In the treatment of glioblastoma (GBM) neurosurgical resection of the tumor is usually considered a a first step of effective therapy. Radical resection of the tumor is highly beneficial to the patient as measured in progression-free survival and overall survival. At the same time eloquent areas of the brain have to remain intact to preserve quality of life.
Both 5-ALA fluorescence and intraoperative MRI are used for intraoperative marking of tumor tissue and thereby to improve precision of GBM-Resection.
We now study whether the combination of 5-ALA fluorescence and intraoperative MRI increases the number of sites where tumor tissue can be detected.
