Astrocytoma

Astrocytom

Svensk definition

En väl differentierad gliomform bestående av tumörceller av astrocyttyp, med varierande mängd fibrillärt stroma. Ett vanligt klassificeringssystem för dessa tumörer bygger på graden av malignitet (gra d I-IV). Hos personer yngre än 20 år uppkommer astrocytom vanligen i lillhjärnan; hos vuxna uppstår tumörerna oftast i cerebrum, ibland med snabb och utbredd tillväxt.

Engelsk definition

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.
