BACKGROUND IDH1/2 mutation, 1p/19q-codeletion and MGMT hypermethylation are well known molecular markers for gliomas. ATRX and p53 alterations are two lineage-specific genetic aberrations in diffuse astrocytic tumors. The aim of the present study is to clarify the significance of ATRX loss and its correlation with p53 overexpression, IDH1/2 mutations,(More)
OBJECTIVE To investigate mutation status of isocitrate dehydrogenase (IDH) 1 and IDH2 genes in Chinese patients with gliomas in correlation with clinicopathological characteristics. METHODS Formalin-fixed and paraffin-embedded (FFPE) tissue samples of 234 gliomas were collected including the matched blood samples in 30 patients. DNA was extracted,(More)
Focal cortical dysplasia type IIB is a commonly encountered subtype of developmental malformation of the cerebral cortex and is often associated with pharmacoresistant epilepsy. In this study, to investigate the molecular etiology of focal cortical dysplasia type IIB, the authors performed micro ribonucleic acid (RNA) microarray on surgical specimens from 5(More)
We describe a rare case of gliosarcoma with primitive neuroectodermal, osseous, cartilage and adipocyte differentiation. A 57-year-old man experienced a month history of headache, nausea and vomiting. Worse yet, the headache has become more severe for the past 6 days. Magnetic resonance (MR) images disclosed a lesion with operative indications located in(More)
