Abstract
BACKGROUND AND OBJECTIVES Spinal cord metastasis arising from an intracranial glioblastoma is a rare and late event during the natural course of the disease. These pathological entities remain poorly characterized. This study aimed to identify and investigate the timeline, clinical and imaging findings, and prognostic factors of spinal cord metastasis from a glioblastoma. METHODS Consecutive histopathological cases of spinal cord metastasis from glioblastomas in adults entered in the French nationwide database between January 2004 and 2016 were screened. RESULTS Overall, 14 adult patients with a brain glioblastoma (median age 55.2 years) and harboring a spinal cord metastasis were included. The median overall survival as 16.0 months (range, 9.8-22.2). The median spinal cord Metastasis Free Survival (time interval between the glioblastoma diagnosis and the spinal cord metastasis diagnosis) was 13.6 months (range, 0.0-27.9). The occurrence of a spinal cord metastasis diagnosis greatly impacted neurological status: 57.2% of patients were not ambulatory, which contributed to dramatically decreased Karnofsky Performance Status (KPS) scores (12/14, 85.7% with a KPS score ≤ 70). The median overall survival following spinal cord metastasis was 3.3 months (range, 1.3-5.3). Patients with a cerebral ventricle effraction during the initial brain surgery had a shorter spinal cord Metastasis Free Survival (6.6 vs 18.3 months, p = 0.023). Out of the 14 patients, eleven (78.6%) had a brain IDH-wildtype glioblastoma. CONCLUSIONS Spinal cord metastasis from a brain IDH-wildtype glioblastoma has a poor prognosis. Spinal MRI can be proposed during the follow-up of glioblastoma patients especially those who have benefited from cerebral surgical resection with opening of the cerebral ventricles.

Abstract
Aggressive primary brain tumors (APBT) glioblastoma multiforme and grade IV astrocytoma are treated with multimodality treatments that include surgery to remove as much tumor as possible without sacrificing neurological function followed by radiation therapy and chemotherapy usually temozolomide. Survivals in adults are in the range of 8–16 months. The addition of a ketogenic diet (KD) to rodents with transplanted brain tumors increased survival in nine of 11 animals to over 299 days compared to survival in untreated controls of 33 days and radiation only controls of 38 days. We treated humans with APBT with standard of care neurosurgery immediately followed by 6 weeks of an adjuvant ketogenic diet concurrent with radiation therapy and temozolomide. Twice daily measurements of blood ketones and glucose were recorded and the patients' diet was modified toward the goal of maintaining blood ketone levels approaching 3 mM. Of the nine patients who completed the protocol three younger patients age 32, 28, and 22 at enrollment are alive and employed with clinically stable disease and brain images 74, 58, and 52 months since diagnosis. All the six older patients mean age 55 have died with disease progression detected on average 8 months after Dx. In conclusion: 1. It is possible to implement and maintain dietary induced ketosis in patients with APBT; 2. The longer survivals observed in younger patients treated with KD need to be confirmed in larger studies that should be focused on younger patients possibly under age 40.

Abstract
PURPOSE The reasons why a specific subset of glioblastoma (GBM) patients survive longer than others is still unclear. This study analyzed a cohort of long-term and very-long-term GBM survivors to determine which genetic alterations or patient's characteristics influence survival time. METHODS We retrospectively reviewed a cohort of GBM patients treated at our institution over the last 20 years, stratifying patients in three groups: those with a survival time ≥ 36 months and < 120 months (LTS), ≥120 months (VLTS), and < 36 months, respectively. Clinical (age, sex, focality, resection degree, Karnofsky performance status), and immunohistochemical and molecular data (Ki-67 expression and multiple genes alterations) were collected. We then utilized principal component analysis, logistic regression, and Cox proportional hazard models to identify those variables associated with survival. RESULTS Younger age at presentation (HR = 0.36, 95% CI 0.21-0.67, p = .001), and MGMT promoter [(MGMTp), methylated, HR = 0.57, CI 0.34-0.96, p = .034) were associated with higher odds of VLTS survival. The multivariate analysis showed how the combination of younger age (< 50 years), Ki-67 < 10%, and the coexistence of TERTp not mutated, MGMTp methylated, and IDH1/2 mutated in the same patient are also associated with higher odds of survival (HR = 0.10, CI 0.01-0.74, p = .025). CONCLUSIONS We confirmed younger age at presentation and MGMTp methylation as the only independent factors associated with VLTS. The exceptional survival of our VLTS patients is probably associated with different, still understudied, gene mutations, or with the coexistence of multiple factors.

Abstract
Although glioblastoma (GBM) is a fatal primary brain cancer with short median survival of 15 months, a small number of patients survive >5 years after diagnosis; they are known as extreme survivors (ES). Because of their rarity, very little is known about what differentiates these outliers from other patients with GBM. For the purpose of identifying unknown drivers of extreme survivorship in GBM, the ENDURES consortium (ENvironmental Dynamics Underlying Responsive Extreme Survivors of GBM) was developed. This consortium is a multicenter collaborative network of investigators focused on the integration of multiple types of clinical data and the creation of patient-specific models of tumor growth informed by radiographic and histologic parameters. Leveraging our combined resources, the goals of the ENDURES consortium are 2-fold: (1) to build a curated, searchable, multilayered repository housing clinical and outcome data on a large cohort of ES patients with GBM; and (2) to leverage the ENDURES repository for new insights into tumor behavior and novel targets for prolonging survival for all patients with GBM. In this article, the authors review the available literature and discuss what is already known about ES. The authors then describe the creation of their consortium and some preliminary results.

Abstract
Glioblastoma (GBM) is among the most deadly neoplasms associated with one of the worst 5-year overall survival (OS) rates among all human cancers. The aim of this systematic review is to present all cases with OS of a decade or more and to perform a descriptive analysis of the group. This systematic review was conducted in compliance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. A comprehensive search for relevant articles was performed on PubMed, Embase and Google Scholar for a period until June 10, 2016, using the following search words: glioblastoma multiforme, glioblastoma, GBM, long-term survival/survivors. Reports containing cases with the long-term survival of 10 years or longer were included in the review. The search produced 36 studies with 162 cases published in the years 1950-2014. The rate of long survivors in the cohort studied was established 0.76%. Mean age at diagnosis, OS and PFS were 31.1 ± 11.1, 15.9 ± 6.3, 11.9 ± 5.6 years respectively. Total and subtotal resections were found in 82 and 58 patients respectively. Nine cases received a biopsy alone. No statistical differences were found in a comparison of PFS, OS and age between total and subtotal resection groups. A regression analysis showed a significant correlation between PFS and OS, with an inverse relationship stated between age at diagnosis and OS. The 10-year survival rate in the cohort studied with GBM was estimated 0.71%. OS was positively correlated with the length of PFS and inversely related with age at diagnosis.

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
UNLABELLED The median overall survival of glioblastoma patients is about 15 months. Only a small number of patients survive 3 years. The factors of a favorable prognosis for the 'longevity phenomenon' in glioblastoma patients are not fully understood. OBJECTIVE to determine the occurrence rate of long-living patients with glioblastomas, identify clinical predictors of a favorable prognosis, and identify the presence and prognostic significance of an IDH1 mutation. MATERIAL AND METHODS Among 1494 patients operated on for glioblastoma at the Burdenko Neurosurgical Institute from 2007 to 2012, there were 84 (5.6%) patients who lived more than 3 years after primary surgery. In all the cases, histological specimens were reviewed, and immunohistochemical detection of a mutant IDH1 protein was performed. Overall survival was calculated from the time of first surgery to the date of the last consultation or death, and the recurrence-free period was calculated from the time of first surgery to MRI-verified tumor progression. RESULTS The median age of long-living patients with glioblastoma was 45 years (19-65 years). All tumors were located supratentorially. The median Karnofsky performance status score at the time of surgery was 80 (range, 70-100). All patients underwent microsurgical resection of the tumor, followed by chemoradiotherapy. The median recurrence-free period was 36 months (5-98 months). Overall survival of 48, 60, and 84 months was achieved in 23, 15 and 6% of patients, respectively. Among 49 specimens available for the IDH1 analysis, 14 (28.6%) specimens had a mutant protein. There was no significant difference in survival rates in patients with positive and negative results for IDH1 (44.1 vs. 40.8 months; p>0.05). CONCLUSION The significance of various factors that may be predictors of a favorable course of the disease is discussed in the literature. This work is the first part of analysis of prognostically significant factors positively affecting overall survival of glioblastoma patients. In our series, the predictors of a favorable prognosis for long-living patients with the verified diagnosis of glioblastoma were as follows: young age, the supratentorial location of the tumor, a high Karnofsky score before surgery, and tumor resection. In our series, we used immunohistochemical tests and found no prognostic significance of the IDH1 gene mutation; further analysis will require application of direct sequencing. We plan to study other morphological and molecular genetic features of tumors, which explain prolonged survival of glioblastoma patients, as well as the role of various types of combined chemoradiation treatment.

Abstract
BACKGROUND A very small proportion of patients diagnosed with glioblastoma (GBM) survive more than 3 years. Isocitrate dehydrogenase 1 or 2 (IDH1/2) mutations define a small subgroup of GBM patients with favourable prognosis. However, it remains controversial whether long-term survivors (LTS) are found among those IDH1/2 mutated patients. METHODS We retrospectively analyzed 207 GBM patients followed at Lariboisière Hospital (Paris) between 2005 and 2010. Clinical parameters were obtained from medical records. Mutations of IDH1/2 were analyzed in these patients, by immunohistochemistry for the R132H mutation of IDH1 and by high-resolution melting-curve analysis, followed by Sanger sequencing for IDH1 and IDH2 exon 4 mutations. Mutation rates in LTS and non-LTS groups were compared by Chi square Pearson test. RESULTS Seventeen patients with survival >3 years were identified (8.2% of the total series). The median overall survival in long-term survivors was 4.6 years. Subgroup analysis found that the median age at diagnosis was significantly higher for non long-term survivors (non-LTS) compared to LTS (60 versus 51 years, p <0.03). The difference in the rate of IDH mutation between non-LTS and LTS was statistically not significant (1.16% versus 5.9%, p = 0.144). Among LTS, 10 out of 16 tumors presented a methylation of MGMT promoter. CONCLUSIONS This study confirms that long-term survival in GBM patients is if at all only weakly correlated to IDH-mutation.

Abstract
Long-term survival is an often used, yet poorly defined, concept in the study of glioblastoma multiforme (GBM). This study suggests a method to define a time-point for long-term survival in patients with GBM. Data for this study were obtained from the Surveillance, Epidemiology and End-Results database, which was limited to the most recent data using the period approach. Relative survival measures were used and modelled using piecewise constant hazards to describe the survival profile of long-term survivors of GBM. For patients with GBM, the first quarter of the second year (5th quarter) post-diagnosis is considered to be the peak incidence of mortality with an excess hazard ratio of 7.58 (95% confidence interval=6.54, 8.78) and the risk of death due to GBM decreases to half of its rate at 2.5 years post-diagnosis. The 2.5-year cumulative relative survival (CRS) for all patients is approximately 8%, with a CRS of approximately 2% at 10 years. Using the definition of long-term survival suggested here, the results indicate that long-term survivors are patients who survive at least 2.5 years post-diagnosis. The most likely time period for patients with GBM to die is the 5th quarter post-diagnosis.

Abstract
Glioblastoma is the most frequent and most aggressive primary brain tumor. Primary and secondary glioblastomas develop through different genetic pathways. The aim of this study was to determinate the genetic and clinical features of primary glioblastoma in Moroccan patients. The blood and tumor samples were obtained from a group of 34 Moroccan patients affected with primary glioblastoma. The tumors were investigated for TP53, IDH1, and IDH2 mutations using PCR sequencing analysis. Clinicopathological data showed that the mean age at diagnosis of patients was 50.06 years, the sex ratio was 11 F/23 M, and the median of Karnofsky performance score was 60. About 18 % of patients were initially treated by total tumor resection, 41 % by subtotal, and 38 % by partial resection, but biopsy was performed for a single patient (3 %). Twenty-five patients (74 %) received radiotherapy. In addition, the median survival of the all patients was 13 months following diagnosis. There was a significant impact of higher Karnofsky performance score (KPS) (≥80) on overall survival, p-log-rank test = 0.0002, whereas other parameters did not show any significant differences. The molecular analysis revealed TP53 mutations in 3/34 (8.82 %) cases; R273H, R306X, and Q136X. However, none of the analyzed samples contained the R132-IDH1 or R172-IDH2 mutations. These results showed the absence of IDH1 mutation in primary glioblastoma, confirming that this mutation is a hallmark of secondary glioblastoma. It can be used to distinguish primary from secondary glioblastomas. We found also that higher KPS was a significantly favorable factor in patients with primary glioblastoma.

Frequent MGMT (0(6)-methylguanine-DNA methyltransferase) hypermethylation in long-term survivors of glioblastoma: a single institution experience. Radiol Oncol 2010; 44:113-20.

Abstract
BACKGROUND The aim of this retrospective study was to analyse the MGMT (0(6)-methylguanine-DNA methyltransferase) promoter methylation status in long-term surviving (≥ 3 years) patients with glioblastoma multiforme (GBM). METHODS The methylation status of the MGMT promoter was determined by bisulfite modification of the DNA and subsequent methylation-specific polymerase-chain-reaction (MSP). DNA was extracted from routinely formalin-fixed and paraffin-embedded tumour tissue samples. RESULTS MSP yielded interpretable results in only 14 of 33 (42%) long-term surviving patients with GBM. A methylated band was seen in 3 of 14, methylated as well as unmethylated bands in 8 of 14 and an only unmethylated band in 3 of 14 patients, thus, yielding MGMT promoter methylation in 11 of 14 patients. The two groups of patients with methylated and unmethylated MGMT promoter status were too small to draw any firm statistical conclusions. CONCLUSIONS Long-term surviving patients with GBM have very frequently intratumoural MGMT promoter methylation. This phenomenon discriminates long-term survivors from a non-selected group of patients with GBM. The standardization of the MSP for the determination of the MGMT promoter methylation status seems to be necessary in order to make this methodology a more reliable one.

Abstract
BACKGROUND Glioblastoma is a highly lethal neoplasm with a median survival of 12-14 months; only 2-5% of patients survive >3 years. METHODS At our institute, patients with glioblastoma are initially treated with maximum tumor resection followed by radiation and the intravenous injection of nimustine hydrochloride (ACNU). RESULTS Using this strategy, 18 of 123 (14.6%) patients treated at our hospital survived >3 years; 7 manifested no recurrence, and the other 11 had early recurrence and received additional therapies. To identify factors associated with prolonged survival, we compared these patients with 21 short-term (<1.5 years) glioblastoma survivors. In the long-term survivors, the MGMT promoter methylation was significantly more frequent. The rate of p53 mutation was lower, and the rate of PTEN mutations and the proliferation index were slightly higher in short-term survivors. CONCLUSION By multivariate analysis, we found that a younger age and MGMT promoter methylation were significant favorable factors in patients with glioblastoma.

Abstract
Advances in the fields of molecular and translational research, oncology, and surgery have emboldened the medical community to believe that intrinsic brain tumors may be treatable. Intraoperative imaging and brain mapping allow operations adjacent to eloquent cortex and more radical resection of tumors with increased confidence and safety. Despite these advances, the infiltrating edge of a neoplasm and distant microscopic satellite lesions will never be amendable to a surgical cure. Indeed, it is continued research into the delivery of an efficacious chemobiologic agent that will eventually allows us to manage this primary cause of treatment failure.

Abstract
Most adult glioblastoma multiformes (GBMs) present in patients 45-70 years old; tumors occurring at the extremes of the adult age spectrum are uncommon, and seldom studied. We hypothesized that young-adult GBMs would differ from elderly-adult and from pediatric GBMs. Cases were identified from years 1997 to 2005. Demographic and histological features, MIB-1 and TP53 immunohistochemical findings and epidermal growth factor receptor (EGFR) amplification status by fluorescence in situ hybridization were compiled and correlated with survival. Twenty-eight (74%) of our 38 young-adult GBM patients had primary de novo tumors, two of which occurred in patients with cancer syndromes. Two additional GBMs were radiation-induced and eight (21%) were secondary GBMs. Seven patients were identified as long-term (>3 years) survivors. Six of 38 cases manifested unusual morphological features, including three epithelioid GBMs, one rhabdoid GBM, one gliosarcoma and one small cell GBM containing abundant, refractile, eosinophilic inclusions. MIB-1 index emerged as the most important prognosticator of survival (P < 0.005). Although there was a trend between extent of necrosis, TP53 immunohistochemical expression, and EGFR amplification status and survival, none reached statistical significance. GBMs in young adults are a more inhomogeneous tumor group than GBMs occurring in older adult patients and show features that overlap with both pediatric and adult GBMs.

Abstract
Object. The goal of this study was to investigate survival and functional outcomes in patients with high-grade intracranial astrocytomas as a function of the location of the lesion in the dominant or nondominant hemisphere (DH and NDH, respectively), and to suggest management strategies for such patients based on these data.
Methods. Data were collected from the Glioma Outcomes Project database, a longitudinal database of demographic, clinical, and outcome data for patients with high-grade intracranial gliomas. From the entire database of 788 patients, a subset of all 280 right-handed patients with newly diagnosed, unilateral gliomas involving potentially eloquent cortex was selected as the sample population. Two cohorts were defined based on the location of the tumor in the right or left cerebral hemisphere. All other relevant demographic and clinical data were nearly identical between the cohorts. A Kaplan—Meier analysis was conducted to assess survival, and Karnofsky Performance Scale scores assigned at 6 and 12 months postoperatively were compared as a measure of functional outcome.
The analysis demonstrated no difference in survival between patients with lesions in the DH and those with tumors in the NDH. Additionally, no statistically significant difference in functional outcomes was observed between the two groups.
Conclusions. Laterality of high-grade gliomas is not an independent prognostic factor for predicting survival or functional outcome. The findings in this study demonstrate that fears of increased postoperative morbidity or mortality in otherwise resectable tumors of the DH are unfounded, and the authors therefore advocate that the surgeon's decision to operate be guided by validated outcome predictors and not biased by tumor lateralization.

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
OBJECT The goal of this study was to determine whether the presence of a large tumor cyst was associated with improved outcome in patients undergoing surgery for newly diagnosed glioblastomas multiforme (GBMs) by comparing these patients with a matched cohort of patients with noncystic GBMs in clinical features, tumor imaging characteristics, survival, and time to tumor recurrence after surgery. METHODS A retrospective analysis was conducted in 22 patients by using imaging information and chart reviews of operative reports of GBMs with large cysts (> or = 50% of tumor volume) at The University of Texas M. D. Anderson Cancer Center between 1993 and 2002. Clinical and neurosurgical outcomes and recurrence rates were studied. A statistical comparison was made with a matching cohort of 22 patients with noncystic GBMs. No significant differences in clinical variables were found between the cohort with cystic GBMs and the matched cohort with noncystic GBMs. To avoid bias in preoperative assessment of tumor volume, the tumor burden was compared in patients whose tumors had cysts (excluding the cystic mass) and in patients whose tumors did not contain cysts. There was no statistically significant difference between the two groups (p = 0.8). In patients with cystic GBMs the median survival time after surgery was 18.2 months (95% confidence interval [CI] 11.9-24.5 months) and at 2 years 43% of the patients were still alive. In comparison, in patients with noncystic GBMs, the median survival time was 14.3 months (95% CI 12.1-16.4 months) and only 16% of patients were alive at 2 years. The median time to tumor recurrence was 7.6 months (95% CI 0.01-18 months) in patients harboring cystic GBMs and 4.2 months (95% CI 1.8-6.6 months) in the matched cohort (log-rank test, p = 0.04). In the cystic GBM group, no recurrence was observed in 53% of patients at 6 months, 45% at 1 year, and 38% at 2 years after surgery, whereas the corresponding numbers for the noncystic group were 36, 14, and 9%, respectively. CONCLUSIONS The results indicate that patients harboring a GBM that contains a large cyst survive longer and have a longer time to recurrence than those who lack such a cyst. This is the first such observation in the literature.

Abstract
Unlike most patients with glioblastoma multiforme who survive less than a year, approximately 2% have an unusually long survival after diagnosis and contemporary treatment (> or = 3 or more years); rarely, the disease appears to be "cured." Understanding these rare patients may tell us something important about the biology of glioblastoma multiforme. Patients who are young, have good performance status, and receive multimodalitytherapy (i.e., surgical resection, radiotherapy, and adjuvant chemotherapy) are more likely to have a long survival than older patients with poor performance status who are treated identically. However, the aforementioned clinical characteristics of long-term survivors do not explain why most patients with glioblastoma multiforme who have this same constellation of favorable features succumb to the disease relatively quickly. "Glioblastoma multiforme" is a group of diseases, one subtype of which behaves in a more indolent fashion, or responds well to current therapies, or both. In this review, we summarize the molecular characteristics of glioblastoma multiforme and pay special attention to molecular predictors of survival outcome, an area of research that is still in its infancy. We conclude by suggesting a translational research strategy that is aimed at uncovering the molecular signatures of long survivorship.

Abstract
Glioblastoma is the commonest neuroectodermal tumor and the most malignant in the range of cerebral astrocytic gliomas. The prognostic utility of various biological markers for glioblastomas has been broadly tested but the results obtained are regarded as controversial. In the present study, 302 glioblastoma specimens were studied to evaluate a possible association between clinical outcome and expression of some immunohistochemical variables. Furthermore, tumors examined were subdivided on the three cytological subsets--small-cell (SGB), pleomorphic-cell (PGB) and gemistocytic (GGB). Immunohistochemical variables differed between various subsets: the number of p53-positive tumors was found to be prevailed among the PGB, whereas the number of tumors with EGFR and mdm2 positivity was significantly greater in SGB. GGB contained significantly lowest mean proliferating cell nuclear antigen (PCNA) labeling index (LI), greater number of p21ras positive cases, and higher mean apoptotic index (AI). Survival time in patients with SGB, EGFR and mdm2-positivity and PCNA LI >40% was found to be significantly shorter, whereas presence of p21ras and AI >0.5% were associated with prolonged survival. Multivariate analysis revealed that survival time is associated with SGB, EGFR-positivity, and AI (p = 0.0023, p = 0.0035 and p = 0.0029 respectively). We conclude that although some immunohistochemical variables were found to be significant for glioblastoma outcome, they appear to be closely related to biology of single cytological subsets. Furthermore, these variables exhibited no prognostic value when they were analyzed within each cytological subset separately. Therefore, the glioblastoma subdivision on three cytological subsets proposed by us is carrying some element of rationality but, undoubtedly, requires further prospective studies.

Abstract
OBJECT One of the most frequent genetic abnormalities found in patients with glioblastoma multiforme (GBM) is homozygous deletion of the p16 tumor suppressor gene. The authors investigated whether this deletion is associated with prognosis in patients with GBM. METHODS In 46 adult patients with supratentorial GBM, homozygous deletion of the p16 gene in tumor DNA was examined using the multiplex polymerase chain reaction assay. The deletion was confirmed in 14 (30.4%) of 46 patients, eight (30.8%) of 26 men and six (30.0%) of 20 women. Cox proportional hazard regression analysis, adjusted for age at surgery, the Karnofsky Performance Scale score, extent of resection, and the MIB-1 labeling index. revealed that homozygous deletion of the p16 gene was significantly associated with overall survival and progression-free survival in men, but not in women. CONCLUSIONS The results of this study suggest that p16 homozygous deletion is a significant unfavorable prognostic factor in male patients with GBM.

Abstract
PURPOSE To evaluate the impact of tumor volume on survival of patients reirradiated with (192)Ir for recurrent glioblastoma. METHODS AND MATERIALS Between 1993 and 1997, 42 patients with recurrent glioblastomas (29 males and 13 females, age 18-69 years, median age 49) were treated with (192)Ir implantation. Previous treatments included surgery, external beam radiotherapy, and chemotherapy. Maximum diameter of the recurrent tumor was 1.2-10.1 cm (median: 5.7 cm) and tumor volume was 1.6-122 cm(3) (median: 23 cm(3)). Karnofsky performance status score was 50-100 (median: 80). Brachytherapy dose was 40-60 Gy. RESULTS Probability of overall survival was 80% at 6 months, 48% at 1 year, and 11% at 2 years. Median survival was 50 weeks. Univariate analysis showed that both tumor volume (T < or T > or = 30 cm(3)) and Karnofsky performance status score were significant predictors of survival. Multivariate analysis showed that smaller tumor volumes were associated with a higher probability of survival (p < 0.001). CONCLUSION Tumor volume less than 30 cm(3) was associated with a higher probability of, and quality of, survival than larger lesions for patients reirradiated by brachytherapy for recurrent glioblastoma.

Abstract
Glioblastoma multiforme (WHO grade IV; GBM) is the most common primary brain tumor with a median survival of less than one year despite multimodal treatment regimens. However, a small subgroup of GBM patients has a better clinical outcome, with a small number of patients surviving several years. Apoptosis, a genetically determined program of cell suicide, may be induced as a consequence of critical DNA damage. However, due to defects in the signaling pathways, cancer cells may escape apoptosis, despite carrying irreversible DNA damage. In the present study, we have analyzed tumors of two age-matched, equally treated groups of GBM patients with different postoperative time to tumor progression (TTP), defined as 'short-term' for TTP of less than 6 months (n = 54), and 'long-term' for TTP of more than 12 months (n = 39) for alterations in apoptosis regulatory pathways: Mutations of the TP53 tumor suppressor gene and/or nuclear accumulation of its gene product p53, expression of Waf/p21, CD95 (Apo1/Fas), and Bcl-2. TP53 mutations were found in 12 out of 54 (22%) GBMs of short-term survivors and 8 out of 35 (23%) tumors of long-term survivors; the respective numbers for nuclear p53 protein accumulation were 12/53 (23%) and 10/37 (27%). Waf1/p21 expression was found in 13/53 (25%) tumors of short-term survivors and 9/35 (26%) GBMs of long-term survivors. The respective numbers for Bcl-2 expression were 25/42 (60%) and 22/36 (61%) and for CD95 (Apo1/Fas) expression 20/49 (41%) and 14/36 (39%) GBMs. The percentage of alterations in genes/proteins involved in the apoptotic pathway investigated here was virtually identical in the two groups of clinically different GBM patients. Thus, our data imply that none of these alterations investigated per se has a strong impact on the overall survival of GBM patients.

Abstract
The authors report on a patient who had undergone resection of a left-sided temporal giant cell glioblastoma at the age of 69 years and who survived for more than 17 years. This man had not undergone postoperative radiotherapy or adjuvant chemotherapy. He died at the age of 86 years without clinical evidence of tumor recurrence. Histologically, the lesion was characterized by highly pleomorphic tumor cells (including bizarre multinucleated giant cells) with high mitotic activity, large necroses, and prominent mononuclear infiltration. A point mutation in the TP53 tumor suppressor gene (c.524G>A; R175H) and no epidermal growth factor receptor gene amplification were revealed on molecular genetic analysis. No diagnostic chromosomal imbalances were identified on comparative genomic hybridization, although the average ratio profile for chromosome 10 indicated loss of 10p15 in a subpopulation of tumor cells. This patient is exceptional because tumor resection, probably in conjunction with a marked antitumor immune response, apparently resulted in eradication of the lesion.

Abstract
Despite multimodal therapy, glioblastoma multiforme (GBM) is associated with a poor prognosis with a median survival of less than 1 year. However, a small number of patients with GBM shows survival times of several years. Although clinical features like age and performance status at diagnosis are well known prognostic parameters, molecular markers for prognosis of overall survival are still lacking. Therefore, we compared 2 age- and gender-matched groups of GBM patients with different post-operative time to tumor progression (TTP), defined as 'short-term' for TTP of less than 6 months (n = 21), and 'long-term' for TTP of more than 24 months (n = 21) for genetic alterations of the PTEN, CDKN2A and TP53 genes as well as overexpression of the EGFR, p53 and Mdm2 proteins. For the GBMs with 'short-term' TTP vs. 'long-term' TTP, the studies revealed PTEN mutations in 4/21 vs. 2/21, TP53 mutations in 5/21 vs. 8/21, homozygous deletion of the CDKN2A gene in 5/21 vs. 6/21, overexpression of EGFR in 7/20 vs. 10/20, accumulation of p53 protein in 9/20 vs. 7/20 and of Mdm2 protein in 0/20 vs. 1/20 cases studied. Taken together, our data indicate that mutations of the PTEN and TP53 tumor suppressor genes, homozygous deletion of the CDKN2A gene as well as overexpression of the EGFR, p53 and Mdm2 proteins lack prognostic significance for overall survival time in patients with GBMs.

Abstract
We report two cases of "decade survivor" of glioblastoma. Case 1 is a 34-year-old female who developed a tumor in the left frontal pole, and Case 2 is a 46-year-old male with a left frontal tumor. Both tumors were surgically excised and the patients received postoperative chemo-radiotherapy. Histological re-evaluation of the resected tumor tissue confirmed the most malignant type of glioma-glioblastoma. We speculate that the entire extent of tumors had been extirpated by surgery in both cases.

Abstract
Glioblastoma, a malignant tumor of neuroepithelial origin, is relatively uncommon in childhood, during which it accounts for 7%-9% of brain tumors. A few patients (about 3%) live more than 5 years. We report a 13-year-old girl who was admitted because one month earlier she had begun to present headache and diplopia. Brain computed tomography (CT) showed a right frontal tumor. At operation, complete excision of the visible tumor was performed. Histologic examination showed that the tumor was a glioblastoma multiforme. The patient underwent 52 Gy of external beam radiotherapy to the enhancing tumor mass plus 3-cm border, and chemotherapy with nitrosourea (BCNU). Fourteen years, 9 months later, the patient presents neither neurological deficits nor radiological relapse. We confirm that younger age, the one immutable prognostic factor, supports a particularly aggressive approach to the treatment of glioblastomas.

Abstract
BACKGROUND Long-term glioblastoma multiforme survivors (LTGBMS) are uncommon. The frequency which these occur in an unselected population and factors which produce these unusually long survivors are unknown. OBJECTIVES To determine in a population-based study 1) the frequency of LTGBMS in a population and 2) identify which patient, treatment or tumor characteristics would predict which glioblastoma (GBM) patient would become a LTGBMS. METHODS The Alberta Cancer Registry was used to identify all patients diagnosed with GBM in southern Alberta between 1/1/75-12/31/91. Patient charts were reviewed and histology re-examined by a blinded neuropathologist. LTGBMS were defined as GBM patients surviving > or = 3 years after diagnosis. Each LTGBMS was compared to three age-, gender-, and year of diagnosis-matched controls to compare patient, treatment, and tumor factors to GBM patients without long-term survival. RESULTS There were 279 GBMs diagnosed in the study period. Five (1.8%) survived > or = three years (range, 3.2-15.8 years). Seven additional long-term survivors, who carried a diagnosis of GBM, were excluded after neuropathologic review; the most common revised diagnosis was malignant oligodendroglioma. LTGBMS (avg. age = 45 years) were significantly younger when compared to all GBM patients (avg. age = 59 years, p = 0.0001) diagnosed in the study period. LTGBMS had a higher KPS at diagnosis (p = 0.001) compared to controls. Tumors from LTGBMS tended to have fewer mitoses and a lower Ki-67 cellular proliferative index compared to controls. Radiation-induced dementia was common and disabling in LTGBMS. CONCLUSIONS These data highlight the dismal prognosis for GBM patients who have both a short median survival and very small chance (1.8%) of long-term survival. The LTGBMS were younger, had a higher performance status, and their tumors tended to proliferate less rapidly than control GBM patients. When long-term survival does occur it is often accompanied by severe treatment-induced dementia.

Abstract
Anaplastic mixed gliomas are rare tumors that occur mostly in the cerebral hemispheres. They have a distinctive histological appearance characterized by the presence of two or more glial cellular constituents. The incidence of malignant mixed glioma of the brainstem and posterior fossa is extremely low. The authors report an unusual case of an exophytic malignant mixed glioma. Following subtotal resection, the patient received conventional radiotherapy, but continued to deteriorate, and died five months after surgery. The extensive literature review focuses on histopathology, clinical features, natural history, and possible treatment modalities of this unusual neoplasm.

Abstract
A 26-year-old man with anaplastic glioma in the left frontoparietal lobe survived for 9 years and 9 months after combined therapy, including subtotal resection, postoperative irradiation, and chemotherapy. The tumor recurred and he received immunotherapy using lymphokine-activated killer (LAK) cells. At the last LAK cell infusion, infection of the Ommaya reservoir occurred, but subsided after antibiotics were administered. Follow-up neuroimaging showed no recurrence of the tumor. Review of the surgical specimens found that the original diagnosis of glioblastoma was inconclusive, although the tumor is considered to be a type of anaplastic glioma.

Abstract
The authors report 11 patients with cerebral glioblastoma who lived at least 5 years after their initial diagnosis. There were 6 female and 5 male; the mean age was 39 years (range 24-55 years). All patients were treated surgically and postoperatively received whole-brain radiotherapy and chemotherapy. Five patients (45%) presented local recurrences after an average interval of 3.9 years from treatment. At average follow-up of 9 years (range 5-14 years), 7 patients (64%) were alive after an average interval of 8.1 years; 4 patients (36%) died from local relapse. Survival was influenced by patient age and, to a lesser degree, by treatment. A review of the literature, together with our own series, suggest that death from recurrence disease is unusual in glioblastoma patients who survive more than 5 years.

Abstract
Seventy-one histologically malignant brain tumors, 52 histologically benign brain tumors, and 14 cerebral metastases were characterized according to DNA content and proliferative capacity. DNA ploidy, DNA index (DI), S-phase fraction (SPF), 5-bromo-2'-deoxy-uridine (BrdUrd) labelling index (LI), duration of S-phase (Ts), and potential doubling time (Tpot) were assessed by flow cytometry (FCM). In histologically benign tumors, a high percentage of DNA diploid tumors and a low proliferative capacity in DNA diploid tumors were found. Histologically malignant tumors and cerebral metastases were both found to be characterized by a low percentage of DNA diploid tumors and a high proliferative capacity in DNA diploid tumors. The proliferative capacity of DNA aneuploid benign tumors and that of DNA aneuploid malignant tumors, however, appeared not to differ significantly. The number of DNA aneuploid tumors was small. Duration of S-phase was short (range 3.9-4.7 hr) and appeared not to differ between the three groups. From this, the observed differences in Tpot values should be accredited mainly to differences in LI. High-grade as well as low-grade gliomas both appeared to be characterized by malignant (FCM) features, i.e., 1) a high percentage DNA aneuploidy, 2) a high mean DI (for DI > 1), and 3) a high proliferative capacity.

Abstract
Long term survival is rare in patients with glioblastoma multiforme (GBM). To determine if the tumors of patients with long survivals constitute a subgroup of patients with identifiable molecular genetic characteristics, we studied the p53 gene and Epidermal Growth Factor Receptor (EGF-R) expression in long-term survivors of GBM. A review of the Tumor Registry of Memorial Hospital for Cancer and Allied Diseases documented that 521 patients were treated for GBM between 1954 and 1987 and that 12 patients had seven-year or longer survivals. Six additional long-term survivors were identified from other institutions. After pathological re-examination, the diagnosis of 8 of these 18 (44%) tumors was changed to other histologic tumor types. Using immunohistochemical analysis, 4 of 10 confirmed malignant gliomas had over-expression of p53. Polymerase chain reaction/single-strand conformational polymorphism (PCR/SSCP) analysis and sequence analysis of these 4 tumors showed no p53 mutations in exons 5-8, the region where most mutations have been reported in human malignancies. Immunohistochemical analysis for EGF-R was performed on the tumors of the 10 long-term survivors. EGF-R over-expression was identified in 4 (40%), which is consistent with previous reported studies for GBM in general. These findings suggest that there is a subset of GBM defined by the accumulation of wild-type p53 and that the over-expression of EGF-R does not preclude long-term survival. The seven-year survival rate for confirmed GBM in patients from the Memorial Hospital Tumor Registry was at least 1%.

Abstract
A retrospective review was undertaken to study the influence of age on the survival of patients undergoing brachytherapy boost for glioblastoma multiforme. From February 1981 through December 1992, 159 adults with primary glioblastoma multiforme underwent high-activity iodine-125 brain implant boost after external beam radiotherapy. There were 98 men and 61 women, ranging in age from 18 to 73 years (median, 52 yr). Karnofsky performance scores ranged from 70 to 100 (median, 90). Surgery before radiotherapy consisted of biopsy in 7% of patients, subtotal resection in 66%, and gross total resection in 27%. External beam radiotherapy doses ranged from 39.6 to 76.8 Gy, with 91% of patients receiving 59.4 to 61.2 Gy. Brachytherapy doses ranged from 35.7 to 66.5 Gy (median, 55.0 Gy) at 0.30 to 0.70 Gy per hour (median, 0.43 Gy/h). Reoperations were performed in 81 patients (51%). Information on quality of life was available for 13 of the 14 living 3-year survivors; 10 patients were steroid independent, and mean Karnofsky performance scores had decreased from 92 at the time of brachytherapy to 75 at the last follow-up. Univariate and multivariate analyses showed that age was the most important parameter influencing survival (P < 0.0005). The nine patients 18 to 29.9 years old had a 3-year survival probability of 78 +/- 14% (median survival was not yet reached at the time of this report), with a follow-up of 145 to 511 weeks in living patients (median, 322 wk).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Histological grading of fibrillary astrocytic neoplasms has proved to be a valuable prognostic tool, but potentially could benefit from more objective data, such as estimates of proliferative rate. The authors have investigated the prognostic utility of quantitative Ki-67 immunoreactivity in a prospective survival analysis of 36 adult patients with astrocytoma, anaplastic astrocytoma, or glioblastoma multiforme diagnosed between 1987 and 1992. A digital image analyzer was used to assay proliferation indices (PIs) in surgical biopsy specimens obtained at first diagnosis (32 of 36) or at a second biopsy of histologically unchanged high-grade disease (4 of 36). A Ki-67 PI of > or = 7.5% was associated with higher histological grade and poorer survival, and the Ki-67 PI was more significantly related to survival (P < 0.001) than histological grade as determined by a modified Ringertz grading system (P = 0.002). Survival analysis within histological grades suggested that astrocytoma patients with PI > or = 3% may be at increased risk for shorter survival than those with PI < 3%.
