Supratentorial lobar pilocytic astrocytomas: report of 45 operated cases, including 9 recurrences

Abstract

45 cases with supratentorial, lobar--mainly temporo-parietal--pilocytic astrocytoma are analysed. The mostly highly vascularized tumours frequently present with histologically different tissue components. Formation of cysts of various size was found in 67%. The tumour usually ran a benign clinical course with a comparatively low incidence of recurrence. Malignant transformation of recurrent tumours was not observed. Radiotherapy of conventional dosage did not prove to have any influence on survival, neither post-operatively nor after re-operation. Transformation of persisting pluripotential cells of the subependymal periventricular plate after migration to the surface of the brain is being discussed as the origin of this variant of pilocytic astrocytoma.

Astrocytes

Astrocytes are glial cells that support the blood-brain barrier, facilitate neurotransmission, provide nutrients to neurons, and help repair damaged nervous tissues. Here is the latest research.
