Brain tumors can be deadly, and surgery is often needed to remove them. To ensure that all the cancer cells have been removed, and reduce the risk of cancer recurrence, brain tissue samples are checked under a microscope for signs of cancer during the surgery. The faster this can be done, the safer it is for the patient. So, researchers have developed a new method called true-H&E Rapid Fresh digital-Pathology. This digital pathology is 4x faster than current methods and movable. It also does not require additional training for the pathologist, as H&E staining is already standard, and works on ‘unfixed’ fresh samples, avoiding damage (called artifacts) from freezing. A trial of the method demonstrated that normal versus tumor tissue can still be readily distinguished. Overall, this technology could make brain tumor surgeries faster and more effective for patients, improving their outcomes and even has potential applications in other tissues that could speed up assessment for more cancer types, including breast cancer.
