BACKGROUND: Laparoscopic gastrectomy has become a common surgical treatment for gastric cancer in eastern Asian countries. However, a large-scale prospective study to investigate the benefit of laparoscopy-assisted distal gastrectomy (LADG) regarding long-term outcomes has never been reported. We have already reported the short-term outcomes of this study. Here we report long-term outcomes as the secondary endpoints of this study after a 5-year follow-up period. METHODS: This study comprised patients with clinical stage I gastric cancer who were able to undergo a distal gastrectomy...

OBJECTIVE: Helicobacter pylori infection is a common chronic infection that is closely associated with gastric cancer, known to be decreasing worldwide. We set up an administrative project of screening examination for H. pylori infection in junior high school students in Akita Prefecture to investigate the current prevalence of H. pylori infection in childhood in an area where the incidence of gastric cancer is particularly high. SUBJECTS AND METHODS: All students in their second or third year of junior high school (13 to 15 years old) in two cities in Akita Prefecture were recruited...

In this paper, the epidemiological and clinicobiological behavior of esophagogastric junction (EGJ) adenocarcinoma in the West is compared and contrasted to that in the East, and an overview is provided of current therapeutic strategies employed for this type of tumor in Western countries. It is well known that multimodal treatment is the therapeutic standard in locally advanced EGJ adenocarcinoma, but whether neoadjuvant/perioperative chemotherapy (CT) or neoadjuvant chemoradiotherapy (CRT) is the optimal approach is still debated...

We developed an internet e-learning system in order to improve the ability of endoscopists to diagnose gastric cancer at an early stage. The efficacy of this system at expanding knowledge and providing invaluable experience regarding the endoscopic detection of early gastric cancer was demonstrated through an international multicenter randomized controlled trial. However, the contents of the system have not yet been fully described in the literature. Accordingly, we herein introduce the contents and their principles, which comprise three main subjects: technique, knowledge, and experience...

We established a preoperative exercise and nutritional support program for elderly sarcopenic patients with gastric cancer. Twenty-two gastric cancer patients aged 65 years or older with a diagnosis of sarcopenia according to the algorithm proposed by the European Working Group on Sarcopenia in Older People received our preoperative program. The median duration of the program participation was 16 days. Total calorie and protein intakes were significantly higher after the program than before [29.4 ± 6.9 kcal/kg ideal body weight (IBW) vs 27...

BACKGROUND: Despite recent progress in systemic chemotherapy, the prognosis of gastric cancer patients with peritoneal metastasis (P1) or positive peritoneal cytology findings (CY1) is still poor. We developed a regimen combining intraperitoneal (IP) paclitaxel (PTX) with S-1 and PTX, which can produce notable efficacy with regard to peritoneal lesions. Surgery after response to combination chemotherapy is a promising option for P1 or CY1 gastric cancer. A retrospective study was performed to evaluate the safety and efficacy...

BACKGROUND: Although second-line therapy is often considered for advanced gastric cancer patients, the optimal candidates are not well defined. METHODS: We retrospectively collected baseline parameters, tumour features, and treatment data for 868 advanced gastric cancer patients exposed to multiple treatment lines at 19 Italian centres. Cross-tables and chi-square tests were used to describe categorical features. To predict the impact of clinical variables on progression-free survival and overall survival, Kaplan-Meier and Cox regression analyses were performed...

BACKGROUND AND AIM: The serological risk prediction system combines the pepsinogen test and anti-Helicobacter pylori (H. pylori) antibody determination. In this system, chronic atrophic gastritis (CAG) is diagnosed using the pepsinogen test. Patients who are H. pylori negative and pepsinogen negative are classified into group A, are assumed to be H. pylori uninfected, and are at an extremely low risk for gastric cancer. However, gastric cancers are detected in this group. The aim of this study is to clarify the clinicopathological status of group A patients with gastric cancer...

BACKGROUND: Most metastatic gastrointestinal stromal tumors (GISTs) develop resistance to the first-line imatinib treatment. Recently, increased vessel density and angiogenic markers were reported in GISTs with a poor prognosis, suggesting that angiogenesis is implicated in GIST tumor progression and resistance. The purpose of this study was to investigate the relationship between tumor vasculature and imatinib resistance in different GIST mouse models using a noninvasive magnetic resonance imaging (MRI) functional approach...

BACKGROUND: Endoscopic submucosal dissection (ESD) has become accepted as the standard treatment for early gastric cancer. However, comparative outcomes of ESD and surgery have not been evaluated for adenocarcinoma in the esophagogastric junction (EGJ). We investigated the long-term outcomes of ESD compared with those of surgery for adenocarcinoma in the EGJ. METHODS: Patients who underwent ESD or surgery for Siewert type II adenocarcinoma between 2005 and 2010 and who met the absolute and expanded criteria for endoscopic resection were eligible...

BACKGROUND: Several studies have suggested no difference in the liver function of early gastric cancer (EGC) patients with liver cirrhosis (LC) between laparoscopic and open distal gastrectomy. However, the number of patients and comparison of long-term survival rates between the two groups are limited. The purpose of this study was to compare the long-term survival and immediate postoperative liver function of EGC patients with LC after laparoscopic and open distal gastrectomy. MATERIALS AND METHODS: The clinical data of EGC patients with LC who had no other malignancy and underwent distal gastrectomy at Asan Medical Center between January 2005 and April 2013 were investigated retrospectively...

BACKGROUND: No optimal method of reconstruction for proximal gastrectomy has been established because of problems associated with postoperative reflux and anastomotic stenosis. It is also important that the reconstruction is easily performed laparoscopically because laparoscopic gastrectomy has become widely accepted in recent years. METHODS: We have developed a new method of esophagogastrostomy, side overlap with fundoplication by Yamashita (SOFY). The remnant stomach is fixated to the diaphragmatic crus on the dorsal side of the esophagus...

BACKGROUND: White globe appearance (WGA) refers to a small white lesion of globular shape underneath cancerous gastric epithelium that can be clearly visualized by magnifying endoscopy with narrowband imaging (M-NBI). WGA has been reported to be a novel endoscopic marker that is highly specific in differentiating early gastric cancer (GC) from low-grade adenoma, and has a significantly higher prevalence in early GCs than in noncancerous lesions. However, interobserver agreement in detecting WGA and whether training intervention can improve diagnostic accuracy are unknown...

BACKGROUND: Only a few studies have reported treatment options for stenosis after endoscopic submucosal dissection (ESD) for gastric neoplasms. This study aimed to identify the risk factors for and evaluate the management of stenosis after ESD for gastric epithelial neoplasms in the cardia and antrum. METHODS: We retrospectively reviewed 1218 patients (1447 gastric epithelial neoplasms) who underwent ESD at Tonan Hospital from June 2004 to November 2015. Post-ESD stenosis was defined when a standard endoscope could not be passed through the site...

BACKGROUND: Globally, Asian countries bear a disproportionate gastric cancer burden. Asian Americans, the fastest growing minority population in the US, have higher gastric cancer survival than non-Hispanic whites (NHWs) despite higher incidence. Benefitting from uniform cancer registry standards within the US, we examine for the first time the heterogeneity in the Asian American population, which may elucidate the causes of these disparities. METHODS: SEER gastric cancer data from 2000 to 2012 were used to calculate 5-year survival estimates for NHWs and the six largest Asian ethnicities...

OBJECTIVE: The aim of this study was to evaluate the prognostic significance of the intratumor stromal proportion in gastric signet ring cell (SRC) carcinomas. BACKGROUND: Cancer stroma, as exemplified by cancer-associated fibroblasts (CAFs), plays critical roles in cancer proliferation, invasion, and metastasis. METHODS: One hundred seventy-five SRC carcinoma cases were classified according to the intratumor desmoplastic stromal proportion to then analyze the clinicopathologic characteristics of stroma-rich cases...
