Feasibility and long-term survival of proximal gastrectomy after neoadjuvant therapy for locally advanced proximal gastric cancer: A propensity-score-matched analysis. Chin Med J (Engl) 2024:00029330-990000000-01165. [PMID: 39090777 DOI: 10.1097/cm9.0000000000003232] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2023] [Indexed: 08/04/2024] Open
Abstract
BACKGROUND Neoadjuvant therapy enhances the possibility of achieving radical resection and improves the prognosis for locally advanced gastric cancer (GC). However, there is a lack of evidence regarding the optimal extent of resection for locally advanced proximal GC after neoadjuvant therapy. METHODS In this study, 330 patients underwent resection in Peking University Cancer Hospital, with curative intent after neoadjuvant therapy for histologically confirmed proximal GC from January 2009 to December 2022. Among them, 45 patients underwent proximal gastrectomy (PG), while 285 underwent total gastrectomy (TG). RESULTS In this study, 45 patients underwent proximal gastrectomy (PG), while 285 underwent total gastrectomy (TG). After propensity-score matching, 110 patients (71 TG and 39 PG) were included in the analysis. No significant differences between PG and TG regarding short-term outcomes and long-term prognosis were found. Specifically, PG demonstrated comparable overall survival to TG (P = 0.47). Subgroup analysis revealed that although not statistically significant, PG showed a potential advantage over TG in overall survival for patients with tumor-long diameters less than 4 cm (P = 0.31). However, for those with a long diameter larger than 4 cm, TG had a better survival probability (P = 0.81). No substantial differences were observed in baseline characteristics, surgical safety, postoperative recovery, and postoperative complications. CONCLUSION For locally advanced proximal GC with objective response to neoadjuvant therapy (long diameter <4 cm), PG is an alternative surgical procedure. Further research and prospective studies are warranted to validate these findings and guide clinical decision-making.

Abstract
Gastric cancer remains a significant global health concern and its surgical management approaches have undergone significant changes in South Korea and worldwide. Subtotal or total gastrectomy with D2 lymph node dissection is well established as a standard surgical procedure for gastric cancer. With the active implementation of cancer screening in South Korea, the proportion of early gastric cancer cases has significantly increased over the past few decades, leading to a steady increase in the survival rate among patients. Furthermore, recent advances in surgical instruments and techniques have made minimally invasive surgery increasingly prevalent, not only for early but also for advanced gastric cancer. We aim to provide a comprehensive overview of the evolution and current status of gastric cancer surgery in South Korea.

Abstract
The management of patients with vitamin B12 deficiency after total gastrectomy (TG) remains controversial. We aimed to evaluate the effect of vitamin B12 replacement intervals on the clinical characteristics in these patients. The data from patients who received vitamin B12 supplementation after TG between 2007 and 2018 at the National Cancer Center, Korea, were retrospectively evaluated. Vitamin B12 deficiency was defined as a serum vitamin B12 level of <200 pg/mL or urine methylmalonic acid level > 3.8 mg/gCr. The patients were divided into a regular replacement group (patients received an intramuscular injection or oral medication regularly), and a lab-based replacement group (patients received vitamin B12 intermittently after checking the level). The symptoms and biochemical parameters were compared between these groups. The regular and lab-based replacement groups included 190 and 216 patients, respectively. The median vitamin B12 replacement intervals were 1 and 9 months, respectively (p < 0.001). After replacement, the regular replacement group had higher vitamin B12 levels than the lab-based replacement group (p < 0.001). However, the serum hemoglobin level showed no significant changes. After replacement, there was no significant difference in the proportion of the symptomatic patients between the groups. Replacing vitamin B12 with a lab-based protocol may be sufficient for TG patients.

Abstract
PURPOSE In this western study, we aimed to compare perioperative outcomes, postoperative complications, and overall survival in patients who underwent total gastrectomy (TG) or proximal gastrectomy (PG) for proximal gastric cancer (GC). METHODS Patients who underwent GC surgery at Marmara University Hospital between January 2014 and December 2021 were evaluated retrospectively. Propensity score matching (PSM) was performed to balance the baseline characteristics of patients undergoing PG and TG. Data on patients' demographics, clinicopathological features of tumors, complications, and survival rates were analyzed. Perioperative outcomes and overall survival of the patients were compared between PG and TG groups. RESULTS A total of 212 patients were included in this study, with 53 patients in the PG and 159 in the TG group. After 1:1 matching according to PSM, 46 patients in the PG group were matched to 46 in the TG group. After PSM, there were no differences in clinicopathological outcomes except retrieved lymph nodes. In terms of short-term outcomes, overall perioperative morbidity (Clavien Dindo ≥ 3a) was significantly higher in the PG group (p = 0.01). However, there was no significant difference when the complications were considered separately. In the long-term follow-up, reflux esophagitis was associated with the PG group (p=0.04). In multivariate analysis, positive surgical margin and lymphovascular invasion were significant factors related to overall survival. Overall, 5-year survival was 55% in matched patients. The difference in survival was not statistically significant (57 vs. 69 months, p = 0.3) between the two groups. CONCLUSIONS Proximal gastrectomy is applicable to patients up to stage 3 disease, with no difference in overall survival, with caution in early complications and reflux esophagitis. Among all demographic and oncological factors, lymphovascular invasion and resection margin were significantly associated with worse survival.

Abstract
BACKGROUND Proximal gastrectomy (PG) has been excluded from the arsenal of western surgical oncologists for fear of bile reflux and diet intolerance. However, it is often an appropriate, less morbid operation for patients requiring resection of a proximal gastric cancer. METHODS Between 2013 and 2017, we performed 19 PG and 37 total gastrectomies (TGs), of whom 15 and 25 were alive at the time of data collection. In this single-center series, we present findings of a 10-question interview of patients who underwent proximal (n = 8) or TG (n = 16) regarding postgastrectomy food-related symptoms, based on a modified version of the validated Postgastrectomy Syndrome Assessment Scale. RESULTS Out of 7 Likert scale questions, there were no statistically significant differences between the groups regarding bile reflux, early satiety, appetite, energy level, physical activity limitations, pain, or general dissatisfaction with their surgery. Patients from both groups reported eating similar amounts of their preoperative volume per meal and overall food volume for the day. Both groups reported eating a similar number of snacks and meals throughout the day. Food satisfaction scores, calculated by summation of the Likert scores, were not different. CONCLUSION Although limited by the small population, we did not find a clinically relevant difference in food-related symptoms comparing PG and TG patients. This pilot study suggests that PG is an appropriate alternative to TG in certain populations. Anecdotal beliefs regarding potential bile reflux or diet intolerance should be reconsidered.

Abstract
Background The feasibility of using laparoscopic proximal gastrectomy (LPG) for the treatment of proximal early gastric cancer (EGC) has not been addressed. This study aimed to comparatively evaluate the effects on LPG with piggyback jejunal interposition double-tract reconstruction (PJIDTR) versus laparoscopic total gastrectomy (LTG) with Roux-en-Y reconstruction (overlap method) using propensity score matching for proximal EGC. Materials and Methods We examined the clinical outcomes of LPG with PJIDTR for proximal EGC. We retrospectively collected data from patients with proximal EGC who were treated at Shanxi Cancer Hospital between January 2012 and December 2015. The complication rate, nutritional indicators, reflux oesophagitis incidence and overall survival were compared between LTG and LPG with PJIDTR. Results Of the 424 patients, 200 were excluded, and 50 of the remaining patients received LPG with PJIDTR. Fifty matched LTG patients were screened. The incidence of early complications was 14% in the LPG group and 16% in the LTG group (P > 0.05). At 1 year after surgery, nutrition indices in the LPG group were significantly better than those in the LTG group (P < 0.05). One year after surgery, the Visick score II rate was 2% and 4%, and the endoscopic oesophagitis rate was 4% and 6% in the LPG and LTG groups, respectively. No tumour recurrence was observed in either group. The 5-year overall survival rates of the two groups were 98% and 90% (P = 0.08). Conclusions LPG with PJIDTR may be suitable for proximal EGC.

Abstract
Gastric cancer still remains a major cause of cancer-related deaths globally. Stage-adapted, individualized treatment is crucial to achieving optimal oncological outcomes. Postoperative morbidity and accurate nodal staging are heavily influenced by the extent of lymph node dissection. On one hand, insufficient lymphadenectomy may result in understaging and undertreatment of a patient, on the other hand, unnecessary lymph node dissection may result in a higher rate of postoperative complications. Approximately one-third of patients with gastric cancer undergoes an avoidable lymph node dissection. Many of the recent treatment updates in the management of gastric cancer have a major influence on both surgical and oncological approaches. Currently, a wide range of endoscopic, minimally invasive, and hybrid surgical techniques are available. The concept of sentinel node biopsy and utilization of the Maruyama Computer Program are significant components of stage-adapted gastric cancer surgery. Likewise, centralization and application of national guidelines, widespread use of neoadjuvant therapy, and the stage migration phenomenon are serious concerns to be discussed. Our goal is to review the available surgical strategies for gastric cancer, with a primary focus on lymphadenectomy.

Abstract
BACKGROUND The incidence of adenocarcinoma of the esophagogastric junction (AEG) has rapidly increased in recent years. Popular surgical approaches for AEG are proximal gastrectomy (PG) and total gastrectomy (TG), but it is controversial as to which approach is superior. Therefore, we conducted a systematic review and meta-analysis to evaluate the short- and long-term clinical outcomes of PG and TG for AEG. METHODS PubMed, Embase, Web of Science, and Cochrane Library were searched from inception to 1 June 2021. The Newcastle-Ottawa scale was used to conduct quality assessments, and RevMan (Version 5.4) was used to perform the meta-analysis. RESULTS In all, 1,734 patients with Siewert II/III AEG in 12 studies were included in the meta-analysis. PG was associated with less number of harvested lymph nodes (WMD = - 9.00, 95% CI - 12.61 to - 5.39, P < 0.00001), smaller tumor size (WMD = - 1.02, 95% CI - 1.71 to - 0.33, P = 0.004), shorter hospital length of stay (WMD = - 3.99, 95% CI - 7.27 to - 0.71, P = 0.02), and better long-term nutritional status compared with TG. Overall complications, other complications, and overall survival were not significantly different between the two groups. Moreover, subgroup analysis revealed that the occurrence of anastomotic strictures and reflux esophagitis was associated with the use of novel gastrointestinal tract (GI) anastomoses (double-tract reconstruction, jejunal interposition, and semi-embedded valve anastomosis) after PG. CONCLUSIONS Based on the available evidence, we recommend that surgeons accept PG combined with multiple novel anastomoses as an optimal surgical approach in patients diagnosed with resectable Siewert type II/III AEG.

Spade-Shaped Anastomosis after Laparoscopic Proximal Gastrectomy Using Double Suture Anchoring between the Posterior Wall of the Esophagus and the Anterior Wall of the Stomach (SPADE Operation): A Case Series. Cancers (Basel) 2022; 14:cancers14020379. [PMID: 35053541 PMCID: PMC8773864 DOI: 10.3390/cancers14020379] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2021] [Revised: 01/03/2022] [Accepted: 01/11/2022] [Indexed: 02/04/2023] Open
Abstract
Simple Summary SPADE is a novel reconstruction technique that is performed after laparoscopic proximal gastrectomy to reduce reflux. The aim of this study was to demonstrate the clinical outcomes of SPADE operations. Only one patient (2.9%) had reflux symptoms, which required anti-reflux drugs and reflux esophagitis on postoperative endoscopy. No anastomotic leakage was observed after the SPADE method. The rate of strictures at the site of anastomosis was 14.7%, and these patients were well managed with endoscopic ballooning. Therefore, the SPADE operation is a promising reconstruction method after proximal gastrectomy. Abstract We introduced SPADE operation, a novel anastomotic method after laparoscopic proximal gastrectomy (PG). Technical modifications were performed and settled. This report aimed to demonstrate the short-term clinical outcomes after settlement. Data from 34 consecutive patients who underwent laparoscopic PG with SPADE between June 2017 and March 2020 were retrospectively reviewed. Reflux was evaluated based on the patients’ symptoms and follow-up endoscopy using Los Angeles (LA) classification and RGB Classification (Residue, Gastritis, Bile). Other complications were classified using the Clavien–Dindo method. The incidence of reflux esophagitis was 2.9% (1/34). Bile reflux was observed in six patients (17.6%), and residual food was observed in 16 patients (47.1%) in the endoscopy. Twenty-eight patients had no reflux symptoms (82.4%), while five patients (14.7%) and one patient (2.9%) had mild and moderate reflux symptoms, respectively. The rates of anastomotic stricture and ileus were 14.7% (5/34) and 11.8% (4/34), respectively. No anastomotic leakage was observed. The incidence of major complications (Clavien-Dindo grade III or higher) was 14.7%. The SPADE operation following laparoscopic PG is effective in reducing gastroesophageal reflux. Its clinical usefulness should be validated using prospective clinical trials.

Abstract
BACKGROUND There is controversy regarding the long-term prognosis and short-term postoperative complications of different surgical strategies for proximal gastric cancer (PGC). METHODS We searched for articles published in Embase (Ovid), Medline (Ovid), PubMed, Cochrane Library, and Web of Science between January 1, 1990, and February 1, 2021. We screened out the literature comparing different surgical strategies. We then evaluated the long-term and short-term outcome of different surgical strategies using a network meta-analysis, which summarizes the hazard ratio, odds ratio, mean difference, and 95% confidence interval. RESULTS There were no significant differences between different surgical strategies for 5-year overall survival (OS), anastomotic leakage, or weight loss after 1 year. Compared with total gastrectomy with Roux-en-Y reconstruction (TG-RY) and proximal gastrectomy with double tract reconstruction (PG-DTR), the proximal gastrectomy with esophagogastrostomy (PG-EG) strategy significantly increased the incidence of reflux esophagitis; and the operation time and blood loss of the PG-EG strategy were significantly less than those of the other surgical strategies. The anastomotic stenosis rates of the PG-EG and proximal gastrectomy with jejunum interstitial (PG-JI) strategies were significantly higher than those of TG-RY and PG-DTR; the hemoglobin level after 1 year for the PG-DTR strategy was significantly higher than that of the TG-RY strategy. CONCLUSION Our comprehensive literature research found that different surgical strategies had no significant difference in the long-term survival of PGC, but the incidence of reflux esophagitis and anastomotic stenosis after PG-DTR and TG-RY was significantly reduced.

Abstract
Countries differ in their treatment expertise and research results regarding gastric cancer; hence, treatment guidelines are diverse based on evidence and medical situations. A comprehensive and comparative review of each country’s guidelines is imperative to understand the similarities and differences among countries. We reviewed and compared five gastric cancer treatment guidelines in terms of endoscopic, surgical, perioperative, and palliative systemic treatment based on evidence levels and recommendation grades, as well as the postoperative follow-up strategies for each guideline. The Korean, Chinese, and European guidelines provided evidence and grading of the recommendations. The United States guidelines suggested categories for evidence and consensus. The Japanese guidelines suggested evidence and recommendations only for systemic treatment. The Korean and Japanese guidelines described endoscopic treatment, surgery, and lymphadenectomy in detail. The Chinese, United States, and European guidelines more intensively considered perioperative chemotherapy. In particular, the indications for chemotherapy and the regimens recommended by each guideline differed slightly. Considering their medical situations, each guideline had some diversity in terms of adopting evidence, which resulted in heterogeneous recommendations. This review will help medical personnel to comprehensively understand the diversity in gastric cancer treatment guidelines for each country in terms of evidence and recommendations.

The type of gastrectomy affects skeletal muscle loss and the long-term outcomes of elderly patients with gastric cancer: a retrospective study using computed tomography images. Surg Today 2021; 52:812-821. [PMID: 34837102 DOI: 10.1007/s00595-021-02414-2] [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: 06/14/2021] [Accepted: 08/23/2021] [Indexed: 02/07/2023]
Abstract
PURPOSE Sarcopenia is common in elderly gastrectomized patients and a known risk factor for postoperative complications and poor overall survival. However, the long-term outcomes of skeletal muscle loss after gastrectomy and the differences in outcomes of different gastrectomy procedures remain unclear. METHODS The subjects of this retrospective study were 136 patients who underwent various gastrectomy procedures for early gastric cancer, namely: total gastrectomy (TG; n = 20), proximal gastrectomy (PG; n = 16), distal gastrectomy (DG; n = 60), and pylorus-preserving gastrectomy (PPG; n = 40). Skeletal muscle volume (SMV), calculated as the skeletal muscle index (SMI), was measured using cross-sectional computed tomography (CT) scans preoperatively and then 1, 2, and 3 years after gastrectomy. RESULTS Sarcopenia developed from 2 years onwards in all the patients who underwent TG. The SMI and sarcopenia prevalence after gastrectomy deteriorated over time. Multivariate analysis revealed that TG and PG were significant risk factors for skeletal muscle loss in postoperative years 1 and 3. A decrease in the SMI after TG or PG was most remarkable in elderly patients. CONCLUSIONS The type of gastrectomy affects skeletal muscle loss in the long term. Elderly patients who undergo TG or PG are at high risk of severe skeletal muscle loss.

Abstract
PURPOSE The optimal surgical procedure, whether total gastrectomy (TG) or proximal gastrectomy (PG), for Siewert type II/III adenocarcinoma of esophagogastric junction (AEG) has not been standardised, primarily because the optimal extent of lymph node (LN) dissection for AEG based on the metastatic rate of perigastric LNs remains under debate. The aim of this study was to investigate the metastatic incidence and prognostic significance of lower perigastric lymph nodes (LPLN), including No.4d, 5, 6 and 12a LN stations, in Siewert type II/III AEG. METHODS A total of 701 patients with Siewert type II/III AEG who received transabdominal open gastrectomy (425 patients with TG and 276 patients with PG) from 2010 to 2015 in West China Hospital were retrospectively included. Based on the clinicopathological information of TG patients, the risk factors of LPLN-positive patients were evaluated, and the metastatic incidence as well as the therapeutic value (TV) index of each LN station was assessed. Moreover, the 5-year overall survival (OS) rates between LPLN-positive and LPLN-negative groups were compared in TG patients, and the postoperative survival difference between TG and PG patients was also compared, using propensity score matching (PSM) method. RESULTS Tumour size (≥ 5 cm, OR = 1.481, p = 0.002) and pT stage (pT4, OR = 2.755, p = 0.024) were significant risk factors for patients with LPLN metastasis. For patients with tumour size more than 5 cm or pT4 stage, the metastatic rates of LPLN for Siewert type II, III and II/III AEG were 31.67%, 34.69% and 33.03%, whereas the TV indexes of LPLN for them were 5.76, 5.62 and 5.38, respectively. LPLN was a significant independent prognostic factor (HR = 1.422, p = 0.028), and positive LPLN was related to worse prognosis (p < 0.05). For patients with tumour size more than 5 cm or pT4 stage, TG patients were illustrated to have a better prognosis than PG patients, with 5-year OS rates of 58.9% vs 38.2% for Siewert type II AEG (χ2 = 4.159, p = 0.041), 68.9% vs 50.2% for Siewert type III AEG (χ2 = 5.630, p = 0.018) and 65.1% vs 40.3% for Siewert type II/III AEG (χ2 = 12.604, p < 0.001), respectively. CONCLUSIONS LPLN metastasis is a poor prognostic factor for patients with Siewert II/III AEG. LPLN dissection may improve the long-term survival of patients with tumour size more than 5 cm or pT4 stage, and TG might be more suitable for this kind of cancer.

Abstract
BACKGROUND The incidence of proximal gastric cancer in the gastric fundus, cardia, and other parts is increasing rapidly. The purpose of this study was to systematically compare the short-term and long-term clinical effects of proximal gastrectomy with double tract reconstruction (PG-DTR) to total gastrectomy (TG) for proximal early gastric cancer (EGC). METHODS A systematic review and meta-analysis was conducted through searching the literature in PubMed, Web of Science, Cochrane Library, EMBASE, CNKI, WAN FANG, and VIP databases. All clinical controlled trials and randomized controlled trials (RCTs) of PG-DTR and PG were included. Simultaneously, the relevant data were extracted, and the software RevMan version 5.1 was used for the meta-analysis. RESULTS Eight studies with a total of 753 patients were eligible for the meta-analysis. There were no significant differences in the operation time, intraoperative blood loss, postoperative hospital stay, early complications (anastomotic fistula and anastomotic bleeding), late complications (reflux symptoms and anastomotic stenosis), and 5-year survival rate between PG-DTR and TG. However, the levels of partial nutritional indicators (vitamin B12 supplements and vitamin B12 deficiency) were significantly higher in the PG-DTR group than in the TG group. CONCLUSION This study showed ample evidence to suggest that PG-DTR improved the postoperative nutritional status without compromising patient safety while providing the same surgical characteristics and postoperative morbidity as TG.

Abstract
BACKGROUND To analyze the characteristics, related risk factors, and prognosis of lymph node metastasis (Number [No.] 5 and No.6) in the group of adenocarcinoma of esophagogastric junction (AEG). METHODS The patients with Siewert II AEG who underwent total gastrectomy and D2 lymph node dissection from September 2015 to December 2018 in Lanzhou University Second Hospital were enrolled in this study. The pathological features of the postoperative specimens were analyzed (sex, age, maximum diameter, location, depth of invasion, degree of differentiation, neurological and vascular invasion, etc), and the lymph node metastasis rate of No.5, No.6 groups were calculated. The analysis was performed by IBM SPSS statistical software. The risk factors associated with lymph node metastasis in No.5 and No.6 groups were analyzed. Survival analysis was performed by Kaplan-M method, and survival rate was estimated, Log-rank test was used for comparison, and the difference was statistically significant at P < .05. RESULTS There were 142 cases of Siewert type II AEG with the positive rate of No.5 lymph nodes being 10.81% (8/74), and the positive rate of No.6 lymph nodes was 8.33% (11/132). No.5 and No.6 lymph nodes metastasis were not associated with gender, age, tumor maximum diameter, location (cardiac left/cardiac right) (P > .05), and were associated with invasion depth, differentiation degree, nerve and vascular invasion (P < .05). In the No.5 lymph node-positive group, the 3-year Overall Survival (OS) was 25.0%, and the No.5 lymph node-negative group had a 5-year OS of 57.8%, which was statistically different (P < .05). The 3-year OS was 18.2% in No.6 node-positive group and 53.8% in No.6 node-negative group, and the difference was statistically significant (P < .05). CONCLUSION For Siewert type II AEG, the lymph node metastasis rate was higher in No.5 and No.6 groups when the tumor invaded all layers of gastric wall and was poorly differentiated complicated with vascular nerve invasion, and the lymph node metastasis rate was lower at 3 years, which may be more appropriate for total gastrectomy +D2 lymph node dissection.

Abstract
Background Currently, the surgical approach to adenocarcinomas of esophago-gastric junction (AEG) remains controversial. Function-preserving gastric surgeries are becoming more popular, with proximal gastrectomy with double-tract anastomosis being one of the most important for AEG. Meanwhile, with the increasing use of laparoscopic techniques in the treatment of gastric cancer, the safety and effectiveness of laparoscopic-assisted proximal gastrectomy with double-tract anastomosis for Siewert type II-III AEG need to be further clarified. Methods Data of patients with Siewert type II/III AEG was collected at our center from October 2010 to December 2019 were retrospectively analyzed. 61 patients underwent open proximal gastrectomy with double-tract anastomosis (OPG-DT group) and 52 underwent laparoscopic-assisted proximal gastrectomy with double-tract anastomosis (LAPG-DT group). The clinical features, surgery, and short-term outcomes of patients in these 2 groups were collected to assess the safety and feasibility of LAPG-DT. Results A total of 113 patients were analyzed, there were 98 males and 15 females. No death during the operation. The differences in the number of lymph nodes, time to first flatus time to first eating, postoperative hospital stay, Additional analgesics were not statistically significant between two groups. Although the operative duration of LAPG-DT group was significantly longer than that of the OPG-DT group [(217±61) vs. (161±14) min, P=0.000), while less blood loss and less stress in LAPG-DT group. Early and late postoperative complications were similar between two groups. Conclusions Although laparoscopic-assisted proximal gastrectomy with double-tract anastomosis requires long operative time, it is associated with less bleeding and milder stress. Therefore, it is a safe and feasible surgical method.

Abstract
BACKGROUND The appropriate surgical procedure for patients with upper third early gastric cancer is controversial. We compared total gastrectomy (TG) with proximal gastrectomy (PG) in this patient population. METHODS A multicenter, non-randomized trial was conducted, with patients treated with PG or TG. We compared short- and long-term outcomes between these procedures. RESULTS Between 2009 and 2014, we enrolled 254 patients from 22 institutions; data from 252 were included in the analysis. These 252 patients were assigned to either the PG (n = 159) or TG (n = 93) group. Percentage of body weight loss (%BWL) at 1 year after surgery, i.e., the primary endpoint, in the PG group was significantly less than that of the TG group (- 12.8% versus - 16.9%; p = 0.0001). For short-term outcomes, operation time was significantly shorter for PG than TG (252 min versus 303 min; p < 0.0001), but there were no group-dependent differences in blood loss and postoperative complications. For long-term outcomes, incidence of reflux esophagitis in the PG group was significantly higher than that of the TG group (14.5% versus 5.4%; p = 0.02), while there were no differences in the incidence of anastomotic stenosis between the two (5.7% versus 5.4%; p = 0.92). Overall patient survival rates were similar between the two groups (3-year survival rates: 96% versus 92% in the PG and TG groups, respectively; p = 0.49). CONCLUSIONS Patients who underwent PG were better able to control weight loss without worsening the prognosis, relative to those in the TG group. Optimization of a reconstruction method to reduce reflux in PG patients will be important.

Abstract
IMPORTANCE It is unclear whether proximal gastrectomy (PG) can replace total gastrectomy (TG), even in cases of advanced gastric carcinoma. OBJECTIVES To evaluate the oncologic safety of PG based on the lymph node (LN) metastasis rate and develop a selection diagram for PG eligibility. DESIGN, SETTING, AND PARTICIPANTS In this cohort study, a retrospective analysis of a prospective database of gastric carcinoma surgery was performed including procedures that took place between December 1, 2000, and December 31, 2015, in the National Cancer Center, Korea, a high-volume carcinoma center with a structured database and accurate long-term follow-up. Among 9952 patients who underwent surgery for gastric carcinoma, 2347 underwent TG. Six-hundred fifty-five (564 in a second statistical analysis) had gastric carcinoma in the upper third of the stomach. The inclusion criteria were age 18 to 85 years, histologically proven adenocarcinoma (any size or differentiation) located in the upper third of the stomach, curative R0 TG performed, and postoperative follow-up for at least 3 years. Exclusion criteria included Borrmann type 4 carcinoma, T4 category, use of neoadjuvant chemotherapy, and a history of other carcinomas. Data analysis was performed from December 1, 2019, to May 30, 2020. EXPOSURES Total gastrectomy and LN dissection. MAIN OUTCOMES AND MEASURES The primary end point was the rate of LN metastasis at LN stations 4d, 5, and 6, which are usually not dissected during PG. RESULTS Among the 655 study patients, the mean (SD) age was 57.7 (11.9) years, and 462 (70.5%) were men. Only those with poorly differentiated cT3 category carcinomas had an increased incidence of LN metastasis at stations 4d (2 of 32 [6.3%]) and 11d (T3N0: 2 of 22 [9.1%], T3N1: 3 of 27 [11.1%]), independent of tumor size. For cT1-T3N0/1M0 category carcinomas, the incidence of station 5 LN metastasis was 0, irrespective of tumor size and differentiation. The LN metastasis rate at stations 4d and 6 for cT1-T3N0/1M0 differentiated tumors was also 0. Tumor size greater than or equal to 4.1 cm was associated with significantly increased LN metastasis compared with tumors less than 4.1 cm (40.0% vs 20.4%, P = .001). CONCLUSIONS AND RELEVANCE The findings of this study suggest that PG can be safely performed for cT1-T2N0/1M0 tumors less than 4.1 cm in diameter that are located in the upper third of the stomach. The cT3N0/1M0-differentiated tumors less than 4.1 cm may also be eligible for PG, whereas poorly differentiated cT3 tumors and any cT4 or cN2/3 diseases require TG.

Abstract
BACKGROUND To compare laparoscopic proximal gastrectomy (LPG) and laparoscopic total gastrectomy (LTG) with regard to outcomes, including efficacy and safety, in patients with proximal gastric cancer. METHODS Original English-language articles comparing LPG and LTG for proximal gastric cancer up to November 2019 were systematically searched in the Embase, PubMed, Cochrane Library, Web of Knowledge, and ClinicalTrials.gov databases by two independent reviewers. Our main endpoints were surgery-related features (operation time, blood loss, harvested lymph nodes, and postoperative hospital stay), postoperative complications (anastomotic leakage, anastomotic bleeding, anastomotic stenosis, and reflux esophagitis), and oncologic outcomes (5-year overall survival and recurrent cancer). RESULTS Fourteen studies including a total of 1,282 cases (510 LPG and 772 LTG) were enrolled. Fewer lymph nodes were harvested (WMD = -13.33, 95% CI: -15.66 to -11.00, P < 0.00001) and more postoperative anastomotic stenosis (OR = 2.03, 95% CI: 1.21 to 3.39, P = 0.007) observed in LPG than LTG. There were no significant differences in other explored parameters between the two methods. However, based on a subgroup analysis of digestive tract reconstruction, LPG with esophagogastrostomy (LPG-EG) had shorter operative time (WMD = -42.51, 95% CI: -58.99 to -26.03, P < 0.00001), less intraoperative blood loss (WMD = -79.52, 95% CI: -116.63 to -42.41, P < 0.0001), and more reflux esophagitis (OR = 3.92, 95% CI: 1.56 to 9.83, P = 0.004) than was observed for LTG. There was no difference between LPG performed with the double tract anastomosis/double-flap technique (DT/DFT) and LTG. CONCLUSION LPG can be performed as an alternative to LTG for proximal gastric cancer, especially LPG-DT/DFT, with comparable safety and efficacy.

Postoperative nutritional outcomes and quality of life-related complications of proximal versus total gastrectomy for upper-third early gastric cancer: a meta-analysis. Sci Rep 2020; 10:21460.

Abstract
Although proximal gastrectomy (PG) provides superior nutritional outcomes over total gastrectomy (TG) in upper-third early gastric cancer (EGC), surgeons are reluctant to perform PG due to the high rate of postoperative reflux. This meta-analysis aimed to comprehensively compare operative outcomes, nutritional outcomes, and quality of life-related complications between TG and PG performed with esophagogastrostomy (EG), jejunal interposition, or double-tract reconstruction (DTR) to reduce reflux after PG. After searching PubMed, Embase, Medline, and Web of Science databases, 25 studies comparing PG with TG in upper-third EGC published up to October 2020 were identified. PG with DTR was similar to TG regarding operative outcomes. Patients who underwent PG with DTR had less weight reduction (weighted mean difference [WMD] 4.29; 95% confidence interval [0.51–8.07]), reduced hemoglobin loss (WMD 5.74; [2.56–8.93]), and reduced vitamin B12 supplementation requirement (odds ratio [OR] 0.06; [0.00–0.89]) compared to patients who underwent TG. PG with EG caused more reflux (OR 5.18; [2.03–13.24]) and anastomotic stenosis (OR 3.94; [2.40–6.46]) than TG. However, PG with DTR was similar to TG regarding quality of life-related complications including reflux, anastomotic stenosis, and leakage. Hence, PG with DTR can be recommended for patients with upper-third EGC considering its superior postoperative nutritional outcomes.

Abstract
BACKGROUND Total gastrectomy and proximal gastrectomy (PG) are both surgical options for the treatment of Siewert type III adenocarcinoma of the esophagogastric junction (AEG). Currently there is no consensus on selecting which procedure to perform; in particular, there are few reports of long-term outcomes for patients with local advanced AEG. The aim of this study was to validate the usefulness of PG with double-tract reconstruction in Siewert type III AEG. METHODS The clinical data of patients with Siewert type III AEG underwent PG with double-tract reconstruction (PG-DT) or total gastrectomy with Roux-en-Y anastomosis (TG-RY) at our hospital between October 2010 and October 2018. According to the defined inclusion and exclusion criteria, 2,146 cases were enrolled in this study. A 1-to-1 propensity score matching (PSM) was performed to compare the short and long-term outcomes between the 2 groups. RESULTS The operation time was longer in the PG-DT group, and the proportion rates of complications and recovery time was similar in the 2 groups. The rates of maintaining bodyweight and free-fat mass index were significantly higher in patients who underwent PG-DT compared to those who underwent TG-RY. While complications, recovery time and survival are similar between two groups. CONCLUSIONS Regarding short-term outcomes, PG-DT seemed to be superior in terms of maintaining body weight and skeletal muscle compared to TG-RY, while both had similar complications. It was found that PG-DT enabled a potentially longer survival of pathological stage II and III Siewert type III AEG, although the finding was statistically insignificant. These results may help surgeons to determine the appropriate surgical approach and strategy for patients with early and locally advanced Siewert type III AEG.

Abstract
Purpose Proximal gastrectomy (PG) is a function-preserving surgery in cases of proximally located early-stage gastric cancer. Because gastroesophageal reflux is a major pitfall of this operation, we devised a modified esophagogastrostomy (EG) anastomosis to fix the distal part of the posterior esophageal wall to the proximal part of the anterior stomach wall to produce an anti-reflux mechanism; we named this the SPADE operation. This study aimed to show demonstrate the clinical outcomes of the SPADE operation and compare them to those of previous PG cases. Materials and Methods Case details of 56 patients who underwent PG between January 2012 and March 2018 were retrospectively reviewed: 30 underwent conventional esophagogastrostomy (CEG) anastomosis using a circular stapler, while 26 underwent the SPADE operation. Early postoperative clinical outcome-related reflux symptoms, endoscopic findings, and postoperative complications were compared in this case–control study. Results Follow-up endoscopy showed more frequent reflux esophagitis cases in the CEG group than in the SPADE group (30% vs. 15.3%, P=0.19). Similarly, bile reflux (26.7% vs. 7.7%, P=0.08) and residual food (P=0.01) cases occurred more frequently in the CEG group than in the SPADE group. In the CEG group, 13 patients (43.3%) had mild reflux symptoms, while 3 patients (10%) had severe reflux symptoms. In the SPADE group, 3 patients (11.5%) had mild reflux symptoms, while 1 had severe reflux symptoms (absolute difference, 31.8%; 95% confidence interval, 1.11–29.64; P=0.01). Conclusions A novel modified EG, the SPADE operation, has the potential to decrease gastroesophageal reflux following a PG.

Abstract
BACKGROUND Recently, the incidence of proximal early gastric cancer (EGC) has been rising rapidly. Prevalent surgical methods are proximal gastrectomy (PG) and total gastrectomy (TG); however, which method is superior remains controversial. We conducted a systematic review and meta-analysis of original articles to compare the short- and long-term clinical outcomes of PG with TG for proximal EGC. METHODS Databases, including PubMed, Embase, Web of Science, and Cochrane Library were searched up to October 2018. The Newcastle-Ottawa scale was utilized to conduct quality assessments, and publication bias was evaluated using Egger test. STATA version 14.0 was used to perform the meta-analysis. RESULTS A total of 2036 patients with proximal EGC in 18 studies were included in the meta-analysis. The results showed that PG was potentially superior to TG regarding operation time, intraoperative blood loss volume, and long-term nutritional status. Overall survival between the PG and TG groups was not significantly different. PG was associated with a high incidence of 2 kinds of postoperative complications: anastomotic stenosis and reflux esophagitis. However, the incidence of these complications associated with esophagojejunostomy with double-tract reconstruction (DTR) was comparable with that of TG. CONCLUSIONS PG has several advantages over TG for the treatment of proximal EGC, including surgical outcomes and long-term nutritional status. However, anastomotic stenosis and reflux esophagitis frequently occurred in patients undergoing PG. Esophagojejunostomy with DTR could offer a solution to reducing the incidence of these complications.

Abstract
BACKGROUND The optimal extent of lymph node (LN) dissection remains controversial in adenocarcinoma of the esophagogastric junction (AEG), especially in Siewert types II and III. The aim of this study was to analyze clinicopathological characteristics of patients with Siewert type II and III AEGs to clarify whether pyloric (no. 5 and no.6) lymphadenectomy is essential in these patients. METHODS A retrospective analysis was performed in the Third Affiliated Hospital of Soochow University from September 2008 to December 2012, and clinicopathological characteristics on all patients with Siewert type II and III AEGs, who underwent curative total gastrectomy with lymphadenectomy were collected. The index of estimated benefit from lymph node dissection (IEBLD) was used to evaluate the efficacy of lymph node dissection of no. 5 and no. 6. Both clinicopathological characteristics and IEBLDs were set as the standards in the assessment of the value of pyloric lymph nodes dissection. RESULTS A total of 216 patients with AEG (Siewert type II: 141, Siewert type III: 75) were included into the study. Type III AEG had a larger tumor size and relatively advanced T stage compared to Type II AEG. The 5-year overall survival (OS) rates in type II and type III AEGs were almost similar (type II 50.4% vs. type III 46.7%, p = 0.782). There was a very low incidence of pyloric lymph nodes metastases in type II AEG (no. 5 is 1.4% and no. 6 is 0.7%). Hence, the IEBLDs of no. 5 and no. 6 lymph node were negligible regardless of the T stage and tumor differentiation. In type III AEG, metastasis rates of no. 5 and no. 6 lymph node were 9.3 and 5.3%, respectively. The IEBLDs of no. 5 and no. 6 lymph node were 2.7 and 1.3, respectively. CONCLUSIONS Based on the IEBLDs of pyloric lymph nodes, dissection of no. 5 and no. 6 lymph nodes were worthwhile for Siewert type III AEG but not essential for Siewert type II AEG.

Abstract
BACKGROUND Total gastrectomy (TG) and proximal gastrectomy (PG) are used to treat upper-third early gastric cancer. To date, no consensus has been reached regarding which procedure should be selected. The aim of this study was to validate the usefulness of preserving the stomach in early upper-third gastric cancer. METHODS Between 2004 and 2013, 201 patients underwent PG or TG at our institution for treatment of upper-third early gastric cancer. According to the defined inclusion and exclusion criteria, 192 cases were enrolled in this study. One-to-one propensity score matching was performed to compare the outcomes between the two groups. RESULTS The operation time was shorter in the PG group. Although no significant difference was observed, the PG group had less bleeding and fewer postoperative complications. R0 resection rate was 100%, and no surgery-related deaths were observed. The frequencies of reflux symptoms and anastomotic stenosis were significantly higher in the PG group, but could be controlled by balloon dilation and drug therapy. The maintenance rates of body mass index and lean body mass were significantly higher in patients who underwent PG than TG. The total protein and serum albumin values were higher in the PG group than in the TG group and remained statistically superior. CONCLUSION PG group exhibited better perioperative performance. Furthermore, better nutritional results were obtained in the PG group. Although the late stenosis and reflux symptoms must be addressed, the PG is a preferable surgical procedure for the treatment of early proximal gastric cancer.

Short-term outcomes and nutritional status after laparoscopic subtotal gastrectomy with a very small remnant stomach for cStage I proximal gastric carcinoma. Gastric Cancer 2018; 21:500-507. [PMID: 28825149 DOI: 10.1007/s10120-017-0755-0] [Citation(s) in RCA: 46] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2017] [Accepted: 07/28/2017] [Indexed: 02/07/2023]
Abstract
BACKGROUND Total or proximal gastrectomy is usually performed for early proximal gastric carcinoma, but the optimal type of gastrectomy is still unknown. We evaluated short-term outcomes and nutritional status after laparoscopic subtotal gastrectomy (LsTG) in comparison with laparoscopic total gastrectomy (LTG) and laparoscopic proximal gastrectomy (LPG). METHODS We analyzed 113 patients who underwent LsTG (n = 38), LTG (n = 48), or LPG (n = 27) for cStage I gastric cancer located in the upper third of the stomach. Postoperative morbidities, nutritional status including body weight, serum albumin, hemoglobin, the prognostic nutritional index (PNI), and endoscopic findings at 1 year after surgery were compared between LsTG and both LTG and LPG. RESULTS Operation time and intraoperative blood loss were similar among the three groups. The incidence of postoperative morbidities was lower in LsTG than in LTG. The degree of body weight loss was significantly smaller in LsTG than in LTG at 6 and 12 months. At 12 months, LsTG resulted in better serum albumin and PNI than LPG, and better hemoglobin than LTG. Endoscopic examination demonstrated that one LsTG patient and two LPG patients had reflux esophagitis. Remnant gastritis was observed more frequently in LPG than in LsTG. No LsTG patient had bile reflux, although it was observed in four LPG patients. CONCLUSIONS LsTG with a very small remnant stomach had favorable short-term outcomes and nutritional status compared with LTG and LPG, so it may be a better treatment option for cStage I proximal gastric carcinoma.

Abstract
Laparoscopic gastrectomy is evolving. With the increasing expertise and experience of oncologic surgeons in the minimally invasive surgery for gastric cancer, the indication for laparoscopic gastrectomy is expanding to advanced cases. Many studies have demonstrated the benefits of minimally invasive surgery, including reduced risk of surgery-related injury, reduced blood loss, less pain, and earlier recovery. In order to establish concrete evidence for the suitability of minimal invasive surgery for gastric cancer, many multicenter RCTs, comparing the short- and long-term outcomes of laparoscopic versus open surgery, are in progress. Advances in laparoscopic gastrectomy are moving toward increasingly minimally invasive approaches that enable the improvement of the quality of life of patients, without compromising on oncologic safety.

Superiority of laparoscopic proximal gastrectomy with hand-sewn esophagogastrostomy over total gastrectomy in improving postoperative body weight loss and quality of life. Surg Endosc 2017; 31:3664-3672. [PMID: 28078458 DOI: 10.1007/s00464-016-5403-y] [Citation(s) in RCA: 30] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2016] [Accepted: 12/19/2016] [Indexed: 02/07/2023]
Abstract
BACKGROUND Proximal gastrectomy is not widely performed because the procedure is complicated, particularly under laparoscopy. We developed a simple laparoscopic technique of hand-sewn esophagogastrostomy with an anti-reflux mechanism. This study aimed to evaluate and compare the postoperative body weight loss (BWL) and quality of life (QOL) following laparoscopic proximal gastrectomy (LPG) and laparoscopic total gastrectomy (LTG) in patients with upper gastric cancer. METHODS We retrospectively analyzed patients with stage I upper gastric cancer undergoing LPG or LTG at Kyoto University Hospital between March 2006 and June 2014. The main outcome measures were the % BWL 1 year after gastrectomy, postoperative anastomotic stricture, and reflux esophagitis. Additionally, patient-reported outcomes were evaluated using the Post-Gastrectomy Syndrome Assessment Scale (PGSAS)-45 in patients presenting at the outpatient clinic and exhibiting no recurrence. RESULTS A total of 62 patients were included in this study (LTG, n = 42 vs. LPG, n = 20). The % BWL at 12 months in the LPG group was less than that in the LTG group (-16.3 vs. -10.7%). Multivariate analysis revealed that LPG was associated with less BWL (P = 0.003). Anastomotic stricture occurred more frequently in the LPG group than in the LTG group (0 vs. 25%). One patient in each group exhibited grade B severity of reflux esophagitis (based on the Los Angeles classification). In the questionnaire survey, LPG was better than LTG in terms of diarrhea and dissatisfaction with symptoms. In terms of reflux symptoms, patients in the LPG group experienced less acid and bile regurgitation symptoms compared with those in the LTG group. CONCLUSIONS LPG with hand-sewn esophagogastrostomy results in less postoperative BWL and better QOL than LTG despite higher rates of anastomotic stricture.
