures accurate staging by maintaining the appropriate retrieved LN number in high BMI gastric cancer patients.

Abstract
Various factors contribute to different types of surgical site infections (SSI) in gastric cancer patients undergoing surgery, and the risk factors remain uncertain. This meta-analysis aims to clarify the relationship between various factors and SSI, resolving existing controversies. Thirty-four eligible articles with 66 066 patients were included in the meta-analysis. Significant risk factors for SSI included age ≥65 years, male gender, BMI ≥25 kg/m2, diabetes, hypertension, advanced TNM stage ≥III, pathologic T stage ≥T3, pathologic N stage ≥N1, ASA ≥3, open surgery, blood transfusion, extensive resection, combined resection, splenectomy, D2 or more lymph node dissection, and operative time ≥240 min. Operative time showed a nonlinear relationship with SSI risk. Subgroup analysis revealed significant differences in the effects of risk factors among different infection types. These findings inform the development of targeted preventive measures to reduce SSI rates.

Abstract
PURPOSE This study aims to investigate the predictive value of the combined index smni(skeletal muscle index (SMI)-prognostic nutrition index(PNI)) for the postoperative survival of patients with advanced gastric cancer(AGC). METHODS 650 patients with AGC from two centers (290 cases from the First Affiliated Hospital of Dalian University and 360 points from the Fujian Medical University Union Hospital) were selected as the study subjects based on unified screening criteria. Clinical data, preoperative abdominal CT images, results of hematology-related examinations, tumor-related characteristics, and surgical and follow-up data of the patients were collected and organized. The L3 vertebral level muscle area was measured using computer-assisted measurement techniques, and the skeletal muscle index(SMI) was calculated based on this measurement. The prognostic nutrition index (PNI) was calculated based on serum albumin and lymphocyte count indicators. The Kaplan-Meier survival analysis of data from the First Affiliated Hospital was used to determine that SMI and PNI are significantly correlated with the postoperative survival rate of patients with advanced gastric cancer. Based on this, a novel combined index smni was fitted and stratified for risk. Cox proportional hazards regression analysis was used to determine that the index smni is an independent prognostic risk factor for patients with AGC after surgery. The ROC curve was used to describe the predictive ability of the new combined index and its importance and predictive power in predicting postoperative survival of patients with AGC, which was verified in the data of Fujian Medical University Union Hospital. RESULT The Kaplan-Meier curve analysis of the combined indicator smni Is clearly associated with long-term survival(3-year OS (P < 0.001) and DSS (P < 0.001)), univariate analysis and multivariate analysis showed that smni was an independent prognostic risk factor, The ROC curve for the first center 3-year OS(AUC = 0.678), DSS(AUC = 0.662) show good predictive ability and were validated in the second center. CONCLUSION The combined index smni has a good predictive ability for the postoperative survival rate of patients with AGC and is expected to provide a new reference basis and more accurate and scientific guidance for the postoperative management and treatment of patients with AGC.

Sci Rep 2023; 13:10116. [PMID: 37344511 DOI: 10.1038/s41598-023-36968-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2023] [Accepted: 06/13/2023] [Indexed: 06/23/2023] Open
Abstract
The obesity paradox is reported to exist in various diseases. However, obesity is a pivotal issue in gastric cancer (GC) patients because of the surgical difficulty related to postoperative abdominal infectious complications (PAIC). This study clarified the existence of the obesity paradox in GC. Between 1997 and 2015, 1536 consecutive patients underwent curative gastrectomy. Of all patients, 18.6% (285/1536) were obese and tended to have a better prognosis (P = 0.073). In patients without PAIC, obesity was a significant prognostic factor for 5-year overall survival (P = 0.017). PAIC was an independent poor prognostic factor in both obese and non-obese patients (P < 0.001; hazard ratio [HR] 4.22 and 1.82). In pStage II-III patients, there was a large and significant prognostic difference between non-PAIC and PAIC obese patients (P = 0.006; 5-year overall survival: 69.7% vs. 43.8%) related to the higher incidence of peritoneal recurrence in PAIC obese patients (P = 0.035; 31% vs. 10%). Whereas, there was a small prognostic difference between non-PAIC and PAIC non-obese patients (P = 0.102; 5-year overall survival: 56.5% vs. 51.9%). Although the obesity paradox is present in GC, PAIC had a more negative prognostic impact through peritoneal recurrence in obese GC patients.

Variation in Body Mass and Skeletal Muscle Indices in Head and Neck Cancer Patients Undergoing (Chemo)Radiotherapy and Nutritional Intervention. Curr Oncol 2022; 30:250-260. [PMID: 36661669 PMCID: PMC9857332 DOI: 10.3390/curroncol30010020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2022] [Revised: 12/16/2022] [Accepted: 12/22/2022] [Indexed: 12/28/2022] Open
Abstract
The aim of this study was to analyze variation in body mass index (BMI) and skeletal muscle index (SMI) in head and neck squamous cell carcinoma (HNSCC) patients who underwent exclusive radiotherapy (RT) or concurrent chemo-radiotherapy (RT-CHT). We enrolled 73 HNSCC pts treated with definitive or post-operative RT (14 pts) or RT-CHT (59 pts). At the time of diagnosis (t0) and 3 months after treatment completion (t3), CT scans were retrieved to measure skeletal muscle at the level of the C3 vertebra. Median follow-up was 16 months. Nine disease progressions with distant metastases and eleven local relapses were observed. Fifty-three pts were free from progression at 1 year. At t0, average BMI was 25.8 (SD 4.1), while at t3 it was 24.5, with no reduction in 54 pts. A BMI decrease of −1.3 (p-value < 0.0001) between t0 and t3 was found with the Wilcoxon signed-rank test. SMI was 57.1 and 59.2 at t0 and t3, respectively (p-value = 0.005). According to our analysis, SMI variation seems to reflect the effect of an appropriate nutritional intervention and may represent a reliable, simple tool for muscle mass analysis.

Abstract
The prognosis of early gastric cancer (EGC) with submucosal invasion is favorable; however, several cases of recurrence have been reported even after curative gastrectomy. This study aimed to investigate risk factors and evaluate the clinical significance of the number of retrieved lymph nodes (LNs) in EGC with submucosal invasion. We retrospectively analyzed the data of 443 patients with gastric cancer with submucosal invasion after curative gastrectomy for recurrent risk factors. Recurrence was observed in 22 of the 443 gastric cancer patients with submucosal invasion. In the univariate analysis, the risk factors for recurrence were the number of retrieved LNs ≤ 25 and node metastasis. In the multivariate analysis, retrieved LNs ≤ 25 (hazard ratio [HR] = 5.754, P-value = .001) and node metastasis (HR = 3.031, P-value = .029) were independent risk factors for recurrence after curative gastrectomy. Body mass index was related to retrieved LNs ≤ 25 in univariate and multivariate analyses (HR = .510, P = .002). The number of retrieved LNs and node metastases were independent risk factors for EGC with submucosal invasion. For EGC with submucosal invasion, retrieved LNs > 25 are necessary for appropriate diagnosis and treatment.

Preoperative High Visceral Fat Increases Severe Complications but Improves Long-Term Prognosis after Gastrectomy for Patients with Advanced Gastric Cancer: A Propensity Score Matching Analysis.

Abstract
This study investigated the paradox of high visceral fat mass increasing severe complications but improving long-term prognosis after radical gastrectomy for gastric cancer. This was a retrospective cohort study of consecutive patients with primary stage I–III gastric cancer who underwent gastrectomy between April 2008 and June 2018. The visceral adipose tissue index (VAI) was calculated by dividing the visceral fat mass preoperatively measured on computed tomography by the square of the height. Patients with VAIs below the median cut-off value were classified as low-VAI, while those above it were classified as high-VAI. We compared the postoperative complication rate and overall survival (OS) in the low- and high-VAI groups after adjusting patient characteristics using propensity score matching (PSM). There were 155 patients in both groups after PSM. After matching, there was no significant difference in factors other than BMI and VAI that were not adjusted. The high-VAI group had more severe postoperative complications (p = 0.018), but the OS was significantly better in the high-VAI group (hazard ratio 0.611, 95%CI 0.403–0.928, p = 0.021). Preoperative high visceral fat mass not only increased severe complications, but also improved OS after gastrectomy in patients with advanced gastric cancer.

Abstract
Excess body weight is a significant risk factor for the development and recurrence of many types of cancer. Patients with a history or current diagnosis of cancer who are overweight or have obesity have an increased risk of cancer treatment-related morbidity, recurrence, and decreased quality of life. Weight loss and maintenance of a healthy body weight may reduce cancer morbidity and recurrence in cancer survivors. While guidelines for cancer survivorship elaborate sufficiently on lifestyle interventions, little guidance is provided when considering additional therapies like anti-obesity pharmacotherapy or bariatric surgery for weight loss. This review will highlight and address current recommendations and feasible interventions that clinicians may consider to further reduce the incidence and recurrence of cancer in patients with obesity.

Abstract
BACKGROUND Obesity can hinder laparoscopic procedures and impede oncological safety during laparoscopic cancer surgery. Deep neuromuscular block (NMB) reportedly improves laparoscopic surgical conditions, but its oncological benefits are unclear. We aimed to evaluate whether deep NMB improves the oncologic quality of laparoscopic cancer surgery in obese patients. STUDY DESIGN We conducted a double-blinded, parallel-group, randomized, phase 3 trial at 9 institutions in Korea. Clinical stage I and II gastric cancer patients with a BMI at or above 25 kg m -2 were eligible and randomized 1:1 ratio to the deep or moderate NMB groups, with continuous infusion of rocuronium (0.5-1.0 and 0.1-0.5 mg kg -1 h -1, respectively). The primary endpoint was the number of retrieved lymph nodes (LNs). The secondary endpoints included the surgeon's surgical rating score (SRS) and interrupted events. RESULTS Between August 2017 and July 2020, 196 patients were enrolled. Fifteen patients were excluded, and 181 patients were finally included in the study. There was no significant difference in the number of retrieved LNs between the deep (N = 88) and moderate NMB groups (N = 93; 44.6 ± 17.5 vs 41.5 ± 16.9, p = 0.239). However, deep NMB enabled retrieving more LNs in patients with a BMI at or above 28 kg/m2 than moderate NMB (49.2 ± 18.6 vs 39.2 ± 13.3, p = 0.026). Interrupted events during surgery were lower in the deep NMB group than in the moderate NMB group (21.6% vs 36.6%; p = 0.034). The SRS was not influenced by NMB depth. CONCLUSION Deep NMB provides potential oncologic benefits by retrieving more LNs in patients with BMI at or above 28 kg/m2 during laparoscopic gastrectomy.

Abstract
Background A variety of factors for short‐ and long‐term outcomes have been reported after radical resection for gastric cancer (GC). Obesity and emaciation had been reported to be a cause of poor short‐ and long‐term outcomes with gastrointestinal cancer. However, the indicators are still controversial. The purpose of this study was to evaluate the relationship between perirenal thickness (PT) and short‐ and long‐term outcomes after radical surgery for GC. Methods We analyzed the data of 364 patients with GC who underwent radical surgery. We evaluated the distance from the anterior margin of the quadratus lumborum muscle to the dorsal margin of the left renal pole using computed tomography (CT) as an indicator of PT. The association between PT and clinicopathological factors and short‐ and long‐term outcomes was evaluated. Results The PT data were divided into low, normal, and high groups by gender using the tertile value. We found that the PT low group was 121 patients, normal group was 121 patients, and high group was 122 patients. Multivariate analyses showed that the high PT group was an independent risk factor for a short‐outcome after curative surgery in GC patients (odds ratio 2.163; 95% confidence interval [CI] 1.156–4.046; P = .016). And the low PT group was an independent risk factor for overall survival (hazard ratio 2.488; 95% CI 1.400–4.421; P = .0019) and relapse‐free survival (hazard ratio 2.342; 95% CI 1.349–4.064; P = .0025) after curative surgery in GC patients. Conclusion Perirenal thickness is a simple and useful factor for predicting short‐ and long‐term outcomes after radical surgery for GC.

Abstract
BACKGROUND Preoperative malnutrition is believed to contribute to increased postoperative complications. Preoperative serum prealbumin level was reported to be a predictor of nutritional status and postoperative complications after gastrointestinal surgery, including gastrectomy. Gastric outlet obstruction caused by gastric cancer leads to insufficient nutritional status. However, the impact of preoperative enteral nutrition using naso-jejunal feeding tubes for patients with gastric outlet obstruction is not fully understood. METHODS From July 2010 to June 2020, 50 patients with gastric cancer-induced outlet obstruction who underwent gastrectomy following preoperative enteral nutrition via feeding tube were included. We investigated the relationship between changes in nutritional status after preoperative enteral nutrition and postoperative complications. Postoperative complications were defined as grade ≥II based on the Clavien-Dindo classification. RESULTS The median period of preoperative enteral nutrition was 10 days. The median increase rate of the serum prealbumin level was 10.5% (interquartile range, 0.63-38.2%), and patients with an increase rate ≥ 10% were defined as the elevated group. Postoperative morbidity was significantly higher in the non-elevated group (P = 0.0031). Univariate and multivariate analyses showed that an increased rate of the serum prealbumin level was an independent risk factor of postoperative complications for patients with gastric outlet obstruction caused by gastric cancer (P = 0.0025 and P = 0.009, respectively). CONCLUSIONS Preoperative enteral nutrition improved the serum prealbumin level of patients with gastric cancer-induced outlet obstruction, and an increased rate of prealbumin can be an indicator of sufficient preoperative enteral nutrition and decreased postoperative morbidity.

Abstract
Objectives: Postoperative complications (PCs) in patients with gastrointestinal cancer (GIC) lead
to reduced lifespan and poor quality of life. The aim of this study was to investigate
the correlation between preoperative exercise-related factors, together with other
contributory factors, and the frequency of PCs in patients with GIC. Methods: This was a cross-sectional, three-institution study. We enrolled 299 patients who were
scheduled for elective surgery for GIC (182 men and 117 women; age, 65.7 ± 11.0 years).
PCs were graded using the Clavien–Dindo classification based on the medical records 1
month postoperatively. Exercise-related factors (the skeletal muscle index, the
isometric knee extension torque, and the 6-min walk test [6 MWT] distance) were measured
before surgery. Based on previous studies of factors contributing to complications, data
on age, sex, clinical cancer stage, comorbidities, neoadjuvant therapy, type of surgery,
surgery duration, blood loss, blood transfusion, laboratory data, respiratory function,
body mass index, and visceral fat area were collected. Results: The frequency of PCs was positively correlated with surgery duration (β=0.427) and
C-reactive protein (CRP) level on postoperative day 3 (β=0.189). The 6 MWT was
negatively correlated with the frequency of PCs through CRP level on postoperative day 3
(β=–0.035). This model demonstrated an acceptable fit to the data (goodness-of-fit
index, 0.979; adjusted goodness-of-fit index, 0.936; comparative fit index, 0.944; and
root mean square error of approximation, 0.076). Conclusions: Preoperative walking capacity was correlated with PCs in patients undergoing GIC
surgery. Prevention of PCs in patients with GIC requires the monitoring of both surgical
parameters and postoperative inflammation.

Tao W, Cheng YX, Liu XY, Zhang B, Yuan C, Peng D, Zhang W. A Simple Predictive Index of the Abdominal Shape for Postoperative Complications After Laparoscopy-Assisted Distal Gastrectomy for Gastric Cancer. Front Surg 2021; 8:768434. [PMID: 34957204 PMCID: PMC8692270 DOI: 10.3389/fsurg.2021.768434] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2021] [Accepted: 11/15/2021] [Indexed: 12/24/2022] Open
Abstract
Background: The purpose of this study was to explore the effect of abdominal shape on the short-term surgical outcomes. Methods: This was a retrospective study that included 425 patients undergoing laparoscopic distal gastrectomy plus D2 lymph node dissection (LADG) from January 2013 to January 2021. The abdominal parameters, including the shortest distance of the pancreas from the anterior abdominal skin (PAAD), the lower sternum angle (LSA), the thickness of the subcutaneous fat at the navel level (SFT), the anteroposterior diameters (APD) and the left-right diameters (LRD) at the navel level, the distance from the xiphoid process to the navel (XND) and the distance from the xiphoid process to the pubis (XBD), were calculated by preoperative abdominal computed tomography (CT) imaging. The parameters and short-term surgical outcomes were analyzed. Results: In males, the number of retrieved lymph nodes was significantly higher in patients with a lower APD group (p = 0.031). The operation time was significantly shorter in the lower body mass index (BMI) (p = 0.007), lower LSA (p = 0.035), lower PAAD (p = 0.000), lower SFT (p = 0.004), lower APD (p = 0.000) and lower LRD (p = 0.014) groups. The estimated blood loss was significantly less in the lower BMI (p = 0.035), lower LSA (p = 0.001), lower PAAD (p = 0.012), lower SFT (p = 0.003), lower APD (p = 0.000) and lower LRD (p = 0.005) groups. The complications were fewer in the lower LSA (p = 0.012), lower APD (p = 0.043) and lower LRD (p = 0.023) groups. In females, the postoperative hospital stay was shorter in the lower PAAD (p = 0.027) and lower SFT (p = 0.004) groups, and the lower SFT group had fewer complications (p = 0.020). Furthermore, in multivariate analysis, higher PAAD (p = 0.037, odds ratio = 1.030, 95% CI = 1.002-1.059) was an independent factor for predicting postoperative complications in males. Conclusion: Various abdominal shapes can affect the difficulty of LADG. Higher PAAD is a simple independent index for predicting postoperative complications in males.

A systematic review and meta-analysis. Am J Surg 2021; 223:884-892. [PMID: 34627600 DOI: 10.1016/j.amjsurg.2021.09.024] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2021] [Revised: 07/24/2021] [Accepted: 09/23/2021] [Indexed: 12/27/2022]
Abstract
BACKGROUND To assess which anastomosis technique is the most appropriate after laparoscopic total gastrectomy, a systematic review with meta-analysis has been performed to evaluate safety and efficacy of the linear versus circular stapler performing the oesophagojejunostomy. METHODS A systematic search was performed using the string: total AND gastrectomy AND (circular OR linear OR stapler). Extracted data were patients' number, gender, age, BMI, ASA Score, tumor stage. Outcomes were leakages, stenoses and bleedings, number of overall anastomotic complications, mortality, operative time, time to first flatus and diet resumption and length of stay of each group. A meta-analysis among the included studies was performed. A subgroup analysis, including the studies in which the Authors considered a single technique to perform each type of anastomosis (LS and CS), was performed. Meta-regression analyses were performed to assess if one or more demographic and clinical variables significantly impacted on the obtained results. RESULTS 12 articles were included in the final analysis. A significant difference was observed in terms of "overall anastomotic complications" in favour of linear stapling (RD = 0.06, p = 0.01). No significant differences were observed in terms of postoperative complications anastomosis-related, even if a trend towards advantages of linear stapling have been found (stenosis: RD = 0.04, p = 0.06; bleeding: RD = 0.02, p = 0.05). However, all the study was retrospective and there was high heterogeneity among the studies. CONCLUSION Linear stapler seems to be related with lesser number of complication if compared with circular stapler. However, further high-quality studies are needed to obtain definitive conclusions.

Prognostic value of preoperative body mass index for diabetic patients with non-metastasis gastric cancer: a single center experience. BMC Surg 2021; 21:320. [PMID: 34372800 PMCID: PMC8351091 DOI: 10.1186/s12893-021-01316-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2020] [Accepted: 08/02/2021] [Indexed: 12/20/2022] Open
Abstract
Aim This study was designed to investigate the prognostic effect of preoperative body mass index (BMI) for Type 2 diabetes mellitus (T2DM) patients with non-metastasis gastric cancer (GC) who underwent D2 gastrectomy. Methods T2DM patients with pT1–4bN0–3bM0 GC were retrospectively collected in Department of Gastrointestinal Surgical Oncology, Fujian Cancer Hospital & Fujian Medical University Cancer Hospital from January, 2000 to December, 2010. These patients underwent D2 radical resection of the stomach combined with regional lymphadenectomy. Chi-square test was used to analyze unordered categorical variables and ranked data, followed by Kaplan–Meier analysis as well as Cox regression models to detect risk factors for survival outcomes. In addition, the cut-off point was determined by the X-tile program. All analyses were carried out using survival package of R and SPSS Software. Results A total of 302 T2DM patients with pT1–4bN0–3bM0 GC were collected and analyzed. The cut-off points of BMI, identified by the X-tile program, was 19 kg/m2. Patients with low BMI (< 19 kg/m2) had a higher percentage of advanced T stage (T4a and T4b), more advanced TNM stage (stage IIIA, IIIB and IIIC), and more elevated level of serum carcinoembryonic antigen (CEA), compared to those with high BMI (> 19 kg/m2) (all P < 0.05). In the low BMI subgroup, the 5-year overall survival rate was 39.02%, which was as high as 58.11% in the high BMI subgroup (P < 0.05). In the multivariate Cox regression model revealed that IIIC stage (OR = 3.101), N3b stage (OR = 3.113) were the most important prognostic indicators, followed by pretreatment BMI (OR = 2.136). Conclusion Low preoperative BMI (< 19 kg/m2) was a poor prognostic marker for T2DM patients with pT1–4bN0–3bM0 GC.

Abstract
Background Colorectal cancer (CRC) is one of the most common malignant tumors. Surgery is the primary treatment for CRC. Recent studies have shown that visceral-to-subcutaneous fat ratio (VSR) may be a potential indicator of risk. The aim of the present study was to determine whether VSR is a suitable predictor of the impact of postoperative complications in CRC. Material/Methods Clinical data from 129 patients were analyzed retrospectively. All patients underwent laparoscopic surgery for CRC. Preoperative imaging was used to quantify VSR. The primary outcome was 30-day postoperative complications. Multivariate logistic regression was used to determine the association between obesity indexes and postoperative complications. Results There were 129 patients who underwent primary resections of colorectal cancer. At 30 days after surgery, postoperative complications had occurred in 33 (25.6%) patients. VSR was significantly associated with postoperative complications in multivariate analysis (P=0.032, OR 6.103, 95% CI 1.173–31.748). In ROC analysis, VSR was a potential predictor of complications (AUC 0.650). A cutoff value of VSR ≥0.707 was associated with 60% sensitivity and 29% specificity for postoperative complications. Patients with VSR ≥0.707 had 41.7% risk of morbidity, whereas those with <0.707 had 16.0% risk (P=0.001). Conclusions Our study shows that VSR is superior to VFA for prediction of the risk of complications following CRC laparoscopic surgery. We have also identified the optimal cutoff values for the use of VSR for this purpose. Measurement of VSR and identifying patients with increased risk of postoperative complications facilitate making perioperative decisions.

Is Sarcopenic Obesity an Indicator of Poor Prognosis in Gastric Cancer Surgery? A Cohort Study in a Western Population. J Gastrointest Surg 2021; 25:1388-1403. [PMID: 32661833 DOI: 10.1007/s11605-020-04716-1] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2019] [Accepted: 06/23/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND The prognostic value of sarcopenic obesity in gastric cancer surgery remains debated. We aimed to evaluate the impact on outcomes of body composition and sarcopenic obesity after gastrectomy for gastric cancer. METHODS A retrospective review of prospectively maintained database of patients undergoing gastrectomy for gastric cancer from 2010 to 2017 was performed. Skeletal muscle mass and visceral adipose tissue were evaluated by preoperative computed tomography to define sarcopenia and obesity. Patients were classified in body composition groups according to the presence or absence of sarcopenia and obesity. Prognostic factors for survival were assessed by multivariate Cox analysis. RESULTS Of the 198 patients undergoing gastrectomy for gastric cancer, 90 (45.4%) patients were sarcopenic, 130 (67.7%) obese, and in the subclassification for body composition categories: 33 (17%) nonsarcopenic nonobesity, 75 (38%) non sarcopenic obesity, 35 (17%) sarcopenic nonobesity, and 55 (28%) sarcopenic obesity. No category of body composition was a predictor of postoperative complications and worse overall and disease-free survival outcomes. Multivariable analysis identified ASA III classification, preoperative weight loss > 10%, postoperative surgical re-intervention, and advanced tumor stage as independent prognostic factors for overall survival, and patients aged 75 years or older, preoperative weight loss > 10%, elevated netrophil-lymphocyte ratio, and advanced tumor stage as independent prognostic factors for disease-free survival. CONCLUSIONS Sarcopenia, obesity, and sarcopenic obesity were not associated with worse outcomes after gastric cancer surgery.

Abstract
PURPOSE This study aimed to clarify the relationship between obesity and postoperative C-reactive protein (CRP) and assess the usefulness of obesity status-adjusted CRP levels for predicting early complications following laparoscopic gastrectomy for gastric cancer. METHODS This study retrospectively analyzed 527 patients who underwent laparoscopic gastrectomy for gastric cancer between January 2013 and March 2019. Patients were classified into three groups according to body mass index (BMI): BMI < 20; BMI ≥ 20 to < 25; and BMI ≥ 25. The correlation between BMI and perioperative CRP was investigated in 447 patients, excluding 80 with postoperative complications. The optimal CRP cutoff value of Clavien-Dindo (CD) grade ≥ 3 for predicting severe complications for each group was determined. RESULTS BMI was significantly correlated with CRP on postoperative day (POD) 3 (p < 0.001) in 447 patients without complications. According to the receiver operating characteristic curve analysis, CRP cutoff values on POD 3 for predicting severe complications were 92.4, 111.1, and 171.9 in the BMI < 20, BMI ≥ 20 to < 25, and BMI ≥ 25 groups, respectively. In multivariate analysis for CD grade ≥ 3 complications, cardiac history and POD 3 CRP levels higher than the adjusted cutoff were identified as independent factors significantly associated with severe complications (p = 0.021 and 0.015, respectively). CONCLUSION CRP cutoff values on POD 3 adjusted for BMI were useful for predicting severe complications in gastrectomy for gastric cancer.

Abstract
The impact of body mass index (BMI) on surgical outcomes has previously been studied in relation to several oncological procedures. Regarding gastric cancer surgery, published results have been contradicting in terms of degree of technical difficulty, risk of postoperative complications and survival. In an attempt to clarify these issues, we performed a meta-analysis to evaluate the impact of obesity (defined as BMI ≥ 30 kg/m2) on outcomes after gastrectomy for gastric cancer. The meta-analysis was performed according to the PRISMA guidelines. Eligible studies were identified through search of PubMed, EMBASE, Web of Science and Cochrane Library databases. Quality assessment was performed using the Newcastle-Ottawa scale. The meta-analysis was conducted using random-effects modeling. A total of 11 studies with 13 538 patients were eligible for analysis. Obesity was associated with a significantly longer operation time (WMD = 19.38 min, 95% CI 12.72-26.04; p < 0.001), increased risk of overall complications (RR = 1.23, 95% CI 1.06-1.42; p = 0.005) and pulmonary complications (RR = 3.81, 95% CI 2.24-6.46; p < 0.001). These findings remained irrespective type of surgery (laparoscopic vs. open) and type of gastrectomy. No differences were found regarding blood loss, number of resected lymph nodes, anastomotic leakage, hospital stay, 30-day mortality and 5-year overall survival. The conclusion of the current meta-analysis is that high BMI in gastric cancer patients is associated with longer operative time and more frequent overall postoperative complications. However, it has no negative impact on survival, indicating that gastrectomy is a safe procedure for this group of patients.

Abstract
BACKGROUND How obesity has an impact on operative and oncologic outcomes for gastric cancer patients is unclear, and the influence of obesity on response to neoadjuvant chemotherapy (NAC) has not been evaluated. METHODS Patients who underwent curative gastrectomy for primary gastric cancer between 2000 and 2018 were retrospectively identified. After stratification for NAC, operative morbidity, mortality, overall survival (OS), and disease-specific survival (DSS) were compared among three body mass index (BMI) categories: normal BMI (< 25 kg/m2), mild obesity (25-35 kg/m2), and severe obesity (≥ 35 kg/m2). RESULTS During the study period, 984 patients underwent upfront surgery, and 484 patients received NAC. Tumor stage did not differ among the BMI groups. However, the rates of pathologic response to NAC were significantly lower for the patients with severe obesity (10% vs 40%; p < 0.001). Overall complications were more frequent among the obese patients (44.3% for obese vs 24.9% for normal BMI, p < 0.001). Intraabdominal infections were also more frequent in obese patients (13.9% for obese vs 4.7% for normal BMI, p = 0.001). In the upfront surgery cohort, according to the BMI, OS and DSS did not differ, whereas in the NAC cohort, severe obesity was independently associated with worse OS [hazard ratio (HR) 1.87; 95% confidence interval (CI) 1.01-3.48; p = 0.047] and disease-specific survival (DSS) (HR 2.08; 95% CI 1.07-4.05; p = 0.031). CONCLUSION For the gastric cancer patients undergoing curative gastrectomy, obesity was associated with significantly lower rates of pathologic response to NAC and more postoperative complications, as well as shorter OS and DSS for the patients receiving NAC.

Abstract
PURPOSE This study aimed to examine the impact of preoperative body mass index (BMI) on postoperative activities of daily living (ADL) and clinical outcomes in older patients who underwent curative gastrectomy. METHODS This was a retrospective observational study using a nationwide inpatient database in Japan. The study included 1769 patients with gastric cancer, aged ≥ 65 years old, who underwent gastrectomy. BMI was defined as per the World Health Organization classifications for Asian populations. Primary outcome was ADL at discharge, assessed by Barthel index. Secondary outcomes included postoperative complications and length of hospital stay. RESULTS Patients analyzed included 890 (50.3%) aged 65-74 years, 745 (42.1%) aged 75-84 years, and 134 (7.6%) aged ≥ 85 years; 71.5% were male. According to BMI classification, 11.9% patients were considered underweight (< 18.5 kg/m2), 46.7% were in the standard range (18.5 to < 23 kg/m2), 34.1% were classified as overweight (23-27.5 kg/m2), and 7.3% were in the obese group (≥ 27.5 kg/m2). In multivariate analysis, a significant association was observed between BMI and Barthel index scores (underweight group: standardized coefficient, - 0.040; compared with standard group; p = 0.013), postoperative complication (obese group: odds ratio, 1.562; compared with standard group; p = 0.034), and length of hospital stay (obese group: standardized coefficient, 0.047; compared with standard group; p = 0.019). CONCLUSION Perioperative management with a focus on BMI is important in older patients undergoing elective curative gastrectomy.

A machine learning-based predictor for the identification of the recurrence of patients with gastric cancer after operation. Sci Rep 2021; 11:1571. [PMID: 33452440 PMCID: PMC7810757 DOI: 10.1038/s41598-021-81188-6] [Citation(s) in RCA: 22] [Impact Index Per Article: 7.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2020] [Accepted: 01/05/2021] [Indexed: 12/20/2022] Open
Abstract
To explore the predictive performance of machine learning on the recurrence of patients with gastric cancer after the operation. The available data is divided into two parts. In particular, the first part is used as a training set (such as 80% of the original data), and the second part is used as a test set (the remaining 20% of the data). And we use fivefold cross-validation. The weight of recurrence factors shows the top four factors are BMI, Operation time, WGT and age in order. In training group:among the 5 machine learning models, the accuracy of gbm was 0.891, followed by gbm algorithm was 0.876; The AUC values of the five machine learning algorithms are from high to low as forest (0.962), gbm (0.922), GradientBoosting (0.898), DecisionTree (0.790) and Logistic (0.748). And the precision of the forest is the highest 0.957, followed by the GradientBoosting algorithm (0.878). At the same time, in the test group is as follows: the highest accuracy of Logistic was 0.801, followed by forest algorithm and gbm; the AUC values of the five algorithms are forest (0.795), GradientBoosting (0.774), DecisionTree (0.773), Logistic (0.771) and gbm (0.771), from high to low. Among the five machine learning algorithms, the highest precision rate of Logistic is 1.000, followed by the gbm (0.487). Machine learning can predict the recurrence of gastric cancer patients after an operation. Besides, the first four factors affecting postoperative recurrence of gastric cancer were BMI, Operation time, WGT and age.

Abstract
Background: The goal of this study was to investigate the impact of different nutritional parameters in patients with esophageal squamous cell carcinoma (ESCC) who underwent surgical resection. Methods: A total of 620 patients with ESCC who underwent esophagectomy were analyzed. A receiver operating characteristic curve was constructed to set the appropriate cutoff points for five nutritional parameters: serum albumin (SA), body mass index (BMI), geriatric nutritional risk index (GNRI), prognostic nutritional index (PNI), and a new modified nutritional risk index (mNRI). Survival analyses were performed to calculate overall survival and investigate the independent prognostic factors. Results: The median preoperative BMI, SA, GNRI, PNI, and mNRI values were 20.90, 42.75, 102.95, 51.90, and 63.90, respectively. The corresponding optimal cutoff points were 18.75 for BMI, 43.05 for SA, 98.5 for GNRI, 51.45 for PNI, and 61.45 for mNRI. All nutritional parameters were significantly correlated with tumor length and pT category. Decreased nutritional parameters were significantly correlated with poor survival in univariate analysis; however, only the mNRI was an independent prognostic factor in multivariate analysis (P = 0.041). Conclusions: Nutritional parameters are convenient and valuable prognostic factors in ESCC patients who undergo surgical resection. The new mNRI parameter may be superior to the other nutritional parameters.

Abstract
Objective The systemic inflammation index and body mass index (BMI) are easily accessible markers that can predict mortality. However, the prognostic value of the combined use of these two markers remains unclear. The goal of this study was therefore to evaluate the association of these markers with outcomes based on a large cohort of patients with gastric cancer. Methods A total of 2,542 consecutive patients undergoing radical surgery for gastric or gastroesophageal junction adenocarcinoma between 2009 and 2014 were included. Systemic inflammation was quantified by the preoperative neutrophil-to-lymphocyte ratio (NLR). High systemic inflammation was defined as NLR ≥ 3, and underweight was defined as BMI < 18.5 kg/m2. Results Among 2,542 patients, NLR ≥ 3 and underweight were common [627 (25%) and 349 (14%), respectively]. In the entire cohort, NLR ≥ 3 or underweight independently predicted overall survival (OS) [hazard ratio (HR): 1.236, 95% confidence interval (95% CI): 1.069-1.430; and HR: 1.600, 95% CI: 1.350-1.897, respectively] and recurrence-free survival (RFS) (HR: 1.230, 95% CI: 1.054-1.434; and HR: 1.658, 95% CI: 1.389-1.979, respectively). Patients with both NLR ≥ 3 and underweight (vs. neither) had much worse OS (HR: 2.445, 95% CI: 1.853-3.225) and RFS (HR: 2.405, 95% CI: 1.802-3.209). Furthermore, we observed similar results in subgroup analyses according to pathological stage, age, and postoperative chemotherapy. Conclusions Our results showed that preoperative elevated NLR and decreased BMI had a significant negative effect on survival. Underweight combined with severe inflammation could enhance prognostication. Taking active therapeutic measures to reduce inflammation and increase nutrition may help improve outcomes.

Abstract
Among patients undergoing gastrectomy for gastric cancer, the impact of anthropometric indices on surgical outcomes is not well-established. The aim of this study was to evaluate the prognostic significance of the skeletal muscle index (SMI) and body mass index (BMI) on overall survival (OS) in patients with gastric cancer.A total of 305 patients who underwent curative gastrectomy for gastric adenocarcinoma between January 2005 and March 2008 were enrolled. Patients were classified into groups based on the SMI and BMI. The SMI was measured by preoperative abdominal computed tomography (CT). The SMI groups were classified based on gender-specific cut-off values obtained by means of optimum stratification. BMI groups were divided according to the World Health Organization definition of obesity for Asians.The mean SMI was 58.2 cm/m and the mean BMI was 23.2 kg/m. One hundred fifteen (37.7%) patients had sarcopenia based on the diagnostic cut-off values (56.2 cm/m for men and 53.6 cm/m for women). Apart from gender, there were no significant differences in patient characteristics or surgical outcomes between the SMI groups. In the underweight group, tumor (T) stage, tumor-node-metastasis (TNM) stage, number of retrieved lymph nodes, D2 dissection, and hospital stay were significantly increased compared with the overweight/obese group. High and low BMI, and low SMI, were independent prognostic factors for OS (hazard ratio [HR] = 2.355, 1.736, and 1.607, respectively; P = .009, .023, and .033, respectively).SMI and BMI did not impact perioperative morbidity in patients undergoing gastrectomy for gastric cancer. Both SMI and BMI are useful prognostic factors for OS in gastric cancer patients after gastrectomy.

Abstract
Background Laparoscopic distal gastrectomy is used widely in surgery for gastric cancer. Excess visceral fat can limit the ability to dissect the suprapancreatic region, potentially increasing the risk of local complications, particularly pancreatic fistula. This study evaluated perirenal fat thickness as a surrogate for visceral fat to see whether this was related to complications after laparoscopic distal gastrectomy. Methods Perirenal fat thickness was measured dorsal to the left kidney as an indicator of visceral fat in patients with gastric cancer who underwent laparoscopic distal gastrectomy. Patients were divided into two groups: those with and those without complications. The relationship between perirenal fat thickness and postoperative complications was evaluated. Results The optimal cut‐off value for predicting morbidity using adipose tissue thickness was 10·7 mm; a distance equal to or greater than this was considered a positive perirenal fat thickness sign (PTS). A positive PTS showed a significant correlation with visceral fat area. Multivariable analysis found that a positive PTS was an independent risk factor for complications (hazard ratio 4·42, 95 per cent c.i. 2·31 to 8·86; P < 0·001). Conclusion Perirenal fat thickness as an indicator of visceral fat was an independent predictor of postoperative complications after laparoscopic distal gastrectomy for gastric cancer.

Abstract
Introduction: The effect of obesity on response to neoadjuvant chemotherapy (NACT) remains unknown. We aimed to investigate the effect of obesity on response to NACT and survival in locally-advanced gastric cancer (GC). Methods: From 2010 to 2019, 142 GC patients with clinical stage III disease who underwent curative surgery after NACT were enrolled. Patients were divided into 3 groups according to body mass index (BMI) as follows; BMI < 25 kg/m2, BMI = 25-30 kg/m2, and BMI > 30 kg/m2. The Mandard tumor regression grading system was used for tumor regression grade (TRG). Results: Of the 142 GC patients, 45(31.7%) were female. The median age was 58 years. BMI was < 25 kg/m2 in 60 (42.3%) patients, 25-30 kg/m2 in 44 (31%) patients, and > 30kg/m2 in 38 (26.8%) patients. The numbers of patients with TRGI-II, TRGIII, and TRGIV-V were 35 (24.6%), 44 (31%), and 63 (44.4%), respectively. There was no statistically significant difference among BMI groups in terms of disease-free survival (DFS) and overall survival (OS) (p = 0.919 and p = 0.398, respectively). According to TRG groups; mDFS was 46 months in TRG I-II, 28 months in TRG III, and 18 months in TRG IV-V (p<0.001). In multivariate analysis, presence of perineural invasion and lymphovascular invasion were the factors affecting TRG. Conclusion: In our study, we found that pre-treatment obesity did not affect the TRG in clinical stage III GC patients. However, a better TRG status was associated with improved survival.

Abstract
The aim of this study was to analyse the effect of body mass index (BMI), both low and high values, on the perioperative complication rate in patients with oral squamous cell carcinoma (OSCC). The medical records of 259 patients operated between 2014 and 2017 for OSCC were reviewed. Univariate and multivariate analyses were performed. Sixty of the 259 patients developed 87 complications. Low or high BMI was not associated with the perioperative complication rate. A longer operating time and increased blood loss were associated with a higher perioperative complication rate and higher Clavien-Dindo grade. Low BMI, American Society of Anesthesiologists score 2 and 3, a longer operating time, and increased blood loss were associated with a longer hospital stay. Low BMI was associated with a longer hospital stay. Neither low nor high BMI was associated with the perioperative complication rate. A longer operating time and increased blood loss were associated with a higher perioperative complication rate and higher Clavien-Dindo grade.

Abstract
Gastrectomy is considered the gold standard treatment for gastric cancer patients. Currently, there are two minimally invasive surgical methods to choose from, robotic gastrectomy (RG) and laparoscopic gastrectomy (LG). Nevertheless, it is still unclear which is superior between the two. This meta-analysis aimed to investigate the effectiveness and safety of RG and LG for gastric cancer. A systematic literature search was performed using PubMed, Embase, and the Cochrane Library databases until September 2018 in studies that compared RG and LG in gastric cancer patients. Operative and postoperative outcomes analyzed were assessed. The quality of the evidence was rated using the Grading of Recommendations, Assessment, Development and Evaluations. Twenty-four English studies were analyzed. The meta-analysis revealed that the RG group had a significantly longer operation time, lower intraoperative blood loss, and higher perioperative costs compared to the LG group. However, there were no differences in complications, conversion rate, reoperation rate, mortality, number of lymph nodes harvested, days of first flatus, postoperative hospitalization time, and survival rate between the two groups. RG was shown to be associated with decreased intraoperative blood loss and increased perioperative cost and operation time compared to LG. Several higher-quality original studies and prospective clinical trials are required to confirm the advantages of RG.

Abstract
Obesity is a major health issue in the modern world population and a risk factor for surgical procedures. This study examined perioperative and oncologic results of gastrectomy in obese patients diagnosed with gastric cancer. BMI ≥30 kg/m2 was used to designate obesity. Five hundred and one patients were operated throughout the study period (2009–2018). The outcomes in obese patients (n = 205) were compared with those with normal weight (n = 171) and overweight (n = 125). The mean BMI was significantly different between the groups: 21.9 versus 26.7 versus 33.3 kg/m2 ( P < 0.01), respectively. Obesity was associated with higher incidence of comorbidities, longer operative time, and increased blood loss. Postoperative and short-term oncologic outcomes were similar. Median follow-up was 24 months with similar recurrence rates in the three groups. Median survival was comparable between the normal weight, overweight, and obese patients—36 (27–45) versus 42 (30–53) versus 32 (17–47) months, respectively ( P = 0.63). Obesity itself does not deteriorate the surgical outcomes of gastrectomy in patients with gastric cancer. Although technically demanding in obese patients, adequate lymph node yield and satisfactory long-term oncologic outcomes can be achieved in this group.

BMI-adjusted prognosis of signet ring cell carcinoma in patients undergoing radical gastrectomy for gastric adenocarcinoma. Asian J Surg 2020; 44:116-122. [PMID: 32467008 DOI: 10.1016/j.asjsur.2020.03.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2019] [Revised: 02/22/2020] [Accepted: 03/31/2020] [Indexed: 10/24/2022] Open
Abstract
BACKGROUND Compared with other histologic types, signet ring cell gastric carcinoma (SRC) has unique oncological characteristics, and its implication on the prognosis of gastric cancer patients remains unclear. The purpose of this study was to evaluate the prognostic impact of body mass index (BMI) on SRC patients. METHODS A retrospective analysis was performed using the clinical records of 3342 patients with SRC or tubular adenocarcinoma who underwent radical gastrectomy between 2000 and 2014. Patients were divided into three groups according to histologic subtype: SRC, well-to-moderately differentiated adenocarcinoma (WMD), and poorly differentiated adenocarcinoma (PD). We compared the survival of SRC patients with that of tubular adenocarcinoma patients according to BMI. RESULTS The 5-year survival of SRC was significantly worse than that of WMD (P < 0.001) but superior to that of PD (P < 0.001). BMI-stratified analysis showed that in the high-BMI group, the prognosis of SRC was similar to that of WMD (P > 0.05) and better than that of PD (P < 0.001). In normal-BMI patients, SRC had a worse prognosis than WMD (P < 0.001) but a more favorable prognosis than PD (P < 0.001). SRC among low-BMI patients displayed much poorer survival than did both WMD (P < 0.001) and PD (P = 0.005). Multivariate analysis indicated that the risk of death was the lowest in SRC patients with a high BMI and highest for SRC patients with a low BMI (low-BMI hazard ratio: SRC 1 vs. WMD 0.51 and PD 0.53). CONCLUSION SRC has worse prognostic impact as BMI decreases. BMI leads to differing prognosis of SRC compared with tubular adenocarcinoma.

World J Gastroenterol 2020; 26:1613-1627. [PMID: 32327910 PMCID: PMC7167420 DOI: 10.3748/wjg.v26.i14.1613] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/19/2019] [Revised: 03/05/2020] [Accepted: 03/19/2020] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Lifestyle factors such as body mass index (BMI), alcohol drinking, and cigarette smoking, are likely to impact the prognosis of gastric cancer, but the evidence has been inconsistent.
AIM To investigate the association of lifestyle factors and long-term prognosis of gastric cancer patients in the China National Cancer Center.
METHODS Patients with gastric cancer were identified from the China National Cancer Center Gastric Cancer Database 1998-2018. Survival analysis was performed via Kaplan-Meier estimates and Cox proportional hazards models.
RESULTS In this study, we reviewed 18441 cases of gastric cancer. Individuals who were overweight or obese were associated with a positive smoking and drinking history (P = 0.002 and P < 0.001, respectively). Current smokers were more likely to be current alcohol drinkers (61.3% vs 10.1% vs 43.2% for current, never, and former smokers, respectively, P < 0.001). Multivariable results indicated that BMI at diagnosis had no significant effect on prognosis. In gastrectomy patients, factors independently associated with poor survival included older age (HR = 1.20, 95%CI: 1.05-1.38, P = 0.001), any weight loss (P < 0.001), smoking history of more than 30 years (HR = 1.14, 95%CI: 1.04-1.24, P = 0.004), and increasing pTNM stage (P < 0.001).
CONCLUSION In conclusion, our results contribute to a better understanding of lifestyle factors on the overall burden of gastric cancer and long-term prognosis. In these patients, weight loss (both in the 0 to 10% and > 10% groups) but not BMI at diagnosis was related to survival outcomes. With regard to other factors, smoking history of more than 30 years conferred a worse prognosis only in patients who underwent gastrectomy. Extensive efforts are needed to elucidate mechanisms targeting the complex effects of lifestyle factors.

Abstract
Malnutrition is a critical problem in patients with gastric cancer (GC); however, no universally accepted marker that is convenient for clinical use has been defined. Recently, body composition has attracted considerable attention as a means to assess nutrition status in patients with cancer. The clinical role of skeletal muscle mass has also been increasingly recognized. In patients with GC, sarcopenia, which is the loss of skeletal muscle mass, was found to be significantly associated with increased post-surgical complications including hospital stay, healthcare costs, and poor survival. In addition, sarcopenic obesity, which combines the health risks of obesity and sarcopenia, is recognized as a strong risk factor for poor short- and long-term outcomes following gastrectomy. The mechanism linking sarcopenia to worse postoperative outcomes remains unclear; however, skeletal muscle has been found to act as an endocrine organ that produces substances affecting the immune system. In addition, sarcopenia was reported to be associated with toxicity and termination of chemotherapy. Patients with sarcopenia may be unable to react appropriately to the stress of gastrectomy and perioperative chemotherapy. To improve the short- and long-term outcomes of patients with GC and sarcopenia, adequate energy and protein intake are necessary during resistance training. In the present study, we performed a literature review and presented a method to evaluate body composition, the relationship between skeletal muscle mass and GC, and perioperative nutrition and exercise therapy for patients with sarcopenia.

A Modified ypTNM Staging System-Development and External Validation of a Nomogram Predicting the Overall Survival of Gastric Cancer Patients Received Neoadjuvant Chemotherapy. Cancer Manag Res 2020; 12:2047-2055. [PMID: 32256112 PMCID: PMC7090192 DOI: 10.2147/cmar.s236696] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2019] [Accepted: 02/21/2020] [Indexed: 12/15/2022] Open
Abstract
Purpose Neoadjuvant chemotherapy is now widely used in gastric cancer patients. However, the current 8th ypTNM staging system is developed based on patients with less extensive lymph node dissection and the predictive value is relatively limited. In this study, we aim to develop and validate a nomogram that predicts overall survival in gastric cancer patients received neoadjuvant chemotherapy. Patients and Methods From January, 2007 to December, 2014, 471 patients receiving neoadjuvant chemotherapy at our center were enrolled in the study. Based on the Cox proportional hazard model, a nomogram was developed from them and then an external validation was conducted on a cohort of 239 patients from another cancer center. Results The overall survival (OS) rates of 1 year and 3 years were 90.0% and 64.1%, respectively. Body mass index category, tumor location, T stage and N stage were independent prognostic factors for the survival outcome. The C-index of the model was 0.74 in the development cohort and 0.69 in the validation cohort. Our nomogram also showed good calibration in both cohorts. Conclusion We developed and validated a nomogram to predict the 1- and 3-year OS of patients who received neoadjuvant chemotherapy and radical gastrectomy with D2 lymph node dissection. This nomogram predicts survival more accurately than the AJCC TNM staging system, which is the current golden standard.

Abstract
INTRODUCTION Postoperative ileus occurs frequently following abdominal surgery. Identification of groups at high risk of developing ileus before surgery may allow targeted interventions. This review aimed to identify baseline risk factors for ileus. METHODS A systematic review was conducted with reference to PRISMA and MOOSE guidelines. It was registered on PROSPERO (CRD42017068697). Searches of MEDLINE, EMBASE and CENTRAL were undertaken. Studies reporting baseline risk factors for the development of postoperative ileus based on cohort or trial data and published in English were eligible for inclusion. Dual screening of abstracts and full texts was undertaken. Independent dual extraction was performed. Bias assessment was undertaken using the quality in prognostic studies tool. Meta-analysis using a random effects model was undertaken where two or more studies assessed the same variable. FINDINGS Searches identified 2,430 papers, of which 28 were included in qualitative analysis and 12 in quantitative analysis. Definitions and incidence of ileus varied between studies. No consistent significant effect was found for association between prior abdominal surgery, age, body mass index, medical comorbidities or smoking status. Male sex was associated with ileus on meta-analysis (odds ratio 1.12, 95% confidence interval 1.02-1.23), although this may reflect unmeasured factors. The literature shows inconsistent effects of baseline factors on the development of postoperative ileus. A large cohort study using consistent definitions of ileus and factors should be undertaken.

Abstract
BACKGROUND Obesity is generally considered to be associated with worse surgical outcome and impaired oncological prognosis. The impact of pre-therapeutic body mass index (BMI) in patients with oesophagogastric cancer on the surgical outcome is controversially discussed. METHODS We retrospectively examined 730 patients who had undergone curative treatment for oesophagogastric cancer at the Medical Center of the University of Freiburg (1996-2015). Patients were divided in groups according to pre-therapeutic BMI (underweight (UW): <18.5 kg/m2 ; normal weight (NW): 18.5-25 kg/m2 ; overweight (OW): 25-30 kg/m2 ; and obese (OB): >30 kg/m2 ). RESULTS Median BMI was 24.7 kg/m2 . Forty-two patients were UW, 337 NW, 263 OW and 84 OB. No significant differences between the groups (UW/NW/OW/OB) in operating time, hospital stay, perioperative complication rate and in-hospital mortality were found. Pre-therapeutic BMI was significantly associated with 5-year survival (UW: 22%, NW: 37%, OW: 51%, OB: 50%, P < 0.001). Multivariate analysis identified UW/NW (BMI <25 kg/m2 ) as an independent risk factor for poor survival (relative risk 1.38, P = 0.001) among high American Society of Anesthesiologists score, old age, positive resection margin and high cancer stage according to the Union Internationale Contre le Cancer (UICC). CONCLUSION In oesophagogastric cancer, OW and OB patients can be treated surgically without impaired perioperative outcome and expect improved long-term survival compared to patients with a BMI <25 kg/m2 .

Abstract
BACKGROUND Obesity has been reported to be a prognostic factor for many diseases in epidemiological studies; however, the results of studies examining the relationship between obesity and gastric cancer (GC) prognosis are inconsistent. METHODS A total of 460 patients with Stage II and III GC who underwent open R0 gastrectomy were included. Age, sex, body mass index (BMI classified into < 18.5, 18.5-25, and ≥ 25 kg/m2), stage, and postoperative adjuvant chemotherapy were analyzed to investigate the correlation with relapse-free survival (RFS). RESULTS Five-year RFS was 51% for the study patients. Five-year RFS values were 47.6%, 54.3%, and 40.1% for patients with BMI < 18.5, 18.5-25, and ≥ 25 kg/m2, respectively. The forest plot for relapse risk according to BMI showed a U shape. Multivariate analysis for RFS showed significant differences in stage and BMI; the hazard ratio for recurrence in patients with BMI ≥ 25 kg/m2 was 1.42 (95% confidence interval: 1.01-2.02, p = 0.0423) with reference to patients with BMI < 25 kg/m2. BMI ≥ 25.0 was associated with longer operation times, more blood loss, fewer lymph nodes dissected, more frequent postoperative surgical site infection, and intra-abdominal abscesses. CONCLUSIONS BMI ≥ 25 kg/m2 is an unfavorable prognostic factor for patients who underwent gastrectomy for Stage II and III GC.

Abstract
Background Malnutrition is a major risk factor for morbidity and mortality following gastrointestinal (GI) surgery. Nutritional Risk Index (NRI) and Body Mass Index (BMI) are the two well-validated tools that are readily available and do not add financial burden to the patients. The study aimed to analyze NRI and BMI as a preoperative nutritional indicator of postoperative complications following GI surgeries. Methods It is an observational study, where preoperative nutritional status and early postoperative complications <30 days (infectious or noninfectious) were studied. The patients admitted between July 2015 to May 2017, who underwent major GI surgeries were included in the study. The correlation between NRI and BMI of these patients were evaluated. Results The rate of wound infection was 4 (30.7%) out of 13 in severe malnutrition subgroup defined by NRI <83.5 which was found to be statistically significant (p = 0.003). However, it was not significant in a subgroup of patients with undernutrition defined by BMI <18.49%. In a subgroup analysis, abnormal NRI was found to be statistically significant (p = 0.004) in patients with malignant disease and malnutrition 64 (47.76%) out of 97 (72.3%). The mean NRI (94.49 ± 9.164) better correlated with advancing age (p < 0.05) and the correlation coefficient of 0.3100 showed a significant negative correlation. With 10 fold increase in age (r2 = 0.096) the likelihood of malnutrition was 9.6% and subsequently increased postoperative complications. Conclusion In cases of malignancy and advanced age, NRI is a better predictor of immediate postoperative outcome than BMI. Nutritional Risk Index (NRI) and Body mass Index (BMI) were used to screen the preoperative patients. NRI and BMI are the two well validated tools which is readily available and does not add financial burden to the patients. NRI better correlated with postoperative wound infections and the length of hospital stay. The patients with advanced age and malignant diseases were at higher risk of malnutrition and postoperative complications.

A homogenized approach to classify advanced gastric cancer patients with limited and adequate number of pathologically examined lymph nodes. Cancer Commun (Lond) 2019; 39:32.

Abstract
Background The prognosis of gastric cancer patients with a limited number of pathologically examined lymph nodes (eLN, < 16) is dismal compared to those with adequately eLN (≥ 16), yet they are still classified within the same subgroups using the American Joint Committee on Cancer (AJCC) staging system. We aimed at formulating an easy-to-adopt and clinically reliable stratification approach to homogenize the classification for these two categories of patients. Methods Patients staged according to the 8th AJCC pathological nodal (N) and tumor-node-metastasis (TNM) classification were stratified into a Limited and Adequate eLN cohort based on their number of pathologically examined LNs. The statistical differences between the 5-year overall survival (OS) rates of both cohorts were determined and based on which, patients from the Limited eLN cohort were re-classified to a proposed modified nodal (N′) and TNM (TN′M) classification, by matching their survival rates with those of the Adequate eLN cohort. The prognostic performance of the N′ and TN′M classification was then compared to a formulated lymph-node-ratio-based nodal classification, in addition to the 8th AJCC N and TNM classification. Results Significant heterogeneous differences in 5-year OS between patients from the Limited and Adequate eLN cohort of the same nodal subgroups were identified (all P < 0.001). However, no significant differences in 5-year OS were observed between the subgroups N0, N1, N2, and N3a of the Limited eLN cohort when compared with N1, N2, N3a, and N3b from the Adequate eLN cohort, respectively (P = 0.853, 0.476, 0.114, and 0.230, respectively). A novel approach was formulated in which only patients from the Limited eLN cohort were re-classified to one higher nodal subgroup, denoted as the N′ classification. This re-classification demonstrated superior stratifying and prognostic ability as compared to the 8th AJCC N and lymph-node-ratio classification (Akaike information criterion values [AIC]: 12,276 vs. 12,358 vs. 12,283, respectively). The TN′M classification also demonstrated superior prognostic ability as compared to the 8th AJCC TNM classification (AIC value: 12,252 vs. 12,312). Conclusion The proposed lymph node classification approach provides a clinically practical and reliable technique to homogeneously classify cohorts of gastric cancer patients with limited and adequate number of pathologically examined lymph nodes.

Asian J Surg 2019; 43:69-77. [PMID: 31036475 DOI: 10.1016/j.asjsur.2019.03.017] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2019] [Revised: 03/19/2019] [Accepted: 03/28/2019] [Indexed: 02/06/2023] Open
Abstract
The aim of this study was to evaluate the impact of high body mass index (BMI) on surgical outcome of laparoscopic gastrectomy for gastric cancer (GC). Systematic literature search was performed using PubMed and Embase databases. The relevant data were extracted, and surgical outcomes and postoperative complications were compared between BMI≥25 kg/m2 and BMI<25 kg/m2 group using a fixed effect model or random effect model. 16 studies, with a total of 9572 GC patients, were included in this meta-analysis. The results indicated that operation time was significantly longer (WMD:16.22, 95% CI: 14.10-18.34, P < 0.001; I2 = 0%) and the number of lymph nodes retrieved was significantly fewer (WMD:-2.11, 95%CI: -3.14, -1.07, P < 0.001; I2 = 64.0%) in high BMI patients than in other patients. In addition, the amount of intraoperative blood loss was significantly larger in high BMI patients (WMD: 23.43, 95%CI: 20.05-26.81, P < 0.001; I2 = 40.3%). Compared with non-high BMI patients, overweight and obese patients had a higher risk of postoperative complications (RR:1.26, 95%CI: 1.11-1.43, P < 0.001; I2 = 39.1%), especially for wound infection (RR:1.62, 95%CI: 1.15-2.29, P < 0.01; I2 = 18.8%) and postoperative ileus (RR:1.80, 95% CI: 1.05-3.09, P < 0.05; I2 = 0%). However, there was no significant difference between two patient groups for postoperative recovery, major surgery-related complications (eg: anastomotic leakage, pancreatic fistula and intra-abdominal bleeding) and postoperative mortality. Despite increased technical challenge and risk of postoperative complications, the majority of these complications may be minor and cured. Laparoscopic gastrectomy for GC was a feasible and safe procedure even for high BMI patients.

Abstract
INTRODUCTION The increased visceral fat in patients with obesity can increase the technical difficulty of surgery. This study was performed to evaluate a preoperative 20-day very low-calorie diet for obesity before laparoscopic gastrectomy for gastric cancer. METHODS This prospective single-center study involved patients with obesity who were planning to undergo laparoscopic gastrectomy for gastric cancer. Obesity was defined according to the Japanese criteria: BMI ≥25 kg/m2 or waist circumference ≥85 cm in men and ≥90 cm in women. The patients underwent a preoperative 20-day very low-calorie diet and received nutritional counseling. Weight loss, body composition, visceral fat mass, and operative outcomes were evaluated. RESULTS Thirty-three patients were enrolled from September 2013 to August 2015. Their median age was 71 years, and 78.8% were men. Their median bodyweight and BMI were 72.3 kg (range, 53.8-82.5 kg) and 26.0 kg/m2 (range, 23.5-31.0 kg/m2 ), respectively. The patients achieved a mean weight loss of 4.5% (95% confidence interval [CI]: 3.8-5.1), corresponding to 3.2 kg (95%CI: 2.7-3.7 kg). Body fat mass was significantly decreased by a mean of 2.5 kg (95%CI: 1.9-3.1), whereas skeletal muscle mass was unaffected (mean: -0.20 kg [95%CI: -0.55-0.15]). The visceral fat mass reduction rate was high as 16.8% (range, 11.6%-22.0%). All patients underwent laparoscopic gastrectomy as planned. Severe postoperative morbidity (Clavien-Dindo grade ≥III) was seen in only one patient (3.0%). CONCLUSION The preoperative 20-day very low-calorie diet weight loss program is promising for the treatment of obesity before laparoscopic gastrectomy for gastric cancer.

Feasibility of laparoscopic total gastrectomy in overweight patients: Implications of less impact of overweight on laparoscopic versus open approach. World J Clin Cases 2018; 6:1094-1100. [PMID: 30613667 PMCID: PMC6306645 DOI: 10.12998/wjcc.v6.i16.1094] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2018] [Revised: 11/08/2018] [Accepted: 11/24/2018] [Indexed: 02/05/2023] Open
Abstract
AIM To investigate safety and oncological feasibility of laparoscopic total gastrectomy (LTG) in overweight (OW) patients.
METHODS Patients who underwent total gastrectomy (110 laparoscopic, 211 open) for gastric cancer between January 1999 and July 2016 were included. Propensity score matching selected 152 patients (76 laparoscopic, 76 open), which were subsequently divided into the OW (≥ 25) or non-OW (< 25) group by body mass index. Postoperative outcomes of laparoscopic versus open approaches were compared between OW and non-OW groups.
RESULTS In the propensity-matched population, baseline characteristics were comparable between the OW and non-OW groups for the laparoscopy and open groups. In the laparoscopy group, operative time was longer (P = 0.01) in the OW group, however, other perioperative results including complication rates were comparable between the non-OW and OW groups. In the open group, number of retrieved lymph nodes were less (P = 0.03) and local complication rate was more frequent (P = 0.03) in the OW group.
CONCLUSION LTG in OW patients remains technically challenging but can be performed safely. Our findings imply that OW has a lesser effect on the laparoscopic versus open approach to total gastrectomy.

Abstract
AIM To perform a meta-analysis to investigate the correlation between body mass index (BMI) and the short-term outcomes of laparoscopic gastrectomy (LG) for gastric cancer (GC) in Asian patients.
METHODS The PubMed, Cochrane, EMBASE, and Web of Science databases were searched for studies that focused on the impact of obesity on the short-term outcomes of LG for GC in Asian patients who were classified into a high BMI (BMI ≥ 25 kg/m2) or low BMI group (BMI < 25 kg/m2). The results are expressed using the pooled odds ratio (OR) for binary variables and standard mean difference (SMD) for continuous variables with 95% confidence interval (CI), and were calculated according to the fixed-effects model while heterogeneity was not apparent or a random-effects model while heterogeneity was apparent.
RESULTS Nine studies, with a total sample size of 6077, were included in this meta-analysis. Compared with the low BMI group, the high BMI group had longer operative time (SMD = 0.26, 95%CI: 0.21 to 0.32, P < 0.001), greater blood loss (SMD = 0.19, 95%CI: 0.12 to 0.25, P < 0.001), and fewer retrieved lymph nodes (SMD = -0.13, 95%CI: 0.18 to 0.07, P < 0.001). There was no significant difference between the high and low BMI groups in postoperative complications (OR = 1.12, 95%CI: 0.95 to 1.33, P = 0.169), the duration of postoperative hospital stay (SMD = 0.681, 95%CI: -0.05 to 0.07, P = 0.681), postoperative mortality (OR = 1.95, 95%CI: 0.78 to 4.89, P = 0.153), or time to resuming food intake (SMD = 0.00, 95%CI: -0.06 to 0.06, P = 0.973).
CONCLUSION Our meta-analysis provides strong evidence that despite being associated with longer operative time, greater blood loss, and fewer retrieved lymph nodes, BMI has no significant impact on the short-term outcomes of LG for GC in Asian patients, including postoperative complications, the duration of postoperative hospital stay, postoperative mortality, and time to resuming food intake. BMI may be a poor risk factor for short-term outcomes of LG. Other indices should be taken into account.

Abstract
PURPOSE Many studies have demonstrated the advantage of maintaining intraoperative deep neuromuscular block (NMB) with sugammadex. This trial is designed to evaluate the impact of muscle relaxation during laparoscopic subtotal gastrectomy on the oncological benefits, particularly in obese patients with gastric cancer. MATERIALS AND METHODS This is a double-blind, randomized controlled multicenter prospective trial. Patients with clinical stage I-II gastric cancer with a body mass index of 25 and over, who undergo laparoscopic subtotal gastrectomy will be eligible for trial inclusion. The patients will be randomized into a deep NMB group or a moderate NMB group with a 1:1 ratio. A total of 196 patients (98 per group) are required. The primary endpoint is the number of harvested lymph nodes, which is a critical index of the quality of surgery in gastric cancer treatment. The secondary endpoints are surgeon's surgical condition score, patient's sedation score, and surgical outcomes including peak inspiratory pressure, operation time, postoperative pain, and morbidity. DISCUSSION This is the first study that compares deep NMB with moderate NMB during laparoscopic gastrectomy in obese patients with gastric cancer. We hope to show the oncologic benefits of deep NMB compared with moderate NMB during subtotal gastrectomy. TRIAL REGISTRATION NUMBER ClinicalTrials.gov (NCT03196791), date of registration: October 10, 2017.

Abstract
The impact of BMI on survival in gastric cancer (GC) is not clear. We sought to explore the relationship between BMI and tumor site, clinicopathologic characteristics, postoperative complications, and prognosis in GC patients. Patients who underwent gastrectomy for GC between January 2011 and June 2016 formed the study cohort (n = 827). Patients were divided into three groups according to the BMI (in kg/m2): “low” (<18.5), “normal” (18.5–24.9), and “high” (≥25.0). The preoperative level of albumin and hemoglobin in the low BMI group was lower than that in the high BMI or normal BMI group ( P < 0.05). The prevalence of gastric-cardia cancer in the high BMI group was significantly higher than that in the low BMI group ( P = 0.001). The prevalence of gastric-antrum cancer in the high BMI group was significantly lower than that in the low BMI group ( P = 0.001) and the normal BMI group ( P = 0.004). The BMI of patients with gastric-cardia cancer was significantly higher than that of patients with gastric-body cancer ( P = 0.018) and gastric-antrum cancer ( P < 0.001). There were no significant differences among the three groups in terms of tumor size, TNM stage, depth of tumor invasion, degree of tumor differentiation, resection margin, lymph node metastasis, or postoperative complications. BMI was not an independent factor that influenced the prognosis. We found a relationship between BMI and GC site. A low BMI may be associated with a poor prognosis and a high BMI may be related to a favorable prognosis. BMI was not an independent factor that influenced GC prognosis.

Does high body mass index negatively affect the surgical outcome and long-term survival of gastric cancer patients who underwent gastrectomy: A systematic review and meta-analysis. Eur J Surg Oncol 2018; 44:1971-1981.

Abstract
BACKGROUND Whether high body mass index (BMI) was associated with increased postoperative complications and unfavorable prognosis of gastric cancer (GC) patients remain controversial. In the present study, we performed a systematic review and meta-analysis to evaluate the impact of high BMI on surgical outcome, postoperative complications and long-term survival of GC patients. METHODS The related studies were identified by searching PubMed and Embase databases. According to the BMI, all GC patients were classified into BMI ≥25 kg/m2 group and BMI <25 kg/m2 group. The relevant data was extracted and pooled effect size was assessed using a fixed effect model or random effect model. RESULTS A total of 36 relevant studies involving 30,642 GC patients were included in this meta-analysis. The results indicated that high BMI patients had longer operation time, fewer number of retrieved lymph nodes and larger amount of intraoperative blood loss than other patients, regardless of open gastrectomy or laparoscopic gastrectomy. In addition, the risk of postoperative complications was significantly higher in the patients with BMI ≥25 kg/m2 than in those with BMI <25 kg/m2, especially for infectious complications. However, high BMI had no negative impact on postoperative mortality and long-term survival of GC patients. CONCLUSION Despite the increased surgical difficulty and postoperative complications, high BMI was not associated with the prognosis of GC patients. To reduce the risk of postoperative complications, more meticulous operation technique and improved perioperative management should be necessary for high BMI patients.
