Description

Glioblastoma Multiforme (GBM) is biologically aggressive neoplasms which have an elevated, often aberrant, proliferative capacity with a diffuse pattern of brain invasion. It is the most malignant Astrocytic tumor, composed of poorly differentiated neoplastic astrocytes (Ref.1). The World Health Organization (WHO) grading system classifies Gliomas into Grades I-IV based on the degree of malignancy, as determined by histopathological criteria. In the Central Nervous System (CNS), Grade-I Gliomas generally behave in a benign fashion and might even be circumscribed, whereas Grade-II, Grade-III and Grade-IV Gliomas are malignant and diffusely infiltrate throughout the brain. Glioblastoma Multiforme falls under the Grade-IV category. Glioblastoma Multiforme or the WHO Grade-IV Astrocytoma is divided into two subtypes based on clinical characteristics: Primary and Secondary GBM. Primary [...]
