  • Research summary

    Individuals suffering from inflammatory bowel disease (IBD), a group of conditions characterised by chronic inflammation of the gastrointestinal tract, are at a significantly increased risk of developing colon cancer. Those patients with associated primary sclerosing cholangitis display a further increased cancer risk. Consequently, IBD patients are offered enrolment into surveillance programs, aiming to detect precursor lesions in their early developmental stages where curative treatment is possible. However, these programs are costly, invasive and of limited efficacy. In consideration of this, we would like to assess whether the molecular characterisation of colitis-affected bowel tissue can improve cancer risk prediction, by comparing the molecular signatures of bowel tissue from individuals who later develop lesions, to those who do not. The aim is to be able to identify and validate molecular markers, robust in archival tissue, that stratify IBD patients according to their risk of developing IBD-associated colon cancer. Furthermore, we would also like to compare IBD-associated colorectal lesions with colorectal lesions that occur in patients without IBD, also known as sporadic adenomas, to determine their evolutionary and molecular differences.
