BACKGROUND AND PURPOSE Only a few reports on intramedullary tumors of the spinal cord using PET have been published. We report findings of PET by using [(18)F] fluorodeoxyglucose and [(11)C] methionine and discuss the usefulness of the findings in patients with intramedullary tumors of the spinal cord. MATERIALS AND METHODS PET/CT was performed in 9 patients with intramedullary tumors of the ...

  Cellular estrogen receptors in cryostat sections of human glioma tissue were determined in 34 patients by a histochemical method with 17β-estradiol-6-carboxymethyl oxime-bovine serum albumin-fluorescein isothiocyanate conjugate. Estrogen receptor protein was found in all cases of glioblastoma multiforme (7), anaplastic astrocytoma (5), benign astrocytoma (7), pilocytic astrocytoma (...

A patient with multiple sclerosis and a multicentric anaplastic astrocytoma is described. The evidence suggests that the relationship is not coincidental and that the astrocytomas originate in multiple sclerosis plaques.

The balance between Th1 and Th2 cytokines is thought to be an important factor in terms of tumour prognosis. Serum samples from 61 newly diagnosed patients with brain tumours and 50 age- and sex-matched non-tumour controls were analysed by ELISA for circulating levels of interleukin-12 (IL-12p70 and p40) and interleukin-10 (IL-10); pivotal Th1 and Th2 cytokines, respectively. Patients were divi...

The present study investigated the altered expression of p2X purinoceptor (P2X7R) in astrocytoma. Reverse transcription-quantitative polymerase chain reaction and western blot analysis were used to determine the P2X7R expression in glioblastoma (GBM) and surrounding normal brain tissue. DNA methylation levels of P2X7R gene promoter in GBM were analyzed using a Sequenom MassARRAY® System. Immuno...

this report describes the case of a 56 year-old man with a history of diplopia. his brain imaging showed multiple lesions with a metastatic appearance, however all investigations to determine the primary source of malignancy were negative. the patient underwent a brain biopsy, which was positive for anaplastic astrocytoma, a rare tumor that should be considered in the differential diagnosis of ...

BACKGROUND There is at present no consensus on the policy for the treatment of patients with low-grade gliomas (LGGs). METHODS This report is a retrospective multi-institutional study of 100 patients (ages 16-65 years) with astrocytoma (grade II), oligodendroglioma, anaplastic oligodendroglioma and anaplastic oligoastrocytoma of the supratentorial areas which were treated with surgery and pos...

First identified in 2012, the histone 3 mutation H3.3K27M significantly affects the prognosis of children with anaplastic astrocytoma (AA) and other gliomas. Tumors with this mutation tend to be more aggressive and localize along the midline, behaving like diffuse intrinsic pontine gliomas (DIPGs). Surgical options are often limited because of the deep location of these tumors coupled with thei...

Loss of constitutional heterozygosity for specific chromosomal loci, when found consistently in a particular tumor type, suggests that a recessive oncogene important in the genesis of that tumor may be present within the involved chromosomal loci. DNA markers that detect restriction fragment length polymorphisms are powerful tools that have been used to detect loss of chromosomal loci in a grow...

INTRODUCTION Despite aggressive multidisciplinary interventions, patients with high-grade astrocytomas experience tumour progression or recurrence. Treatment for this group of patients remains a formidable challenge. We describe our experience of salvage chemotherapy for these patients. MATERIALS AND METHODS A retrospective review of relevant clinical and radiographic information of patients ...
