IBD Neoplasia Surveillance RCT
April 2, 2024 updated by: Ottawa Hospital Research Institute
A Randomized Controlled Non-Inferiority Trial Comparing Neoplasia Detection During Colonoscopy Screening With and Without Non-Targeted Biopsies in Adult Colonic Inflammatory Bowel Disease
We will conduct a multicenter, parallel-group, non-inferiority RCT in persons with IBD undergoing colorectal neoplasia screening with high-definition white light colonoscopy, comparing a strategy of sampling visible lesions alone to a conventional strategy of sampling both visible lesions as well as normal-appearing mucosa using non-targeted biopsies.
The primary outcome is the neoplasia detection rate.
The required sample size to demonstrate non-inferiority is 1952 persons.

Description
Inclusion Criteria:
Each potential participant must satisfy all of the following criteria to be enrolled in the study.
- ≥ 18 years old
- Historical endoscopic/histologic disease extending beyond the rectum in UC or involving ≥ 1/3 of colorectum in CD> 50% of colon present, with remaining colon meeting above minimum criteria for disease extent (beyond rectum in UC, ≥1/3 colorectum in CD)
- cIBD ≥ 8 years duration (or at any time after diagnosis if a patient also has primary sclerosing cholangitis)
In symptomatic remission at time of colonoscopy
- For CD: Harvey-Bradshaw Index < 541
- For UC or IBDU: Partial Mayo Score ≤ 242
- Major purpose of colonoscopy is neoplasia screening/surveillance
- Undergoing colonoscopy with high-definition white light endoscopy
Exclusion Criteria:
- Persons who are unable to provide informed consent
- Persons with a history of colorectal cancer
- Persons with prior subtotal or total colectomy (>50% of colon removed)
- Persons undergoing repeat colonoscopy to follow-up on recently diagnosed neoplasia identified within the past year
- Persons undergoing pancolonic chromoendoscopy or pancolonic virtual chromoendoscopy
- Colon mucosa visibility deemed inadequate for surveillance after washing/suctioning (Boston Bowel Preparation Score of 0 or 1 in any segment)
- Incomplete colonoscopy (unable to reach cecum or terminal ileum [if no cecum])
- Moderate-to-severe inflammation (Mayo 2-3) involving ≥ 25% of colorectum or mild inflammation (Mayo 1) involving ≥ 50% of colorectum
