A meta-analysis evaluating wound infections and other complications following distal versus complete gastrectomy for gastric cancer. Int Wound J 2024; 21:e14516. [PMID: 38084020 PMCID: PMC10958092 DOI: 10.1111/iwj.14516] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Revised: 11/10/2023] [Accepted: 11/13/2023] [Indexed: 03/23/2024] Open
Abstract
A meta-analysis investigation was carried out to measure the wound infections (WIs) and other postoperative problems (PPs) of distal gastrectomy (DG) compared with total gastrectomy (TG) for gastric cancer (GC). A comprehensive literature investigation till February 2023 was used and 1247 interrelated investigations were reviewed. The 12 chosen investigations enclosed 2896 individuals with GC in the chosen investigations' starting point, 1375 of them were TG, and 1521 were DG. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were utilized to compute the value of the WIs and other PPs of DG compared with TG for GC by the dichotomous approaches and a fixed or random model. TG had significantly higher overall PP (OR, 1.58; 95% CI, 1.15-2.18, p = 0.005), WIs (OR, 1.69; 95% CI, 1.07-2.67, p = 0.02), peritoneal abscess (PA) (OR, 2.99; 95% CI, 1.67-5.36, p < 0.001), anastomotic leakage (AL) (OR, 1.90; 95% CI, 1.21-2.97, p = 0.005) and death (OR, 2.26; 95% CI, 1.17-4.37, p = 0.02) compared to those with DG in individuals with GC. TG had significantly higher overall PP, WIs, PA, AL and death compared to those with DG in individuals with GC. However, care must be exercised when dealing with its values because of the low sample size of some of the nominated investigations for the meta-analysis.

Abstract
Background Gastric cancer is one of the most common cancers worldwide and is the third most common cause of cancer related death. Improving postoperative results by understanding risk factors which impact outcomes is important. The current study aimed to compare immediate perioperative outcomes following gastrectomy. Methods 302 patients following gastric resections over a 10-year period (January 2009-January 2020) were identified in a database and retrospectively analysed. Epidemiological as well as perioperative data was analysed, and a univariate and multivariate analysis performed to identify risk factors for in-hospital mortality. Results In general, gastrectomies were mainly performed electively (total vs. subtotal 95% vs. 85%, p = 0.004). Patients having subtotal gastrectomy needed significantly more PRBC transfusions compared to total gastrectomy (p = 0.039). Most emergency surgeries were performed for benign diseases, such as ulcer perforations or bleeding and gastric ischaemia. Only emergency surgery was significantly associated with poorer overall survival (HR 2.68, 95% CI 1.32-5.05, p = 0.003). Conclusion In-hospital mortality was comparable between total and subtotal gastrectomies. Only emergency interventions increased postoperative fatality risk.

Abstract
OPINION STATEMENT The surgical treatment of gastric carcinoma has progressed significantly in the past few decades. A major milestone was the establishment of multimodal therapies for locally advanced tumours. Improvements in the technique of endoscopic resection have supplanted surgery in the early stages of many cases of gastric cancer. In cases in which an endoscopic resection is not possible, surgical limited resection procedures for the early stages of carcinoma are an equal alternative to gastrectomy in the field of oncology. Proximal gastrectomy is extensively discussed in this context. Whether proximal gastrectomy leads to a better quality of life and better nutritional well-being than total gastrectomy depends on the reconstruction chosen. The outcome cannot be conclusively assessed at present. For locally advanced stages, total or subtotal gastrectomy with D2 lymphadenectomy is now the global standard. A subtotal gastrectomy requires sufficiently long tumour-free proximal resection margins. Recent data indicate that proximal margins of at least 3 cm for tumours with an expansive growth pattern and at least 5 cm for those with an infiltrative growth pattern are sufficient. The most frequently performed reconstruction worldwide following gastrectomy is the Roux-en-Y reconstruction. However, there is evidence that pouch reconstruction is superior in terms of quality of life and nutritional well-being. Oncological gastric surgery is increasingly being performed laparoscopically. The safety and oncological equivalency were first demonstrated for early carcinomas and then for locally advanced tumours, by cohort studies and RCTs. Some studies suggest that laparoscopic procedures may be advantageous in early postoperative recovery. Robotic gastrectomy is also increasing in use. Preliminary results suggest that robotic gastrectomy may have added value in lymphadenectomy and in the early postoperative course. However, further studies are needed to substantiate these results. There is an ongoing debate about the best treatment option for gastric cancer with oligometastatic disease. Preliminary results indicate that certain patient groups could benefit from resection of the primary tumour and metastases following chemotherapy. However, the exact conditions in which patients may benefit have yet to be confirmed by ongoing trials.

Abstract
INTRODUCTION Major gastric surgery for distal esophageal and gastric cancer has a strong impact on the quality of life, morbidity, and mortality. Especially in elderly patients reaching their life expectancy, the responsible use and extent of gastrectomy are imperative to achieve a balance between harm and benefit. In the present study, the reimbursement database (German Diagnosis Related Groups (G-DRG) database) of the Statistical Office of the Federal Republic of Germany was queried to evaluate the morbidity and mortality of patients aged above or below 75 years following gastrectomy. MATERIAL AND METHODS All patients in Germany undergoing subtotal gastrectomy (ST), total gastrectomy (T), or gastrectomy combined with esophagectomy (TE) for gastric or distal esophageal cancer (International Statistical Classification of Diseases and Related Health Problems Version 10 (ICD-10) C15.2, C15.5, and C16.0-C16.9) between 2008 and 2018 were included. Intraoperative and postoperative complications as well as comorbidities, in-hospital mortality, and the extent of surgery were assessed by evaluating ICD-10 and operation and procedure key (Operationen- und Prozedurenschlüssel) codes. RESULTS A total of 67,389 patients underwent oncologic gastric resection in Germany between 2008 and 2018. In total, 21,794 patients received ST, 41,825 received T, and 3,466 received TE, respectively. In 304 cases, the combinations of these, in fact, mutually exclusive procedures were encoded. The proportion of patients aged 75 years or older was 51.4% (n = 11,207) for ST, 32.6% (n = 13,617) for T, and 28.1% (n = 973) for TE. The in-hospital mortality of elderly patients was significantly increased in all three groups. (p < 0.0001) General complications such as respiratory failure (p = 0.0054), acute renal failure (p < 0.0001), acute myocardial failure (p < 0.0001), and the need for resuscitation (ST/T: p < 0.0001/TE: p = 0.0218) were significantly increased after any kind of gastrectomy. Roux-en Y was the most commonly applied reconstruction technique in both young and elderly patients. Regarding lymphadenectomy, systematic D2 dissection was performed less frequently in older patients than in the younger collective in the case of ST and T as well as D3 dissection. Peritonectomy and hyperthermic intraperitoneal chemotherapy were uncommon in elderly patients alongside ST and T compared to younger patients (p < 0.0001). CONCLUSION The clinical outcome of major oncological gastric surgery is highly dependent on a patient's age. The elderly show a tremendously increased likelihood of in-hospital mortality and morbidity.

Abstract
Distal gastrectomy (DG) and total gastrectomy (TG) are the most common types of radical surgery for patients with middle-third gastric cancer (MTGC). However, the indications and benefits of the two procedures still remain controversial. The present meta-analysis aimed to compare the surgical and oncological outcomes of DG and TG in the treatment of MTGC. A rigorous literature review was performed in the databases of PubMed, Embase, Web of Science, China National Knowledge Infrastructure and Chinese BioMedical Literature to retrieve studies published up to February 2022. The Newcastle-Ottawa Scale was used to assess the quality of included studies and a meta-analysis was performed using RevMan 5.3 software. A total of 12 retrospective studies performing comparisons of DG and TG were included in the present meta-analysis. For patients who underwent DG, a lower rate of overall post-operative complications, anastomosis leakage and intro-abdominal infection was determined. No significant difference was observed between DG and TG in the 5-year overall survival when the proximal resection margin ranged from 3 to 5 cm. Although DG was associated with a higher 5-year overall survival rate when compared to TG, there was no significant difference in the stratified analyses by TNM stage. In conclusion, the prognosis of MTGC did not depend on the extent of gastrectomy. With lower complications and acceptable oncological outcomes, DG was a safe and feasible surgical procedure for MTGC when a negative proximal margin was confirmed.

Clinical Relevance of the Tumor Location-Modified Laurén Classification System for Gastric Cancer in a Western Population. Ann Surg Oncol 2022; 29:3911-3920. [PMID: 35041098 PMCID: PMC9072452 DOI: 10.1245/s10434-021-11252-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2021] [Accepted: 12/06/2021] [Indexed: 11/30/2022]
Abstract
Background The Tumor Location-Modified Laurén Classification (MLC) system combines Laurén histologic subtype and anatomic tumor location. It divides gastric tumors into proximal non-diffuse (PND), distal non-diffuse (DND), and diffuse (D) types. The optimum classification of patients with Laurén mixed tumors in this system is not clear due to its grouping with both diffuse and non-diffuse types in previous studies. The clinical relevance of the MLC in a Western population has not been examined. Methods A cohort study investigated 404 patients who underwent gastrectomy for gastric adenocarcinoma between 2005 and 2020. The classification of Laurén mixed tumors was evaluated using receiver operating characteristic (ROC) curve analysis and comparison of clinicopathologic characteristics (chi-square). Survival analysis was performed using multivariable Cox regression. Results The ROC curve analysis demonstrated a slightly higher area under the curve value for predicting survival when Laurén mixed tumors were grouped with intestinal-type rather than diffuse-type tumors (0.58 vs 0.57). Survival, tumor recurrence, and resection margin positivity in mixed tumors also was more similar to intestinal type. Distal non-diffuse tumors had the best 5-year survival (DND 64.7 % vs PND 56.1 % vs diffuse 45.1 %; p = 0.006) and were least likely to have recurrence (DND 27.0 % vs PND 34.3 % vs diffuse 48.3 %; p = 0.001). Multivariable analysis demonstrated that MLC was an independent prognostic factor for survival (PND: hazard ratio [HR], 1.64; 95 % confidence interval [CI], 1.16–2.32 vs diffuse: HR, 2.20; 95 % CI, 1.56–3.09) Conclusions The MLC was an independent prognostic marker in this Western cohort of patients with gastric adenocarcinoma. The patients with PND and D tumors had worse survival than those with DND tumors.

Abstract
Gastric adenocarcinoma is one of the most common and lethal cancers worldwide and is associated with a high frequency of nodal metastasis. The value of multimodality therapy is well-established, but gastric resection and locoregional lymph node dissection are important mainstays in potentially curative therapy. However, there has been considerable regional variation in surgical approach and debate regarding the ideal extent of gastric resection, gastric reconstruction, and extent of lymphadenectomy. This chapter outlines the current evidence in the surgical management of gastric adenocarcinoma. The advent of minimally invasive approaches to gastric operations is also discussed.

Abstract
BACKGROUND AND OBJECTIVES Gastrectomy for gastric cancer is associated with significant infective postoperative complications. C-reactive protein (CRP) is a useful biomarker in the early detection of infective complications following major abdominal surgery. This single-centre retrospective study aimed to determine the relationship between postoperative CRP levels and development of postoperative infective complications after gastrectomy. METHODS Daily postoperative CRP levels were analyzed to determine a CRP threshold associated with infective complications. ROC curve analysis was used to determine which postoperative day (POD) gave the optimal cutoff. Multivariate analysis was performed to determine significant factors associated with complications. RESULTS One hundred and forty-four patients were included. A total of 61 patients (42%) had at least one infective complication. A CRP level of 220 mg/L was associated with the highest AUC (0.765) with a sensitivity of 70% and specificity of 76% (positive predictive value, 67%; negative predictive value, 78%). More patients with a CRP > 220 mg/L on POD 3 developed infective complications (67% vs. 21%, p < 0.001). CONCLUSIONS A CRP of more than 220 mg/L on POD 3 may be useful to alert clinicians to the increased risk of a postoperative infective complication or enable earlier safe discharge from critical care for those with a lower value.

Abstract
INTRODUCTION AND AIMS Surgery is the main treatment for gastric cancer. D2 radical gastrectomy is associated with a variable postoperative morbidity and mortality rate worldwide. The aim of the present study was to identify the risk factors associated with the postoperative morbidity and mortality of D2 radical gastrectomy, with curative intent, for gastric cancer. MATERIALS AND METHODS A retrospective case series was conducted, in which the medical records were reviewed of patients with gastric cancer that underwent D2 radical gastrectomy, within the time frame of January 2014 and December 2018. Univariate and multivariate analyses were carried out to identify the risk factors related to postoperative morbidity and mortality within 90 days. RESULTS The percentages of postoperative morbidity and mortality in 691 patients were 23.3% and 3.3%, respectively. In the multivariate analysis, age ≥70 years (OR = 1.85, 95% CI: 1.25-2.76), ASA III-IV (OR = 2.06, 95% CI: 1.28-3.34), total gastrectomy (OR = 1.96, 95% CI:1.19-3.23), and pancreatosplenectomy (OR = 5.41, 95% CI: 1.42-20.61) were associated with greater postoperative morbidity, and age ≥70 years (OR = 4.92, 95% CI:1.78-13.65), lower BMI (OR = 0.81, 95% CI: 0.71-0.92), and hypoalbuminemia (OR = 0.91, 95% CI: 0.85-0.98) were associated with greater mortality in distal and total D2 radical gastrectomy. CONCLUSIONS D2 radical gastrectomy for gastric cancer was shown to be a safe treatment, with low postoperative morbidity and mortality rates. Age ≥70 years, ASA III-IV, total gastrectomy, and pancreatosplenectomy were factors associated with a higher complication rate. Age ≥70 years, lower BMI, and hypoalbuminemia were mortality predictors in distal and total radical gastrectomy.

Abstract
BACKGROUND With improved survival in gastric cancer patients, health-related quality of life has become an important clinical endpoint alongside primary oncological outcomes.
AIM To investigate health-related quality of life after various surgical procedures for gastric cancer treatment.
METHODS The validated Slovenian version of the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire (QLQ-C30) and its gastric cancer-specific module (QLQ STO-22) was sent for self-completion to patients that underwent curative resection for gastric adenocarcinoma between January 2014 and December 2018 at our centre. In total, 116 patients responded. Scores were compared between patients after subtotal distal vs total gastrectomy and patients after subtotal distal gastrectomy with Billroth II vs Roux-en-Y reconstruction.
RESULTS Interestingly, the extent of resection did not influence daily functioning; however, more dysphagia and eating restrictions were reported in patients after total gastrectomy when compared to patients after subtotal distal gastrectomy. Moreover, patients with Billroth II reconstruction after subtotal distal resection experienced worse physical and role functioning and reported more pain, fatigue and reflux compared to Roux-en-Y reconstruction.
CONCLUSION Based on our results, Roux-en-Y reconstruction after subtotal distal gastrectomy should be preferred over Billroth II reconstruction. The data obtained from this study will help surgeons when preoperatively informing their patients about expected functional outcomes after gastrectomy and enable them to ensure proper supportive care of their patients in the postoperative period.

Risk factors associated with postoperative morbidity and mortality in D2 radical gastrectomy for gastric cancer. REVISTA DE GASTROENTEROLOGIA DE MEXICO (ENGLISH) 2021; 87:S0375-0906(21)00013-6. [PMID: 33752940 DOI: 10.1016/j.rgmx.2020.11.004] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Revised: 09/30/2020] [Accepted: 11/12/2020] [Indexed: 11/24/2022]
Abstract
INTRODUCTION AND AIMS Surgery is the main treatment for gastric cancer. D2 radical gastrectomy is associated with a variable postoperative morbidity and mortality rate worldwide. The aim of the present study was to identify the risk factors associated with the postoperative morbidity and mortality of D2 radical gastrectomy, with curative intent, for gastric cancer. MATERIALS AND METHODS A retrospective case series was conducted, in which the medical records were reviewed of patients with gastric cancer that underwent D2 radical gastrectomy, within the time frame of January 2014 and December 2018. Univariate and multivariate analyses were carried out to identify the risk factors related to postoperative morbidity and mortality within 90 days. RESULTS The percentages of postoperative morbidity and mortality in 691 patients were 23.3% and 3.3%, respectively. In the multivariate analysis, age ≥ 70 years (OR=1.85, 95% CI: 1.25-2.76), ASA III-IV (OR=2.06, 95% CI: 1.28-3.34), total gastrectomy (OR=1.96, 95% CI:1.19-3.23), and pancreatosplenectomy (OR=5.41, 95% CI: 1.42-20.61) were associated with greater postoperative morbidity, and age≥70 years (OR=4.92, 95% CI:1.78-13.65), lower BMI (OR=0.81, 95% CI: 0.71-0.92), and hypoalbuminemia (OR=0.91, 95% CI: 0.85-0.98) were associated with greater mortality in distal and total D2 radical gastrectomy. CONCLUSIONS D2 radical gastrectomy for gastric cancer was shown to be a safe treatment, with low postoperative morbidity and mortality rates. Age≥70 years, ASA III-IV, total gastrectomy, and pancreatosplenectomy were factors associated with a higher complication rate. Age≥70 years, lower BMI, and hypoalbuminemia were mortality predictors in distal and total radical gastrectomy.

Abstract
OBJECTIVE To analyze the randomized controlled trials (RCTs) devoted to distal subtotal gastrectomy and gastrectomy with D2 lymphadenectomy in patients with distal gastric cancer. MATERIAL AND METHODS RCTs were searched in the electronic library, the Cochrane Community database, and PubMed database. A systematic review and meta-analysis were carried out in accordance with the recommendations of the Cochrane Community experts (Higgins et al. 2019). Mathematical calculations of a meta-analysis were made using RevMan 5.3 software package. Statistical criteria were calculated for relative risk (RR), hazard ratio (HR), 95% confidence interval (95% CI) and significance level (p). RESULTS Seven primary RCTs were selected. A total number of 1463 surgical interventions with D2 lymphadenectomy were observed (805 patients underwent distal subtotal gastrectomy, 658 - gastrectomy). Postoperative mortality is significantly higher (6.5% and 2.6%) after gastrectomy compared to subtotal distal gastrectomy (RR 2.2, 95% CI 1.34-3.64, I2 0%, fixed effect model). Postoperative complications are also significantly more common (28% and 14%) after gastrectomy (RR 1.72, 95% CI 1.16-2.55, I2 heterogeneity 49%, random effect model). Differences in overall five-year survival after gastrectomy and subtotal distal resection (51.6% and 60.8%) are insignificant (HR 0.74, 95% CI 0.45-1.22, I2 90%, random effect model, general reverse inversion). CONCLUSION The choice of distal subtotal gastrectomy and gastrectomy with D2 lymphadenectomy in patients with distal gastric cancer is not regulated by evidence-based medicine. The boundaries of minimal surgical clearance from the tumor edge vary from 2.5 cm to 6 cm. An updated meta-analysis shows that postoperative mortality and morbidity are significantly higher after gastrectomy compared to distal subtotal gastrectomy while overall 5-year survival is similar.

Abstract
BACKGROUND The impact of anastomotic leak (AL) on long-term outcomes after gastrectomy for gastric adenocarcinoma is poorly understood. This study determined whether AL contributes to poor overall survival. METHODS Consecutive patients undergoing gastrectomy in a single high-volume unit between 1997 and 2016 were evaluated. Clinicopathological characteristics, oncological and postoperative outcomes were stratified according to whether patients had no AL, non-severe AL or severe AL. Severe AL was defined as anastomotic leakage associated with Clavien-Dindo Grade III-IV complications. RESULTS The study included 969 patients, of whom 58 (6·0 per cent) developed AL; 15 of the 58 patients developed severe leakage. Severe AL was associated with prolonged hospital stay (median 50, 30 and 13 days for patients with severe AL, non-severe AL and no AL respectively; P < 0·001) and critical care stay (median 11, 0 and 0 days; P < 0·001). There were no significant differences between groups in number of lymph nodes harvested (median 29, 30 and 28; P = 0·528) and R1 resection rates (7, 5 and 6·5 per cent; P = 0·891). Cox multivariable regression analysis showed that severe AL was independently associated with overall survival (hazard ratio 3·96, 95 per cent c.i. 2·11 to 7·44; P < 0·001) but not recurrence-free survival. In sensitivity analysis, the results for patients who had neoadjuvant therapy then gastrectomy were similar to those for the entire cohort. CONCLUSION AL prolongs hospital stay and is associated with compromised long-term overall survival.

Abstract
Aim Gastric cancer is one of the most common cancers worldwide. In Turkey, stomach cancer is ranked 5th among men and 8th among women in all cancers and is located in the forefront in cancer-related deaths. Signet ring cell adenocarcinoma, which is the histopathological subtype of gastric cancer, has a poor prognosis. The incidence of signet ring cell adenocarcinoma is rising. In the present study, we aimed to describe the clinicopathologic features of signet ring cell adenocarcinoma. Materials and Methods A total of 79 patients with 30 being female (38%) and 49 male (62%) who were diagnosed with gastric signet ring cell adenocarcinoma in the Medical Oncology Department of Ankara Numune Training and Research Hospital between January 2004 and October 2015 were retrospectively evaluated. Results The baseline demographic characteristics of the patients, such as tumor localization, tumor stage, preoperative serum tumor markers, and treatment type (surgery and chemotherapy regimen), and the effects of these variables on survival and mortality were evaluated. Total surgery, stage III disease, moderate to poor grade, preoperative serum CA 19-9 and CEA levels were found as independent predictors of progression risk (p < 0.05). Each 1 ng/mL increase in preoperative serum CEA level was found to increase the risk of progression by 1.20 folds. Again, each 1 U/mL in preoperative serum CA 19-9 level was found to increase the risk of progression and mortality by 1.06 folds. Conclusion The clinicopathologic features of signet ring cell stomach cancer were described. Tumor localization and disease, CA 19-9 and CEA levels, and treatment type (surgery and chemotherapy regimen) were effective on survival and mortality. However, further studies with larger patient groups are needed on this issue. How to cite this article Altay SB, Akkurt G, Yılmaz N, et al.

Abstract
Purpose This study sought to examine whether near total gastrectomy (nTG) confers a long-term nutritional benefit when compared with total gastrectomy (TG) for the treatment of gastric cancer. Materials and Methods Patients who underwent nTG or TG for gastric cancer were included (n=570). Using the 1:2 matched propensity score, 25 patients from the nTG group and 50 patients from the TG group were compared retrospectively for oncologic outcomes, including long-term survival and nutritional status. Results The length of the proximal resection margin, number of retrieved lymph nodes and tumor nodes, metastasis stage, short-term postoperative outcomes, and long-term survival were not significantly different between the groups. The body mass index values, and serum total protein and hemoglobin levels of the patients decreased significantly until postoperative 6 months, and then recovered slightly over time (P<0.05); however, there was no difference in the levels between the groups. The prognostic nutritional index values and serum albumin levels decreased significantly until postoperative 6 months and then recovered (P<0.05); the levels decreased more in the nTG group than in the TG group (P<0.05). The mean corpuscular volumes and serum transferrin levels increased significantly until postoperative 1 year and then recovered slightly over time (P<0.05); however, there was no difference between the groups. Serum vitamin B12, iron, and ferritin levels of the patients did not change significantly over time, and no difference existed between the groups. Conclusions A small remnant stomach after nTG conferred no significant nutritional benefits over TG.

Abstract
BACKGROUND There still remains controversy for the choice of resection extent for gastric cancer involving the middle-third of the stomach. The aim of this study was to compare the technical feasibility and long-term outcomes of laparoscopy-assisted distal gastrectomy (LADG) versus laparoscopy-assisted total gastrectomy (LATG) for middle-third advanced gastric cancer (AGC) and to determine which is the optimal surgical procedure. METHODS For this study, clinical data for 379 patients who underwent LADG or LATG with D2 lymph node dissection between April 2005 and June 2014 were analyzed retrospectively. The short- and long-term outcomes were compared between the propensity score-matched groups. RESULTS The LADG group had a significantly shorter operating time (212.74 vs. 241.79 min, P < 0.001), less estimated blood loss (114.38 vs. 181.51 ml, P = 0.000), shorter first flatus and postoperative hospital stay. Additionally, the total cost of hospitalization was significantly higher in the LATG group than LADG group (71187.58 vs. 65783.25 RMB, P = 0.000). There were no significant differences in postoperative complications rate between the LADG group and the LATG group. The 5-year overall survival (OS) rates were 64.4% in the LADG group and 61.0% in the LATG group (P = 0.548). The resection extent was not an independent prognostic factor for the OS. CONCLUSIONS LADG with D2 nodal dissection is a feasible treatment strategy for middle-third AGC with better short-term outcomes and similar long-term survival rates compared with LATG. We recommended that DG should be the optimal surgical procedure for middle one-third AGC under the premise of negative proximal resection margin.
