OBJECT The prognosis of elderly patients with glioblastoma (GBM) is universally poor. Currently, few studies have examined postoperative outcomes and the effects of various modern therapies such as bevacizumab on survival in this patient population. In this study, the authors evaluated the effects of various factors on overall survival in a cohort of elderly patients with newly diagnosed GBM. METHODS A retrospective review was performed of elderly patients (≥ 65 years old) with newly diagnosed GBM treated between 2004 and 2010. Various characteristics were evaluated in univariate and multivariate stepwise models to examine their effects on complication risk and overall survival. RESULTS A total of 120 patients were included in the study. The median age was 71 years, and sex was distributed evenly. Patients had a median Karnofsky Performance Scale (KPS) score of 80 and a median of 2 neurological symptoms on presentation. The majority (53.3%) of the patients did not have any comorbidities. Tumors most frequently (43.3%) involved the temporal lobe, followed by the parietal (35.8%), frontal (32.5%), and occipital (15.8%) regions. The majority (57.5%) of the tumors involved eloquent structures. The median tumor size was 4.3 cm. Every patient underwent resection, and 63.3% underwent gross-total resection (GTR). The vast majority (97.3%) of the patients received the postoperative standard of care consisting of radiotherapy with concurrent temozolomide. The majority (59.3%) of patients received additional agents, most commonly consisting of bevacizumab (38.9%). The median survival for all patients was 12.0 months; 26.7% of patients experienced long-term (≥ 2-year) survival. The extent of resection was seen to significantly affect overall survival; patients who underwent GTR had a median survival of 14.1 months, whereas those who underwent subtotal resection had a survival of 9.6 months (p = 0.038). Examination of chemotherapeutic effects revealed that the use of bevacizumab compared with no bevacizumab (20.1 vs 7.9 months, respectively; p < 0.0001) and irinotecan compared with no irinotecan (18.0 vs 9.7 months, respectively; p = 0.027) significantly improved survival. Multivariate stepwise analysis revealed that older age (hazard ratio [HR] 1.06 [95% CI1.02–1.10]; p = 0.0077), a higher KPS score (HR 0.97 [95% CI 0.95–0.99]; p = 0.0082), and the use of bevacizumab (HR 0.51 [95% CI 0.31–0.83]; p = 0.0067) to be significantly associated with survival. CONCLUSION This study has demonstrated that GTR confers a modest survival benefit on elderly patients with GBM, suggesting that safe maximal resection is warranted. In addition, bevacizumab significantly increased the overall survival of these elderly patients with GBM; older age and preoperative KPS score also were significant prognostic factors. Although elderly patients with GBM have a poor prognosis, they may experience enhanced survival after the administration of the standard of care and the use of additional chemotherapeutics such as bevacizumab.

TPS2105 Background: The standard of care for patients with newly diagnosed glioblastomas after surgical resection is radiotherapy with concomitant and adjuvant temozolomide chemotherapy. Yet, inclusion into the pivotal trial was limited to patients up to the age of 70, and subgroup analyses suggested that older patients did not gain benefit from combined modality treatment. Further, the efficacy of radiotherapy has been confirmed in a randomized trial comparing best supportive care versus radiotherapy alone. Of note, hypofractionated radiotherapy is equieffective in patients aged 65-70 years and more. Two randomized trials in elderly patients (NOA-08, Nordic Trial) indicated smilar efficacy of primary temozolomide chemotherapy alone compared with radiotherapy alone. Combined radiochemotherapy is compared with radiotherapy alone in an ongoing NCIC-CTG EORTC TROG Japanese group trial 26062-22061. Thus, radiotherapy alone is the standard of care for newly diagnosed glioblastoma of elderly patients. These clinical data justify the exploration of new, temozolomide-free first-line treatment strategies in elderly patients. Methods: The ARTE trial will therefore investigate bevacizumab when added to a short course of radiotherapy and bevacizumab maintenance therapy until progression. The translational research program shall include blood and urine biomarker analysis and FET-PET in addition to MRI for monitoring the course of the disease. This trial is an explorative randomized, non-comparative phase II trial aiming at recruiting 60 patients in Switzerland. Elderly patients (> 65) will be randomized 2:1 either to the experimental arm (bevacizumab plus radiotherapy) or the standard arm (radiotherapy). The primary endpoint is median overall survival. Secondary endpoints include overall survival at 6 months, overall survival at 12 months, median progression-free survival, progression-free survival at 6 months, median time to treatment failure.

Object Extent of resection (EOR) has been shown to be an important prognostic factor for survival in patients undergoing initial resection of glioblastoma (GBM), but the significance of EOR at repeat craniotomy for recurrence remains unclear. In this study the authors investigate the impact of EOR at initial and repeat resection of GBM on overall survival. Methods Medical records were reviewed for all patients undergoing craniotomy for GBM at the University of California San Francisco Medical Center from January 1, 2005, through August 15, 2009. Patients who had a second craniotomy for pathologically confirmed recurrence following radiation and chemotherapy were evaluated. Volumetric EOR was measured and classified as gross-total resection (GTR, > 95% by volume) or subtotal resection (STR, ≤ 95% by volume) after independent radiological review. Overall survival was compared between groups using univariate and multivariate analysis accounting for known prognostic factors, including age, eloquent location, Karnofsky Performance Status (KPS), and adjuvant therapies. Results Multiple resections were performed in 107 patients. Fifty-two patients had initial GTR, of whom 31 (60%) had GTR at recurrence, with a median survival of 20.4 months (standard error [SE] 1.0 months), and 21 (40%) had STR at recurrence, with a median survival of 18.4 months (SE 0.5 months) (difference not statistically significant). Initial STR was performed in 55 patients, of whom 26 (47%) had GTR at recurrence, with a median survival of 19.0 months (SE 1.2 months), and 29 (53%) had STR, with a median survival of 15.9 months (SE 1.2 months) (p = 0.004). A Cox proportional hazards model was constructed demonstrating that age (HR 1.03, p = 0.004), KPS score at recurrence (HR 2.4, p = 0.02), and EOR at repeat resection (HR 0.62, p = 0.02) were independent predictors of survival. Extent of initial resection was not a statistically significant factor (p = 0.13) when repeat EOR was included in the model, suggesting that GTR at second craniotomy could overcome the effect of an initial STR. Conclusions Extent of resection at recurrence is an important predictor of overall survival. If GTR is achieved at recurrence, overall survival is maximized regardless of initial EOR, suggesting that patients with initial STR may benefit from surgery with a GTR at recurrence.

Object The value of extent of resection (EOR) in improving survival in patients with glioblastoma multiforme (GBM) remains controversial. Specifically, it is unclear what proportion of contrast-enhancing tumor must be resected for a survival advantage and how much survival improves beyond this threshold. The authors attempt to define these values for the patient with newly diagnosed GBM in the modern neurosurgical era. Methods The authors identified 500 consecutive newly diagnosed patients with supratentorial GBM treated at the University of California, San Francisco between 1997 and 2009. Clinical, radiographic, and outcome parameters were measured for each case, including MR imaging–based volumetric tumor analysis. Results The patients had a median age of 60 years and presented with a median Karnofsky Performance Scale (KPS) score of 80. The mean clinical follow-up period was 15.3 months, and no patient was unaccounted for. All patients underwent resection followed by chemotherapy and radiation therapy. The median postoperative tumor volume was 2.3 cm3, equating to a 96% EOR. The median overall survival was 12.2 months. Using Cox proportional hazards analysis, age, KPS score, and EOR were predictive of survival (p < 0.0001). A significant survival advantage was seen with as little as 78% EOR, and stepwise improvement in survival was evident even in the 95%–100% EOR range. A recursive partitioning analysis validated these findings and provided additional risk stratification parameters related to age, EOR, and tumor burden. Conclusions For patients with newly diagnosed GBMs, aggressive EOR equates to improvement in overall survival, even at the highest levels of resection. Interestingly, subtotal resections as low as 78% also correspond to a survival benefit.

Abstract BACKGROUND Glioblastoma (GBM) is the most common malignant brain tumor in adult patients. Tumor recurrence commonly occurs around the resection cavity, especially after subtotal resection (STR). Consequently, the extent of resection correlates with overall survival (OS), suggesting that depletion of postoperative tumor remnants will improve outcome. OBJECTIVE To assess safety and efficacy of adding stereotactic radiosurgery (SRS) to the standard treatment of GBM in patients with postoperative residual tumor. METHODS Gamma-GBM is a single center, open-label, prospective, single arm, phase II study that includes patients with newly diagnosed GBM (intraoperative via frozen sections) who underwent STR (residual tumor will be identified by native and contrast enhanced T1-weighted magnetic resonance imaging scans). All patients will receive SRS with 15 Gy (prescribed to the 50% isodose enclosing all areas of residual tumor) early (within 24-72 h) after surgery. Thereafter, all patients undergo standard-of-care therapy for GBM (radiochemotherapy with 60 Gy external beam radiotherapy [EBRT] plus concomitant temozolomide and 6 cycles of adjuvant temozolomide chemotherapy). The primary outcome is median progression-free survival, secondary outcomes are median OS, occurrence of radiation induced acute (<3 wk), early delayed (<3 mo), and late (>3 mo post-SRS) neurotoxicity and incidence of symptomatic radionecrosis. EXPECTED OUTCOMES We expect to detect efficacy and safety signals by the immediate application of SRS to standard-of-care therapy in newly diagnosed GBM. DISCUSSION Early postoperative SRS to areas of residual tumor could bridge the therapeutic gap between surgery and adjuvant therapies.

Object The prognosis of patients with glioblastoma who present with multifocal disease is not well documented. The objective of this study was to determine whether multifocal disease on initial presentation is associated with worse survival. Methods The authors retrospectively reviewed records of 368 patients with newly diagnosed glioblastoma and identified 47 patients with multifocal tumors. Each patient with a multifocal tumor was then matched with a patient with a solitary glioblastoma on the basis of age, Karnofsky Performance Scale (KPS) score, and extent of resection, using a propensity score matching methodology. Radiation and temozolomide treatments were also well matched between the 2 cohorts. Kaplan-Meier estimates and log-rank tests were used to compare patient survival. Results The incidence of multifocal tumors was 12.8% (47/368). The median age of patients with multifocal tumors was 61 years, 76.6% had KPS scores ≥ 70, and 87.2% underwent either a biopsy or partial resection of their tumors. The 47 patients with multifocal tumors were almost perfectly matched on the basis of age (p = 0.97), extent of resection (p = 1.0), and KPS score (p = 0.80) compared with 47 patients with a solitary glioblastoma. Age (>65 years), partial resection or biopsy, and low KPS score (<70) were associated with worse median survival within the multifocal group. In the multifocal group, 19 patients experienced tumor progression on postradiation therapy MRI, compared with 11 patients (26.8%) with tumor progression in the unifocal group (p = 0.08). Patients with multifocal tumors experienced a significantly shorter median overall survival of 6 months (95% CI 4–10 months), compared with the 11-month median survival (95% CI 10–19 months) of the matched solitary glioblastoma group (p = 0.02, log-rank test). Two-year survival rates were 4.3% for patients with multifocal tumors and 29.0% for the unifocal cohort. Patients with newly diagnosed multifocal tumors were found to have an almost 2-fold increase in the hazard of death compared with patients with solitary glioblastoma (hazard ratio 1.8, 95% CI 1.1–3.1; p = 0.02). Tumor samples were analyzed for expression of phosphorylated mitogen-activated protein kinase, phosphatase and tensin homolog, O6-methylguanine-DNA methyltransferase, laminin β1 and β2, as well as epidermal growth factor receptor amplification, and no significant differences in expression profile between the multifocal and solitary glioblastoma groups was found. Conclusions Patients with newly diagnosed multifocal glioblastoma on presentation experience significantly worse survival than patients with solitary glioblastoma. Patients with multifocal tumors continue to pose a therapeutic challenge in the temozolomide era and magnify the challenges faced while treating patients with malignant gliomas.

Object The objective of this study was to analyze whether age influences the outcome of patients with glioblastoma and whether elderly patients with glioblastoma can tolerate the same aggressive treatment as younger patients. Methods Data from 361 consecutive patients with newly diagnosed cerebral glioblastoma (2000–2006) who underwent regular follow-up evaluation from initial diagnosis until death were prospectively entered into a database. Patients underwent resection (complete, subtotal, or partial) or biopsy, depending on tumor size, location, and Karnofsky Performance Scale score. Following surgery, all patients underwent adjuvant treatment consisting of radiotherapy, chemotherapy, or combined treatment. Patients older than 65 years of age were defined as elderly (146 total). Results Two hundred thirty-four patients underwent tumor resection (complete 26%, subtotal 29%, and partial 45%). One hundred twenty-seven underwent biopsy. Mean patient age was 61 years, and overall survival was 11.6 ± 12.1 months. The overall survival of elderly patients (9.1 ± 11.6 months) was significantly lower than that of younger patients (14.9 ± 16.7 months; p = 0.0001). Stratifying between resection or biopsy, age was a negative prognostic factor in patients undergoing biopsy (4.0 ± 7.1 vs 7.9 ± 8.7 months; p = 0.007), but not in patients undergoing tumor resection (13.0 ± 8.5 vs 13.3 ± 14.5 months; p = 0.86). Survival of elderly patients undergoing complete tumor resection was 17.7 ± 8.1 months. Conclusions In this series of patients with glioblastoma, age was a prognostic factor in patients undergoing biopsy, but not in patients undergoing resection. Tumor location and patient clinical status may prohibit extensive resection, but resection should not be withheld from patients only on the basis of age. In elderly patients with glioblastoma, undergoing resection to the extent feasible, followed by adjuvant therapies, is warranted.

Abstract INTRODUCTION Glioblastoma has a poor prognosis, further complicated by postoperative seizures. We analyzed various factors associated with postoperative seizures in glioblastoma. METHODS Retrospective chart review of 932 patients who underwent craniotomy for glioblastoma (777=83.4% newly diagnosed; 155=16.6% recurrent) at our institution (2002–2014). Postoperative seizures were defined as those occurring within 14 days of surgery. RESULTS Our cohort consisted of 49.9% (n=465) males with mean age of 55.8 (range 9–91) years. In total, 69 (7.4%) had postoperative seizures with mean time from surgery to seizure of 3.1 days (IQR=1–4). Of 536 patients (57.5%) receiving seizure prophylaxis, those treated with Keppra were more likely to have postoperative seizures compared to those on Dilantin (10.9% vs 5.0%; p=0.022). Primary tumor patients were less likely to seize postoperatively compared to recurrent tumor patients (9.7% vs 19%; p=0.016). Patients presenting with seizure as chief complaint (12.1% vs 5.1%; p=0.025) and those with >20% of Chromosome 10 deletion were more likely to have seizures postoperatively (12.4% vs 6.1%; p=0.0029). Risk factors for postop seizures for newly-diagnosed patients included subtotal resection versus gross total resection (28.0% vs 7.1%; p=0.022). Risk factors for postop seizures for recurrent patients were >5% EGFR amplification (23.5% vs 5.8%; p=0.0021) and hyponatremia within mean 2.5 days (IQR 0–1) after surgery (20.8% vs 7.1%; p=0.035). CONCLUSION We identified several risk factors for postoperative seizures in glioblastoma patients, most of which were clinical (seizure as chief complaint, the antiepileptic chosen for prophylaxis, and extent of resection), while some were molecular and linked to genes whose products have demonstrated links to epileptogeneicity (Chromosome 10, EGFR). These findings may assist physicians in detecting glioblastoma patients that are at higher risk for postoperative seizures and in providing prophylaxis to reduce morbidity.

Purpose Until recently, melphalan and prednisone were the standards of care in elderly patients with multiple myeloma. The addition of thalidomide to this combination demonstrated a survival benefit for patients age 65 to 75 years. This randomized, placebo-controlled, phase III trial investigated the efficacy of melphalan and prednisone plus thalidomide in patients older than 75 years with newly diagnosed myeloma. Patients and Methods Between April 2002 and December 2006, 232 previously untreated patients with myeloma, age 75 years or older, were enrolled and 229 were randomly assigned to treatment. All patients received melphalan (0.2 mg/kg/d) plus prednisone (2 mg/kg/d) for 12 courses (day 1 to 4) every 6 weeks. Patients were randomly assigned to receive 100 mg/d of oral thalidomide (n = 113) or placebo (n = 116), continuously for 72 weeks. The primary end point was overall survival. Results After a median follow-up of 47.5 months, overall survival was significantly longer in patients who received melphalan and prednisone plus thalidomide compared with those who received melphalan and prednisone plus placebo (median, 44.0 v 29.1 months; P = .028). Progression-free survival was significantly prolonged in the melphalan and prednisone plus thalidomide group (median, 24.1 v 18.5 months; P = .001). Two adverse events were significantly increased in the melphalan and prednisone plus thalidomide group: grade 2 to 4 peripheral neuropathy (20% v 5% in the melphalan and prednisone plus placebo group; P < .001) and grade 3 to 4 neutropenia (23% v 9%; P = .003). Conclusion This trial confirms the superiority of the combination melphalan and prednisone plus thalidomide over melphalan and prednisone alone for prolonging survival in very elderly patients with newly diagnosed myeloma. Toxicity was acceptable.

Abstract BACKGROUND: Meningeal hemangiopericytoma (M-HPC) is a rare entity. OBJECTIVE: To characterize our institutional experience in treating M-HPC. METHODS: We reviewed the medical records of patients with M-HPC evaluated at The University of Texas M.D. Anderson Cancer Center between 1979 and 2009. RESULTS: We identified 63 patients diagnosed between 1979 and 2009 with M-HPC treated with surgery alone or with postoperative radiotherapy (PORT). The majority were male (59%) and with a median age of 40.9 years (range, 0-71). Gross total resection (GTR) predominated (n = 31, 49%) followed by subtotal resection (n = 23, 37%) and unknown status (n = 9, 14.3%). PORT was delivered to 39 of the 63 patients (62%). The 5-, 10-, and 15-year overall survival were 90%, 68%, and 28%, respectively. The 5-, 10-, and 15-year local control (LC) were 70%, 37%, and 20%, respectively. The 5-, 10-, and 15-year metastasis-free survival were 85%, 39%, and 7%. PORT resulted in improved LC (hazard ratio [HR] 0.38, P = .008). Radiotherapy (RT) dose ≥60 Gy correlated with improved LC relative to &lt;60 Gy (HR 0.12, P = .045). GTR correlated with improved LC (HR 0.40, P = .03). On multivariate analysis, PORT (HR 0.33, P = .003), GTR (HR = 0.33, P = .008), and RT dose ≥60 Gy (HR 0.33, P = .003) correlated with improved LC. Among those with GTR, PORT resulted in improved LC (HR 0.18, P = .027). Extent of resection and PORT did not correlate with improved overall survival. CONCLUSION: In M-HPC, both PORT and GTR independently correlate with improved LC. PORT improves LC following GTR. We recommend RT dose ≥60 Gy to optimize LC.

Abstract Abstract 1811 The presence of chromosomal aberrations is a characteristic feature of multiple myeloma (MM). Recently, Avet-Loiseau et al reported that amp5q31.3 and del12p13.31, detected by high-density, single-nucleotide polymorphism arrays analysis correlate with prognosis in MM patients who were treated upfront with conventional chemotherapy (JCO 2009; 27:4585–90). The aim of our study was to evaluate the effect of these chromosomal abberations on survival of patients with newly diagnosed MM or with relapsed/refractory myeloma who were treated with novel agent-based regimens. We studied 172 MM patients who were treated in a single center in Athens (Greece) during a 4-year period (2007–2011); 76 were newly-diagnosed and were treated upfront with either bortezomib- or IMiD-based regimens and 96 had relapsed or refractory MM and were treated with the combination of lenalidomide and dexamethasone with or without bortezomib (RD vs. VRD) based on the presence of previous peripheral neuropathy (Dimopoulos et al, Leukemia 2010;24:1769–78). A combined methodological approach of G-banding karyotypic analysis and interphase fluorescence in situ hybridization (FISH) was performed in all patients. G-banding analysis was performed according to the European Cytogenetic Guidelines and Quality Assurance (ECA, 2006). The clonality criteria and the karyotypic description followed the recommendations of the International System for Human Cytogenetic Nomenclature (ISCN, 2009). FISH was performed according to the Recommendations for FISH in MM (European Myeloma Network) on uncultured BM, either on cytoplasmic immunoglobulin-enhanced cells (cIg-FISH) or on nuclei from purified CD138+ plasma cells. Commercially available DNA probes (Abott-VYSIS) were used for the detection of del17p, del13q, add1q21, t(4;14) and t(14;16). The probes RP11-96J7 and RP11-578N7 (labeled by Empire Genomics, NY, USA) were used to detect amp5q31 and del12p13. The frequency of the studied chromosomal abnormalities is depicted in the table. There was a strong correlation between the presence of amp5q31 with hyperdiploidy (p=0.012) but amp5q31 did not correlate with the presence of any other of the studied chromosomal aberrations. The presence of del12p13 was correlated with the presence of del13q (p=0.001), t(4;14) (p=0.009) and del17p (p=0.005). Add1q21 also correlated with del13q (p<0.001), t(4;14) (p<0.001) and del17p (p=0.007). In patients with relapsed/refractory MM, who received either RD or VRD, the median overall survival was 19 months. Patients with amp5q31 had a median survival of 18 months (95% CI: 13–23 months) vs. 21 months of the others (95% CI: 8–35 months; p=0.737), while patients with del12p13 had a median survival of 27 months (95% CI: 0–57 months) vs. 19 months of the others (95% CI: 10–27 months; p=0.767). Of the other studied cytogenetic abnormalities, the presence of del17p (11 vs. 26 months; p=0.001), amp1q21 (12 vs. 26 months; p=0.001) and del13q by FISH (11 vs. 26 months; p=0.025), but not of t(4;14) (p=0.521), were associated with inferior overall survival. In patients with newly-diagnosed MM, the median overall survival was 57 months. The median survival of patients with amp5q31 was 46 months vs. 57 months of all others (p=0.315) and for patients with del12p13 has not been reached vs. 57 months of all others (p=0.379). In conclusion, amp5q31 and del12p13 are recurrent chromosomal abnormalities in MM. Amp5q31 is not associated with the presence of other genetic features, except hyperdiploidy. αmp5q31 or 12p13 was not predictive of survival ιn our series. However, further studies are needed in patients with newly diagnosed MM who receive novel agents upfront to validate the prognostic importance of amp5q31 and del12p13.TableCytogenetic abnormalityPatients at diagnosis (n=76)Relpased/refractory patients (n=96)p-valueamp5q3112 (15.7%)20 (20.8%)0.271amp5q31 as sole anomaly5 (6.5%)7 (7.2%)0.674del12p138 (10.5%)16 (16.6%)0.171del13q28 (36.8%)28 (29.1%)0.279del17p13 (17.1%)15 (15.6%)0.765add1q2115 (19.7%)26 (27%)0.303t(14;16)1 (1.3%)1 (1%)0.832t(4;14)4 (5.2%)10 (10.4%)0.221Hyperdiploidy/hypodiploidy10 (13.1%)/6 (7.8%)11 (11.4%)/13 (13.5%)0.301 Disclosures: No relevant conflicts of interest to declare.
