Artificial intelligence (AI) does not automatically improve the detection of precancerous lesions during colonoscopy in people with Lynch syndrome, the most common hereditary condition that raises colorectal cancer risk, according to a new study. Researchers from the University Hospital Bonn (UKB), the University of Bonn, the University of Leipzig, and Amsterdam UMC found that in specialized centers, AI provided no significant additional benefit over standard colonoscopy. The findings were published in The Lancet Gastroenterology & Hepatology.

Key takeaways

  • Lynch syndrome is the most common hereditary predisposition to colorectal cancer, requiring regular colonoscopies.
  • Researchers investigated whether AI improves detection of precancerous lesions in this high-risk group.
  • At specialized centers, AI did not significantly boost detection rates compared to standard colonoscopy.
  • The study was published in The Lancet Gastroenterology & Hepatology.

Background on Lynch syndrome and screening

People with Lynch syndrome have a markedly increased risk of developing colorectal cancer, often at a younger age than the general population. Because of this elevated risk, they undergo regular colonoscopies, typically every one to two years, to detect and remove precancerous polyps before they become malignant. These screenings are crucial for preventing cancer in this vulnerable group.

Study design and findings

The research team set out to determine whether AI-assisted colonoscopy could improve the detection of adenomas, the precancerous lesions that can lead to colorectal cancer. They conducted a study involving patients with Lynch syndrome who underwent colonoscopy at specialized centers. The centers were already known for high-quality examinations and experienced endoscopists.

The results showed that AI did not significantly increase the number of adenomas detected compared to standard colonoscopy. The researchers concluded that in these specialized settings, the expertise of the clinicians already achieved high detection rates, leaving little room for AI to provide additional benefit.

Implications for clinical practice

These findings suggest that AI may not be a universal solution for improving colorectal cancer screening in all populations. For patients with Lynch syndrome who are already receiving care at specialized centers with experienced endoscopists, AI may not offer a meaningful advantage. However, the researchers noted that AI might still be useful in other settings or for less experienced practitioners, though this was not tested in the study.

Frequently Asked Questions

What is Lynch syndrome?

Lynch syndrome is a hereditary condition caused by mutations in genes that repair DNA. It significantly increases a person’s risk of developing colorectal cancer, as well as other cancers such as endometrial, ovarian, and stomach cancer. People with Lynch syndrome are advised to undergo regular cancer screenings, including colonoscopy, starting at a younger age.

How does AI assist in colonoscopy?

AI systems for colonoscopy use computer algorithms to analyze real-time video from the colonoscope. They highlight suspicious areas, such as polyps, that might be missed by the human eye. This technology is designed to help endoscopists detect more precancerous lesions during the procedure.

Why did AI not help in this study?

The study was conducted at specialized centers where endoscopists already had high adenoma detection rates. The researchers believe that the expertise of the clinicians in these settings left little room for AI to improve detection. AI might still be beneficial in less specialized centers or for less experienced practitioners, but this was not evaluated in the study.
