Background Elderly patients with glioblastoma are perceived to face a poor prognosis with perceptions surrounding older age and a relative lack of randomized data contributing. This study evaluated survival prognosticators in elderly glioblastoma patients to more accurately guide their treatment. Materials and methods The records of 169 elderly (≥70 years) patients with a new diagnosis of glioblastoma who had undergone neurosurgical intervention were retrospectively examined for patient sex, age, performance status, comorbidities, MGMT promoter methylation, surgical intervention and chemoradiation regime. The adjusted survival impact of these factors was determined using Cox proportional hazards model and used to devise a two-stage scoring system to estimate patient survival at the stage of surgical (Elderly Glioblastoma Surgical Score, EGSS) and oncological management (Elderly Glioblastoma Oncological Score, EGOS). Results The median overall survival (mOS) of the cohort was 28.8 weeks. Gross-total and subtotal resection were associated with improved survival compared to biopsy alone (respective mOS 65.3 and 28.1 vs 15.7 weeks, p<0.001). Hypofractionated radiotherapy (40Gy in 15 fractions) with Temozolomide was non-inferior to the Stupp protocol, p=0.72. Exploratory subgroup analysis revealed a significant benefit of Temozolomide-based approaches in MGMT-methylated patients as well as a trend towards improved survival in MGMT-unmethylated patients. Our EGSS and EGOS scores successfully estimated survival in this retrospective cohort with 65% and 73% accuracy. Conclusions Where appropriate and safe, elderly glioblastoma patients may benefit from surgical resection and combined chemoradiotherapy with Temozolomide. The proposed EGSS and EGOS scores take into account important prognostic factors to help guide which patients should receive such treatment.

Background Glioblastoma (GB) is the most common intrinsic brain cancer and notorious for its aggressive nature. Despite widespread research and optimization of clinical management, the improvement in overall survival has been limited. The aim of this study was to characterise the impact of service reconfiguration on GB outcomes in a single centre. Methods Patients with a histopathological confirmation of diagnosis of GB between 01/01/2014 and 31/12/2019 were retrospectively identified. Demographic and tumour characteristics, survival, treatment (surgical and oncological), admission status, use of surgical adjunct (5-aminolevulinic acid, intra-operative neuro-monitoring), length of stay, extent of resection, and surgical complications were recorded from the hospital databases. Results From August 2018 the neurosurgical oncology service was reconfigured to manage high grade tumours on an urgent outpatient basis by surgeons specialising in oncology. We demonstrate that these changes resulted in an increase of elective admissions, greater use of intra-operative adjuncts resulting in improved extent of tumour resection, and reduction in median length of stay and associated cost-savings. Conclusions Optimising neuro-oncology patient management through service reconfiguration resulted in increased use of intra-operative adjuncts, improved surgical outcomes, and reduced hospital costs. These changes also have the potential to improve survival and disease-free progression for patients with GB.
Introduction: Malignant gliomas refer to grade III or IV brain tumors defined according to the World Health Organization (WHO) classification. They are a heterogeneous group of pathologies and represent a serious health problem by their frequency, severity and treatment difficulties. The prognosis of malignant gliomas remains poor despite all the medical advances. Materials and Methods: It is a retrospective study included 20 cases of malignant glial tumors treated at the medical oncology department, Fattouma Bourguiba hospital in Monastir between 2012 and 2016, according to the STUPP protocol. Results: These were 12 men and 8 women with a median age of 43. Clinical signs were not very specific, dominated by intracranial hypertension and deficit signs. Imagery referred to the diagnosis of malignant gliomas in 1st intention. Surgery consisted of a macroscopically complete exeresis in (15%) cases, a partial exeresis in (50%), the rest of the patients had a stereotactic biopsy. Histology found GBM in 16 patients (80%), 2 cases of Grade III anaplastic astrocytoma (10%), 1 case of anaplastic oligodendroglioma (5%), and 1 case of Grade III anaplastic eppendymoma (5%). Most of our patients received concurrent radio-chemotherapy and adjuvant TMZ chemotherapy was administered in 15 patients, 7 of whom received the full 6 scheduled cures. A relapse treatment was decided in only one of the 12 patients who relapsed. 6 patients are still alive. The median survival is 11.27 months. In our series, overall survival was related to histological type (p = 0.006) and neurological status assessed at the end of RT-CT (p = 0.001). While age, general condition score, type of surgery, and post-therapeutic development did not show a sta-
