Summary
This is an observational study in a clinical setting to estimate the prevalence of advanced colorectal neoplasia (ACN) at colonoscopy in those with a history of low or high risk polyps or a family history of CRC/polyps and to verify the test performance characteristics of FIT in these populations. Using this information, a risk prediction model will be developed to help guide the choice between FIT and colonoscopy in the ongoing surveillance or screening of patients.
Description
Colonoscopy is an effective tool in reducing colorectal cancer (CRC) incidence, however, it is a limited resource that is not without risk. The overall goal of this study is to determine if Fecal Immunochemical Tests (FIT) could be an effective alternative to colonoscopy for the surveillance of patients at increased risk for CRC. The rationale for this project is that colonoscopy is both a more expensive (30-40X) and more limited resource than FIT, which because of its pivotal role in the investigation and management of many gastrointestinal conditions is constantly in demand.
Routine post-polypectomy surveillance is placing a rapidly growing demand on existing colonoscopy resources, driven in part by the rapid expansion of CRC screening programs.(1) Currently, there are not strong contemporary data to guide the use of colonoscopy or alternative tests for the surveillance of patients after the removal of low or high risk polyps, but colonoscopy is routinely recommended by screening guidelines, as historically no other reasonable options existed. Colonoscopy screening is also the default recommendation for individuals with a family history of CRC or polyps.
It is proposed that the highly sensitive and low cost FIT could replace colonoscopy for post-polypectomy surveillance and primary screening in at least some patients and, thereby, reduce costs while improving access to colonoscopy for other patients.
The following knowledge gaps must be filled prior to advocating the use of FIT for post-polypectomy surveillance or primary screening:
- Contemporary data is lacking on the prevalence of advanced and non-advanced colorectal neoplasia at colonoscopy in a cohort of individuals with well characterized index pathology and/or family history of CRC/polyps.
- There is limited data on the sensitivity and specificity of FIT for the detection of advanced colorectal neoplasia in these settings.
- The factors that predict a higher risk of advanced colorectal neoplasia in those undergoing for post-polypectomy surveillance or a family history are unknown.
This is an observational study conducted in a clinical setting to estimate the prevalence of advanced colorectal neoplasia (ACN) at colonoscopy in those with a history of low or high risk polyps or a family history of CRC/polyps and to verify the test performance characteristics of FIT in these populations. Using this information, a risk prediction model will be developed to help guide the choice between FIT and colonoscopy in the ongoing surveillance or screening of patients.
