What is new and objectives Trends in the care of glioblastoma in actual practice settings are poorly described. In a previous pharmacoepidemiologic study, we highlighted changes in the management of patients with glioblastoma ( GBM) newly diagnosed between 2004 and 2008. Our aim was to complete and to extend the previous report with a study of a cohort of patients diagnosed in 2011 to emphasize the trends in the pharmacotherapy of GBM over the last decade. Methods A single-centre study was undertaken of three historic cohorts of GBM patients newly diagnosed during years 2004, 2008 and 2011 (corresponding to groups 1, 2 and 3, respectively) but limited to patients eligible for radiotherapy after initial diagnosis. The type of medical management was described and compared, as well as overall survival and total cost from diagnosis to death or the last follow-up date. Cost analysis was performed from the French sickness fund perspective using tariffs from 2014. Results Two hundred and seventeen patients (49 in Group 1, 73 in Group 2, 95 in Group 3) were selected with similar baseline characteristics. Fluorescence-guided surgery using 5- ALA was increasingly used over the three periods. There was a strong trend towards broader use of temozolomide radiochemotherapy (39%, 73% and 83% of patients, respectively) as first-line treatment as well as bevacizumab regimen at recurrence (6%, 48% and 58% of patients, respectively). The increase in overall survival between Group 2 and Group 1 was confirmed for patients in Group 3 (17·5 months vs. 10 months in Group 1). The mean total cost per patient was 53368 € in Group 1, 70 201 € in Group 2 and 78355 € in Group 3. Hospital care represented the largest expenditure (75%, 59% and 60% in groups 1, 2 and 3, respectively) followed by chemotherapy drug costs (11%, 30% and 29%, respectively). What is new and conclusion This is the first study to report on changes in the management of GBM in real-life practice. The ten-year study indicates an improvement in overall survival but also an increase in total cost of care. The data should be useful for informing the care of GBM patients in settings similar to ours. [ABSTRACT FROM AUTHOR]

What is known and objective Therapeutic options for the management of glioblastoma ( GBM) have greatly evolved over the last decade with the emergence of new regimens combining radiotherapy plus temozolomide and the use of bevacizumab at recurrence. Our aim was to assess the clinical and economic impacts of those novel strategies in our center. Methods A single-center retrospective chart review was conducted on patients newly diagnosed with a GBM over two periods (year 2004, group 1 or year 2008, group 2) with limitations to those eligible to radiotherapy after initial diagnosis. The type of medical management was described and compared, as well as overall survival and total costs from diagnosis to death or the last follow-up date. Cost analysis was performed under the French Sickness Fund perspective using tariffs from 2012. Results One hundred twenty-two patients were selected (49 in group 1 and 73 in group 2) with similar baseline characteristics within the two groups. Patients from group 2 received more frequently temozolomide radiochemotherapy (71% vs. 39%, P < 0·05) as first-line treatment as well as bevacizumab regimen at recurrence (48% vs. 6%, P < 0·05); the median overall survival was increased between the two periods (respectively 17 vs. 10 months, P < 0·05). The mean total cost per patient was 54 388 € in group 1 and 71 148 € in group 2 ( P < 0·05). Hospital care represented the largest expenditure (76% and 58% in groups 1 and 2 respectively) followed by chemotherapy drugs costs (11% and 30% respectively). The total cost difference between the two groups was explained by the increasing use of temozolomide and bevacizumab. The incremental cost-effectiveness ratio was estimated at 54 355 € per life-year gained. What is new and conclusion As far as we know, this is the first study reporting the total cost of GBM management based on the French perspective, as well as the cost-effectiveness of clinical practices in term of cost per life-year gained. Those novel strategies have contributed to improve overall survival while inducing a substantial, but acceptable, increase of total costs. [ABSTRACT FROM AUTHOR]

Purpose: To analyze the outcomes and predictors in a large series of cerebellar glioblastomas in order to guide patient management., Methods: The French brain tumor database and the Club de Neuro-Oncologie of the Société Française de Neurochirurgie retrospectively identified adult patients with cerebellar glioblastoma diagnosed between 2003 and 2017. Diagnosis was confirmed by a centralized neuropathological review., Results: Data from 118 cerebellar glioblastoma patients were analyzed (mean age 55.9 years, 55.1% males). The clinical presentation associated raised intracranial pressure (50.8%), static cerebellar syndrome (68.6%), kinetic cerebellar syndrome (49.2%) and/or cranial nerve disorders (17.8%). Glioblastomas were hemispheric (55.9%), vermian (14.4%) or both (29.7%). Hydrocephalus was present in 49 patients (41.5%). Histologically, tumors corresponded either to IDH-wild-type or to K27-mutant glioblastomas. Surgery consisted of total (12.7%), subtotal (35.6%), partial resection (33.9%) or biopsy (17.8%). The postoperative Karnofsky performance status was improved, stable and worsened in 22.4%, 43.9% and 33.7% of patients, respectively. Progression-free and overall survivals reached 5.1 months and 9.1 months, respectively. Compared to other surgical strategies, total or subtotal resection improved the Karnofsky performance status (33.3% vs 12.5%, p < 0.001), prolonged progression-free and overall survivals (6.5 vs 4.3 months, p = 0.015 and 16.7 vs 6.2 months, p < 0.001, respectively) and had a comparable complication rate (40.4% vs 31.1%, p = 0.29). After total or subtotal resection, the functional outcomes were correlated with age (p = 0.004) and cerebellar hemispheric tumor location (p < 0.001) but not brainstem infiltration (p = 0.16)., Conclusion: In selected patients, maximal resection of cerebellar glioblastoma is associated with improved onco-functional outcomes, compared with less invasive procedures.

Objective: To describe the main syndrome and clinical course in a large cohort of patients with anti-Ri-associated paraneoplastic neurologic syndrome (Ri-PNS)., Methods: Twenty-year retrospective nationwide study and systematic review of the literature., Results: Thirty-six patients with complete clinical information were identified (median age 66 years, range: 47-87 years). In this French cohort, the majority were women (78%). At onset, 4 main patterns were observed: cerebellar syndrome (39%), isolated tremor (24%), oculomotor disturbances (17%), and other symptoms (19%). Course was multistep for 78% of cases. At the time the disease reached the plateau phase (median 12 weeks, range: 1-64 weeks; 28% >3 months), 24 (67%) showed an overt cerebellar syndrome, which was isolated in 3 patients, and was most frequently (21/24 cases) part of a multisystem neurologic disease. Patients manifested a variety of movement disorders, including myoclonus (33%), dystonia (17%), either cervical or oromandibular, and parkinsonism (17%). Most patients had cancer (92%), mainly breast cancer (n = 22). Misdiagnoses concerned 22% of patients (n = 8) and included atypical parkinsonism (n = 2), MS (n = 2), Bickerstaff encephalitis (n = 1), hyperekplexia (n = 1), vestibular neuritis (n = 1), and functional neurologic disorder (n = 1). Survival at 12 months was 73% (95% CI [0.54-0.85]), at 24 months 62% (95% CI [0.41-0.78]), and at 36 months 47% (95% CI [0.25-0.65]). There was no major clinical difference between cases retrieved from the systematic review of the literature (n = 55) and the French cohort., Conclusions: Ri-PNS is a multisystem neurologic syndrome with prominent cerebellum/brainstem involvement. Opsoclonus-myoclonus is less common than expected, and the disorder can mimic neurodegenerative diseases., (Copyright © 2020 The Author(s).

Background: Glioblastomas (GBMs) induce a peritumoural vasogenic oedema impairing functional status and quality of life. Steroids reduce brain tumour-related oedema but are associated with numerous side-effects. It was reported in a retrospective series that angiotensin receptor blockers might be associated with reduced peritumoural oedema. The ASTER study is a randomised, placebo-controlled trial to assess whether or not the addition of Losartan to standard of care (SOC) can reduce steroid requirement during radiotherapy (RT) in patients with newly diagnosed GBM., Patients and Methods: Patients with a histologically confirmed GBM after biopsy or partial surgical resection were randomised between Losartan or placebo in addition to SOC with RT and temozolomide (TMZ). The primary objective was to investigate the steroid dosage required to control brain oedema on the last day of RT in each arm. The secondary outcomes were steroids dosage 1 month after the end of RT, assessment of cerebral oedema on magnetic resonance imaging, tolerance and survival., Results: Seventy-five patients were randomly assigned to receive Losartan (37 patients) or placebo (38 patients). No difference in the steroid dosage required to control brain oedema on the last day of RT, or one month after completion of RT, was seen between both arms. The incidence of adverse events was similar in both arms. Median overall survival was similar in both arms., Conclusions: Losartan, although well tolerated, does not reduce the steroid requirement in newly diagnosed GBM patients treated with concomitant RT and TMZ.

Objective: The aim of this study was to describe specificities of patients with NMDA receptor antibody (NMDAR-Ab) encephalitis associated with a malignant tumor., Methods: Retrospective observational study of 252 patients with NMDAR-Ab encephalitis of the French Paraneoplastic Neurological Syndrome Reference Center. Patients were classified in three groups: (1) non-malignant ovarian teratomas, (2) malignant ovarian teratomas (immature), and (3) other malignant tumors., Results: Sixty patients (23.8%) had an associated tumor and 15 (6%) were malignant. No particular neurological symptom was observed in these patients. Ovarian teratomas were the most frequent (51 cases) with 6 of them immature (11.8% of teratomas). Nine patients (3.6%) developed other malignant tumors (3 small cell lung carcinomas, 1 uterine adenocarcinoma, 1 prostate adenocarcinoma, 1 Hodgkin lymphoma, 1 pineal dysgerminoma, 1 neuroblastoma and 1 pancreatic neuroendocrine tumor). Among patients with a cancer other than teratoma, 6/9 were elderly patients (median age 65 years, representing 30% of elderly patients with such encephalitis) compared to a median age of 26 years in adult patients included herein. The clinical course was similar in the three groups, other than a higher death rate among patients with malignant tumors (86 versus 2%; p < 0.001) mainly due to tumor progression (5/7 deaths)., Conclusion: Immature ovarian teratomas represent 11.8% of all teratomas in patients with NDMAR-Ab encephalitis. The other malignant tumors are mainly observed in elderly patients. The presence of a malignant tumor does not impact the neurological presentation but is directly associated with a higher risk of death.

The incidence of glioblastoma (GBM) has increased in patients aged 70 years or older, and will continue to grow. Elderly GBM patients have been excluded from most clinical trials; furthermore, optimal care management as well as benefit/risk ratio of GBM treatments are still being debated. This study describes oncological patterns of care, prognostic factors, and survival for patients ≥ 70 years in France. We identified patients over 70 with newly diagnosed and histologically confirmed GBM on data previously published by the French Brain Tumor DataBase. We included 265 patients. Neurological deficits and mental status disorders were the most frequent symptoms. The surgery consisted of resection (RS n = 95) or biopsy (B n = 170); 98 patients did not have subsequent oncological treatment. After surgery, first-line treatment consisted of radiotherapy (RT n = 76), chemotherapy (CT n = 52), and concomitant radiochemotherapy (CRC n = 39). The median age at diagnosis was 76, 74, and 73 years, respectively, for the untreated, B + RT and/or CT, RS ± RT and/or CT groups. Median survival (in days, 95 % CI) with these main strategies, when analyzed according to surgical groups, was: B-CT n = 41, 199[155-280]; B-CRC n = 21, 318[166-480]; B-RT n = 37, 149[130-214]; RS-CT n = 11, 245[211-na]; RS-CRC n = 18, 372[349-593]; RS-RT n = 39, 269[218-343]. This population study for elderly GBM patients is one of the most important in Europe, and could be considered as a historical cohort to compare future treatments. Moreover, we can hypothesize that elderly patients (versus patients <70 years) are undertreated. Karnofsky performance status seems to be the most relevant clinical predictive factor, and RS and CRC have a positive impact on survival for elderly GBM patients in the general population, at least when feasible.

Background: For 60% of acute febrile encephalitis cases, the cause is unknown. Autoantibodies directed against different synaptic proteins or receptors in patients with autoimmune encephalitis have recently been described and could indicate a differential diagnosis of infectious encephalitis., Objective: The aim of this study was to retrospectively investigate the presence of autoantibodies directed against synaptic proteins or receptors in patients with acute febrile encephalitis. Samples were collected in France in 2007 during a national prospective study., Methods: A total of 253 patients with acute febrile encephalitis were enrolled in 2007. Clinical data were collected with a standardized questionnaire. When possible, cerebrospinal fluid CSF was collected and stored at -80 °C. A total of 108 CSF samples were available for retrospective autoantibody screening. Among the 108 patients, infectious etiology had been detected in 38 cases (35%); of these 38 patients, 29 (27%) had viral encephalitis, and 9 (8%) had bacterial encephalitis. No specific diagnosis was indicated for the other 70 patients (65%). Autoantibodies were detected using a cell-based assay in which HEK293 cells were transfected with plasmids coding for different synaptic proteins or receptors., Results: Two patients had anti-NMDA receptor antibodies (NMDAR-Abs), and all patients were negative for anti-Lgi1, CASPR2, GABABR, AMPAR, and mGluR5 antibodies. The two patients with NMDAR-Abs presented neurological and psychiatric symptoms typical of NMDAR-Abs encephalitis., Conclusions: Autoimmune etiology seems to be rare (less than 2%) in patients with acute febrile encephalitis. However, patients should be systematically screened for the presence of NMDAR-Abs, particularly patients presenting with psychiatric symptoms., (Copyright © 2014 The British Infection Association.
