BACKGROUND: Few studies in North America have quantified the risks of second malignant neoplasms (SMNs) among survivors of childhood non-central nervous system (non-CNS) embryonal tumours due to their rarity. We aimed to investigate these risks by combining population-based data from the United States of America and Canada. METHODS: We evaluated patients with childhood non-CNS embryonal tumours reported to the Surveillance Epidemiology and End Results program and eight Canadian cancer registries from 1969 to 2010...

Melatonin (MEL) has promising medicinal value as an anticancer agent in a variety of malignancies, but there are difficulties in achieving a therapeutic dose due to its short half-life, low bioavailability, poor solubility and extensive first-pass metabolism. In this study chitosan/tripolyphosphate (TPP) nanoparticles were prepared by an ionic gelation method to overcome the therapeutic challenges of melatonin and to improve its anticancer efficacy. Characterization of the melatonin-loaded chitosan (MEL-CS) nanoformulation was performed using transmission and scanning electron microscopies, dynamic light scattering, Fourier transform infrared spectroscopy, Raman spectroscopy and x-ray diffraction...

BACKGROUND: PET using O-(2-[(18)F]fluoroethyl)-L-tyrosine ((18)F-FET) is an established method for brain tumour diagnostics, but data processing varies in different centres. This study analyses the influence of methodological differences between two centres for tumour characterization with (18)F-FET PET using the same PET scanner. Methodological differences between centres A and B in the evaluation of (18)F-FET PET data were identified for (1) framing of PET dynamic data, (2) data reconstruction, (3) cut-off values for tumour delineation to determine tumour-to-brain ratios (TBR) and tumour volume (Tvol) and (4) ROI definition to determine time activity curves (TACs) in the tumour...

Glioblastoma multiforme (GBM) are mortifying brain tumours that contain a subpopulation of tumour cells with stem-like properties, termed glioblastoma stem-like cells (GSCs). GSCs largely contribute to tumour initiation, propagation and resistance to current anti-cancer therapies. GSCs are situated in perivascular niches, closely associated with brain microvascular endothelial cells, thereby involved in bidirectional molecular and cellular interactions. Moreover, extracellular vesicles are suspected to carry essential information that can adapt the microenvironment to the tumour's needs, including tumour-induced angiogenesis...

BACKGROUND: Meningioma is the commonest primary intracranial tumour in adults. Excision is curative for low grade meningioma, whereas high-grade meningioma requires adjuvant therapy following surgery. Several studies have examined the association between peritumoural brain Edema - a common feature in meningioma - and histological grading with mixed results. The present study attempted to elucidate this association and if peritumoural brain Edema affects the intra-operative judgement of surgeons on the completeness of resection...

Glioblastoma (GBM) is the most aggressive and common malignant brain tumour in adults. A well-known hallmark of GMB and many other tumours is aerobic glycolysis. MicroRNAs (miRNAs) are a class of short nonprotein coding sequences that exert posttranscriptional controls on gene expression and represent critical regulators of aerobic glycolysis in GBM. In GBM, miRNAs regulate the expression of glycolytic genes directly and via the regulation of metabolism-associated tumour suppressors and oncogenic signalling pathways...

AIMS: Creutzfeldt-Jakob disease (CJD) risk precautions are required when performing brain biopsies on patients with a dementing illness and in 'risk' groups. The impact on a diagnostic neuropathology service is considerable. We sought to determine if better case selection might reduce the necessity for application of CJD risk precautions. METHODS: We reviewed the clinical information, contributory investigations and final neuropathologic diagnosis in a cohort of patients (n = 21), referred to the National CJD Surveillance Centre between January 1, 2005, and December 31, 2016...

INTRODUCTION: For ill children as well as for their parents and siblings, childhood cancer poses a major challenge. Little is known about the reintegration into daily life of childhood cancer survivors and their families. The aim of this prospective observational study is to further the understanding of the role of rehabilitation measures in the reintegration process of childhood leukaemia or brain tumour survivors and their family members after the end of cancer treatment. METHODS AND ANALYSIS: This prospective observational study consists of three study arms: a quantitative study in cooperation with three German paediatric oncological study registries (study arm 1), a quantitative study in cooperation with a rehabilitation clinic that offers a family-oriented paediatric oncological rehabilitation programme (study arm 2) and a qualitative study at 12-month follow-up including families from the study arms 1 and 2 (study arm 3)...

Renal cell carcinoma accounts for 3% of all adult malignancies. Usual sites of metastasis are lymph nodes, lungs, bone, liver and brain. We describe a patient who presented with complaints of holocranial headache and diplopia. MRI of the head showed a clival-based lesion with associated bony erosion. With suspicion of a metastatic lesion, an ultrasonogram of the abdomen was done which showed a left renal mass that enhanced on contrast-enhanced CT. There were no other metastatic foci. Patient underwent radiotherapy for the clival lesion...

Tailored nanocarriers have gained huge research focus for brain drug delivery, aimed at combating several neuro-oncological conditions, such as the glioblastoma multiforme (GBM). The progress of knowledge on the pathogenesis of GBM has allowed identifying the major hurdles for efficient treatment, encompassing biological interfaces (blood-brain barrier and blood-brain tumour barrier), specificities of tumour microenvironment, as well as both bulk and glioma stem cell subpopulations. These findings provided new insights into the molecular basis of GBM, being a strong driving force behind development of targeted nanomedicines in this area...

REVIEW
W-D Heiss
Neuroimaging plays a significant role in the diagnosis of intracranial tumours, especially brain gliomas, and must consist of an assessment of location and extent of the tumour and of its biological activity. Therefore, morphological imaging modalities and functional, metabolic or molecular imaging modalities should be combined for primary diagnosis and for following the course and evaluating therapeutic effects. Magnetic resonance imaging (MRI) is the gold standard for providing detailed morphological information and can supply some additional insights into metabolism (MR spectroscopy) and perfusion (perfusion-weighted imaging) but still has limitations in identifying tumour grade, invasive growth into neighbouring tissue and treatment-induced changes, as well as recurrences...

BACKGROUND: The role of the dominant hippocampus in verbal and episodical memory recall had been extensively investigated. However, there are categories of memory estimated independent of hippocampal function. Particularly, factual knowledge is solely constituted from written or spoken input independent from undertaken experience, but the temporal structures involved are not well defined yet. METHODS: In this retrospective study we mapped the activity of factual knowledge recall using functional MR imaging in 60 patients scheduled for tumour or epilepsy surgery and in 18 patients resected within or close to the left mesial temporal lobe...

Histone deacetylase (HDAC) inhibitors prevent neural cell death in in vivo models of cerebral ischaemia, brain injury and neurodegenerative disease. One mechanism by which HDAC inhibitors may do this is by suppressing the excessive inflammatory response of chronically activated microglia. However, the molecular mechanisms underlying this anti-inflammatory effect and the specific HDAC responsible are not fully understood. Recent data from in vivo rodent studies has shown that inhibition of class I HDACs suppresses neuroinflammation and is neuroprotective...

Combined central and peripheral demyelination (CCPD) is a rare chronic inflammatory disorder of the nervous system. We describe the case of a patient with a history of recurrent myelitis that acutely and simultaneously developed a brain tumour-like lesion and a sensitive-motor demyelinating polyneuropathy. The diagnosis of CCPD was supported by a detailed diagnostic workup. Up to date, no similar cases have been reported in the literature.

The paraneoplastic limbic encephalitis is a rare disease. It is caused by the presence of autoantibodies creating an inflammatory reaction of the predominant brain parenchyma in the meso-temporal lobe and in other parts of the limbic system. Its presence requires looking for an underlying tumour. The management of this paraneoplastic syndrome includes an immunosuppressive therapy in addition to the treatment of the underlying tumour. However, the management of this disease is not yet standardized.

To assess the impact of CD133 expression on the prognosis of endometrioid endometrial carcinoma (EEC). We retrospectively assessed CD133 expression in tissue microarray of 116 surgically treated FIGO I-III EEC. Tumors with ≥10% of CD133-expressing cells were considered CD133-positive (CD133+). On the basis of CD133 expression, clinical and pathological parameters, progression-free survival (PFS) and overall survival (OS) were evaluated. Of the EEC studied 85.2% showed CD133-expressing cells. Only 61% (n = 66) of EEC presented ≥10% of CD133 expressing cells and were considered CD133+...
