Summary

This study looks at whether measuring two proteins (VEGF and MMP) in blood and urine can help predict if a glioblastoma brain tumor will come back within a year after radiation therapy. About 200 adults with this type of brain tumor will provide samples before, during, and after treatment, plus up to 3 years of follow-up. The goal is to develop a simple test that could guide future treatment decisions.
