cancer stem cells (cscs) are unique subpopulations that have the capacity to drive malignant progression with renewal abilities. recently the role of some of cscs in gastric adenocarcinoma has been studied. this study was performed in order to evaluate cd44 and cd133 expressions by immunohistochemistry in 95 primary gastric adenocarcinoma and their relation to clinical and pathological paramete...
aim : in this study, we aimed to estimate one- to five-year survival rates in iranian patients with gastric cancer (gc). in addition, we preformed subgroup analyses and meta-regression to explore possible sources of heterogeneity between studies. background : according to literatures, there has been increasing attention to the long-term survival rate in patients with gc in iran. however, resu...
Introduction: Gastric cancer is the fourth most common cancer worldwide and the second leading cause of death from cancer. In recent years, advances in cancer therapy have raised the specter of developing effective agents of high-impact diseases, like gastric cancer, which remains one of the major causes of cancer deaths in the world. Recently it has been demonstrated that vanadium compounds ex...
Introduction & Objective: Gastric cancer is one of the most common cancers in Iran, and in some regions, the prevalence of this cancer is the highest among all diagnosed cancers, also it has the highest mortality rate. Concerning to different tumoral mutations that have role in prognosis and type of treatments in different cancers, this study was done to determine the association between p53 ...
background: gastric cancer (gc) is the fifth common malignant disease and the third leading cause of cancer-related mortality in the world. ardabil, a northwestern province of iran, includes the highest rate of gc within the country. helicobacter pylori (h. pylori) vaca gene plays a major role in generating and maintaining the gastric inflammatory response , which alters the enteric nervous sys...

Background: CD1d presents glycolipid antigens to invariant natural killer T (iNKT) cells. The role of CD1d in the development of peptic ulcer and gastric cancer has not been revealed, yet. Objective: To clarify the expression of alternatively spliced variants of CD1d in peptic ulcer and gastric cancer. Methods: Patients with dyspepsia were selected and divided into three groups of non-ulcer dys...
Background: Surgery, with the aid of chemotherapy and radiotherapy, is only curative chance for gastric cancer. Unfortunately, cancer had an elevated recurrence rate, primarily locally....
background: blood group antigen binding adhesin ( baba2 ) , is essential for attachment of helicobacter pylori (h. pylori) to the epithelial cell layer and is the most important adhesin of h. pylori . the prevalence rate of the baba2 gene varies in different geographic areas. the aim of this study is to determine the frequency of the baba2 gene in patients with different clinical outcomes. mate...
helicobacter pylori (h. pylori) is classified as a class i carcinogen. the low infection rate seen in developed countries (8.9%) compared with a high infection rate (52%-98%) in developing countries indicates a strong association between infection prevalence and socioeconomic status. adhesion of h. pylori to gastric epithelial cells is an important aggressive factor. one of the genes that encod...
