Super-early initiation of temozolomide prolongs the survival of glioblastoma patients without gross-total resection: a retrospective cohort study.
The optimal timing of chemoradiotherapy in patients with newly diagnosed glioblastoma (GBM) remains unclear. In this study, we explored the clinical efficacy of super-early initiation of temozolomide (TMZ) in the treatment interval from surgery to radiotherapy. ⋯ This retrospective study highlights that super-early initiation of TMZ in newly diagnosed GBM may confer to survival benefit, especially for those without GTR.

Health-related quality of life of patients with brain metastases selected for stereotactic radiosurgery.
Information on health-related quality of life (HRQoL) of patients with brain metastases (BM) before stereotactic radiosurgery (SRS) is very relevant to improve communication between patients and clinicians and to be able to interpret changes in HRQoL after SRS. The aim of this study was to evaluate the prevalence and severity of complaints on different aspects of pre-SRS HRQoL among patients with BM and to identify predictors thereof. ⋯ An increased understanding of pre-SRS HRQoL and predictors hereof, provides us with more insight into the well-being of our patients with BM and is necessary for the interpretation of (changes in) HRQoL after SRS.

Review Meta AnalysisHypofractionated versus standard radiation therapy in combination with temozolomide for glioblastoma in the elderly: a meta-analysis.
There is no clear consensus regarding the optimal treatment for glioblastoma (GBM) in the elderly. Hypofractionated radiation therapy (hRT) has emerged as a viable and comparable radiation regime compared to standard radiation therapy (sRT), however the survival effect of temozolomide (TMZ) with hRT is uncertain. The aim of this meta-analysis was to evaluate survival outcomes of hRT + TMZ vs sRT + TMZ in this specific demographic. ⋯ The combination of hRT + TMZ is feasible in well-selected elderly GBM cases, and appears to confer a statistically comparable PFS compared to sRT + TMZ. However, expectations that the OS with hRT + TMZ is comparable to that of sRT + TMZ in all elderly GBM presentations should be tempered. It is likely a specific subgroup of elderly GBM patients will benefit greatly from the addition of TMZ to hRT, and greater investigation is needed to identify their characteristics.

Awake craniotomies for epileptic gliomas: intraoperative and postoperative seizure control and prognostic factors.
Awake craniotomy is well-established for tumors resected in eloquent brain areas. Whether awake craniotomy provides improved seizure control in patients with epileptic gliomas has not been well evaluated. This study analyzed the incidence, risk factors and outcome of seizures during and following awake craniotomies for patients presenting with epilepsy and glioma. ⋯ Intraoperative seizures could be well-controlled during awake craniotomies. Early postoperative seizures extended hospitalization and strongly predicted late seizure recurrence. Awake craniotomies benefited long-term seizure control in patients with epileptic gliomas.

NRG brain tumor specialists consensus guidelines for glioblastoma contouring.
NRG protocols for glioblastoma allow for clinical target volume (CTV) reductions at natural barriers; however, literature examining CTV contouring and the relevant white matter pathways is lacking. This study proposes consensus CTV guidelines, with a focus on areas of controversy while highlighting common errors in glioblastoma target delineation. ⋯ Consensus contouring guidelines were established based on expert contours. Careful delineation of anatomic pathways and barriers to spread can spare radiation to uninvolved tissue without compromising target coverage. Further study is necessary to accurately define optimal target volumes beyond isometric expansion techniques for individual patients.
