AI gives high risk scores to nearly 40% of breast cancers at screening

Nearly four in 10 cases of screen-detected and interval cancers had the highest AI risk score at prior screening, suggest findings published October 17 in Radiology.Researchers led by Marthe Larsen from the Cancer Registry of Norway in Oslo also found that nearly one in four screen-detected cancers with AI scores available for two screening rounds had the highest score before diagnosis. “This indicates a potential of AI to detect breast cancer earlier, which could lead to less harmful treatment for the affected female patients,” the Larsen team wrote.AI continues to show its potential in mammographic screening as a standalone method for triaging exams and an assistant to interpreting radiologists. While some previous studies have reviewed AI risk scores on interval cancers, the researchers pointed out that few studies have evaluated these risk scores on prior mammograms of screen-detected cancers. Larsen and colleagues assessed imaging data from BreastScreen Norway and AI scores on mammograms from screening exams prior to breast cancer diagnosis. They included data from 2,787 prior screening mammograms from 1,602 women with an average age of 59 years. The team used a commercially available AI system (Transpara version 1.7.0, ScreenPoint Medical) for the study. The scores issued by the system included the following: 1 to 7, low risk of malignancy; 8 to 9, intermediate risk; and 10, high risk of malignancy. The researchers found that 389 of the screen-detected breast ca...
