Filter by:Perioperative pain management for craniotomy patients may be challenging because the commonly used agents such as opioids, gabapentin, and dexmedetomidine also cause sedation, which can confound the neurological exam and can lead to respiratory depression and increased intracranial pressure. Preoperative intravenous magnesium boluses and infusions have previously been established as an effective, nonsedating analgesic that can reduce opioid consumption 25-30% up to 48 hours postoperatively. However, intravenous magnesium has not seen widespread use in craniotomy patients due to concerns for interference with the neurological monitoring that commonly occurs in these cases. Intravenous magnesium given as a bolus preoperatively or as a constant infusion may avoid these problems and has never been investigated. The goal of this study is to compare intravenous magnesium given preoperatively and intraoperatively to placebo in adult elective craniotomy patients to improve quality of recovery postoperatively, and evaluate safety and tolerability. Secondary endpoints will include evaluating for pain, sedation, agitation, blood pressure, and opioid consumption postoperatively.
This is a retrospective, mono centric, exploratory study to assess the incidence of a genomic alteration: NTRK gene fusion, in adult gliomas and brain metastases.
This is a research study to find out if the new anti-cancer drug Durvalumab combined with radiation therapy to the brain will work in treating brain metastases from non-small cell lung cancer (NSCLC). Focused, highly precise radiation therapy to the brain, known as stereotactic radiosurgery (SRS), is a standard of care treatment that is commonly used for patients with metastatic lung cancer to the brain. It is standardly used as an alternative to surgery to eradicate the targeted tumours in the brain and prevent them from growing and causing symptoms. This study will look at the combination of the novel immunotherapy Durvalumab with two different ways of delivering SRS: 1) with each radiation treatment given every other day for 3 treatments with the first dose of Durvalumab (fSRT), or 2) with each radiation treatment, referred to as a "pulse," given every 4 weeks with each dose of Durvalumab for 3 treatments (PULSAR).
This is a prospective, randomized, 2-arm, Phrase 2, superiority and multicenter study to compare the efficiency of Anti-HER2 TKI versus Pertuzumab in Combination With Dose-dense Trastuzumab and Taxane in HER2-positive breast cancer patients with active refractory brain metastases.
This study uses a cranial implant to deliver cortical stimulation that, when paired with physiotherapy, will remap the brain so that critical brain functions can be protected during brain tumor surgery. This pilot study will provide initial evidence for the safety and feasibility of such a protocol which will lead to future pivotal trials that could radically change eloquent area brain surgery. For patients with otherwise incompletely resectable brain tumors, this could mean a longer life expectancy and a better quality of life.
Almonertinib is a three-generation epidermal growth factor receptor tyrosine kinase inhibitor(EGFR-TKI), which has shown competitive potential in the second-line treatment against first-generation TKIs. This study intends to assess the efficacy and safety of stereotactic radiosurgery with sequential almonertinib in treatment-naive EGFR-mutant NSCLC patients with brain metastases.
After stereotactic radiosurgery (SRS) of brain metastases, patients undergo a standard brain magnetic resonance imaging (MRI) to assess treatment response 12 weeks after completion of treatment. The interpretation of this standard MRI can sometimes be challenging as it can be difficult to differentiate tumour getting bigger/returning (progression/recurrence) from expected radiotherapy treatment-related changes known as radionecrosis. This study is a pilot brain imaging study that is investigating if readily available forms of imaging such as contrast-clearance analysis MRI (also known as TRAMs) and/or 18 Fluoromethyl-choline positron emission tomography/computerised tomography (18F-choline PET/CT) are equivalent to multi-parametric MRI in their ability to differentiate tumour from radionecrosis. Multi-parametric MRI has the most evidence for its ability to discriminate tumour from radionecrosis but is resource intensive and not routinely available in most centres.
This is a multi-center, single-arm, open-label, Phase 2 clinical study of Dacomitinib for EGFR Mutated Non-Small Cell Lung Cancer (NSCLC) With Brain Metastases.
Hyperosmotic agents are used to decrease intracranial pressure. The aim of the study is to compare the effects of continuous 3% hypertonic saline (HS), bolus HS and 20% mannitol on intraoperative brain relaxation in patients with raised intracranial pressure during surgery for supratentorial tumors.
Brain metastasis is the most common neurological complication in tumor patients, and lung cancer is the most common tumor with brain metastasis. The prognosis of patients with non-small cell lung cancer with brain metastasis is poor. If not treated, the median survival time was about 1 month, the median survival time for steroid therapy was about 2 to 3 months, and the median survival time for patients receiving whole brain radiotherapy was about 3 to 6 months. Studies have shown that the incidence of brain metastasis is not only related to tumor size, N stage and tumor cell type, but also more likely to occur in NSCLC patients with sensitive gene mutation. With the rapid development of NSCLC molecular targeted therapy and precise radiotherapy, the new main therapeutic methods for NSCLC brain metastasis in recent years include stereotactic radiotherapy for (SRT),. Based on intensity modulated technique, simultaneous modulated accelerated radiation therapy for Brain(SMART-Brain) and molecular targeted therapy were carried out. However, at present, the best treatment choice for NSCLC brain metastasis, especially for asymptomatic brain metastasis patients, is still controversial. The choice and combined application mode of individualized treatment for different patients is still a problem to be explored. Based on the synergistic effect of radiotherapy and molecular targeted therapy on the basis of cell and molecule, The purpose of this study was to prospectively compare the efficacy of radiotherapy combined with targeted therapy and targeted therapy alone in patients with asymptomatic NSCLC brain metastasis with gene sensitive mutations, and subgroup analysis of different molecular targets and mutation sites. It is expected that this study will provide a basis for optimizing the curative effect of patients with NSCLC brain metastasis.
