Scientists have designed an AI tool that can rapidly decode a brain tumor’s DNA to determine its molecular identity during surgery--critical information that under the current approach can take a few days and up to a few weeks. Knowing a tumor’s molecular type enables neurosurgeons to make decisions such as how much brain tissue to remove and whether to place tumor-killing drugs directly into the brain--while the patient is still on the operating table. A report on the work, led by Harvard Medical School (HMS) researchers, was published July 7, 2023 in the journal Med. The article is titled “Machine Learning for Cryosection Pathology Predicts the 2021 WHO Classification of Glioma.”
