REVIEW
Hwoon Yong Jung
Endoscopic resection (Endoscopic mucosal resection [EMR] and endoscopic submucosal dissection [ESD]) is already established as a first-line treatment modality for selected early gastric cancer (EGC). In Korea, the number of endoscopic resection of EGC was explosively increased because of a National Cancer Screening Program and development of devices and techniques. There were many reports on the short-term and long-term outcomes after endoscopic resection in patients with EGC. Long-term outcome in terms of recurrence and death is excellent in both absolute and selected expanded criteria...

In spite of the global decline in its incidence and mortality, gastric carcinoma still remains a major cause of death due to cancer. Early detection of gastric carcinoma is expected to reduce mortality rates. The applications of measuring of pepsinogen I and pepsinogen II are useful in screening of gastric carcinoma. This cross sectional comparative study was done to find out the correlation of histopathological pattern of gastric carcinoma with serum pepsinogen I & II ratio in the Department of Pathology, Sylhet MAG Osmani Medical College, Sylhet, Bangladesh from January 2010 to December 2010...

We have previously demonstrated the ability of I-Trp to disrupt the protein-protein interaction of β-tubulin with chaperonin-containing TCP-1β (CCT-β). This caused more severe apoptosis in multidrug-resistant MES-SA/Dx5, compared to MES-SA, due to its higher CCT-β overexpression. In this study, we screened a panel of cancer cell lines, finding CCT-β overexpression in the triple-negative breast cancer cell line MDA-MB-231, colorectal cancer cell lines Colo205 and HCT116, and a gastric cancer cell line MKN-45...

Aberrant fibroblast growth factor receptor (FGFR) activation is found across a diverse spectrum of malignancies, especially those lacking effective treatments. SOMCL-085 is a novel FGFR-dominant multi-target kinase inhibitor. Here, we explored the FGFR-targeting anticancer activity of SOMCL-085 both in vitro and in vivo. Among a panel of 20 tyrosine kinases screened, SOMCL-085 potently inhibited FGFR1, FGFR2 and FGFR3 kinase activity, with IC50 values of 1.8, 1.9 and 6.9 nmol/L, respectively. This compound simultaneously inhibited the angiogenesis kinases VEGFR and PDGFR, but without obvious inhibitory effect on other 12 tyrosine kinases...

Adenocarcinoma stands the most common malignancies in the gastric carcinomas and holds a significant mortality and morbidity rates annually, due to the early vague symptoms among the population and hence the delayed presentation at advanced stages of cancer. In India the screening programs for gastric cancer has been a setback due to various logistics reasons and the data available from reporting is also not content. Our study is a review article featuring the management of gastric cancer in the Indian population...

Gastric cancer (GC) is the fourth most common cancer and the second major cause of cancer-related deaths worldwide. In our previous study, a novel and sensitive method for quantifying cell-free DNA (CFD) in human blood was established and tested for its ability to predict patients with tumor. We want to investigate CFD expression in the sera of GC patients in an attempt to explore the clinical significance of CFD in improving the early screening of GC and monitoring GC progression by the branched DNA (bDNA)-based Alu assay...

In a retrospective study performed in California, U.S.A., ca. 3% of patients with gastric intestinal metaplasia (GIM) developed gastric cancer (GC) within a median time period of 4.6 years after diagnosis of GIM. This observation stresses the importance of targeted surveillance even in regions with a low GC prevalence. Patients with alcoholic liver disease as well as survivors of colorectal and lobular breast cancer were found to be at increased risk of secondary GC. A population-based Chinese study confirmed "serologic biopsy" as a useful screening tool for stratifying the individual risk of developing GC...

Background/Aims: Although gastric cancer (GC) prevalence in the United States overall is low, there is significantly elevated risk in certain racial/ethnic groups. Providers caring for high-risk populations may not be fully aware of GC risk factors and may underestimate the potential for selective screening. Our aim was to identify knowledge gaps among healthcare providers with respect to GC. Methods: An Internet-based survey was distributed to primary care providers (PCPs) and gastroenterologists in New York City, which included questions regarding provider demographics, practice environment, GC risk factors, Helicobacter pylori, and screening practices...

Horses commonly develop gastric mucosal ulcers, similar to humans, a condition known as equine gastric ulcer syndrome (EGUS) that can lead to poor performance and lost training time and care expenses. Unlike humans, however, an infectious bacterial cause of ulcers has not been conclusively identified. Herpesviruses, while well-established causative agents of diseases such as cold sores, genital lesions, and certain types of cancer, have also been implicated in the development of a subset of gastric ulcers in humans...

Gastric cancer (GC) is a prevalent upper gastrointestinal tumor characterized by high morbidity and mortality due to imperfect screening systems and the rapid development of resistance to 5-fluorouracil (5-FU). CDGSH iron sulfur domain 2 (CISD2) has been recently regarded as a candidate oncogene in several types of tumors. It is, therefore, necessary to investigate its biological function and clinical significance in gastric cancer. In this study, the down-regulated expression level of CISD2 in GC compared with adjacent normal tissues was evaluated by quantitative RT-PCR and Western blotting...

A new series of etherification chalcone derivatives were designed and synthesized through Willimison etherification and Claisen-Schmidt condensation. Among them, compound 2-c which was given chemical name of S17, has been successfully screened out as the most potent one on gastric cancer cell line(MGC803) through the investigation for their effects against the growth of five cancer cell lines (EC109, HepG2, MCF7, MGC803, SKNSH). S17 exhibited strong anti-proliferative activity on other two gastric cancer cells (HGC27 and SGC7901), but less cytotoxicity to non-malignant gastric epithelial cells GES1...

Circular RNAs (circRNAs) are implicated in a variety of cancers. However, the roles of circRNAs in gastric cancer (GC) remain largely unknown. In the current study, circRNAs expression profiles were screened in GC, using 5 pairs of GC and matched non-GC tissues with circRNA chip. Preliminary results were verified with quantitative PCR (qRT-PCR). Briefly, total of 713 circRNAs were differentially expressed in GC tissues vs. non-GC tissues (fold change ≥ 2.0, p < 0.05): 191 were upregulated, whereas 522 were downregulated in GC tissues...
