Background and Objectives: Cancer is the third cause of death in Iran. Gender is an important covariate for incidence of most cancers. So, epidemiological data on Gender differences related to common cancers provide good evidence in control of cancers. The aim of this study was providing population-based information on the gender differences in incidence rates and epidemiology of esophagus, s...
Background: The Micronuclei has been discussed as an indicator of chromosomal damage in radiotherapy. This study aimed to investigate the changes of micronuclei in peripheral blood lymphocytes of patients with of the gastrointestinal cancers pre- and post-chemo-radiation. Methods: This cross-sectional study was conducted in patients with gastrointestinal cancers who referred to oncology ward...
The increasing incidence of esophageal adenocarcinoma (EAC) is mirrored by the increasing prevalence of Barrett esophagus, a precursor lesion resulting in a large number of individuals "at risk" for this lethal malignancy. Among patients with Barrett esophagus, only about 0.3% annually will develop EAC. Because large numbers of patients are followed in endoscopic surveillance, there is a need f...
BACKGROUND Esophageal adenocarcinoma develops through a multistage process which is characterized histopathologically by progression from Barrett's intestinal metaplasia to Barrett's esophagus with dysplasia and ultimately to adenocarcinoma. The genetic basis of this process is increasingly well understood, but no studies have examined the role of the transcription factor c-myb in this disease....
abstract background: esophageal cancer is one of the major malignancies, with various epidemiological aspects in recent years in developing countries, including increased prevalence and variations of pathologic patterns. this may be due to increasing rates of barrett’s esophagus, gastroesophageal reflux, smoking and obesity. this study was performed from 1991 to 2005 in order to evaluate variou...
Metastasis of breast cancer to the esophagus has been reported but is rare. It is often difficult to diagnose metastases of breast cancer to the esophagus because they are often located in the submucosa and covered with normal mucosa. Although several methods have been reported in order to obtain specimens for pathological diagnosis, the adverse effects including bleeding and perforation were c...
Adenocarcinomas of the esophagus and gastric cardia have increased in incidence over the past 10-15 years in Western countries. The cause for this increase in incidence is still unknown. Our study was designed to investigate potential risk factors for adenocarcinomas of the esophagus and gastric cardia and to compare the risk profiles of a group of patients with this cancer with those having di...
CONTEXT Gastroesophageal reflux disease (GERD) is a risk factor for adenocarcinoma of the esophagus, a rare cancer whose incidence is increasing. Adenocarcinoma may develop from Barrett esophagus, a metaplastic change of the esophageal epithelium from squamous to intestinalized columnar mucosa, which is associated with chronic reflux. Some have recommended that patients with chronic reflux symp...
esophageal squamous cell carcinoma is a rather common cancer in northern iran. incidence of adenocarcinoma of esophagus has an increasing trend in iran. co-existence of both cancers in one patient is very rare. we report a middle age woman from northern iran with a typical presentation of esophageal cancer, who was found to have a dual esophageal cancer. the disease was found in the advanced st...
Barrett’s esophagus is a well-recognized precursor of esophageal adenocarcinoma. Surveillance of Barrett’s esophagus patients is recommended to detect high-grade dysplasia (HGD) or early cancer. Because of wide variation in the published cancer incidence in Barrett’s esophagus, the authors undertook a systematic review and meta-analysis of cancer and HGD incidence in Barrett’s esophagus.
