Glioblastoma multiforme (GBM) is a high-grade gliomas and the most malignant astrocytic tumor, composed of complexly differentiated neoplastic astrocytes, a subtype of central nervous system (CNS). Glioblastoma is clinically classified as grade IV astrocytoma and differs from anaplastic astrocytoma (grade III) due to the presence of necrotic tissue and hyperplastic blood vessels. The diagnosis of GBM is carried out with imaging modules such as computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET). In case of GBM treatment, there are many restraints and challenges such as its resistance against DNA-modifying agents, migration of malignant cells into adjacent brain tissues increases the complexity of the surgery, and current FDA approved treatments may cause neurotoxicity in patients. Thus, as available treatment options lack in efficiency, the mortality rate of glioblastoma is characterized by rapid progression and poor survival rate with only 8.7% of the patients surviving more than two years post diagnosis. According to Centers for Disease Control and Prevention (CDC), in 2011, approximately 22,000 adults in the U.S. were diagnosed with primary malignant tumors of the brain and spinal cord out of which gliomas accounted for the highest rate of incidence.
