Investigations of the effects of radiation on neuropsychological functions have revealed variable outcomes, ranging from no effect to severe cognitive impairment. However, many of the previous studies have relied on retrospective data or have been limited by methodological problems. In this study, prospective neuropsychological assessments were compared at(More)
Patients and relatives experiences of behavioural and personality changes following brain tumour were assessed to determine whether these changes are more prominent in the experience of patients with frontal tumours and their relatives as a first step to evaluate the need to develop appropriate support and management of such changes, which have a(More)
In ENU induced rat glioma model, the location of tumor is unpredictable and serial observation of neoplastic changes in a single lesion is not possible. We induced neoplastic transformation of cultured type-I astrocyte (AS-l) by exposure to ENU and observed the morphological changes of them. Since the importance of p53 alteration is stressed in human glial(More)
Background:Over the last decade, the approach to the management of brain tumours and the understanding of glioblastoma tumour biology has advanced and a number of therapeutic interventions have evolved, some of which have shown statistically significant effects on overall survival (OS) and progression-free survival in glioblastoma. The aim of this study is(More)
Background: MGMT methylation, along with 1p/19q co-deletion and IDH1 mutation, is an important biomarker in high grade gliomas. MGMT methylation indicates an improved response to temozolomide chemotherapy; patients with 1p/19q co-deleted anaplastic oligodendrogliomas benefit preferentially from adjuvant chemotherapy. Pyrosequencing is a method that allows(More)
BACKGROUND Glioblastoma multiforme with an oligodendroglial component (GBMO) has been recognized in the World Health Organization classification-however, the diagnostic criteria, molecular biology, and clinical outcome of primary GBMO remain unclear. Our aim was to investigate whether primary GBMO is a distinct clinicopathological subgroup of GBM and to(More)
