Intracranial metastasis from prostate cancer is rare. As treatment of castration-resistant prostate cancer improves, the incidence of men with intracranial metastasis from prostate cancer is increasing. Radiation therapy for treatment of intracranial metastasis from prostate cancer is systematically reviewed. A comprehensive review examining peer-reviewed, English language articles from 1990 to 2015 was performed on multiple databases, yielding 1274 articles. These articles were reviewed and selected for studies that met the following inclusion criteria: (1) patients with intracranial metastases from prostate cancer; (2) patients underwent radiation therapy as primary or adjuvant therapy; (3) the sample size of patients was larger than 2...

This study was designed to investigate the impact of interim progression of disease (PD) during the surgery-to-radiotherapy interval (SRI) and its predictors in glioblastoma based on MRIs. A total of 222 patients were planned for radiotherapy (RT) and 166 of them were evaluable for the presence of interim PD by 2 separate MRIs. The size criteria from the updated Response Assessment in Neuro-Oncology criteria was adopted to determine interim PD. 32 (19.3%) patients experienced interim PD, and their median survival (MS) was shorter than patients without PD in univariate (11...

The value of perfusion and diffusion-weighted MRI in differentiating histological subtypes according to the 2007 WHO glioma classification scheme (i.e. astrocytoma vs. oligodendroglioma) and genetic subtypes according to the 2016 WHO reclassification (e.g. 1p/19q co-deletion and IDH1 mutation status) in WHO grade II and III diffuse gliomas remains controversial. In the current study, we describe unique perfusion and diffusion MR signatures between histological and genetic glioma subtypes. Sixty-five patients with 2007 histological designations (astrocytomas and oligodendrogliomas), 1p/19q status (+ = intact/- = co-deleted), and IDH1 mutation status (MUT/WT) were included in this study...

Patients with head and neck malignancies commonly develop metastatic disease, yet rarely do these carcinomas metastasize to the brain. Stereotactic radiosurgery (SRS) is routinely employed to treat brain metastases (BM). This study was undertaken to examine the efficacy of SRS for BM from primary head and neck carcinomas. From 2000 to 2016, a total of 19 patients with 38 lesions were retrospectively identified. All patients presented with a primary head and neck malignancy and subsequently developed metastatic disease to the brain treated with SRS at our institution...

Meningiomas are primary intracranial tumors that are often asymptomatic. To our knowledge, no study has attempted to describe neurocognitive function in patients with incidentally-discovered meningioma. We utilized the Mayo Clinic Study of Aging (MCSA), which is a population-based sample of Olmsted County, Minnesota residents that includes neuropsychological testing and brain MRI approximately every 15 months. Using a text search of radiologists' notes of 2402 MCSA individuals (mean age 77 years, scanned between 2004 and 2014) we identified 48 eligible subjects (2%) who had at least one meningioma...

Fatigue is the most prevalent and disabling symptom in cancer patients. Yet, scientific literature on this topic is scarce and reports disparate results. This study systematically reviews how fatigue is assessed in patients with low-grade glioma and evaluates its prevalence in LGG patients. A systematic literature search was performed in PubMed, Embase and PsychINFO for articles reporting on fatigue in patients with LGG. Two reviewers independently extracted data from selected articles. Inclusion criteria were: (1) patients with suspected or confirmed LGG; (2) fatigue was assessed as primary or secondary outcome measure; (3) age≥ 18 years; (4) full-length article written in English or Dutch...

The goal of this study was to investigate the impact of patient-, disease-, and treatment-related variables upon neurocognitive outcomes in pediatric patients with craniopharyngioma prior to treatment with proton therapy or observation after radical resection. For all participants (N = 104), relevant clinical and demographic variables were attained and neurocognitive evaluations completed prior to irradiation or planned observation. One-sample t-tests were conducted to compare performance to published normative data...

High-grade gliomas are aggressive and intensely glycolytic tumors. In the present study, we evaluated the mitochondrial respiratory function of glioma cells (T98G and U-87MG) and fresh human glioblastoma (GBM) tissue. To this end, measurements of oxygen consumption rate (OCR) were performed under various experimental conditions. The OCR of T98G and U-87MG cells was well coupled to ADP phosphorylation based on the ratio of ATP produced per oxygen consumed of ~2.5. In agreement, the basal OCR of GBM tissue was also partially associated with ADP phosphorylation...

Leptomeningeal disease (LMD) is well described in patients with brain metastases, presenting symptomatically in approximately 5% of patients. Conventionally, the presence of LMD is an indication for whole brain radiation therapy (WBRT) and not suitable for stereotactic radiosurgery (SRS). The purpose of the study was to evaluate the local control and overall survival of patients who underwent SRS to focal LMD. We reviewed our prospective registry and identified 32 brain metastases patients with LMD, from a total of 465 patients who underwent SRS between 2013 and 2015...

We conducted this study to determine whether the methylation status of the O(6)-methylguanine-DNA methyltransferase (MGMT) promoter was a prognostic marker for positive outcomes of gamma knife radiosurgery (GKS) for recurrent glioblastoma (GBM). We retrospectively examined 61 patients, who underwent GKS for local recurrent GBM between 2004 and 2015; in all patients, the methylation status of the MGMT promoter was identified via methylation-specific quantitative real-time polymerase chain reaction. All patients underwent surgical resection and were diagnosed histopathologically with GBM...

Skull base meningiomas may present as clinically aggressive tumors despite being histologically benign. Here we describe a clinico-radiological entity of diffuse midline skull base meningiomas responsible for several neurological morbidities, including hearing and vision loss, intracranial hypertension, secondary hydrocephalus and tonsillar herniation with spinal cord compression. Surgery and radiotherapy were ineffective in stopping the clinical course of those tumors. After targeted sequencing of known mutated genes in meningiomas, we discovered TRAF7 mutations in two out of four tumors, stressing the importance of focusing the research efforts of the meningioma community in understanding the mechanisms underlying TRAF7 related meningioma tumorigenesis...

Medulloblastoma patients are treated with surgery, radiation and chemotherapy. Radiation dose to the temporal lobe may be associated with neurocognitive sequelae. Longitudinal changes of temporal lobe cortical thickness may result from neurodevelopmental processes such as synaptic pruning. This study applies longitudinal image analysis to compare developmental change in cortical thickness in medulloblastoma (MB) patients who were treated by combined modality therapy to that of cerebellar juvenile pilocytic astrocytoma (JPA) patients who were treated by surgery alone...

In recurrent glioblastoma, health-related quality of life (HRQL) is a crucial trial endpoint. We examined HRQL outcomes as a secondary endpoint for patients in the CABARET randomized phase 2 trial. 122 patients were randomly allocated to bevacizumab monotherapy or bevacizumab plus carboplatin. We calculated change scores from baseline for each HRQL measure on the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) and the Brain Cancer Module (QLQ-BN20), together with time to deterioration in HRQL, and the proportion of participants with clinically meaningful improvements in specific disease-related symptoms...

We have used boron neutron capture therapy (BNCT) to treat patients in Japan with newly diagnosed or recurrent high-grade gliomas and have observed a significant increase in median survival time following BNCT. Although cerebrospinal fluid dissemination (CSFD) is not usually seen with the current standard therapy of patients with glioblastoma (GBM), here we report that subarachnoid or intraventricular CSFD was the most frequent cause of death for a cohort of our patients with high-grade gliomas who had been treated with BNCT...

Carmustine wafers (CW) were approved in Japan for newly diagnosed and recurrent malignant gliomas during 2013. The ventricle is often opened during surgery to achieve maximum resection. While not generally recommended in such situations, CW might be safely achieved by occluding an opened ventricle using gelform or collagen sheets. However, whether CW implantation actually confers a survival benefit for patients who undergo surgery with an open ventricle to treat glioblastoma remains unclear. Clinical, imaging, and survival data were collected in this multicenter retrospective study of 122 consecutive patients with newly diagnosed glioblastoma to determine adverse events and efficacy...

Subependymoma is a rare primary brain tumor, constituting 0.07-0.51% of brain tumors. Genetic alterations in subependymoma are largely unknown, but familial occurrences have been reported. Trichorhinophalangeal syndrome type 1 (TRPS1) is a rare hereditary malformation complex caused by mutations in a gene identified in the year 2000 on 8q24.12. We report two patients with TRPS I and surgically treated subependymomas, one of whom has a first degree relative, now deceased, who was affected and also had a subependymoma...

5-Aminolevulinic acid (5-ALA) fluorescence-guided surgery is widely used for detection and planning of resection of malignant gliomas and other brain tumors. However, no reports have described 5-ALA fluorescence-guided surgery or direct visualization of germ cell tumors. Here, we report two cases of germ cell tumors in which a positive 5-ALA fluorescent signal was visualized with a neuroendoscope. Both cases had a tumor in the pineal region that was associated with hydrocephalus. The patients underwent surgery after administration of 5-ALA...
