Filter by:In the preoperative waiting area, the patients are randomly assigned and divided into two groups according to the allocation sequence table (corresponding to 1:1 randomization) generated by the computer. The propofol group was both induced and maintained at an effect-site concentration (Ce) of 2.0-4.0 mcg/mL by a target-controlled infusion (TCI) system. The sevoflurane group was maintained via sevoflurane vaporizer between 1% and 3% (target minimum alveolar concentration of 0.7-1.3). The following patient data were recorded, the type of anesthesia, sex, age at the time of surgery, preoperative Karnofsky performance status (KPS) score and functional capacity, the postoperative complications within 30 days (according Clavien-Dindo classification), American Society of Anesthesiologists(ASA) physical status scores, tumor size, intraoperative blood loss/transfusion, duration of surgery, duration of anesthesia, total opioid (remifentanil/fentanyl/ propofol) use, postoperative radiation therapy, postoperative chemotherapy, postoperative concurrent chemoradiotherapy, the presence of disease progression, and 6-month, 1-year, and 3-year overall survival and Karnofsky performance status score were recorded.
QARIN 1 is a study of [18F]DPA-714 Translocation Protein (TSPO) Positron Emission Tomography (PET) for longitudinal, quantitative assessment of brain neuroinflammation following whole brain radiation therapy. This TSPO PET, uses a radioactive tracer. An optional MRI (magnetic resonance imaging) will also be performed to monitor brain microstructure damages induced by neuroinflammation. Primary Objectives - Assessment of temporal and regional variability of uptake of translocator protein (TSPO) positron emission tomography (PET) tracer. - Regional variability will be assessed in medial temporal lobe, frontal lobe, and in white matter - Temporal variability will be assessed by scanning each subject four-times: at baseline (before or within 2 weeks of start of radiation therapy), before start of chemotherapy, at 1 year from the initiation of the radiation therapy, and at 1.5-2 years from the initiation of the radiation therapy - Correlation of radiation dose in specific brain regions with radiation induced neuroinflammation as measured by uptake of TSPO PET tracer. Exploratory Objectives - Assessment of radiation-induced brain microstructure injuries (RIBMI) in specific brain regions (medial temporal lobe, frontal lobe, and in white matter) using advanced magnetic resonance imaging (MRI) techniques. - Association of radiation dose with MRI measures of RIBMI in these specific brain regions. - Association of PET measures of RIN with MRI measures of RIBMI. - Association of PET measure of RIN and MRI measures of RIBMI in specific regions of interest (ROI) with specific domain of neuro-cognition. For example, to investigate whether PET measure of RIN and MRI measures of RIBMI in hippocampal ROI have strongest association with episodic memory; whether frontal lobe cortical ROI are associated with attention and executive function. - Association of a novel MRI based technique for assessment of RIN with TSPO PET. - Association of the PET and MRI measure of neuroinflammation within 2- years of completion of radiation with delayed cognitive outcome that will be measured at 3, 4 and 5 years from the completion of radiation
This is a single center, multi-arm, biomarker-driven phase 1 study to assess the RP2D, PK/PD, safety, and activity of tepotinib in participants with MET alterations and brain tumors. Eligible patients include those with brain metastases or glioblastoma, including patients who are surgical candidates. In patients with EGFR+ NSCLC with EGFR-TKI resistance and MET amplification, tepotinib will be given in combination with osimertinib. This phase 1 study will be conducted in 2 parts, Phase 1a (dose exploration) and Phase 1b (dose expansion). Phase 1a will include a surgical resection window of opportunity component. Phase 1b (dose expansion) can open once the relevant RP2D has been estimated in Phase 1a (dose exploration). Phase 1a (Dose Exploration): Patients will be assigned to dose levels within a Group as outlined in the Statistical Analysis Plan. Group A will be comprised of patients who are surgical resection candidates with newly-diagnosed or recurrent brain metastases and MET alteration. Group B will be comprised of patients who are surgical resection candidates with recurrent glioblastoma and MET alteration. Group C will be comprised of patients with newly-diagnosed or recurrent brain metastases and epidermal growth factor receptor mutated (EGFR+) non-small cell lung cancer (NSCLC). Phase 1b (Dose Expansion): Upon completion of the Phase 1a (dose exploration) component and estimation of a RP2D, dose expansion may proceed within Group A (consisting of patients with brain metastasis and MET alteration) and Group C (EGFR+ NSCLC brain metastasis, TKI resistance, and MET amplification). Dose expansion in these 2 groups may be done concurrently, but enrollment in each group does not require completion of the entire Phase 1a component of the study. There will not be a Group B (glioblastoma) in Phase 1b. Patients in Phase 1b will not undergo surgical resection.
There are currently no visual rehabilitation strategies for children presenting visual field defects consecutive to a brain tumor or its treatment. This study seeks to investigate the use of a home-based stimulation visual rehabilitation program using immerse-virtual reality (IVR) in children aged 4-10 years old with a diagnosis of hemianopia
Predicting the survival of patients diagnosed with glioblastoma (GBM) is essential to guide surgical strategy and subsequent adjuvant therapies. Intraoperative ultrasound (ioUS) is a low-cost, versatile technique available in most neurosurgical departments. The images from ioUS contain biological information possibly correlated to the tumor's behavior, aggressiveness, and oncological outcomes. Today's advanced image processing techniques require a large amount of data. Therefore, the investigators propose creating an international database aimed to share intraoperative ultrasound images of brain tumors. The acquired data must be processed to extract radiomic or texture characteristics from ioUS images. The rationale is that ultrasound images contain much more information than the human eye can process. Our main objective is to find a relationship between these imaging characteristics and overall survival (OS) in GBM. The predictive models elaborated from this imaging technique will complement those already based on other sources such as magnetic resonance imaging (MRI), genetic and molecular analysis, etc. Predicting survival using an intraoperative imaging technique affordable for most hospitals would greatly benefit the patients' management.
Prospective observational study on patients undergoing decompressive craniotomy
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.
Primary Objectives To investigate the relationship between dynamic MRI, brain tumor perfusion (DSC) and permeability (DCE), and dynamic 18F-FAZA PET uptake. Secondary Objectives To investigate the relationship between tumors with greater hypoxia defined by qBOLD and 18F-FAZA PET and pathological features including proportionate necrosis, Ki-67 and IDH mutation status To investigate the correlation between the hypoxic tumor region delineated using 18F-FAZA PET and qBOLD
There is limited knowledge regarding the quality of life and needs of patients with advanced high grade gliomas, especially during the end of life. By doing this research, we are able to assess caregiver and patient symptoms and needs during the end of life phase of patients with brain tumors.
The purpose of this study is to determine whether the study medication, brivaracetam, is tolerable and safe for patients with brain tumors.
