About this study

Official title: Predictors of Unsuccessful Endoscopic Mucosal Resection of Complex Colon Polyps: "You Can Look But You Can't Touch"

A prospective outcomes study in patients referred for endoscopic mucosal resection of complex colon polyps.

Read the detailed description

Colon cancer is the third leading cause of cancer-related death in the United States. The number of these deaths has significantly decreased due to screening colonoscopies. A colonoscopy is a procedure in which a physician examines the rectum and large intestines for abnormalities through the use of a specialized camera called an endoscope. Colonoscopies decrease the mortality associated with colon cancer through two main ways: by detecting and removing pre-cancerous lesions called polyps; and by detecting colon cancer at earlier stage, when therapies can still be effective at treating or removing the cancer.

Most colon polyps are small and can be completely removed during a standard colonoscopy. However, there is a growing awareness amongst endoscopists of polyps that are too large or inaccessible to be safely removed during a routine colonoscopy. Previously, these lesions required surgery for removal of the affected part of the colon. There is a growing body of evidence that suggests these more complex colon polyps can be entirely removed endoscopically through a procedure called endoscopic mucosal resection (EMR), thereby avoiding costly and debilitating surgery. Given that it is a novel procedure, it is only available at specialized care centers.

EMR is a procedure identical to a colonoscopy, with more steps involved in the lifting and removal of complex polyps. As many as 80-90% of complex polyps can be successfully removed with EMR. However, it has been noted that removal of the polyp in pieces, rather than as a whole can result in a 20-30% recurrence rate at the resection site. Any manipulation of the polyp prior to EMR may impair the ability to fully remove the lesion. Some factors that have previously been suggested to increase the difficulty of EMR include previous dye injections, removal attempts, and polyp sampling. However, the true impact of previous manipulations of CCPs remains unclear.

This study aims to be one of the largest prospective, multi-centered studies investigating factors that predict the failure of EMR in the removal of complex colon polyps.

What is being measured

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

  1. Endoscopic and clinical factors which predict failure of resection of large colon polyps

    A systematic, prospective collection of data from a large cohorts of patients referred for colon EMR will provide useful data in effort to improve overall patient outcomes.

    Measured: 5 year follow up

Secondary outcomes (2)
  1. Efficacy (%) of Endoscopic resection for large colon polyps

    Measured: 5 year follow up

  2. Factors which predict recurrence of adenoma after large polyp resection

    Measured: 5 year follow up

Questions about this trial

What is this clinical trial studying?

An observational study of Colon Polyps, run by Northwestern University at 4 sites in United States.

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 1 inclusion and 1 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 16 Jun 2017. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 4 sites in United States. 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?

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?

Endoscopic and clinical factors which predict failure of resection of large colon polyps (time frame: 5 year follow up). 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 16 Jun 2017.
