While many people know to get their colon screened when they turn forty-five, most aren't aware that the rates at which polyps are missed varies among gastroenterologists from six to forty-one percent. That's not good since precancerous polyps are what lead to colon cancer, the third deadliest cancer in the US. But a new study shows when artificial intelligence is used in colonoscopies, it cuts the number of polyps missed by a whopping thirty percent. That's significant when you consider that a screening without AI already cuts a person's risk of dying from colon cancer by sixty percent.
The study involved two hundred patients and compared the standard white light colonoscopy with one using deep-learning based computer-aided detection system. One group got the standard colonoscopy first immediately followed by the computer aided colonoscopy while the other group had the testing order reversed. The same doctor performed both. Patients who underwent the computer aided colonoscopy first had a miss rate of about twenty percent while those who first underwent standard white light colonoscopy had a miss rate of thirty four percent.
AI was profoundly better at missing fewer polyps and it's expected to be even better as the machine learning improves. Deep learning artificial intelligence is just beginning to be applied to diagnostic testing in medicine but its role and importance can't be overstated.

Deep Learning Computer-aided Polyp Detection Reduces Adenoma Miss Rate: A United States Multi-center Randomized Tandem Colonoscopy Study (CADeT-CS Trial)
Artificial intelligence-based computer-aided polyp detection (CADe) systems are intended to address the issue of missed polyps during colonoscopy. The effect of CADe during screening and surveillance colonoscopy has not previously been studied in a United States (U.S.) population...
What Is Colorectal Cancer Screening?
olorectal cancer almost always develops from precancerous polyps (abnormal growths) in the colon or rectum. Screening tests can find precancerous polyps, so that they can be removed before they turn into cancer...
Medicine...
Medicine is constantly advancing – that is a great thing about life in the 21st century. But it doesn’t just happen. Dedicated biomedical scientists are making discoveries that translate into those new medical advances.
Biomedical science is broad, encompassing everything from social science to microbiology, biochemistry, epidemiology, to structural biology and bioinformatics to name just a few areas. And, it can involve basic fundamental biology, the use of AI and chemistry to clinical studies that evaluate new medicines in patients.
No matter the research focus, the goal is always the same, to advance human health. It may take a few months, a few years or for fundamental science, a few decades. Few people make the connection that biomedical science is medicine and that biomedical scientists are working today on the medicine of tomorrow. Our weekly 500-word newspaper columns and 2-minute radio shows and podcasts provide insights into a broad range of biomedical science topics.
Medical Discovery News is dedicated to explaining discoveries in biomedical research and their promise for the future of medicine.
