Objective HER-2/neu gene is overexpressed in diverse human cancers and studies suggest a role of its product – p185 protein – in tumor progression by specifically promoting the invasive capacity of tumor cells. Our aim was to evaluate HER-2/neu content in resectable gastric cancer in this geographical region and assess the relationship between p185 expression and clinicopathologic tumor paramet...

PURPOSE Autosomal dominant hereditary diffuse gastric cancer (HDGC) is caused by germ-line E-cadherin (CDH1) gene mutations. Early detection of cancer in carriers is difficult because HDGC escapes endoscopic detection. We hypothesized that the glucose metabolism is enhanced in HDGC and that this can be detected with [18F]fluoro-2-deoxy-d-glucose positron emission tomography (FDG-PET). EXPERIM...

The management of hereditary diffuse-type gastric cancer revolves around surveillance biopsies and the timing of prophylactic gastrectomy. In the absence of a validated surveillance biopsy protocol, we modeled bioptic diagnostic yield on the basis of the topographic distribution of cancer foci in a series of 10 gastrectomies in CDH1-mutation carriers. Complete histologic examination was perform...

introduction: gastric cancer remains the second most common cause of cancer-related deaths worldwide. in many malignancies like, lung and breast, multiple prognostic factors are known, such as mutations in ki-67, her-2/neu, p53. in this study, we evaluated immunohistochemical protein expression patterns of cell-cycle-regulators p53, proliferation marker ki-67, surface expression of cd44, her-2/...

background and objective: host genetic factors such as cytokine gene polymorphisms as well as helicobacter pylori (h. pylori) infection have been found to be associated with gastric cancer risk . interleukin 1 is a pro-inflammatory cytokine involved in h. pylori-induced gastric inflammation. therefore, we analyzed the association between il-1β and il-1-rn polymorphisms and gastric cancer in per...

Several risk factors are described for gastric cancer. Helicobacter pylori infection and a family history of cancer the two main Gastric has significant geographic, ethnic, socioeconomic differences in distribution. This review article will discuss The molecular cascade events underlying colonic-type its distinct precursor lesions is not fully understood. In contrast, much more known about path...

INTRODUCTION Germline mutations in E-cadherin (CDH1) have been reported in families with early onset, diffuse gastric cancer. More recently, mutations in CDH1 have been described in colorectal cancer cell lines. AIMS We have investigated if germline mutations in CDH1 occur among different groups of Korean gastric and colorectal cancer patients, with and without a positive family history. ME...

Gastric cancer is one of the most common malignancies. DNA methylation is implicated in DNA mismatch repair genes deficiency. In the present study, we evaluated the methylation status of MLH1, MSH2, MSH6 and PMS2 in 20 diffuse- and 26 intestinal-type gastric cancer samples and 20 normal gastric mucosal of gastric cancer patients from Northern Brazil. We found that none of the nonneoplastic samp...

The disruption of tight junction protein expression in cancer might account for invasiveness, loss of cohesion, and lack of differentiation. Our cDNA array data indicated that claudin 7 was up-regulated in gastric carcinoma. We investigated the expression patterns and clinical implications of claudin 7 in gastric cancer. By immunohistochemical staining and Western blot, claudin 7 was significan...
