Object Antiangiogenic agents have recently shown impressive radiological responses in high-grade glioma. However, it is not clear if the responses are related to vascular changes or due to antitumoral effects. The authors report the mature results of a clinical study of bevacizumab-based treatment of recurrent high-grade gliomas. Methods Sixty-one patients with recurrent high-grade gliomas received treatment with bevacizumab at 10 mg/ kg every 2 weeks for 4 doses in an 8-week cycle along with either irinotecan or carboplatin. The choice of concomitant chemotherapeutic agent was based on the number of recurrences and prior chemotherapy. Results At a median follow-up of 7.5 months (range 1–19 months), 50 (82%) of 61 patients relapsed and 42 patients (70%) died of the disease. The median number of administered bevacizumab cycles was 2 (range 1–7 cycles). The median progression-free survival (PFS) and overall survival (OS) were 5 (95% confidence interval [CI] 2.3–7.7) and 9 (95% CI 7.6–10.4) months, respectively, as calculated from the initiation of the bevacizumab-based therapy. Radiologically demonstrated responses following therapy were noted in 73.6% of cases. Neither the choice of chemotherapeutic agent nor the performance of a resection prior to therapy had an impact on patient survival. Although the predominant pattern of relapse was local, 15 patients (30%) had diffuse disease. Conclusions Antiangiogenic therapy using bevacizumab appears to improve survival in patients with recurrent high-grade glioma. A possible change in the invasiveness of the tumor following therapy is worrisome and must be closely monitored.

BACKGROUND: At present, the classification of central nervous system tumors relies on molecular factors in addition to histologic features to identify many tumor types. This should subsequently results in more accurate diagnosis as well as addressing specific markers of potential prognostic and predictive value. AIM: This study was conducted to emphasize the importance of including isocitrate dehydrogenase 1 (IDH1) evaluation as a crucial part of the diagnosis and categorization of high-grade glioma cases. This also may help to individualize the treatment of high-grade glioma patients. MATERIALS AND METHODS: The current study included 60 cases of high-grade gliomas, studied histologically and immunohistochemically for the detection of IDH1 mutation. The results were correlated with different clinicopathologic variables and course of the disease. RESULTS: IDH1 immunohistochemical expression was positive in 46.67% of the studied high-grade glioma cases. A statistically significant relationship was detected between IDH1 expression and tumor histologic grade as 100% of Grade III anaplastic oligodendroglioma cases and 80% of the Grade III anaplastic astrocytoma cases were IDH1 positive while only 40.4% of Grade IV glioblastoma cases were IDH1 positive (p = 0.03). In addition, patients who were IDH1 mutant were in a better category of response to radiotherapy (p = 0.019) and also to chemotherapy (p < 0.001). Moreover, patients who expressed IDH1 had prolonged overall survival (OS) and progression-free survival than those who showed negative IDH1expression (p < 0.001). On the other hand, no statistically significant relationship was detected between IDH1 expression and patients age, sex, tumor site, tumor size, motor symptoms, sensory symptoms, and increased intracranial tension (p > 0.05). CONCLUSIONS: It is suggested that IDH1 is a good prognostic marker for gliomas and is a good predictive marker for response to treatment. IDH1 is a promising target for therapy in high-grade gliomas through the emerging IDH1 inhibitors. Immunohistochemical testing for IDH1 is a practical and cost-effective method that should be applied in all glioma cases. Further study on a larger sample size is recommended to validate the current results. Moreover, applying molecular analysis to detect IDH1 mutation is recommended to be able to precisely detect the IDH1 wild-type tumor

2033 Background: Treatment options for refractory high grade gliomas (HGG) are limited. Programmed cell death ligand-1 (PD-L1) expression has been reported in 0-61% of HGGs and therefore might be a suitable target in HGG. The purpose of this study was to describe safety and efficacy of PD-1 inhibition in patients with refractory HGGs. Methods: This IRB approved single center retrospective study at Memorial Sloan Kettering Cancer Center included pathologically confirmed HGG with an age ≥18 years who received a PD-1 inhibitor between 9/2014 and 10/2016 outside of a clinical trial. Results: Twenty five HGGs were identified. All patients received the PD-1 inhibitor pembrolizumab (pembro) as part of compassionate use. Median age was 49 years (range 30-72); 44% were men; 13 had glioblastoma (52%), 7 anaplastic astrocytoma (28%), 2 anaplastic oligodendroglioma (8%), 2 unspecified HGG (8%), and 1 gliosarcoma (4%). Patients received a median of 4 prior lines of therapy (range 1-9). Nineteen (76%) previously failed bevacizumab. Median baseline KPS was 80 (range 50-100). Concurrent treatment included bevacizumab in 17 (68%) or bevacizumab and temozolomide in 2 (8%) patients. Median number of doses administered was 3 (range 1-14). Treatment toxicity and response was assessed in 24 patients. PD-1 inhibitor related adverse events (AEs) included LFT elevations (33%), hypothyroidism (17%), diarrhea (17%), myalgias/arthralgias (13%), and rash (8%). Other common AEs were hyperglycemia, fatigue, thrombocytopenia, lymphopenia, headache, and nausea in the setting of concomitant therapy and additional supportive care (dexamethasone). Grade 3 AEs included seizure (4%), headache (4%), nausea (4%), and vomiting (4%). Best radiographic response was partial response (n = 2), stable disease (n = 5), and progressive disease (n = 17). Median progression free survival (PFS) was 42 days (range 7-282) and median overall survival was 121 days (range 15-415). Three patients (12%) had a PFS > 90 days; of these, 2 received single agent pembro. Conclusions: Patients with HGG had low response rates. However, a small number of patients had prolonged PFS. Pembro was tolerated with few serious AEs, even in patients receiving concomitant therapy.

Abstract Background: This study evaluated the outcomes of reirradiation combined with bevacizumab (Bev) for patients with recurrent high-grade gliomas that progressed after treatment with Bev.Methods: Between January 2015 and September 2019, 14 patients who experienced progression after Bev treatment were treated with reirradiation consisting of 25 Gy in five fractions combined with Bev (ReRT/Bev). The isocitrate dehydrogenase (IDH) 1/2 mutation status was analysed by pyrosequencing. Results: The diagnoses of 14 patients at the time of reirradiation included six cases of glioblastoma (GBM) with IDH-wildtype, four cases of GBM with IDH-mutant, one case of anaplastic astrocytoma (AA) with IDH-wildtype, one case of AA with IDH-mutant, and one case of GBM not otherwise specified (NOS), and one case of radiologically diagnosed brainstem glioma. The median overall survival (OS) and progression-free survival (PFS) times with ReRT/Bev were 6.1 months and 3.8 months, respectively. The 6-month OS and PFS rates were 54.5% and 15.7%, respectively. The median OS and PFS did not differ significantly between patients with IDH-wildtype (N=7) and IDH-mutant (N=5) (OS: 7.3 [wildtype] vs 6.0 [mutant] months, p = 0.64; PFS: 3.8 [wildtype] vs 3.7 [mutant] months, p = 0.56). The median OS and PFS did not differ significantly between patients with a diagnosis of GBM (N=6) and those with a diagnosis of non-GBM (N=7) (OS: 9.3 [GBM] vs 6.0 [non-GBM] months, p = 0.19; PFS: 4.0 [GBM] vs 3.8 [non-GBM] months, p = 0.31). Four patients (28.6%) achieved a complete or partial radiological response and three patients (21.4%) experienced improvement after ReRT/Bev. Tumor recurrences were observed in 12 patients, including 3 (21.4%) in-field recurrence; 5 (35.7%) marginal recurrence, 3 (21.4%) out-field recurrence, and 1 (7.1%) had in-field and out-field recurrence. Grade 3/4 toxicities included leukopenia in four patients (28.6%), hypertension in three (21.4%), proteinuria in one (7.1%), and gastrointestinal haemorrhage in one (7.1%) with ReRT/Bev. Conclusions: ReRT/Bev for patients with high-grade glioma who experienced progression after Bev was effective and involved acceptable toxicities.

2077 Background: High-grade gliomas are generally resistant to modern chemotherapy. In the case of glioblastoma multiforme, median overall survival has been less than 12 months and progression free survival of less than 4 months. For patients with recurrent GBMs, the 6 month progression free survival is 15–20%. The combination of irinotecan and bevacizumab is an active regimen in the treatment of this disease. Herein we report the experiences with this regimen at our institution with the objective of identifying a therapy with a better outcome than historical results. Methods: Single institutional, retrospective review of 27 patients with recurrent or progressive high grade gliomas treated at the Cleveland Clinic Brain Tumor Institute from 7/2005 through 10/2006. Patients had progressed on at least one prior chemotherapy. Patients with prior irinotecan or bevacizumab were excluded. Patients were analyzed on an intention-to-treat basis, and outcomes estimated by the Kaplan-Meier method. Results: The median age of the group was 46 years (range 5–69). The median number of prior therapies was 2 (range 1–10). Twenty of 27 patients have progressed (74%), and 11 of 27 patients have died (41%). Kaplan-Meier estimates for outcomes are summarized in the table . Progression-free survival at 6 months is 46 %, with median of 5.1 months. Overall survival at 6 months is 84%, with median of 12.6 months. In 7 patients, treatment was terminated early prior to progression. Significant toxicities include: one patient who developed hematuria, one patient with deep venous thrombosis and one patient who experienced intracranial hemorrhage. Conclusions: Our experience suggests that the combination of irinotecan and bevacizumab improves the 6-month progression-free survival when compared to historical figures. The rate of severe toxicities is consistent with prior reports and mandates careful selection of patients. Further randomized, phase 3 studies should be done to validate these results.

Abstract Background Mebendazole is an anthelmintic drug introduced for human use in 1971 that extends survival in preclinical models of glioblastoma and other brain cancers. Methods A single center dose escalation and safety study of mebendazole in 24 patients with newly diagnosed high-grade gliomas (HGG) in combination with temozolomide was conducted. Patients received mebendazole in combination with adjuvant temozolomide after completing concurrent radiation plus temozolomide. Dose escalation levels were 25, 50, 100 and 200 mg/kg/day of oral mebendazole. A 15-patient expansion cohort was conducted at the maximum tolerated dose of 200 mg/kg/day. Trough plasma levels of mebendazole were measured at 4, 8 and 16 weeks. Results Twenty-four patients (18 glioblastoma, 6 anaplastic astrocytoma) were enrolled with median age of 49.9 years. Four patients (at 200 mg/kg) developed elevated grade 3 ALT and/or AST after one month, which reversed with lower dosing or discontinuation. Plasma levels of mebendazole were variable but generally increased with dose. Kaplan Meier analysis showed a 21-month median survival with 43% of patients alive at two years and 25% at 3 and 4 years. Median progression free survival (PFS) from the date of diagnosis for 17 patients taking more than one month of mebendazole was 13.1 months (95% Confidence Interval: 8.8 to 14.6 months) but for seven patients who received less than one month of mebendazole PFS was 9.2 months (95% CI: 5.8 -13.0 months). Conclusion Mebendazole at doses up to 200 mg/kg demonstrated long-term safety and acceptable toxicity. Further studies are needed to determine mebendazole’s efficacy in patients with HGG.

The resilience of high-grade gliomas (HGGs) against conventional chemotherapies is due to their heterogeneous genetic landscape, adaptive phenotypic changes, and immune escape mechanisms. Innovative immunotherapies have been developed to counteract the immunosuppressive capability of gliomas. Nevertheless, further research is needed to assess the efficacy of the immuno-based approach. The aim of this study is to review the newest immunotherapeutic approaches for glioma, focusing on the drug types, mechanisms of action, clinical pieces of evidence, and future challenges. A PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis)-based literature search was performed on PubMed/Medline and ClinicalTrials.gov databases using the keywords “active/adoptive immunotherapy,” “monoclonal antibodies,” “vaccine,” and “engineered T cell.”, combined with “malignant brain tumor”, “high-grade glioma.” Only articles written in English published in the last 10 years were selected, filtered based on best relevance. Active immunotherapies include systemic temozolomide, monoclonal antibodies, and vaccines. In several preclinical and clinical trials, adoptive immunotherapies, including T, natural killer, and natural killer T engineered cells, have been shown to be potential treatment options for relapsing gliomas. Systemic temozolomide is considered the backbone for newly diagnosed HGGs. Bevacizumab and rindopepimut are promising second-line treatments. Adoptive immunotherapies have been proven for relapsing tumors, but further evidence is needed.

Development of effective treatments for high-grade glioma (HGG) is hampered by (1) the blood–brain barrier (BBB), (2) an infiltrative growth pattern, (3) rapid development of therapeutic resistance, and, in many cases, (4) dose-limiting toxicity due to systemic exposure. Convection-enhanced delivery (CED) has the potential to significantly limit systemic toxicity and increase therapeutic index by directly delivering homogenous drug concentrations to the site of disease. In this review, we present clinical experiences and preclinical developments of CED in the setting of high-grade gliomas.

High-grade gliomas are the most common and aggressive malignant primary brain tumors. Current therapeutic schemes include a combination of surgical resection, radiotherapy and chemotherapy; even if major advances have been achieved in Progression Free Survival and Overall Survival for patients harboring high-grade gliomas, prognosis still remains poor; hence, new therapeutic options for malignant gliomas are currently researched. Sonodynamic Therapy (SDT) has proven to be a promising treatment combining the effects of low-intensity ultrasound waves with various sound-sensitive compounds, whose activation leads to increased immunogenicity of tumor cells, increased apoptotic rates and decreased angiogenetic potential. In addition, this therapeutic technique only exerts its cytotoxic effects on tumor cells, while both ultrasound waves and sensitizing compound are non-toxic per se. This review summarizes the present knowledge regarding mechanisms of action of SDT and currently available sonosensitizers and focuses on the preclinical and clinical studies that have investigated its efficacy on malignant gliomas. To date, preclinical studies implying various sonosensitizers and different treatment protocols all seem to confirm the anti-tumoral properties of SDT, while first clinical trials will soon start recruiting patients. Accordingly, it is crucial to conduct further investigations regarding the clinical applications of SDT as a therapeutic option in the management of intracranial gliomas.

Abstract Background High-grade gliomas are the most frequently occurring brain tumors and carry unfavorable prognosis. Literature is controversial regarding the effects of surgery on cognitive functions. Methods We analyzed a homogenous population of 30 patients with high-grade glioma who underwent complete resection. Patients underwent extensive neuropsychological analysis before surgery, 7 days after surgery, and approximately 40 days after surgery, before adjuvant treatments. Thirty-four neuropsychological tests were administered in the language, memory, attention, executive functions, and praxis domains. Results The preoperative percentage of patients with impairment in the considered tests ranged from 0% to 53.3% (mean 20.9%). Despite a general worsening at early follow-up, a significant recovery was observed at late follow-up. Preoperative performances in language and verbal memory tasks depended on the joint effect of tumor volume, volume of surrounding edema, and tumor localization, with major deficits in patients with left lateralized tumor, especially insular and temporal. Preoperative performances in attention and constructive abilities tasks depended on the joint effect of tumor volume, volume of surrounding edema, and patient age, with major deficits in patients ≥ 65 years old. Recovery at late follow-up depended on the volume of resected tumor, edema resorption, and patient age. Conclusions Longitudinal neuropsychological performance of patients affected by high-grade glioma depends, among other factors, on the complex interplay of tumor volume, volume of surrounding edema, tumor localization, and patient age. Reported results support the definition of criteria for surgical indication based on the above factors. They may be used to propose more customized surgical, oncological, and rehabilitative strategies.
