Levels of gastric juice nitrite, several urinary N-nitroso compounds, and other analytes were examined among nearly 600 residents in an area of Shandong, China, where precancerous gastric lesions are common and rates of stomach cancer are among the world's highest. Gastric juice nitrite levels were considerably higher among those with gastric juice pH values above 2.4 versus below 2.4. Nitrite ...
High blood homocysteine levels may risk gastric cancer. However, observational studies have been plagued by chance, bias, confounding, or reverse causality. In this study, we assessed the relationship between blood homocysteine levels and gastric cancer by using a Mendelian randomization method, which is independent of nongenetic confounding.We took 2 steps to perform Mendelian randomization an...
Although it can affect any part of the gastrointestinal system, signet ring cell carcinoma (SRC) is a common malignant entity stomach cancers. We discuss case patient who had prior history gastric adenocarcinoma with cells, for which he underwent partial gastrectomy gastro-jejunal anastomosis. Four months after surgery, presented an acute postoperative blockage. Operative findings and pathology...
Background: As far as the role and amount of Transferrin receptor 2 (TFR2), which is the transferrin receptor gene, studies have been conducted, some of which confirming its relationship with gastric adenocarcinoma. The idea behind this study was to examine changes in the TFR2 gene expression in the tumor cells of gastric adenocarcinoma and comparing with gene expression in the normal tissue ad...
BACKGROUND Helicobacter pylori is an independent risk factor for gastric cancer, and this association may be due to the bacterium causing reactive oxygen species mediated damage to DNA in the gastric epithelium. High dietary ascorbic acid intake may protect against gastric cancer by scavenging reactive oxygen species. AIMS To assess reactive oxygen species activity and damage in gastric mucos...
BACKGROUND Gastroparesis is characterized by delayed gastric emptying. This pathology is usually observed in patients with diabetes. One standard approach to quantitative assessment of gastric emptying is scintigraphic study. The aim of present study was to perform scintigraphic study of gastric emptying time in patient with diabetes and to find its correlation with patients' characteristics. ...
Families with autosomal dominant inherited predisposition to gastric cancer have been described. More recently, germline E-cadherin/CDH1 mutations have been identified in hereditary diffuse gastric cancer kindred. The need to have protocols to manage and counsel these families in the clinic led a group of geneticists, gastroenterologists, surgeons, oncologists, pathologists, and molecular biolo...
BACKGROUND Gastric cancer is a leading cause of cancer deaths worldwide but there are few data from Africa. We recently observed a trend towards diagnosis in younger patients. OBJECTIVE To test the hypothesis that HIV might have altered risk factors for acquisition of gastric cancer, in a case-control study in the University Teaching Hospital, Lusaka, Zambia. METHODS Patients (n=52) with co...
Background—Helicobacter pylori is an independent risk factor for gastric cancer, and this association may be due to the bacterium causing reactive oxygen species mediated damage to DNA in the gastric epithelium. High dietary ascorbic acid intake may protect against gastric cancer by scavenging reactive oxygen species. Aims—To assess reactive oxygen species activity and damage in gastric mucosa ...
