About this study

Official title: Colorectal Polyp Histology Prediction by Artificial Ingelligence Method Based on NBI Colonoscopy Images.

We have been developing artificial intelligence based polyp histology prediction (AIPHP) method to classify Narrow Band Imaging(NBI) colonoscopy images to predict the hyperplastic or neoplastic histology of polyps.

We plan to study colonoscopy polyp samples taken by polypectomy from 1200 patients.The documented NBI still images will be analyzed by the AIPHP method and by the NICE classification parallel.Our aim is to analyze the accuracy of AIPHP and NBI classification based histology predictions and also compare the results of the two methods.

Read the detailed description

Background:

Colonoscopy with polypectomy or early colorectal neoplastic lesions (polyp) is a proven and widely accepted method of reducing colorectal cancer mortality rates.

Predicting histology prior to endoscopic colorectal polyp removal is useful especially for diminutive (1-5mm) and small (6-10mm ) polyps.

Evaluation of colorectal polyps using the narrow-band imaging (NBI) technique and the NBI International Colorectal Endoscopic (NICE) classification are useful to predict the histology during endoscopy.However, NBI and magnification based polyp histology prediction needs training and endoscopic experience. Morever , the final and objective diagnosis still requires histology.

Therefore,we have been developing arteficial intelligence-based polyp histology prediction (AIPHP) software to automatically evaluate the magnified NBI colonoscopy images aiming the histology prediction of polyps.

Materials and methods:

We plan to examine 1200 colorectal polyps obtained from patients. Polyps will be removed by traditional polypectomy or with mucosectomy.Endoscopic procedures and histological examinations performed at the participation hospitals. Colonoscopy will be performed with Olympus EXERA III CFHQ190I (Olympus ,Tokyo,Japan) high reolution NBI colonoscopes providing 65x optical magnification. Colorectal polyps will be detected first by high definition colonoscopy then by NBI at the optical maximum magnification (65x). All studied polyps will be photo-documented. The stored NBI photos were anelyzed by the NICE classification and AIPHP parallel system.

Histological examination methods:

We use WHO classification of colorectal polyps. The two -class classification will considere hyperplastic or neoplastic ((SSLs,tubular or villous adenomas, and invasive adenocarcinomas).

AIPHP software systtem:

The AIPHP software is based on the categorization of the vascular pattern and color of the polyps.The main steps of AIPHP software development will be the following: 1) feature vector calculation 2) training of classifier module, and 3) AIPHP classifier testing. Five features will be used by our AIPHP software.

Questions about this trial

What is this clinical trial studying?

An observational study of Colorectal Polyp, run by Petz Aladar County Teaching Hospital.

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: status not confirmed, as of the sponsor's last update on 22 Sep 2022. 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?

Results are not available in the source record.

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?

Polyp histology accuracy by AI method (time frame: two weeks). 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 22 Sep 2022.
