OBJECTIVE: Minimally invasive surgical techniques for gastric cancer are gaining more interest worldwide. Several Asian studies have proven the benefits of minimally invasive techniques over the open techniques. Nevertheless, implementation of this technique in Western countries is gradual. The aim of this systematic review is to give insight in the differences in outcomes and patient characteristics in Asian countries in comparison to Western countries. METHODOLOGY: An extensive systematic search was conducted using the Medline, Embase, and Cochrane databases...

BACKGROUND: Gastric cancer is typically diagnosed at a late stage, leading to poor prognoses. Helicobacter pylori is responsible for 70% of gastric cancers globally, and patients with this bacterial infection often present with early stages of the carcinogenic pathway such as inflammation or gastritis. Although many patients continue to progress to advanced-stage disease after antibacterial treatment, there are no follow-up screening protocols for patients with a history of H. pylori...

BACKGROUND: The optimal surgical approach for adenocarcinoma directly at the esophagogastric junction (AEG II) is still under debate. This study aims to evaluate the differences between right thoracoabdominal esophagectomy (TAE) (Ivor-Lewis operation) and transhiatal extended gastrectomy (THG) for AEG II. METHODS: From a prospective database, 242 patients with AEG II (TAE, n = 56; THG, n = 186) were included and analyzed according to characteristics and perioperative morbidity and mortality and overall survival (chi-square, Mann-Whitney U, log-rank, Cox regression)...

BACKGROUND: The prognosis of metastatic gastric cancer (GC) remains dismal, with a median survival of 10 months. Historically, primary tumor resection was not thought to confer any survival benefit. Although high-level data exist guiding treatment of metastatic GC for patients in the East, no such data exist for Western patients despite inherent ethnic differences in GC biology. METHODS: The 2006-2012 National Cancer Database was queried for adult patients with metastatic gastric adenocarcinoma...

BACKGROUND: Although magnifying endoscopy with narrow-band imaging (ME-NBI) can help identify the horizontal margin (HM) of early gastric cancer (EGC), little is known about the factors that can clarify the HM by using ME-NBI. We aimed to characterize the pathological features of lesions in which the HM was identified using ME-NBI. METHODS: The HMs of 639 differentiated-type EGCs treated with endoscopic submucosal dissection or surgery were analyzed using conventional endoscopy and ME-NBI...

BACKGROUND: Laparoscopy-assisted distal gastrectomy (LADG) for gastric cancer may prevent the loss of body weight and lean body mass resulting from reduced surgical stress in comparison to open distal gastrectomy (ODG). A multicenter phase III trial conducted by the Japan Clinical Oncology Group (JCOG0912 trial) was performed to confirm the non-inferiority of LADG to ODG for stage I gastric cancer in terms of relapse-free survival. METHODS: This study was performed as a single-institution exploratory analysis using the data of the patients from our hospital who were enrolled in the JCOG0912 phase III trial...
