Glioblastomas are aggressive brain tumors that are commonly diagnosed through a risky and invasive surgical biopsy. A team of researchers led by Hong Chen at Washington University in St. Louis has developed a noninvasive diagnostic method that may one day replace the tissue biopsy with a simple blood test.
Chen, associate professor of biomedical engineering in the McKelvey School of Engineering and of radiation oncology in the School of Medicine; Eric Leuthardt, MD, professor of neurosurgery at Washington University School of Medicine and of biomedical engineering in McKelvey Engineering; and the team tested the method in both small and large animal models and found significantly improved detection and diagnostic sensitivity for brain tumors via a simple blood sample.
