CONTEXT: -CDH17, which is expressed in the intestinal epithelium, is a novel oncogene involved in tumor invasion and metastasis. A panel consisting of cytokeratin (CK) 7, CD20, and CDX2 antibodies is typically used to diagnose gastrointestinal adenocarcinomas. However, studies have shown that CDH17 is a highly specific marker for gastrointestinal adenocarcinoma and may be important in clinical diagnosis. OBJECTIVE: -To evaluate the sensitivity and specificity of CDH17, CK20, and CDX2 antibodies in neoplastic tissues, with emphasis on colon, stomach, and esophageal gastrointestinal lineage...

: An increase in the incidence of second primary cancers (SPC) is the late effect of greatest concern that could occur in differentiated thyroid carcinoma (DTC) patients treated with radioactive iodine (RAI). The decision to treat a patient with RAI should therefore incorporate a careful risk-benefit analysis. The objective of this work is to adapt the risk estimation models developed by the Biological Effects of Ionizing Radiation Committee (BEIR VII) to local epidemiological characteristics, to assess the carcinogenesis risk from radiation in a population of Brazilian DTC patients treated with RAI...

We reported a case of human epidermal growth factor receptor 2(HER2)-positive advanced gastric cancer with multiple liver metastases that responded well to a combination of trastuzumab, capecitabine, and cisplatin(T-XP therapy)as first-line chemotherapy. A 73-year-old man was admitted to our hospital in December 2012 for liver dysfunction. Based on computed tomography(CT)and gastroendoscopy findings, he was diagnosed with advanced gastric cancer with multiple liver metastases. Because HER2 protein overexpression was observed in the primary tumor, he was treated with T-XP therapy...

A 64-year-old woman was diagnosed with advanced gastric cancer with solitary liver metastasis. Although the HER2 status of the tumor was IHC2+, no further examination for HER2 status using FISH was performed. Four courses of S-1 and cisplatin chemotherapy were administered. The primary lesion and metastatic lesion were confirmed to have partially regressed. After 4 courses of chemotherapy, an open total gastrectomy, D2 dissection, pancreatosplenectomy, and posterior segmental hepatectomy were performed. Her postoperative course was uneventful...

BACKGROUND: A sarcoid reaction is a phenomenon characterized by histologically proven granulomatous lesions without evidence of sarcoidosis. This pathology is a benign tumor itself, but several reports have described sarcoid reactions accompanying malignant tumors. Sarcoid reactions occur in various cancers, such as skin, lung, ovary, stomach, and breast cancers. However, only a few published reports have described sarcoid reactions in patients with colorectal cancer. CASE PRESENTATION: A 76-year-old woman underwent laparoscopic sigmoidectomy for sigmoid colon cancer...

Excessive dietary salt (sodium chloride) intake is associated with an increased risk for hypertension, which in turn is especially a major risk factor for stroke and other cardiovascular pathologies, but also kidney diseases. Besides, high salt intake or preference for salty food is discussed to be positive associated with stomach cancer, and according to recent studies probably also obesity risk. On the other hand a reduction of dietary salt intake leads to a considerable reduction in blood pressure, especially in hypertensive patients but to a lesser extent also in normotensives as several meta-analyses of interventional studies have shown...

BACKGROUND: and study aim: Endoscopic submucosal dissection (ESD) is a useful method for complete resection of early gastric cancer (EGC). However, there are still some cases that underwent additional gastrectomy after ESD because of non-curative resection. There is no model that can accurately predict non-curative resection of ESD. We aimed to create a model for predicting non-curative resection of ESD in patients with EGC. PATIENTS AND METHODS: We reviewed the medical records, including all gross findings of EGC, of patients who underwent ESD for EGCs...

In Korea, proximal gastrectomy has recently attracted attention as a better choice of function-preserving surgery for proximal early gastric cancer than total gastrectomy. Of the various strategies to overcome reflux symptoms from remnant stomach, double tract reconstruction not only reduces the incidence of anastomosis-related complications, but is also sufficiently reproducible as a laparoscopic procedure. Catching up with the recent rise of single-port laparoscopic surgeries, we performed a pure single-port laparoscopic proximal gastrectomy with DTR...

Phlegmonous gastritis is a rare and rapidly progressive bacterial infection of the stomach wall, with a high mortality rate. Antibiotics with or without surgical treatment are required for treatment. We present a case in which phlegmonous gastritis occurred during the diagnostic evaluation of early gastric cancer. The patient showed improvement after antibiotic treatment, but attempted endoscopic submucosal dissection failed because of submucosal pus. We immediately applied argon plasma coagulation since surgical resection was also considered a high-risk procedure because of the submucosal pus and multiple comorbidities...

The Hedgehog (Hh) signaling pathway not only plays a key part in controlling embryonic development, but in the adult stomach governs important cellular events such as epithelial cell differentiation, proliferation, gastric disease, and regeneration. In particular, Sonic Hedgehog (Shh) signaling has been well studied for its role in gastric physiology and pathophysiology. Shh is secreted from the gastric parietal cells and contributes to the regeneration of the epithelium in response to injury, or the development of gastritis during Helicobacter pylori infection...

Background and study aims: In the Western world, gastric cancer (GC) usually presents at an advanced stage, carrying a high mortality rate. Studies have reported that 14 % to 26 % of GCs are missed at endoscopy up to 3 years before diagnosis. Systematic Alphanumeric Coded Endoscopy (SACE) has been proposed to improve quality of esophagogastroduodenoscopy (EGD) by facilitating a complete examination of the upper gastrointestinal tract. This prospective cross-sectional study was designed to determine the frequency of gastric intraepithelial neoplasia (GIN) by using the SACE approach in cohort of patients from low socioeconomic level...

Background and study aims: Colon capsules display images from the moment they are ingested, making the study of other extracolonic areas possible. The aim of this study was to analyze the significance of these extracolonic findings. Patients and methods: In this single-center, prospective study, 165 patients underwent colon capsule endoscopy (CCE) between September 2009 and October 2012 to rule out colonic pathology. Images were recorded, without interruptions, from the moment the capsule was ingested until its battery ran out...

INTRODUCTION: In the U.S., people of different races/ethnicities have differences in cancer incidence, mortality, survival, stage at diagnosis, and receipt of treatment, resulting in variances in cancer burden. The burden of cancer in 2011 was assessed by race/ethnicity for 24 cancers using disability-adjusted life years (DALYs). METHODS: In 2014-2015, DALYs and their two components were estimated (years of life lost [YLLs] and years lived with disability) by race/ethnicity using population-based cancer registry data collected in 2013, vital statistics, and literature reviews...

The attribution of stochastic effects to exposure to ionizing radiation has been qualitatively discussed by introducing two distinct concepts of provability and probability. This study aims to develop a method of quantitatively assessing the provability of radiation-related cancers. To this end, the 'minimum provable dose' (MPD) was developed and applied to actual cancer mortality in Japan. The background lifetime risk of cancer mortality was calculated for the esophagus, stomach, colon, liver, lungs, skin, breasts, ovaries, bladder, and bone marrow as well as the age-specific risk coefficients reproducing those given in the 2007 Recommendations of the International Commission on Radiological Protection (ICRP)...

BACKGROUND: Stomach cancer is the second most commonly diagnosed cancer in Korea. Although the long-term survival outcome has improved, secondary primary tumors from periampullary regions are increasing inevitably and pancreaticoduodenectomy (PD) following gastrectomy is challenging. This study evaluates the surgical outcomes of PD following gastrectomy and suggests the optimum method for reconstruction. METHODS: Patients who underwent curative PD with a history of gastric resection between 2005 and 2015 were assessed retrospectively...

Solid tumor is generally observed in tissues of epithelial or endothelial cells of lung, breast, prostate, pancreases, colorectal, stomach, and bladder, where several genes transcription is regulated by the microRNAs (miRNAs). Argonaute (AGO) protein is a family of protein which assists in miRNAs to bind with mRNAs of the target genes. Hence, study of the binding mechanism between AGO protein and miRNAs, and also with miRNAs-mRNAs duplex is crucial for understanding the RNA silencing mechanism. In the current work, 64 genes and 23 miRNAs have been selected from literatures, whose deregulation is well established in seven types of solid cancer like lung, breast, prostate, pancreases, colorectal, stomach, and bladder cancer...

Homeobox genes, including HOX and non-HOX genes, have been identified to be expressed aberrantly in solid tumors. In gastrointestinal (GI) cancers, most studies have focused on the function of non-HOX genes including caudal-related homeobox transcription factor 1 (CDX1) and CDX2. CDX2 is a crucial factor in the development of pre-cancerous lesions such as Barrett's esophagus or intestinal metaplasia in the stomach, and its tumor suppressive role has been investigated in colorectal cancers. Recently, several HOX genes were reported to have specific roles in GI cancers; for example, HOXA13 in esophageal squamous cell cancer and HOXB7 in stomach and colorectal cancers...

 The present study was conducted to establish pharmaceutical intervention guidelines to enable hospital pharmacists to provide optimal pharmacotherapy to cancer patients. Many patients who use oral anticancer agents showed favorable drug compliance but insufficient drug adherence. It was demonstrated that in order to improve drug adherence, it is important to conduct interventions tailored to the patients' conditions so as to encourage interest in their medications, as well as to gain their understanding on the necessity and the side effects of their medications...
