NCT05396560

Brief 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.

Outcome Measures

Primary Outcomes (2)

  • Advanced Colorectal Neoplasia (ACN) Prevalence

    ACN: Colorectal cancer or an advanced adenoma (\> 1 cm, villous features, high grade dysplasia) or serrated polyp (\> 1 cm or any conventional dysplasia).

    At time of colonoscopy

  • Fecal Immunochemical Test Sensitivity and Specificity

    Single fecal sample for measurement of hemoglobin using the OC-Sensor FIT. Positive if measured hemoglobin is ≥100 ng/ml (manufacturers recommended cut off). Sensitivity = proportion of individuals with at least one ACN who had a positive FIT. Specificity = proportion of individuals without advanced lesions who had a negative FIT.

    FIT test to be completed between 3-42 days prior to participant colonoscopy

Eligibility Criteria

Age18 Years - 74 Years
Sexall
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

Participants will include eligible individuals referred to CCSC due to a personal history of low or high risk polyps and/or a family history of CRC/polyps who are medically fit and eligible to undergo colonoscopy at the Centre

You may qualify if:

  • Men or women age ≤ 74 years of age.
  • At least one risk factor for CRC that would generally lead to colonoscopy screening:
  • Personal history of low risk polyps
  • Personal history of high risk polyps
  • Family history of CRC or polyps

You may not qualify if:

  • Known acromegaly, cystic fibrosis or high risk profession (firefighter)
  • Referred for colonoscopy due to a positive fecal immunochemical test or CT colonography
  • Known or suspected gene carrier for a familial cancer syndrome.
  • Does not meet medical criteria for colonoscopy at the CCSC.
  • Colonoscopy within the previous 30 months
  • Unable to provide written informed consent or complete questionnaires due to language barrier or other reasons.
