DeploymentAn employer has put it into production. Can move the baseline — weighted by scale and how similar the setting is.

Detecting and grading cancer
Finding cancer in biopsies and assigning its grade, such as the Gleason grade for prostate cancer.

Where this applies
One pathology laboratory in Israel. The algorithm was implemented within routine clinical workflow as a second read system to review all prostate core needle biopsies; in routine practice it assessed 11,429 slides from 941 cases, raising 90 high-grade and 560 cancer alerts, of which 51 (9%) led to additional cuts or stains. The study was funded by the developer, some authors report fees from it, and it reports one missed cancer caught by the algorithm.
What this means
AI second reads have been running on every prostate biopsy in at least one laboratory since 2020.
What it does not yet show
One developer-funded laboratory; alerts are not the same as changed diagnoses.
What you can check
Open the Lancet Digital Health article on the prostate biopsy AI deployment and find "second read system to review all prostate CNBs".
Does it change the assessment?
No. The impact index is never moved by a single event. Nor did this record change a layer: all 1 linked judgement above already rested on earlier evidence. This one adds to them.
