Marker Found For The Most Malignant Brain Tumors

Researchers at Penn State's College of Medicine have identified a marker for certain types of brain tumors, including glioblastoma multiforme (GBM), which are the most prevalent and difficult-to-manage. The marker, interleukin 13 receptor, is present in over 90% of patients with GBM, making it a valuable diagnostic tool.
