BACKGROUND Barrett's esophagus is often asymptomatic and only a small portion of Barrett's esophagus patients are currently diagnosed and under surveillance. Therefore, it is important to develop risk prediction models to identify high-risk individuals with Barrett's esophagus. Familial aggregation of Barrett's esophagus and esophageal adenocarcinoma, and the increased risk of esophageal adenoc...
A clinical, radiological, histological, and geographical study of carcinoma of the esophagus in Kenya is reported. It was found that this cancer is diagnosed more often in males than in females, with a ration of 8:1 (Kenya Cancer Registry). The most common age in males and females is 50 to 59 years. The regions of the esophagus most commonly involved are the middle and lower thirds, in almost e...
Background : Cancer is the second most common cause of death in developed countries. The incidence of the different histological types of cancer varies greatly between different populations and it is attributed to occupational, social, cultural, racial, (possibly hereditary), and geographic influences. The objective of this study was to determine the pattern of age distribution and the frequenc...
Epidemiological data indicate that 5.8% of cancer deaths world-wide are attributable to alcohol consumption. The risk of cancer is higher in tissues in closest contact on ingestion of alcohol, such as the oral cavity, pharynx and esophagus. However, since ethanol is not mutagenic and the carcinogenic metabolite of ethanol (acetaldehyde) is mostly produced in the liver, it is not clear why alcoh...
This is a review of the epidemiologic literature on alcohol and risks of various cancers. Alcohol has consistently been related to risks of squamous cell carcinomas of the mouth, oral pharynx, larynx, and esophagus in multiple studies of varying design. The joint effects of alcohol and smoking are greater than additive, and are probably multiplicative, suggesting biological synergism. All major...
Cancer is a critical health threat in the world. It has an ongoing increasing trend.The aim of this study was to describe the trend, most common types of cancer and the gender ratio of cancer in Iran and its provinces. We searched PubMed, Google Scholar, Scopus, and Science directs from 2000 to 2017 using Keywords including “Cancer”, “Neoplasms”, “Malignancy”, “Tumor”, “Incidence”, “Epidemiolog...
Background: Cancer as the second leading cause of death following cardiovascular diseases has always been a threat to human life and due to its peculiar nature and lack of a favorable treatment, it is considered as a research priority in all communities. Understanding the geographical distribution of the incidence of various tumors, constitutes the first step in health and treatment planning. T...
