There are two phases of fore-stomach development during the first 200 days of pouch life in tammar wallaby. For the first 170 days, the mucosa displays an immature gastric glandular phenotype that changes to a cardia glandular phenotype, which remains for the rest of the animal's life. During this 200-day period after birth, the pouch young (PY) is dependent on maternal milk, which progressivel...
BACKGROUND The mutations in p53 gene and accumulation of p53 protein are the most common genetic events in gastric carcinomas. The present study was conducted to compare the frequency of p53 gene overexpression in a consecutive series of adenocarcinomas arising from the cardia and the antrum. This study also evaluates the associations of this gene expression with demographic and clinicopatholog...
The association between oral bisphosphonate use and upper gastrointestinal cancer has been controversial. Therefore, we examined the association with esophageal and gastric cancer within the Kaiser Permanente, Northern California population. A total of 1,011 cases of esophageal (squamous cell carcinoma and adenocarcinoma) and 1,923 cases of gastric adenocarcinoma (cardia, non-cardia and other) ...
BACKGROUND The incidence of esophageal adenocarcinoma has increased markedly in recent decades in many countries. Obesity is a potential risk factor, although the results of individual studies differ. We did a systematic review and statistical synthesis of studies that evaluated the association between body mass index (BMI) and the risk of esophageal adenocarcinoma or the adjacent gastric cardi...
Background: Saliva has a high nitrite concentration, derived from the enterosalivary recirculation of dietary nitrate, and is the main source of nitrite entering the acidic stomach. Acidification of nitrite in the presence of secondary amines or amides generates potentially carcinogenic N-nitroso compounds. The reaction is inhibited by ascorbic acid and catalysed by thiocyanate. Aim: To determi...
gastric cardia cancer; the most common type of upper gastrointestinal cancer in ardabil, iran.
BACKGROUND Dietary factors are thought to have an important role in gastric and esophageal carcinogenesis, but evidence from cohort studies for such a role is lacking. We examined the risks of gastric cancer and esophageal adenocarcinoma associated with meat consumption within the European Prospective Investigation Into Cancer and Nutrition (EPIC) cohort. METHODS A total of 521,457 men and wo...
OBJECTIVE To compare the frequency and spectrum of p53 gene mutations in adenocarcinomas of the esophagus and cardia and to compare clinical and pathologic features in patients with p53 mutant and nonmutant cancers. SUMMARY BACKGROUND DATA The p53 gene is commonly mutated in human cancers, and a p53 mutation is reported to be present in more than 50% of esophageal adenocarcinomas. Although ma...
Adenomas of the stomach are histologically classified into tubular and villous adenomas, mixed (tubulovillous) and papillary phenotypes being also recognized. They are localized in the antrum and the body. In a previous work we reported a case of serrated adenoma of the cardia having, at the time of diagnosis, an invasive growth. In this communication we report five newly identified cases of se...
Achalasia cardia is a neuromuscular disorder of unknown etiology involving the body of the esophagus and lower esophageal sphincter (LES). It is characterized by aperistalsis of the body of the esophagus and failure of relaxation of lower esophageal sphincter. It usually affects patients between the ages of 30 and 60 years. It is unusual in childhood and extremely rare in infants. We report two...
