“1. Introduction Human gliomas are the most common primary intracranial tumors in adults. A grading scheme proposed by the WHO distinguishes four different grades of gliomas, of which glioblastoma multiforme (GBM) WHO grade IV is the most malignant variant with a median survival time of 1 year [1].
