Kita-Kyushu lung cancer antigen-1 (KK-LC-1) is a cancer/testis antigen (CTA) and predominant target for cancer immunotherapy. Our previous study indicated that KK-LC-1 was expressed in 82% of gastric cancers, and also in 79% of early stage of gastric cancers, with a correlation to Helicobacter pylori (H. pylori) infection. In addition, we found that KK-LC-1 was occasionally expressed at non-tumour sites of stomachs carrying tumours. Here, we investigated the characteristics of KK-LC-1 expression at non-tumour sites and the clinical utility of these phenomena...

A 74-year-old man was referred to our hospital for further investigation of a cystic lesion in the pancreatic body, which had been detected by ultrasonography at a local hospital. He was diagnosed as intraductal papillary mucinous neoplasm(IPMN) and further preoperative examinations were conducted. Upper gastrointestinal endoscopy demonstrated a type 0-II c tumor of the greater curvature in the upper third of the stomach. Endoscopic ultrasonography showed no sign of submucosal invasion. Endoscopic submucosal dissection(ESD)was carried out and pathological examination of a specimen revealed well differentiated adenocarcinoma with submucosal invasion, which fulfilled the indication for additional gastrectomy with lymph node dissection...

A 78-year-old woman was diagnosed with a gastrointestinal stromal tumor(GIST)of the stomach, gradually increasing from 5 years prior. The tumor was suspected to invade the pancreatic body tail and spleen, as observed with computed tomography. Because the patient refused to undergo resection, we administered imatinib mesylate for 6 years. Since early rectal cancer was revealed, the patient was referred for resection and underwent laparoscopic low anterior resection and partial gastrectomy. Histopathologically, the tumor was replaced by tissues with myxomatous changes, and no viable tumor cells were detected...

When injected, indocyanine green (ICG) immediately combines with lipoproteins to fluoresce. Here, we studied whether ICG fluorescence is effective for endoscopic marking in gastric cancer surgery using a photodynamic eye (PDE) camera and fluorescent endoscope. An ICG solution was endoscopically injected into the submucosal layer of the gastric tumor 3 days before surgery. We observed the lesions using both a PDE camera and a fluorescent endoscope during laparotomy and laparoscopy, respectively;we also observed the fluorescent luminance and fluorescent size of the resected lesions...

Patients with gastric ulcer (GU) have a significantly higher risk of developing gastric cancer (GC), especially within 2 years after diagnosis. The main way to improve the prognosis of GC is to predict the tumorigenesis and metastasis in the early stage. The objective of this study was to demonstrate the ability of human plasma amino acid metabolic profile for discriminating GC and GU. In this study, we first used liquid chromatography-tandem mass spectrometry technique to characterize the plasma amino acid metabolism in GC and GU patients...

"Crawling type" gastric cancer (GC) is known as a rare variant of early GCs, which is difficult to diagnose at an early stage because of low-grade nuclear atypia and a morphology mimicking intestinal metaplasia. This is a case report of a 69-year-old woman who was diagnosed with early-stage gastric cancer. She had endoscopic submucosal resection (ESD) and histologically, both horizontal and vertical margins were negative. Seven months after ESD, a new lesion of the stomach was detected by follow-up gastroscopy...

There is no consensus on follow-up after gastric surgery for cancer, nor evidence that it improves outcomes. We investigated the impact of intensity of follow-up, comparing the regimens adopted by two centres, in Italy and in the UK. Patients who underwent surgery for gastric and junctional type-3 adenocarcinoma, between September 2009 and April 2013, at the Surgical Clinic, University of Brescia (Italy), and at the Department of Upper Gastrointestinal Surgery, University College London Hospital (UK), were identified...

Disease breathomics is gaining importance nowadays due to its usefulness as non-invasive early cancer detection. Mass spectrometry (MS) technique is often used for analysis of volatile organic compounds (VOCs) associated with cancer in the exhaled breath but a long-standing challenge is the uncertainty in mass peak annotation for potential volatile biomarkers. This work describes a cross-platform MS strategy employing selected-ion flow tube mass spectrometry (SIFT-MS), high resolution gas chromatography-mass spectrometry (GC-MS) retrofitted with electron ionisation (EI) and GC-MS retrofitted with positive chemical ionisation (PCI) as orthogonal analytical approaches in order to provide facile identification of the oxygenated VOCs from breath of cancer patients...

miRNAs are among the novel biomarkers that can be evaluated for sensitive and early cancer diagnosis. In the present study, an electrochemical nanobiosensor has been fabricated to detect two gastric cancer (GC) related miRNAs simultaneously. By employing Au nanoparticles- and CdSe@CdS quantum dots-contained magnetic nanocomposites as electrochemical labels along with the polythiophene/reduced graphene oxide-modified carbon electrodes, this dual signal nanobiosensor showed a considerable performance in quantifying miR-106a (a GC oncogenic miRNA) and let-7a (a GC tumor suppressor miRNA)...

BACKGROUND: Patients with early gastric cancers that are limited to gastric mucosa or submucosa usually have an advanced loss of mucosal glandular tissue (glandular atrophy) and are at high risk for subsequent (metachronous) development of new gastric cancer. The long-term effects of treatment to eradicate Helicobacter pylori on histologic improvement and the prevention of metachronous gastric cancer remain unclear. METHODS: In this prospective, double-blind, placebo-controlled, randomized trial, we assigned 470 patients who had undergone endoscopic resection of early gastric cancer or high-grade adenoma to receive either H...

Bleeding of an aberrant right subclavian artery following transthoracic en bloc esophagectomy and intrathoracic gastric reconstruction is a rare but severe complication in esophageal surgery. Preoperative diagnosis can be achieved by computed tomography or magnetic resonance angiography (MRA). Various treatment options are available; thus, the treatment can be challenging and should be adjusted to the severity of the symptoms. Bleeding of an aberrant right subclavian artery can result from perioperative vascular injury or various postoperative complications...

MicroRNA-196a (miRNA-196a) is associated with the development of gastric cancer and metastasis. Intestinal metaplasia and low- or high-grade dysplasia are considered to be precursors of intestinal type gastric cancer. Accordingly, we investigated the expression of plasma miRNA-196a as an early detection biomarker in precancerous gastric lesions and early cancer (pT1a/b), which is otherwise treated with endoscopic submucosal dissection. Our data showed that levels of circulating (plasma) miRNA-196a were higher in patients with precancerous lesions/early gastric adenocarcinoma than in healthy controls...

INTRODUCTION AND AIMS: Gastric cancer is one of the main causes of cancer worldwide, but there is currently no global screening strategy for the disease. Endoscopy is the screening method of choice in some Asian countries, but no standardized technique has been recognized. Systematic alphanumeric-coded endoscopy can increase gastric lesion detection. The aim of the present article was to compare the usefulness of systematic alphanumeric-coded endoscopy with conventional endoscopy for the detection of premalignant lesions and early gastric cancer in subjects at average risk for gastric cancer...
