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: Postoperative malnutrition after gastrectomy is deemed inevitable, which could have prejudicial influence on survival for gastric cancer patients. A prospective feasibility study was conducted to evaluate the efficacy of postoperative oral nutritional supplements. METHODS: Stage I-III gastric cancer patients who underwent distal or total gastrectomy received oral administration of Racol(®) NF (Otsuka Pharmaceutical Factory, Japan), a liquid enteral nutritional formula, as a supplement to regular meals...

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...

BACKGROUND: Because standard chemotherapy for advanced gastric cancer consists of oral fluoropyrimidines plus platinum as first-line therapy, with paclitaxel plus ramucirumab as the second line, irinotecan is usually positioned as third-line chemotherapy in clinical practice in Japan. METHODS: A retrospective evaluation was conducted to determine the efficacy and safety of irinotecan as third-line chemotherapy for advanced gastric cancer in patients refractory or intolerant to fluoropyrimidines, platinum, and taxanes...

BACKGROUND: The reasons for higher gastric cancer incidence rates in indigenous populations are debated. METHODS: We quantify the role of Helicobacter pylori in excess gastric cancer incidence in Māori and Pacific men in New Zealand. Age-standardized gastric cancer rate ratios for 1981-2004 were calculated in Māori and Pacific men compared with European/other men born in 1926-1940 and in 1941-1955. Rate ratios were then compared with those restricted to H. pylori prevalent populations...

BACKGROUND: The association between progression type and survival has been reported in breast cancer, but remains unclear in advanced gastric cancer (AGC). Here, this association was assessed using data obtained from an earlier randomized phase III study demonstrating the non-inferiority of S-1 plus oxaliplatin (SOX) to S-1 plus cisplatin (CS) on progression-free survival and overall survival (OS) in the first-line treatment of AGC. METHODS: A Cox regression model including two time-dependent covariates, progression with new lesions and with no new lesions, was used to determine their effect on OS in each treatment group...

BACKGROUND AND STUDY AIMS: Although the Vienna Classification recommends endoscopic resection for gastric high-grade dysplasia (HGD), many resected lesions are diagnosed as gastric cancer after endoscopic resection. This study aims to evaluate the clinical outcomes of gastric HGD identified by endoscopic forceps biopsy (EFB) after endoscopic submucosal dissection (ESD) and factors associated with discrepant results. PATIENTS AND METHODS: From December 2008 to July 2015, a total of 427 lesions diagnosed as initial HGD by EFB were enrolled...

OBJECTIVE: The indications for endoscopic submucosal dissection (ESD) in patients with early gastric cancer (EGC) have been expanded. However, the long-term outcomes of ESD remain unclear. We retrospectively investigated the long-term outcomes of ESD in patients with EGC. METHODS: We retrospectively studied patients with EGC who underwent ESD at 11 institutions between January 2003 and December 2010. A total of 6456 patients (7979 lesions) who met the absolute indications for ESD and 4202 patients (5781 lesions) who met the expanded indications for ESD were studied...

Peritoneal metastasis is the most frequent pattern of gastric cancer recurrence or metastasis and is a definitive determinant of prognosis. However, an effective means of treating peritoneal disease has not yet been established. Systemic chemotherapy has only a limited effect on peritoneal metastasis, although some progress has been shown in terms of median survival time, especially among patients with a minimal or moderate disease burden. Clinical research related to intraperitoneal administration of anticancer drugs is currently underway...

BACKGROUND: Esophagogastric junction (EGJ) carcinoma has attracted considerable attention because of the marked increase in its incidence globally. However, the optimal extent of esophagogastric resection for this tumor entity remains highly controversial. METHODS: This was a questionnaire-based national retrospective study undertaken in an attempt to define the optimal extent of lymph node dissection for EGJ cancer. Data from patients with EGJ carcinoma, less than 40 mm in diameter, who underwent R0 resection between January 2001 and December 2010 were reviewed...

OBJECTIVES: Siewert type II esophagogastric junction adenocarcinoma encompasses both gastric cardia adenocarcinoma (GCA) and Barrett's esophageal adenocarcinoma (BEA) due to short-segment Barrett's esophagus. We compared these two types of Siewert type II esophagogastric junction adenocarcinoma in terms of background factors and clinical outcomes of endoscopic submucosal dissection (ESD). METHODS: We enrolled 139 patients (142 lesions) who underwent ESD from 2006 to 2014 at our institution...

BACKGROUND: There is no evidence that strict follow-up using cross-sectional imaging after curative gastrectomy benefits survival; however, nonperitoneal recurrence detected early might be treated with additional surgery. The present study examined whether early detection of recurrence by imaging modalities could increase survival, particularly in patients with nonperitoneal recurrence. METHODS: We retrospectively analyzed 218 patients with recurrent gastric cancer after curative gastrectomy performed from 2002 to 2014...

Among advanced gastric cancer cases, peritoneal dissemination is a life-threatening mode of metastasis, and any strategy to control peritoneal metastasis will significantly improve treatment outcomes. Since intraperitoneal administration of anticancer drugs can induce an extremely high concentration of drugs in the peritoneal cavity, intraperitoneal chemotherapy would appear to be a reasonable and promising strategy to control the peritoneal dissemination. However, it has been reported in the past that intraperitoneal administration of mitomycin C or cisplatin resulted in no significant clinical effects against peritoneal metastasis of gastric cancer...

Helicobacter pylori (H. Pylori) is known as the most important cause of gastric cancer. The prevalence of H. pylori infection varies widely by geographic area, age, and socioeconomic status. In Japan, H. pylori infection has been highly correlated with the incidence rate of gastric cancer, and a reduction in H. pylori infection is therefore crucial for decreasing the incidence of gastric cancer, especially at the population level. Infection occurs during childhood, commonly before 5 years of age. In Japan, where gastric cancer has ranked as the most common cancer by incidence and mortality for the last several decades, the prevalence of H...

BACKGROUND: Gastrectomy with systemic lymphadenectomy is the standard of care for resectable gastric cancer (GC), but it is sometimes associated with postoperative morbidity. Predicting complications is therefore an essential part of risk management in clinical practice. The renal function is routinely evaluated before surgery by blood examinations to determine dose of medication and infusion. However, the value of various parameters of renal function in prediction of postoperative complications remain unclear...

Methodology for the diagnosis and staging of early gastric cancer (EGC) has improved in Japan since the development of the gastro-camera and determination of a definition of EGC. Imaging technology has been steadily evolving in the endoscopy field. Improvements in the resolution of standard endoscopy images used in screening and surveillance provide greater opportunities to find gastric cancer earlier. Image enhancement endoscopy (IEE), such as narrow band imaging (NBI), highlights mucosal structures and vascularity...

BACKGROUND: Gastric "crawling-type" adenocarcinoma (CRA) is a tumor histologically characterized by irregularly fused glands with low-grade cellular atypia that tends to spread laterally in the mucosa. To date, the expression characteristics of the key molecules involved in CRA, including receptor tyrosine kinases (RTKs), mismatch repair (MMR) proteins, phosphatase and tensin homolog (PTEN), as well as the Epstein-Barr virus (EBV) status, have yet to be uncovered. METHODS: We constructed tissue microarrays of 94 CRAs, 72 conventional-type differentiated adenocarcinomas (CDAs), and 71 intramucosal poorly cohesive adenocarcinomas (PCAs) from early gastric cancers to evaluate and compare the pathological and expression profiles of potential key molecules for molecular classification (EBV; four MMR proteins-MLH1, MSH2, PMS2, and MSH6; three RTKs-HER2, MET, and EGFR; PTEN; and p53)...
