Summary
This is a cross-sectional study aimed at identifying factors which best predicts patients at high risk of colorectal cancer or colorectal adenomas and to develop a risk prediction model.
Description
Bowel cancer is the second commonest cause of cancer death in the UK with 16000 people dying per year. Although the NHS Bowel Cancer Screening Programme (BCSP) detects cancers at an earlier stage only 10% of all cancers are detected through screening.
Currently, the only criteria for screening is age and no account is taken of other known risk factors such as smoking, alcohol, family history or obesity. Stool FIT (a new stool test which detects blood that can't be seen with the naked eye) will be introduced into the English BCSP, but there is poor evidence for its use in patients presenting with symptoms. There is also emerging data that there may be differences in the gut bacteria of people with and without cancer or pre cancerous bowel polyps (adenomas).
This will be a national multi-centre study over 5-years. 10000 Patients undergoing colonoscopy as part of BCSP or due to symptoms will be recruited. Patients will be asked to fill in a health questionnaire, have their height, weight, waist circumference measured. Patients will also receive blood tests, stool tests or saliva tests depending on the indication for their colonoscopy. The results of the colonoscopy and any samples taken will be collated. Patients will receive a patient experience questionnaire or food frequency questionnaire. A further 10,000 patients from the North of England will be consented to be contacted for future studies with some of the information above collected.
The aim of this study is to develop a risk prediction model to help determine which patients are at highest risk of having adenomas or bowel cancer. The investigators will also explore the significance of the gut bacteria composition in patients with adenomas or cancer to help inform this risk model. Additionally the investigators will develop a large platform of patients who consent to be contacted for future research.
