BNCT to Treat Glioma That Has Progressed Following Radiotherapy
Glioblastoma, Anaplastic Astrocytoma
About this trial
This is an interventional treatment trial for Glioblastoma focused on measuring glioblastoma, anaplastic astrocytoma, boron neutron capture therapy, radiation therapy, boronophenylalanine
Eligibility Criteria
Inclusion Criteria: Histologically confirmed supratentorial glioblastoma or anaplastic astrocytoma. Recurred tumor after surgery and radiotherapy or tumor progressing after radiotherapy.
