NCT04067778

Brief Summary

To determine if random biopsies can be safely eliminated from screening of average risk persons with IBD, the investigators propose to carry out a pilot randomized control trial in which targeted biopsies in combination with random biopsies will be compared to targeted biopsies alone in terms of pre-cancerous lesion capture rate, side-effects and CRC risk. The pilot study will aim to capture 20% of the overall study population in order to evaluate the feasibility of recruiting the needed number of participants in the specified time frame, while maintaining high quality of data collection.

Study Arms (2)

Intervention Group

EXPERIMENTAL

Participants will undergo standard colonoscopy as part of their routine IBD surveillance. During this colonoscopy targeted biopsies (biopsies of any pre-cancerous lesions observed by the doctor) and/or removal of any polyps will be undertaken.

Diagnostic Test: Intervention Group

Control Group

OTHER

Participants will undergo standard colonoscopy as part of their routine IBD surveillance. During this colonoscopy both random (approximately 32 to 40) and targeted biopsies (and/or removal of any polyps) will be undertaken.

Diagnostic Test: Control Group

Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • ≥ 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

You may not qualify if:

  • Persons who cannot or are unwilling to provide informed consent
  • Persons with a history of colorectal cancer
  • Persons with prior subtotal or total colectomy (\> 50% of colon removed)
  • Persons undergoing colonoscopy to follow-up on recently diagnosed neoplasia identified within the past year
  • Persons undergoing pancolonic 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)
  • Moderate-to-severe inflammation (Mayo 2-3) involving ≥ 25% of colorectum or mild inflammation (Mayo 1) involving ≥ 50% of colorectum
