Mitoses and necrosis are not associated with a worse prognosis. In view of the low proliferative indices and long survival of these patients without recurrence, the role of post-operative radiotherapy is questionable. These patients should be followed up closely as many of them develop stigmata of...
ASTROCYTOMASCYCLIN-dependent kinase inhibitorsISOCITRATE dehydrogenaseSIGNAL convolutionBackground: Cyclin‐dependent kinase inhibitor 2A/B (CDKN2A/B) homozygous deletion has been verified as an independent and critical biomarker of negative prognosis and short survival in isocitrate dehydrogenase (IDH)‐mutant...
As shown in Table 1, the higher expression of CASC2c also markedly correlated with clinical stage and death of patients, but it is not correlated with gender and age. To further examine the effect of expression of CASC2c on the survival of astrocytoma patients, we employed the Kaplan– ...
Differentially expressed proteins in this early stage, low-grade gliomas, include important regulatory proteins such as EGFR, HNRNP K and BCAN. Though not specific to DA they may be promising candidates for confirmatory diagnosis of these early stage tumors. We also provide a catalogue of ...

OBJECTIVES Intraventricular astrocytomas (subependymal giant cell astrocytomas) of tuberous sclerosis have a poor prognosis due to the obstruction of CSF flow. The aim of this study was to determine whether they could be differentiated during childhood and at an early preclinical stage, from sub...
