Impact of Artificial Intelligence (AI) on Adenoma Detection During Colonoscopy in FIT+ Patients. (AIFIT)

Impact of AI (Artificial Intelligence) on Adenoma Detection During Colonoscopy in FIT+ Patients: a Prospective Randomized Controlled Trial
The Italian screening program invites the resident population aged 50-74 for Fecal Immunochemical Test (FIT) every 2 years.
Subjects who test positive are referred for colonoscopy.
Maximizing adenoma detection during colonoscopy is of paramount importance in the framework of an organized screening program, in which colonoscopy represent the key examination.
Initial studies consistently show that Artificial iIntelligence-based systems support the endoscopist in evaluating colonoscopy images potentially increasing the identification of colonic polyps.
However, the studies on AI and polyp detection performed so far are mostly focused on technical issues, are based on still images analysis or recorded video segments and includes patients with different indications for colonoscopy.
At the best of our knowledge, data on the impact on AI system in adenoma detection in a FIT-based screening program are lacking.
The present prospective randomized controlled trial is aimed at evaluating whether the use of an AI system increases the ADR (per patient analysis) and/or the mean number of adenomas per colonoscopy in FIT-positive subjects undergoing screening colonoscopy.
Therefore Patients fulfilling the inclusion criteria are randomized (1:1) in two arms: A) patients receive standard colonoscopy (with high definition-HD endoscopes) with white light (WL) in both insertion and withdrawal phase; all polyps identified are removed and sent for histopathology examination; B) patients receive colonoscopy examinations (with HD endoscopes) equipped with an AI system (in both insertion and withdrawal phase); all polyps identified are removed and sent for histopathology examination.
In the present study histopathology represents the reference standard.

Description
Inclusion Criteria:
- Consecutive adult (50-74 yrs.) outpatients undergoing colonoscopy in the frame of the FIT-based screening program.
Exclusion Criteria:
- patients with CRC history or hereditary polyposis syndromes or hereditary non-polyposis colorectal cancer
- patients with inadequate bowel preparation
- patients in which cecal intubation was not achieved or scheduled for partial examinations
- patients with gastrointestinal symptoms
- polyps could not be resected due to ongoing anticoagulation preventing resection and pathological assessment

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
No Intervention: Standard WL (white light) colonoscopy
all patients receive standard colonoscopy (with high definition- HD- endoscopes) with white light (WL) in both insertion and withdrawal phase; all polyps identified are removed and sent for histopathology examination.

Experimental: Standard colonoscopy with assistance of Artificial Intelligence (CAD-EYE (Fujifilm Co, Tokyo, Japan)
all patients receive colonoscopy examinations (with HD endoscopes) equipped with an Ai system (CAD-EYE, Fujifilm Co, Tokyo, Japan) in both insertion and withdrawal phase).
This system is a real-time computer-assisted image analysis that allows automatic polyp identification without modifications to the colonoscope or to the actual endoscopic procedure.
When CAD EYE identifies a polyp, both a visual (a green blinking box surrounding the identified polyp, called the detection box) and an acoustic alarm pop up and attract the endoscopist attention.
Around the endoscopic image a visual assist circle is shown and lights up in the direction where the suspicious polyp is detected.All polyps identified are removed and sent for histopathology examination.

A dedicated CNN-based AI system (CAD EYE, Fujifilm Co, Tokyo, Japan) has been recently developed.
The Computer-aided diagnosis (CAD) CAD EYE system is a real-time computer-assisted image analysis that allows automatic polyp identification without modifications to the colonoscope or to the actual endoscopic procedure.
When CAD EYE identifies a polyp, both a visual (a green blinking box surrounding the identified polyp, called the detection box) and an acoustic alarm pop up and attract the endoscopist attention.
Around the endoscopic image a visual assist circle is shown and lights up in the direction where the suspicious polyp is detected.
