Abstract
PURPOSE Evaluation of diagnostic value for lymph node (LN) metastasis and LN identification using indocyanine green (ICG) fluorescence in laparoscopic subtotal gastrectomy for gastric cancer. METHODS A prospective study on 79 patients who underwent radical subtotal gastrectomy with the use of ICG-guided LN dissection. The sensitivity and specificity of the ICG fluorescence lymphography method in detecting metastatic LNs were evaluated. RESULTS A total of 79 patients underwent surgery. The number of LNs was retrieved: 2992 LNs, of which 2392 were fluorescent (79.9%) and 600 were nonfluorescent (20.1%). The average number of LNs dissected was 37.7 ± 11.8 LNs, and the average number of fluorescent LNs was 30.3 ± 11.1; the LN metastasis rates in the total LNs and in the ICG group were 6.79% and 7.34%, respectively. The median number of retrieved LNs in patients with LN metastases (37 [IQR, 33-47]) was higher than in patients without LN metastases (36 [IQR, 27-43]), (P = .348). The median number of fluorescent LNs was significantly higher in patients with LN metastases (32 [IQR, 26-44]) than in those without LN metastases (26 [IQR, 21-36]; P < .001). The sensitivity of ICG in metastasis detection was 75.86% (22 of 29 patients), with a false-negative rate of 24.14% (7 of 29 patients). For the identification of metastatic LNs, the sensitivity of ICG was 90.7%, with the specificity of 20.8%. The negative predictive value of nonfluorescent LNs was 97%. CONCLUSION ICG fluorescence lymphography-guided lymphadenectomy can clearly visualize the lymphatic system and the LNs alongside the tumor. The high sensitivity in detecting metastatic LNs and the high negative predictive value of a nonfluorescent LNs suggest that this is an effective method for clinically radical gastrectomy for gastric cancer.

Abstract
Objectives Laparoscopic gastrectomy (LG) was challenging to most surgeons due to the two-dimensional view, difficult manipulations of the instruments, ergonomic discomfort, and the associated muscular spasm and effort. Technological advances with improved surgical experience, have made LG a more feasible and favorable approach for gastric cancer (GC) patients. Material and Methods LG was performed in 44 patients with GC between July 2015 to June 2022, in the Department of Surgical Oncology, Oncology Center, Mansoura University, Egypt, and we assessed the surgical outcomes of this approach as an initial experience of a single cancer center. Results Twenty-seven patients underwent laparoscopic distal gastrectomy, and seventeen underwent laparoscopic total gastrectomy. Two cases had combined resection. Operative time was 339.2 ± 76.73 min, while blood loss was 153.86 ± 57.51 mL. The patients were ambulant on postoperative day 0, oral intake was started within three days (range 1-5 days) and the hospital stay was six days (range 3-9 days). Conclusion LG for GC is a feasible approach for both early and advanced GC patients as it allows for adequate diagnosis of the peritoneal disease, meticulous dissection, and identification of the lymph nodes with minimal blood loss and decrease surgery-related problems and encourage the early patients' discharge from hospital and return to daily life activities.

Abstract
PURPOSE Lymph node (LN) metastasis is a crucial factor in the prognosis of patients with gastric cancer (GC) and is known to occur more frequently in cases with an advanced T stage. This study aimed to analyze the survival data of patients with advanced LN metastasis in T1 GC. MATERIALS AND METHODS From January 2008 to June 2018, 677 patients with pathological stage II GC who underwent radical gastrectomy were divided into an early GC group (EG: T1N2 and T1N3a, n=103) and an advanced GC (AGC) group (AG: T2N1, T2N2, T3N0, T3N1, and T4aN0, n=574). Short- and long-term survival rates were compared between the 2 groups. RESULTS A total of 80.6% (n=83) of the patients in the EG group and 52.8% (n=303) in the AG group had stage IIA AGC. The extent of LN dissection, number of retrieved LNs, and short-term morbidity and mortality rates did not differ between the 2 groups. The 5-year relapse-free survival (RFS) of all patients was 87.8% and the overall survival was 84.0%. RFS was lower in the EG group than in the AG group (82.2% vs. 88.7%, P=0.047). This difference was more pronounced among patients with stage IIA (82.4% vs. 92.9%, P=0.003). CONCLUSIONS T1 GC with multiple LN metastases seems to have a worse prognosis compared to tumors with higher T-stages at the same level. Adjuvant chemotherapy is highly recommended for these patients, and future staging systems may require upstaging T1N2-stage tumors.

Abstract
Since Dr. Kitano introduced laparoscopic distal gastrectomy for early gastric cancer in 1994, there have been remarkable advances in minimally invasive surgery (MIS) for gastric cancer, including robotic surgery. With the efforts of many clinical researchers and consenting patients, medical knowledge and evidence for laparoscopic surgery in gastric cancer have accumulated. Although many gastric surgeons are comfortable with the clinical application of laparoscopic surgery for early gastric cancer, the adoption of MISs for advanced gastric cancer remains controversial. In this review article, we describe the current status and evidence of MIS from an evidence‐based medicine viewpoint and explore the feasibility and effectiveness of MIS for advanced gastric cancer in the real world.

Abstract
Purpose The purpose of the present study was to evaluate whether vascular calcification is a risk factor for anastomotic leakage after gastrectomy in gastric cancer patients. Methods Patients with confirmed gastric cancer were collected from the database of a single clinical center from January 2013 to January 2019. The calcification score and anastomotic leakage were recorded, and predictors of anastomotic leakage were analyzed. Results A total of 856 patients were included in this study; 818 patients had no anastomotic leakage, and 38 patients had anastomotic leakage. The ratio of hypertension status (p=0.011), open gastrectomy (p=0.012), postoperative length of stay (p=0.000), aorta calcification score (p=0.000) and celiac axis calcification (p=0.000) were higher in the anastomotic leakage group than in the nonanastomotic leakage group. In multivariate analysis, aorta calcification (p=0.029, odds ratio =2.425, 95% CI=1.095–5.491) was an independent predictor of the anastomotic leakage. Conclusion Aorta calcification is an independent risk factor for anastomotic leakage after gastrectomy in gastric cancer patients.

Abstract
Introduction There has been an increasing interest for the laparoscopic treatment of early gastric cancer, especially among Eastern surgeons. However, the oncological effectiveness of Laparoscopic Gastrectomy (LG) for Advanced Gastric Cancer (AGC) remains a subject of debate, especially in Western countries where limited reports have been published. The aim of this paper is to retrospectively analyze short- and long-term results of LG for AGC in a real-life Western practice. Materials and methods All consecutive cases of LG with D2 lymphadenectomy for AGC performed from January 2005 to December 2019 at seven different surgical departments were analyzed retrospectively. The primary outcome was diseases-free survival (DFS). Secondary outcomes were overall survival (OS), number of retrieved lymph nodes, postoperative morbidity and conversion rate. Results A total of 366 patients with stage II and III AGC underwent either total or subtotal LG. The mean number of harvested lymph nodes was 25 ± 14. The mean hospital stay was 13 ± 10 days and overall postoperative morbidity rate 27.32%, with severe complications (grade ≥ III) accounting for 9.29%. The median follow-up was 36 ± 16 months during which 90 deaths occurred, all due to disease progression. The DFS and OS probability was equal to 0.85 (95% CI 0.81–0.89) and 0.94 (95% CI 0.92–0.97) at 1 year, 0.62 (95% CI 0.55–0.69) and 0.63 (95% CI 0.56–0.71) at 5 years, respectively. Conclusion Our study has led us to conclude that LG for AGC is feasible and safe in the general practice of Western institutions when performed by trained surgeons.

Abstract
BACKGROUND Endoscopic resection (ER) might affect subsequent laparoscopic gastrectomy (LG) because of the electrical coagulation, but the effect remains controversial. The purpose of this meta-analysis was to analyze the effect of ER on the short-term surgical outcomes of subsequent LG. MATERIALS AND METHODS The PubMed, EMBASE, and Cochrane Library databases were searched to find eligible studies published from inception to March 21, 2021. Short-term surgical outcomes were compared between the ER-LG group and the LG-only group. The registration ID of this current meta-analysis on PROSPERO is CRD42021238031. RESULTS Nine studies involving 3611 patients were included in this meta-analysis. The LG-only group had a higher T stage (T1-T2: OR=2.42, 95% CI=1.09 to 5.34, P=0.03; T3-T4: OR=0.41, 95% CI=0.19 to 0.91, P=0.03) than the ER-LG group. The ER-LG group showed a shorter operation time than the LG-only group (MD=-5.98, 95% CI=-10.99 to -0.97, P=0.02). However, no difference was found in operation time after subgroup analysis of propensity score matching studies. No significant difference was found in intraoperative blood loss, time to first oral feeding, or postoperative hospital stay between the ER-LG group and the LG-only group. And no significance was found in overall complications (OR=1.16, 95% CI=0.89 to 1.50, P=0.27), complications of grade ≥ II (OR=1.11, 95% CI=0.71 to 1.73, P=0.64), complications of grade ≥ III b (OR=1.47, 95% CI=0.49 to 4.43, P=0.49) between the ER-LG group and the LG-only group. CONCLUSIONS ER did not affect subsequent LG in terms of short-term outcomes, and the ER-LG group might have a shorter operation time than the LG-only group.

Abstract
Background Laparoscopic gastrectomy is an acceptable procedure for early-stage gastric cancer; however, most patients are diagnosed at an advanced stage and older age in Taiwan. The feasibility and safety of applying laparoscopic gastrectomy in daily practice remain unclear. This study aimed to examine the short- and long-term outcomes of laparoscopic gastrectomy versus open procedures. Methods From 2007 to 2015, 192 patients who underwent open gastrectomy and 189 patients who underwent laparoscopic gastrectomy for gastric cancer at a single center were included. Propensity score matching analysis was used to adjust selection biases associated with age, preoperative hemoglobin, the extent of resection, tumor size, and stage of the disease. The demographics, perioperative parameters, short-term postoperative results, and 5-year survival data were analyzed. Results Open gastrectomy was more frequently performed in the elderly, larger tumor size, advanced stage of the disease, and disease requiring total gastrectomy or combined organ resection. After propensity score matching, 108 patients with laparoscopic gastrectomy were compared to 108 patients with open gastrectomy. The morbidity rates were not different in both groups (25.9%), while hospital stay was shorter in the laparoscopic group (16.0 vs. 18.8 days, p = 0.04). The 5-year overall survival and disease-free survival were superior in the laparoscopic group (p = 0.03 and p = 0.01, respectively); however, the survival differences were not significant in the subgroup analysis by stage. Laparoscopic gastrectomy had fewer recurrences than open gastrectomy. The pattern of recurrence was not different between the groups. Conclusions Laparoscopic gastrectomy can be safely applied in both early and locally advanced gastric cancer without compromising oncologic outcomes. Trial registration Retrospective registration.

Abstract
BACKGROUND Data about whether laparoscopic gastrectomy (LG) is applicable in serosa-positive (pT4a) gastric cancer patients remain rare. The purpose of this study is to compare the perioperative and long-term outcomes between the laparoscopic and open gastrectomy (OG) in pT4a gastric cancer patients who underwent curative resection. METHODS A total of 1086 consecutive pT4a patients (101 patients with LG and 985 with OG) who underwent curative gastrectomy in a high-volume center between 2006 and 2016 were evaluated. Demographics, surgical, and oncologic outcomes were analyzed. Propensity score matching (PSM) analysis was performed to balance baseline confounders, and COX regression analysis was performed to identify independent prognostic factors. RESULTS After PSM adjustment, a well-balanced cohort comprising 101 patients who underwent LG and 201 who underwent OG was analyzed. Operative time (288.7 vs. 234.2 min; P < 0.001) was significantly longer, while estimated blood loss (172.8 vs. 220.7 ml; P < 0.001) was significantly less in the LG group compared with the OG group. There were no significant differences between groups in total number of harvested lymph nodes, postoperative stays, readmission rate, and postoperative complication rate. The 3-year overall survival (OS) rate was not significant different in the LG and OG groups (66.7% vs. 62.8%, P = 0.668), and the subsequent multivariate analysis revealed that the surgical approach was not an independent prognostic factor for OS (HR = 1.123; 95%CI: 0.803-1.570; P = 0.499). In sensitivity analysis including 78 pairs well-matched patients operated by an experienced surgeon, the results were similar to these for the matched entire cohort. CONCLUSION LG can be a safe and feasible approach for pT4a gastric cancer treatment. However, well-designed high-quality RCTs are expected to draw a definitive conclusion on this topic.

PeerJ 2021; 9:e10556. [PMID: 33614260 PMCID: PMC7879943 DOI: 10.7717/peerj.10556] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/20/2020] [Accepted: 11/22/2020] [Indexed: 12/12/2022] Open
Abstract
Background Gastric cancer (GC) is one of the most common carcinomas of the digestive tract, and the prognosis for these patients may be poor. There is evidence that some long non-coding RNAs(lncRNAs) can predict the prognosis of patients with GC. However, few lncRNA signatures have been used to predict prognosis. Herein, we aimed to construct a risk score model based on the expression of five lncRNAs to predict the prognosis of patients with GC and provide new potential therapeutic targets. Methods We performed differentially expressed and survival analyses to identify differentially expressed survival-ralated lncRNAs by using GC patient expression profile data from The Cancer Genome Atlas (TCGA) database. We then established a formula including five lncRNAs to predict the prognosis of patients with GC. In addition, to verify the prognostic value of this risk score model, two independent Gene Expression Omnibus (GEO) datasets, GSE62254 (N = 300) and GSE15459 (N = 200), were employed as validation groups. Results Based on the characteristics of five lncRNAs, patients with GC were divided into high or low risk subgroups. The prognostic value of the risk score model with five lncRNAs was confirmed in both TCGA and the two independent GEO datasets. Furthermore, stratification analysis results showed that this model had an independent prognostic value in patients with stage II-IV GC. We constructed a nomogram model combining clinical factors and the five lncRNAs to increase the accuracy of prognostic prediction. Enrichment analysis based on the Kyoto Encyclopedia of Genes and Genomes (KEGG) suggested that the five lncRNAs are associated with multiple cancer occurrence and progression-related pathways. Conclusion The risk score model including five lncRNAs can predict the prognosis of patients with GC, especially those with stage II-IV, and may provide potential therapeutic targets in future.

Abstract
Gastric cancer is still a major cause of death worldwide. While laparoscopic gastrectomy (LG) has gained evidence as a standard treatment for early gastric cancer in the distal stomach, there are still concerns regarding its application for gastric cancer in the upper stomach and advanced gastric cancer. Nevertheless, LG has shown to have faster recovery, shorter hospital stay, less pain, and less blood loss in many retrospective and prospective studies. The application of LG has now extended from conventional radical gastrectomy to novel approaches such as function-preserving gastrectomy and sentinel-node navigated surgery. Studies on the use of laparoscopy in treatment for stage IV gastric cancer are rare, but show that there may be some roles of LG in selected cases. With the development of new laparoscopic tools that augment human ability, the future of LG should move on from proving non-inferiority to demonstrating superiority compared to the traditional open gastrectomy.

Comparative outcomes between totally laparoscopic total gastrectomy with the modified overlap method for early gastric cancer and advanced gastric cancer: review of 149 consecutive cases. Wideochir Inne Tech Maloinwazyjne 2020; 15:437-445. [PMID: 32904610 PMCID: PMC7457201 DOI: 10.5114/wiitm.2020.96098] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/22/2020] [Accepted: 05/25/2020] [Indexed: 12/16/2022] Open
Abstract
Introduction Totally laparoscopic total gastrectomy (TLTG) for advanced gastric cancer (AGC) has not been conclusively substantiated. Aim To evaluate TLTG treatment of AGC by comparing its effectiveness and surgical outcomes to those of TLTG treatment of early gastric cancer (EGC). Material and methods We performed TLTG with the (modified) overlap method for 149 gastric cancer cases between March 2012 and December 2018. We evaluated clinicopathologic characteristics, complications (including esophagojejunostomy site complications), and surgical outcomes. We also evaluated these variables in terms of their associations with EGC and AGC. Results Ninety-two males and 57 females, with a mean age of 60.7 years, were included. The mean operation time was 147.7 min. The mean number of harvested lymph nodes was 39.6. Thirteen (8.7%) patients experienced early complications, and 6 (4.0%) experienced late complications (Clavien-Dindo classification ≥ III). Eight (5.4%) patients underwent reoperation, and 8 (5.4%) were readmitted due to complications. There were no statistically significant differences in operation time, hospital stay, or surgical mortality between EGC and AGC. However, there were significant differences in early complications, late complications, rate of reoperation, and rate of readmission between EGC and AGC. Conclusions Although it has some limitations, TLTG with the (modified) overlap method for AGC treatment is feasible, safe, and associated with favorable outcomes.

Laparoscopic gastrectomy and metastasectomy for stage IV gastric cancer. Surg Endosc 2020; 35:1879-1887. [PMID: 32342215 DOI: 10.1007/s00464-020-07592-7] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2019] [Accepted: 04/22/2020] [Indexed: 12/21/2022]
Abstract
BACKGROUND The standard recommended treatment of stage IV gastric cancer is palliative chemotherapy. The aim of this study is to evaluate the role of radical gastrectomy with metastasectomy in these patients, as well as to explore the feasibility and safety of a laparoscopic approach. METHODS 117 consecutive patients with pathologically proven Stage IV gastric cancer who underwent radical gastrectomy with metastasectomy were enrolled in this study. We evaluated short-term and long-term outcomes, comparing laparoscopic surgery with open surgery by propensity score matching. RESULTS The 5-year overall survival rate (OSR) was 23.2% and the median survival time (MST) was 19.8 months. After propensity scoring matching, the 5-year OSR and MST of laparoscopy group was 23.4%, 17.9 months and in the open group, it was 25.0%, 22.8 months (p = 0.882). The complication rate was 5.6% in the laparoscopy group and 23.4% in the open group (p = 0.069). In multivariate analysis, adjuvant chemotherapy, chemotherapy cycle, and postoperative complication were independent prognostic factors of overall survival. CONCLUSIONS Radical gastrectomy with metastasectomy could have a potential role in stage IV gastric cancer. Laparoscopic gastrectomy with metastasectomy in selected stage IV gastric cancer patients is safe and feasible.
