  • [Title] The differences of water diffusion between brain tissue infiltrated by tumor and peritumoral vasogenic edema.
  • The differences between peritumoral brain tissue infiltrated by tumor and vasogenic edema were prospectively evaluated by comparing the apparent diffusion coefficient (ADC) of peritumoral areas of infiltrative tumors (anaplastic astrocytomas and glioblastomas) to that of peritumoral areas of noninfiltrative tumors (metastatic carcinomas) on 54 patients.
  • Peritumoral ADCs indicated the possibility of differentiation between tumor infiltration and vasogenic edema, as well as between primary gliomas and metastases.

  • [Title] Temozolomide: The evidence for its therapeutic efficacy in malignant astrocytomas.
  • INTRODUCTION: Malignant gliomas are a heterogeneous group of primary central nervous system neoplasms that represent less than 2% of all cancers yet carry a significant burden to society.
  • Temozolomide (TMZ) is a new second generation DNA alkylating agent that has become part of malignant astrocytoma management paradigms because of its proven efficacy, ease of administration, and favorable toxicity profile.
  • AIMS: To review the role of TMZ in the management of malignant astrocytomas (World Health Organization grades III and IV) including newly diagnosed (n) and recurrent (r) anaplastic astrocytomas (AA) and glioblastomas.
  • EVIDENCE REVIEW: A series of pivotal clinical trials have established a role for TMZ in the treatment of malignant astrocytomas.
  • A recent large prospective randomized phase III trial showed that the addition of TMZ during and after radiation therapy (RT) in newly diagnosed (nGBM) patients prolonged median overall survival by 2.5 months; perhaps more importantly, the 2-year survival rate for patients receiving TMZ and RT was 26% compared with 10% for those receiving RT alone.

  • [Title] Vascular endothelial growth factor and basic fibroblast growth factor expression positively correlates with angiogenesis and peritumoural brain oedema in astrocytoma.
  • BACKGROUND: Astrocytoma is the most malignant intracranial neoplasm and is characterized by high neovascularization and peritumoural brain oedema.
  • METHODS: The expression of two angiogenic growth factors, vascular endothelial growth factor and basic fibroblast growth factor were investigated using immunohistochemistry for astrocytoma from 82 patients and 11 normal human tissues.
  • RESULTS: The expression of vascular endothelial growth factor and basic fibroblast growth factor positively correlate with the pathological grade of astrocytoma, microvessel density numbers and brain oedema, which may be responsible for the increased tumour neovascularization and peritumoural brain oedema.
  • CONCLUSION: The results support the idea that inhibiting vascular endothelial growth factor and basic fibroblast growth factor are useful for the treatment of human astrocytoma and to improve patient's clinical outcomes and prognosis.

  • [Title] PBEF1/NAmPRTase/Visfatin: a potential malignant astrocytoma/glioblastoma serum marker with prognostic value.
  • Malignant astrocytomas comprise anaplastic astrocytoma (AA; grade III) and Glioblastoma (GBM; grade IV).
  • GBM is the most malignant with a median survival of 10-12 months in patients.
  • Using cDNA microarray based expression profiling of different grades of astrocytomas, we identified several fold increased levels of PBEF1 transcripts in GBM samples.
  • Further validation using real time RT-qPCR on an independent set of tumor samples (n=91) and normal brain samples (n=9), GBM specific higher expression of PBEF1 was confirmed.
  • We carried out ELISA analysis on serum samples of astrocytoma patients to determine whether this protein levels would correlate with the presence of tumor and tumor grade.
  • Statistical analysis of these data indicates that in patients with astrocytoma, serum PBEF1 levels correlate with tumor grade and is highest in GBM.
  • Immunohistochemical analysis of an independent set of 51 retrospective GBM cases with known survival data revealed that PBEF1 expression in the tumor tissue along with its co-expression with p53 was associated with poor survival.
  • Thus, we have identified PBEF1 as a potential malignant astrocytoma serum marker and prognostic indicator among GBMs.

  • [Title] Neuropeptide Y receptors in primary human brain tumors: overexpression in high-grade tumors.
  • World Health Organization Grade IV glioblastomas showed a remarkably high expression of the NPY receptor subtype Y2 with respect to both incidence (83%) and density (mean, 4,886 dpm/mg tissue); astrocytomas World Health Organization Grades I to III and oligodendrogliomas also exhibited high Y2 incidences but low Y2 densities.
  • In conclusion, Y2 receptors in glioblastomas that are activated by NPY originating from intratumoral nerve fibers might mediate functional effects on the tumor cells.
  • Moreover, identification of the high expression of NPY receptors in high-grade gliomas and embryonal brain tumors provides the basis for in vivo targeting.

  • According to the current WHO classification anaplastic gliomas comprise pure astrocytomas and oligodendrogliomas and mixed tumors.
  • This review summarizes findings, discusses problems and defines new questions from the phase III trials on anaplastic gliomas.
  • Therefore, marker profiles should be included into the next WHO brain tumor classification.
  • The current standard of care for first-line treatment in anaplastic gliomas is radiotherapy or chemotherapy.
  • Inclusion in this trial is already based on the WHO grade and the 1p/19q status and not on the histopathological subtype.
  • Furthermore, anaplastic gliomas are an important group of brain tumors for developing future molecular targeted therapies and should therefore be in the main focus of academic and industrial drug development, which aims at improved efficacy and avoiding long-term side-effects.

  • Malignant gliomas are the most frequent primary brain tumors in adults.
  • Temozolomide is an oral alkylating cytotoxic agent of second generation, used in the treatment of high-grade gliomas.
  • It is indicated in newly diagnosed glioblastoma multiform as well as in recurrent or progressive malignant gliomas, such as glioblastoma multiform or anaplastic astrocytoma.
  • The literature review was analysed by experts who determined the evidence level (A to E) according to the scale of recommendations adopted by the "Haute Autorité de santé--HAS--(French National Authority for Health)".
  • For high-grade and low-grade gliomas, based on the level of evidence from the literature, the use of temozolomide can be justified, with a B2 score attributed to these indications.

  • More recently, case reports have described malignant gliomas arising after irradiation and recurrences following subtotal or even gross total resection.
  • Nonetheless, a probably radiation induced anaplastic astrocytoma was encountered in one case 7 years after therapy.
  • These findings suggest that these patients may need closer follow-up than initially suggested, lending further support to the notion that this tumor behaves more like a benign neoplasm, rather than a dysplastic or hamartomatous lesion.

  • [Title] Concurrent sequence variation of TP53 and TP73 genes in anaplastic astrocytoma.
  • Disruption or loss of tumor suppressor gene TP53 is implicated in the development or progression of almost all different types of human malignancies.
  • Using PCR-SSCP and gene sequencing, we analyzed the TP53 and TP73 genes in a case of a grade III anaplastic astrocytoma that progressed to glioblastoma.
  • The mutation found at exon 6 of the gene TP53 could be associated with the rapid tumoral progression found in this case, since the mutated p53 may inactivate the wild-type p53 and the p73alpha protein, which was conserved here, leading to an increase in cellular instability.

  • [Title] Induction of gliosarcoma and atypical meningioma 13 years after radiotherapy of residual pilocytic astrocytoma in childhood.
  • BACKGROUND: Malignant transformation of pilocytic astrocytomas in children is rare and often linked to previous radiotherapy.
  • METHODS AND RESULTS: We report a patient who underwent subtotal resection of a right temporal and insular pilocytic astrocytoma at age 8 in 1988 followed by high-dose radiation therapy.
  • A local recurrence, grade WHO III, with signs of focal sarcomatous transformation, was subtotally resected 13 years later in 2001.
  • A new and fast growing right frontal meningioma, grade WHO II, was removed in 2003.
  • Another tumor mass reduction in 2005 was followed by stereotactic radiotherapy.
  • CONCLUSION: Most of the reported cases of malignant transformation of pilocytic astrocytomas received radiation therapy beforehand.
  • Irradiation-induced meningiomas in children are known to occur, however not following radiotherapy of low-grade hemispheric gliomas.
  • The presented case illustrates why adjuvant radiotherapy of residual pilocytic astrocytoma in children is not recommended anymore.

  • [Title] Meta-analysis of glioblastoma multiforme versus anaplastic astrocytoma identifies robust gene markers.
  • BACKGROUND: Anaplastic astrocytoma (AA) and its more aggressive counterpart, glioblastoma multiforme (GBM), are the most common intrinsic brain tumors in adults and are almost universally fatal.
  • A deeper understanding of the molecular relationship of these tumor types is necessary to derive insights into the diagnosis, prognosis, and treatment of gliomas.
  • Although genomewide profiling of expression levels with microarrays can be used to identify differentially expressed genes between these tumor types, comparative studies so far have resulted in gene lists that show little overlap.
  • CONCLUSION: We have performed a meta-analysis of genome-scale mRNA expression data for 289 human malignant gliomas and have identified a list of >900 probe sets and >20 pathways that are significantly different between GBM and AA.
  • These feature lists could be utilized to aid in diagnosis, prognosis, and grade reduction of high-grade gliomas and to identify genes that were not previously suspected of playing an important role in glioma biology.

  • [Title] Evaluation of invasiveness of astrocytoma using 1H-magnetic resonance spectroscopy: correlation with expression of matrix metalloproteinase-2.
  • INTRODUCTION: Even low-grade astrocytomas infiltrate the entire brain, a feature that precludes their successful therapy.
  • So to assess the invasive potential of astrocytoma is very important.
  • The aim of this study was determine whether there is a significant correlation between the results of (1)H-magnetic resonance spectroscopy ((1)H-MRS) and tumor invasive potential of astrocytoma, which is reflected by expression of matrix metalloproteinase-2 (MMP-2).
  • METHODS: The (1)H-MRS spectra of 41 histologically verified astrocytomas were obtained on a 3-T MR scanner.
  • According to the World Health Organization classification criteria for central nervous system tumors, there were 16 low-grade astrocytomas (2 pilocytic astrocytomas, 14 grade II astrocytomas) and 25 high-grade astrocytomas (5 anaplastic astrocytomas, 20 glioblastomas).The choline/N-acetylaspartate (Cho/NAA) and choline/creatine (Cho/Cr) ratios were calculated.
  • Of the 41 astrocytomas, 19 (8 low-grade and 11 high-grade) were analyzed immunohistochemically.
  • The correlations between metabolite ratios and the quantitative data from the immunohistochemical tests in the 19 astrocytomas were determined.
  • RESULTS: The Cho/NAA and Cho/Cr ratios of high-grade astrocytoma were both significantly greater than those of low-grade astrocytoma (t = -6.222, P = 0.000; t = -6.533, P = 0.000, respectively).
  • MMP-2 COD values of high-grade astrocytomas were also significantly greater than those of low-grade astrocytomas (t = -5.892, P = 0.000).
  • CONCLUSION: (1)H-MRS is helpful in evaluating the invasiveness of astrocytomas and predicting prognosis preoperatively by determining the Cho/NAA and Cho/Cr ratios.

  • METHOD: We report on 6 patients (3 men) diagnosed with malignant astrocytoma.
  • With the gamma probe we confirmed the tumor uptake, and a biopsy sample was taken.
  • After conventional tumor resection, we scanned the surgical bed with the gamma probe.
  • RESULTS: In all patients the biopsy confirmed a high-grade astrocytoma.
  • In all cases we found residual uptake in the surgical bed that was confirmed as residual tumor by pathologic examination.

  • [Title] Regulation of progesterone receptor isoforms content in human astrocytoma cell lines.
  • Both PR isoforms have been detected in human astrocytomas, the most common and aggressive primary brain tumours, but their regulation and function are unknown.
  • We studied the effects of estradiol, progesterone and their receptor antagonists (ICI 182,780 and RU 486) on PR isoforms content in U373 and D54 human astrocytoma cell lines, respectively derived from grades III and IV astrocytomas, by Western blot analysis.
  • Our results suggest a differential PR isoforms regulation depending on the evolution grade of human astrocytoma cells, and an inhibitory role of PR-A on progesterone effects on astrocytomas cell growth.

  • DcR3 has been demonstrated to produce a secreted member of the tumor necrosis factor receptor superfamily that negatively regulates Fas-mediated apoptosis.
  • In this study we examined DcR3 gene amplification, DcR3 mRNA expression, and DcR3 protein expression in 46 human astrocytic brain tumors by quantitative genomic PCR, quantitative reverse transcription-PCR, and immunohistochemistry, respectively.
  • The DcR3 gene amplification was detected in none of 6 (0%) low-grade astrocytomas, 1 of 16 (6%) anaplastic astrocytomas, and 6 of 24 ( 25%) glioblastomas.
  • We thus concluded that high DcR3 mRNA expression and protein expression may be positively related to the gene amplification in astrocytic brain tumors, especially glioblastomas.
  • Further, we speculated that the DcR3 gene amplification with overexpression may be responsible for malignant features in glioblastomas.

  • [Title] Methylation of the PTEN promoter defines low-grade gliomas and secondary glioblastoma.
  • Glioblastoma multiforme (GBM) can present as either de novo or secondary tumors arising from previously diagnosed low-grade gliomas.
  • Although these tumor types are phenotypically indistinguishable, de novo and secondary GBMs are associated with distinct genetic characteristics.
  • PTEN mutations, which result in activation of the phosphoinositide 3-kinase (PI3K) signal transduction pathway, are frequent in de novo but not in secondary GBMs or their antecedent low-grade tumors.
  • Results we present here show that grade II astrocytomas, oligodendrogliomas, and oligoastrocytomas commonly display methylation of the PTEN promoter, a finding that is absent in nontumor brain specimens and rare in de novo GBMs.
  • Our results also demonstrate frequent methylation of the PTEN promoter in grade III astrocytomas and secondary GBMs, consistent with the hypothesis that these tumors arise from lower grade precursors.
  • PTEN methylation is rare in de novo GBMs and is mutually exclusive with PTEN mutations.
  • We conclude that methylation of the PTEN promoter may represent an alternate mechanism by which PI3K signaling is increased in grade II and III gliomas as well as secondary GBMs, a finding that offers new therapeutic approaches in these patients.

  • At the present time, there are no proven beneficial effects of chemotherapy (CT) for the treatment of pure low-grade astrocytomas.
  • Brain radiotherapy (RT) still remains the standard treatment in order to reduce or delay tumor progression or symptoms, despite possible long-term neurologic complications.
  • We report 10 patients, with histologically proven pure low-grade fibrillary astrocytomas, to which we administered a first-line nitrosourea-based CT.
  • CT was well tolerated; all patients developed myelosuppression with 40% of grade III/IV hematotoxicity.
  • These results demonstrate that some patients with symptomatic non-resectable fibrillary low-grade astrocytomas can be treated with up-front CT to improve their neurologic status.

  • [Title] Decreased levels of interleukin-10 and transforming growth factor-beta 2 in cerebrospinal fluid of patients with high grade astrocytoma.
  • It is unknown if production of these cytokines is limited to the site of tumor or these molecules are also released to cerebrospinal fluid and blood.
  • The goal of our study was to determine if patients with astrocytoma have increased levels of IL-10 and TGF-beta 2 in cerebrospinal fluid (CSF) and serum.
  • METHODS: CSF and serum samples were taken from 16 patients with astrocytoma of grade III or grade IV according to the WHO classification and from 28 age- and gender-matched controls (patients with normal pressure hydrocephalus or with lumbar disk herniation).
  • Patients with astrocytoma had decreased levels of IL-10 (0.9 +/- 1.2 versus 3.5 +/- 9.2 pg/ml, p=0.01) and TGF-beta 2 (0.0 +/- 0.0 versus 5.4 +/- 9.4 pg/ml, p=0.05) in CSF compared to controls.
  • Because serum IL-10 and TGF-beta 2 levels are similar in patients with astrocytoma and in controls, these cytokines are probably not directly involved in peripheral monocyte and T cell deactivation.

  • [Title] Combined treatment of pediatric high-grade glioma with the oncolytic viral strain MTH-68/H and oral valproic acid.
  • The case of a 12-year-old boy with anaplastic astrocytoma of the left thalamus is reported.
  • Postoperative irradiation and chemotherapy could not repress tumor progression; therefore, treatment was undertaken with an oncolytic virus, MTH-68/H, an attenuated strain of Newcastle disease virus (NDV), and valproic acid (VPA), an antiepileptic drug, which also has antineoplastic properties.
  • This treatment resulted in a far-reaching regression of the thalamic glioma, but 4 months later a new tumor manifestation, an extension of the thalamic tumor, appeared in the wall of the IVth ventricle, which required a second neurosurgical intervention.
  • Under continuous MTH-68/H - VPA administration the thalamic tumor remained under control, but the rhombencephalic one progressed relentlessly and led to the fatal outcome.
  • In the final stage, a third tumor manifestation appeared in the left temporal lobe.
  • The possible reasons for the antagonistic behavior of the three manifestations of the same type of glioma to the initially most successful therapy are discussed.
  • The comparative histological study of the thalamic and rhombencephalic tumor manifestations revealed that MTH-68/H treatment induces, similar to in vitro observations, a massive apoptotic tumor cell decline.
  • In the rhombencephalic tumor, in and around the declining tumor cells, NDV antigen could be demonstrated immunohistochemically, and virus particles have been found in the cytoplasm of tumor cells at electron microscopic investigation.

  • Stereotactic biopsies of the brainstem were performed; the findings of abundant Rosenthal fibers, interjacent spindle-shaped and gemistocytic cells partially with dark and irregularly formed nuclei favored primarily the diagnosis of a malignant astrocytoma, although a demyelinating disease could not be definitely excluded.

  • [Title] WT1 expression distinguishes astrocytic tumor cells from normal and reactive astrocytes.
  • Particularly in small brain biopsies, it might be difficult to distinguish reactive astrogliosis from low-grade or infiltration zones of high-grade astrocytomas.
  • Recently, the over-expression of Wilms' tumor gene product WT1 was reported in astrocytic tumor cells.
  • Therefore, we investigated WT1 expression in paraffin-embedded brain sections from 28 controls, 48 cases with astrogliosis of various etiology and 219 astrocytomas [World Health Organization (WHO) grades I-IV] by immunohistochemistry.
  • In astrocytomas, WT1-positive tumor cells were found in pilocytic astrocytomas (66.7% of cases), diffuse astrocytomas (52.7%) WHO grade II (52.7%), anaplastic astrocytomas (83.4%) and glioblastomas (98.1%).
  • Overall, the majority of all astrocytic neoplasms (84.5%) expressed WT1.
  • Establishing a cut-off value of 0% immunoreactive tumor cells served to recognize neoplastic astrocytes with 100% specificity and 68% sensitivity and was associated with positive and negative predictive values of 1 and 0.68, respectively.

  • [Title] Perfusion and diffusion MR imaging in enhancing malignant cerebral tumors.
  • OBJECTIVE: Common contrast-enhancing malignant tumors of the brain are glioblastoma multiforme (GBMs), anaplastic astrocytomas (AAs), metastases, and lymphomas, all of which have sometimes similar conventional MRI findings.
  • Our aim was to evaluate the role of perfusion MR imaging (PWI) and diffusion-weighted imaging (DWI) in the differentiation of these contrast-enhancing malignant cerebral tumors.
  • Minimum ADC values (ADC(min)) of each tumor was later calculated from ADC map images.
  • PWI was applied using dynamic susceptibility contrast technique and maximum relative cerebral blood volume (rCBV(max)) was calculated from each tumor, given in ratio with contralateral normal white matter.
  • CONCLUSION: Combination of DWI and PWI, with ADC(min) and rCBV(max) calculations, may aid routine MR imaging in the differentiation of common cerebral contrast-enhancing malignant tumors.

  • [Title] Preoperative grading of presumptive low-grade astrocytomas on MR imaging: diagnostic value of minimum apparent diffusion coefficient.
  • BACKGROUND AND PURPOSE: Histopathologic grade of glial tumors is inversely correlated with the minimum apparent diffusion coefficient (ADC).
  • We assessed the diagnostic values of minimum ADC for preoperative grading of supratentorial astrocytomas that were diagnosed as low-grade astrocytomas on conventional MR imaging.
  • MATERIALS AND METHODS: Among 118 patients with astrocytomas (WHO grades II-IV), 16 who showed typical MR imaging findings of low-grade supratentorial astrocytomas on conventional MR imaging were included.
  • The minimum ADC value of each tumor was determined from several regions of interest in the tumor on ADC maps.
  • To assess the relationship between the minimum ADC and tumor grade, we performed the Mann-Whitney U test.
  • A receiver operating characteristic (ROC) analysis was used to determine the cutoff value of the minimum ADC that had the best combination of sensitivity and specificity for distinguishing low- and high-grade astrocytomas.
  • RESULTS: Eight of the 16 patients (50%) were confirmed as having high-grade astrocytomas (WHO grades III and IV), and the other 8 patients were confirmed as having low-grade astrocytomas (WHO grade II).
  • The median minimum ADC of the high-grade astrocytoma (1.035 x 10(-3) mm(2) .
  • sec(-1)) group was significantly lower than that of the low-grade astrocytoma group (1.19 x 10(-3) mm(2) .
  • CONCLUSION: Measuring minimum ADC can provide valuable diagnostic information for the preoperative grading of presumptive low-grade supratentorial astrocytomas.

  • [Title] Pilot trial of the rate of response, safety, and tolerability of temozolomide and oral VP-16 in patients with recurrent or treatment-induced malignant central nervous system tumors.
  • METHODS: Eleven patients with recurrent or treatment-induced malignant CNS tumors, including treatment-induced PNET (in 1 patient), brainstem glioma (in 3 patients; 1 with treatment-induced, 2 with recurrence), recurrent anaplastic astrocytoma (in 3 patients), and recurrent glioblastoma (in 4 patients) were evaluated in a pilot study of TMZ and oral VP-16 chemotherapy.
  • The histologic subtype of the tumor, its location, and its maximum response to chemotherapy did not have an impact on the duration of disease control.
  • CONCLUSION: This limited pilot study confirms the innocuousness and the activity of the combination of TMZ and oral VP-16 in recurrent malignant brain tumors.
  • This promising activity warrants further investigation of this combination in larger phase II or III studies.

  • [Title] Immunohistochemical appearance of HNE-protein conjugates in human astrocytomas.
  • Those of astrocytic origin are the most widespread of primary brain tumors and account for more then 60% of all CNS neoplasms.
  • The current state of knowledge on the associations between tumor etiology and oxidative stress suggests that environmental factors that cause oxidative stress could also induce and promote cancer, especially in case of hereditary predisposition.
  • The aim of present study was to investigate by immunohistochemistry the presence of HNE-modified proteins in different types of astrocytoma.
  • Our study comprised 45 astrocytic tumors.
  • These tumors were graded in accordance with the WHO classification as diffuse astrocytomas (DA), anaplastic astrocytomas (AA) and glioblastomas (GB), while each group comprised 15 tumors.
  • Slides of paraffin-embedded tumor tissue were stained with hematoxylin-eosin or were prepared for immunohistochemistry with monoclonal antibodies to HNE-histidine conjugate.
  • HNE positivity was proportional with malignancy of astrocytomas.
  • Lowest intensity of HNE immunopositivity was present in tumor cells of almost all DA, predominantly around blood vessels.
  • In malignant variants of astrocytoma, AA and GB, HNE positivity was moderate to strong, and diffusely distributed in all tumors.

  • The expression levels of these genes in 152 gliomas (100 glioblastomas, 21 anaplastic astrocytomas, 19 diffuse astrocytomas, and 12 anaplastic oligodendrogliomas) were measured using adapter-tagged competitive polymerase chain reaction, a high-throughput reverse transcription-polymerase chain reaction technique.
  • The gene expression profiling identified clinically informative prognostic molecular features in astrocytic and oligodendroglial tumors that were more reliable than the traditional histological classification scheme.
