Filter by:The association between the presence of pruritus, especially centrofacial, and the presence of a brain tumor is a widespread notion in the medical community but based on a single publication by Andreev et al. in the British Journal of Dermatology published in 1975. No other study has studied this association with a rigorous methodology. The aim of this study is to evaluate the prevalence of pruritus in patients with one or more primary or secondary brain tumor(s), benign(s) or malignant(s).
This research study is studying a novel drug called ALRN-6924 as a possible treatment for resistant (refractory) solid tumor, brain tumor, lymphoma or leukemia. The drugs involved in this study are: - ALRN-6924 - Cytarabine (for patients with leukemia only)
This Phase I dose-escalation trial is designed to determine the safety and feasibility of rapidly generated tumor multi-antigen associated specific cytotoxic T lymphocytes (TAA-T) in patients with newly diagnosed diffuse intrinsic pontine gliomas DIPGs (Group A) or recurrent, progressive, or refractory non-brainstem CNS malignancies (Group B). Pediatric and adult patients who have high-risk CNS tumors known to typically have positivity for one or more Tumor Antigen Associated (TAA) (WT1, PRAME and/or Survivin) will be eligible. TAA-T will all be generated from patient peripheral blood mononuclear cells (PBMC). Group A patients (DIPG): The first TAA-T dose will be infused any time 14 days or more after completion of radiotherapy. Group B patients (other recurrent/progressive/refractory CNS tumors): The first TAA-T dose will be infused any time 14 days or more after completing most recent course of conventional (non-investigational) therapy for their disease AND after appropriate washout periods as detailed in eligibility criteria.
This study is to evaluate the safety and find the tolerated ultrasound dose of transient opening of the blood-brain barrier (BBB) by using the NaviFUS System in recurrent GBM patients.
The purpose of this study is to test the accuracy of using an imaging technique called breath-holding functional magnetic resonance imaging (BH fMRI) in addition to the standard imaging test described above. This study will allow the researchers to find out whether using BH fMRI in combination with the standard approach is the same as, better, or worse than the standard approach used alone.
Readmissions increasingly serve as a metric of hospital performance, inviting quality improvement initiatives in both medicine and surgery. Recently, a readmission reduction program in the United States was associated with significantly shorter length of stay, earlier discharge, and reduced 30-day readmission after elective neurosurgery. These results underscore the importance of patient education and surveillance after hospital discharge, and it would be beneficial to test whether the same approach yields beneficial results in a different health system, the NHS. In this study, the investigators will replicate the Transitional Care Program (TCP) published by Robertson et al.(Journal of Neurosurgery 2017) with the goal of decreasing length of stay, improving discharge efficiency, and reducing readmissions in neurosurgical patients by optimizing patient education and post-discharge surveillance.
In neurosurgery, brain tumor patients show increased levels of lactate at the beginning of surgery. This has been related to malignancy. Ki-67 is a cell proliferation index used as a marker of tumor mitotic activity. This research aims to describe the correlation between lactate levels and the Ki-67 index in patients with brain tumor.
Glioblastoma is the most frequent and aggressive primary brain tumor in adults. A team recently showed that baseline plasma levels of matrix metalloproteinase-2 (MMP2) and matrix metalloproteinase-9 (MMP9) were correlated to bevacizumab activity in patients with recurrent glioblastoma. To date, the biological rationale of this results remains unknown but MMP2 could be involved in classical angiogenesis while MMP9 could promote vasculogenesis. The objectives are to correlate the plasma levels of MMP2 and MMP9 to their Ribonucleic acid (RNA) and protein tissue expression, activity and to patient neuro-imaging features. To analyze the changes of MMP2 and MMP9 plasma levels during peri-operative period and after radio-chemotherapy. Methods: Plasmatic levels of MMP2, MMP9, vascular endothelial growth factor-A (VEGFA), vascular endothelial growth factor-R2 (VEGFR2), stromal cell-derived factor 1 (SDF1) and chemokine receptor-4 (CXCR4) will be analyzed by enzyme-linked immunosorbent assay (ELISA) in pre-, post-operative period, before radiotherapy, before adjuvant temozolomide and at relapse in newly diagnosed glioblastoma. RNA expression of these factors will be analyzed by reverse transcription-Polymerase chain reaction (RT-qPCR) on frozen tumor samples, whereas protein expression will be analyzed by ELISA and immunohistochemistry. Enzymatic activity of MMP2 and MMP9 will be analyzed by zymography. Tumor volume, infiltration and perfusion degrees will be analyzed on Magnetic Resonance Imaging (MRI) performed before and after surgery and before adjuvant temozolomide. Neuro-imaging characteristics will be correlated to plasma and tissue expressions of these factors. The expected results are to better define the expression profile of MMP2, MMP9 and the change in their plasma level during treatment, a prerequisite for their clinical use.
This study will thus examine daily behaviour based on smartphone use and link it to the neurological and neuropsychological status as well as to neuroradiological studies that are part of the clinical routine. The study will examine behaviour changes before and after surgery, and how this change in measured behaviour with the smartphone relates to today's "gold standard", namely professional neuropsychological examination and quantification of brain damage on imaging studies (MRI). This study is a proof-of-principle study that intends to build the basis for larger future observational studies on patients with focal or diffuse brain pathologies.
This protocol is designed to assess the need for seizure prophylaxis in the perioperative period for patients undergoing neurosurgical procedure (gross-total resection, sub-total resection or biopsy) for suspected diagnosis of new, recurrent or transformed glioma (WHO grade I-IV) and brain metastasis. This will be determined by observing the impact of Lacosamide (LCM), Levetiracetam (LEV), or no anti-epileptic drug (AED) on whether visits to the emergency department (ED) or hospital re-admissions occur within 30 days after procedure. A secondary endpoint will evaluate the safety and tolerability of LCM and LEV. Exploratory endpoints will evaluate admission duration for the procedure, number of post-operative provider communications (telephone, email, and additional clinic encounters, etc.), and patient risk factors associated with post-operative seizure.
