  • [Title] [Detection and clinical significance of urinary epidermal growth factor in brain tumor patients].
  • METHODS: The levels of EGF in urine samples collected from 20 patients (9 low grade astrocytomas, 6 anaplastic astrocytomas, and 5 meningiomas) and 5 healthy individuals were determined.
  • RESULTS: Preoperative urinary EGF levels of astrocytoma patients were statistically higher than those of meningioma patients and the controls (P < 0.01).
  • Preoperative urinary EGF levels showed a positive correlation with the degree of malignance in the astrocytoma patients (P < 0.05).
  • A significant decrease of the postoperative levels of EGF was observed in the astrocytoma patients who underwent gross total resection (P < 0.01).
  • CONCLUSION: The urinary EGF levels of astrocytoma patients correlate with the WHO grade of malignance and significantly decrease after gross total removal.
  • Urinary EGF may be of practical value in diagnosing and evaluating the surgical efficacy of astrocytomas.

  • [Title] Gene expression profiles of human glioblastomas are associated with both tumor cytogenetics and histopathology.
  • Despite the increasing knowledge about the genetic alterations and molecular pathways involved in gliomas, few studies have investigated the association between the gene expression profiles (GEP) and both cytogenetics and histopathology of gliomas.
  • Here, we analyzed the GEP (U133Plus2.0 chip) of 40 gliomas (35 astrocytic tumors, 3 oligodendrogliomas, and 2 mixed tumors) and their association with tumor cytogenetics and histopathology.
  • Unsupervised and supervised analyses showed significantly different GEP in low- vs high-grade gliomas, the most discriminating genes including genes involved in the regulation of cell proliferation, apoptosis, DNA repair, and signal transduction.
  • In turn, among glioblastoma multiforme (GBM), 3 subgroups of tumors were identified according to their GEP, which were closely associated with the cytogenetic profile of their ancestral tumor cell clones: (i) EGFR amplification, (ii) isolated trisomy 7, and (iii) more complex karyotypes.
  • In summary, our results show a clear association between the GEP of gliomas and tumor histopathology; additionally, among grade IV astrocytoma, GEP are significantly associated with the cytogenetic profile of the ancestral tumor cell clone.

  • [Title] Akt-dependent proapoptotic effects of dietary restriction on late-stage management of a phosphatase and tensin homologue/tuberous sclerosis complex 2-deficient mouse astrocytoma.
  • PURPOSE: Malignant astrocytomas exhibit constitutive Akt phosphorylation due to reduced phosphatase and tensin homologue (PTEN) tumor suppressor expression or to increased growth factor receptor tyrosine kinase activation.
  • Many astrocytomas are also tuberous sclerosis complex 2 (TSC2) protein deficient and exhibit constitutive mammalian target of rapamycin (mTOR) activity.
  • Astrocytomas harboring PTEN/Akt/TSC2 pathway mutations are dependent on glycolysis to satisfy their bioenergetic requirements.
  • Therapies that disrupt energy homeostasis can potentially manage astrocytoma growth and progression.
  • Although dietary restriction (DR) reduces glycolysis and manages early-stage astrocytoma growth, no prior studies have identified the mechanisms involved or determined if DR can also manage late-stage tumor growth.
  • EXPERIMENTAL DESIGN: The effects of a late-onset intermittent DR feeding paradigm were examined in adult C57BL/6J mice bearing the syngeneic CT-2A malignant astrocytoma grown orthotopically or subcutaneously.
  • DR initiated 10 to 14 days after tumor implantation (late onset) reduced CT-2A growth, delayed malignant progression, and significantly extended survival.
  • CONCLUSIONS: Our findings indicate that IGF-I/Akt signaling is associated with the antiapoptotic and glycolytic phenotype of the CT-2A astrocytoma and that DR targets this pathway.
  • Our findings highlight the efficacy of late-onset DR in managing astrocytoma growth and suggest that DR may be an effective broad-spectrum inhibitor of Akt signaling in PTEN/TSC2-deficient astrocytomas.

  • Polymorphisms in codon 72 of the p53 tumor suppressor gene have been associated with susceptibility to human cancer.
  • In this study, we scored 135 brain tumor samples (92 adult and 43 pediatric cases consisting of 64 high-grade astrocytomas and 71 non-astrocytomas) for the P53 Arg72Pro polymorphisms.
  • (ii) that there was a significant increase in the Arg/Pro heterozygous genotype among high-grade astrocytomas compared with non-astrocytomas (P = 0.002); and (iii) that there was a significant increase in the Arg/Pro heterozygous genotype among high-grade astrocytomas containing transdominant as well as recessive p53 mutations compared with controls (P = 0.002).
  • Our results suggest a possible association between P53 Arg72Pro polymorphisms and susceptibility to brain tumors, particularly high-grade astrocytomas.

  • BACKGROUND: High-grade astrocytomas are rare in young children, but have been reported to have a better prognosis than similar tumors in older patients.
  • PROCEDURE: We retrospectively reviewed the clinical characteristics, survival, and long-term sequelae for patients younger than 3 years old with high-grade astrocytoma, treated at a single institution between 1984 and 2005.
  • Histology included anaplastic astrocytoma (n = 9), glioblastoma multiforme (n = 5), and malignant glioma (n = 2).
  • Six patients received scheduled irradiation and six were irradiated at the time of disease progression.
  • CONCLUSIONS: Young children with high-grade astrocytoma have better long-term overall survival than older patients, but recurrence is common, and most children require irradiation.

  • [Title] Epidermal growth factor receptor and proliferating cell nuclear antigen in astrocytomas.
  • AIMS: The involvement of various growth factors, growth factor receptors and proliferative markers in the molecular pathogenesis of astrocytic neoplasms are being studied extensively.
  • Since EGFR and proliferating cell nuclear antigen (PCNA) are involved in mitogenic signal transduction and cellular proliferation pathway, we have studied the correlation between the expression of EGFR and PCNA labeling index in astrocytic tumors.
  • MATERIALS AND METHODS: We investigated the immunohistochemical expression of EGFR and PCNA using the appropriate monoclonal antibodies in 40 cases of astrocytic tumors of which 21 cases were glioblastoma, eight cases were Grade III or anaplastic astrocytomas and six cases were Grade II or diffuse astrocytomas and five cases were Grade I or pilocytic astrocytomas.
  • RESULTS: Both the EGFR expression and PCNA labeling index increase with increasing grades of astrocytomas with a significantly high percentage of cells showing positive staining for both EGFR and PCNA in GBM and Grade III astrocytomas compared to Grade II astrocytomas.
  • The expression levels of both EGFR and PCNA were low in Grade I or pilocytic astrocytomas.
  • CONCLUSIONS: A significant correlation was found between EGFR overexpression and PCNA labeling index in Grade III and Grade II astrocytomas and glioblastoma.
  • These suggest that the tumor proliferation, at least in higher grades of astrocytomas is dependent in some measure on EGF and EGFR-related signaling pathways.

  • [Title] Cerebrospinal fluid cytologic findings of a pleomorphic xanthoastrocytoma: a case report.
  • BACKGROUND: Pleomorphic xanthoastrocytoma (PXA) is a rare astrocytic neoplasm with a relatively favorable prognosis.
  • Characteristic histologic features include pleomorphic tumor cells and lipidized cells expressing glial fibrillary acidic protein (GFAP), corresponding to a World Health Organization grade 2 tumor.
  • Computed tomography of the central nervous system revealed a supracallous periventricular tumor mass suggestive of either a lymphoma or a metastatic carcinoma.
  • CSF revealed 18 cells/mm3 and contained numerous tumor cells highly pleomorphic in size and shape.
  • A primitive glial proliferation was found, and paraffin-embedded tumor tissue obtained by biopsy confirmed the diagnosis of anaplastic PXA.

  • [Title] Nitrosourea efficacy in high-grade glioma: a survival gain analysis summarizing 504 cohorts with 24193 patients.
  • Even though past studies have suggested efficacy of nitrosourea drugs in patients with high-grade glioma and temozolomide has recently been shown significantly to be beneficial, no conclusive comparisons between these agents have been published.
  • We performed a survival gain analysis of 364 studies describing 24,193 patients with high-grade glioma treated in 504 cohorts, and compared the effects of drugs.
  • The most frequent diagnoses were glioblastoma multiforme (GBM) (72%) and anaplastic astrocytoma (22%).
  • This information allowed the calculation of a predicted mOS for each cohort based on their prognostic factors independent of treatment.

  • We describe the cases of 2 patients with a congenital malignant glioma that responded to chemotherapy.
  • A T(1)-weighted gadolinium-enhanced magnetic resonance image showed a large tumor in his right frontal lobe.
  • The tumor was partially resected, and the histological diagnosis was malignant ganglioglioma.
  • The child then underwent 6 cycles of chemotherapy (mainly carboplatin and etoposide), and the residual tumor shrank.
  • The tumor was then partially resected during a second operation, after which the patient underwent 5 cycles of chemotherapy (a combination of carboplatin, etoposide, vincristine, ifosfamide, cisplatin and cyclophosphamide).
  • The tumor has not recurred in more than 8.5 years.
  • The T(1)-weighted gadolinium-enhanced magnetic resonance image showed a large suprasellar tumor.
  • The tumor was partially resected, and the histological diagnosis was anaplastic astrocytoma.
  • The patient underwent 8 cycles of chemotherapy (MCNU, carboplatin and etoposide) and the tumor has not recurred in more than 7.5 years.
  • Our experience indicates that, if surgical removal and chemotherapy are done aggressively for malignant gliomas in neonates and infants, long-term survival is possible.

  • [Title] Progress in clinical neurosciences: Advances in the management of low-grade gliomas.
  • The management of low-grade gliomas represents one of the most challenging and controversial areas in neuro-oncology.
  • Many aspects of the treatment of low-grade gliomas are debated, including the optimal timing of surgery and radiotherapy, the benefit of extensive surgery, and the impact of these variables on the natural history of these indolent and generally incurable tumours.
  • The recognition that as many as two thirds of low-grade gliomas have oligodendroglial features, advances in molecular diagnostics making accurate pathologic diagnosis of oligodendroglial tumours possible, and the established chemosensitivity of malignant oligodendrogliomas, have raised new issues surrounding the potential value of chemotherapy for low-grade gliomas.
  • This review will be restricted to low-grade diffuse astrocytomas, oligodendrogliomas, and low-grade mixed oligoastrocytomas in adults, and provide evidence-based guidelines for the management of these tumours, including the emerging role of chemotherapy as initial treatment.

  • [Title] Spinal glioneuronal tumor with neuropil-like islands and meningeal dissemination: histopathological and radiological study of a pediatric case.
  • In the present report we describe a case of a 15-month-old child with a spinal GTNI of the cervical region and meningeal dissemination.
  • Histologically the tumor was composed of round, small neurocytic-like cells arranged around eosinophilic neuropil cores and embedded in a diffuse fibrillar glial component forming prominent "rosetted" neuropil islands displaying strong immunoreactivity for neuronal markers.
  • Cerebral GTNI shows abundant glial components not rarely exhibiting anaplastic features that justify their inclusion within the group of diffuse astrocytomas.

  • Procarbazine alone, or more commonly combined in the PCV (procarbazine, lomustine [CCNU], and vincristine) regimen, is also effective in treating gliomas comprising astrocytomas, glioblastomas, and oligodendrogliomas.
  • In conclusion, the use of procarbazine in combination with other drugs means that it remains a major anticancer drug in the management of Hodgkin's lymphoma and gliomas.

  • In primary cultured rat brain astrocytes and C6 astroglioma cells, both cRA and tRA decreased IFN-gamma-induced expression of interferon regulatory factor-1.
  • Furthermore, the effect of pre-treated RA was abolished in the presence of cycloheximide, indicating a requirement for de novo protein synthesis.

  • To identify targets critical to malignant childhood astrocytoma, we compared the expression of receptor tyrosine kinase- associated genes between low-grade and high-grade pediatric astrocytomas.
  • The highest differentially overexpressed gene in high-grade astrocytoma is insulin-like growth factor- binding protein-2 (P = .0006).
  • Insulin-like growth factor- binding protein-2 stimulation had no effect on astrocytoma cell growth and migration, and minimally inhibited insulin-like growth factor-1-mediated migration, but not insulin-like growth factor-2-mediated migration.
  • DNA-PKcs is also highly overexpressed by high-grade astrocytomas.
  • These findings suggest insulin-like growth factor-binding protein-2 plays a role in astrocytoma progression by promoting DNA-damage repair and therapeutic resistance.

  • [Title] l-Glutamate in Middlebrook 7H9 culture medium upregulates matrix metalloproteinase-2 secretion from human astrocytoma cells.
  • Whilst investigating the secretion of MMP-2 from human U373-MG astrocytoma cells, we observed elevated MMP-2 secretion in response to Middlebrook 7H9 media but not to Mycobacterium tuberculosis itself.
  • Middlebrook 7H9 media did not stimulate MMP-1 or MMP-9 secretion from astrocytoma cells.
  • The excitatory neurotransmitter l-glutamate, at concentrations found in Middlebrook 7H9 media, induced significant astrocytoma MMP-2 secretion (p<0.05).
  • l-Glutamate-induced MMP-2 activity may contribute to neuropathology in various CNS diseases and may generate misleading data in pathogen studies where Middlebrook 7H9 is the culture medium.

  • [Title] In vitro study of astrocytic tumour metabolism by proton magnetic resonance spectroscopy.
  • In vivo magnetic resonance spectroscopy (MRS) studies of glial brain tumours reported that higher grade of astrocytoma is associated with increased level of choline-containing compounds (Cho) and decreased levels of N-acetylaspartate (NAA) and creatine and phosphocreatine (Cr).
  • In this work, we studied the metabolism of glioma tumours by in vitro proton magnetic resonance spectroscopy (1H-MRS).
  • 1H-MR spectra were recorded in vitro from perchloric acid extracts of astrocytoma (WHO II) and glioblastoma multiforme (WHO IV) samples.
  • We observed differences between astrocytoma and glioblastoma multiforme in the levels of Cho, alanine, lactate, NAA, and glutamate/glutamine.
  • In astrocytoma samples, we found higher MR signal of NAA and lower signal of Cho and alanine.
  • The NAA/Cr ratio was higher in astrocytomas than in glioblastomas multiforme.

  • OBJECT: Because activation of Notch receptors has been suggested to be critical for Ras-mediated transformation, and because many gliomas exhibit deregulated Ras signaling, the authors measured Notch levels and activation in primary samples and cell lines derived from glioblastoma multiforme (GBM) as well as the contribution of Notch pathway activation to astrocytic transformation and growth.
  • CONCLUSIONS: Notch activation contributes to Ras-induced transformation of glial cells and to glioma growth, survival, or both and as such may represent a new target for GBM therapy.

  • Malignant gliomas are the most common primary brain tumor in adults, but the prognosis for patients with these tumors remains poor despite advances in diagnosis and standard therapies such as surgery, radiation therapy, and chemotherapy.
  • Progress in the treatment of gliomas now depends to a great extent on an increased understanding of the biology of these tumors.
  • Recent insights into the biology of gliomas include the finding that tyrosine kinase receptors and signal transduction pathways play a role in tumor initiation and maintenance.
  • Deregulation of phosphatidylinositol 3-kinase (PI3K) signaling pathways resulting from genetic alterations in the PTEN tumor suppressor gene on 10q23 at the level of LOH, mutation and methylation have been identified in at least 60% of glioblastoma.
  • Loss of PTEN function by mutation or LOH correlates with poor survival in anaplastic astrocytoma and glioblastoma, suggesting that PTEN plays a role in patient outcome.
  • Interestingly, amplification of Epidermal growth factor receptor (EGFR) in the background of heterozygous PTEN knockout mice develop invasive glioma very similar to human glioblastoma, demonstrating the importance of PTEN in glioma progression and providing a model system to evaluate the efficacy of targeting PTEN in glioblastoma.

  • [Title] Glioblastoma with adipocyte-like tumor cell differentiation--histological and molecular features of a rare differentiation pattern.
  • We report on three adult patients with primary glioblastomas showing prominent adipocytic (lipomatous) differentiation, hence referred to as "glioblastomas with adipocyte-like tumor cell differentiation."
  • Histologically, the tumors demonstrated typical features of glioblastoma but additionally contained areas consisting of glial fibrillary acidic protein (GFAP)-positive astrocytic tumor cells resembling adipocytes, that is, containing large intracellular lipid vacuoles.
  • The second tumor showed gains of chromosomes 3, 4, 8q and 12 as well as losses of chromosomes 10, 13, 15q, 19 and 22.
  • In addition, this tumor carried homozygous deletions of CDKN2A and p14(ARF) as well as point mutations in the TP53 and PTEN genes.
  • The third tumor also had a mutation in the PTEN gene.
  • Taken together, our results define a rare glioblastoma differentiation pattern and indicate that glioblastomas with adipocyte-like tumor cell differentiation share common molecular genetic features with other primary glioblastomas.

  • [Title] Efficacy of temozolomide is correlated with 1p loss and methylation of the deoxyribonucleic acid repair gene MGMT in malignant gliomas.
  • Promoter methylation of the deoxyribonucleic acid (DNA) repair gene, O(6)-methylguanine-DNA methyltransferase (MGMT), is associated with improved outcome of patients with glioblastoma multiforme and anaplastic astrocytoma treated with temozolomide (TMZ).
  • Molecular genetic analysis of loss of heterozygosity (LOH) of 1p, 19q, or 10q, p53 mutation, and MGMT promoter methylation was performed in 44 assessable tumor specimens obtained from 46 patients with recurrent malignant gliomas, including 21 with glioblastoma multiforme, 17 with anaplastic astrocytoma, and eight with anaplastic oligoastrocytoma, which have heterogeneous features and variable histological diagnosis, to assess the correlation with the response to TMZ.
  • LOH of 1p in the heterogeneous population of malignant gliomas may be one of the important factors besides MGMT methylation that predict better outcome in patients treated with TMZ.

  • [Title] S100B Protein Regulates Astrocyte Shape and Migration via Interaction with Src Kinase: IMPLICATIONS FOR ASTROCYTE DEVELOPMENT, ACTIVATION, AND TUMOR GROWTH.
  • We show here that reducing S100B levels in the astrocytoma cell line GL15 and the Müller cell line MIO-M1 by small interference RNA technique results in a rapid disassembly of stress fibers, collapse of F-actin onto the plasma membrane and reduced migration, and acquisition of a stellate shape.
  • These results suggest that S100B might contribute to reduce the differentiation potential of cells of the astrocytic lineage and participate in the astrocyte activation process in the case of brain insult and in invasive properties of glioma cells.

  • [Title] Quantitative spectroscopic analysis of 5-aminolevulinic acid-induced protoporphyrin IX fluorescence intensity in diffusely infiltrating astrocytomas.
  • The fluorescence of protoporphyrin IX (PpIX) induced endogenously by 5-aminolevulinic acid (5-ALA) administration has recently been used for the intraoperative visualization of glioma tissues.
  • To increase the sensitivity of photodetection, the emission spectra of 5-ALA-induced PpIX fluorescence was quantitatively measured in tissues taken from six cases of en bloc resected diffusely infiltrating astrocytomas (2 diffuse astrocytomas, 2 anaplastic astrocytomas, and 2 glioblastomas), and the correlation assessed between the fluorescence intensity and histological features.
  • The ratio of the peak emission intensity to reflected excitation intensity or fluorescence intensity ratio was less than 0.001 for all 36 non-tumor tissues.
  • The MIB-1 proliferation index was the most powerful determinant, suggesting that higher cell proliferation may govern preferential PpIX accumulation in glioma cells.
  • This preliminary study suggests that spectroscopic analysis may be useful for optimizing the removal of diffuse gliomas.

  • [Title] [Application of apparent diffusion coefficient and fractional anisotropy in identification of tumor component and grading of brain astrocytoma].
  • OBJECTIVE: To evaluate the value of apparent diffusion coefficient (ADC) and fractional anisotropy (FA) in identification of tumor element and grading of brain astrocytoma.
  • METHODS: Thirty-three patients with histologically confirmed astrocytoma underwent diffusion weighted imaging (DWI), diffusion tensor imaging (DTI), and conventional MRI before operation.
  • The values of ADC and FA of different regions in the same tumor and of astrocytoma of different grades were measured and compared.
  • RESULTS: The ADC values of the tumor parenchyma, necrotic region, peritumoral edema region were (1.28 +/- 0.44), (1.97 +/- 0.53), and (1.74 +/- 0.47) respectively, all significantly higher than that of the corresponding normal brain tissues [(0.80 +/- 0.18), P = 0.009, P = 0.000, P = 0.000] with significantly differences between the tumor parenchyma and necrotic region and peritumoral edema region (both P < 0.05), however, there was not significant difference between the necrotic region and peritumoral edema region.
  • The FA values of the tumor parenchyma, necrotic region, and peritumoral edema region were (0.18 +/- 0.07), (0.14 +/- 0.05), and (0.16 +/- 0.05) respectively, all significantly higher than that of the corresponding normal brain tissues [(0.58 +/- 0.10), all P = 0.000], without significant differences among the former 3 groups.
  • There were no significant differences in the ADC and FA values among the tumors at different grades, however, there was a tendency of ADC to decrease and of FA to increase along the increase of grade of tumor, although not significantly.
  • CONCLUSION: ADC value plays an important part in distinguishing tumor components and determining tumor boundary, and plays a certain role in judging the grade of astrocytomas.
  • FA value is vital to determine the tumor boundary, and has certain value in differentiating high-grade from low-grade astrocytomas.

  • [Title] Up-regulation of NG2 proteoglycan and interferon-induced transmembrane proteins 1 and 3 in mouse astrocytoma: a membrane proteomics approach.
  • Traditionally, cell surface membrane antigens have served as biomarkers that distinguish brain tumor origin and malignancy.
  • In this study, membrane proteins were identified from a terminally differentiated mouse astrocyte (AC) and CT-2A astrocytoma (CT-2A) cell line using liquid-chromatography coupled with tandem mass spectrometry (LC-MS/MS).
  • Therefore, our data suggest that the CT-2A tumor may be derived from NG2 glia rather than from fully differentiated astrocytes.
  • Moreover, the CT-2A cells also express a series of interferon-induced signature proteins that may be specific to this tumor.
  • These data highlight the utility of LC-MS/MS for the identification of brain tumor membrane biomarkers.

  • Here we show that HIV-1 Nef has an effect on the transcriptional levels of a cellular protein, anaplastic lymphoma kinase (ALK), that is preferentially expressed in the central and peripheral nervous system at late embryonic stages.
  • By its overexpression along with Nef, the authors demonstrate ALK ability to influence, at least in the U87MG astrocytic glioma cells, the mytogen-activated protein kinase (MAP-K)-dependent pathway.
  • Moreover, although in the absence of a physical direct interaction, Nef and ALK activate matrix metalloproteinases (MMPs), which are likely to contribute to blood-brain barrier (BBB) damage in HAD.

  • [Title] A mosaic mouse model of astrocytoma identifies alphavbeta8 integrin as a negative regulator of tumor angiogenesis.
  • Furthermore, little is known about how cancer cells selectively circumvent the actions of these inhibitors to promote pathological angiogenesis, a requisite event for tumor progression.
  • Using mosaic mouse models of the malignant brain cancer, astrocytoma, we report that tumor cells induce pathological angiogenesis by suppressing expression of the ECM protein receptor alphavbeta8 integrin.
  • Diminished integrin expression in astrocytoma cells leads to reduced activation of latent TGFbetas, resulting in impaired TGFbeta receptor signaling in tumor-associated endothelial cells.
  • These data reveal that astrocytoma cells manipulate their angiogenic balance by selectively suppressing alphavbeta8 integrin expression and function.

  • [Title] ABCC drug efflux pumps and organic anion uptake transporters in human gliomas and the blood-tumor barrier.
  • We therefore analyzed the expression and localization of six members of the multidrug resistance protein family of ATP-dependent efflux pumps (ABCC1-ABCC6, formerly MRP1-MRP6) and of six organic anion uptake transporters (OATP1A2, OATP1B1, OATP1B3, OATP1C1, OATP2B1, and OATP4A1) in 61 human glioma specimens of different histologic subtypes.
  • At the protein level, however, only OATP1A2 and OATP2B1 were detectable by immunofluorescence microscopy in the luminal membrane of endothelial cells forming the blood-brain barrier and the blood-tumor barrier, but not in the glioma cells.
  • ABCC4 and ABCC5 proteins were the major ABCC subfamily members in gliomas, localized both at the luminal side of the endothelial cells and in the glioma cells of astrocytic tumors and in the astrocytic portions of oligoastrocytomas.
  • These results indicate that expression of ABCC4 and ABCC5 is associated with an astrocytic phenotype, in accordance with their expression in astrocytes and with the higher chemoresistance of astrocytic tumors as compared with oligodendrogliomas.
  • Our data provide a basis for the assessment of the role of uptake transporters and efflux pumps in the accessibility of human gliomas for chemotherapeutic agents.

  • [Title] A phase 1-2, prospective, double blind, randomized study of the safety and efficacy of Sulfasalazine for the treatment of progressing malignant gliomas: study protocol of [ISRCTN45828668].
  • BACKGROUND: The prognosis of patients suffering from WHO grade 3 and 4 astrocytic glioma remains poor despite surgery, radiation therapy and the use of current chemotherapy regimen.
  • Indeed, the median survival of glioblastoma multiforme (WHO grade 4) patients is at best 14.6 month with only 26.5 percent of the patients still alive after 2 years and the median survival of anaplastic astrocytomas (WHO grade 3) is 19.2 month.
  • Recent evidence suggests that the transcription factor NF-kappaB is constitutively expressed in malignant gliomas and that its inhibition by drugs like Sulfasalazine may block the growth of astrocytic tumors in vitro and in experimental models of malignant gliomas.
  • A total of twenty patients with progressive malignant glioma despite surgery, radiation therapy and a first line of chemotherapy will be recruited and assigned to four dosage regimen of Sulfasalazine.
  • Primary endpoints are drug safety in the setting of malignant gliomas and tumor response as measured according to MacDonald's criteria.
  • DISCUSSION: The aim of this study is to evaluate the safety and efficacy of Sulfasalazine as a treatment for recurring malignant gliomas.

  • [Title] Treatments for astrocytic tumors in children: current and emerging strategies.
  • Despite these accomplishments, CNS tumors remain the leading cause of death in pediatric oncology.
  • Astrocytic tumors form the most common histologic group among childhood brain tumors.
  • They are a heterogeneous group that from a practical therapeutic point of view can be subdivided into low-grade astrocytomas (LGA), optic pathway gliomas (OPG), high-grade astrocytomas (HGA), and brainstem gliomas (BSG).
  • Careful follow-up without any treatment is indicated for a small percentage of patients diagnosed with LGA with an indolent course including children with neurofibromatosis type 1 (NF1).
  • Radiation therapy is generally recommended for children with progressive LGA, or after failure of chemotherapy, accomplishing tumor control at 10 years in over 60% of patients.
  • OPG is the most common type of brain tumor associated with NF1.
  • Tumor growth in some of these patients is slow with no treatment recommended for an extended period of time.
  • The prognosis for children with the remaining types of astrocytomas remains poor.
  • Careful evaluation of histology, location of the tumor, patient age, and consideration of treatment-related morbidity play an important part in selecting between clinical observation, surgery, radiation, chemotherapy, or investigational agents.
  • The goals of treatment for astrocytic tumors should extend well beyond objective responses and increased survival.

  • The prognoses for these tumors are related to several factors, such as the age of the patient and the location and histology of the tumor.
  • Arising from glial cells, gliomas represent over 36% of all primary CNS tumors and consist of astrocytomas, oligodendrogliomas, ependymomas, mixed gliomas, and neuroepithelial tumors.
  • The most common gliomas are astrocytomas, and these tumors are typically classified by the World Health Organization (WHO) as Grades I through IV.
  • Grade IV, the most malignant grade of astrocytoma, includes glioblastoma multiforme (GBM), the most common malignant primary CNS glioma in adults, which represents 51% of all CNS gliomas.
  • Here we describe the molecular and cellular events associated with malignant glioma initiation and progression.
  • We also review the importance of glioma stem cell biology and tumor immunology in early gliomagenesis.
  • In addition, we present a brief description of the most common malignant primary CNS glioma in pediatric patients - medulloblastoma, as well as familial cancer syndromes that include gliomas as part of the syndrome.

  • [Title] Activation of the Hedgehog pathway in pilocytic astrocytomas.
  • Pilocytic astrocytoma is commonly viewed as a benign lesion.
  • However, disease onset is most prevalent in the first two decades of life, and children are often left with residual or recurrent disease and significant morbidity.
  • The Hedgehog (Hh) pathway regulates the growth of higher WHO grade gliomas, and in this study, we have evaluated the activation and operational status of this regulatory pathway in pilocytic astrocytomas.
  • Expression levels of the Hh pathway transcriptional target PTCH were elevated in 45% of tumor specimens analyzed (ages 1-22 years) and correlated inversely with patient age.
  • Evaluation of a tissue array revealed oligodendroglioma-like features, pilomyxoid features, infiltration, and necrosis more commonly in specimens from younger patients (below the median patient age of 10 years).
  • Taken together, these findings suggest that Hh pathway activation is common in pediatric pilocytic astrocytomas and may be associated with younger age at diagnosis and tumor growth.

  • [Title] The role of microglia/macrophage system in the tissue response to I-125 interstitial brachytherapy of cerebral gliomas.
  • OBJECTIVE: To study histopathologic changes and the role of the microglia/macrophage cell in the therapeutic effect of I-125 interstitial brachytherapy on the cerebral gliomas.
  • METHODS: Out of a series of 60 cases with cerebral astrocytomas and other brain tumors treated with I-125 interstitial brachytherapy, autopsy materials were available in ten cases 0.75 and 60 months after irradiation.
  • The patients were treated with the maximum dosage (60 Gy) on the tumor periphery.
  • Besides the routine hematoxylin-eosine and Mallory's PTAH trichrome staining, immunohistochemical reactions were carried out for CD15, CD31, CD34, CD45, CD68, CPM, HAM56 and HLR-DR antigens on paraffin sections to study immunologic phenotypic characteristics of the reaction cell population around gliomas after I-125 treatment.
  • The reactive zone was characterized by astrocytic gliosis but vascular proliferation and macrophages were lacking.
  • The established phase of reactive zone around the necrotic center is characterized by a narrow inner rim of microglial accumulation and a broad outer area characterized by astrocytic gliosis, vascular proliferation, activated microglia and infiltration by macrophages.
  • In the burned-out phases of I-125 interstitial brachytherapy of gliomas, the necrosis undergoes liquefaction and the microglial rim is replaced by astrocytic gliosis which can be considered as equivalent to the scar tissue formed around necrosis outside the central nervous system.

  • To investigate the functional significance of alphaB-crystallin induction in astrocytes, we generated a stable C6 astroglioma cell line overexpressing alphaB-crystallin.
  • Furthermore, the repression of alphaB-crystallin expression by alphaB-crystallin siRNA transfection suppressed this protective effect, indicating that alphaB-crystallin is responsible for the protection against H2O2-induced apoptosis in C6 astroglioma cells.

  • Gliomas are the most frequent primary central nervous system tumors and the molecular mechanisms that underlie the development and progression of these tumors are far from being completely understood.
  • The purpose of this study was to clarify the incidence of B-RAF mutations and their possible relation with tumor progression in a series of 82 human gliomas, including 49 astrocytic and 33 oligodendroglial tumors.
  • These data suggest that activating mutations of B-RAF are not a frequent event in gliomas; nevertheless, when present they are associated with high-grade malignant lesions.

  • [Title] Genomic and expression profiling of glioblastoma stem cell-like spheroid cultures identifies novel tumor-relevant genes associated with survival.
  • PURPOSE: Glioblastoma spheroid cultures are enriched in tumor stem-like cells and therefore may be more representative of the respective primary tumors than conventional monolayer cultures.
  • We exploited the glioma spheroid culture model to find novel tumor-relevant genes.
  • Microarray-based gene expression analysis was applied to determine genes with differential expression compared with normal brain tissue and to nonneoplastic brain spheroids in glioma spheroid cultures.
  • Immunohistochemistry on tissue microarrays revealed that expression of AJAP1, EMP3, and PDPN was significantly associated with overall survival of astrocytic glioma patients.
  • CONCLUSION: We identified a set of novel candidate genes that likely play a role in glioblastoma pathogenesis and implicate AJAP1, EMP3, and PDPN as molecular markers associated with the clinical outcome of glioma patients.

  • Glioma, and in particular high-grade astrocytoma termed glioblastoma multiforme (GBM), is the most common primary tumor of the brain.
  • Modeling of astrocytomas by genetic manipulation of mice suggests that deregulation of the pathways that control gliogenesis during normal brain development, such as the differentiation of neural stem cells (NSCs) into astrocytes, might contribute to GBM formation.
  • Use of novel techniques including large-scale genomics and proteomics in combination with relevant mouse models will most likely provide novel insights into the molecular mechanisms underlying glioma formation and will hopefully lead to development of treatment modalities for GBM.

  • [Title] mTOR promotes survival and astrocytic characteristics induced by Pten/AKT signaling in glioblastoma.
  • Combined activation of Ras and AKT leads to the formation of astrocytic glioblastoma multiforme (GBM) in mice.
  • We demonstrate here that loss of Pten is similar to AKT activation in the context of glioma formation in mice.
  • Blockade of mTOR results in regional apoptosis in these tumors and conversion in the character of surviving tumor cells from astrocytoma to oligodendroglioma.
  • These data suggest that mTOR activity is required for the survival of some cells within these GBMs, and mTOR appears required for the maintenance of astrocytic character in the surviving cells.
  • Furthermore, our study provides the first example of conversion between two distinct tumor types usually thought of as belonging to specific lineages, and provides evidence for signal transduction-mediated transdifferentiation between glioma subtypes.

  • [Title] The in vitro effects of tricyclic drugs and dexamethasone on cellular respiration of malignant glioma.
  • BACKGROUND: In this investigation the effects of tricyclic drugs on cellular respiration were studied using the anaplastic astrocytoma cell line IPSB-18 by use of a Clark-type oxygen electrode which measured changes in cellular respiration rate (oxygen consumption), in a dose-response assay.
  • Overall, it appeared that clomipramine and its metabolite norclomipramine were the most potent inhibitors of cellular respiration in glioma cells over the concentration range 0.5-0.9 mM.
  • Dexamethasone was able to induce inhibition of cellular respiration both alone in glioma cells, and in combination with clomipramine, where it had an additive or synergistic effect, thereby increasing cell death.
  • CONCLUSION: The extensive research currently ongoing and previously reported regarding the use of clomipramine as a potential antineoplastic agent aimed at targeting the mitochondria of gliomas is promising.

  • A 3-year-old boy was referred for management of a 9 month history of acute acquired comitant esotropia.
  • The mass was completely excised and histological examination confirmed the diagnosis of pilocytic astrocytoma.
  • Therefore, acute onset comitant esotropia in a child can be the first sign of a cerebellar tumor, even without any other neurological signs and symptoms.

  • In the present study, we examined the expression of the EphB6 variant (EphB6v) in a panel of brain tumor cell lines and glioblastoma tissues and we found that EphB6v was preferentially expressed in malignant brain tumors, such as glioblastomas and anaplastic astrocytomas.
  • The two EphB6v-derived peptides exhibited the ability to bind to human leukocyte antigen (HLA)-A0201 molecules, and each of them was able to induce cytotoxic T lymphocytes in vitro in the peripheral blood mononuclear cells of HLA-A2(+) glioma patients.

  • Histologic studies showed low-grade astrocytoma (WHO grade I or II) in 16 cases, anaplastic astrocytoma in 1, and oligoastrocytoma (WHO grade III) in 1.
  • Treatment included partial tumor resection in 12 patients, chemotherapy in 5, and radiotherapy in 3.
  • All treatment modalities led to tumor shrinkage and stabilization for a variable period, but none of them totally eradicated the tumor.
  • Fourteen (78%) of 18 patients had a sustained reduction of tumor size between 6 months and 17 years.
  • Two patients died, none with neurofibromatosis-1, with a hypothalamic/chiasmatic tumor with suprasellar extension and accompanying electrolyte abnormalities.
  • Because progression of these tumors is slow and associated with endocrinopathy, we recommend chemotherapy as a primary treatment of OPHG if the disease progresses.

  • [Title] Epigenetic silencing of the protocadherin family member PCDH-gamma-A11 in astrocytomas.
  • In a microarray-based methylation analysis of astrocytomas [World Health Organization (WHO) grade II], we identified a CpG island within the first exon of the protocadherin-gamma subfamily A11 (PCDH-gamma-A11) gene that showed hypermethylation compared to normal brain tissue.
  • Bisulfite sequencing and combined bisulfite restriction analysis (COBRA) was performed to screen low- and high-grade astrocytomas for the methylation status of this CpG island.
  • Hypermethylation was detected in 30 of 34 (88%) astrocytomas (WHO grades II and III), 20 of 23 (87%) glioblastomas (WHO grade IV), and 8 of 8 (100%) glioma cell lines.
  • There was a highly significant correlation (P = .00028) between PCDH-gamma-A11 hypermethylation and decreased transcription as determined by competitive reverse transcription polymerase chain reaction in WHO grades II and III astrocytomas.
  • After treatment of glioma cell lines with a demethylating agent, transcription of PCDH-gamma-A11 was restored.
  • In summary, we have identified PCDH-gamma-A11 as a new target silenced epigenetically in astrocytic gliomas.
  • The inactivation of this cell-cell contact molecule might be involved in the invasive growth of astrocytoma cells into normal brain parenchyma.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • BACKGROUND: Conventional magnetic resonance (MR) imaging has a number of limitations in the diagnosis of the most common intracranial brain tumors, including tumor specification and the detection of tumoral infiltration in regions of peritumoral edema.
  • PURPOSE: To prospectively assess if diffusion-weighted MR imaging (DWI) could be used to differentiate between different types of brain tumors and to distinguish between peritumoral infiltration in high-grade gliomas, lymphomas, and pure vasogenic edema in metastases and meningiomas.
  • MATERIAL AND METHODS: MR imaging and DWI was performed on 93 patients with newly diagnosed brain tumors: 59 patients had histologically verified high-grade gliomas (37 glioblastomas multiforme, 22 anaplastic astrocytomas), 23 patients had metastatic brain tumors, five patients had primary cerebral lymphomas, and six patients had meningiomas.
  • Apparent diffusion coefficient (ADC) values of tumor (enhancing regions or the solid portion of tumor) and peritumoral edema, and ADC ratios (ADC of tumor or peritumoral edema to ADC of contralateral white matter, ADC of tumor to ADC of peritumoral edema) were compared with the histologic diagnosis.
  • ADC values and ratios of high-grade gliomas, primary cerebral lymphomas, metastases, and meningiomas were compared by using ANOVA and multiple comparisons.
  • Optimal thresholds of ADC values and ADC ratios for distinguishing high-grade gliomas from metastases were determined by receiver operating characteristic (ROC) curve analysis.
  • RESULTS: Statistically significant differences were found for minimum and mean of ADC tumor and ADC tumor ratio values between metastases and high-grade gliomas when including only one factor at a time.
  • Including a combination of in total four parameters (mean ADC tumor, and minimum, maximum and mean ADC tumor ratio) resulted in sensitivity, specificity, positive (PPV), and negative predictive values (NPV) of 72.9, 82.6, 91.5, and 54.3% respectively.
  • CONCLUSION: Our results suggest that ADC values and ADC ratios (minimum and mean of ADC tumor and ADC tumor ratio) may be helpful in the differentiation of metastases from high-grade gliomas.
  • It cannot distinguish high-grade gliomas from lymphomas, and lymphomas from metastases.
  • ADC values and ADC ratios in peritumoral edema cannot be used to differentiate edema with infiltration of tumor cells from vasogenic edema when measurements for high-grade gliomas, lymphomas, metastases, and meningiomas were compared.

  • [Title] Isoform-specific expression of 14-3-3 proteins in human astrocytoma.
  • In the present study, the levels of all seven 14-3-3 isoforms were examined in astrocytoma.
  • METHODS: The expression of 14-3-3 isoforms and their protein expression levels were examined in five glioma cell lines by western blotting.
  • Then in astrocytoma tissues, we investigated expression percentages of each isoform by immunohistochemistry.
  • RESULTS: 14-3-3beta and eta were specifically expressed in astrocytoma, and their expression frequencies and levels increased with the increase of astrocytoma malignancy.
  • The result from glioma cell lines was consistent with that from astrocytoma tissue.
  • CONCLUSIONS: In our study, we found two tumor-specific isoforms of 14-3-3 in astrocytoma.
  • They might be involved in astrocytoma tumorigenesis and may be useful as targets for therapy.

  • We report a patient with infantile Alexander disease (AXD) due to the recurrent p.Arg79Cys GFAP mutation.
  • In addition to typical AXD abnormalities, magnetic resonance imaging demonstrated a tumor-like lesion of the optic chiasm suggestive of a glioma.
  • Rare radiological and pathological tumor-like lesions have already been reported in AXD patients.
  • This patient confirms that enlargement of the optic chiasm is a rare feature of AXD, possibly linked to abnormal astrocytic proliferation.

  • [Title] Histomorphometry of tumour cell nuclei in astrocytomas using shape analysis, densitometry and topometric analysis.
  • Although tumour cell nuclei are important histological structures for grading of astrocytomas according to the WHO-classification of brain tumours, there is no reported morphometric study of astrocytomas which describes quantitatively the four main morphologic criteria of tumour cell nuclei: size, shape, texture (densitometric characteristics) and spatial relationships between the nuclei (topometric analysis).
  • Using a set of morphometric parameters describing these criteria as well as the Ki67-proliferation index, 74 astrocytomas from 74 patients were studied by means of a digital image analysis system.
  • The objective of the study was to test, if these morphometric parameters were sufficient for statistical discrimination between pilocytic astrocytomas WHO-grade I, astrocytomas grade II and anaplastic astrocytomas grade III.
  • In conclusion, the present morphometric procedure provided good discrimination between the tumour grades, supporting the view that histomorphometry of tumour cell nuclei could be a valuable tool for grading of astrocytomas.

  • [Title] WHO grade-specific comparative genomic hybridization pattern of astrocytoma - a meta-analysis.
  • To detect novel genetic alterations, many astrocytomas have been investigated by comparative genomic hybridization (CGH).
  • To identify aberration profiles characteristic of World Health Organization (WHO) grade I, II, III, and IV astrocytoma, we performed a meta-analysis of detailed genome wide CGH data of all 467 cases published so far.
  • Low-grade astrocytoma has already demonstrated one characteristic of glioblastoma multiforme, gain of chromosome 7 with a hot spot at 7q32, but without loss of chromosome 10.
  • In anaplastic astrocytoma, a more complex aberration pattern emerges from diffuse genetic imbalances.
  • In contrast to lower tumor grades, glioblastoma multiforme demonstrates +7p12 as the most frequently affected band on chromosome 7.
  • To quantify the gradual transition from WHO grade II-IV astrocytoma, we calculated the relative increase and decrease in frequency for each detected aberration of the tumor genome.
  • The most pronounced and diverse changes of genetic material occur at the virtual transition from low-grade to anaplastic astrocytoma.
  • Summing up, the expansion of the CGH results to the 850 GTG-band resolution enabled a meta-analysis to visualize WHO grade-specific aberration profiles in astrocytoma.

  • [Title] Serum IgE, tumor epidermal growth factor receptor expression, and inherited polymorphisms associated with glioma survival.
  • In population-based glioma patients, we examined survival in relation to potentially pertinent constitutive polymorphisms, serologic factors, and tumor genetic and protein alterations in epidermal growth factor receptor (EGFR), MDM2, and TP53.
  • We obtained 595 of 697 astrocytic tumors for marker studies.
  • Using a stringent P < 0.001, glioma survival was associated with ERCC1 C8092A [hazard ratio (HR), 0.72; 95% confidence limits (95% CL), 0.60-0.86; P = 0.0004] and GSTT1 deletion (HR, 1.64; 95% CL, 1.25-2.16; P = 0.0004); glioblastoma patients with elevated IgE had 9 months longer survival than those with normal or borderline IgE levels (HR, 0.62; 95% CL, 0.47-0.82; P = 0.0007), and EGFR expression in anaplastic astrocytoma was associated with nearly 3-fold poorer survival (HR, 2.97; 95% CL, 1.70-5.19; P = 0.0001).
  • We also suggest that tumor EGFR expression be incorporated into clinical evaluation of anaplastic astrocytoma patients.

  • [Title] Expression of targeting protein for Xenopus kinesin-like protein 2 is associated with progression of human malignant astrocytoma.
  • However, the contribution of TPX2 expression to astrocytoma progression is unclear.
  • The aim of this study was to investigate TPX2 expression in human astrocytoma samples and cell lines.
  • TPX2 protein expression was detected in the nucleus of astrocytoma tissues by immunohistochemistry and immunofluorescence staining.
  • Real-time PCR and Western blot analysis showed that the expression levels of TPX2 were higher in high-grade astrocytoma tissues and cell lines than that in low-grade astrocytoma tissues and normal cell lines.
  • Immunohistochemical analysis of tumor tissues from 52 patients with astrocytoma showed that TPX2 over-expression was significantly associated with decreased patient survival.
  • These data suggest that TPX2 expression is associated with the progression of malignant astrocytoma.

  • MATERIALS AND METHODS: We examined 65 patients with histologically or clinically diagnosed brain tumors (12 low-grade gliomas, 31 high-grade gliomas, 14 metastatic tumors, and 8 lymphomas) using a 1.5 T MR unit.
  • RESULTS: The ADC(min) values of low-grade gliomas (1.09+/-0.20 x 10(-3)mm(2)/s) were significantly higher (p<.001) than those of other tumors.
  • There were no statistical significant differences between glioblastomas (0.70+/-0.16 mm(2)/s), anaplastic astrocytomas (0.77+/-0.21 mm(2)/s), metastases (0.78+/-0.21 mm(2)/s), and lymphomas.
  • But, lymphomas had lower mean ADC(min) values (0.54+/-0.10mm(2)/s) than high-grade gliomas and metastases.
  • CONCLUSION: The ADC measurements may help to differentiate low-grade gliomas from high-grade gliomas, metastases, and lymphomas.

  • [Title] Magnetic resonance imaging and spectroscopy of pilomyxoid astrocytomas: case reports and comparison with pilocytic astrocytomas.
  • BACKGROUND AND PURPOSE: Pilomyxoid astrocytomas (PMAs) have been described only recently.
  • They appear as low-grade tumors sharing imaging features similar to pilocytic astrocytomas (PAs).
  • However, pilomyxoid astrocytomas have different histological features and behave more aggressively than PAs.

  • [Title] Phase I clinical trial of a TGF-beta antisense-modified tumor cell vaccine in patients with advanced glioma.
  • We performed a phase I clinical trial in grade IV astrocytoma to assess the safety of a whole-cell vaccine comprising autologous tumor cells genetically modified by a transforming growth factor-beta2 (TGF-beta2) antisense vector.
  • Blocking secretion of the immunosuppressive molecule TGF-beta in this manner should inhibit one of the major mechanisms by which tumor cells evade immune surveillance and should lead to clinically effective antitumor immunity.
  • Six patients with progressive WHO grade IV astrocytoma were enrolled in the trial.
  • Patients received 2-7 subcutaneous injections of 5 x 10(6)-2 x 10(7) autologous tumor cells per injection.
  • TGF-beta2 secretion by the tumor cells used to vaccinate patients was inhibited by 53-98%.
  • Two patients had partial regressions and two had stable disease following therapy.
  • Median survival of the responding patients was 78 weeks, compared to a historic value of 47 weeks for glioma patients treated conventionally.
  • These findings support further clinical evaluation of vaccines comprised of TGF-beta antisense-modified tumor cells.

  • [Title] Taurine: a potential marker of apoptosis in gliomas.
  • Magnetic resonance spectroscopy (MRS) can determine the tumour biochemical profile in vivo, and we have investigated whether a specific spectroscopic signature exists for apoptosis in human astrocytomas.
  • Metabolites, mobile lipids and macromolecules were quantified from presaturation HRMAS (1)H spectra acquired from 41 biopsies of grades II (n=8), III (n=3) and IV (n=30) astrocytomas.
  • We suggest that the taurine (1)H MRS signal in astrocytomas may be a robust apoptotic biomarker that is independent of tumour necrotic status.
