About this study

Official title: Artificial Intelligence for Onsite Cytology Evaluation in Endoscopic Ultrasound

The aim of this study is to determine if the widely available artificial intelligence platform ChatGPT can accurately identify the abnormalities present on cytology specimens obtained at EUS-FNB of solid mass lesions in the gastrointestinal tract, in comparison with interpretation by cytopathologists as the gold standard.

Read the detailed description

The diagnostic accuracy of EUS-guided fine needle biopsy of lesions in the gastrointestinal tract is dependent on the availability of a cytopathologist to render a rapid on-site evaluation (ROSE), with studies showing that the presence of an on-site cytopathologist improves the diagnostic yield, decreases the number of inadequate or unsatisfactory samples, and limits the number of passes required to establish a diagnosis. However, the availability of ROSE is variable across centers and regions, with the availability of onsite cytopathology services limited to a handful of tertiary referral centers in the United States.

ChatGPT is a universally available, generative artificial intelligence program developed by OpenAI. The aim of this study is to determine if this AI platform can accurately identify the abnormalities present on cytology specimens obtained at EUS-FNB of solid mass lesions in the gastrointestinal tract, in comparison with interpretation by cytopathologists as the gold standard.

Questions about this trial

What is this clinical trial studying?

An observational study of Gastrointestinal Neoplasm and Mass Lesion, run by Orlando Health, Inc. at 1 site 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 2 inclusion and 3 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: under way, not looking for participants, as of the sponsor's last update on 30 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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?

This study is still under way. Results are not available in the source record yet.

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?

Diagnostic adequacy at rapid onsite evaluation (time frame: 1 day). 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 30 Jun 2026.
