Central nervous system (CNS) tumors are the most common solid tumors in childhood. Since the sensitivity of combined cerebrospinal fluid (CSF) cytology and radiological neuroimaging in detecting meningeal metastases remains relatively low, we sought to characterize the CSF proteome of patients with CSF tumors to identify biomarkers predictive of metastatic spread. CSF samples from 27 children with brain tumors and 13 controls (extra-CNS non-Hodgkin lymphoma) were processed using core-shell hydrogel nanoparticles, and analyzed with reverse-phase liquid chromatography/electrospray tandem mass spectrometry (LC-MS/MS)...

Low-grade gliomas are one of the most common brain tumors in children, where they frequently form within the optic pathway (optic pathway gliomas; OPGs). Since many OPGs occur in the context of the Neurofibromatosis Type 1 (NF1) cancer predisposition syndrome, we have previously employed Nf1 genetically-engineered mouse (GEM) strains to study the pathogenesis of these low-grade glial neoplasms. In the light of the finding that human and mouse low-grade gliomas are composed of Olig2+ cells and that Olig2+ oligodendrocyte precursor cells (OPCs) give rise to murine high-grade gliomas, we sought to determine whether Olig2+ OPCs could be tumor-initiating cells for Nf1 optic glioma...

Embryonal tumors are a heterogeneous group of central nervous system (CNS) tumors whose subgroups have varying incidence and outcome. Despite these differences, they are often grouped as a single entity for study purposes. To date, there are no Canadian multi-institutional studies examining the incidence and outcome of all embryonal subtypes. The current study is an observational study reviewing embryonal tumors in all patients less than 36 months of age diagnosed with a CNS tumor in Canada from 1990 to 2005...

Tuberous sclerosis is an autosomal dominant disorder with a wide clinical spectrum of disease. It is characterized by development of benign tumors in multiple organs due to a disturbance in cellular growth and differentiation. It usually affects skin, brain, heart and kidney. Gastrointestinal involvement is rare and mainly restricted to adults and sigmoid colon and rectum. In children there are only two cases; our patient would be the third. We present a patient with tuberous sclerosis who began at the first month of life with repeated intestinal subocclusion...

The use of digital technology has grown rapidly during the last couple of decades. During use, mobile phones and cordless phones emit radiofrequency (RF) radiation. No previous generation has been exposed during childhood and adolescence to this kind of radiation. The brain is the main target organ for RF emissions from the handheld wireless phone. An evaluation of the scientific evidence on the brain tumor risk was made in May 2011 by the International Agency for Research on Cancer at World Health Organization...

Exophytic pontine glioblastoma multiforme (GBM) is a highly malignant tumor of posterior fossa, which is quite rare and such tumor presenting as cerebellopontine (CP) angle mass is even rarer. Here, we describe a 12-year-old boy who presented with imbalance on walking and facial nerve paresis. Magnetic resonance imaging of the brain revealed an irregular ring enhancing mass lesion of the CP angle, which was initially thought to be a tuberculoma, but was later confirmed to be a GBM. Clinical and radiological differentiation of uncommon lesions of CP angle in children is discussed with brief review of pertaining literature...

Over 4 million children in the United States suffer from chronic health conditions, including cancer, sickle cell disease, and diabetes. Because of major advances in the early identification and treatment of these conditions, survival rates for these children continue to rise, and the majority now lives into adulthood. However, increases in survival have come with costs related to long-term effects of disease processes and treatments. Foremost among these consequences is impairment in brain development and neurocognitive function that may affect a substantial portion of children with chronic health conditions and follow many into adulthood...

Primitive neuroectodermal tumors (PNETs) are highly malignant neoplasms of embryonal origin manifesting in children and adolescents, rarely seen in adults. Carcinoma lung with hemorrhagic metastasis to the brain is very common, but primary lung PNET with hemorrhagic brain metastasis is extremely uncommon. We hereby report a 29-year-old female diagnosed as PNET lung was treated with vincristine, adriamycin, and cyclophosphamide alternating with ifosfamide plus etoposide followed by radiotherapy (RT). After 9 months, she developed hemorrhagic brain metastasis from PNET lung confirmed from tissue immunohistology postcraniotomy...

Human gliomas are a heterogeneous group of primary malignant brain tumors, which most commonly occur in the central nervous system of children and adults. Previous studies have suggested a prognostic role of matrix metalloproteinase 9 (MMP9) in glioma, however, the frequency and significance of the protein expression of MMP9 in glioma remain to be fully elucidated. In the present study, the expression of MMP9 was detected by reverse transcription-quantitative polymerase chain reaction (qPCR), western blotting and immunohistochemical staining...
