BMC Cancer, 14(1), 992.
- Glioblastoma multiforme (GBM) is the main primary malignant brain tumor in adults. Almost all GBM show a recurrence with the highest risk in the tumor bed.
- Following the standard treatment protocol for primary GBM, the local progression-free survival time is 7 months in median with a typical overall survival of around 15 months.
- INTRAGO is the first phase I/II dose-escalation study for newly diagnosed GBM investigating the addition of intraoperative radiation therapy (IORT) to the standard radio-chemotherapy treatment for newly diagnosed GBM using the INTRABEAM® device of Carl Zeiss Meditec AG.
