Can proximal gastrectomy with double-tract reconstruction replace total gastrectomy? a meta-analysis of randomized controlled trials and propensity score-matched studies. BMC Gastroenterol 2024; 24:230. [PMID: 39044132 PMCID: PMC11267959 DOI: 10.1186/s12876-024-03323-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/18/2023] [Accepted: 07/15/2024] [Indexed: 07/25/2024] Open
Abstract
BACKGROUND According to the 5th edition of the Japanese Guidelines for the Treatment of Gastric Cancer, proximal gastrectomy is recommended for patients with early upper gastric cancer who can retain the distal half of the residual stomach after R0 resection. However, a large number of recent clinical studies suggest that surgical indications for proximal gastrectomy in the guidelines may be too narrow. Therefore, this meta-analysis included patients with early and advanced gastric cancer and compared short- and long-term postoperative outcomes between the two groups. At the same time, we only had high-quality clinical studies such as propensity score-matched studies and randomized controlled trials, which made our research more authentic and credible. METHODS Data were retrieved from PubMed, EMBASE, Medline, and Cochrane Library up to June 2023, and included treatment outcomes after proximal gastrectomy with double-tract reconstruction and total gastrectomy with Roux-en-Y reconstruction. The primary results were Early-phase complications(Anastomotic leakage, Anastomotic bleeding, Abdominal abscess, Abdominal infection, Pulmonary infection, Incision infection, Intestinal obstruction, Dumping syndrome, Pancreatic fistula), Late-phase complications(Intestinal obstruction, Anastomosis stricture, Dumping syndrome, Reoperation, Internal hernia, Incidence of endoscopic gastroesophageal reflux), Serious complications (≥ Grade III C-D score), Quality of life[Gastroesophageal reflux symptom evaluation (Visick score)(≥ III), Los Angeles classification(C or D)], Nutritional status(Hemoglobin, Receipt of vitamin B12 supplementation), Oncologic Outcomes(The 5-year overall survival rates). Secondary outcomes were surgical outcomes (Operative time, Estimated blood loss, Postoperative hospital stay, Number of harvested lymph nodes, Gas-passing, Postoperative mortality).The Cochrane risk-of-bias tool and Newcastle‒Ottawa scale were used to assess the quality of the included studies. RESULTS After screening, 11 studies were finally included, including 1154 patients. Results from the combined literature showed that total gastrectomy had a significant advantage over proximal gastrectomy with double-tract reconstruction in mean operating time (MD = 4.92, 95% CI: 0.22∼9.61 P = 0.04). However, meta-analysis results showed that Hemoglobin (MD = 7.12, 95% CI:2.40∼11.84, P = 0.003) and Receipt of vitamin B12 supplementation (OR = 0.12, 95% CI:0.05∼0.26, P < 0.00001) in the proximal gastrectomy with double-tract reconstruction group were better than those in the total gastrectomy with Roux-en-Y reconstruction group. There is no significant difference between the proximal gastrectomy with double-tract reconstruction and the total gastrectomy with Roux-en-Y reconstruction group in Early-phase complications(OR = 1.14,95% CI:0.79∼1.64, P = 0.50), Late-phase complications(OR = 1.37,95% CI:0.78∼2.39, P = 0.27), Gastroesophageal reflux symptom evaluation (Visick score)(≥ III)(OR = 0.94,95% CI:0.14∼1.07 P = 0.07), Los Angeles classification(C or D)(OR = 0.33,95% CI:0.01∼8.21, P = 0.50), the 5-year overall survival rates (HR = 1.01, 95% CI: 0.83 ~ 1.23, P = 0.89). CONCLUSION Proximal gastrectomy with double-tract anastomosis is a safe and feasible treatment for upper gastric carcinoma. However, the operating time was slightly longer in the proximal gastrectomy with double-tract group compared to the total gastrectomy with Roux-en-Y group. The two groups were comparable to the total gastrectomy with Roux-en-Y group in terms of serious complications (≥ Grade III C-D score), early-phase complications, late-phase complications, and quality of life. Although the scope of proximal gastrectomy is smaller than that of total gastrectomy, it does not affect the 5-year survival rate, indicating good tumor outcomes for patients. Compared to total gastrectomy with Roux-en-Y group, proximal gastrectomy with double-tract reconstruction had higher hemoglobin levels, lower probability of vitamin B12 supplementation, and better long-term efficacy. In conclusion, proximal gastrectomy with double-tract reconstruction is considered one of the more rational surgical approaches for upper gastric cancer.

Abstract
Gastric signet-ring cell gastric carcinoma (GSRC) is an unfavorable subtype of gastric cancer (GC) that presents with greater invasiveness and poorer prognosis in advanced stage than other types of GC. However, GSRC in early stage is often considered an indicator of less lymph node metastasis and more satisfying clinical outcome compared to poorly differentiated GC. Therefore, the detection and diagnosis of GSRC at early stage undoubtedly play a crucial role in the management of GSRC patients. In recent years, technological advancement in endoscopy including narrow-band imaging and magnifying endoscopy has significantly improved the accuracy and sensitivity of the diagnosis under endoscopy for GSRC patients. Researches have confirmed that early stage GSRC that meets the expanded criteria of endoscopic resection showed comparable outcomes to surgery after receiving endoscopic submucosal dissection (ESD), indicating that ESD could be considered standard treatment for GSRC after thorough selection and evaluation. This article summarizes the current knowledge and updates pertaining to the endoscopic diagnosis and treatment of early stage signet-ring cell gastric carcinoma.

Abstract
BACKGROUND The clinical outcomes of endoscopic submucosal dissection (ESD) for undifferentiated (UD) intramucosal early gastric cancer (EGC) compared with those of surgery, regardless of lesion size, are not well known. Furthermore, there is a concern regarding the treatment plan before and after ESD in cases of UD intramucosal EGC within expanded indications.
AIM To evaluate clinical outcomes of ESD compared with those of surgery in UD intramucosal EGC patients regardless of tumor size.
METHODS We enrolled patients with UD intramucosal EGC after ESD with complete resection or surgery from January 2005 to August 2020 who met the within or beyond expanded indications with lesion size > 2 cm (the only non-curative factor). Overall, 123 and 562 patients underwent ESD and surgery, respectively. After propensity-score matching, clinical and long-term outcomes, i.e., recurrence-free survival (RFS) and overall survival (OS), were analyzed. The multivariable Cox proportional hazard model with treatment modality and ESD indication was used to evaluate the recurrence risk.
RESULTS After matching, 119 patients each were finally enrolled in the ESD and surgery groups. The median length of hospital stay was shorter in the ESD group than surgery group (4.0 vs 9.0 days, P < 0.001). Four cases of recurrence after ESD were local recurrences, all of which occurred within 1 year. Total recurrence was seven (5.9%) and two (1.7%) in the ESD and surgery groups, respectively. No difference was observed between the two groups with respect to OS (P = 0.948). However, the ESD group had inferior RFS compared with the surgery group (P = 0.031). ESD was associated with the risk of recurrence after initial treatment in all enrolled patients (hazard ratio, 5.2; 95% confidence interval: 1.0-25.8, P = 0.045).
CONCLUSION Although OS was similar between the two groups, surveillance endoscopy was important for the ESD than for the surgery group because RFS was inferior and local recurrence was an issue.

Abstract
The risk factors have not been well-defined for prognosis in gastric signet ring cell carcinoma (GSRC) patients. This study is designed to prognosticate survival in GSRC patients by establishing and verifying a predictive model with neutrophil-lymphocyte ratio (NLR).A total of 147 GSRC patients from Department of Surgical Oncology, Neimenggu Baogang Hospital, Inner Mongolia Medical University were retrospectively reviewed. A predictive model was established using Cox proportional hazards. The performance of the model was evaluated by ROC curves.In present study, we found that overall survival (OS) (P < .001, Fig. 1A) and tumor recurrence rate (P = .036, Fig. 1B) in the NLR ≤ 2.8 group were significantly better than those in the NLR > 2.8 group. These results showed that NLR ≤ 2.8 was significant prognostic factor related with both OS and tumor recurrence in patients with GSRC. After adjusting for competing risk factors, NLR ≤ 2.8 (hazard ratio [HR]: 2.625, 95% confidence interval [CI]: 1.505-5.3166, P = .003), tumor size (HR: 3.024, 95% CI: 1.521-4.186, P = .005), and tumor metastasis (HR: 3.303, 95% CI: 1.25-4.525, P = .012) remained independent predictors of tumor recurrence rate and OS. Our results showed that comparing with the model without NLR (area under ROC curve: 0.798), the model with NLR (area under ROC curve: 0.826) had significant better predictive power than the model without NLR, which further confirmed the value of NLR in predicting prognosis of patients with GSRC.In conclusion, a high NLR value independently predicts poor survival in patients with GSRC after surgery. The NLR may help oncologists evaluate outcomes of patients received surgical resection and chemotherapy in order to choose alternative therapies for patients with high NLR value.

Abstract
Purpose There has been an increase in the incidence of signet ring cell cancer (SRCC) of the stomach and gastro-esophageal junction (GEJ). The multistage carcinogenesis involving genetic and epigenetic aberrations may have a major role in the increasing incidence of SRCC. Although there are numerous studies on the prognostic value of SRCC, they are markedly inconsistent in their results, making it impossible to draw any meaningful conclusions. We aimed to examine the available evidences on molecular alterations and stage-stratified treatment approaches in SRCC of the stomach and GEJ. Methods A systematic search was carried out in PubMed. Studies available in English related to SRCC of stomach and gastro-esophageal junction were identified and evaluated. Results This study reviewed the current evidence and provided an insight into the molecular alterations, stage-stratified treatment approaches, and future challenges in the management of SRCC of the stomach and GEJ. Specific therapeutic strategies and personalized multimodal treatment have been recommended based on the tumor characteristics of SRCC. Conclusion Multistage carcinogenesis involving genetic and epigenetic aberrations in SRCC is interlinked with stage-dependent prognosis. Specific therapeutic strategy and personalized multimodal treatment should be followed based on the tumor characteristics of SRCC. Endoscopic resection, radical surgery, and perioperative chemotherapy should be offered in carefully selected patients based on stage and prognostic stratification. Future studies in genetic and molecular analysis, histopathological classification, and options of multimodality treatment will improve the prognosis and oncological outcomes in SRCC of gastric and GEJ.

Gastric Cancer 2021; 24:888-896. [PMID: 33620603 DOI: 10.1007/s10120-021-01171-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/16/2020] [Accepted: 02/12/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUNDS The clinical significance of subepithelial (SE) spread from early gastric cancer (EGC) is poorly understood. Thus, we evaluated the proportion and extent of SE spread from EGC, as well as related risk factors. METHODS We reviewed medical records and pathological specimens from patients with EGC who underwent surgery or endoscopic resection between January 2016 and December 2016 at Chungnam National University Hospital. RESULTS A total of 404 patients were reviewed and SE spread was identified for 142 patients (35.1%). The presence of SE spread was associated with gender, histological type, location, endoscopic appearance, color change, presence of lymphovascular invasion, and invasion depth. Multivariable analysis revealed that SE spread was only independently associated with histological type. The distance of SE spread was significantly different between histological types, and the maximum distance was 17 mm. CONCLUSION More than 30% of our patients with EGC had SE spread, which could reach up to 17 mm. Given the proportion of SE spread in these cases, a wider resection margin may be safe during endoscopic resection or surgery.

Abstract
BACKGROUND Locally advanced gastric cancer (LAGC) presents a therapeutic dilemma, particularly as it often involves adjacent organs through desmoplasia or true pathologic invasion. To obtain a margin-negative resection, these tumors require en bloc gastrectomy with multivisceral resection (G+MVR), and contention remains regarding its safety and oncologic benefit. METHODS We used the National Cancer Database to retrospectively evaluate the short- and long-term outcomes of patients with LAGC treated in the USA between 2004 and 2016. Associations with margin status and perioperative outcomes were calculated using logistic regression. Survival was estimated using Cox proportional hazards regression and the Kaplan-Meier method. RESULTS Overall, 785 pathologic stage T4b (pT4b) patients diagnosed with LAGC underwent gastrectomy (n = 438) or G+MVR (n = 347). There was no association between G+MVR and short- or long-term mortality. Positive resection margins (HR 1.68, 95% CI 1.40-2.03), the presence of nodal disease (HRs 1.46-1.50), treatment at a high-volume center (HR 0.76, 95% CI 0.68-0.85), and the receipt of adjuvant chemotherapy (HR 0.64, 95% CI 0.51-0.80) were independently associated with overall survival. Diffuse-type histology was associated with higher rates of an R1 resection (OR 3.60, 95% CI 2.20-5.87). Perioperative and long-term survival metrics were comparable between patients with pT4a and pT4b LAGC who underwent a margin-negative G+MVR. Undergoing a margin-negative G+MVR imparted a 6-month survival benefit over non-curative gastrectomy alone (p < 0.001). CONCLUSIONS Our study demonstrates the safety and long-term feasibility of G+MVR for disease clearance in well-selected patients with LAGC, and we advocate for their referral to high-volume centers for optimal care.
