Golestan Cohort Study
Initiatives
-
This cohort study is evaluating the environmental and genetic risk factors for esophageal squamous cell carcinoma (ESCC) in Golestan Province, Iran.
The primary aims of the GCS are:
* To identify risk factors for oesophageal cancer (OC) by a comprehensive assessment of ethnicity, occupational history, socio-economic status, past medical history, family history of cancers, gastrointestinal symptoms and signs, tobacco, opium and alcohol use, oral health, anthropometric characteristics, physical activity and tea drinking habits, including tea temperature. Nutritional patterns are also evaluated
* To establish biospecimen banks for blood, urine, hair and nail samples to be used in molecular and genetic studies of cross-sectional or nested case–control design.
* To provide a model for population-based studies in a country in economic and social transition based on collaboration between local health workers, local health authorities, national research centres, national government and international research institutions.
*Note: All published information has been collected from the article referenced in the Marker Paper box below. Therefore, there may be variations with more advanced versions of the study.*
