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: in this study we evaluated the prognostic impact of metastatic lymph node ratio (mlr) in patients with gastric cancer undergoing curative surgical resection. methods: a total of 121 patients with gastric adenocarcinoma undergoing curative r0 surgical resection in our institutions between 2003 and 2010 were included in this study. mlr was classified into 3 groups as follows: mlr0; 0...
Background: The incidence rate of gastric cancer in Western countries has shown a remarkable decline in recent years although it is still the almost common cancer between men in Iran. The proto-oncogene MYC, located at 8q24.1, regulates almost 15% of human genes and is activated in 20% of all tumors. MYC amplification and overexpression of its protein product are observed in 15-30% of gastric n...
Background and aims: Gastric cancer is one of the most common cancers all over the world and is the world's second fatal cancer. This study was done to identify the epidemiological features and risk factors of gastric cancer in different regions of Birjand. Such study can be an effective step in preventing, controlling and curing the diseases. Methods: Th...
Introduction: Gastric cancer is the fourth most common cancer worldwide and the second leading cause of death from cancer. Given that existing treatments for it, but the high cost and side effects, have not demonstrated full efficacy and rely on traditional medicine and medicinal plants due to the antioxidant activity of Provskia abrotanoides, this study was performed to investigate the effects...
aim : the aim of this study is to evaluate the polymorphism in bax gene and its association with some clinical pathology traits in gastric cancer. background : gastric cancer is considered as the fourth most common cancer in the north and northwest of iran. bcl2 family has a key role in regulation of apoptosis, and any changes in the expression of bcl2 lead to cancer. patients and methods : b...
abstract objective: to determine the prevalence of helicobacter pylori (h. pylori) infection in patients with gastrectomy for gastric cancer. material and methods: samples from 95 (69 males, 26 females) consecutive patients who had undergone surgery for gastric cancer were included in this study. histologic examination of tumor obtained at the time of surgery yielded the diagnosis and then th...
objective(s):previous studies demonstrate that changes in pre-mrna splicing play a significant role in human disease development. furthermore, many cancer-associated genes are regulated by alternative splicing. there are mounting evidences that splice variants which express predominantly in tumors, have clear diagnostic value and may provide potential drug targets. located on the x chromosome, ...
nf-κb pathway is a link between inflammation and cancer and is involved in cellular responses to different stimuli. gastrointestinal lumen is exposed to many inflammatory agents such as foods, free radicals and bacterial or viral antigens. the aim of the present study was to evaluate the possible role of nf-κb1in gastric adenocarcinoma. to detect the relative level of nf-κb1transcript, total rn...
