Vitamin D, Genes and Colorectal Cancer
Associations Between Genetically Determined Low Vitamin D Level, Vitamin D Intake and Risk of Colorectal Cancer in a Prospective Case-cohort Study in Danes
Aperçu de l'étude
Description détaillée
The association between vitamin D and incidence of colorectal cancer (CRC) has been thoroughly investigated in both observational and experimental studies, but the results are conflicting. Genetic epidemiology is an advantageous alternative to randomized, clinical trials for ethical and economic reasons.
The aim of this study is to investigate whether polymorphisms in GC and CYP2R1 that predicts 25-hydroxycholecalciferol (25(OH)D) concentrations after both ultraviolet B radiation and consumption of vitamin D3-fortified bread and milk in Danes are associated with risk of CRC; and further, to examine whether intake of vitamin D through diet and supplementation alter the risk of CRC.
Data are retrieved from the Danish prospective "Diet, Cancer and Health" study encompassing 57,053 persons which were recruited between 1993 to 1997. Between 1994 and 31th December 2009, 1038 CRC cases has been diagnosed. A sub-cohort of 1857 persons has been randomly selected within the full cohort at time of entry into the cohort. The study design is a nested case-cohort study.

Population étudiée
The Diet, Cancer and Health study is an ongoing Danish cohort study designed to investigate the relation between diet, lifestyle and cancer risk. The cohort consists of 57,053 persons, recruited between December 1993 and May 1997. All the subjects were born in Denmark, and the individuals were 50 to 64 years of age and had no previous cancers at study entry. Blood samples, anthropometric measures and questionnaire data on diet and lifestyle were collected at study entry.
The present study uses a nested case-cohort design. Follow-up is based on population-based cancer registries. Between 1994 and 31th December 2009, 1038 CRC cases were diagnosed. A sub-cohort of 1857 persons has randomly been selected within the full cohort at time of entry into the cohort.
