Brief Summary
Boron Neutron Capture Therapy (BNCT) is an experimental radiation therapy technique that is based on the principle of irradiating boron atoms with neutrons. When neutrons have relatively low energy, boron atoms that have been targeted to cancerous tissue using a suitable boron carrier (an amino acid derivative called BPA, boronophenylalanine) will capture the neutrons. As a result from the neutron capture the boron atoms will split into two, producing helium and lithium ions. The helium and lithium ions, in turn, have only a short pathlength in tissue (about 5 micrometers) and will deposit their cell damaging effect mainly within the tumor provided that the boron carrier (BPA) has accumulated in the tumor. In practice, the study participants will receive BPA as an approximately 2-hour intravenous infusion, following which the tumor is irradiated with low energy (epithermal) neutrons obtained from a nuclear reactor at the BNCT facility. BNCT requires careful radiation dose planning, but neutron irradiation will last approximately only for one hour. In this study BNCT is given only once. The study hypothesis is that glioblastoma tissue may accumulate the boron carrier compound, and glioblastoma might respond to BNCT.

Eligibility Criteria
You may qualify if:
- Histologically confirmed glioblastoma multiforme
- Supratentorial location
- At least 30% of the tumor volume has been removed at craniotomy as judged from a pre/perioperative MRI
- Ability to understand the concept of investigational therapy
- Tolerates dexamethasone treatment
- Adequate anti-epileptic medication
- BNCT can be delivered within 6 weeks from the date of brain surgery
- A written informed consent
You may not qualify if:
- Age less than 18 or greater than 75
- The tumor infiltrates into the optic chiasm or into the deep parts of the brain prohibiting delivery of an adequate radiation dose with BNCT
- Prior radiation therapy to the brain
- Prior chemotherapy, immunotherapy, or gene therapy
- Karnofsky performance score \<70
- Severe cardiac, liver, or kidney failure
- Severe infection
- A cardiac pace-maker, or a metal implant in the head and neck region that will prohibit MRI examination
- Pregnancy or lactation
- Phenylketonuria
