Trial summary

From observational studies, it is know that the risk of developing colorectal cancer after polyp removal is lower if the patients adheres to surveillance recommendations. However, colonoscopy is burdensome for patients and colonoscopy availability is limited in many parts of the world. Read more about this study

About this study

Official title: FIT Versus Colonoscopy for Post-polypectomy Surveillance

From observational studies, it is know that the risk of developing colorectal cancer after polyp removal is lower if the patients adheres to surveillance recommendations. However, colonoscopy is burdensome for patients and colonoscopy availability is limited in many parts of the world. In addition, more than half of surveillance colonoscopies are without any findings. The trial investigates whether surveillance using fecal testing for blod is as good as colonoscopy after removal of colorectal polyps.

Read the detailed description

Colorectal cancer is the third most common cancer in the world and develops from benign colorectal polyps. Colonoscopy with polyp removal reduces colorectal cancer incidence and mortality. Patients who have had polyps removed are at increased risk for metachronous polyps and subsequent cancer and are referred to colonoscopic surveillance at regular intervals, the first one usually scheduled three years after polypectomy. Today, these comprise 15-25% of all colonoscopies, but in >85%, no high-risk pathology is found. Thus, post-polypectomy surveillance consumes major resources without benefit to the patients, and these resources are much needed for colonoscopies due to other indications in an aging population. Additionally, colonoscopy requires burdensome bowel-cleansing, discomfort during the examination, absenteeism from work and sometimes need for an escort. Severe complications like bleeding and perforation may occur. Overdiagnosis and overtreatment of benign lesions occur in a large proportion of examinations as most polyps will never develop into colorectal cancer, even if left untreated.

Sensitive fecal occult blood tests (FIT) have been developed that may detect colorectal cancer with the same sensitivity as colonoscopy. The test is cheap, is easily distributed by mail and may be performed at home. If the test detects blood, colonoscopy is indicated. FIT has been used in colorectal screening program for years, but has not yet been thoroughly investigated for post-polypectomy surveillance purposes.

The trial is a pragmatic non-inferiority randomized trial in which patients who are eligible for 3-year colonoscopic surveillance are offered either colonoscopy (standard care) or FIT followed by a colonoscopy in case of a positive test result (Figure 1). FIT may decrease colonoscopy surveillance demand by > 50%, which equals a cost saving of almost 30,000,000 Norwegian kroner annually. By proposing FIT for post-polypectomy surveillance, the trial introduce decentralized and personalized medical follow-up of these patients, and at the same time reduce work-absenteeism, patient discomfort, risk of complications and importantly: overdiagnosis and overtreatment of benign colorectal lesions.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Colorectal cancer incidence

    Measured: 12 years from randomization

Secondary outcomes (9)
  1. Colorctal cancer mortality

    Measured: 12 years from randomization

  2. Advanced neoplasia incidence

    Findings of colorectal cancer and high-risk polyps

    Measured: 3 years from randomization

  3. Findings at colonoscopy

    Pathology detected during colonoscopy in both arms

    Measured: 12 years from randomization

  4. Colonoscopy utilization

    Number of colonoscopies performed

    Measured: 12 years after randomization

  5. Adherence

    Adherence with colonoscopy and FIT surveillance recommendations. Proportion of participants in each arm who are invited for colonoscopy or FIT surveillance and who actually adheres submit the FIT/undergo colonoscopy.

    Measured: 12 years from randomization

  6. Cost-effectiveness

    Total cost for FIT-surveillance and colonoscopy surveillance will be calculated and compared, including reimbursement (FIT, colonoscopy, pathology assessment), payment from patients, travel, absenteism from work, cost of complications etc.

    Measured: 12 years from randomization

  7. Adverse events

    Adverse events after colonoscopy

    Measured: 30 days after colonoscopy

  8. Carbon footprint

    The carbon footprint in each arm will be calculated and compared. Carbon footprint is the total carbon emission from manufacturing, shipping, use, prosessing, litter-handling etc

    Measured: 12 years after randomization

  9. FIT accuracy

    Sensitivity, specificity, postive predictive value and negative predicitive value for colorectal cancer and advanced neoplasia at different FIT-thresholds

    Measured: 3 years after randomization

Questions about this trial

What is this clinical trial studying?

A study testing Fecal occult blood testing and Colonoscopy in people with Colorectal Neoplasms, run by Sorlandet Hospital HF at 1 site in Norway.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 15 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Norway. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Øyvind Holme (004738073000, oyvind.holme@sshf.no), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Colorectal cancer incidence (time frame: 12 years from randomization). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Jan 2026.
