The All Adenomas study

ABSTRACT: Background and study aims
Bowel polyps are small, benign (harmless) growths found on the inner lining of the colon (end part of the large intestine) or rectum. They are not usually cancerous, however if they are found they should be removed as some will eventually turn into cancer if left untreated. People who have been found to have bowel polyps need to undergo surveillance to monitor their growth. Current UK guidelines for the surveillance of people found to have bowel polyps classify people into those who are at low, intermediate or high risk of developing bowel cancer in the future. This guideline was developed in 2002 and now needs to be re-examined. People with intermediate risk bowel polyps are currently recommended to have 3-yearly surveillance colonoscopy (test to look inside the intestine with a camera on a flexible tube). This is likely a good option for some people in the intermediate risk group, but it may not be the best option for others. The aim of this study is to evaluate the effectiveness of the current surveillance guidelines.
This study is being extended to assess surveillance in low-risk and high-risk bowel polyp groups. Under the current guidelines, people with low-risk bowel polyps are recommended either no surveillance or colonoscopy at 5 years. In contrast, people with high-risk polyps are recommended to have a colonoscopy at least every three years and maybe more frequently to begin with. The aim of this study is to assess the effectiveness of these guidelines; to understand whether it is safe for people within the low-risk group not to have a colonoscopy, and whether there are people within the high-risk group who do not require such intensive surveillance. The study also re-examines surveillance in the intermediate-risk group with longer follow-up.
Who can participate?
Men and women of any age who have bowel polyps who have had a colonoscopy
What does the study involve?
The study uses material from several high-quality databases in hospitals or from bowel cancer screening initiatives to identify groups of patients with bowel polyps. Information from routine colonoscopies conducted to the current surveillance programme is collected and used to see if patient’s polyps worsen or turn into cancer at later visits.
DISEASE(S): Intermediate-risk Adenoma(s) (three Or Four Small Adenomas,Including Those With Low-risk Adenoma(s) (one Or Two Small Adenomas),Or One Or Two Large Adenomas) Or High-risk Adenoma(s) (five Or More Small Adenomas,Or Three Or More Large Adenomas),Patients Diagnosed With Adenomas At Colonoscopy
