• Longitudinal mutational analysis of a cerebellar pilocytic astrocytoma recurring as a ganglioglioma. (cdc.gov)
  • In order to find progenitor cells that could give rise to hypothalamo-chiasmatic pilocytic astrocytomas, we performed a morphological study of the hypothalamo-chiasmatic region and identified, in the floor of the third ventricle, a unique population of vimentin- and glial fibrillary acidic protein-positive cells highly suggestive of radial glia cells. (ed.gov)
  • Some pilocytic astrocytomas may be more fibrillary and dense in composition. (wikipedia.org)
  • Patients diagnosed with pilocytic astrocytoma between 1973 and 2008 were identified in the National Cancer Institute Surveillance, Epidemiology, and End Results Program database. (springer.com)
  • This PDQ cancer information summary for health professionals provides comprehensive, peer-reviewed, evidence-based information about the treatment of childhood astrocytomas. (oncolink.org)
  • Numerous genes upregulated in hypothalamo-chiasmatic pilocytic astrocytomas also increased in the developing chiasm, suggesting that developmental genes mirror the cell of origin whereas migrative, adhesive and proliferative genes reflect infiltrative properties of these tumours. (ed.gov)
  • Dirven CM, Mooij JJ, Molenaar WM (1997) Cerebellar pilocytic astrocytoma: a treatment protocol based upon analysis of 73 cases and a review of the literature. (springer.com)
  • Expert-reviewed information summary about the treatment of childhood astrocytomas. (oncolink.org)
  • Understanding the molecular basis responsible for the aggressive behaviour of hypothalamo-chiasmatic pilocytic astrocytomas is a prerequisite to setting up new molecular targeted therapies. (ed.gov)
  • MY greatest concern is that 6 years ago she also had a cerebellar pilocytic astrocytoma removed. (medhelp.org)
  • Therefore, pilocytic astrocytomas of the hypothalamo-chiasmatic region should be considered as a distinct entity which probably originates from a unique population of cells with radial glia phenotype. (ed.gov)
