Background and aims: Gastric malignancies have the fourth place among the most prevalent cancers. In many cancers, overexpressing of HER2/neu gene has been observed with a poor prediction. Up to now, there is a little information about the duplication of HER2/neu gene in gastric cancer using MLPA method. The present study aimed to investigate the frequency of mutations resulting from ampl...
Gastric cancer is one of the most common cancers in world. Delayed diagnosis cause death patients. Long noncoding RNAs (lncRNAs) are a group non-coding that effective incidence cancers. Studies different determined HOTAIR as an important lncRNA tumorigenesis. In gastric cancer, function initiation and progression seems to be crucial. this study, we confirmed significant differential expression ...
introduction: c - reactive protein (crp) is an acute-phase plasma protein that can be used as a marker of activation of the immune system. in response to several inflammatory reactions,the concentration of crp increases and recently have been applicated as a cancer detector in some studies. we aimed to evaluate the relation between crp level and the staging and grading of gastric and colon mali...
BACKGROUND Claudins are membrane proteins that play critical roles in tight junction (TJ) formation and function. Members of the claudin gene family have been demonstrated to be aberrantly regulated, and to participate in the pathogenesis of various human cancers. In the present study, we report that claudin-11 (CLDN11) is silenced in gastric cancer via hypermethylation of its promoter region. ...
background: population based research contributes to our understanding of cancer at many levels. for health program planning and policy making it is important to have information about the incidence of the common cancers in the population. descriptive epidemiologic studies measure the occurrence of cancer and other health-related factors in relation to person (e.g. age, sex, race, social class,...
OBJECTIVE To retrospectively analyze the qualitative CT features that correlate with human epidermal growth factor receptor 2 (HER2)-expression in pathologically-proven gastric cancers. MATERIALS AND METHODS A total of 181 patients with pathologically-proven unresectable gastric cancers with HER2-expression (HER2-positive [n = 32] and negative [n = 149]) were included. CT features of primary ...
BACKGROUND From March 1986 through May 1991, we conducted a randomized nutritional intervention trial, the General Population Trial, in Linxian, China, a region with epidemic rates of squamous esophageal and adenomatous gastric cardia cancers. We found that participants who received selenium, beta-carotene, and vitamin E had significantly lower cancer mortality rates than those who did not. In ...
The frequency of gastric cancer in patients with renal cell carcinoma (RCC) is exceptionally high in our region suggesting a common molecular basis. Our study aimed to characterize tumors and to analyze possible underlying molecular features in 12 patients with gastric cancer and concomitant RCC. We performed an immunohistochemical analysis including p53 protein expression, proliferative activi...
