background: gastric cancer (gc) is one of the most common cancers in the world and helicobacter pylori (hp) infection is considered a causative factor. the aim of this study was to determine the characteristics and the associated factors of (gc) in a small cohort. methods: overall, 54 patients with diagnosed gastric cancer were followed-up at the department of gastroenterology & hepatology at b...

background: glutathione s-transferases ( gsts ) have been investigated as potential carcinoma susceptible genes. however, the relationship between gsts ( gstm1 , gstt1 ) variants and gastric carcinoma (gc) risk has been controversial in chinese population. methods: a comprehensive literature search strategy (pubmed, chinese biomedical database, chinese national knowledge infrastructure, wan fan...

PURPOSE EBV-associated gastric carcinoma shows global CpG island methylation of the promoter region of various cancer-related genes. To further clarify the significance of CpG island methylator phenotype (CIMP) status in gastric carcinoma, we investigated methylation profile and clinicopathologic features including overall survival in four subgroups defined by EBV infection and CIMP status: EBV...

background: the presence of metastatic lymph nodes is the most important prognostic factor for gastric carcinoma; however, the optimal system for the accurate staging of lymph node metastasis for patients with gastric cancer remains controversial. this study was designed to compare five systems in relation to the n classification of gastric carcinoma. materials and methods: this multicentric hi...

AIM To compare (18)F-fluorodeoxyglucose positron emission tomography/computed tomography ((18)F-FDG PET/CT) features in gastric lymphoma and gastric carcinoma. METHODS Patients with newly diagnosed gastric lymphoma or gastric carcinoma who underwent (18)F-FDG PET/CT prior to treatment were included in this study. We reviewed and analyzed the PET/CT features of gastric wall lesions, including ...

This investigation was done in Kennan from March 1989 to March 1993 to study the epidemiology of cancers in this province and to compare the results with a previous study performed in this area and some available statistics. A total number of 288 1 new cases of malignancy were registered and the crude relative frequency of cancers was studied. Gastric cancer with a frequency of 9.7%, malig...

To determine the relationship between gastric secretion and gastric carcinoma, we investigated gastric acid secretion and the fasting serum levels of pepsinogen I and gastrin in 50 Japanese patients with early gastric carcinoma. After the histological and macroscopic type of carcinoma had been determined, results were compared with findings in 50 Japanese control subjects whose gastric mucosa w...

AIM OF THE STUDY Platelet-derived growth factor B (PDGF-B), a vital growth factor which can induce angiogenesis and epithelial-mesenchymal transition (EMT), is important in the metastasis of many tumors. However, the roles of PDGF-B in gastric carcinoma are largely unknown. We investigated the correlation between PDGF-B, PDGFR-β and E-cadherin expression with the clinical features of gastric ca...
