AI model estimates cancer patients' survival from a single face photo
The voices on this episode are generated, and so is the script, from the day's post at Physician in the Loop. Every fact in the post links to its source.
Mass General Brigham researchers reported Oct. 19 that an AI model trained on more than 40 million face photographs predicted survival in cancer patients, sorting them into risk groups whose mortality differed more than threefold.
The study, published in The Lancet Digital Health, tested the model in two independent cancer cohorts, and the authors said a face photo could help with risk stratification when other biomarkers are unavailable. No prospective clinical use has been reported. Separately, the Food and Drug Administration finalized guidance on how drugmakers label apps sold for use with prescription drugs, Radical Numerics said phages designed by its AI model were given to a patient with a drug-resistant infection, and Intuitive reported that da Vinci procedures grew about 14% in the third quarter.
