abstract background and objective: baba2 and hpa genes are involved in adherence of helicobacter pylori (h.pylori) to gastric mucosal tissue. this study aimed to investigate the frequency of these genes in isolates of h. pylori from gastric biopsies and their relationship with gastritis, peptic ulcer and gastric cancer. methods: gastric biopsy samples were obtained from patients wit...
BACKGROUND This study aimed to detect hypermethylation in serum DNA from patients with gastric cancer at various stages and to assess the assay for early detection of primary and recurrent disease. MATERIALS AND METHODS Preoperative serum samples were obtained from 109 patients with gastric cancer. Blood samples were subjected to methylation-specific polymerase chain reaction analysis to dete...
gastric cancer is the most common gi cancer. it has a very high incidence rate in the northeastern iran.contrary to western countries and japan, the incidence of gastric cancer has been increasing in iran during the past two decades. helicobacter pylori infection is the most important risk factor for developing gastric cancer. however, the presence and influence of other environmental and genet...
Background and purpose: Gastric carcinoma is the second leading cause of cancer death worldwide and its incidence varies considerably according to geographical location. There are multiple etiologic factors such as infection with ËBV that play a role in carcinogenesis of gastric cancer, yet there is not enough evidence about pathogenesis of ËBV and its relationship with gastric cancer. Thus, ...
Abstract Background and Aim: Gastric cancer is one of the most common malignancies in the world. Genetic background is known to be one of the risk factors for gastric cancer. One of the genes that have been shown to be involved in various cancers, including gastric cancer, is the MCC gene. There are many SNPs in the MCC gene in the encoding and regulatory regions, one of which is rs9122, which ...
PURPOSE Titanium silicate (TS)-1 chemotherapy has been widely used against gastric cancer in Japan. The aim of the present study was to assess the efficacy and hematological safety of TS-1 as treatment for advanced and recurrent gastric cancer. METHODS From September 2006 to February 2011, 51 advanced or recurrent gastric cancers were treated with TS-1. One course of treatment consisted of 40...
Background and purpose: Gastric cancer is the most common cancer associated with high mortality worldwide. One of the genes that is down-regulated in gastric cancer, is the SIRT3 that encodes the histone deacetylase enzyme. There is a variable number tandem repeat (VNTR) polymorphism in the intron 5 of SIRT3 gene and evidence shows that expression of SIRT3 gene increases by increase in the numb...
Despite the global decline in the incidence and mortality of gastric cancer, it remains one of the most common malignant tumors of the digestive system. Although surgical resection is the preferred treatment for gastric cancer, chemotherapy is the preferred treatment for recurrent and advanced gastric cancer patients who are not candidates for reoperation. The short overall survival and lack of...
