Role of endothelial-to-mesenchymal transition in the pathogenesis of central nervous system hemangioblastomas.

Hemangioblastomas (HBs) are benign vascular tumors of the central nervous system and histologically contain abundant microvessels. Therefore, they clinically exhibit vascular malformation-like characteristics. It has been described that endothelial-to-mesenchymal transition (EndMT) contributes to the pathogenesis of cerebral cavernous malformations. However, it remains unknown whether EndMT contributes to the pathogenesis of central nervous system HBs. The aim of our study was to investigate whether EndMT o...


Primary Tumors of the Central Nervous System. Clinical Experience at a Third Level Center.

Central nervous system (CNS) tumors are a group of neoplasms that originate from various cells in the CNS. The increasing incidence and prevalence of this type of tumor in developing countries are striking; however, there are few current studies in Latin America including Mexico estimating the impact of these pathological entities on the general population.

The purpose of this study was to examine the prevalence and predictors of social difficulties in adolescent survivors of central nervous system (CNS) tumors.

Serum VEGF-A concentrations in patients with central nervous system (CNS) tumors.

Angiogenesis plays an essential role in tumors development. In case of central nervous system tumors, the most important role in this process plays VEGF-A. The purpose of this study was to determine the plasma concentration of this agent in patients treated surgically because of intracranial tumors. The study involved 48 adult patients, both sexes, treated surgically because of a brain tumor. The control group consisted of 50 adult volunteers of both sexes, without cancer diagnosis. Based on the studies, it...

Multiple cerebral gliomas mimicking central nervous system inflammatory demyelinating diseases: A rare case with review of literature.

Multiple cerebral gliomas (MCGs), usually classified into multifocal and multicentric subtypes, represent major diagnostic challenges as their clinical, radiologic, and pathohistological features are not uniform, often mimicking brain metastatic tumors or central nervous system inflammatory demyelinating diseases (IDD).

Primary central nervous system lymphoma in a patient with systemic lupus erythematosus mimicking high-grade glioma: A case report and review of literature.

Primary central nervous system lymphoma (PCNSL) is a rare disease. Studies of PCNSL in patients with rheumatic diseases are lacking. Neither clinical symptoms nor radiographic manifestation is specific to PCNSL. Therefore, it could be misdiagnosed with other diseases such as brain tumors. Chemotherapy is the primary treatment for PCNSL, while the role of surgery remains controversial.

Re-induction chemotherapy regimens in patients with recurrent central nervous system mixed malignant germ cell tumors.

The lack of a standard treatment approach has contributed to poor outcomes of patients with recurrent central nervous system (CNS) mixed malignant germ cell tumors (MMGCT). There are no data in the literature supporting optimal re-induction chemotherapy regimens that should be used for patients with recurrent CNS MMGCT.

INSM1 Expression Is Frequent in Primary Central Nervous System Neoplasms but Not in the Adult Brain Parenchyma.

Tumors with a neuronal component comprise a small percentage of central nervous system (CNS) neoplasms overall, but the presence of neuronal differentiation has important diagnostic, prognostic, and therapeutic implications. Insulinoma-associated protein 1 (INSM1) is a transcription factor with strong nuclear immunostaining in neuroendocrine cells and neoplasms of neuroendocrine origin; however, its expression in the CNS in normal brain and in neoplastic cells has not been fully explored. Here, we present i...

Glia-neuron energy metabolism in health and diseases: New insights into the role of nervous system metabolic transporters.

The brain is, by weight, only 2% the volume of the body and yet it consumes about 20% of the total glucose, suggesting that the energy requirements of the brain are high and that glucose is the primary energy source for the nervous system. Due to this dependence on glucose, brain physiology critically depends on the tight regulation of glucose transport and its metabolism. Glucose transporters ensure efficient glucose uptake by neural cells and contribute to the physiology and pathology of the nervous syste...

Diffusion and perfusion MR patterns of central nervous system lymphomas.

Central nervous system lymphomas (CNSLs) are rare tumors which may show variable appearance in standard magnetic resonance imaging (MRI) depending on their origin (primary or secondary) or patients' immunological status.

Malignant invasion of the central nervous system: the hidden face of a poorly understood outcome of prostate cancer.

Malignancies of the central nervous system include primary brain tumors and brain metastases, the latter being the major cause of intracranial neoplasms in adults. Although prostate cancer (PCa) brain metastases are not the most common source, recent data show that the relevance of prostate cancer brain metastases (PCBM) cannot be neglected. In this review, we focus on the molecular repertory as well as on the phenotypical similarities between PCBM and primary PCa, such as the cellular evolution and the mai...

Ibrutinib brain distribution: a preclinical study.

Central nervous system (CNS) dissemination occurs in 4.1% of mantle cell lymphoma (MCL) patients and clinically significant CNS involvement in chronic lymphocytic leukemia (CLL) patients reaches 4%. Ibrutinib, an orally administered Bruton's tyrosine kinase (BTK) inhibitor, has shown substantial activity in CLL or MCL patients with CNS localization, and in primary central nervous system lymphoma (PCNSL). The drug efficacy to treat primary or secondary CNS impairments relies on its brain distribution through...

A phase 1/2 dose-finding, safety, and activity study of cabazitaxel in pediatric patients with refractory solid tumors including tumors of the central nervous system.

This phase 1/2 study (NCT01751308) evaluated cabazitaxel in pediatric patients. Phase 1 determined the maximum tolerated dose (MTD) in patients with recurrent/refractory solid tumors, including central nervous system (CNS) tumors. Phase 2 evaluated activity in pediatric recurrent high-grade glioma (HGG) or diffuse intrinsic pontine glioma (DIPG).

Brain neurotransmitter transporter/receptor genomics and efavirenz central nervous system adverse events.

We characterized associations between central nervous system (CNS) adverse events and brain neurotransmitter transporter/receptor genomics among participants randomized to efavirenz-containing regimens in AIDS Clinical Trials Group studies in the USA.

Intraoperative Transpedicular Onyx Injection to Reduce Vascularity of a Thoracic Hemangiopericytoma After Unsuccessful Preoperative Endovascular Embolization: a Technical Report.

Hemangiopericytoma is a rare vascular tumor with central nervous system involvement representing only 1% of central nervous system tumors. They rarely affect the vertebral column. Complete surgical resection is the treatment of choice for hemangiopericytoma given their high rates of local recurrence. However, the high vascularity of such tumors with the risk of massive bleeding during surgery represents a significant challenge to surgeons. Therefore, preoperative endovascular embolization via the transarter...

Neuroinflammation and Central Sensitization in Chronic and Widespread Pain.

Chronic pain is maintained in part by central sensitization, a phenomenon of synaptic plasticity, and increased neuronal responsiveness in central pain pathways after painful insults. Accumulating evidence suggests that central sensitization is also driven by neuroinflammation in the peripheral and central nervous system. A characteristic feature of neuroinflammation is the activation of glial cells, such as microglia and astrocytes, in the spinal cord and brain, leading to the release of proinflammatory cy...

Increased incidence of inguinal hernia in offspring of female survivors of childhood central nervous system tumors.

Female survivors of childhood central nervous system (CNS) tumors experience an increased risk of infertility and various pregnancy complications. We aimed to explore whether the incidence of inguinal hernia could be higher in offspring of female CNS tumor survivors as compared to the general population. Girls who were younger than 15 years of age and diagnosed with CNS tumors between 1958 and 2013 were identified from the Swedish Cancer Registry. By linking with the Swedish Medical Birth Registry, we ident...

A brain within the heart: A review on the intracardiac nervous system.

Cardiac function is under the control of the autonomic nervous system, composed by the parasympathetic and sympathetic divisions, which are finely tuned at different hierarchical levels. While a complex regulation occurs in the central nervous system involving the insular cortex, the amygdala and the hypothalamus, a local cardiac regulation also takes place within the heart, driven by an intracardiac nervous system. This complex system consists of a network of ganglionic plexuses and interconnecting ganglio...

Surgical Treatment of Spinal Ependymomas: Experience in 49 Patients.

Ependymomas are rare tumors of the central nervous system. The local tumor distribution in the central nervous system is highly age-dependent as among adults ependymomas occur mostly in the spinal cord, whereas among children intracranial manifestations are more common. To date, there are no prospective studies about treatment strategies for ependymomas. In most cases complete tumor resection is recommended. The role of radiation therapy in low-grade ependymomas remains unclear.

Carbonic anhydrase related protein expression in astrocytomas and oligodendroglial tumors.

Carbonic anhydrase related proteins (CARPs) VIII, X and XI functionally differ from the other carbonic anhydrase (CA) enzymes. Structurally, they lack the zinc binding residues, which are important for enzyme activity of classical CAs. The distribution pattern of the CARPs in fetal brain implies their role in brain development. In the adult brain, CARPs are mainly expressed in the neuron bodies but only weaker reactivity has been found in the astrocytes and oligodendrocytes. Altered expression patterns of C...

Toward methylation-based classification of central nervous system tumors.

Risk of central nervous system defects in offspring of women with and without mental illness.

We sought to determine the relationship between maternal mental illness and the risk of having an infant with a central nervous system defect. We analyzed a cohort of 654,882 women aged less than 20 years between 1989 and 2013 who later delivered a live born infant in any hospital in Quebec, Canada. The primary exposure was mental illness during pregnancy or hospitalization for mental illness before pregnancy. The outcomes were neural and non-neural tube defects of the central nervous system in any offspri...

Quantification of the Central Cardiovascular Network Applying the Normalized Short-time Partial Directed Coherence Approach in Healthy Subjects.

The central control of the autonomic nervous system (ANS) and the complex interplay of its components can be described by a functional integrated mode - the central autonomic network (CAN). CAN represents the integrated functioning and interaction between the central nervous system (CNS) and ANS (parasympathetic and sympathetic activity).

The Impact of Early Corticosteroid Pretreatment Before Initiation of Chemotherapy in Patients With Primary Central Nervous System Lymphoma.

The optimal timing of corticosteroid (CS) treatment in patients with primary central nervous system (CNS) lymphoma (PCNSL) remains controversial. While poor clinical presentation may justify early treatment with CS, this may ultimately result in reduced concentrations of chemotherapeutic agents via perturbations in the permeability of the blood-brain barrier.
