Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The aim of the study is to investigate the association with functional TLR polymorphisms in relation to risk of CRC and their interaction with dietary factors. Additionally, interactions with previously studied polymorphisms in IL10, IL1B, PTGS2 and NFKB1 will be assessed in order to examine possible biological pathways in meat-induced 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.

Colorectal cancer cases
1038 participants diagnosed with colorectal cancer from the Diet, Cancer and Health cohort.
Observational
Information on diet, lifestyle, weight, height, medical treatment, environmental exposures, and other socio-economic factors were collected at enrolment using questionnaires and interviews
Sub-cohort members
1857 persons randomly selected within the full cohort at time of entry into the Diet, Cancer and Health cohort. These participants serve as controls for the colorectal cancer cases.
