Filter by:Levetiracetam is the commonly preferred anti-seizure medicine in patients with brain tumors. This drug has reduced the risk of seizure events occurring but is associated with a risk of side effects such as increased headache, drowsiness, loss of muscle coordination, and psychological challenges in patients. In patients undergoing appropriate treatment for brain tumors and controlled of seizures in the initial few months of levetiracetam, the chance of further seizures is relatively low. The optimal duration to give levetiracetam is not well defined for these patients, and currently as standard treatment levetiracetam is continued for 2-3 years. This study aims to answer this question by comparing patients on a short course of levetiracetam (experimental arm) versus a longer course of levetiracetam (standard arm), with the anticipation that a shorter duration of treatment will not lead to increased seizure episodes.
This Phase 2 trial will assess the safety, tolerability, efficacy, imaging pharmacodynamics, and pharmacokinetics of RVP-001, a novel manganese-based MRI contrast agent, at three escalating dose levels. RVP-001 will be administered as a single IV bolus to subjects with known gadolinium-enhancing central nervous system (CNS) lesions (for example stable brain tumor or multiple sclerosis) who have recently had a gadolinium-based contrast agent (GBCA)-enhanced MRI of the brain.
Effect of sugammadex for reversal of rocuronium-induced neuromuscular block on Perioperative Management of awake Craniotomy
Primary and secondary brain tumors are a constant challenge for the medicine. Tissue sensitivity to ionizing radiation differs and depends on numerous factors and the same dose of radiation may produce different effects in particular structures of the CNS. It can also affect the surrounding healthy tissues and lead to adverse effects like the cognitive or physical function impairment. One of brain structures most sensitive to ionizing radiation is the limbic system, especially the hippocampus, because it is here that the postnatal neurogenesis takes place via neural stem cells, which are a self-renewing population of precursor cells. There have been no studies that would thoroughly examine the impact of different CNS radiation therapy techniques on the cognitive function, potential neuroplasticity markers or blood-brain barrier damage in brain tumor patients with a concomitant use of neurocognitive combination therapies or physical exercise, and their impact on the CNS function. The aim of the study is to assess the impact of selected RT techniques: IMRT, WBRT, and CyberKnife (SRS) on the processes regulating cognitive and physical function in patients with primary (Group III and IV, WHO, 2016) and metastatic CNS tumors. The secondary objective is the analysis of the effect of selected forms of neurorehabilitation on the parameters studied. The study will be a prospective clinical trial conducted in 150 patients. Patient evaluation will be carried out before RT, after RT, during a follow-up visit-3 months after RT, and finally after 6 months. The methods will be used: analysis of the blood-brain barrier permeability markers including exact connection proteins, markers confirming neuroplasticity of the brain, cerebral secretory activity, and onco- and anti-neuronal antibody activity, brain structure analysis (MRI) and volume testing of selected brain structures, and assessment of cognitive and physical function of the patients. The study will be a part of the search trend aiming to explain the mechanism of the formation of cognitive-behavioral disorders in humans based on the most fundamental principles governing information processing in CNS, and the impact of neoplasia and ionizing radiation on selected brain structures and functions. The results of the study might become a starting point for the formulation of new guidelines on the level of physical activity or cognitive exercise in patients treated with CNS radiation therapy.
This is a study of amifostine to determine how effective it is in the reduction of infection in a high dose chemotherapy regimen with autologous stem cell rescue in children with high risk, relapsed or refractory pediatric solid tumors.
Background. Survivors of childhood brain tumours have the poorest health-related quality of life of all cancer survivors due to the multiple physical and psychological sequelae of brain tumours and their treatment. Remotely delivered Acceptance and Commitment Therapy (ACT) may be a suitable and accessible psychological intervention to support young people who have survived brain tumours. Aims. This study aims to assess the feasibility and acceptability of remotely delivered ACT to improve quality of life among young brain tumour survivors. Method. This study is a two-arm, parallel group, randomised controlled trial comparing ACT with waitlist control. Participants will be aged 11-24 years and survivors of brain tumours who have completed cancer treatment. Participants will be randomised to receive 12 weeks of ACT either immediately or after a 12-week wait. The durability of treatment effects will be assessed by further follow-up assessments at 24-, 36- and 48- weeks. The DNA-v model of ACT will be employed, which is a developmentally appropriate model for young people. Feasibility will be assessed using the proportion of those showing interest who consent to the trial and complete the intervention. A range of clinical outcome measures will also assess physical and mental health, everyday functioning, quality of life and service usage. Acceptability will be assessed using participant evaluations of the intervention, alongside qualitative interviews and treatment diaries analysed thematically. Discussion. This study will provide an initial assessment of the value of remotely delivered ACT in supporting recovery and coping for young people after brain tumour treatment.
An optimal analgesic therapy is very important for postoperative recovery. In recent years, several studies showed that the prevalence of the moderate to severe pain after craniotomy ranged from 69 to 87% of patients. The investigators showed that the use of morphine based patient controlled analgesia prevented moderate to severe postoperative pain in patients undergoing supratentorial craniotomy. Morphine related side effects such as sedation, miosis, respiratory depression, nausea and vomiting produce a general reluctance for their use in neurosurgery. Therefore, all patients were closely observed to detect opioid related side effects in the intensive care unit for 24 hours following surgery in our previous study. The Integrated Pulmonary Index (IPI) is a new tool that calculates respiratory and hemodynamic parameters noninvasively. In the present study the investigators will use different doses of morphine based patient-controlled analgesia and the IPI system to determine more effective and safer morphine dose for postoperative analgesia following supratentorial craniotomy.
During a brain surgery targeted to remove a brain tumor, the neurosurgeon wakes up the patient to delimit the tumor area exactly, and identify the surrounding areas, to limit the surgery damages. The present project aims at testing the patient in this awake phase to determine the brain areas implied in time to contact (TTC) perception, a function that allows determining the arrival time of moving objects and used in many tasks of our daily life.
MIRNA is a prospective multi-center observational study designed to explore 762 plasma microRNAs in patients with malignant CNS tumours: 60 primary glioblastoma (GBM), 20 primary CNS lymphomas and 40 brain metastases in an attempt to establish plasma microRNA signatures specific to GBM capable of distinguishing them from malignant non-glial brain tumours. 20 patients with cerebral stroke and 20 healthy volunteers will also participate in the study, and for each patient, a panel of 762 microRNAs will be screened in plasma.
The purpose of this study is to evaluate the effect of the ketogenic diet on tumor size and quality of life in pediatric patients with malignant or recurrent/refractory brain tumors.
