Artificial intelligence is now being used to improve colorectal cancer screening.
- In France, colorectal cancer is the 3rd most common cancer in men and the 2nd most common cancer in women.
- “Artificial intelligence now makes it possible to signal the presence of polyps and thus detect cancerous lesions that the gastroenterologist would not have seen otherwise,” indicates the Paoli-Calmette Institute.
- “A new development is that artificial intelligence makes it possible to characterize polyps by differentiating inflammatory polyps (whose risk of degeneration is zero) from adenomatous polyps (whose risk of degeneration is around 30%),” also underlines the research Center.
“Artificial intelligence now makes it possible to signal the presence of polyps and thus detect cancerous lesions that the gastroenterologist would not have seen otherwise.”
As Colorectal Cancer Awareness Month comes to an end, the Paoli-Calmettes Institute (IPC) provides an update on the latest advances in screening in a press release.
Colorectal cancer: AI differentiates inflammatory polyps from adenomatous ones
“A new development is that artificial intelligence makes it possible to characterize polyps by differentiating inflammatory polyps (whose risk of degeneration is zero) from adenomatous polyps (whose risk of degeneration is around 30%)”, indicates the research center.
The equipment used (the “GenuisTM Medtronic”) is a system, which, coupled with an endoscope, allows the video stream to be analyzed and then to recognize the type of polyp in real time, based on its shape, color and vascularization.
This device projects an active window in real time during colonoscopy procedures to identify abnormalities related to colorectal polyps. Any anomaly is indicated by the display of a green box, and the sensitivity of the system is around 100%.
Colorectal cancer: “AI remains under the control of the endoscopist”
“This artificial intelligence nevertheless remains under the control of the endoscopist who decides or not, depending on the lesion detected, to resect the polyp. explains Dr Marc Giovannini, head of the digestive endoscopy unit at the IPC.
“Artificial intelligence has nevertheless significantly improved the screening of polyps since we know to date that the rate of adenomas detected using artificial intelligence increases by 50%. And above all, we know that 1% of polyps screened In addition, the risk of cancer occurring between two colonoscopies is reduced by 3%.adds the specialist.
Colorectal cancer: each year, there are 45,000 new cases
Public health problem, colorectal cancer is in France on the 3rdth most common cancer in men and the 2ndth cancer in women after breast cancer. Every year, there are 45,000 new cases in our country.
Organized mass screening, which concerns asymptomatic people aged 50 to 74, aims to diagnose cancer at an early or even pre-cancerous stage. “This type of cancer develops on precancerous lesions, polyps, which can be detected and removed during a colonoscopy,” finishes the Paoli-Calmette Institute. “Colonoscopy is indicated in the event of a positive immunological test”, he concludes.
