AI Tool Shows Promise For Treating Brain Cancer, Study Finds

An artificial-intelligence tool has shown promise at helping doctors fight aggressive brain tumors by identifying characteristics that help guide surgery. From a report: The tool -- called the Cryosection Histopathology Assessment and Review Machine, or CHARM -- studies images to quickly pick out the genetic profile of a kind of tumor called glioma, a process that currently takes days or weeks, said Kun-Hsing Yu, senior author of a report released Friday in the journal Med. Surgeons use detailed diagnoses to guide them while they operate, Yu said, and the ability to get them rapidly could improve patients' outcomes and spare them from multiple surgeries. While glioma varies in severity, an aggressive form called glioblastoma can lead to death in less than six months if untreated. Only 17% of people with glioblastoma survive their second year after being diagnosed, according to the American Association of Neurological Surgeons. Surgeons use information about the genetic profile of a glioma tumor when deciding how much tissue to remove from a patient's brain, as well as whether to implant wafers coated in a cancer-fighting drug. Getting that information, however, currently requires time-consuming testing. Yu and his team of researchers trained a machine-learning algorithm to do the work by showing it pictures of samples gathered during brain surgery, and then checking its work against those patients' diagnoses. CHARM learned to match or outperform other AI systems at identifying the genetic profile of a tumor.
