Trial summary

Current recommendations for colonoscopy screening programs usually involve patients older than 50 years of age. However, little is known about polyp or adenoma detection rates under 50. We compared these detection rates according to age in a large series of patients in common practice. Read more about this study

Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 15 to 99 years
  • All sexes
  • Child, Adult, Older adult

Study population: During the study period, 6335 colorectal endoscopic procedures were realized in the endoscopy unit. We excluded 278 sigmoidoscopies and 30 interventional procedures for stent insertion or stenosis dilation. Only diagnostic colonoscopies were recorded, performed in 3308 women (54.9%) and 2719 men (45.1%) with a median age of 57 (range, 15-96: IQR 18).

Who may be able to join

  • All consecutive patients who were scheduled for colonoscopy were included.

Who cannot join

  • patients scheduled for partial colonoscopy, interventional colonoscopy (for stent insertion, stenosis dilation).

About this study

Official title: Adenoma and Advanced Neoplasia Detection Rates Increase From 45 Year of Age: Results of a Monocentric One-year Observational Cohort Study on 6027 Colonoscopies

Current recommendations for colonoscopy screening programs usually involve patients older than 50 years of age. However, little is known about polyp or adenoma detection rates under 50. We compared these detection rates according to age in a large series of patients in common practice.

Methods: All colonoscopies performed in 2016 in our unit were prospectively recorded. We determined adenoma detection rate (ADR), polyp detection rate (PDR), mean number of polyps (MNP), and advanced neoplasia detection rate (ANDR).

Read the detailed description

Patients All consecutive patients who were scheduled for colonoscopy were included. Exclusion criteria were: patients scheduled for partial colonoscopy, interventional colonoscopy (for stent insertion, stenosis dilation).

Data collection The following data have been prospectively collected: age, gender, indication for colonoscopy, preparation procedure and quality of the preparation (assessed by the Boston Bowel Preparation Scale; BBPS) [19-20], caecal intubation (yes/no), withdrawal time, number and size of polyps and polyp histopathology.

All clinical data were collected during the procedure by a nurse and an endoscopist on a dedicated software. The database was then supplemented by the Clinical Research Associate for histopathological data.

We determined adenoma detection rate (ADR; percentage of colonoscopies with at least one adenoma), polyp detection rate (PDR: percentage of colonoscopies with at least one polyp), mean number of polyps per colonoscopy (MNP), large polyp detection rate (LPDR; percentage of colonoscopies with at least one polyp of 1 cm or more) and advanced neoplasia detection rate (ANDR: percentage of colonoscopies with at least one advanced neoplastic lesion as defined below).

  • ColonoscopyProcedure or surgery

    Total colonoscopy : All consecutive patients who were scheduled for colonoscopy were included. Exclusion criteria were: patients scheduled for partial colonoscopy, interventional colonoscopy (for stent insertion, stenosis dilation).

What is being measured

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

  1. Adenoma detection rate according to age

    ADR <30yo, in 30-34 yo, in 35-39yo, in 40-44yo, in 45-49yo, in 50-54yo, in 55-59yo, in 60-64yo, in 65-69 yo, in 70-74yo, in 75-79yo and >79yo intervals

    Measured: during colonoscopy

  2. Advanced Neoplasia Detection rate according to age

    ANDR <30yo, in 30-34 yo, in 35-39yo, in 40-44yo, in 45-49yo, in 50-54yo, in 55-59yo, in 60-64yo, in 65-69 yo, in 70-74yo, in 75-79yo and >79yo intervals

    Measured: during colonoscopy

Secondary outcomes (6)
  1. Age

    years old

    Measured: during colonoscopy

  2. Gender

    Male or Female

    Measured: during colonoscopy

  3. Indication for colonoscopy

    pain / screening/ familial or personal history of polyp or cancer

    Measured: during colonoscopy

  4. quality of the preparation

    Boston Bowel Preparation Scale Segment Score Description 0: unprepared colon segment with mucosa not senn due to solid stool that cannot be cleared

    1. Portion of mucosa of the colon segment seen, but other areas of the colon segment are not well seen due to staining, residual stool, and/or opaque liquid
    2. minor amount of residual staining, small fragments of stool, and/or opaque liquid, but mucosa of colon segments is seen well
    3. entire mucosa of colon segment seen well, with no residual staining, small fragments of stool or opaque liquid

    Total score is a summation of scores from three segments of the colon Score is from 0 to 9

    Measured: during colonoscopy

  5. Caecal intubation

    Y/N

    Measured: during colonoscopy

  6. Withdrawal time

    in seconds

    Measured: during colonoscopy

Questions about this trial

What is this clinical trial studying?

An observational study of Colonic Polyp and Colon Adenoma, run by Société Française d'Endoscopie Digestive.

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 5 Dec 2017. Status can change between updates, so confirm with the study contact before making plans.

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?

Adenoma detection rate according to age (time frame: during colonoscopy). The study lists 2 primary outcomes in all. 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 5 Dec 2017.
