[PMID: 37972737 DOI: 10.1016/j.radonc.2023.110012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2023] [Revised: 10/30/2023] [Accepted: 11/01/2023] [Indexed: 11/19/2023]
Abstract
PURPOSE To evaluate the clinical efficacy and toxicity of brachytherapy as a salvage therapy for patients with recurrent glioblastoma (rGBM). METHODS AND MATERIALS We searched the PubMed, Embase, and Cochrane libraries from its inception to June 2023, for eligible studies in which patients underwent brachytherapy for rGBM. Outcomes of interest were mOS, mPFS, OS, PFS, and adverse events (AEs). For individual clinical survival outcomes and common AEs, weighted-mean descriptive statistics were calculated as a summary measure using study sample size as the weight. The calculation formula is as follows: weighted-mean = Σwx/Σw (w is the sample size and x is the outcome). RESULTS This review included 29 studies with a total of 1202 rGBM patients, including 22 retrospective and 7 prospective studies. The results showed that from the time of brachytherapy, the mOS and mPFS were 6.8 to 24.4 months and 3.7 to 11.7 months. The OS of 6 months, 1 year, 18 months, 2 years, and 3 years after brachytherapy were 58.3 % to 85.2 % (weighted-mean 76.2 %), 26 % to 66 % (weighted-mean 41.9 %), 20 % to 37 % (weighted-mean 27.6 %), 11 % to 23 % (weighted-mean 14.8 %), and 8 % to 15 % (weighted-mean 12.1 %), respectively. The PFS of 6 months and 1 year after brachytherapy were 26.7 % to 86 % (weighted-mean 53.4 %) and 14 % to 81 % (weighted-mean 24.1 %). Most patients with rGBM will experience treatment failure again during the follow-up period, mainly local (10.7 % to 79.4 %) or marginal(3.6 % to 22.2 %) recurrence, followed by distant failure (6.7 % to 57.7 %). Although therapeutic AEs had not been uniformly reported, the overall toxicity rate was considered to be low. The common AEs reported included progressive neurologic deterioration, seizures, CSF leak, brain necrosis, hemorrhage, and infection/meningitis, with a weighted-mean incidence of 1.9 %, 2.4 %, 4.1 %, 5.4 %, 2.1 %, and 3.8 %, respectively. CONCLUSIONS The evidence summarized above, albeit mostly level III, suggests that brachytherapy has acceptable safety and good post-treatment clinical efficacy for selected patients with rGBM. Well-designed, high-quality, large-sample randomized controlled and prospective studies are needed to further validate these findings.

Abstract
AbstractObjective. –We studied the relationship between depressive symptoms and quality of life (QOL) as well as functional status in primary brain tumor patients at recurrent measurements. Differences in QOL between depressive and non-depressive samples by gender were controlled for tumor characteristics and patients' psychosocial factors.Materials and methods. –The data consisted of 77 patients with a primary brain tumor, 30 males and 47 females. Depression of the patients was assessed by Beck Depression Inventory (BDI) and Crown-Crisp Experiential Index (CCEI), functional status by Karnofsky Performance scale (KPS) and QOL by Sintonen's 15D before tumor operation as well as at 3 months and at 1 year from surgical operation of the tumor.Results.The level of QOL in females was lower compared to that of males. Depression was the main predictor for worse QOL in the patients at all measurements. Depressive patients with a benign brain tumor had significantly worse QOL versus non-depressive ones.Discussion and conclusion. –Decreased QOL was strongly related to depression, especially among patients with a benign brain tumor. Further studies are needed to find whether sufficient depression therapy improves the QOL of patients.

Abstract
PURPOSE To determine the efficacy and toxicity of re-irradiation for patients with recurrent GBM. MATERIALS AND METHODS We searched various biomedical databases from 1998 to 2018, for eligible studies where patients were treated with re-irradiation for recurrent GBM. Outcomes of interest were 6 and 12-month overall survival (OS-6, OS-12), 6 and 12-month progression free survival (PFS-6, PFS-12) and serious (Grade 3 +) adverse events (AE). We used the random effects model to pool outcomes across studies and compared pre-defined subgroups using interaction test. Methodological quality of each study was assessed using the Newcastle-Ottawa scoring system. RESULTS We found 50 eligible non-comparative studies including 2095 patients. Of these, 42% were of good or fair quality. The pooled results were as follows: OS-6 rate 73% (95% confidence interval (CI) 69-77%), OS-12 rate 36% (95% CI 32-40%), PFS-6 rate 43% (95% CI 35-50%), PFS-12 rate 17% (95% CI 13-20%), and Grade 3 + AE rate 7% (95% CI 4-10%). Subgroup analysis showed that prospective studies reported higher toxicity rates, and studies which utilized brachytherapy to have a longer OS-12. Within the external beam radiotherapy group, there was no dose-response [above or below 36 Gy in 2 Gy equivalent doses (EQD2)]. However, a short fractionation regimen (≤ 5 fractions) seemed to provide superior PFS-6. CONCLUSION The available evidence, albeit mostly level III, suggests that re-irradiation provides encouraging disease control and survival rates. Toxicity was not uniformly reported, but seemed to be low from the included studies. Randomized controlled trials (RCT) are needed to establish the optimal management strategy for recurrent GBM.

Abstract
Aims and background The present study evaluated toxicity, local control, and survival in patients with relapsed high-grade glioma after surgery and external beam radiation therapy and treated with re-operation and GliaSite brachytherapy. Methods Between 2006 and 2008, 15 patients with recurrent high-grade glioma underwent re-operation and GliaSite brachytherapy. Ten patients were males and 5 females. Median age was 40 years (range, 20–71). Karnofsky performance status was ≥70. All patients but one received GliaSite irradiation of the surgical cavity wall at the dose of 4500 cGy at a depth of 1 cm. Results No severe acute side effects were observed during GliaSite brachytherapy. Pathologically documented, symptomatic late radiation necrosis was observed in 3 patients (20%); 2 subsequently died of further complications. Two patients were alive at a median follow-up 13 months (range, 1–30). Median overall survival after GliaSite brachytherapy was 13 months. Conclusions Patients with recurrent high-grade glioma can be treated with additional surgery and GliaSite brachytherapy, delivering 4500 cGy at 1 cm depth without significant acute side effects but with a significant rate (20%) of late radiation necrosis, resulting in 13% of treatment-related deaths. Compared with the literature, survival results in our study appear to be satisfactory, but they may be related to patient selection criteria. Re-intervention followed by GliaSite brachytherapy should not be offered as a standard treatment for recurrent high-grade glioma, because of the high rate of late complications, treatment-related deaths, and high treatment costs.

Abstract
Neovascularization is a common phenomenon in gliomas. MR imaging cerebral blood volume (CBV) mapping utilizes ultrafast echo-planar imaging and simultaneous use of gadolinium-based contrast material. To determine the utility of MR CBV mapping in the clinical evaluation of gliomas, we followed 15 patients with serial studies. This technique provided functional information that was not evident with conventional CT or MR imaging. Low-grade tumors demonstrated homogeneously low CBV, while high-grade tumors often showed areas of both high and low CBV The maximum tumor CBV/white matter ratio was compared between low- (n = 3) and high-grade gliomas (n=5) in patients without previous treatment and with histologic verification (n=8) and was significantly higher in high-grade gliomas (p<0.01). High CBV foci in nonenhancing tumor areas were present in 2 cases. The distinction between radiation necrosis and active tumor could be made correctly in 3 of 4 cases. The information provided by MR CBV mapping has the potential to be an adjunct in the clinical care of glioma patients.

Abstract
The current study analyzed the outcome after stereotactic brachytherapy (SBT) using iodine-125 seeds in anaplastic astrocytoma, oligoastrocytoma or oligodendroglioma not suitable for resection. Out of 223 patients harbouring a malignant glioma treated according to a prospective protocol, 172 patients were selected who received SBT to treat a WHO grade III de-novo/residual tumor (n = 99) or a tumor recurrence after multimodal treatment (n = 73). We assessed progression free survival (PFS), overall survival (OS), radiological and clinical outcome and determined prognostic factors using univariate and multivariate regression analyses. The median follow-up time was 38 months. Median OS and median PFS was 28.9 and 21.4 months in the de-novo group vs. 49.4 and 32.6 months in the recurrence group. Recurrent tumors had more frequently (p = 0.01) an oligodendroglial-component compared to de novo tumors. According to cohort-specific univariate analyses KPS at SBT had a significant (p = 0.008) impact on OS in the de-novo group. In the recurrence group, (Cox regression analysis) OS was significantly associated with histology subtype (oligoastro-/oligodendroglioma vs. astrocytoma, p = 0.043). Transient and permanent morbidity (~1 %) was low. For patients unable to undergo surgery due to eloquent tumour location or reduced general condition SBT is an effective treatment option, which does not foreclose additional therapeutic interventions.

Abstract
Background:We compared the functional status and survival time of patients with malignant gliomas.Methods:This retrospective review included 143 patients diagnosed with malignant gliomas. Patients were grouped according to histopathological diagnosis. To measure functional status, patients were assigned a Karnofksy performance status (KPS) score at the time of presentation and at one, three, six, nine, 12 months and yearly intervals thereafter. Data were analyzed using descriptive methods as well as Kruskal-Wallis tests, Chi-square tests, Log-Rank tests and Cox’s proportional hazards modeling.Results:Eighty-four patients were male. The median age of patients was 63 years. One hundred and seven patients had a histopathological diagnosis of glioblastoma multiforme, 23 of anaplastic astrocytoma and 13 of anaplastic oligodendroglioma. Twenty-nine patients received aggressive multimodal treatment, 83 received intermediate treatment and the remaining 31 patients received conservative therapy. Significant treatment complications occurred in 33% of patients including four post-operative deaths. The anaplastic oligodendroglioma group had lower mortality and maintained better KPS scores over time, as did patients receiving full treatment. The most significant prognostic factors for functional status included age, pretreatment KPS, and type of treatment received. The most significant factors associated with time until death included age, severity of comorbidities, pretreatment KPS, presence of confusion, histopathological diagnosis and type of treatment received.Conclusion:In patients with malignant gliomas, younger age, better functional status at presentation and aggressive multimodal treatment were associated with improved longer-term functional status and survival. Confirmation of the effect of multimodal treatment on patient functional status would require a randomised controlled clinical trial.

Abstract
Background:Very long term survival after diagnosis of malignant glioma has been described in individual case reports. Survival of more than 10 years is extremely rare, especially when identified in 3 out of 71 patients assigned to one arm of a randomized controlled trial.Patients:Three patients survived 11, 16, and 18 years following the diagnosis of glioblastoma and treatment with surgery, conventional fractionated radiation, and high-activity iodine-125 boost brachytherapy as part of a randomized controlled trial.Conclusion:Despite this apparent cause and effect relationship, statistical analysis shows no relationship between these cures and treatment with brachytherapy. Cure of glioblastoma remains rare.

Abstract
To determine whether immediate post-operative brachytherapy can be safely applied to newly diagnosed glioblastomas to retard tumor progression prior to initiation of external beam radiation therapy (EBRT) and temozolomide. Between 1996 and 2011, eleven patients underwent implantation of GliaSite (n = 9) or MammoSite (n = 2) at the time of surgical resection. Brachytherapy was carried out on post-operative day 2-3, with 45-60 Gy delivered to a 1 cm margin. All patients underwent subsequent standard radiation/temozolomide treatment 4-5 weeks post-irradiation. There were no wound related complications. Toxicity was observed in two patients (2/11 or 18 %), including one post-operative seizure and one case of cerebral edema that resolved after a course of steroid treatment. Immediate post-operative and pre-irradiation/temozolomide magnetic resonance imaging assessment was available for 9 of the 11 patients. Two of these nine patients (22 %) developed new regions of contrast enhancement prior to irradiation/temozolomide. This compares favorably to historical data where 53 % of patient suffer such tumor progression. While there was a trend toward improved 6 month progression free survival in the brachytherapy/temozolomide/radiation treated patients, the overall survival of these patients were comparable to historical controls. This case series demonstrates the safety of immediate post-operative brachytherapy when applied prior to EBRT and temozolomide in the treatment of newly diagnosed glioblastomas.

Abstract
Over the last quarter century there has been significant progress toward identifying certain characteristics and patterns in GBM patients to predict survival times and outcomes. We sought to identify clinical predictors of survival in GBM patients from the past 24 years. We examined patient survival related to tumor locations, surgical treatment, postoperative course, radiotherapy, chemotherapy, patient age, GBM recurrence, imaging characteristics, serum, and molecular markers. We present predictors that may increase, decrease, or play no significant role in determining a GBM patient's long-term survival or affect the quality of life.

Abstract
OBJECTIVES Tumour recurrence of glioblastoma multiforme (GBM) after initial treatment with surgical resection, radiotherapy and chemotherapy is an inevitable phenomenon. This retrospective cohort study compared the efficacy of interstitial high dose rate brachytherapy (HDR-BRT), re-resection and sole dose dense temozolomide chemotherapy (ddTMZ) in the treatment of recurrent glioblastoma after initial surgery and radiochemotherapy. DESIGN Retropective cohort study. SETTING Primary level of care with two participating centres. The geographical location was central Germany. PARTICIPANTS From January 2005 to December 2010, a total of 111 patients developed recurrent GBM after initial surgery and radiotherapy with concomitant temozolomide. The inclusion criteria were as follows: (1) histology-proven diagnosis of primary GBM (WHO grade 4), (2) primary treatment with resection and radiochemotherapy, and (3) tumour recurrence/progression. INTERVENTIONS This study compared retrospectively the efficacy of interstitial HDR-BRT, re-resection and ddTMZ alone in the treatment of recurrent glioblastoma. PRIMARY AND SECONDARY OUTCOME MEASURES Median survival, progression free survival and complication rate. RESULTS Median survival after salvage therapy of the recurrence was 37, 30 and 26 weeks, respectively. The HDR-BRT group did significantly better than both the reoperation (p<0.05) and the ddTMZ groups (p<0.05). Moderate to severe complications in the HDR-BRT, reoperation and sole chemotherapy groups occurred in 5/50 (10%), 4/36 (11%) and 9/25 (36%) cases, respectively. CONCLUSIONS CT-guided interstitial HDR-BRT attained higher survival benefits in the management of recurrent glioblastoma after initial surgery and radiotherapy with concurrent temozolomide in comparison with the other treatment modalities. The low risk of complications of the HDR-BRT and the fact that it can be delivered percutaneously in local anaesthesia render it a promissing treatment option for selected patients which should be further evaluated.

Abstract
Radiation therapy forms one of the building blocks of the multi-disciplinary management of patients with brain tumors. Improved survival following radiation therapy may come with a cost, including the potential complication of radiation necrosis. Radiation necrosis impacts the quality of life in cancer survivors, and it is essential to detect and effectively treat this entity as early as possible. Significant progress in neuro-radiology and molecular pathology facilitate more straightforward diagnosis and characterization of cerebral radiation necrosis. Several therapeutic interventions, both medical and surgical, may halt the progression of radiation necrosis and diminish or abrogate its clinical manifestations, but there are still no definitive guidelines to follow explicitly that guide treatment of radiation necrosis. We discuss the pathobiology, clinical features, diagnosis, available treatment modalities, and outcomes in the management of patients with intracranial radiation necrosis that follows radiation used to treat brain tumors.

Abstract
Radiotherapy still remains the most effective adjunctive therapy for malignant gliomas following surgery and provides useful local control for some benign tumors. Research efforts have been directed towards several aspects of the radiation therapy of tumors. The results of clinical trials undertaken in the last decade offer some basis for optimism in the management of patients with malignant brain tumors, although cure is still not a realistic objective. This review focuses on the rationale and radiobiological basis for recent developments in the radiotherapy of adult brain tumors. The salient issues are discussed from a neurosurgeon's perspective.

Abstract
Iodine-125 brachytherapy has been applied to brain tumours since 1979. Even though the physical and biological characteristics make these implants particularly attractive for minimal invasive treatment, the place for stereotactic brachytherapy is still poorly defined.An extensive review of the literature has been performed, especially concerning indications, results and complications. Iodine-125 seeds have been implanted in astrocytomas I-III, glioblastomas, metastases and several other tumour entities. Outcome data given in the literature are summarized. Complications are rare in carefully selected patients.All in all, for highly selected patients with newly diagnosed or recurrent primary or metastatic tumours, this method provides encouraging survival rates with relatively low complication rates and a good quality of life.

Abstract
Glioblastoma is an aggressive form of brain cancer with a poor long-term prognosis. Treatment regimens for newly diagnosed disease range from surgical resection alone to surgery followed by radiotherapy with concurrent and adjuvant chemotherapy. Ongoing investigations are focused on optimization of chemotherapy by improving dosing and duration schedules and utilization of biomarkers for patient selection. Our understanding of glioblastoma tumor biology, the role of molecular signaling pathways, cellular repair mechanisms, and angiogenesis has increased greatly over the past few years, leading to the investigation of a variety of targeted therapies. In addition, advances in radiographic assessment have significantly impacted not only improvement in diagnosis, but interpretation of response to therapy. In order to effectively evaluate the clinical utility of new agents, as well as incorporate advances in radiographic assessment, changes to current clinical trial design need to be considered. This article reviews the care for newly diagnosed glioblastoma, as well as how recent findings might be incorporated into patient care.

Abstract
Local tumor control remains a significant challenge in patients with glioblastoma multiforme (GBM). Despite aggressive radiation therapy approaches, most recurrences are within the high-dose field, limiting the ability to safely re-irradiate recurrence using conventional techniques. Fractionated stereotactic radiosurgery (fSRS) is a technique whose properties make it useful for re-irradiation. We retrospectively reviewed the charts of 14 patients with recurrent GBM treated with salvage radiosurgery. Seven patients were male and seven were female with a median age of 58 (range: 39-76). All patients had prior cranial radiation therapy to a median dose of 60 Gy (58-69). There were 18 lesions treated with a median tumor volume of 6.97 cm3 (0.54-50.0 cm3). fSRS was delivered in 1-3 fractions to a median dose of 24 Gy (18-30 Gy). Median follow-up for the cohort was 8 months (3-22 months). On follow-up MRI, 8 of 18 lesions had a radiographic response. The median time-to-progression following primary irradiation was 8 months (1-28 months) while the median time-to-progression (TTP) following fSRS was 5 months (1-16 months). Median local control following re-irradiation was 5 months and actuarial local control was 21% at 1-year. Overall survival following primary irradiation was 79% at 12 months and 46% at 2 years. Overall survival following re-irradiation was 79% at 6 months and 30% at 1 year. No significant treatment-related toxicity was seen in follow-up. These results indicate that re-irradiation for recurrent GBM using fSRS is well-tolerated and can offer a benefit in terms of progression-free survival (PFS).

Abstract
The cell type and localization of vascular endothelial growth factor (VEGF)-producing cells in human radiation necrosis (RN) are investigated from a histopathological and immunohistochemical standpoint using clinical specimens. Eighteen surgical specimens of symptomatic RN in the brain were retrospectively reviewed. These cases included different original histological tumor types and were treated with different radiation modalities. Histological analyses were performed using hematoxylin and eosin (H&E) staining, and anti-VEGF and anti-hypoxia-inducible factor (HIF)-1α immunohistochemistry. H&E staining showed marked angiogenesis and reactive astrocytosis at the perinecrotic area. The most prominent vasculature in this area was identified as telangiectasis. Immunohistochemistry indicated that HIF-1α was expressed predominantly in the perinecrotic area and that a large majority of VEGF-expressing cells were reactive astrocytes intensively distributed in this area. VEGF produced by the reactive astrocytes localized mainly in the perinecrotic area might be a major cause of both angiogenesis and the subsequent perilesional edema typically found in RN of the brain. The benefits of anti-VEGF antibody (bevacizumab) treatment in RN may be that VEGF secretion from the perinecrotic tissue is inhibited and that surgery would remove this tissue; both of these benefits result in effective reduction of edema associated with RN.

Abstract
Greater than 50% of adults and approximately 100% of children who survive >6 months after fractionated partial or whole-brain radiotherapy develop cognitive impairments. Noninvasive methods are needed for detecting and tracking the radiation-induced brain injury associated with these impairments. Using magnetic resonance imaging, we sought to detect structural changes associated with brain injury in our rodent model of fractionated whole-brain irradiation (fWBI) induced cognitive impairment and to compare those changes with alterations that occur during the aging process. Middle aged rats were given a clinically relevant dose of fWBI (40 Gy: two 5 Gy fractions/week for 4 weeks) and scanned approximately 1 year post-irradiation to obtain whole-brain T2 and diffusion tensor images (DTI); control groups of sham-irradiated age-matched and young rats were also scanned. No gross structural changes were evident in the T2 structural images, and no detectable fWBI-induced DTI changes in fractional anisotropy (FA) were found in heavily myelinated white matter (corpus callosum, cingulum, and deep cortical white matter). However, significant fWBI-induced variability in FA distribution was present in the superficial parietal cortex due to an fWBI-induced decline in FA in the more anterior slices through parietal cortex. Young rats had significantly lower FA values relative to both groups of older rats, but only within the corpus callosum. These findings suggest that targets of the fWBI-induced change in this model may be the less myelinated or unmyelinated axons, extracellular matrix, or synaptic fields rather than heavily myelinated tracts.

Abstract
PURPOSE Salvage options for recurrent high-grade gliomas (HGGs) are limited by cumulative toxicity and limited efficacy despite advances in chemotherapeutic and radiotherapeutic techniques. Previous studies have reported encouraging survival results and favorable toxicity with fractionated stereotactic radiotherapy, and small studies have shown similar benefit using a shortened course of hypofractionated stereotactic radiation therapy (H-SRT). We sought to determine the efficacy and toxicity profile of H-SRT alone or in addition to repeat craniotomy or concomitant chemotherapy. PATIENTS AND METHODS Between 1994 and 2008, 147 patients with recurrent HGG were treated with H-SRT (median dose, 35 Gy in 3.5-Gy fractions). Cox regression models were used to analyze survival outcomes. Variables included age, surgery before H-SRT, time to first recurrence, reirradiation dose, inclusion of chemotherapy with H-SRT, and gross tumor volume (GTV). RESULTS Younger age (P = .001), smaller GTV (P = .025), and shorter time between diagnosis and recurrence (P = .034) were associated with improvement in survival from H-SRT. Doses of radiation > or = 35 Gy approached significance (P = .07). There was no significant benefit of surgical resection or chemotherapy in this population when analysis was controlled for other prognostic factors. CONCLUSION H-SRT was well tolerated and resulted in a median survival time of 11 months after H-SRT, independent of re-operation or concomitant chemotherapy. Patients who experienced recurrence within 6 months after initial treatment had an excellent response and should not be disqualified from H-SRT. This is the largest series to examine the efficacy and tolerability of H-SRT in recurrent HGG.

Abstract
Quality of life is an important area of clinical neurooncology that is increasingly relevant as survivorship increases and as patients experience potential morbidities associated with new therapies. This review of quality-of-life studies in the brain tumor population aims to summarize what is currently known about quality of life in patients with both low-grade and high-grade tumors and suggest how we may use this knowledge to direct future research. To date, reports on quality of life have been primarily qualitative and focused on specific symptoms such as fatigue, sleep disorders, and cognitive dysfunction, as well as some symptom clusters. However, the increasing interest in exploring quality of life as a primary end point for cancer therapy has established a need for prospective, controlled studies to assess baseline and serial quality-of-life parameters in brain tumor patients in order to plan and evaluate appropriate and timely interventions for their symptoms.

Abstract
PURPOSE To determine whether hippocampal neurons are lost 12 months after middle-aged rats received a fractionated course of whole-brain irradiation (WBI) that is expected to be biologically equivalent to the regimens used clinically in the treatment of brain tumors. METHODS AND MATERIALS Twelve-month-old Fischer 344 X Brown Norway male rats were divided into WBI and control (CON) groups (n = 6 per group). Anesthetized WBI rats received 45 Gy of (137)Cs gamma rays delivered as 9 5-Gy fractions twice per week for 4.5 weeks. Control rats were anesthetized but not irradiated. Twelve months after WBI completion, all rats were anesthetized and perfused with paraformaldehyde, and hippocampal sections were immunostained with the neuron-specific antibody NeuN. Using unbiased stereology, total neuron number and the volume of the neuronal and neuropil layers were determined in the dentate gyrus, CA3, and CA1 subregions of hippocampus. RESULTS No differences in tissue integrity or neuron distribution were observed between the WBI and CON groups. Moreover, quantitative analysis demonstrated that neither total neuron number nor the volume of neuronal or neuropil layers differed between the two groups for any subregion. CONCLUSIONS Impairment on a hippocampal-dependent learning and memory test occurs 1 year after fractionated WBI at middle age. The same WBI regimen, however, does not lead to a loss of neurons or a reduction in the volume of hippocampus.

Abstract
Management of Malignant Gliomas continues to be a challenge. We prospectively studied the role of adding weekly Paclitaxel to Fractionated Stereotactic Radiation Therapy (FSRT) in the treatment of Malignant Gliomas. Twenty-three Glioblastoma Multiforme and two Anaplastic Astrocytoma were studied. Patients received 46 Gy at 2 Gy/fraction followed by a boost utilizing FSRT at a fraction of 2.5 Gy for 8 fractions. Paclitaxel is delivered concomitantly at 150 mg/m(2) weekly for six cycles. Eighteen patients had pharmacokinetic assays of Paclitaxel levels. All patients were followed until death or for a maximum of 36 months. The overall survival of the whole group was 14 months. The median survival for RPA prognostic classes III, IV, V, and VI were 20, 14, 12, and 11 months. Higher survival (14 months) was noted in the subtherapeutic phenytoin level group compared to 10 months in the therapeutic group (P=0.271). No grade 4 CTCAE (version 3.0) toxicities were observed. Enhanced survival was demonstrated with gross tumor resection (20.8 months), KPS > or =80 (18.7 months) and age < or =60 years (27 months) as compared to subtotal resection or biopsy (12.1 months, P< 0.005), KPS < or =70 (10.8 months, P=0. 005) and older age > 60 (10.46 months, P=0.006), respectively. Our study suggests that: i) the use of weekly Paclitaxel and FSRT in Gliomas is well tolerated with a survival of 14 months; ii) the regimen resulted in improvement of survival of RPA classes IV, V, VI; and iii) the use of FSRT boost may be studied with other chemotherapeutic agents to see if superior results can be attained.

Abstract
Re-irradiation for recurrent gliomas has been discussed controversially in the past. This was mainly due to only marginal palliation while being associated with a high risk for side effects using conventional radiotherapy. With modern high-precision radiotherapy re-irradiation has become a more wide-spread, effective and well-tolerated treatment option. Besides external beam radiotherapy, a number of invasive and/or intraoperative radiation techniques have been evaluated in patients with recurrent gliomas. The present article is a review on the available methods in radiation oncology and summarizes results with respect to outcome and side effects in comparison to clinical results after neurosurgical resection or different chemotherapeutic approaches.

Abstract
Stereotactic radiosurgery is a neurosurgical modality in which a target lesion can be irradiated while sparing normal brain tissue. In some respects, brain metastasis is well suited for radiosurgery, as metastatic lesions tend to be small and well circumscribed and displace (but do not infiltrate) normal brain tissue, facilitating the delivery of radiation. Advances in stereotactic radiosurgical planning, such as blocking patterns and beam shaping, have allowed further targeting of discrete lesions while minimizing the effect of radiation toxicity on the central nervous system. In this paper the authors review the radiobiology of brain metastases and stereotactic radiosurgical approaches that can be used to treat these tumors safely.

Abstract
PURPOSE To describe the co-occurring symptoms (depression, fatigue, pain, sleep disturbance, and cognitive impairment), quality of life (QoL), and functional status in patients with high-grade glioma. DESIGN Correlational, descriptive study of 73 participants with high-grade glioma in the U.S. METHODS Nine brief measures were obtained with a mailed survey. Participants were recruited from the online message board of The Healing Exchange BRAIN TRUST, a nonprofit organization dedicated to improving quality of life for people with brain tumors. FINDINGS Two symptom cluster models were examined. Four co-occurring symptoms were significantly correlated with each other and explained 29% of the variance in QoL: depression, fatigue, sleep disturbance, and cognitive impairment. Depression, fatigue, sleep disturbance, cognitive impairment, and pain were significantly correlated with each other and explained 62% of the variance in functional status. CONCLUSIONS The interrelationships of the symptoms examined in this study and their relationships with QoL and functional status meet the criteria for defining a symptom cluster. The differences in the models of QoL and functional status indicates that symptom clusters may have unique characteristics in patients with gliomas.

GliaSite brachytherapy boost as part of initial treatment of glioblastoma multiforme: a retrospective multi-institutional pilot study. Int J Radiat Oncol Biol Phys 2007; 68:159-65.

Abstract
PURPOSE To report on a retrospective analysis of the cumulative experience from eight institutions using the GliaSite Radiotherapy System as a brachytherapy boost in the initial management of glioblastoma multiforme. METHODS AND MATERIALS Eight institutions provided data on 20 patients with histologically proven glioblastoma multiforme with a median age of 59 years (range, 39-76) and median Karnofsky performance scale of 80 (range, 50-100). After maximal surgical debulking, patients were treated with GliaSite brachytherapy to a median dose of 50 Gy, followed by external beam radiotherapy to a median dose of 60 Gy (range, 46-60 Gy), for a cumulative dose escalation of 110 Gy (range, 84-130 Gy). RESULTS The average survival for this study population was 11.4 months (range, 4-29). When the patients' survival was compared with that of historical controls according to their Radiation Therapy Oncology Group recursive partitioning analysis class, the average survival was increased by 3 months (95% confidence interval, 0.23-4.9) corresponding to a 43% increase (p = 0.033). Three patients (14%) experienced Radiation Therapy Oncology Group Grade 3 central nervous system toxicity. Of the treatment failures, 50% were >2 cm from the edge of the balloon. CONCLUSION The results of this analysis have demonstrated that dose escalation (>100 Gy) with GliaSite is well tolerated and associated with minimal toxicity. Local control improved with the use of GliaSite brachytherapy. The putative survival advantage seen in this study needs to be interpreted with caution; nevertheless, the data provide sufficient justification to investigate the potential role of radiation dose escalation in conjunction with GliaSite in the initial treatment of glioblastoma multiforme.

Abstract
Strategies for the treatment of childhood cancer have changed considerably during the last 50 years and have led to dramatic improvements in long-term survival. Despite these accomplishments, CNS tumors remain the leading cause of death in pediatric oncology. Astrocytic tumors form the most common histologic group among childhood brain tumors. They are a heterogeneous group that from a practical therapeutic point of view can be subdivided into low-grade astrocytomas (LGA), optic pathway gliomas (OPG), high-grade astrocytomas (HGA), and brainstem gliomas (BSG). This article focuses on the practical application of treatments that lead to long-term survival, improved quality of life, and reduced long-term complications. Improvement in therapy has led to better outcomes for patients with LGA and OPG. Careful follow-up without any treatment is indicated for a small percentage of patients diagnosed with LGA with an indolent course including children with neurofibromatosis type 1 (NF1). Surgery is the main recommended treatment for children with resectable LGA. Radiation therapy is generally recommended for children with progressive LGA, or after failure of chemotherapy, accomplishing tumor control at 10 years in over 60% of patients. Cytotoxic chemotherapy is usually reserved for children who have had treatment failure with surgery and radiation therapy. It is also offered for children who are too young to be treated with radiation or to defer or avoid radiotherapy. Carboplatin and vincristine achieve 5% complete and 28% partial responses but the use of vincristine is criticized due to poor penetration of the CNS. A regimen of tioguanine, procarbazine, mitolactol, lomustine, and vincristine is frequently administered as an alternative to carboplatin and vincristine in LGA. The introduction of temozolomide has allowed better responses, including a 24% complete response rate compared with 0-5% complete response rates with the previous regimens. OPG are usually histologically LGA, and are treated with similar chemotherapy regimens. OPG is the most common type of brain tumor associated with NF1. Tumor growth in some of these patients is slow with no treatment recommended for an extended period of time. The prognosis for children with the remaining types of astrocytomas remains poor. Surgical resection is typically the first step in the treatment of HGA followed in older children by radiation therapy. The data regarding chemotherapy are mixed. Combination chemotherapy before or after radiation, including cisplatin, carmustine, cyclophosphamide, and vincristine or carboplatin, ifosfamide, cyclophosphamide, and etoposide has provided disappointing results. Clinical trials with temozolomide and agents directed against single targets have not shown substantially better results, but it is hoped that currently conducted studies will provide better outcomes. Diffuse intrinsic BSG are among the most difficult-to-treat brain tumors. Surgical treatment is not recommended for diffuse intrinsic BSG and standard radiation therapy is typically given in children aged >3 years. None of the numerous chemotherapy regimens, including temozolomide, has provided a significant response rate or an improvement in survival. It is expected that newer agents affecting multiple targets such as AEE-788 and antineoplastons, and combinations of single-targeted agents with chemotherapy will provide better results. Careful evaluation of histology, location of the tumor, patient age, and consideration of treatment-related morbidity play an important part in selecting between clinical observation, surgery, radiation, chemotherapy, or investigational agents. The goals of treatment for astrocytic tumors should extend well beyond objective responses and increased survival. Improvement of quality of life is an equally important objective of treatment. Radiation therapy and chemotherapy result in serious late toxicities.

Abstract
Primary brain tumors are associated with a poor prognosis and recognized impact on physical and neurologic function. In an effort to improve poor prognosis, novel therapeutic approaches have been pursued. The impact of therapy on function has not been fully evaluated in the past, with clinical trials focused on traditional survival endpoints. Therapies to date have been associated with incremental improvements in survival that may not have been associated with improvement in functional status. Methods for evaluating this impact include health-related quality of life symptom burden and evaluation of neurocognitive function. Each approach has associated benefits and limitations based on the type of treatment and the potential impact on functional status. An essential component of trial design evaluating functional endpoints is the development of clear hypotheses, specific aims, and predefined metrics of functional change related to each measure. This paper reviews these three approaches and discusses their potential use in evaluation of therapies for patients with primary brain tumors.

Abstract
This study explored the use of complementary and alternative medicine (CAM) approaches and their relationship with demographic and disease characteristics and quality of life (QOL) in the primary brain tumor (PBT) population. One hundred one PBT patients were enrolled in this study. The results showed that 34% of patients reported using CAM. Forty-one percent reported using more than one type of CAM. The average cost of each CAM used per month was 69 dollars, with 20% of patients spending more than 100 dollars per month. The majority (74%) reported that their physicians were unaware of their use of CAM. Data analysis found a higher performance status to be the only factor significantly related to use of CAM therapy (P < 0.005). There was no difference in patient report of QOL between users and nonusers of CAM therapies. The high number of patients who do not report CAM use has potential implications for evaluation of symptoms and response to therapy in this population. This may be especially relevant in those patients with higher functional status participating in clinical trials.

Abstract
OBJECTIVE To evaluate intravitreal triamcinolone acetonide for patients with visually symptomatic acute radiation-induced papillopathy. METHODS In a prospective, nonrandomized, single-center case series, intravitreal triamcinolone acetonide (4 mg/0.1 mL) was injected through the pars plana using sterile technique in 9 patients with radiation papillopathy after plaque radiotherapy for choroidal melanoma. Status of radiation papillopathy and final visual acuity were the main outcome measures. RESULTS At the time of diagnosis of the choroidal melanoma, visual acuity was 20/20 to 20/40 (n = 6), 20/60 (n = 2), and 20/100 (n = 1). The mean radiation dose to the optic disk was 6,175 cGy (median, 5,994 cGy; range, 3,571-12,760 cGy). Radiation papillopathy developed a mean of 18 months (median, 17 months; range, 6-33 months) after plaque radiotherapy. In all cases, the choroidal melanoma was regressed, and there was no retinal detachment or neovascularization of the retina, optic disk, or iris. Concomitant radiation maculopathy was found in 8 eyes manifesting as macular edema (n = 8), intraretinal dot hemorrhages (n = 6), intraretinal exudation (n = 6), or nerve fiber layer infarction (n = 3). The radiation papillopathy findings included optic disk hyperemia (n = 9), edema (n = 9), and circumpapillary hemorrhage (n = 8). At the time of diagnosis of radiation papillopathy, visual acuity was 20/70 (n = 1), 20/100 (n = 4), 20/200 (n = 1), and counting fingers (n = 3). At 1 week after injection of triamcinolone acetonide, visual acuity improvement was found in seven patients, and resolution of optic disk hyperemia and edema was noted for four and three patients, respectively. At a mean follow-up of 11 months (median, 9 months; range, 6-19 months), visual acuity was stable or improved in 7 patients, and resolution of optic disk hyperemia and edema was found in all 9 patients. The mean time to improvement in visual acuity by > or =2 lines was 3 weeks (median, 1 week; range, 1-12 weeks). The mean time to complete resolution of radiation papillopathy was 4 months. The two patients with worse final visual acuity also had macular hole and central retinal vein obstruction. The only complication of this therapy was possibly related cataract in three patients. CONCLUSION During short-term follow-up, acute radiation-induced papillopathy appears to respond rapidly to intravitreal triamcinolone acetonide injection with resolution of optic disk hyperemia and edema and modest return of visual acuity. The long-term effects remain unknown.

Abstract
Abstract
OBJECTIVE:
To review the cumulative experience of 10 institutions in treating recurrent malignant gliomas with the brachytherapy device, GliaSite Radiation Therapy System.
METHODS:
The patient population consisted of 95 patients with recurrent grade 3 or 4 gliomas, a median age of 51 years, and a median Karnofsky performance status score of 80. All patients had previously undergone resection and had received external beam radiotherapy as part of their initial treatment. After recurrence, each patient underwent maximal surgical debulking of their recurrent lesion and placement of an expandable balloon catheter (GliaSite) in the tumor cavity. The balloon was afterloaded with liquid 125I (Iotrex) to deliver a median dose of 60 Gy to an average depth of 1 cm with a median dose rate of 52.3 Gy/hr. Patients were carefully followed with serial magnetic resonance imaging and monthly examinations for tumor progression, side effects, and survival.
RESULTS:
The median survival for all patients, measured from date of GliaSite placement, was 36.3 weeks with an estimated 1 year survival of 31.1%. The median survival was 35.9 weeks for patients with an initial diagnosis of glioblastoma multiforme and 43.6 weeks for those with non- glioblastoma multiforme malignant gliomas. Analysis of the influence of various individual prognostic factors on patient survival demonstrated that only Karnofsky performance status significantly predicted for improved survival. There were three cases of pathologically documented radiation necrosis.
CONCLUSION:
Reirradiation of malignant gliomas with the GliaSite Radiation Therapy System after reresection seems to provide a modest survival benefit above what would be expected from surgery alone. This report not only confirms the initial results of the feasibility study but provides evidence that similar outcomes can be obtained outside of a clinical trial.

Abstract
PURPOSE To investigate radiation necrosis in patients treated for glioma in terms of incidence, outcomes, predictive and prognostic factors. METHODS AND MATERIALS Records were reviewed for 426 patients followed up until death or for at least 3 years. Logistic regression analysis was performed to identify predictive and prognostic factors. Multivariate survival analysis was conducted using Cox proportional hazards regression. Separate analyses were performed for the subset of 352 patients who received a biologically effective dose (BED) > or =85.5 Gy2 (> or =45 Gy/25 fractions) who were at highest risk for radionecrosis. RESULTS Twenty-one patients developed radionecrosis (4.9%). Actuarial incidence plateaued at 13.3% after 3 years. In the high-risk subset, radiation parameters confirmed as risk factors included total dose (p < 0.001), BED (p < 0.005), neuret (p < 0.001), fraction size (p = 0.028), and the product of total dose and fraction size (p = 0.001). No patient receiving a BED <96 Gy2 developed radionecrosis. Subsequent chemotherapy significantly increased the risk of cerebral necrosis (p = 0.001) even when adjusted for BED (odds ratio [OR], 5.8; 95% confidence interval [CI], 1.6-20.3) or length of follow-up (OR, 5.4; 95% CI, 1.5-19.3). Concurrent use of valproate appeared to delay the onset of necrosis (p = 0.013). The development of radionecrosis did not affect survival (p = 0.09). CONCLUSIONS Cerebral necrosis is unlikely at doses below 50 Gy in 25 fractions. The risk increases significantly with increasing radiation dose, fraction size, and the subsequent administration of chemotherapy.

Abstract
OBJECTIVE Adjuvant systemic chemotherapy increases survival of primary malignant glioma patients beyond 12-18 months. The only interstitial chemotherapy treatment approved for malignant glioma is Gliadel wafer containing carmustine (BCNU) placed in the resection cavity at surgery. Analysis of a large trial by Westphal and colleagues (n = 240) showed a 29% risk reduction (P = 0.03) in the BCNU wafer-treated group over the course of the 30-month trial. Long-term follow-up of these patients was undertaken to determine the survival benefit at 2 and 3 years. METHODS Survival proportions for the placebo and treatment groups over the 56-month study were estimated by the Kaplan-Meier method. Multiple-regression analyses using the Cox proportional hazards model included prognostic factors of age, KPS, and tumor type. A secondary analysis was conducted for 207 GBM patients. RESULTS Of the 59 patients available for long-term follow-up, 11 were alive at 56 months: 9 had received BCNU wafers and 2 had received placebo wafers. Median survival of patients treated with BCNU wafers was 13.8 months vs 11.6 months in placebo-treated patients (P = 0.017) with a hazard ratio of 0.73 (P = 0.018), representing a 27% significant risk reduction. This survival advantage was maintained at 1, 2, and 3 years and was statistically significant (P = 0.01) at 3 years. Two of 207 GBM patients remained alive at the end of the follow-up period, both in the BCNU wafer-treated group. CONCLUSION Malignant glioma patients treated with BCNU wafers at the time of initial surgery in combination with radiation therapy demonstrated a survival advantage at 2 and 3 years follow-up compared with placebo.

Abstract
Purpose To evaluate the efficacy of fractionated stereotactic radiotherapy (FSRT) performed as reirradiation in 172 patients with recurrent low- and high-grade gliomas. Patients and Methods Between 1990 and 2004, 172 patients with recurrent gliomas were treated with FSRT as reirradiation in a single institution. Seventy-one patients suffered from WHO grade 2 gliomas. WHO grade 3 gliomas were diagnosed in 42 patients, and 59 patients were diagnosed with glioblastoma multiforme (GBM). The median time between primary radiotherapy and reirradiation was 10 months for GBM, 32 months for WHO grade 3 tumors, and 48 months for grade 2 astrocytomas. FSRT was performed with a median dose of 36 Gy in a median fractionation of 5 × 2 Gy/wk. Results Median overall survival after primary diagnosis was 21 months for patients with GBM, 50 months for patients with WHO grade 3 gliomas, and 111 months for patients with WHO grade 2 gliomas. Histologic grading was the strongest predictor for overall survival, together with the extent of neurosurgical resection and age at primary diagnosis. Median survival after reirradiation was 8 months for patients with GBM, 16 months for patients with grade 3 tumors, and 22 months for patients with low-grade gliomas. Only time to progression and histology were significant in influencing survival after reirradiation. Progression-free survival after FSRT was 5 months for GBM, 8 months for WHO grade 3 tumors, and 12 months for low-grade gliomas. Conclusion FSRT is well tolerated and may be effective in patients with recurrent gliomas. Prospective studies are warranted for further evaluation.

Abstract
BACKGROUND This article describes the results of a study of stereotactic radiosurgery (SRS) in the treatment of patients with recurrent malignant glioma. METHODS Thirty-two patients with recurrent glioblastoma multiforme (GBM) were treated for 36 lesions with SRS from 1993 to 2001. Nineteen patients were male and 13 were female. The median age at primary diagnosis of the tumor was 56 years (range, 33-76 yrs). At the time of initial diagnosis a total neurosurgical resection was performed in 7, a subtotal resection in 21, and a biopsy in 4 patients. Histology evaluations revealed glioblastoma multiforme (WHO Grade IV) in all 32 patients. In all patients radiotherapy was performed as the first-line therapy, applied as fractionated external beam radiotherapy. The median interval between primary irradiation and reirradiation was 10 months. The median dose applied was 15 Gy (range, 10-20 Gy) prescribed to the 80% isodose line that encompassed the target volume. No concomitant chemotherapy was applied. RESULTS Treatment was well tolerated by all patients. No acute toxicities > CTC Grade II occurred. No severe long-term toxicities including radionecrosis were observed. The median follow-up time was 13 months (range, 1-89 mo). All patients died of tumor progression during follow-up. The median overall survival from primary diagnosis of the tumor was 22 months (range, 9-133 mo). The survival rate at 1 year was 90%, and 49% and 26% at 2 and 3 years, respectively. Median overall survival after SRS was 10 months. At 6 and 12 months after SRS, survival rates were 72% and 28%, respectively. Median progression-free survival after SRS was 7 months. CONCLUSIONS SRS offers effective treatment as a salvage therapy for a subgroup of patients with smaller lesions of recurrent GBM.

Abstract
Whole-brain irradiation of animals and humans has been reported to lead to late delayed structural (vascular damage, demyelination, white matter necrosis) and functional (cognitive impairment) alterations. However, most of the experimental data on late delayed radiation-induced brain injury have been generated with large single doses or short fractionation schemes that may provide a less accurate indication of the events that occur after clinical whole-brain radiotherapy. The pilot study reported here investigates cerebral vascular pathology in male Fischer 344 rats after whole-brain irradiation with a fractionated total dose of 137Cs gamma rays that is expected to be biologically similar to that given to brain tumor patients. The brains of young adult rats (4 months old) were irradiated with a total dose of 40 Gy, given as eight 5-Gy fractions twice per week for 4 weeks. Brain capillary and arteriole pathology was studied using an alkaline phosphatase enzyme histochemistry method; vessel density and length were quantified using a stereology method with computerized image processing and analysis. Vessel density and length were unchanged 24 h after the last dose, but at 10 weeks postirradiation, both were substantially decreased. After 20 weeks, the rate of decline in the vessel density and length in irradiated rats was similar to that in unirradiated age-matched controls. No gross gliosis or demyelination was observed 12 months postirradiation using conventional histopathology techniques. We suggest that the early (10-week) and persistent vascular damage that occurs after a prolonged whole-brain irradiation fractionation scheme may play an important role in the development of late delayed radiation-induced brain injury.

Abstract
PURPOSE In this study, we assess the efficacy of GliaSite brachytherapy in the treatment of patients with recurrent glioblastoma multiforme (GBM). METHODS AND MATERIALS Between 1999 and 2004, 24 patients with recurrent glioblastoma multiforme were treated with the GliaSite Radiation Therapy System (RTS). The GliaSite is an inflatable balloon catheter that is placed in the resection cavity at the time of surgical resection. Low-dose-rate radiation is then delivered locally by temporarily inflating the balloon with an aqueous solution of organically bound (125)I (Iotrex [sodium 3-((125)I)-iodo-4-hydroxybenzenesulfonate]). Patients at the Johns Hopkins Hospital with recurrent GBM, who were previously treated with surgery and external beam radiotherapy, underwent surgical resection followed by GliaSite balloon implantation. Subsequently, the patients received radiation therapy using the GliaSite to a mean dose of 53.1 Gy. Ten patients were male, and 14 patients were female. The mean age was 48.1 years. All patients had pathologically confirmed recurrent GBM. The median Karnofsky performance status (KPS) was 80. Median follow-up time was 21.8 months. RESULTS At the time of analysis, 18 patients (75%) had died; 6 patients (25%) were alive. Median survival from diagnosis for all patients was 23.3 months. Median survival after GliaSite brachytherapy was 9.1 months. Patients with a KPS > or =70 had a median survival of 9.3 months, whereas patients with a KPS <70 had a median survival of 3.1 months (p < 0.003). Survival was not significantly different between patients receiving 45 Gy and patients receiving a dose greater than 45 Gy. Acute side effects were minor, consisting of mild nausea and/or headache. One patient developed a wound infection. No incidents of meningitis were observed. Late sequelae were rare, but 2 incidents of symptomatic radiation necrosis were observed. One patient developed transient expressive aphasia. CONCLUSIONS GliaSite radiotherapy confers a prolongation of survival in patients with recurrent glioblastoma multiforme compared to historical controls with recurrent GBM. GliaSite therapy leads to a favorable survival outcome of 9.3 months in patients with KPS > or =70, but only 3.1 months in patients with KPS <70. Favorable survival is observed for patients within each recursive partitioning analysis class. Treatment with GliaSite is safe and generally well tolerated. Additional data are needed to fully assess the therapeutic benefit of GliaSite brachytherapy for recurrent GBM.

Abstract
This study reports the initial experience at the University of California San Francisco (UCSF) with tumor resection and permanent, low-activity iodine 125 (125I) brachytherapy in patients with progressive or recurrent glioblastoma multiforme (GM) and compares these results to those of similar patients treated previously at UCSF with temporary brachytherapy without tumor resection. Thirty-eight patients with progressive or recurrent GM were treated at UCSF with repeat craniotomy, tumor resection, and permanent, low-activity 125I brachytherapy between June 1997 and May 1998. Selection criteria were Karnofsky performance score > or =60, unifocal, contrast-enhancing, well-circumscribed progressive or recurrent GM that was judged to be completely resectable, and no evidence of leptomeningeal or subependymal spread. The median brachytherapy dose 5 mm exterior to the resection cavity was 300 Gy (range, 150-500 Gy). One patient was excluded from analysis. Median survival was 52 weeks from the date of brachytherapy. Age, Karnofsky performance score, and preimplant tumor volume were all statistically significant on univariate analyses. Multivariate analysis for survival showed only age to be significant. Median time to progression was 16 weeks. Both univariate and multivariate analysis of freedom from progression showed only preoperative tumor volume to be significant. Comparison to temporary brachytherapy patients showed no apparent difference in survival time. Chronic steroid requirements were low in patients with minimal postoperative residual tumor. We conclude that permanent 125I brachytherapy for recurrent or progressive GM is well tolerated. Survival time was comparable to that of a similar group of patients treated with temporary brachytherapy.

Abstract
AIMS To determine local control and overall survival rates of 14 patients treated for a grade III or IV glioma relapsing in a previously irradiated area and re-irradiated by stereotactic radiosurgery. PATIENTS AND METHODS From January 1997 to October 2001, 14 patients (median age 52 Years, age range 49-58 Years, Karnofski performance score 80 to 100) received radiosurgery for a relapse of grade III (3 patients) and or grade IV (10 patients) malignant gliomas. Before relapse, all patients had undergone surgery and had been given with a classical radiation protocol. Median maximum diameter and Volume of the tumors were 38.5mm (24-86mm) and 7cm3 (2-35cm3), respectively. RESULTS Median maximal dose at the isocenter and median minimal dose at the periphery of the lesion were 21Gy (16-38Gy) and 13Gy (9-17Gy), respectively. Mean follow-up was 8.5 Months (1-29). Median overall survival was 11.6 Months; 6-Month, 1- and 2-Year overall survival rates were 85p.100, 36p.100 and 12p.100, respectively. At univariate analysis, only histological grade was a significant prognostic factor of overall survival (p=0.03). Median disease-free survival was 8.2 Months while 6-Month and 1-Year disease-free survival rates were 69p.100 and 14p.100, respectively. According to univariate analysis, histological grade (p=0.033) and minimal dose delivered at the margin of the target Volume (p=0.02) were prognostic factors for disease-free survival. Two patients developed a symptomatic radionecrosis. CONCLUSION Radiosurgery of relapsed primitive high-grade brain tumors is efficient and overall survival rates were encouraging.
