About this study

Official title: Computer-aided Real-time Automatic Quality-control System for Detection of Early Cancer and Precancerous Lesions on Upper Gastrointestinal Tract: a Multicenter Randomized Controlled Study

The purpose of our study was to assess the performance of esophagogastroduodenoscopy automatic quality-control system in real-time quality control of EGD.

Read the detailed description

Investigators developed a real-time quality control system of esophagogastroduodenoscopy(EGD) named EGD automatic quality-control system (AQCS). Investigators carried a prospective multicenter randomized controlled trial to assess the performance of this system in quality control of real-time EGD, including detecting the early upper gastrointestinal cancer and precancerous lesions, assessing inspection completeness, mucosal visibility, time of EGD procedure and other indicators.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Computer-aided Real-time Automatic Quality-control SystemDevice

    EGD automatic quality-control system(AQCS),developed based on deep convolutional neural network (DCNN) models,could facilitate real-time detection of upper gastrointestinal lesions, assess inspection completeness and mucosal visibility, and calculate time of EGD procedure.

Study groupRoleWhat they receive
AQCS-aided groupExperimentalPatients in AQCS-aided group will go through white light EGD examination with assistance of AQCS.
Receives: Device: Computer-aided Real-time Automatic Quality-control System
Control groupNo interventionPatients in control group will go through white light EGD examination without AQCS.

What is being measured

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

  1. Detection rate of early cancer and precancerous lesions on upper gastrointestinal tract confirmed by pathological examination

    The primary outcome is the detection rate of early cancer and precancerous lesions on upper gastrointestinal tract confirmed by pathological examination per group.

    Measured: 6 months

Secondary outcomes (4)
  1. Detection rate of early cancer and precancerous lesions on upper gastrointestinal tract in tertiary hospitals and secondary hospitals.

    Effect of detection rate of early cancer and precancerous lesions on upper gastrointestinal tract from tertiary hospitals and secondary hospitals with assistance of AQCS.

    Measured: 6 months

  2. Mean inspection completeness of two groups.

    Inspection completeness includes taking standard images of each parts of esophageal and gastric cavity.

    Measured: 6 months

  3. Mean inspection time of EGD procedure of two groups.

    Inspection time of EGD procedure is the time endoscopy inserting to withdrawing the mouth and does not include the time of biopsy.

    Measured: During procedure

  4. Detection rate of early cancer and precancerous lesions on upper gastrointestinal tract from senior, intermediate and primary endoscopist with assistance of AQCS.

    Effect of detection rate of early cancer and precancerous lesions on upper gastrointestinal tract from senior, intermediate and primary endoscopist with assistance of AQCS.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study of Esophagogastroduodenoscopy, run by Shandong University at 6 sites in China.

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 3 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: finished, as of the sponsor's last update on 29 May 2024. 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 China. 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?

Detection rate of early cancer and precancerous lesions on upper gastrointestinal tract confirmed by pathological examination (time frame: 6 months). 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 NCT04720924, which also lists 1 linked publication.

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 29 May 2024.
