Filter by:The blood-brain barrier (BBB) is a specialized interface allowing a unique environment for neuro-glia networks. BBB dysfunction is common in brain disorders. The Transcranial Magnetic Stimulation (TMS) is a non-invasive method of stimulating cortical motor neurons with the use of rapidly changing electromagnetic fields generated by a coil placed over the scalp. The objective of this study is to evaluate the safety and effects of the deep TMS (dTMS) on barrier integrity in patients with malignant glial tumors. BBB permeability will be quantified using dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI). Permeability change will be compared between two DCE-MRI scans performed immediately after "real" and "sham" rTMS, randomly assigned within one week of each other.
The aim is to classify high grade glioma by matrix-assisted laser desorption/ionization mass spectrometry imaging (MALDI MSI). In order to provide more specific informations for the diagnosis and the prognosis of high grade glioma.
Glioblastoma multiforme (GBM) is the most common primary malignant brain neoplasm in adults. Despite recent diagnostic and therapeutic advances, including aggressive surgical resection and chemoradiation, the prognosis of GBM has improved only slightly over the past two decades, with median survival of approximately 15 months. Tumor hypoxia is a feature of GBM that contributes to poor outcome through multiple mechanisms such as 1) overexpression of enzymes that play roles in temozolomide resistance, the main chemotherapeutic agent in GBM and 2) increase expression of cancer stem cells which are more resistant to radiation. Hypoxic tumour regions are associated with higher rates of progression and recurrence. In this study the investigators will use an advanced MRI technique called qBOLD to non-invasively measure oxygenation in GBM and obtain targeted biopsies. The investigators take advantage of physical characteristics of Ferumoxytol (Feraheme®) which is an iron supplement, and utilize two recent technical advances not previously used in human tumours to quantitatively measure oxygenation in GBM. Prior knowledge of hypoxia can assist in prognostication and individualization of treatment planning with special focus on hypoxic regions by targeted radiation dose or regimen modulation; consideration of more intensive chemotherapy regimens; more aggressive and targeted surgical resection and closer short-term clinical and imaging follow-ups.
This is Proof-of-Concept (POC) study to assess the preliminary antitumor activity and safety and tolerablity using ceritinib (LDK378) in the treatment of life threatening tumors that are characterized by ALK genetic alteration (and/or overexpression in some diseases).
The purpose of this research study is to determine if an investigational dendritic cell vaccine, called pp65 DC, is effective for the treatment of a specific type of brain tumor called glioblastoma (GBM) when given with stronger doses of routine chemotherapy.
Glioblastoma (GBM) accounts for approximately 50% of all glioma and among these tumors, are the most malignant. The cells of origin of glioma are still undefined, but the most putative target cells include astrocytes, neural stem cells, and oligodendrocyte precursor cells. The current standard of care for patients with newly diagnosed GBM includes temozolomide and radiotherapy . Melanocortins are peptides with well-recognized anti-inflammatory and neuroprotective activity. Of the five known melanocortin receptors (MCRs), only subtype 4 is present in astrocytes and it is expressed predominantly in the brain. No data are currently available on MC4R gene polymorphisms and gliomas or their relationship with radiotherapy or chemotherapy. Aim. Given the association of MC4R with antiinflammatory activity, neuroprotection, induction of neural stem/progenitor cell proliferation in brain hypoxia, and prevention of astrocyte apoptosis, the aim of this study is to retrospectively evaluate the possible prognostic/predictive role of the MC4R SNPs on GBM therapy.
This study is a clinical trial to determine the safety of injecting G207 (a new experimental virus therapy) into a recurrent or progressive brain tumor. The safety of combining G207 with a single low dose of radiation, designed to enhance virus replication and tumor cell killing, will also be tested.
This phase II trial studies the side effects and how well vaccine therapy works when given together with temozolomide in treating patients with newly diagnosed glioblastoma. Vaccines made from the survivin peptide or antigen may help the body build an effective immune response to kill tumor cells that express survivin. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether temozolomide is more effective with or without vaccine therapy in treating glioblastoma.
This phase I trial studies the side effects and the best dose of wild-type reovirus (viral therapy) when given with sargramostim in treating younger patients with high grade brain tumors that have come back or that have not responded to standard therapy. A virus, called wild-type reovirus, which has been changed in a certain way, may be able to kill tumor cells without damaging normal cells. Sargramostim may increase the production of blood cells and may promote the tumor cell killing effects of wild-type reovirus. Giving wild-type reovirus together with sargramostim may kill more tumor cells.
Primary tumor glioblastoma is the most common malignant brain. Standard treatment includes biopsy or excision of the tumor in order to obtain a pathological diagnosis, and tumor mass reduction. After the surgery patients are treated with radiation and Temodal. The most common psychiatric symptom in this patient population is depression, valued at up to approximately 50% in patients with glioma . Depression not only adversely affects the quality of life of patients but also impairs the ability and cognitive function due to the complex clinical course of patients with glioblastoma. There is a tendency to give Diagnosis of depression in this patient population, due to a lack of awareness, knowledge and literature on the subject. This study was designed to prospectively randomized, controlled, double-blind study. This method of recruitment - patients who undergo resection or biopsy of glioblastoma (newly diagnosed glioblastoma), immediately after diagnosis, patients will receive an explanation about the study and sign a consent form will enter research.
