Trial summary

Colorectal cancer (CRC) is the second most common cancer and the fourth leading cause of cancer death in Korea. Colonoscopy with polypectomy decreases the incidence and mortality from colorectal cancer. However, significant lesions can be missed during colonoscopy. Read more about this study

About this study

Official title: Can Involvement of Endoscopy Nurse Participation Increase Adenoma Detection Rate During Screening Colonoscopy?:A Prospective Multicenter Randomized Trial

Colorectal cancer (CRC) is the second most common cancer and the fourth leading cause of cancer death in Korea. Colonoscopy with polypectomy decreases the incidence and mortality from colorectal cancer. However, significant lesions can be missed during colonoscopy. Recent retrospective studies have shown that fellow involvement as a second observer may increase adenoma detection rate in colonoscopy.

The aim of this prospective, multicenter, randomized study is to evaluate the impact when endoscopy nurse participate in adenoma detection during screening colonoscopy. The primary outcome measure is the adenoma detection rate (ADR).

Being tested

Questions about this trial

What is this clinical trial studying?

A Phase 4 study of Polyp and Adenomatous Polyp, run by Soon Chun Hyang University at 6 sites in South Korea.

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 2 inclusion and 6 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: finished, as of the sponsor's last update on 17 Feb 2011. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 sites in South Korea. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

adenoma detection rate (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01124266, which also lists 3 linked publications.

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 17 Feb 2011.
