Adenoma
MONDO:0004972A neoplasm arising from the epithelium. It may be encapsulated or non-encapsulated but non-invasive. The neoplastic epithelial cells may or may not display cellular atypia or dysplasia. In the gastrointestinal tract, when dysplasia becomes severe it is sometimes called carcinoma in situ. Representative examples are pituitary gland adenoma, follicular adenoma of the thyroid gland, and adenomas (or adenomatous polyps) of the gastrointestinal tract.
Also known as: adenoma, acinar cell adenoma, acinar cell adenoma (morphologic abnormality), adenoma, benign

AI and cap team up to spot hidden colon polyps
Disease control CompletedThis study tested whether using an artificial intelligence system (GI GENIUS) together with a special cap (ENDOCUFF VISION) on the colonoscope helps doctors find more precancerous polyps during colonoscopy than using either tool alone. About 481 adults undergoing screening or fol…

AI boosts polyp detection in colon cancer screening Follow-Up
Diagnosis CompletedThis study tested whether an AI tool (GI Genius) helps doctors find more polyps during colonoscopy in people aged 50-74 who had a previous polyp. Over 1,100 participants were randomly assigned to either AI-assisted or standard colonoscopy. The main goal was to see if AI increases…

Blood test may spot colon cancer early, study shows
Diagnosis CompletedThis study tested a new blood test designed to find colorectal cancer early in people at average risk. Nearly 49,000 adults aged 45-85 gave a blood sample before their routine colonoscopy. The goal was to see how well the blood test could detect cancer and advanced growths compar…

Camera pill could revolutionize bowel cancer screening
Diagnosis CompletedThis study tested whether using a camera capsule (a pill you swallow) as a first test for bowel cancer screening could encourage more people to get screened and find more polyps or cancers. Over 2,000 people in Denmark took part. The goal was to see if this approach reduces the n…

Glow-in-the-Dark tool may make parathyroid surgery safer and faster
Symptom relief CompletedThis study tested a device called PTeye that uses near-infrared light to help surgeons spot parathyroid glands during surgery for hyperparathyroidism. The goal was to see if it could reduce the number of tissue samples sent to the lab and lower the risk of needing a second surger…
