Indian Ayurvedic medicine: Overview and application to brain cancer.

Ayurveda is the traditional medicine system of India, and has been in practice for millennia. It is a traditional approach that uses 1000's of different plant preparations in various combinations for treatment of human ailments, including cancer. Ethnopharmacological and phytochemical analyses are now elucidating the bioactive constituents of the different plant species and herbal formulations, including ashwagandha, curcumin, guduchi, triphala, and others.

Antiepileptic Strategies for Patients with Primary and Metastatic Brain Tumors.

Seizure activity is common in patients with primary and metastatic brain tumors, affecting more than 50% of cases over the course of their disease. Several mechanisms contribute to brain tumor-related epilepsy (BTRE), including a pro-inflammatory environment, excessive secretion of glutamate and an increase in neuronal excitatory tone, reduction of GABAergic inhibitory activity, and an increase in 2-hydroxygluturate production in isocitrate dehydrogenase mutant tumors. After a verified seizure in a brain tumor patient, the consensus is that BTRE has developed, and it is necessary to initiate an antiepileptic drug (AED).

Successful Intrathecal Rituximab Administration in Refractory Nonteratoma Anti-N-Methyl-D-Aspartate Receptor Encephalitis: A Case Report.

N-methyl-D-aspartate receptor (NMDA-R) antibody encephalitis is an immune-mediated disorder characterized by the presence of anti-NMDA antibody in serum and cerebrospinal fluid, with a characteristic combination of psychological and neurological signs and symptoms. The scientific knowledge pertaining to the management of anti-NMDA-R encephalitis is growing. It is important that neuroscience nurses be aware of treatments as well as the newest novel treatment options available.

Phase II multicenter study of gene-mediated cytotoxic immunotherapy as adjuvant to surgical resection for newly diagnosed malignant glioma.

Background: Despite aggressive standard of care (SOC) treatment, survival of malignant gliomas remains very poor. This Phase II, prospective, matched controlled, multicenter trial was conducted to assess the safety and efficacy of aglatimagene besadenovec (AdV-tk) plus valacyclovir (gene-mediated cytotoxic immunotherapy [GMCI]) in combination with SOC for newly diagnosed malignant glioma patients.

Methods: Treatment cohort patients received SOC + GMCI and were enrolled at 4 institutions from 2006 to 2010.

Central Nervous System Cancers, Version 1.2015.

The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Central Nervous System (CNS) Cancers provide interdisciplinary recommendations for managing adult CNS cancers. Primary and metastatic brain tumors are a heterogeneous group of neoplasms with varied outcomes and management strategies. These NCCN Guidelines Insights summarize the NCCN CNS Cancers Panel's discussion and highlight notable changes in the 2015 update.

Survival outcomes and safety of carmustine wafers in the treatment of high-grade gliomas: a meta-analysis.

Carmustine wafers (CW; Gliadel(®) wafers) are approved to treat newly-diagnosed high-grade glioma (HGG) and recurrent glioblastoma. Widespread use has been limited for several reasons, including concern that their use may preclude enrollment in subsequent clinical trials due to uncertainty about confounding of results and potential toxicities. This meta-analysis estimated survival following treatment with CW for HGG.

Efficacy and patient-reported outcomes with dose-intense temozolomide in patients with newly diagnosed pure and mixed anaplastic oligodendroglioma: a phase II multicenter study.

Standard initial therapy for patients with pure and mixed anaplastic oligodendrogliomas (AO/MAO) includes chemotherapy and radiation therapy. Anaplastic oligodendrogliomas with 1p/19q co-deletion are more responsive to chemotherapy. There is concern for potential long-term CNS toxicity of radiation.

Central nervous system cancers, version 2.2014. Featured updates to the NCCN Guidelines.

The NCCN Guidelines for Central Nervous System Cancers provide multidisciplinary recommendations for the clinical management of patients with cancers of the central nervous system. These NCCN Guidelines Insights highlight recent updates regarding the management of metastatic brain tumors using radiation therapy. Use of stereotactic radiosurgery (SRS) is no longer limited to patients with 3 or fewer lesions, because data suggest that total disease burden, rather than number of lesions, is predictive of survival benefits associated with the technique.

Neurosarcoidosis: clinical review of a disorder with challenging inpatient presentations and diagnostic considerations.

Neurosarcoidosis is frequently on the differential diagnosis for neurohospitalists. The diagnosis can be challenging due to the wide variety of clinical presentations as well as the limitations of noninvasive diagnostic testing. This article briefly touches on systemic features that may herald suspicion of this disorder and then expands in depth on the neurological clinical presentations.

Central nervous system cancers.

Primary and metastatic tumors of the central nervous system are a heterogeneous group of neoplasms with varied outcomes and management strategies. Recently, improved survival observed in 2 randomized clinical trials established combined chemotherapy and radiation as the new standard for treating patients with pure or mixed anaplastic oligodendroglioma harboring the 1p/19q codeletion. For metastatic disease, increasing evidence supports the efficacy of stereotactic radiosurgery in treating patients with multiple metastatic lesions but low overall tumor volume.

"Tumoral pseudoblush" identified within gliomas at high-spatial-resolution ultrahigh-field-strength gradient-echo MR imaging corresponds to microvascularity at stereotactic biopsy.

Purpose: To use directed biopsy sampling to determine whether microvascular assessment within gliomas, by means of ultrahigh-field-strength high-spatial-resolution gradient-echo (GRE) magnetic resonance (MR) imaging at 8 T, correlates with histopathologic assessment of microvascularity.

Materials And Methods: The study was institutional review board approved and HIPAA compliant. Informed consent was obtained.

Neurological complications of chemotherapy to the central nervous system.

One of the most common complications of chemotherapeutic drugs is toxicity to the central nervous system (CNS). This toxicity can manifest in many ways, including encephalopathy syndromes and confusional states, seizure activity, headache, cerebrovascular complications and stroke, visual loss, cerebellar dysfunction, and spinal cord damage with myelopathy. For many drugs, the toxicity is related to route of administration and cumulative dose, and can vary from brief, transient episodes to more severe, chronic sequelae.

Bevacizumab for glioblastoma refractory to vascular endothelial growth factor receptor inhibitors.

Glioblastoma (GBM) is a highly vascular tumor dependent on angiogenesis through the vascular endothelial growth factor (VEGF) signaling cascade. Inhibition of VEGF signaling is an important therapeutic strategy. We report our experience with bevacizumab (BEV), a VEGF targeting antibody, following failure of a VEGF receptor targeting tyrosine kinase inhibitor (TKI).

Emergent pulmonary embolectomy and advanced glioblastoma multiforme.

Pulmonary emboli are frequent causes of morbidity and mortality in patients with brain tumors. Treatment options are limited in these complex patients. We report a case of successful acute pulmonary embolectomy in a patient with an advanced brain cancer.

Clinical presentation, histology, and treatment in 430 patients with primary tumors of the spinal cord, spinal meninges, or cauda equina.

OBJECT Patients having a primary tumor of the spinal cord, spinal meninges or cauda equina, are relatively rare. Neurosurgeons encounter and treat such patients, and need to be aware of their clinical presentation, tumor types, treatment options, and potential complications. The purpose of this paper is to report results from a series of 430 patients with primary intraspinal tumors, taken from a larger cohort of 9661 patients with primary tumors of the CNS.

Targeting of the Bmi-1 oncogene/stem cell renewal factor by microRNA-128 inhibits glioma proliferation and self-renewal.

MicroRNAs (miR) show characteristic expression signatures in various cancers and can profoundly affect cancer cell behavior. We carried out miR expression profiling of human glioblastoma specimens versus adjacent brain devoid of tumor. This revealed several significant alterations, including a pronounced reduction of miR-128 in tumor samples.

CNS germinomas: what is the best treatment strategy?

CNS germ cell tumors are rare primary brain malignancies. Germinomas comprise approximately two-thirds of CNS germ cell tumors. Owing to their radiosensitivity, radiotherapy has been used to treat patients with CNS germinomas, with favorable treatment outcomes.

Primary meningeal CNS lymphoma treated with intra-arterial chemotherapy and blood-brain barrier disruption.

Diffuse large B-cell lymphoma of the meninges is a particularly rare form of primary CNS lymphoma. We report a case of a 63-year-old woman found to have primary meningeal lymphoma (PML) with dural and leptomeningeal involvement whom we treated with multiple cycles of intra-arterial (IA) methotrexate, intravenous (IV) etoposide phosphate, and IV cyclophosphamide after reversible osmotic blood-brain barrier disruption (BBBD). Improvement was evident on gadolinium-enhanced brain MRI one month into therapy.

Lithium inhibits invasion of glioma cells; possible involvement of glycogen synthase kinase-3.

Therapies targeting glioma cells that diffusely infiltrate normal brain are highly sought after. Our aim was to identify novel approaches to this problem using glioma spheroid migration assays. Lithium, a currently approved drug for the treatment of bipolar illnesses, has not been previously examined in the context of glioma migration.

A phase II study of thalidomide and irinotecan for treatment of glioblastoma multiforme.

Purpose: Irinotecan is a cytotoxic agent with activity against gliomas. Thalidomide, an antiangiogenic agent, may play a role in the treatment of glioblastoma multiforme (GBM). To evaluate the combination of thalidomide and irinotecan, we conducted a phase II trial in adults with newly-diagnosed or recurrent GBM.

Glioblastoma multiforme.

Patients with newly diagnosed glioblastoma multiforme should undergo a maximal tumor resection and then, whenever possible, should be entered into a clinical trial. The current standard of care consists of external beam irradiation, to a total of 60 Gy over 6 weeks, in combination with low-dose daily temozolomide, followed by at least six cycles of adjuvant temozolomide. If radiotherapy and a temozolomide-based adjuvant regimen fail, the most active treatment approach appears to be bevacizumab and irinotecan.
