Randomized Controlled Trial Multicenter StudyDo statins, ACE inhibitors or sartans improve outcome in primary glioblastoma?
Glioblastomas are malignant brain tumors with poor prognosis. Lately, data from clinical studies assessing the role of co-medications in different cancer types suggested reduced mortality and potential anti-tumor activity for statins, angiotensin-I converting enzyme inhibitors (ACEI) and angiotensin II receptor blockers (sartans). Here, we analysed the association of co-treatment with statins, ACEI or sartans with outcome in a cohort of 810 patients enrolled in the phase III CENTRIC and phase II CORE trials on the role of the integrin antagonist, cilengitide, in newly diagnosed glioblastoma with or without O6-methylguanine DNA methyltransferase (MGMT) promoter methylation. ⋯ RT + CIL + TMZ → TMZ + CIL). This secondary analysis of two large glioblastoma trials thus was unable to detect evidence for an association of the use of statins, ACEI or sartans with outcome in patients with newly diagnosed glioblastoma. These data challenge the rationale for prospective studies on the possible role of these non-tumor-specific drugs within the concept of drug repurposing.

Multicenter StudyEnd-of-life care of children with diffuse intrinsic pontine glioma.
The end-of-life management of children with diffuse intrinsic pontine glioma (DIPG) is challenging. Families cope with debilitating symptoms and make complex decisions regarding their child's care. However, there is little evidence guiding palliative care provision for these children. ⋯ Children with DIPG have complex needs and require intensive multidisciplinary support. This paper describes the end-of-life choices made for these children and discusses how these choices influence our institutional model for palliative care. We believe this approach will be useful to clinicians caring for similar patients.

Standard dose and dose-escalated radiation therapy are associated with favorable survival in select elderly patients with newly diagnosed glioblastoma.
We hypothesized elderly patients with good Karnofsky Performance Status (KPS) treated with standard dose or dose-escalated radiation therapy (SDRT/DERT) and concurrent temozolomide (TMZ) would have favorable overall survival (OS) compared to historical elderly patients treated with hypofractionated RT (HFRT). From 2004 to 2015, 66 patients age ≥ 60 with newly diagnosed, pathologically proven glioblastoma were treated with SDRT/DERT over 30 fractions with concurrent/adjuvant TMZ at a single institution. Kaplan-Meier methods and the log-rank test were used to assess OS and progression-free survival (PFS). ⋯ On MVA controlling for age, dose, KPS, MGMT, GTR, and adjuvant TMZ, younger age (HR 0.9, 95% CI 0.8-0.9, p < 0.01), MGMT methylation (HR:0.2, 95% CI 0.1-0.7, p = 0.01), and GTR (HR:0.5, 95% CI 0.3-0.9, p = 0.01) were associated with improved OS. Our findings do not support routine use of a standard 6-week course of radiation therapy in elderly patients with glioblastoma. However, a select group of elderly patients with excellent performance status and MGMT methylation or GTR may experience favorable survival with a standard 6-week course of treatment.

Surgical treatment of glioblastoma in the elderly: the impact of complications.
The diagnosis of glioblastoma (GBM) often carries a dismal prognosis, with a median survival of 14.6 months. A particular challenge is the diagnosis of GBM in the elderly population (age > 75 years), who have significant comorbidities, present with worse functional status, and are at higher risk with surgical treatments. We sought to evaluate the impact of current GBM treatment, specifically in the elderly population. ⋯ The benefit of glioblastoma treatment in our series was limited by the postoperative complications and KPS. Presence of a complication served as an independent risk factor for worsened overall survival in this age group. It is likely that decreased patient function limits postoperative adjuvant therapy and predisposes to higher morbidity especially in this age group.
