Neoplasms of the brain and spinal cord derived from glial cells which vary from histologically
benign forms to highly anaplastic and malignant tumors. Fibrillary astrocytomas are
the most common type and may be classified in order of increasing malignancy (grades
I through IV). In the first two decades of life, astrocytomas tend to originate in
the cerebellar hemispheres; in adults, they most frequently arise in the cerebrum
and frequently undergo malignant transformation. (From Devita et al., Cancer: Principles
and Practice of Oncology, 5th ed, pp2013-7; Holland et al., Cancer Medicine, 3d ed,
p1082)
