  • [Title] Expression of hypoxia-related tissue factors in astrocytic gliomas. A multivariate survival study with emphasis upon carbonic anhydrase IX.
  • It has been recently postulated that the hypoxia-inducible factor (HIF-1) pathway up-regulated by hypoxia accounts for CAIX overexpression in most human tumors.
  • In the present study, we examined the expression of this enzyme in diffuse gliomas of astrocytic origin in relation to vascular endothelial growth factor (VEGF) and HIF-1alpha expression, proliferation rate (as assessed with Ki-67 antigen), microvessel morphology, and survival.
  • Given the role of CAIX in the acidification of tumor environment and its up-regulation by hypoxia, it is thought that CAIX expression may be linked to resistance of tumor cells to radiotherapy by allowing them to acclimatize to a hypoxic and acidic microenvironment.

  • [Title] The expressions of carbonic anhydrase 9 and vascular endothelial growth factor in astrocytic tumors predict a poor prognosis.
  • Hypoxia in the tumor microenvironment triggers a variety of genetic and adoptive responses that regulate tumor growth.
  • Tumor hypoxia is often associated with a malignant phenotype, resistance to therapy, and poor survival.
  • The objectives of this study were to evaluate the expressions of carbonic anhydrase 9 (CA9) and vascular endothelial growth factor (VEGF) in astrocytic gliomas and to relate patterns of expression with prognosis, that is with histological grade and survival.
  • We investigated 78 World Health Organization (WHO) grade II, III, and IV astrocytic gliomas.
  • Fourteen tumors were grade II, 30 were grade III, and 34 were grade IV.
  • There were 3 CA9 positive tumors in grade II (21.4%), 10 in grade III (33.3%), and 27 in grade IV (79.4%).
  • For all tumors and WHO grade II, overall survival was found to be significantly dependent on CA9 expression (p=0.004, p=0.01).
  • Furthermore, VEGF expression was found to be significantly related to tumor grade (p=0.02) and tended to be related to overall survival (p=0.1).
  • Nevertheless, the expressions of CA9 and VEGF were found to be associated with tumor grade and possibly with survival.
  • Further studies on a larger patient population are needed to determine the correlation between the expressions of CA9, and VEGF in astrocytic gliomas and clinical outcome.

  • [Title] Grading astrocytic tumors by using apparent diffusion coefficient parameters: superiority of a one- versus two-parameter pilot method.
  • PURPOSE: To assess the utility of both minimum apparent diffusion coefficients (ADCs) and ADC difference values for grading astrocytic tumors at magnetic resonance imaging.
  • Fifty patients (23 male patients, 27 female patients; median age, 53 years) with newly diagnosed astrocytic tumors were evaluated.
  • Two observers blinded to clinical information independently measured the ADCs by manually placing three to five regions of interest (40-60 mm(2)) within the solid tumor either with or without contrast material-enhanced components and calculated the average ADC.
  • These ADC values were used as the parameters for tumor grading and were compared by using the Kruskal-Wallis test and receiver operating characteristic (ROC) curve analysis.
  • RESULTS: According to ROC analyses for distinguishing tumor grade, minimum ADCs showed the largest areas under the ROC curve.
  • Minimum ADCs optimally helped distinguish grade 1 from higher-grade tumors at a cutoff value of 1.47 x 10(-3) mm(2)/sec and grade 4 from lower-grade tumors at a cutoff value of 1.01 x 10(-3) mm(2)/sec (P < .001 for both).
  • ADC difference values helped distinguish grade 2 from grade 3 tumors at a cutoff value of 0.31 x 10(-3) mm(2)/sec (P < .001).
  • When tumors were graded by using the combined minimum ADC and ADC difference cutoff values mentioned above (the two-parameter method), the following positive predictive values were obtained: grade 1 tumors, 73% (eight of 11); grade 2 tumors, 100% (five of five); grade 3 tumors, 67% (eight of 12); and grade 4 tumors, 91% (20 of 22).
  • CONCLUSION: Using a combination of minimum ADCs and ADC difference values (the two-parameter method) facilitates the accurate grading of astrocytic tumors.

  • [Title] Gliosarcoma arising in oligodendroglial tumors ("oligosarcoma"): a clinicopathologic study.
  • Gliosarcomas are morphologically biphasic tumors composed of glial and sarcomatous elements.
  • Seven patients with oligodendroglial tumors and a sarcomatous component were identified.
  • At first resection, the tumors included grade II oligodendroglioma (n=3), grade III oligodendroglioma (n=1), grade II oligoastrocytoma (n=1), and grade III oligoastrocytoma (n=2).
  • The sarcomatous component developed in recurrent/progressive tumors in 6 cases but was a focal finding at first tumor resection in 1 and included fibrosarcoma (n=5), leiomyosarcoma (n=1), or pleomorphic myogenic sarcoma (n=1).
  • Rhabdoid change was a focal finding in the sarcomatous component of 1 tumor.
  • The relatively frequent presence of 1p/19q codeletion in both glial and sarcomatous components supports the notion that the sarcomatous component represents a metaplastic change occurring in the glial element, the same mechanism active in classic astrocytic gliosarcomas.

  • [Title] ABCC drug efflux pumps and organic anion uptake transporters in human gliomas and the blood-tumor barrier.
  • Delivery of therapeutic agents to the brain and its neoplasms depends on the presence of membrane transport proteins in the blood-brain barrier and in the target cells.
  • The cellular and subcellular localization of these membrane transporters determines the drug accessibility to the brain and its tumors.
  • 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.

  • In astrocytic-cell tumors, the role of autocrine and paracrine IGF-I expression in enhancing tumoral progression is well established.
  • However, the influence of systemic IGF-I levels on the clinical behavior of astrocytic neoplasms remains an open subject of research.
  • The coexistence of systemic IGF-I hypersecretion with a quick progression in the histopathological grade of the astrocytoma raises the compelling question of whether the clinical behavior of the astrocytic tumor was influenced by the acromegalic status.
  • The role of IGF-I signaling in the pathogenesis of astrocytic-cell tumors and the experience with therapeutic strategies addressing this pathway in astrocytomas are also discussed.

  • AIMS: To evaluate the expression of CD68 and kallikrein 6 in human gliomas, and investigate their prognostic significance for survival of brain cancer patients in comparison to some known prognostic markers.
  • PATIENTS AND METHODS: Histological sections of 51 primary astrocytic tumours (11 benign, 40 malignant) were immunohistochemically stained for CD68, cathepsin B, kallikrein 6 and Ki-67.
  • CD68 and kallikrein 6 expressions were also analyzed by real-time PCR in nine brain tumour biopsies.
  • RESULTS: Both microglia and tumour cells expressed CD68.
  • A CD68 staining score of tumour cells higher than 3 was a significant predictor of shorter overall survival (p<0.01) in all patients and of borderline significance in the malignant group (p=0.057).

  • OBJECTIVE: Deoxyribonucleic acid (DNA) methylation of tumor origin can be detected in the serum/plasma of cancer patients.
  • METHODS: The methylation-specific polymerase chain reaction was used to detect p16 methylation in the DNA extracted from 20 astrocytic tumors and 20 oligodendroglial tumors and the corresponding serum samples.
  • In addition, the serum DNA in 7 patients with a brainstem tumor (4 gliomas, 1 schwannoma, 1 cavernous angioma, and 1 ependymoma) was analyzed.

  • This study aimed to define the profile of their expressions, interactions and correlation with clinical features and prognostic significance in microdissected tumor samples from 84 patients with astrocytomas of different grades and from 6 white matter non-neoplasic brain tissue sample.
  • EGFR, IGFBP-2 and HIF-2A gene expression levels were analyzed by quantitative real-time PCR and differed significantly between grades I-IV astrocytic tumors (P < 0.0001, P < 0.0001 and P: 0.0013, respectively) when analyzed by the Kruskal-Wallis test.
  • Grade I astrocytomas presented gene expression levels similar to those encountered in samples of microdissected white matter of non-neoplastic brain tissue Overexpression of the EGFR, IGFBP-2 and HIF-2A genes was significantly associated with lower 2-year survival (P: 0.009, P: 0.0002 and P: 0.008, respectively).

  • [Title] Clinicopathological study of cellular proliferation and invasion in gliomatosis cerebri: important role of neural cell adhesion molecule L1 in tumour invasion.
  • BACKGROUND/AIMS: In patients with gliomatosis cerebri (GC), glial fibrillary acidic protein (GFAP) positive cells invade the entire brain, particularly the white matter.
  • METHODS: An immunohistochemical analysis of neoplastic cells from four patients with GC and 20 with astrocytic tumours using antibodies against Ki-67, GFAP, and L1, the last of which is a neural cell adhesion molecule putatively related to glioma invasion.
  • RESULTS: GC tumour cells can be divided into two types, those mainly composed of strongly GFAP and L1 positive gemistocytic cells, the other composed of small, GFAP and L1 negative spindle shaped cells.

  • Although more than 50 microarray-related studies have been carried out to characterize the molecular profiles of astrocytic tumors, we have identified only 11 that provide sound data on low-grade astrocytomas.
  • Interestingly, a group of 6 genes (TIMP4, C1NH, CHAD, THBS4, IGFBP2, and TLE2) constitute an expression profile characteristic of grade I astrocytomas as compared with all other categories of tissue (normal brain, grade II, and high-grade astrocytomas).
  • The end products (proteins) of these genes act as antimigratory compounds, a fact that could explain why pilocytic astrocytomas behave as compact (well-circumscribed) tumors as opposed to all the other astrocytic tumor types that diffusely invade the brain parenchyma.

  • Using differential methylation hybridization as a genome-wide screening approach to determine DNA methylation patterns in gliomas, we recently identified two DNA fragments in 14q23.1 (CGI-clone musical sharp396) and 14q32.12 (CGI-clone musical sharp519) that were differentially methylated between astrocytic gliomas and mixed oligoastrocytomas.
  • To validate this observation, we examined these 14q32.12 locus for methylation in an extended series of 43 astrocytic and oligodendroglial gliomas.
  • Microsatellite analysis showed LOH in seven of 28 (25%) oligodendroglial tumours and three of 15 (20%) astrocytic tumours.
  • Taken together, our data lend further support for the location of one or more yet to be identified glioma-associated tumour suppressor gene(s) on 14q.

  • OBJECTIVE: Corpora amylacea (CA) normally accumulate within perivascular, subpial, and subependymal astrocytic processes.
  • CA are associated with a number of conditions including normal aging, hippocampal sclerosis associated with temporal lobe epilepsy, multiple sclerosis, Lafora-type progressive myoclonic epilepsy, and adult polyglucosan body disease.
  • Reports of massive localized accumulation of CA in the brain outside of these conditions are rare.
  • Brain magnetic resonance imaging (MRI) revealed a left parahippocampal lesion, suggestive of low-grade glioma.
  • Specimens obtained during the operation revealed focal high-density accumulation of CA with no evidence of neoplasm, ischemia, or hypoxic injury.
  • CONCLUSION: This case illustrates the possibility that localized high-density CA accumulation can present as an intrinsic lesion on brain MRI.
  • CA should be included in the differential diagnosis for patients presenting with brain MRI suggestive of nonenhancing space-occupying lesions.

  • [Title] Minichromosome maintenance protein 3 elicits a cancer-restricted immune response in patients with brain malignancies and is a strong independent predictor of survival in patients with anaplastic astrocytoma.
  • PURPOSE: The identification of new molecular markers in astrocytic tumors may help to understand the biology of these tumors in more detail.
  • Informative tumor markers may represent prognostic factors for response to therapy and outcome as well as potential targets for novel anticancer therapies.
  • EXPERIMENTAL DESIGN: Tumor-associated antigens were identified by immunoscreening of a human glioma cDNA expression library with allogeneic sera from patients with diffuse astrocytoma (WHO grades 2-4).
  • In addition, 98 serum specimens from patients with primary and secondary brain malignancies and 30 serum specimens from healthy controls were examined by serologic immunoscreening for immunoreactivity with MCM3.
  • RESULTS: MCM3 is overexpressed in human astrocytic tumors and elicits a cancer-restricted humoral immune response in 9.3% (9 of 97) of patients with brain tumors (n = 95) and brain metastases (n = 2) but not in healthy controls.

  • [Title] Selective cancer-germline gene expression in pediatric brain tumors.
  • Cancer-germline genes (CGGs) code for immunogenic antigens that are present in various human tumors and can be targeted by immunotherapy.
  • Their expression has been studied in a wide range of human tumors in adults.
  • We measured the expression of 12 CGGs in pediatric brain tumors, to identify targets for therapeutic cancer vaccines.
  • Real Time PCR was used to quantify the expression of genes MAGE-A1, MAGE-A2, MAGE-A3, MAGE-A4, MAGE-A6, MAGE-A10, MAGE-A12, MAGE-C2, NY-ESO-1 and GAGE-1,2,8 in 50 pediatric brain tumors of different histological subtypes.
  • Fifty-five percent of the medulloblastomas (n = 11), 86% of the ependymomas (n = 7), 40% of the choroid plexus tumors (n = 5) and 67% of astrocytic tumors (n = 27) expressed one or more CGGs.
  • With exception of a minority of tumors, the overall level of CGG expression in pediatric brain tumors was low.
  • CGG-encoded antigens are therefore suitable targets in a very selected group of pediatric patients with a brain tumor.
  • Interestingly, glioblastomas from adult patients expressed CGGs more often and at significantly higher levels compared to pediatric glioblastomas.
  • This observation is in line with the notion that pediatric and adult glioblastomas develop along different genetic pathways.

  • [Title] Molecular genetic analysis of p53 intratumoral heterogeneity in human astrocytic brain tumors.
  • We investigated genetic heterogeneity of astrocytic gliomas using p53 gene mutations as a marker.
  • Different parts of morphologically heterogeneous astrocytic gliomas were microdissected, and direct DNA sequencing of p53 gene exons 5 through 8 was performed.
  • Thirty-five glioma samples and tumor-adjacent normal-appearing brain tissue from 11 patients were analyzed.
  • We found that some tumors were devoid of p53 gene mutations, whereas other tumors carried 1 or often several (up to 3) different mutations.
  • The mutations were present in grade II, III, and IV astrocytic glioma areas.
  • Both severe functionally dead mutants and mutants with remaining transcriptional activity could be observed in the same tumor.
  • These results support the notion that intratumoral heterogeneity in brain tumors originates from different molecular defects.

  • [Title] Expression of EphA2 in human astrocytic tumors: correlation with pathologic grade, proliferation and apoptosis.
  • A high expression of EphA2 has been detected in many non-central nervous system tumors; however, the EphA2 expression in brain astrocytic tumors remains unclear.
  • In this study, we investigated the expression of EphA2 mRNA and protein in 90 cases of human astrocytic tumors by reverse transcription polymerase chain reaction and immunohistochemistry, respectively.
  • The proliferative index (PI) of tumor cells was evaluated by Ki-67 immunohistochemistry, and the apoptotic index (AI) was determined by TdT-mediated dUTP nick end labeling assay.
  • The correlation between EphA2 expression, pathologic grade, proliferation and apoptosis of astrocytic tumors was further analyzed.
  • Therefore, EphA2 may be a new biomarker for astrocytic tumors.
  • It may also affect the proliferation and apoptosis of tumor cells and be an attractive therapy target for astrocytic tumors.

  • [Title] Outcome-based profiling of astrocytic tumours identifies prognostic gene expression signatures which link molecular and morphology-based pathology.
  • Astrocytomas are intracranial malignancies for which invasive growth and high motility of tumour cells preclude total resection; the tumours usually recur in a more aggressive and, eventually, lethal form.
  • In order to identify novel molecular markers for prognosis we obtained expression profiles of: i) tumours associated with particularly long recurrence-free intervals, ii) tumours which led to rapid patient death, and iii) tumour-free control brain.
  • Our finding of cell-specificity for some of these outcome-determining genes relates global expression data to the presence of morphological correlates of tumour behaviour and, thus, provides a link between morphology-based and molecular pathology.

  • [Title] Chromosome DNA imbalances in human astrocytic tumors: a comparative genomic hybridization study of 63 Chinese patients.
  • Astrocytic tumors are the most frequent primary brain neoplasms.
  • Analysis of chromosome DNA imbalance may help to advance diagnosis, grading, and classification, and to determine appropriate therapeutic approaches for tumors of astrocytic lineages.
  • Comparative genomic hybridization (CGH) provides comprehensive information about chromosome DNA aberrations, and is an important technique for evaluating the differences at genomic levels among the same or different grade tumors.
  • In this study, 63 astrocytic tumors of Chinese patients were screened by CGH, and the relationship between their chromosome DNA imbalances and the histopathological classification, grading, and clinical features was analyzed.
  • Most tumors showed genomic copy aberrations detected by CGH.
  • This study confirmed that chromosomal aberrations, such as +1q, -4q, -10q, +7p, and -15q possibly contributed to the pathogenesis of these tumors.
  • Our data was the first report on the chromosomal aberrations of astrocytic tumors of Chinese patients.
