Artificial intelligence has reduced by two times the number of missing polyps in the first cancer test, according to a team of international researchers led by the Mayo Clinic. The study was published in Gastroenterology.

Mostly polyps of the intestine they are harmless, but some over time develop into cancer of the intestine or rectum, which can be fatal if it is found in the later stages. It is the second deadliest cancer in the world, with an estimated 1.9 million deaths and 916,000 deaths worldwide by 2020, according to the World Health Organization. Colonoscopy is a test used to detect changes or abnormalities in the large intestine (rectum) and rectum.

Between February 2020 and May 2021, 230 study participants each used the last two boxes in one day in eight hospitals and community hospitals in the US, UK and Italy. One colonoscopy uses AI; the other, for example colonoscopy, did not.

The incidence of precancer-colored polyps is estimated at 25%. In this study, the error rate was 15.5% in the group with primary AI colonoscopy. The mean loss was 32.4% in the group that underwent standard colonoscopy. The AI ​​colonoscopy detected additional polyps that were small, soft and in the small intestine at close range.

“Cancer can almost completely be prevented with proper diagnosis,” said lead author Michael B. Wallace, MD, head of the department of gastroenterology and liver at Sheikh Shakhbout Medical City in Abu Dhabi, United Arab Emirates and Fred C Andersen Professor of Medicine at Mayo Clinic in Jacksonville, Fla. “Benefit artificial intelligence to discover intestinal polyps and the possibility of saving lives is welcome and exciting news for patients and their families. “

In addition, false positives were 6.8% in the group with primary AI colonoscopy. It was 29.6% in the weighted group colonoscopy first. The negative-negative results indicate that you do not have a specific environment, when you actually do.
