Therapeutic efficacy of Holmium siloxane in microbrachytherapy of induced glioblastoma in minipig tumor model.

Glioblastoma is considered the most common malignant primary tumor of central nervous system. In spite of the current standard and multimodal treatment, the prognosis of glioblastoma is poor. For this reason, new therapeutic approaches need to be developed to improve the survival time of the glioblastoma patient.
