Abstract
Background This investigator-initiated, open-label, single-arm, single-institute study was conducted to investigate the effectiveness of induction combination chemoradiotherapy and long-term maintenance therapy with temozolomide (TMZ) plus interferon (IFN)-β for glioblastoma. Methods The initial induction combination chemoradiotherapy comprised radiotherapy plus TMZ plus vincristine plus IFN-β. Maintenance chemotherapy comprised monthly TMZ, continued for 24–50 cycles, plus weekly IFN-β continued for as long as possible. The primary endpoint was 2-year overall survival (2y-OS). The study protocol was to be considered valid if the expected 2y-OS was over 38% and the lower limit of the 95% confidence interval (CI) was no less than 31.7% compared with historical controls, using Kaplan-Meier methods. Secondary endpoints were median progression-free survival (mPFS), median OS (mOS), 5-year OS rate (5y-OS), and mPFS and mOS classified according to MGMT promoter methylation status. Results Forty-seven patients were analyzed. The 2y-OS was 40.7% (95%CI, 27.5–55.4%). The mPFS and mOS were 11.0 months and 18.0 months, respectively, and 5y-OS was 20.3% (95%CI, 10.9–34.6%). The mPFS in groups with and without MGMT promoter methylation in the tumor was 10.0 months and 11.0 months (p = 0.59), respectively, and mOS was 24.0 months and 18.0 months (p = 0.88), respectively. The frequency of grade 3/4 neutropenia was 19.1%. Conclusions The 2y-OS with induction multidrug combination chemoradiotherapy and long-term maintenance therapy comprising TMZ plus IFN-β tended to exceed that of historical controls, but the lower limit of the 95%CI was below 31.7%. Although the number of cases was small, this protocol may rule out MGMT promoter methylation status as a prognostic factor.

Abstract
BACKGROUND We previously reported that the absolute value of O<sup>6</sup>-methylguanine-DNA methyltransferase (MGMT) messenger RNA (mRNA) obtained using real-time reverse transcription polymerase chain reaction (RT-PCR) might be useful for predicting both the prognosis and the results of therapy for glioblastoma (GB) treated by temozolomide (TMZ). METHODS MGMT mRNA was measured in 55 newly diagnosed cases of GB less than 75 and had a Karnofsky performance status (KPS) of at least 60 by real-time reverse transcription polymerase chain reaction (RT-PCR) using the TaqMan probe. A receiver operating characteristic analysis was performed to determine the cutoff points for progression free survival (PFS) and overall survival (OS). RESULTS In 55 patients with GB, 1200 and 3600 for PFS, 1200, 2100 and 2900 copies/μgRNA for OS were the candidate cutoff points. Significantly longer PFS and OS were observed in patients who did not exceed 1200 copies/μg RNA. CONCLUSIONS One thousand and two hundred copies/μg RNA appeared to be the most reasonable cutoff point of MGMTmRNA in GB for deciding to use other anti-tumor drugs such as Bevacizumab together with TMZ.

Abstract
The prognosis of gioblastoma, the standard chemotherapy agent for which is temozolomide (TMZ), remains poor despite recent advances in multimodal treatments. Therefore, it is necessary to identify and develop novel therapeutics for this malignant disease. Ribavirin, an anti-viral agent which is one of the standard agents for treatment of chronic hepatitis C in combination with interferon (IFN), was recently revealed to have an antitumor potential towards various tumor cells, including malignant glioma cells. The aim of the present study was to examine the antitumor effect of ribavirin in combination with TMZ and IFN-β on glioma cells and to evaluate the possibility that such combinations might represent a novel candidate for glioblastoma therapy. The combination of ribavirin with TMZ and IFN-β displayed a significant cell growth inhibitory effect with a ribavirin dose-dependency, including a relatively low concentration of ribavirin, on not only TMZ-sensitive but also TMZ-resistant malignant glioma cells. The antitumor efficacy of such a combination further indicated a synergistic interaction when assessed by the Chou-Talalay method. Furthermore, flow cytometry analysis suggested that apoptosis induction was one of the possible biological processes underlying the synergistic antitumor effect of these triple combination treatments. Therefore, such combinations may be potentially important in the clinical setting for glioblastoma treatment, although further detailed studies, e.g. on the adverse effects, are required.

Abstract
Radiation therapy has been linked to the induction of an intratumoral type I interferon (IFN) response, which positively affects the response to treatment. This has spiked the interest to combine radiation therapy with IFN-based treatment. Interestingly, this combination treatment has been considered previously, since preclinical studies demonstrated a radiosensitizing effect of interferons. As a result, multiple clinical trials have been performed combining radiation therapy with interferons in different tumor types. Although potential benefit has been suggested, the outcomes of the trials are diverse and challenging to interpret. In addition, increased grade ≥3 toxicity frequently resulted in a negative recommendation regarding the combination therapy. The latter appears premature because many studies were small and several aspects of the combination treatment have not yet been sufficiently explored to justify such a definite conclusion. This review summarizes the available literature on this combination therapy, with a focus on IFN-α and IFN-β. Based on preclinical studies and clinical trials, we evaluated the potential opportunities and describe the current challenges. In addition, we identify several issues that should be addressed to fully exploit the potential benefit of this combinatorial treatment approach.

IFN‑β sensitizes TRAIL‑induced apoptosis by upregulation of death receptor 5 in malignant glioma cells. Oncol Rep 2019; 42:2635-2643. [PMID: 31638255 PMCID: PMC6859459 DOI: 10.3892/or.2019.7383] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/24/2019] [Accepted: 09/30/2019] [Indexed: 12/15/2022] Open
Abstract
Tumor necrosis factor‑related apoptosis‑inducing ligand (TRAIL), a member of the tumor necrosis factor (TNF) family, induces apoptosis in cancer cells by binding to its receptors, death receptor 4 (DR4) and DR5, without affecting normal cells, and is therefore considered to be a promising antitumor agent for use in cancer treatment. However, several studies have indicated that most glioma cell lines display resistance to TRAIL‑induced apoptosis. To overcome such resistance and to improve the efficacy of TRAIL‑based therapies, identification of ideal agents for combinational treatment is important for achieving rational clinical treatment in glioblastoma patients. The main aim of this study was to investigate whether interferon‑β (IFN‑β) (with its pleiotropic antitumor activities) could sensitize malignant glioma cells to TRAIL‑induced apoptosis using glioma cell lines. TRAIL exhibited a dose‑dependent antitumor effect in all of the 7 types of malignant glioma cell lines, although the intensity of the effect varied among the cell lines. In addition, combined treatment with TRAIL (low clinical dose: 1 ng/ml) and IFN‑β (clinically relevant concentration: 10 IU/ml) in A‑172, AM‑38, T98G, U‑138MG and U‑251MG demonstrated a more marked antitumor effect than TRAIL alone. Furthermore, the antitumor effect of the combined treatment with TRAIL and IFN‑β may be enhanced via an extrinsic apoptotic system, and upregulation of DR5 was revealed to play an important role in this process in U‑138MG cells. These findings provide an experimental basis to suggest that combined treatment with TRAIL and IFN‑β may offer a new therapeutic strategy for malignant gliomas.

Abstract
Malignant melanoma is a highly aggressive skin cancer that is highly resistant to chemotherapy. Adjuvant therapy is administered to patients with melanoma that possess no microscopic metastases or have a high risk of developing microscopic metastases. Methylating agents, including dacarbazine (DTIC) and temozolomide (TMZ), pegylated interferon (IFN)‑α2b and interleukin‑2 have been approved for adjuvant immuno‑chemotherapy; however, unsatisfactory results have been reported following the administration of methylating agents. IFN‑β has been considered to be a signaling molecule with an important therapeutic potential in cancer. The aim of the present study was to elucidate whether antitumor effects could be augmented by the combination of TMZ and IFN‑β in malignant melanoma. We evaluated the efficacy of TMZ and IFN‑β by comparing O6‑methylguanine‑DNA transferase (MGMT)‑proficient and ‑deficient cells, as MGMT has been reported to be associated with the resistance to methylating agents. Cell viability was determined by counting living cells with a Coulter counter, and apoptosis was analyzed by dual staining with Annexin V Alexa Fluor® 488 and propidium iodide. The expression of proteins involved in the cell cycle, apoptosis and autophagy was evaluated by western blot analysis. The combined treatment with TMZ and IFN‑β suppressed cell proliferation and induced cell cycle arrest. We also demonstrated that a combination of TMZ and IFN‑β enhanced apoptosis and autophagy more efficiently compared with TMZ treatment alone. These findings suggest that antitumor activity may be potentiated by IFN‑β in combination with TMZ.

Abstract
PURPOSE A major adverse effect arising from nimustine hydrochloride (ACNU) therapy for brain tumors is myelosuppression. Because its timing and severity vary among individual patients, the ACNU dose level has been adjusted in an empiric manner at individual medical facilities. To our knowledge, ours is the first study to develop a machine-learning approach to estimate myelosuppression through analysis of patient factors before treatment and attempts to clarify the relationship between myelosuppression and hematopoietic stem cells from daily clinical data. Adverse effect prediction will allow ACNU dose adjustment for patients predicted to have decreases in blood cell counts and will enable focused follow-up of patients undergoing chemoradiotherapy. PATIENTS AND METHODS Patients were newly pathologically diagnosed with WHO grade 2 or 3 tumors and were treated with ACNU-based chemoradiotherapy. For detailed analysis of the timing and intensity of adverse effects in patients, we developed a data-weighted support vector machine (SVM) based on adverse event criteria (nadir-weighted SVM [NwSVM]). To evaluate the estimation accuracy of blood cell count dynamics, the determination coefficient ( r2) between real and estimated data was calculated by three regression methods: polynomial, SVM, and NwSVM. RESULTS Only the NwSVM-based regression enabled estimation of the dynamics of all blood cell types with high accuracy (mean r2 = 0.81). The mean timing of nadir arrival estimated using this regression was 35 days for platelets, 41 days for RBCs, 52 days for lymphocytes, 57 days for WBCs, and 62 days for neutrophils. CONCLUSION The NwSVM can be used to predict myelosuppression and clearly depicts nadir timing differences between platelets and other blood cells.

Abstract
Glioblastoma (GBM) still carries a poor prognosis due to the refractoriness against antitumor drugs. Temozolomide (TMZ), one of the few standard therapy drugs against GBM worldwide, has only limited effect due to acquired TMZ resistance of GBM. Therefore, development of novel therapeutic methods to overcome the TMZ resistance of GBM is urgent. The brain is the most cholesterol-rich organ in the human body, so modulation of cholesterol in tumor cells originating from the brain including GBM may be a tumor-specific therapeutic strategy including enhancement of TMZ effects. The unique lipid metabolism of glioma has recently been reported, but the involvement of intracellular cholesterol in TMZ therapy is yet to be fully elucidated. This review summarizes the effect of modulation of intracellular cholesterol level on cancer therapy including GBM treatment and the implications for TMZ therapy. Our recent findings about the involvement of intracellular cholesterol in TMZ-induced GBM cell death are described.

Abstract
Purpose This study explored the superiority of temozolomide (TMZ) + interferonβ (IFNβ) to standard TMZ as treatment for newly diagnosed glioblastoma (GBM) via randomized phase II screening design. Experimental design Eligibility criteria included histologically proven GBM, with 50% of the tumor located in supratentorial areas, without involvement of the optic, olfactory nerves, and pituitary gland and without multiple lesions and dissemination. Patients in the TMZ + radiotherapy (RT) arm received RT (2.0 Gy/fr/day, 30 fr) with TMZ (75 mg/m2, daily) followed by TMZ maintenance (100–200 mg/m2/day, days 1–5, every 4 weeks) for 2 years. Patients in the TMZ + IFNβ + RT arm intravenously received IFNβ (3 MU/body, alternative days during RT and day 1, every 4 weeks during maintenance period) and TMZ + RT. The primary endpoint was overall survival (OS). The planned sample size was 120 (one-sided alpha 0.2; power 0.8). Results Between Apr 2010 and Jan 2012, 122 patients were randomized. The median OS with TMZ + RT and TMZ + IFNβ + RT was 20.3 and 24.0 months (HR 1.00, 95% CI 0.65–1.55; one-sided log rank P = 0.51). The median progression-free survival times were 10.1 and 8.5 months (HR 1.25, 95% CI 0.85–1.84). The incidence of neutropenia with the TMZ + RT and the TMZ + IFNβ + RT (grade 3–4, CTCAE version 3.0) was 12.7 versus 20.7% during concomitant period and was 3.6 versus 9.3% during maintenance period. The incidence of lymphopenia was 54.0 versus 63.8% and 34.5 versus 41.9%. Conclusions TMZ + IFNβ + RT is not considered as a candidate for the following phase III trial, and TMZ + RT remained to be a most promising treatment. This trial was registered with the UMIN Clinical Trials Registry: UMIN000003466.

Abstract
As a novel target for breast cancer, interferon inducers have found its role as anti-angiogenic agents with diethylaminoethyl dextran (DEAE-Dextran) being a molecule used for centuries as a transfection agent. Our results herein offer an explanation for the emergence of DEAE-Dextran as an anti-tumor agent for TNBC with in-depth mechanistic approach as an anti-angiogenic molecule. DEAE-Dextran has found to possess cytotoxic activity demonstrated during the various in vitro cytotoxicity assays; moreover, as an anti-oxidant, DEAE-Dextran has shown to possess excellent reactive oxygen species scavenging activity. The interferon inducing capacity of DEAE-Dextran was determined qualitatively as well as quantitatively specifically demonstrating overexpression of β-interferon. As a measure of anti-proliferative activity, DEAE-Dextran exhibited reduced ki67, p53, and PCNA levels. Also, overexpression of CK5/6 and p63 in DEAE-Dextran treated animals indicated improvement in breast cell morphology along with an improvement in cell–cell adhesion by virtue of upregulation of β-catenin and E-cadherin. Anti-angiogenic property of DEAE-Dextran was concluded by the downregulation of CD31, VEGF, and NOTCH1 both in vivo and in vitro. Further, apoptosis due to DEAE-Dextran, initially determined by downregulation of Bcl2, was confirmed with flow cytometry. Overall, results are defensive of DEAE-Dextran as an emerging anti-tumor agent with mechanisms pertaining to β-interferon induction with probable VEGF and NOTCH1 inhibition as well as apoptosis which still needs to be studied in further depth.

Abstract
Glioblastomas (GBM) are largely incurable as they diffusely infiltrate adjacent brain tissues and are difficult to diagnose at early stages. Biomarkers derived from serum, which can be obtained by minimally invasive procedures, may help in early diagnosis, prognosis and treatment monitoring. To develop a serum cytokine signature, we profiled 48 cytokines in sera derived from normal healthy individuals (n = 26) and different grades of glioma patients (n = 194). We divided the normal and grade IV glioma/GBM serum samples randomly into equal sized training and test sets. In the training set, the Prediction Analysis for Microarrays (PAM) identified a panel of 18 cytokines that could discriminate GBM sera from normal sera with maximum accuracy (95.40%) and minimum error (4.60%). The 18-cytokine signature obtained in the training set discriminated GBM sera from normal sera in the test set as well (accuracy 96.55%; error 3.45%). Interestingly, the 18-cytokine signature also differentiated grade II/Diffuse Astrocytoma (DA) and grade III/Anaplastic Astrocytoma (AA) sera from normal sera very efficiently (DA vs. normal–accuracy 96.00%, error 4.00%; AA vs. normal–accuracy 95.83%, error 4.17%). Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis using 18 cytokines resulted in the enrichment of two pathways, cytokine-cytokine receptor interaction and JAK-STAT pathways with high significance. Thus our study identified an 18-cytokine signature for distinguishing glioma sera from normal healthy individual sera and also demonstrated the importance of their differential abundance in glioma biology.

Abstract
Cisplatin is one of the most commonly used chemotherapeutic agents for breast cancer treatment. However, its efficacy is greatly limited by its toxic side effects. The present study investigated the synergistic effect of interferon β with cisplatin on MDA MB231 cells. The antiproliferative effect was measured by the 3-(4,5 dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The combination index (CI) was calculated using the method of Chou and Talalay. Cytotoxicity was determined by trypan blue and clonogenic assay. Genotoxic and cytostatic effects were studied using micronucleus assay and nuclear division index (NDI). Protein expression was analyzed using immunoblotting. Interferon β (100-2500 IU/mL) and Cisplatin (0.01-100 μM) had an inhibitory effect on the proliferation of cancer cells in a dose-dependent manner, with the IC50 values at 1500 IU/mL and 20 μM for interferon β and cisplatin, respectively. Western blot analysis revealed expression of interferon β binding receptor in MDA MB231 cells. More interestingly, synergistic, cytotoxic and genotoxic effects were observed after treatment with a combination of interferon β with reduced dosage of cisplatin. Decreased expression of Bcl-2 and increased expression of Bax stimulated the cytochrome c release, which triggers caspase-9 and -3 activation significantly increased in the combinational group. In conclusion the combination of interferon β with reduced dose of cisplatin results synergistically improved growth-inhibition and apoptosis-inducing effect on MDA MB231 cells.

Abstract
OBJECTIVES Methylation of O(6)-methylguanine-DNA methyltransferase (MGMT) has been reported to be a good prognostic factor for patients with glioblastoma multiforme (GBM). To determine whether the absolute value of MGMT messenger RNA (mRNA) might be a prognostic factor and useful for predicting the therapeutic effectiveness of temozolomide, especially with regard to GBMs, the authors measured the absolute value of MGMT mRNA in gliomas by using real-time reverse-transcription polymerase chain reaction (RT-PCR). METHODS MGMT mRNA was measured in 140 newly diagnosed gliomas by real-time RT-PCR using the Taq-Man probe. Among 73 GBMs, 45 had been initially treated with temozolomide and radiation. RESULTS The mean MGMT mRNA value was significantly lower in oligodendroglial tumors than in other tumors. In the 73 GBMs, a significant prognostic factor for progression-free survival was fewer than 1000 copies/ μgRNA of MGMT mRNA (p = 0.0150). Of 45 patients with GBMs that had been treated with temozolomide and radiation, progression-free survival was significantly longer for those whose GMB had fewer than 1000 copies/μgRNA of MGMT mRNA than for those whose GBM had more than 1000 copies/μgRNA (p = 0.0090). In 32 patients with GBMs treated by temozolomide and radiation whose age was younger than 75 years and whose Karnofsky Performance Scale score was more than 70, progression-free and overall survival times were longer for those with GBMs of fewer than 5000 copies/μgRNA of MGMT mRNA than for those with GBMs of more than 5000 copies/μgRNA (p = 0.0365 and p = 0.0312). CONCLUSIONS MGMT mRNA might be useful as a prognostic factor and for predicting the results of therapy for GBMs treated by temozolomide. New individual adjuvant therapy based on the results of MGMT mRNA quantitation has been proposed.

Abstract
Interferon-beta (IFN-β) is reported to augment anti-tumor effects by temozolomide in glioblastoma via down-regulation of MGMT. Promyelocytic leukemia (PML), a gene induced by IFN-β, is a tumor suppressor. Here, we report for the first time that in combination therapy, an IFN-β-induced increase in endogenous PML contributes to anti-tumor effects in p53 wild- and mutant glioma cells in a xenograft mice model. The increased PML promoted the accumulation of p73, a structural and functional homolog of p53, to fuse the coactivator Yes-associated-protein in the PML nuclear bodies. The adjuvant therapy targeted at PML may be a promising therapeutic strategy for glioblastoma.

Abstract
Since the first patients underwent intracranial tumor removal with the radicality control of intraoperative MRI (ioMRI) in September 2005 in our department, the majority of operations performed in the ioMRI room have been indicated for high grade gliomas. In order to elucidate the role of ioMRI scanning in patients harboring high-grade gliomas (HGG) on their survival, one hundred ninety three patients with gliomas WHO grades III and IV were operated either in a standard microsurgical neuronavigated fashion or using additionally ioMRI and were included in a follow-up study. The series started with surgeries from September 2005 until October 2007. Patient attribution to the two groups was based on the logistical availability of the ioMRI on a scheduled surgery day, and on the assumed "difficulty" of the surgery based on the location of the glioma in or near to an eloquent area. Surgery was intended to be as radical as possible without reduction of quality of life. First surgery was performed in 103 patients (75 WHO IV and 28 WHO III) and will be the main topic of this paper. In 60 patients, ioMRI was used, while in 43 patients standard microsurgical neuronavigated resection techniques were applied. Patients were followed in regular intervals mostly until death. Statistical analysis showed a median survival time for patients in whom ioMRI had been used of 20, 37 months compared to 10, 3 months in the cohort who had undergone conventional microsurgical removal. Major influencing concomitants were WHO grades and age which were balanced in both groups.

Abstract
Irinotecan (CPT-11) has shown emerging promise in the treatment of malignant gliomas. It is believed the mechanism of action of irinotecan is to sensitize glioma cells to the cytotoxic action of radiation therapy and alkylating agents. However, clinical trials using weekly or three-weekly doses of CPT-11 have demonstrated imaging responses in only 10-15% of patients. In this study, we evaluated another mechanism of action, angiosuppression by CPT-11 of ACNU-resistant gliomas, using a metronomic administration schedule. Two different types of treatment, (1) conventional and (2) metronomic, were applied to the subcutaneous U87 model. We found that metronomic administration of CPT-11 significantly inhibited malignant glioma growth by inhibiting angiogenesis; this treatment procedure reduced the number of tumor vessels and the area of hypoxic lesions and reduced expression of VEGF and HIF-1alpha, the most important angiogenic factors in gliomas. Metronomic treatment was superior to conventional treatment with regard to the severe systemic side effect of body weight loss. The growth inhibitory effect was very similar for both low and high doses of CPT-11. These angiosuppressive effects of CPT-11 show promise for another use of CPT-11 in metronomic and scheduled angiosuppressive chemotherapy with low dose and long-term administration for malignant gliomas without systemic side effects.

Abstract
BACKGROUND Because of the poor outcomes for patients with recurrent glioblastoma multiforme (GBM), and some laboratory and clinical evidence of efficacy using interferon in GBM, we assessed the toxicity and efficacy of temozolomide (TMZ) combined with either short-acting (IFN) or long-acting (pegylated) interferon alpha2b (PEG) in two single-arm phase II studies, and compared the results to 6-month progression-free survival (PFS-6) data from historical controls. METHODS Two single-arm phase II studies were carried out in adults with GBM. Patients were treated with the standard regimen of TMZ (150-200 mg m(-2) per day x 5 days every month) combined with either 4 million units per m(2) subcutaneously (SQ) three times weekly of IFN or 0.5 microg kg(-1) SQ weekly of PEG. Physical exams and imaging evaluations were carried out every 8 weeks. RESULTS On the IFN study, 34 adults (74% men) were enrolled, and 29 adults (55% men) on the PEG study; median Karnofsky performance status was 80 and 90 for the IFN and PEG studies, respectively. Grade 3 or 4 toxicities were common, leucopoenia and thrombocytopoenia occurring in 35-38% and 18-21% of patients, respectively. Grade 3 or 4 fatigue occurred in 18% of patients on both studies. Lymphopoenia was infrequent. PFS-6 was 31% for 29 evaluable patients in the IFN study and 38% for 26 evaluable patients in the PEG study. CONCLUSION In recurrent GBM patients, both studies of standard dose TMZ with either IFN or PEG showed improved efficacy when compared to historical controls, or reports using TMZ alone. Even though the TMZ+PEG study met criteria for further study, the results of both of these studies must be considered in light of the standard of care (TMZ plus radiotherapy) for newly diagnosed GBM, which has evolved since the inception of these studies. Despite the results of the current studies being eclipsed by the new GBM standard of care, these results can still inform the development of newer approaches for GBM, either in an earlier, upfront setting, or by extrapolation of the results and consideration of the use of PEG or IFN in conjunction with other antiglioma strategies.

Abstract
A 3-chip CCD imaging system has been developed for quantitative in vivo fluorescence imaging. This incorporates a ratiometric algorithm to correct for the effects of tissue optical absorption and scattering, imaging “geometry” and tissue autofluorescence background. The performance was characterized, and the algorithm was validated in tissue-simulating optical phantoms for quantitative measurement of the fluorescent molecule protoporphyrin IX (PpIX). The technical feasibility to use this system for fluorescence-guided surgical resection of malignant brain tumor tissue was assessed in an animal model in which PpIX was induced exogenously in the tumor cells by systemic administration of aminolevulinic acid (ALA).

Abstract
Glioblastoma multiforme (GBM) are among the most devastating neoplasms claiming the lives of patients within a median of 1 year after diagnosis. Treatment of GBM requires a multidisciplinary approach. Treatments include surgery, radiotherapy, chemotherapy and so on. Temozolomide (TMZ) has emerged as an active agent against malignant gliomas. On the basis of the work by the European Organisation for Research and Treatment of Cancer/National Cancer Institute of Canada, concurrent radiotherapy and the oral alkylating agent TMZ followed by adjuvant TMZ has become the standard of care for patients with newly diagnosed GBM, although the methylation status of the O(6)-mehylguanine-DNA methyltransferase promoter is predictive for survival of GBM patients. Gliadel is a biodegradable polymer wafer impregnated with carmustine. Gliadel has been one of the few treatment modalities to demonstrate a statistical benefit in patients with malignant glioma. These new FDA approved drugs advanced the treatment of malignant glioma, but more progress is needed. Patients require improvements in chemotherapy, surgery, radiotherapy, molecular targeted therapy, immunotoxin using the convection-enhanced delivery and more.

Abstract
OBJECT This Phase II study was performed to determine the safety, tolerability, and efficacy of combining nimustine (ACNU)-carboplatin-vincristine-Interferon-beta (IFNbeta) chemotherapy. METHODS Ninety-seven patients with Karnofsky Performance Scale scores of 50 or greater were enrolled in the study. Nimustine (60 mg/m2), carboplatin (110 mg/m2), vincristine (0.6 mg/m2), and IFNbeta (10 microg) were administered on Day 1 concomitant with radiotherapy (63 Gy); vincristine (0.6 mg/m2) and IFNbeta (10 microg) on Days 8 and 15; and IFNbeta alone (10 microg) three times per week throughout the course of radiotherapy. Fifty-six days after radiotherapy ended, the time schedule for chemotherapy was reset and ACNU, carboplatin, vincristine, and IFNbeta were again administered on the new Day 1 and vincristine and IFNbeta on the new Days 8 and 15. This course was repeated every 56 days. Instances of nonhematological toxicity were rare and mild. During the course of radiotherapy, the percentages of patients who experienced Grade 3 toxicity were 14% with neurocytopenia and 7% with thrombocytopenia. Seven percent of all adjuvant chemotherapy cycles following radiotherapy were associated with Grade 3 toxicity, as manifested in neurocytopenia or thrombocytopenia. No instance of Grade 4 toxicity was observed. The median duration of progression-free survival was 10 months (95% confidence interval [CI] 8-12 months) and the median duration of overall survival was 16 months (95% CI 13-20 months). CONCLUSIONS The combination of ACNU-carboplatin-vincristine-IFNbeta chemotherapy and radiotherapy is safe and well tolerated, and may prolong survival in patients with glioblastoma multiforme.

Abstract
1. O6-methylguanine-DNA methyltransferase (MGMT) mRNA was measured in 50 malignant gliomas that had received 1-(4-amino-2-methyl-5-pyrimidynyl) methyl-3-(2-chloroethyl)-3-nitrosourea hydrochloride (ACNU) after the resection of the tumor by real-time reverse transcription-polymerase chain reaction (RT-PCR) using TaqMan probe. 2. The mean absolute value of MGMTmRNA normalized to the level of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) for 50 tumors was 1.29 x 10(4)+/- 1.28 x 10(4) copy/microg RNA (mean +/- SD). The amount of MGMTmRNA less than 6 x 10(3) copy/microg RNA was the most significant factor in predicting the initial effect of treatment with ACNU by multi-variant regression analysis (p = 0.0157). 3. These results suggest that quantitation of MGMTmRNA is the excellent method for predicting for the effect of ACNU in glioma therapy.

Abstract
The prognosis of malignant gliomas remains dismal and alternative therapeutic strategies are required. Immunotherapy with dendritic cells (DCs) pulsed with tumour antigens emerges as a promising approach. Many parameters influence the efficacy of DC-based vaccines and need to be optimised in preclinical models. The present study compares different vaccine schedules using DCs loaded with tumour cell lysate (DC-Lysate) for increasing long-term survival in the GL26 orthotopic murine glioma model, focusing on the number of injections and an optimal way to recall antitumour immune response. Double vaccination with DC-Lysate strongly prolonged median survival compared to unvaccinated animals (mean survival 87.5 days vs. 25 days; p < 0.0001). In vitro data showed specific cytotoxic activity against GL26. However, late tumour relapses frequently occurred after 3 months and only 20% of mice were finally cured at 7 months. While one, two or three DC injections gave identical survival, a boost using only tumour lysate after initial DC-Lysate priming dramatically improved long-term survival in vaccinated mice, compared to the double DC-Lysate group, with 67.5% of animals cured at 7 months (p < 0.0001). In vitro data showed better specific CTL response and also the induction of specific anti-GL26 antibodies in the DC-Lysate/Lysate group, which mediated Complement Dependent Cytotoxicity. These experimental data may be of importance for the design of clinical trials that currently use multiple DC injections.

Abstract
Object
The goal of this study was to assess the impact of neuronavigation on the cytoreductive treatment of solitary contrast-enhancing intracerebral tumors and outcomes of this treatment in cases in which neuronavigation was preoperatively judged to be redundant.
Methods
The authors conducted a prospective randomized study in which 45 patients, each harboring a solitary contrast-enhancing intracerebral tumor, were randomized for surgery with or without neuronavigation. Peri- and postoperative parameters under investigation included the following: duration of the procedure; surgeon’s estimate of the usefulness of neuronavigation; quantification of the extent of resection, determined using magnetic resonance imaging; and the postoperative course, as evaluated by neurological examinations, the patient’s quality-of-life self-assessment, application of the Barthel index and the Karnofsky Performance Scale score, and the patient’s time of death.
The mean amount of residual tumor tissue was 28.9% for standard surgery (SS) and 13.8% for surgery involving neuronavigation (SN). The corresponding mean amounts of residual contrast-enhancing tumor tissue were 29.2 and 24.4%, respectively. These differences were not significant. Gross-total removal (GTR) was achieved in five patients who underwent SS and in three who underwent SN. Median survival was significantly shorter in the SN group (5.6 months compared with 9 months, unadjusted hazard ratio = 1.6); however, this difference may be attributable to the coincidental early death of three patients in the SN group. No discernible important effect on the patients’ 3-month postoperative course was identified.
Conclusions
There is no rationale for the routine use of neuronavigation to improve the extent of tumor resection and prognosis in patients harboring a solitary enhancing intracerebral lesion when neuronavigation is not already deemed advantageous because of the size or location of the lesion.

Abstract
Treatment of malignant glioma requires a multidisciplinary team. Treatment includes surgery, radiotherapy, and chemotherapy. Recently developed agents have demonstrated activity against recurrent malignant glioma and efficacy if given concurrently with radiotherapy in the upfront setting. Oligodendroglioma with 1p/19q deletions has been recognized as a distinct pathologic entity with particular sensitivity to radiotherapy and chemotherapy. Randomized trials have shown that early neoadjuvant or adjuvant administration of procarbazine, lomustine, and vincristine chemotherapy prolongs disease-free survival; however, it has no impact on overall survival. Temozolomide, a novel alkylating agent, has shown modest activity against recurrent glioma. In combination with radiotherapy in newly diagnosed patients with glioblastoma, temozolomide significantly prolongs survival. Molecular studies have demonstrated that the benefit is mainly observed in patients whose tumors have a methylated methylguanine methyltransferase gene promoter and are thus unable to repair some of the chemotherapy-induced DNA damage. For lower-grade glioma, the use of chemotherapy remains limited to recurrent disease, and first-line administration is the subject of ongoing clinical trials. Irinotecan and agents like gefitinib, erlotinib, and imatinib targeting the epidermal growth factor receptor and platelet-derived growth factor receptor have shown some promise in recurrent malignant glioma. This review summarizes recent developments, focusing on the clinical management of patients in daily neuro-oncology practice.

Susceptibility to exogenously added interferon-beta protein depends on intracellular interferon-beta mRNA level in human glioma cells. Cytokine 2005; 32:240-5.

Abstract
Exogenously added human interferon-beta (HuIFN-beta) protein possesses a remarkable antiproliferative activity in human glioma and melanoma. Endogenous HuIFN-beta protein, which is produced by its gene transfer using cationic liposomes, has much more effective antiproliferative activity against these tumors, even in cells resistant to exogenously added HuIFN-beta protein. As the first step to elucidate the possible difference in antiproliferative mechanisms between exogenous and endogenous HuIFN-beta protein, we here investigated the relationship between the intracellular level of its mRNA and susceptibility to exogenously added HuIFN-beta protein. In this study, we used seven human glioma cell lines (SK-MG-1, SK-MG-4, SK-AO2, U87MG, U251SP, U251MG and T98) and one human melanoma cell line (MMAN). At first, we examined the relationship between spontaneous expression of HuIFN-beta mRNA and susceptibility to exogenously added HuIFN-beta protein (50 IU/ml) in human glioma cells and then confirmed a significant correlation between them. Next, we confirmed that administration of 0-100 IU/ml exogenously added HuIFN-beta protein upregulated the HuIFN-beta mRNA in a dose-dependent manner using the RT-PCR technique and that the HuIFN-beta mRNA was suppressed by siRNA for HuIFN-beta in SK-MG-1 and MMAN cells. Furthermore, we confirmed that the siRNA for HuIFN-beta significantly suppressed the antiproliferative effect of SK-MG-1 cells treated with 10-100 IU/ml HuIFN-beta protein and MMAN cells with 25 and 50 IU/ml HuIFN-beta protein. We found this phenomenon in another human glioma cell line, U87MG cells, as well. This finding would suggest that susceptibility to exogenously added HuIFN-beta protein is related to the amount of intracellular HuIFN-beta mRNA in human glioma and melanoma cells.

Abstract
The precise mechanisms governing the direct effect of IFN-beta, including apoptosis induction, are not yet fully understood. To gain a better insight into these mechanisms, we investigated the signaling pathways focusing particularly on interferon regulatory factor 1 (IRF-1) and IRF-2 in glioblastoma cell lines. Furthermore, we attempted to determine whether or not IRF-1 and IRF-2 act as additional prognostic indicators in diffusely infiltrating astrocytomas (DIA). We first assessed the cytotoxic effects of IFN-beta based on a cell growth study and modified MTT assay, and then quantified the apoptosis using a sandwich enzyme immunoassay following IFN-beta treatment in the cell lines, U-87MG, T98G, and A-172. Subsequently, we carried out an analysis of apoptosis-related molecules as evaluated by densitometric analysis of Western blots, focusing on IRF-1 and IRF-2, and two major initiator caspases, caspase-8 and caspase-9. Furthermore, we assessed the expression of type I IFN receptor, IRF-1, and IRF-2 using immunohistochemical techniques in 63 DIA (15 of WHO grade II, 18 of grade III, and 30 of grade IV), and analyzed their impact on prognosis. An increase in apoptosis was apparent after 48 h of IFN-beta treatment (1 x 10(4) IU/ml) in T98G but not in U-87MG or A-172. IFN-beta treatment for 6 h significantly enhanced the expression of IRF-1 in all three cell lines. However, an enhanced expression of IRF-2 was observed only in the not-most-sensitive, non-apoptosis-induced U-87MG and A-172. While minimal processing of caspase-8 was noted in the three cell lines throughout the experiment, caspase-9 activation was observed in the apoptosis-detected T98G after 48 h of treatment, as indicated by a 1.33-fold increase (P=0.037). On the other hand, the IRF-1 LI and IRF-1/IRF-2 LI ratio were greater in low-grade DAI, and were negatively correlated with the histopathological grade in DIA (P=0.017 and P=0.001, respectively). Furthermore, the IRF-1/IRF-2 LI ratio was negatively correlated with the MIB-1 LI in DIA (P=0.004), and represented an independent and most powerful determinant of overall survival compared to other conventional prognostic factors (P=0.018). However, the relation was not statistically significant when only patients with high-grade DIA were assessed. Our findings suggest that up-regulation of IRF-1 and IRF-2 might be an important determinant of susceptibility to IFN-beta mediated cytotoxicity including apoptosis. Furthermore, the IRF-1/IRF-2 LI ratio may reflect the proliferative state of DIA and constitute an important prognostic marker in DIA. Thus, IRF-1 and IRF-2 could represent one of the therapeutic target sites for the regulation of cell growth in DIA.

Abstract
Previous investigators have reported encouraging results for malignant gliomas treated using a combination of human interferon beta (IFN-beta) with nimustine hydrochloride (ACNU) and radiation therapy (termed IAR therapy). This study was undertaken to examine further the efficacy of the IAR regimen followed by maintenance therapy with IFN-beta and ACNU in patients with newly diagnosed malignant astrocytomas. Fifty-eight patients were enrolled onto the trial. IFN-beta (2 x 10(6) IU/m(2)/day x 5 days/week for 8 consecutive weeks) and ACNU (80 mg/m(2) on days 1 and 36) were administered intravenously concomitant with radiation therapy followed by IFN-beta (every 2 weeks) and ACNU (every 6 weeks). Of 33 patients assessable for a response, 11 responded (33%), with 4 complete responses. The estimated median overall survival (OS) was 16 months, with values of 58 and 13 months for anaplastic astrocytoma (AA) and glioblastoma (GB) patients, respectively. The overall progression free survival (PFS) was 11 months, with values of 31 and 7 months for AA and GB patients, respectively. The IAR therapy was safe and well tolerated. Based on a statistical analysis of the factors that affected the PFS and OS, histologic grade, postoperative Karnofsky performance scale (KPS), and extent of surgery were identified as independent predictors. The postoperative KPS stood out as the most powerful prognostic factor, which was also the best predictor for the response to IAR therapy. Our findings suggest a possible benefit for IAR therapy followed by maintenance therapy mainly in AA. In addition, they emphasize the importance of a preserved KPS after cytoreductive surgery, which could produce a potential benefit for adjuvant therapy and could ultimately lead to a prolonged survival.

Abstract
BACKGROUND AND OBJECTIVES Fluorescence image-guided brain tumor resection is thought to assist neurosurgeons by visualizing those tumor margins that merge imperceptibly into normal brain tissue and, hence, are difficult to identify. We compared resection completeness and residual tumor, determined by histopathology, after white light resection (WLR) using an operating microscope versus additional fluorescence guided resection (FGR). STUDY DESIGN/MATERIALS AND METHODS We employed an intracranial VX2 tumor in a preclinical rabbit model and a fluorescence imaging/spectroscopy system, exciting and detecting the fluorescence of protoporphyrin IX (PpIX) induced endogenously by administering 5-aminolevulinic acid (ALA) at 4 hours before surgery. RESULTS Using FGR in addition to WLR significantly increased resection completeness by a factor 1.4 from 68+/-38 to 98+/-3.5%, and decreased the amount of residual tumor post-resection by a factor 16 from 32+/-38 to 2.0+/-3.5% of the initial tumor volume. CONCLUSIONS Additional FGR increased completeness of resection and enabled more consistent resections between cases.

Abstract
We examined whole genomic aberrations of biopsied samples from 19 independent glioblastomas by array-based comparative genomic hybridization analysis. The highest frequencies of copy number gains were observed on RFC2 (73.3%), EGFR (63.2%), and FGR, ELN, CDKN1C , FES, TOP2A, and ARSA (57.9% each). The highest frequencies of copy number losses were detected on TBR1 (52.6%), BMI1 (52.6%), EGR2 (47.4%), DMBT1 (47.4%), MTAP (42.1%), and FGFR2 (42.1%). The copy number gains of CDKN1C and INS and the copy number losses of TBR1 were significantly correlated with longer survival of patients. High-level amplifications were identified on EGFR, SAS/CDK4, PDGFRA, MDM2, and ARSA. These genes are assumed to be involved in tumorigenesis or progression of glioblastomas. The first attempts to apply detrended fluctuation analysis to copy number profiles by considering the reading direction as the time axis demonstrated that higher long-term fractal scaling exponents (alpha2) correlated well with longer survival of glioblastoma patients. The present study indicates that array-based comparative genomic hybridization analysis has great potential for assessment of copy number changes and altered chromosomal regions of brain tumors. Furthermore, we show that nonlinear analysis methods of whole genome copy number profiles may provide prognostic information about glioblastoma patients.

Abstract
Reflections directly involving the ongoing, intense research activities in biology, the neurosciences and in neurosurgery are discussed including the evolving diagnostic and treatment modalities of primary and secondary malignant gliomas of the central nervous system. The etiology of this enigmatic disease remains obscure, and a curative therapy is still not available. Nevertheless, as a result of changing paradigms in neuroanatomy, neuropathology, neurophysiology, neuroradiology and in neurosurgery, and taking into account the broader selection of adjuvant therapies available, well circumscribed malignant gliomas, which are in predilected compartments of the brain, can be efficiently resected. Good life quality and a respectable survival time are achieved in the majority of patients.

Abstract
Angiogenesis is crucial to the growth of malignant gliomas. Therefore, antiangiogenic therapy represents a new, promising therapeutic modality for malignant gliomas. This study was designed to define the malignant glioma cases most suitable for antiangiogenic therapy in humans and to demonstrate the efficacy of antiangiogenic therapy in animals. Protein expression of the most potent angiogenic factor, vascular endothelial growth factor (VEGF), and its specific natural inhibitor, soluble Flt-1, as well as vessel architecture, including vessel density, area, and diameter, was evaluated in human malignant glioma samples (24 glioblastomas, 13 anaplastic astrocytomas). Among these, VEGF >1000ng/ml, VEGF/soluble Fltl ratio >1, vessel density >30, and vessel area >7% were prognostic factors for malignant gliomas. Based on these results, we performed three different antiangiogenic experiments targeted to inhibit VEGF expression in a human malignant glioma (U87) mouse model: anti-VEGF neutralized antibody intraperitoneal injection; interferon-beta intramusclar injection; and transfection of an endogenous nonspecific angiogenesis inhibitor, thrombospondin-1, into glioma cells caused inhibition of VEGF secretion and/or mRNA expression and resulted in glioma growth inhibition of 70%, 84%, and 50%, respectively, compared with control. We conclude that malignant gliomas with high degrees of VEGF expression and vessel areas are good candidates for antiangiogenic therapy, especially that designed to inhibit VEGF expression.

Abstract
Transfer of interferon beta gene via cationic liposomes has been found to induce regression of experimental glioma. We performed a pilot clinical trial of safety and effectiveness of this interferon beta gene therapy in five patients with malignant glioma (glioblastoma multiforme or anaplastic astrocytoma). Transgene expression and antitumor activity were detected in four patients. Two patients showed a partial response (>50% tumor reduction) and two others had stable disease 10 weeks after beginning therapy. One patient could not be evaluated because of previous treatment with gamma-knife therapy. This study suggests the feasibility and safety of interferon beta gene therapy, which may become an important treatment option for patients with malignant glioma.

Abstract
The authors have recently performed a fluorescence-guided tumor resection procedure by using high-dose fluorescein sodium without any special surgical microscopes for the intraoperative visualization of glioblastoma multiforme (GBM), and they report on the actual procedure and clinicopathological findings. Thirty-two patients with GBMs underwent tumor resection during which this fluorescence-guided procedure was used. Fluorescein sodium (20 mg/kg) was intravenously injected after dural opening at the craniotomy site. The tumor was stained almost homogeneously yellow and the color was intense enough to be readily perceived for resection. The center of the solid lesion was stained a deep yellow and surrounded by a transition zone that was faintly stained. The colored lesion was clearly distinguishable from the unstained zone outside the GBM, particularly in the white matter. Both the deeply and faintly stained regions included endothelial proliferation and dense tumor cells. In the unstained region, less dense tumor cells were consistently revealed; however, no endothelial proliferation could be seen. Gross-total resection (GTR) was successful in 84.4% of the patients who received an injection of fluorescein sodium, which accounted for 100% of those in whom all the visible yellow color (both the deeply and faintly stained regions) was judged to have been resected during operation. Gross-total resection was performed in 100% of the patients who underwent the fluorescence-guided procedure and assigned to Stage I, a GBM stage in which, as a therapeutic policy, the tumor should be resected as radically as possible. The GTR rates in patients who received fluorescein sodium were significantly higher than those in patients who did not (73 patients with GBMs who underwent tumor resection without the fluorescence-guided procedure). Although the extent of surgery was revealed to be one of the significant and independent prognostic factors for GBM, the fluorescein sodium-guided resection procedure was not a significant or independent prognostic factor in this series. This surgical procedure does not require any special surgical microscopic equipment and is simple, safe, useful, readily accomplished, and universally available for resection of GBMs. Its efficacy simplifies the surgical procedure of navigating the stained lesion from the unstained area to achieve GTR of GBMs, which can be demonstrated on magnetic resonance images.

Abstract
As type I interferons (IFNs) enhance the stimulatory activity of dendritic cells (DCs), we hypothesized that transfection of glioma cells with the IFN-beta gene in the presence of DCs would provide particularly effective antitumor activity by both facilitating apoptosis of glioma cells and presenting the resulting glioma antigens to T cell by DCs, thereby inducing specific T-cell responses against glioma cells. A mouse glioma cell line 203G was first transfected with cDNA encoding IFN-beta using cationic liposomes, then cocultured with syngeneic bone marrow-derived DCs and naïve splenic T cells. The 203G cells were almost completely killed following 96-hour coculture with DCs and T cells, and strong tumor-specific cytotoxic T-lymphocyte (CTL) activity accompanied by high level interleukin (IL)-12 and IFN-gamma production was observed in culture. In addition, omission of either IFN-beta gene delivery, DCs or T cells from the coculture completely abrogated the induction of the CTL activity, suggesting that the combination of these components was required to elicit an optimal effect. On the basis of these in vitro data, syngeneic animals bearing subcutaneous 203G tumors received intratumoral injections of IFN-beta gene and DCs. Suppression of the tumor growth by this combinational therapy was superior to treatment with DC or IFN-beta gene solely. This combination may constitute a new therapeutic strategy to induce potent antiglioma immune responses.

Abstract
Hypoxic cells play a key role in the radioresistance of malignant glioma. Interferon-beta, ACNU as nimustine hydrochloride and radiotherapy (IAR) is a common therapy for malignant glioma in Japan. Since hyperbaric oxygenation (HBO) increases oxygen pressure in glioma tissue, we applied a modified IAR therapy, radiotherapy after HBO combined with interferon-beta and ACNU (HBO/IAR therapy), for supratentorial malignant gliomas. Daily radiation therapy was completed within 15 min after HBO. We assessed HBO/IAR with respect to toxicity, response rates and the time of tumor progression (TTP). We also examined the incidence of responses by some prognostic factors before HBO/IAR, namely, age, Karnofsky performance scale (KPS), histological type, tumor size, tumor site and operation type. Of 39 patients who participated in this study, 35 underwent a complete schedule of HBO/IAR therapy in which toxicity was permissible. Thirty patients (76.9%) either maintained or increased KPS during HBO/IAR with a mean duration of 68 +/- 14 days. The response rates (CR + PR%) for glioblastoma, anaplastic astrocytoma and overall were 50%, 30% and 43%, respectively. The incidence of therapeutic responses among all prognostic factors before HBO/IAR did not significantly differ. Median TTP for patients with glioblastoma, patients with anaplastic astrocytoma, and overall were 38, 56 and 43 weeks, respectively. The present study suggested that HBO/IAR therapy could be applied to especially patients with poor prognostic factors, because of its short treatment period, its permissible toxicity and identical response to patients with good prognostic factors.

Abstract
O(6)-methylguanine-DNA methyltransferase (MGMT) mRNA expressions were examined in 100 neuroepithelial tumors by real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR) using SYBR Green I. The mean relative quantitation value of MGMTmRNA normalized to the level of beta2-microglobulin for 100 tumors was 5.3 +/- 11.2. The mean value of 41 glioblastomas was significantly higher than that for the other 59 tumors (p = 0.0008 by Student's t-test). In contrast, the means of 19 low-grade gliomas and 12 medulloblastomas were significantly lower than that of other tumors (p = 0.0282 and p = 0.0456 by Student's t-test). Among the 55 retrospective patients who had been treated with 1-(4-amino-2-methyl-5-pyrimidynyl)methyl-3-(2-chloroethyl)- 3-nitrosourea hydrochloride (ACNU), the value was a significant independent predictor of the effect of initial therapy with ACNU (p = 0.0007 by Mann-Whitney U-test) and the survival period (p = 0.0175 by Wald test). The value >or=1 was the most significant factor in predicting the initial effect of treatment by multi-variant regression analysis (p < 0.0001). These results suggest that our individual adjuvant therapy based on MGMTmRNA expression may be improved by the application of real-time quantitative RT-PCR.

Abstract
Low-grade diffuse astrocytomas are slowly growing tumors with a relatively long overall survival. However, a substantial proportion undergoes dedifferentiation to a more malignant phenotype. Considerable controversy exists as to the best therapeutic management for patients with such tumors. Over the past decade, we have applied human fibroblast interferon (HFIF) therapy without radiation therapy to low-grade astrocytomas. We investigated 28 patients with WHO grade II astrocytomas of the cerebral hemispheres treated by surgery plus HFIF therapy. The overall response rate to the HFIF therapy was 36%. All side-effects of HFIF were transient, tolerable and manageable. The 5-year progression free survival and overall survival probabilities were 65% and 96%, respectively. Although our data from small cohort of patients may have modest value, our results suggest that HFIF may be useful in treating low-grade diffuse astrocytomas.

Abstract
PURPOSE To evaluate the efficacy and toxicity of chemotherapy with ACNU (1-(4-amino-2-methyl-5-pyrimidinyl)-methyl-(2-chloroethyl)-3-nitrosourea) plus cisplatin followed by cranial irradiation in patients with newly diagnosed glioblastoma multiforme. PATIENTS AND METHODS Between August 1999 and July 2001, previously untreated 30 patients with histologically confirmed glioblastoma multiforme were treated. Chemotherapy consisting of up to 2 cycles of 72 h of continuous intravenous infusion of ACNU (40 mg/m2/day) and cisplatin (40 mg/m2/d) was given over a 6-week period. Radiation was begun 6 weeks after the second cycle of chemotherapy. RESULTS Median age was 48 years (range 18-66 years) and 22 patients with residual measurable disease after surgery were eligible for response analysis. One (5%) had a complete response (CR), 36% partial response (PR), 14% stable disease (SD), and 45% progressive disease (PD) after chemotherapy. After additional radiation, 22% had CR, 22% PR, 16% SD, and 42% PD. Grades III and IV leukopenia and thrombocytopenia occurred in 18 cycles (36%) and 15 cycles (30%), respectively. No fatal complications occurred. Median time to progression was 5.9 months (95% CI 5.1-6.8 months) and median overall survival was 14.9 months (95% CI 9.1-20.7 months). CONCLUSIONS Preradiation chemotherapy with ACNU plus cisplatin is effective and feasible in patients with gliobiastoma multiforme.

Abstract
Object.In previous studies interferon-β (IFNβ) has been shown to suppress tumor growth. In this report, the antitumor effect of macrophages stimulated with IFNβ is investigated in murine gliomas in vitro.Methods.The authors examined the cytotoxic activity of IFNβ-stimulated peritoneal macrophages in glioma cells labeled with [3H]thymidine. The addition of IFNβ enhanced cytotoxic activity in gliomas as well as the nitric oxide (NO) production of macrophages in cocultures. Addition of NG-monomethyl-l-arginine (l-NMMA) andl-N6-(1-iminoethyl)-lysine, but notd-NMMA (an inactive analog ofl-NMMA), blocked this cytotoxic activity. The addition of IFNβ had no direct effect on the growth of glioma cells. Because NO was not produced from macrophages treated with IFNβ alone and IFNβ-induced cytotoxic activity did not need cell-to-cell contact, the authors suspected that gliomas produce some soluble factors that act as cofactors for IFNβ-induced cytotoxic activity. Macrophages stimulated with IFNβ in the presence of glioma culture supernatants showed higher cytotoxicity against glioma cells than macrophages stimulated with IFNβ alone. Furthermore, NO was markedly produced by IFNβ-stimulated macrophages in the presence of glial culture supernatants.Conclusions.These data indicate that the antiglioma activity of IFNβ through macrophages is due to NO produced by macrophages and that glioma-derived soluble factors play a role as an essential cofactor in this activity.

Abstract
Overall survival and progression-free survival after 5 and 10 years of 31 patients with malignant glioma treated by a combination of surgery, postoperative radiotherapy, and chemotherapy with a PCV regimen (procarbazine, CCNU [lomustine] and vincristine) is described. Parameters were evaluated by age at diagnosis, gender, ethnic origin, pre- and postsurgery Karnofsky Performance Status (KPS) score, limit and amount of surgical resection, histopathologic type, number of chemotherapy courses, time between surgery and radiotherapy, response to combined therapy, and dosage and type of radiotherapy. Progression-free survival was 29% at 24 months and 22% at 60 and 120 months. Overall survival was 47%, 36%, and 36% after 24, 60, and 120 months, respectively. Favorable prognostic factors for survival in univariate analysis were pre- and postoperative KPS (> or =70; p = 0.015; p = 0.0025, respectively), age of patients (<40; p = 0.01), number of chemotherapy cycles (> or =6; p = 0.02), and radiation dose (> or =60 Gy; p = 0.0015). The only significant prognostic factors for overall survival in a stepwise multivariate analysis were irradiation dose (p = 0.0001), number of chemotherapy cycles (p = 0.001), and preoperative KPS (p = 0.05); for progression-free survival it was number of chemotherapy cycles (p = 0.004). Survival was not affected by excision size, radiation method, histopathologic type of tumor, gender, ethnic origin, or time lapsed between surgery and irradiation.

Abstract
We constructed an adeno-associated virus (AAV) vector containing the human interferon-beta (HuIFN-b ) gene (AAV-IFN-beta) and investigated its antitumor effect against human glioma cells (U251-SP) inoculated into the brain of nude mice. Prior to this, we examined human glioma cells transduced with AAV-IFN-beta using video-enhanced contrast differential interference contrast (VEC-DIC) microscopy. Infection of AAV-IFN-beta induced apoptosis and secondary necrosis in human glioma cells. In in vivo experiments, we confirmed production of HuIFN-beta and induction of heat-shock protein (HSP) in glioma cells transduced with AAV-IFN-beta. Growth of the experimental gliomas was completely inhibited by six injections of AAV-IFN-beta, starting 7 days after transplantation of glioma cells. In addition, the survival of mice treated with AAV-IFN-beta was remarkably prolonged. These results indicate that AAV-IFN-beta induces apoptosis of glioma cells and has a strong antitumor effect in this experimental glioma model.

Abstract
We investigated stereotactic intratumoral microinfusion of nimustine (ACNU) in recurrent brain tumors. Eligibility required histologic confirmation of glioma recurrence despite standard radiotherapy and chemotherapy as well as enhancement of the recurrence with gadolinium on magnetic resonance imaging (MRI). A total intratumoral dose of 10 mg of ACNU was administered continuously with a microinfusion pump over an average of 13h. Fifteen infusions were given in nine patients. All patients completed the treatment safely. On MRI, necrotic changes surrounded the infusion area in all patients, and tumor progression was inhibited or performance score was improved in seven of nine patients. No symptomatic systemic toxicity was evident, although one patient developed permanent left oculomotor palsy locally after treatment of a left medial temporal tumor. It is concluded that direct microinfusion of ACNU into recurrent gliomas can induce tumor necrosis and inhibit tumor growth.

Abstract
The retrospective clinicopathological characteristics of oligodendroglial tumors were investigated in patients who underwent surgery, radiotherapy, and/or chemotherapy. Regarding oligodendroglioma and oligoastrocytoma without malignancy, patients who had undergone radiation therapy at a total dose of 40-50Gy had relatively long postoperative survival. Of these 15 patients, 6 showed signs of recurrence, and after additional treatment, 5 patients are still alive. On the other hand, regarding anaplastic oligodendroglial tumors, patients with anaplastic oligoastrocytoma responded well to combination chemotherapy with interferon beta, nitrosourea derivatives (ACNU/ MCNU), and radiation therapy (referred to as IAR/IMR) and survived longer than patients with anaplastic oligodendroglioma. In conclusion, patients with oligodendroglial tumors could survive longer by treatment involving surgery and radiotherapy. As for malignancy, cases of anaplastic oligoastrocytoma could be effectively treated by adjuvant therapy using IAR/IMR after surgery, but in cases of anaplastic oligodendroglioma, the response to IAR/IMR was not good, and another strategy of treatment should be recommended.

Abstract
New adjuvant therapy individualized by the results of reverse transcription-polymerase chain reaction (RT-PCR) for drug-resistance genes has been used to treat malignant gliomas. Protocol studies for malignant gliomas were not so encouraging in their therapeutic results because of heterogeneity and the various drug-sensitivities of the tumors. Individualization of glioma therapy is recommended. Drug-resistance genes messenger ribonucleic acid (mRNA) expressions were investigated in drug-resistant human glioma cell lines derived from U87MG and 46 frozen samples of retrospectively examined neuroepithelial tumors (12 low grade neuroepithelial tumors, 16 Grade III gliomas, 11 glioblastomas, and 7 other malignant neuroepithelial tumors such as medulloblastomas and primitive neuroectodermal tumors) by RT-PCR with the specific primers for O6-methylguanine DNA methyltransferase (MGMT), multidrug-resistance gene 1 (MDR1), multidrug-resistance-associated protein (MRP), and glutathione-S-transferase-pi (GST-pi). Thirty-seven preliminary individual adjuvant therapies (IAT) based on RT-PCR results, mainly in MGMT expression, were performed on 30 consecutive patients with neuroepithelial tumors. In the retrospectively examined series, the initial response to 1-(4-amino-2-methyl-5-pyrimidynyl) methyl-3-(2-chloroethyl)-3-nitrosourea hydrochloride (ACNU) was correlated most significantly to the MGMT mRNA expression among 11 independent prognostic factors (p = 0.0037) in multivariate logistic regression analysis. In the preliminary IAT, 17 of 32 evaluable therapies had a partial or complete response (53.1% response rate). Our IAT based on RT-PCR seemed to be more effective than conventional therapies for malignant gliomas.
