Standard 6-week chemoradiation for elderly patients with newly diagnosed glioblastoma.

Glioblastoma (GBM) is frequent in elderly patients, but their frailty provokes debate regarding optimal treatment in general, and the standard 6-week chemoradiation (CRT) in particular, although this is the mainstay for younger patients. All patients with newly diagnosed GBM and age ≥ 70 who were referred to our institution for 6-week CRT were reviewed from 2004 to 2018. MGMT status was not available for treatment decision at that time. The primary endpoint was overall survival (OS). Secondary outcomes were progression-free survival (PFS), early adverse neurological events without neurological progression ≤ 1 month after CRT and temozolomide hematologic toxicity assessed by CTCAE v5. 128 patients were included. The median age was 74.1 (IQR: 72-77). 15% of patients were ≥ 80 years. 62.5% and 37.5% of patients fulfilled the criteria for RPA class I-II and III-IV, respectively. 81% of patients received the entire CRT and 28% completed the maintenance temozolomide. With median follow-up of 11.7 months (IQR: 6.5-17.5), median OS was 11.7 months (CI 95%: 10-13 months). Median PFS was 9.5 months (CI 95%: 9-10.5 months). 8% of patients experienced grade ≥ 3 hematologic events. 52.5% of patients without neurological progression had early adverse neurological events. Post-operative neurological disabilities and age ≥ 80 were not associated with worsened outcomes. 6-week chemoradiation was feasible for "real-life" elderly patients diagnosed with glioblastoma, even in the case of post-operative neurological disabilities. Old does not necessarily mean worse.

Long-Term Follow-Up Comparative Study of Hydroxyapatite and Autologous Cranioplasties: Complications, Cosmetic Results, Osseointegration.

OBJECTIVE: A three-dimensional reconstruction technique using the CustomBone (CB) prosthesis allows custom-made cranioplasty (CP) possessing osseointegration properties owing to its porous hydroxyapatite (HA) composition. This reconstruction technique has replaced less expensive techniques such as subcutaneously preserved autologous bone (SP). Our primary objective was to evaluate complications between CB and SP CP techniques. A secondary objective was to assess cosmetic results and osseointegration of CPs. METHODS: This single-center study comprised patients undergoing delayed CB or SP CP after craniectomy between 2007 and 2014. A prospective interview was conducted to collect all data, including 2-year follow-up clinical and radiologic data. Cosmetic results were assessed by a qualitative score, and osseointegration was assessed by measuring relative fusion at the CP margins. RESULTS: Of 100 patients undergoing CB or SP CP between 2007 and 2014, 92 (CB, n = 44; SP, n = 48) participated in the prospective interview. No significant difference in complication rates was observed between the 2 groups. The main complication specific to the CB group was fracture of the prosthesis observed in 20.8% patients. A higher rate of good cosmetic results was observed in the CB group (92.5% vs. 74.3%, P = 0.031). In the CB group, 51% of patients demonstrated no signs of bone fusion of the CP. CONCLUSIONS: Although the CB prosthesis is associated with cosmetic advantages, the porous hydroxyapatite composition makes it fragile in the short-term and long-term, and effective osseointegration remains uncertain.

Understanding the Pathophysiology of Intracranial Aneurysm: The ICAN Project.

BACKGROUND: Understanding the pathophysiologic mechanism of intracranial aneurysm (IA) formation is a prerequisite to assess the potential risk of rupture. Nowadays, there are neither reliable biomarkers nor diagnostic tools to predict the formation or the evolution of IA. Increasing evidence suggests a genetic component of IA but genetics studies have failed to identify genetic variation causally related to IA. OBJECTIVE: To develop diagnostic and predictive tools for the risk of IA formation and rupture. METHODS: The French ICAN project is a noninterventional nationwide and multicentric research program. Each typical IA of bifurcation will be included. For familial forms, further IA screening will be applied among first-degree relatives. By accurate phenotype description with high-throughput genetic screening, we aim to identify new genes involved in IA. These potential genetic markers will be tested in large groups of patients. Any relevant pathway identified will be further explored in a large cohort of sporadic carriers of IA, which will be well documented with clinical, biological, and imaging data. EXPECTED OUTCOMES: Discovering genetic risk factors, better understanding the pathophysiology, and identifying molecular mechanisms responsible for IA formation will be essential bases for the development of biomarkers and identification of therapeutic targets. DISCUSSION: Our protocol has many assets. A nationwide recruitment allows for the inclusion of large pedigrees with familial forms of IA. It will combine accurate phenotyping and comprehensive imaging with high-throughput genetic screening. Last, it will enable exploiting metadata to explore new pathophysiological pathways of interest by crossing clinical, genetic, biological, and imaging information.

Management of aneurysmal subarachnoid haemorrhage with intracerebral hematoma: Is there an indication for coiling first? Study of 44 cases.

BACKGROUND: Aneurysmal subarachnoid haemorrhage (ASH) with intracerebral hematoma (ICH) has a poor prognosis. The treatment is to secure the aneurysm and do an ICH evacuation. OBJECTIVE: The aim of the study was to determine if aneurysm coiling followed by ICH evacuation is a viable alternative treatment compared to exclusive surgery, regardless of the clinical or paraclinical presentations. METHODS: A retrospective study was conducted between 2004 and 2014, which included 44 patients. The patients were divided up in four groups. Two were principal groups: The clipped group (aneurysm clipping with ICH evacuation) and the coiled group (aneurysm coiling, followed by ICH evacuation); and two were subgroups of the latter: Aneurysm coiling with ICH evacuation after 24 hours and ICH evacuation followed by aneurysm coiling. We studied the demographic and radiologic characteristics, and the 3-month outcome. RESULTS: We included 17 patients in the coiled group: The outcome was better for the patients with World Federation of Neurosurgery (WFNS) scores of 1, 2 and 3; compared to the patients with WFNS scores 4 and 5. We included 16 patients in the clipped group: The outcome was better, compared the coiled group, for those patients with WFNS scores 4 and 5. Six patients were treated with aneurysm coiling, followed by ICH evacuation after 24 hours: 33% had a good outcome. Five patients were treated by ICH evacuation, followed by aneurysm coiling: None had a good outcome. CONCLUSIONS: It was necessary to realise a prospective study to compare the outcomes of patients with WFNS scores of 1, 2 or 3; between those with aneurysm coiling followed by ICH evacuation and aneurysm clipping with ICH evacuation, to determine the potential of using the coiling first, for these patients.

Intracranial meningioma surgery in the ninth decade of life.

OBJECTIVE: The aims of this study are to assess the surgical outcome of elderly patients aged 80 years or more, to analyze the factors influencing postoperative course, and to propose a grading system to standardize the surgical indication of intracranial meningioma in the elderly. METHODS: Between 1990 and 2005, we surgically treated 74 consecutive patients aged 80 years or more for intracranial meningiomas (47 women, 27 men; mean age, 82 yr; age range, 80-90 yr). The median follow-up period was 94 months (range, 15-147 mo). We retrospectively analyzed the factors influencing surgical outcome and retained the significant factors to form the Sex, Karnofsky Performance Scale, American Society of Anesthesiology Class, Location of Tumor, and Peritumoral Edema (SKALE) grading system. RESULTS: There was no perioperative mortality, and the 1-year mortality rate was 9.4%. Postoperative mortality was lower in women with a Karnofsky Performance Scale score of 60 or greater, an American Society of Anesthesiology Class of 1 or 2, a noncritical tumor location, and a moderate or absent peritumoral edema. Patients with a SKALE score of more than 8 had an excellent outcome, whereas those with a SKALE score of less than 8 had a poor outcome. The rate of postoperative complications was 9.4%. Large tumors, critical locations, severe peritumoral edema, and total surgical excision were associated with a higher risk of postoperative complications. CONCLUSION: Surgery of intracranial meningioma in elderly patients is feasible when the SKALE score is 8 or greater. Prospective studies are required to validate this grading system.
