OBJECTIVE The incidence of primary spinal cord glioblastoma multiforme (GBM) in the pediatric age group is very rare. Only a few case series and case reports have been published in the literature; therefore, overall survival (OS) outcome and the as-yet poorly defined management options are not discussed in detail. The authors performed a cumulative survival analysis of all reported cases of pediatric spinal cord GBM to identify the predictive factors related to final survival outcome. METHODS A comprehensive search for relevant articles was performed on PubMed's electronic database MEDLINE for the period from 1950 to 2015 using the search words "malignant spinal cord tumor" and "spinal glioblastoma multiforme...

The spinal glioblastoma (GBM) represents the one of most common tumors in humans. However, the biological processes and molecular mechanisms of spinal GBM are still unclear. It is known that miR-143 participates in the development of various tumor progressions. The present study was to evaluate the level of miR-143 in spinal GBM tissues and cells. We further investigated that the molecular mechanisms of miR-143 in U87 and U251 cell lines. Here, our data showed that the expression levels of miR-143 were significantly reduced in spinal GBM tissues and cell lines...

BACKGROUND: Primary intramedullary spinal cord glioblastoma are very rare tumors of the spinal cord. They imply a very poor prognosis since complete surgical resection is not possible due to the infiltrative growth of these tumors. The aim of this study is to present our data achieved with an aggressive multimodality treatment. METHODS: We retrospectively reviewed our clinical database. All patients with histologically proven intramedullary spinal cord glioblastoma treated in our department were included in this study...

Glioblastoma multiforme (GBM) is the most common and the most malignant primary intracranial tumor in adults and it is usually occurs between the age of 40 and 60 years. It is local invasive and recurrent tumor and hence that has a poor prognosis. However, recent advances in tumor surgery, irradiation and chemotherapeutic agent permit long survival and metastasis which is symptomatic. Previously studies reported spinal metastasis, but we report a first case of synchronous symptomatic cerebellar and cervical spinal metastasis after resection of symptomatic thoracic spinal metastasis from temporal GBM without any recurrence of excision areas...

We present the case of a patient with a left frontal glioblastoma with PNET features and hypermutated genotype in the setting of a POLE germline alteration. During standard-of-care chemoradiation, the patient developed a cervical spine metastasis and was subsequently treated with Pembrolizumab. Shortly thereafter, the patient developed an additional metastatic spinal lesion. Using whole exome DNA sequencing and clonal analysis, we report changes in the subclonal architecture throughout treatment. Furthermore, a persistently high neoantigen load was observed within all tumors...

KCa3.1 protein is part of a heterotetrameric voltage-independent potassium channel, the activity of which depends on the intracellular calcium binding to calmodulin. KCa3.1 is immensely significant in regulating immune responses and primarily expressed in cells of hematopoietic lineage. It is one of the attractive pharmacological targets that are known to inhibit neuroinflammation. KCa3.1 blockers mediate neuroprotection through multiple mechanisms, such as by targeting microglia-mediated neuronal killing. KCa3...

BACKGROUND: Glioblastoma multiforme (GBS) is a highly malignant glioma that rarely presents as an infratentorial tumor. Multicentric gliomas lesions are widely separated in site and/or time and its incidence has been reported between 0.15 and 10%. Multicentric gliomas involving supratentorial and infratentorial region are even more rare. In most cases, infratentorial disease is seen after surgical manipulation or radiation therapy and is usually located in the cerebellum or cervical region...

Primary central nervous system lymphoma (PCNSL) is an uncommon variant of extranodal non-Hodgkin lymphoma, which involves the brain, leptomeninges, eyes, or spinal cord without evidence of systemic disease. In addition to a detailed history and physical examination, the evaluation of patients suspected of having a PCNSL should include a contrast-enhanced magnetic resonance imaging. Occassionaly, PCNSL shows peculiarities on magnetic resonance imaging, which delay the diagnosis and thus the start of treatment...

Oxidative stress plays a critical role in various neurodegenerative diseases, thus alleviating oxidative stress is a potential strategy for therapeutic intervention and/or prevention of neurodegenerative diseases. In the present study, alleviation of oxidative stress through curcumin is investigated in A172 (human glioblastoma cell line) and HA-sp (human astrocytes cell line derived from the spinal cord) astrocytes. H2O2 was used to induce oxidative stress in astrocytes (A172 and HA-sp). Data show that H2O2 induces activation of astrocytes in dose- and time-dependent manner as evident by increased expression of GFAP in A172 and HA-sp cells after 24 and 12h respectively...

Pediatric spinal cord glioblastoma multiforme is a rare entity with a poor prognosis often presenting with lower extremity weakness or paralysis. Previous literature suggests that aggressive surgical resection may provide overall survival benefit; however, there is limited concurrent analysis demonstrating neurological recovery following surgical resection. We report the case of a 9-year-old boy who presented with complete paraplegia and regained the ability to ambulate independently following subtotal surgical resection, radiation, and chemotherapy...

RNA editing is increasingly recognized as a molecular mechanism regulating RNA activity and recoding proteins. Here we surveyed the global landscape of RNA editing in human brain tissues and identified three unique patterns of A-to-I RNA editing rates during cortical development: stable high, stable low and increasing. RNA secondary structure and the temporal expression of adenosine deaminase acting on RNA (ADAR) contribute to cis- and trans-regulatory mechanisms of these RNA editing patterns, respectively...

Glioblastoma multiforme (GBM) is one of the most common and aggressive primary brain tumors, composing 12-20% of all the intracranial tumors in adults with a highly malignant course and average life expectancy of approximately 12-14 months following initial diagnosis. Leptomeningeal or intramedullary metastasis from primary GBM is a rare phenomenon with a poor prognosis. We present a rare case of GBM with late onset intramedullary, extramedullary, as well as leptomeningeal spinal metastasis.

High-grade gliomas of the spinal cord represent a rare entity in children. Their biology, behavior, and controversial treatment options have been discussed in a few pediatric cases. These tumors are associated with severe disability and poor prognosis. We report a case of a 4-year-old child diagnosed with an isolated glioblastoma multiforme of the conus medullaris. The patient underwent subtotal surgical excision, followed by adjuvant radiotherapy and oral chemotherapy. He is alive with mild neurologic deficits at 52 months after diagnosis...

Gliosarcoma (GS) is a rare and exceedingly malignant neoplasm of the central nervous system. It displays clinical features similar to glioblastoma, yet is histologically unique as it harbors both gliomatous and sarcomatous cellular components. Involvement of the neuro-axis is predominantly limited to the cerebral parenchyma and meninges. Primary GS of the spinal cord is rarely encountered. We report a case of a 54 year old male who presented with 2 months of progressive, bilateral lower extremity sensory deficits...

PURPOSE: The objective of this study was to evaluate clinical significance and immunosuppressive mechanisms of B7-H4 (B7x/B7S1), a B7 family member, in glioma. EXPERIMENTAL DESIGN: B7-H4 levels in glioma tissue/cerebral spinal fluid (CSF) were compared between different grades of glioma patients. Survival data were analyzed with Kaplan-Meier to determine the prognostic value of B7-H4. Cytokines from CD133(+) cells to stimulate the expression of B7-H4 on human macrophages (Mφs) were investigated by FACS, neutralizing antibodies, and Transwell chemotaxis assay...
