Abstract
Glioblastomas are the most common malignant brain tumor and despite extensive research have a dismal prognosis. This review focuses on the current treatment paradigms of glioblastoma and highlights current advances in surgical approaches, imaging techniques, molecular diagnostics, and translational efforts. Several promising clinical trials in immunotherapy and personalized medicine are discussed and the importance of quality of life in the patients and their caregivers both during active treatment and survivorship is also commented on.

Abstract
BACKGROUND A growing body of clinical data highlights the prognostic importance of achieving gross total resection (GTR) in patients with glioblastoma. The aim of this study was to determine nationwide practice and attitudes towards achieving GTR and dealing with residual enhancing disease. METHODS The study was in 2 parts: an electronic questionnaire sent to United Kingdom neuro-oncology surgeons to assess surgical practice followed by a 3-month prospective, multicenter observational study of current neurosurgical oncology practice. RESULTS Twenty-seven surgeons representing 22 neurosurgical units completed the questionnaire. Prospective data were collected for 113 patients from 15 neurosurgical units. GTR was deemed to be achieved at time of surgery in 82% (91/111) of cases, but in only 45% (36/80) on postoperative MRI. Residual enhancing disease was deemed operable in 16.3% (13/80) of cases, however, no patient underwent early repeat surgery for residual enhancing disease. The most commonly cited reason (38.5%, 5/13) was perceived lack of clinical benefit. CONCLUSION There is a subset of patients for whom GTR is thought possible, but not achieved at surgery. For these patients, early repeat resection may improve overall survival. Further prospective surgical research is required to better define the prognostic implications of GTR for residual enhancing disease and examine the potential benefit of this early re-intervention.

Abstract
Repeated reports of more than ten years postoperative survival in patients with glioblastoma multiforme (GM) have appeared in the literature over the last decades. Authors have tried to identify the clinical, therapeutic and histological features determining long-term survival. We present two patients in whom, after radical removal of the tumor followed by conventional radiation, there has been no recurrence for at least ten years. The young age of the patients and the radical surgical approach were in accordance with previous reports of long-term survival. Nevertheless, one tumor originated from the thalamus, a location considered to be of unfavorable prognosis. We therefore further discuss the value of clinical signs as determinants in the prognosis of GM.

Abstract
Aims and background The optimum conventional radiotherapy in glioblastoma multiforme patients has not been clearly defined by prospective trials. To better characterize a standard radiotherapy in glioblastoma multiforme, the impact on survival of different fields and doses was analyzed in a retrospective single center series. Methods One hundred and forty-seven patients with glioblastoma multiforme, submitted to biopsy only (n = 15), subtotal (n = 48) or total resection (n = 82) and who completed the planned postsurgical radiotherapy, were considered. The median age was 57 years, the male/female ratio 1.5/1, and the performance status ≥70 in 76%. Whole brain irradiation, followed by a boost to partial brain, was used in 75 cases with a whole brain dose of 44–50 Gy (median, 46) and a partial brain dose of 56–70 Gy (median, 60 Gy). Partial brain irradiation alone was used in 72 patients with a dose of 56–70 Gy (median, 61 Gy). Ninety-eight patients received 56–60 Gy (median, 59 Gy) to partial brain whereas 49 patients received 61–70 Gy (median, 63 Gy). Results There was an almost significantly longer survival in patients irradiated to the partial brain alone with respect to those also receiving whole brain radiotherapy (P = 0.056). Doses <60 Gy significantly prolonged survival (P = 0.006). Multivariate analysis confirmed that the impact on survival of radiation dose was independent of age, performance status, extent of surgery, field of irradiation and the use of chemotherapy. The extent of irradiation field was not independently related to improved survival. Conclusions Our retrospective findings suggest that we reflect on the adequacy of the current standard irradiation parameters. Well-designed prospective trials are necessary to standardize the radiotherapy control group in patients with glioblastoma multiforme to be compared in phase III trials with innovative therapeutic approaches.

Abstract
BACKGROUND Extent of resection (EOR) correlates with glioblastoma outcomes. Resectability and EOR depend on anatomical, clinical, and surgeon factors. Resectability likely influences outcome in and of itself, but an accurate measurement of resectability remains elusive. An understanding of resectability and the factors that influence it may provide a means to control a confounder in clinical trials and provide reference for decision making. OBJECTIVE To provide proof of concept of the use of the collective wisdom of experienced brain tumor surgeons in assessing glioblastoma resectability. METHODS We surveyed 13 academic tumor neurosurgeons nationwide to assess the resectability of newly diagnosed glioblastoma. Participants reviewed 20 cases, including digital imaging and communications in medicine-formatted pre- and postoperative magnetic resonance images and clinical vignettes. The selected cases involved a variety of anatomical locations and a range of EOR. Participants were asked about surgical goal, eg, gross total resection, subtotal resection (STR), or biopsy, and rationale for their decision. We calculated a "resectability index" for each lesion by pooling responses from all 13 surgeons. RESULTS Neurosurgeons' individual surgical goals varied significantly ( P = .015), but the resectability index calculated from the surgeons' pooled responses was strongly correlated with the percentage of contrast-enhancing residual tumor ( R = 0.817, P < .001). The collective STR goal predicted intraoperative decision of intentional STR documented on operative notes ( P < .01) and nonresectable residual ( P < .01), but not resectable residual. CONCLUSION In this pilot study, we demonstrate the feasibility of measuring the resectability of glioblastoma through crowdsourcing. This tool could be used to quantify resectability, a potential confounder in neuro-oncology clinical trials.

Abstract
Glioblastoma (GBM) is a highly aggressive and lethal form of primary brain cancer. Numerous barriers exist to the effective treatment of GBM including the tightly controlled interface between the bloodstream and central nervous system termed the 'neurovascular unit,' a narrow and tortuous tumor extracellular space containing a dense meshwork of proteins and glycosaminoglycans, and genomic heterogeneity and instability. A major goal of GBM therapy is achieving sustained drug delivery to glioma cells while minimizing toxicity to adjacent neurons and glia. Targeted nanotherapeutics have emerged as promising drug delivery systems with the potential to improve pharmacokinetic profiles and therapeutic efficacy. Some of the key cell surface molecules that have been identified as GBM targets include the transferrin receptor, low-density lipoprotein receptor-related protein, αv β3 integrin, glucose transporter(s), glial fibrillary acidic protein, connexin 43, epidermal growth factor receptor (EGFR), EGFR variant III, interleukin-13 receptor α chain variant 2, and fibroblast growth factor-inducible factor 14. However, most targeted therapeutic formulations have yet to demonstrate improved efficacy related to disease progression or survival. Potential limitations to current targeted nanotherapeutics include: (1) adhesive interactions with nontarget structures, (2) low density or prevalence of the target, (3) lack of target specificity, and (4) genetic instability resulting in alterations of either the target itself or its expression level in response to treatment. In this review, we address these potential limitations in the context of the key GBM targets with the goal of advancing the understanding and development of targeted nanotherapeutics for GBM.

Abstract
Although resection remains the mainstay in the treatment of gliomas, microscopically complete resection of most central nervous system tumors remains challenging, and is, in fact, rarely accomplished. Considering their invasive nature, gross total resections to clearly negative margins often do or would require removal or transection of functional brain, with likely serious neurologic deficits. Consequently, radiotherapy has emerged as an indispensable component of therapy. It is delivered primarily by external-beam radiotherapy or brachytherapy techniques. Herein, we present the biologic principles, techniques, and applications of radiotherapy in glioma treatment today.

Abstract
PURPOSE Epilepsy is one of the most common manifestations in gliomas and has a severe effect on the life expectancy and quality of life of patients. The aim of our study was to assess the potential connections between clinicopathological factors and postoperative seizure. METHOD We retrospectively investigated a group of 147 Chinese high-grade glioma (HGG) patients with preoperative seizure to examine the correlation between postoperative seizure and clinicopathological factors and prognosis. Univariate analyses and multivariate logistic regression analyses were performed to identify factors associated with postoperative seizures. Survival function curves were calculated using the Kaplan-Meier method. RESULTS 53 patients (36%) were completely seizure-free (Engel class I), and 94 (64%) experienced a postoperative seizure (Engel classes II, III, and IV). A Chi-squared analysis showed that anaplastic oligodendroglioma/anaplastic oligoastrocytoma (AO/AOA) (P=0.05), epidermal growth factor receptor (EGFR) expression (P=0.0004), O(6)-methylguanine DNA methyltransferase (MGMT) expression (P=0.011), and phosphatase and tensin homolog (PTEN) expression (P=0.045) were all significantly different. A logistic regression analysis showed that MGMT expression (P=0.05), EGFR expression (P=0.001), and AO/AOA (P=0.038) are independent factors of postoperative seizure. Patients with lower MGMT and EGFR expression and AO/AOA showed more frequent instances of postoperative seizure. Postoperative seizure showed no statistical significance on overall survival (OS) and progression-free survival (PFS). CONCLUSION Our study identified clinicopathological factors related to postoperative seizure in HGGs and found two predictive biomarkers of postoperative seizure: MGMT and EGFR. These findings provided insight treatment strategies aimed at prolonging survival and improving quality of life.

Abstract
OBJECT
Awake craniotomy is currently a useful surgical approach to help identify and preserve functional areas during cortical and subcortical tumor resections. Methodologies have evolved over time to maximize patient safety and minimize morbidity using this technique. The goal of this study is to analyze a single surgeon's experience and the evolving methodology of awake language and sensorimotor mapping for glioma surgery.
METHODS
The authors retrospectively studied patients undergoing awake brain tumor surgery between 1986 and 2014. Operations for the initial 248 patients (1986–1997) were completed at the University of Washington, and the subsequent surgeries in 611 patients (1997–2014) were completed at the University of California, San Francisco. Perioperative risk factors and complications were assessed using the latter 611 cases.
RESULTS
The median patient age was 42 years (range 13–84 years). Sixty percent of patients had Karnofsky Performance Status (KPS) scores of 90–100, and 40% had KPS scores less than 80. Fifty-five percent of patients underwent surgery for high-grade gliomas, 42% for low-grade gliomas, 1% for metastatic lesions, and 2% for other lesions (cortical dysplasia, encephalitis, necrosis, abscess, and hemangioma). The majority of patients were in American Society of Anesthesiologists (ASA) Class 1 or 2 (mild systemic disease); however, patients with severe systemic disease were not excluded from awake brain tumor surgery and represented 15% of study participants. Laryngeal mask airway was used in 8 patients (1%) and was most commonly used for large vascular tumors with more than 2 cm of mass effect. The most common sedation regimen was propofol plus remifentanil (54%); however, 42% of patients required an adjustment to the initial sedation regimen before skin incision due to patient intolerance. Mannitol was used in 54% of cases. Twelve percent of patients were active smokers at the time of surgery, which did not impact completion of the intraoperative mapping procedure. Stimulation-induced seizures occurred in 3% of patients and were rapidly terminated with ice-cold Ringer's solution. Preoperative seizure history and tumor location were associated with an increased incidence of stimulation-induced seizures. Mapping was aborted in 3 cases (0.5%) due to intraoperative seizures (2 cases) and patient emotional intolerance (1 case). The overall perioperative complication rate was 10%.
CONCLUSIONS
Based on the current best practice described here and developed from multiple regimens used over a 27-year period, it is concluded that awake brain tumor surgery can be safely performed with extremely low complication and failure rates regardless of ASA classification; body mass index; smoking status; psychiatric or emotional history; seizure frequency and duration; and tumor site, size, and pathology.

Abstract
Brain tumors such as diffuse infiltrating gliomas continue to represent a major clinical challenge. Overall survival for patients diagnosed with glioblastoma, the most common primary brain tumor, remains less than 2 years despite intensive multimodal therapy with surgery, radiation, and chemotherapy. However, advances have been made in standard therapies and novel treatments that are showing great potential. These advances reflect careful study performed in the context of clinical trials. Neurosurgeons have played and will continue to play key parts in these studies. In this manuscript, we review clinical trials in neuro-oncology from a neurosurgical point of view and discuss potential roles for neurosurgeons in advancing glioma therapy in the future.

Abstract
OPINION STATEMENT Central nervous system tumors are a major cause of morbidity and mortality in the United States. Outside of brain metastasis, low- and high-grade gliomas are the most common intrinsic brain tumors. Low-grade gliomas have a 5- and 10-year survival rate of 97 % and 91 %, respectively, when extent of resection is greater than 90 %. High-grade gliomas are extremely aggressive with the vast majority of patients experiencing recurrence and a median survival of 1 to 3 years. Survival of patients with both low- and high-grade gliomas is enhanced with maximal tumor resection. The pursuit of more aggressive extent of resection must be balanced with preservation of functional pathways. Several innovations in neurosurgical oncology have expanded our understanding of individualized patient neuroanatomy, physiology, and function. Emerging imaging technologies as well as intraoperative techniques have expanded our ability to resect maximal amounts of tumor while preserving essential function. Stimulation mapping of language and motor pathways is well-established for the safe resection of intrinsic brain lesions. Additional techniques including neuro-navigation, fluorescence-guided microsurgery using 5-aminolevulinic acid, intraoperative magnetic resonance imaging, and high-frequency ultrasonography can all be used to improve extent of resection in glioma patients.

Abstract
PURPOSE OF REVIEW In recent years, the safety and efficacy of neurosurgical intervention has rapidly improved for brain tumor patients. Technological advances, combined with refined intraoperative techniques, now enable well tolerated surgical access to any region of the human brain. For patients with gliomas, these improvements have redefined the clinical possibilities, and here we review several emerging operative strategies that are essential for next-generation neurosurgical oncologists and major brain tumor centers. RECENT FINDINGS The value of glioma extent of resection remains controversial, but review of the modern literature reveals important opportunities for early neurosurgical intervention. Although microsurgical resection must be balanced by the risk of neurological compromise, improvements in intraoperative stimulation techniques now enable resection of highly eloquent tumors with minimal morbidity. Additionally, the emergence of fluorescence-guided surgery as a new operative paradigm provides a unique opportunity to resect tumors to the margins of microscopic infiltration. SUMMARY Neurosurgical intervention remains the first step in effective glioma management. With intraoperative mapping techniques, aggressive microsurgical resection can be safely pursued even when tumors occupy essential functional pathways. With the development of tumor-specific fluorophores, such as 5-aminolevulinic acid, real-time microscopic visualization of tumor infiltration can be surgically targeted prior to adjuvant therapy.

Abstract
Purpose To analyze initial recurrence patterns in patients with newly diagnosed glioblastoma after radiotherapy plus concurrent and adjuvant temozolomide, and to investigate cumulative recurrence patterns after salvage treatment, including surgery, stereotactic radiotherapy, and chemotherapy. Methods Twenty-one patients with glioblastoma that recurred after concurrent temozolomide and localized radiotherapy were retrospectively analyzed (11 male, 10 female; median age, 57 years; range, 27–74). Disease progression was assessed by new response criteria proposed by the Response Assessment in Neuro-Oncology Working Group of the American Society of Clinical Oncology. The pattern of recurrence was determined by relationships between locations of recurrent tumors and irradiated doses. Central, in-field, marginal, and out-field recurrences were defined relative to the prescribed isodose line. Distant recurrence was operationally defined as subependymal or disseminated disease. Initial and cumulative patterns of recurrence were evaluated in each patient. Results The median follow-up of the recurrent patients was 501 (range, 217–1815) days after initial surgery. Initial recurrences were central in 14 patients (66.7%), in-field in four patients (19.0%), marginal in no patient (0%), out-field in two patients (9.5%), and distant in four patients (19.0%). One patient had both central and in-field recurrences simultaneously, and two had both central and distant recurrences. In the analysis of cumulative recurrence patterns, five patients, who had no scans after initial recurrences, were excluded and the remaining 16 were included. Cumulative recurrences were central in 11 patients (68.8%), in-field in five patients (31.3%), marginal in three patients (18.8%), out-field in five patients (31.3%), and distant in 14 patients (87.5%). Regarding salvage treatments, 11 (52.4%), 11 (52.4%) and 17 (81.0%) patients underwent surgery, stereotactic radiotherapy and chemotherapy, respectively. Eighteen (85.7%) patients had died at the time of analysis, and 16 of them (88.9%) had suffered distant recurrences, which could have been the immediate causes of death. Conclusions Recurrence patterns of glioblastoma after radiotherapy plus concomitant and adjuvant temozolomide were mainly central at first, and distant recurrences were often detected during the clinical course. Much better local control and prevention of distant recurrence, including effective salvage treatment, seem to be important.

Abstract
BACKGROUND High-grade glioma is incurable, with a short survival time and poor prognosis. The increased expression of p75 neurotrophin receptor (NTR) is a characteristic of high-grade glioma, but the potential significance of increased p75NTR in this tumor is not fully understood. Since p75NTR is the receptor for the precursor of brain-derived neurotrophic factor (proBDNF), it is suggested that proBDNF may have an impact on glioma. METHODS In this study we investigated the expression of proBDNF and its receptors p75NTR and sortilin in 52 cases of human glioma and 13 cases of controls by immunochemistry, quantitative real-time PCR, and Western blot methods. Using C6 glioma cells as a model, we investigated the roles of proBDNF on C6 glioma cell differentiation, growth, apoptosis, and migration in vitro. RESULTS We found that the expression levels of proBDNF, p75NTR, and sortilin were significantly increased in high-grade glioma and were positively correlated with the malignancy of the tumor. We also observed that tumors expressed proBDNF, p75NTR, and sortilin in the same cells with different subcellular distributions, suggesting an autocrine or paracrine loop. The ratio of proBDNF to mature BDNF was decreased in high-grade glioma tissues and was negatively correlated with tumor grade. Using C6 glioma cells as a model, we found that proBDNF increased apoptosis and differentiation and decreased cell growth and migration in vitro via p75NTR. CONCLUSIONS Our data indicate that proBDNF and its receptors are upregulated in high-grade glioma and might play an inhibitory effect on glioma.

Abstract
BACKGROUND AND PURPOSE Glioblastoma in the pediatric age group is relatively rare. As a result, it has been difficult to deduce any consistent clinico-radiological and pathological profiles on these patients. Also, the prognostic factors affecting the survival in pediatric glioblastoma are not as well defined as in adults. PATIENTS AND METHODS In this retrospective series, 65 pediatric patients (age ≤ 18 years) from January 1995 to December 2011 with histopathologically proven diagnosis of intracranial glioblastoma were studied. Clinico-radiological, pathological, treatment, and follow-up data were collected. Progression-free and overall survivals were assessed using the Kaplan-Meier method. RESULTS The male-to-female ratio was 2.6:1 with a mean age of 13.29 ± 4.53 years (range 2-18 years). Headache with or without vomiting (n = 51, 78 %), followed by seizures (n = 42, 65 %), and focal deficits (n = 31, 47 %) were the leading symptoms. Forty-nine (75 %) patients had tumors located superficially, whereas there were 16 patients with deeply located glioblastomas (25 %). Gross total tumor excision was achieved in 43 (66 %) patients, while the remaining patients had incomplete excision (n = 22, 34 %). Mean follow-up was 17.7 months (range 1.5-119 months). The median progression-free and overall survivals were 10 and 20 months, respectively. Extent of resection was found to be the independent predictor of survival (p value = 0.002). CONCLUSION Pediatric glioblastomas are associated with longer progression-free as well as overall survivals. Extent of tumor resection is the strongest predictor of survival in pediatric glioblastoma. Hence, an aggressive surgical resection may fetch a better outcome in children with glioblastoma.

Abstract
OBJECTIVE There remains no general consensus in the neurosurgical oncology literature regarding the role of extent of glioma resection in improving patient outcome. Although the value of resection in establishing a diagnosis and alleviating mass effect is clear, there is less certainty in ascertaining the influence of extent of resection (EOR). Here, we review the recent literature to synthesize a comprehensive review of the value of extent of resection for gliomas in the modern neurosurgical era. METHODS We reviewed every major peer-reviewed clinical publication since 1990 on the role of EOR in glioma outcome. RESULTS Thirty-two high-grade glioma articles and 11 low-grade glioma articles were examined in terms of quality of evidence, expected EOR, and survival benefit. CONCLUSION Despite limitations in the quality of data, mounting evidence suggests that more extensive surgical resection is associated with longer life expectancy for both low- and high-grade newly diagnosed gliomas.

Patterns of failure after multimodal treatments for high-grade glioma: effectiveness of MIB-1 labeling index. Radiat Oncol 2012; 7:104. [PMID: 22734595 PMCID: PMC3583446 DOI: 10.1186/1748-717x-7-104] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2011] [Accepted: 06/03/2012] [Indexed: 02/05/2023] Open
Abstract
Background The purpose of the present study was to analyze the recurrence pattern of
high-grade glioma treated with a multimodal treatment approach and to evaluate
whether the MIB-1 labeling index (LI) could be a useful marker for predicting the
pattern of failure in glioblastoma (GB). Methods and materials We evaluated histologically confirmed 131 patients with either anaplastic
astrocytoma (AA) or GB. A median dose was 60 Gy. Concomitant and adjuvant
chemotherapy were administered to 111 patients. MIB-1 LI was assessed by
immunohistochemistry. Recurrence patterns were categorized according to the areas
of recurrence as follows: central failure (recurrence in the 95% of 60 Gy);
in-field (recurrence in the high-dose volume of 50 Gy; marginal (recurrence
outside the high-dose volume) and distant (recurrence outside the RT field). Results The median follow-up durations were 13 months for all patients and
19 months for those remaining alive. Among AA patients, the 2-year
progression-free and overall survival rates were 23.1% and 39.2%, respectively,
while in GB patients, the rates were 13.3% and 27.6%, respectively. The median
survival time was 20 months for AA patients and 15 months for GB
patients. Among AA patients, recurrences were central in 68.7% of patients;
in-field, 18.8%; and distant, 12.5%, while among GB patients, 69.0% of recurrences
were central, 15.5% were in-field, 12.1% were marginal, and 3.4% were distant. The
MIB-1 LI medians were 18.2% in AA and 29.8% in GB. Interestingly, in patients with
GB, the MIB-1 LI had a strong effect on the pattern of failure
(P = 0.014), while the extent of surgical removal
(P = 0.47) and regimens of chemotherapy (P = 0.57) did
not. Conclusions MIB-1 LI predominantly affected the pattern of failure in GB patients treated with
a multimodal approach, and it might be a useful tool for the management of the
disease.

Abstract
Although a primary tenet of neurosurgical oncology is that survival can improve with greater tumor resection, this principle must be tempered by the potential for functional loss following a radical removal. Preoperative planning with functional and physiological imaging paradigms, combined with intraoperative strategies such as cortical and subcortical stimulation mapping, can effectively reduce the risks associated with operating in eloquent territory. In addition to identifying critical motor pathways, these techniques can be adapted to identify language function reliably. The authors review the technical nuances of intraoperative mapping for low- and high-grade gliomas, demonstrating their efficacy in optimizing resection even in patients with negative mapping data. Collectively, these surgical strategies represent the cornerstone for operating on gliomas in and around functional pathways.

Abstract
Refinement of neurosurgical technique has enabled safer operations with more aggressive outcomes. One cornerstone of modern-day practice is the utilization of intraoperative stimulation mapping. In addition to identifying critical motor pathways, this technique can be adapted to reliably identify language pathways. Given the individual variability of cortical language localization, such awake language mapping is essential to minimize language deficits following tumor resection. Our experience suggests that cortical language mapping is a safe and efficient adjunct to optimize tumor resection while preserving essential language sites, even in the setting of negative mapping data. However, the value of maximizing glioma resections remains surprisingly unclear, as there is no general consensus in the literature regarding the efficacy of extent of glioma resection in improving patient outcome. While the importance of resection in obtaining tissue diagnosis and alleviating symptoms is clear, a lack of Class I evidence prevents similar certainty in assessing the influence of extent of resection. Beyond an analysis of modern intraoperative mapping techniques, we examine every major clinical publication since 1990 on the role of extent of resection in glioma outcome. The mounting evidence suggests that, despite persistent limitations in the quality of available studies, a more extensive surgical resection is associated with longer life expectancy for both low-grade and high-grade gliomas.

Abstract
Gliomas are the most common and deadly tumors in the central nervous system (CNS). In the course of studying the role of chemoattractant receptors in tumor growth and metastasis, we discovered that highly malignant human glioblastoma and anaplastic astrocytoma specimens were stained positively for the formylpeptide receptor (FPR), which is normally expressed in myeloid cells and accounts for their chemotaxis and activation induced by bacterial peptides. Screening of human glioma cell lines revealed that FPR was expressed selectively in glioma cell lines with a more highly malignant phenotype. FPR expressed in glioblastoma cell lines mediates cell chemotaxis, proliferation and production of an angiogenic factor, vascular endothelial growth factor (VEGF), in response to agonists released by necrotic tumor cells. Furthermore, FPR in glioblastoma cells activates the receptor for epidermal growth factor (EGFR) by increasing the phosphorylation of a selected tyrosine residue in the intracellular tail of EGFR. Thus, FPR hijacked by human glioblastoma cells exploits the function of EGFR to promote rapid tumor progression.

Abstract
PURPOSE We investigated the effects of fractionated radiation treatments on the life spans of athymic rats bearing intracerebral brain tumors. METHODS AND MATERIALS U-251 MG or U-87 MG human glioblastoma cells were implanted into the brains of athymic rats, and the resulting tumors were irradiated once daily with various doses of ionizing radiation for 5 consecutive days or for 10 days with a 2-day break after Day 5. RESULTS Five daily doses of 1 and 1.5 Gy, and 10 doses of 0.75 and 1 Gy, cured some U-251 MG tumors. However, five daily doses of 0.5 Gy increased the survival time of animals bearing U-251 MG tumors 5 days without curing any animals of their tumors. Ten doses of 0.3 Gy given over 2 weeks extended the lifespan of the host animals 9 days without curing any animals. For U-87 MG tumors, 5 daily doses of 3 Gy produced an increased lifespan of 8 days without curing any animals, and 10 doses of 1 Gy prolonged lifespan 5.5 days without curing any animals. The differences in extension of life span between the 5- and 10-fraction protocols were minor for either tumor type. CONCLUSION The finding that the U-251 MG tumors are more sensitive than U-87 MG tumors, despite the fact that U-251 MG tumors contain many more hypoxic cells than U-87 MG tumors, suggests the intrinsic cellular radiosensitivities of these cell lines are more important than hypoxia in determining their in vivo radiosensitivities.

Abstract
Object
To investigate the prognostic significance of the volumetrically assessed extent of resection on time to tumor progression (TTP), overall survival (OS), and tumor recurrence patterns, the authors retrospectively analyzed preoperative and postoperative tumor volumes in 102 adult patients from the time of the initial resection of a hemispheric anaplastic astrocytoma (AA).
Methods
The quantification of tumor volumes was based on a previously described method involving computerized analysis of magnetic resonance (MR) images. Analysis of contrast-enhancing tumor volumes on T1-weighted MR images was conducted for 67 patients who had contrast-enhancing tumors. Measurements of T2 hyperintensity were obtained for all 102 patients in the study.
The presence or absence of preresection enhancement, actual volume of this enhancement, and the percentage of preoperative enhancement as it relates to the total T2 tumor volume did not have a statistically significant relationship to TTP or OS. In addition to age, the volume of residual disease measured on T2-weighted MR images was the most significant predictor of TTP (p < 0.001), and residual contrast-enhancing tumor volume was the most significant predictor of OS (p = 0.003) on multivariate analysis. In contrast to low-grade gliomas, there was no statistically significant relationship between the extent of resection and histological characteristics at the time of recurrence, that is, tumor Grade III compared with Grade IV.
Conclusions
Data from this retrospective analysis of a histologically uniform group of hemispheric AAs treated in the MR imaging era suggest that residual tumor volumes, as documented on postoperative imaging studies, may be a prognostic factor for TTP and OS for this patient population.

Abstract
Telomerase is a ribonucleoprotein complex that elongates telomeric DNA and appears to play an important role in cellular immortalization of cancers. Because telomerase is expressed in the vast majority of malignant gliomas but not in normal brain tissues, it is a logical target for gliomaspecific therapy. The telomerase inhibitor GRN163, a 13-mer oligonucleotide N3'-->P5' thio-phosphoramidate (Geron Corporation, Menlo Park, Calif.), is complementary to the template region of the human telomerase RNA subunit hTR. When athymic mice bearing U-251 MG human brain tumor xenografts in their flanks were treated intratumorally with GRN163, a significant growth delay in tumor size was observed (P < 0.01 in all groups) as compared to the tumor size in mice receiving a mismatched oligonucleotide or the carrier alone. We also investigated biodistribution of the drug in vivo in an intracerebral rat brain-tumor model. Fluorescein-labeled GRN163 was loaded into an osmotic minipump and infused directly into U-251 MG brain tumors over 7 days. Examination of the brains revealed that GRN163 was present in tumor cells at all time points studied. When GRN163 was infused into intracerebral U-251 MG tumors shortly after their implantation, it prevented their establishment and growth. Lastly, when rats with larger intracerebral tumors were treated with the inhibitor, GRN163 increased animal survival times. Our results demonstrate that the antitelomerase agent GRN163 inhibits growth of glioblastoma in vivo, exhibits favorable intracerebral tumor uptake properties, and prevents the growth of intracerebral tumors. These findings support further development of this compound as a potential anticancer agent.

Abstract
OBJECT Glioblastoma multiforme (GBM) remains incurable by conventional treatments, although some patients experience long-term survival. A younger age, a higher Karnofsky Performance Scale (KPS) score, more aggressive treatment, and long progression-free intervals have been reported to be positively associated with long-term postoperative patient survival. The aim of this retrospective study was the identification of additional favorable prognostic factors affecting long-term survival in surgically treated adult patients with supratentorial GBM. METHODS Of 113 adult patients newly diagnosed with histologically verified supratentorial GBM who were enrolled in Phase III trials during the period between 1987 and 1998, six (5.3%) who survived for longer than 5 years were defined as long-term survivors, whereas the remaining 107 patients served as controls. All six were women and were compared with the controls; they were younger (mean age 44.2 years, range 31-60 years), and their preoperative KPS scores were higher (mean 85, range 60-100). Four of the six patients underwent gross-total resection. In five patients (83.3%) the progression-free interval was longer than 5 years and in three a histopathological diagnosis of giant cell GBM was made. This diagnosis was not made in the other 107 patients. CONCLUSIONS Among adult patients with supratentorial GBM, female sex and histopathological characteristics consistent with giant cell GBM may be predictive of a better survival rate, as may traditional factors (that is, younger age, good KPS score, more aggressive resection, and a long progression-free interval).

Abstract
The impact of various clinical pretreatment prognostic factors in patients with malignant glioma treated with a combined modality approach was investigated in 229 patients treated on four consecutive prospective phase II studies. The median survival time for all 229 patients is 14 months, and 2- and 5-year survival rates are 34%, and 9%, respectively. The median time to tumor progression is 14 months, and 2- and 5-year progression-free survival rates are 32%, and 9%, respectively. Females did better than males, while patients 55 years or less did better than those more than 55 years. Patients with Karnofsky performance status (KPS) 80 to 100 did better than those with KPS 50 to 70 as well as did patients having preoperative tumor sizes 4 cm or less when compared to those with larger tumors. Frontal tumor location as well as more extensive surgery favorably influenced survival. Patients harboring anaplastic astrocytoma fared significantly better than those with glioblastoma multiforme. Both univariate and multivariate Cox analyses confirmed independent influence of these prognosticators. When progression-free survival was used as an endpoint, all seven variables remained independent prognosticators. This study showed that sex, age, KPS, tumor size, tumor location, histology, and extent of surgery are independent prognosticators in patients with malignant glioma treated with combined modality approach.

Abstract
Although different prognostic indices for malignant gliomas have been developed, their validity outside of clinical trials has not been widely tested. The aim of this study was to determine whether the Medical Research Council (MRC) brain tumour prognostic index was able to stratify patients for survival managed in routine practice, and secondly to compare the results with our newly developed prognostic score which included tumour grade and only 3 prognostic groups. The MRC and the new prognostic index were calculated for a group of 119 adult patients with malignant glioma managed by surgical resection/biopsy and post-operative radiotherapy. For the MRC and new score, 6 and 3 prognostic groups were defined, respectively. For all patients median survival was 11 (2-66) months. The overall survival rate at 12 and 24 months were 43% and 18%, respectively. The MRC median and two-year survival rates were 14 months and 26% for a score of 1-10, 14 months and 27% for a score of 11-15, 13 months and 22% for a score of 16-20, 8 months and 10% for a score of 21-25, 8 months and 0% for those scoring 26-33. There was only one patient in the 34-38 group. For the new prognostic index, median and two-year survival rates were respectively 16 and 26%; 12 and 23%; 8 and 7% for the good, intermediate and poor prognostic groups. Both indices were significant factors for survival in univariate analysis (MRC index, p = 0.0089, new index p = 0.0002), but not in multivariate analysis. Both the MRC and our newly devised prognostic score were able to separate patients into good and poor prognostic groups, which may aid in treatment decisions, although there was less differentiation between the MRC groups especially over the first year. Both scores use routinely available factors. However, inclusion of tumour grade in the new score may be an advantage over the MRC index.

Abstract
Low-grade gliomas are a diverse group of neoplasms which, as the name implies, are thought to arise from glial cells. Common among this group are astrocytomas (low-grade astrocytoma; LGA), oligodendrogliomas and mixed gliomas. Among these, LGA is the commonest low-grade glioma and, occasionally, although incorrectly, the terms are used interchangeably. Advances in imaging technology have improved the accuracy of preoperative diagnosis. The management of low-grade gliomas is controversial. Recent evidence suggests that previously considered standard therapy (i.e. surgery plus radiotherapy) may not be in the patient's best interests. A review of the available published research concerning low-grade gliomas is therefore timely.

Abstract
BACKGROUND The incidence of brain tumors is increasing rapidly, particularly in the older population. Advances in molecular biology help to explain differences in biologic behavior and response to therapy of brain tumors in the elderly compared with younger patients. The number of elderly patients who desire and receive therapy for brain tumors and are included in clinical trials is increasing. METHODS This article reviews the literature on the epidemiology, clinical aspects, and therapy of brain tumors, with emphasis on the older patient population. RESULTS The increased incidence of brain tumors in the elderly is principally due to the increasing number of people who comprise the older population. Age and performance status are important independent prognostic indicators, together with tumor histology. Surgery, radiation therapy, and chemotherapy can benefit elderly patients with brain tumors with favorable histologies, tumor location, and good performance status. The response rates to available therapies are less favorable than in younger patients, and only a small number of elderly patients are enrolled in clinical studies addressing new treatment modalities. CONCLUSIONS Brain tumors in the elderly have specific characteristics that determine their biologic behavior and response to therapy. There is a need for clinical studies designed for treatment of brain tumors in older patients, and requirements for rehabilitation and support systems for the elderly need to be addressed.

Abstract
Low grade astrocytomas are common brain neoplasms that primarily affect young adults. Although these patients often have a reasonably long survival, most will ultimately succumb to their tumours. Often the tumours progress to higher grade astrocytomas. The optimal management plan for these tumours is controversial and ranges from observation to macroscopic excision, radiotherapy and chemotherapy. The evidence for each of these approaches is presented in this review and a management algorithm is presented.

Abstract
The impact on survival of postradiation nitrosourea-containing chemotherapy (CHT) in patients with glioblastoma multiforme (GM) was analyzed retrospectively in 133 patients who completed the planned radiotherapy out of 173 observed cases. Thirty-five patients were < 50 years old, 89 were males, 20 had performance status (PS) < 70 and 72 > or = 70. Surgery was followed by radiotherapy in all cases (50-60 Gy in 95 patients, 61-70 Gy in 38 patients). At the end of radiotherapy, 43 patients received CHT, whereas 90 patients did not receive further therapy. At univariate analysis, age < 50 years, feminine gender, subtotal or total resection, radiotherapy doses > 60 Gy, and CHT had an independent prognostic value. Our results suggest that chemotherapy improves 2-year survival rates from 12% to 28% in GM. The sequence of treatment, new drugs, and combinations should be further explored.

Abstract
Between April, 1992 and December, 1995, forty consecutive patients with a cerebral malignant glioma (WHO Grade III and IV) were enrolled in a trial consisting in surgery and post-operative administration of radiotherapy (4500-6000 cGy), carboplatin (CBDCA; dose of 450-600 mg/m2), and oral tamoxifen (TAM; at doses of 40, 80 or 120 mg/day). Two patients of the TAM group died in the postoperative period from a pulmonary embolism and myocardial infarction, respectively. The patients (all dosages combined) had a median survival time of 13 months from the time of diagnosis. The 12-month and 24-month survival rates were 52% and 32%, respectively. The median relapse-free survival time was 7 months. Patients treated with higher doses of TAM (80-120 mg/day) demonstrated a longer median survival rate (13 months both) and a longer 12-month survival result (58% and 76%, respectively). Patients who assumed TAM for a period longer than 3 months (group +3) have a higher median survival rate (16 months) and better 12-month and 24-month results (62% and 40%, respectively). Moreover, the median relapse-free survival time was 10 months (versus 6 months in group -3; p = 0.0038). However, it is not possible to exclude that patients of group +3 had a slower growing or a stable tumor and were well enough to assume TAM for a longer period. The results observed in the TAM-group have been compared with those of 40 matched controls treated with surgery, radiotherapy and CBDCA. These patients had a median survival time of 9 months (p = 0.04) and the 12-month and 24-month survival rates were 30% and 0%, respectively. The median relapse-free survival time was 4 months (p = 0.0014). These data suggest a potential role for combinational TAM-CBDCA therapy in the post-operative treatment of cerebral malignant gliomas; further clinical phase III trials, especially those with higher dosages of TAM are warranted.

Abstract
Results of altered therapy schedules obtained in postoperative treatment of 294 patients with malignant gliomas over last 20 years are presented. During this period 135 patients received Conventional Irradiation and Chemotherapy (CICH), 61 patients received Conventional Irradiation (CI), 59 patients received Split Course High Fractional Dose Irradiation (SCHFDI), and 39 patients received Twice a Day Accelerated Irradiation (TDAI). Actuarial survival rates at 2, 3 and 5 years were 19%, 7%, 0% respectively for patients treated with CICH, and they were 21%, 10%, 0% for CI group, 24%, 12%, 0% for SCHFDI option and 15%, 8%, 0% for TDAI schedule. According to the Cox proportional hazard model, only age was significant factor in prognosis.

Abstract
PURPOSE A new radiotherapy schedule to treat glioblastoma multiforme after surgery, combining nicotinamide and carbogen. METHODS AND MATERIALS We analyzed 36 patients with glioblastoma multiforme treated after surgery with radiotherapy, Nicotinamide and Carbogen as follows: 7 patients were treated with accelerated fractionation: two fractions/day, 1.5 cGy/fraction, 6 h interval, 5 days/week, total dose 60 Gy in 4 weeks; 8 patients were treated with the same irradiation scheduling plus Nicotinamide at the dose of 4 g and 2 g in capsules, respectively, 1 h before the first and the second irradiation fraction; 21 patients were treated with accelerated radiotherapy, Nicotinamide, and Carbogen (inhaled 10 min before radiotherapy and during the whole course of irradiation). On the basis of surgical removal our patients were subdivided in three groups: totally resected, with residual tumor <50%, or >50%. Radiotherapy with accelerated fractionation was completed in the scheduled time without side effects on the whole group of patients and Carbogen inhalation did not cause significant change of cardiopulmonar parameters. The toxicity observed was predominant in the gastrointestinal tract and was related to Nicotinamide. RESULTS The median survival time (M.S.T.) was 10 months, as reported by others authors with conventional treatment, but in patients without surgical residual tumor and submitted to the complete treatment schedule, the survival at 35 months was around 25%. CONCLUSIONS We conclude that this method is feasible with acceptable toxicity; analyzing the survival curves appears to be a trend towards an improvement in survival in the subgroup of patients with gross total removal treated with the combination of Carbogen, Nicotinamide, and accelerated fractionation.

Abstract
From February 1989 to December 1992, 31 patients who presented with an initial pathological diagnosis of glioblastoma multiforme underwent tumor debulking or biopsy, stereotactic radiosurgery, and standard radiation therapy as part of their primary treatment. Presenting characteristics in the 22 men and nine women included a median age of 57 years, Karnofsky Performance Scale score median of 80, and median tumor volume of 16.4 cm3. Stereotactic radiosurgery delivered a central dose of 15 to 35 Gy with the isocenter location, collimator size, and beam paths individualized by means of three-dimensional software developed at the University of Wisconsin. The peripheral isodose line varied from 40% to 90% with a median of 72.5% and a mode of 80%. The mean follow-up period was 12.84 months with a median of 9.5 months. Statistical analysis was performed using Kaplan-Meier analysis and log-rank comparison of risk factor groups. The parameters of age, initial Karnofsky Performance Scale score, and biopsy were significantly different in patient survival from debulking; but no difference was noted between single and multiple isocenters and patterns of steroid requirement. Radiographic recurrences were divided by location into the following categories: central (within central stereotactic radiosurgery dose), 0; peripheral (within 2 cm of central dose), 19; and distant (> 2 cm), 4. There is no evidence of recurrence in five surviving patients. Actuarial 12-month survival was 37%, with a median survival of 9.5 months. These values are similar to previous results for surgery and standard radiotherapy alone. The results suggest that the curative value of radiosurgery is significantly limited by peripheral recurrences.

Abstract
BACKGROUND In supratentorial low-grade astrocytoma, radiation therapy effects and prognostic factors, especially with respect to computed tomography (CT) findings, are not yet well established. A retrospective analysis of 119 patients with this disease (histologically confirmed ordinary astrocytoma) therefore was conducted. METHODS Between 1965 and 1989, 101 patients received postoperative radiation therapy, whereas 18 patients received surgery alone. Radiation was directed to the tumor plus a 1- to 3-cm margin in almost all cases; the dose range was 41 to 66 Gy (mean, 57 Gy). CT scan was performed before treatment on 74 patients. Postoperative survival rates were compared by both univariate and multivariate analyses. RESULTS The 5- and 10-year survival rates for the irradiated group were 60% and 41%, respectively, which were significantly better than those for the surgery-alone group (37% and 11%, P = 0.048). Among various potential prognostic factors for the irradiated patients, only a lower age was associated with a better prognosis. Sex, tumor site (deep-seated or not), extent of surgery, radiation dose and field, and adjuvant chemotherapy did not influence the prognosis significantly. Among various CT findings, a clear tumor margin, a maximum tumor area less than 25 cm2, presence of a cyst, and lack of mass effect were associated with a better prognosis on univariate analysis (P = 0.02-0.12), but contrast enhancement was not related to prognosis. On multivariate analysis, however, mass effect was the only significant factor. CONCLUSIONS Radiation therapy appears definitely to be effective in improving the prognosis for low-grade astrocytoma. Younger age, and the absence of mass effect determined by CT, were associated significantly with a better prognosis.

Abstract
A prospective randomized study of 108 patients with cerebral malignant gliomas was carried out at the Department of Radiation Oncology of Maria Sklodowska-Curie Memorial Center in Kraków. 44 patients with histologically proven glioblastoma multiforme and 64 patients with anaplastic astrocytoma received postoperative radiotherapy. Patients were randomized to two treatment arms: Conventionally Fractionated Radiotherapy (CFR) and Hypofractionated Radiotherapy (HF). In the CFR group, the whole brain was irradiated to the total dose of 50 Gy in 25 fractions over 5 weeks, then a 10 Gy 'boost' in 5 fractions in 5 days was delivered to the site of the primary lesion. In the HF group, there were 3 courses of irradiation separated by a one month interval. In each of the two first series the patients received 20 Gy in 5 fractions in 5 days to the whole brain, and in the third course, 10 Gy 'boost' in 5 days was delivered as in the CFR regimen. The tolerance to treatment has been found to be good in both groups. The 2-year actuarial survival rate for patients with anaplastic astrocytoma was 22% for CFR and 18% for HF. Patients with glioblastoma multiforme treated with HF had a better prognosis in comparison to the CFR group with the two-year actuarial survival rates being 23% and 10%, respectively. This difference is statistically significant at the 0.05 level.

Abstract
This review discusses some of the recent advances in glioma research and treatment. Our understanding of the characteristics of these tumors has been strengthened by the application of molecular biologic and genetic techniques to pathologic grading and therapy outcome. Newer attempts to correlate imaging modalities to pathologic grading are also discussed. It is anticipated that these developments will strengthen our ability to design improved treatment strategies, an essential goal inasmuch as current treatment schemes have limited benefit. More work needs to be done to understand the biology of these tumors especially the complex interactions of their cytokine expression, multiplicity of genetic abnormalities, and their local environment. Only then will be able to develop improved therapeutic interventions.

Abstract
103 patients with the diagnosis of AAF were identified from the RT/BCNU arms of 3 RTOG malignant glioma trials. Pre-treatment tumor size was less than 5 cm for 48% and greater than or equal to 5 cm for 52%, and tumor sites were frontal lobe in 55%, temporal in 25%, and parietal in 16%. Surgery consisted of biopsy for 30%, partial resection for 56%, and total resection for 14%. Extent of surgery correlated with age, with 81% of patients less than 40 undergoing partial/total resection vs. 60% of those over 40 (P = 0.019). The median survival time (MST) of patients undergoing partial/total resection was 49 mo., vs. 18 mo. for those biopsied only (P = 0.002). Patients with frontal location had longer MST than those with non-frontal lesions (MST: 49 vs. 25 mo., P = 0.047), while no survival difference was apparent by univariate analysis of tumor size. Multivariate analysis demonstrated that only younger age, frontal location, and smaller tumor size correlated significantly with extended survival. Extent of surgery was not predictive. The close correlation between young age and extensive surgery obscures the survival advantage for greater surgery seen with univariate analysis. Smaller tumor size and frontal location favorably influence outcome even when adjusted by age.
