The overall aim of this project is to improve the outcome of patients diagnosed with ependymoma by improving and harmonising the staging and the standard of care of this patient population and to improve the investigators understanding of the underlying biology thereby informing future treatment. The program will evaluate new strategies for diagnosis (centralized reviews of pathology and imaging) and new therapeutic strategies in order to develop treatment recommendations. Patients will be stratified into different treatment subgroups according to their age, the tumour location and the outcome of the initial surgery. Each subgroup will be studied in a specific randomised...
This clinical trial examines an investigational scan (64Cu-DOTA-trastuzumab positron emission tomography [PET]/magnetic resonance imaging [MRI]) in imaging patients with HER2+ breast cancer that has spread to the brain (brain metastasis). Diagnostic procedures, such as 64Cu-DOTA-trastuzumab PET/MRI, may help find HER2+ breast cancer that has spread to the brain and determine whether cancer in the brain takes up trastuzumab, which may predict for response to trastuzumab deruxtecan (the standard of care chemotherapy).
This clinical trial evaluates whether gallium-68 (Ga-68) prostate specific membrane antigen (PSMA)-11 positron emission tomography (PET)/computed tomography (CT) imaging is useful in differentiating between disease that has come back after a period of improvement (recurrence) or that is growing, spreading, or getting worse (progression) and treatment effect in patients with glioma. Patients with glioma undergo frequent imaging for assessment of disease status. After first-line treatment however, the correlation between imaging findings and tumor activity can be confused, and surgery is often required for definitive diagnosis. The PET/CT scanner is an imaging machine that combines...
The study is designed to use infusion of a non-radioactive, naturally occurring isotope of glucose (13C) in patients undergoing surgical resection for a newly identified brain mass to obtain the metabolic phenotype of the tumor, and correlate it with the histopathological diagnosis. In each patient, 13C NMR spectral analysis of tumor extracts will be obtained after intraoperative infusion of [U-13C]glucose or [1,2-13C]glucose. Whenever feasible, patients will undergo 3 preoperative imaging studies - 18FDG-PET, diffusion tensor imaging with 1H-spectroscopy on 3T MR scanner, and ultra high resolution MR imaging on the 7T MR scanner. The results of these imaging studies will be...
There is a variety of tumors affecting the pituitary gland in childhood; some of these tumors (eg craniopharyngioma) are included among the most common central nervous system tumors in childhood. The gene(s) involved in the pathogenesis of these tumors are largely not known; their possible association with other developmental defects or inheritance pattern(s) has not been investigated. The present study serves as a (i) screening/training, and, (ii) a research protocol. As a screening and training study, this protocol allows our Institute to admit children with tumors of the hypothalamic-pituitary unit to the pediatric endocrine clinics and wards of the NIH Clinical Center for...
EGFR mutation positive advanced NSCLC patients with CNS metastases were associated with poor prognosis. Furmonertinib showed promising CNS efficacy in doses of 80 mg orally once daily or higher in patients with EGFR T790M mutation positive NSCLC. This study aims to investigate the efficacy and safety of furmonertinib in the treatment of EGFR-sensitive mutation positive NSCLC patients with brain metastasis.
The study is being conducted to evaluate the efficacy, and safety of Lutetium (177Lu) Oxodotreotide Injection in Subjects With advanced gastrointestinal pancreatic neuroendocrine tumors.
This is a prospective, open, single-center study evaluating the efficacy and safety of surufatinib Combined With Temozolomide and S-1 as the first-line treatment of advanced neuroendocrine tumors
The main question it aims to answer are: 1. whether the new target delineation scheme can improve Progression-free Survival 2. whether it can reduce the incidence of radiation complications in high-grade glioma patients. Participants in trial group will be performed radiotherapy of new target delineation method after the completion of the operation within 4-6 weeks., while participants in the control group be performed radiotherapy of EORTC(European organisation for research and treatment of cancer) target delineation method.Temozolomide 75 mg / ( m² · d ) will be given to both groups of patients during radiotherapy. After radiotherapy, its dose changes to 150 ~...
Patients with relapsed medulloblastoma, ependymoma and ATRT have a very poor prognosis whether treated with conventional chemotherapy, high-dose chemotherapy with stem cell rescue, irradiation or combinations of these modalities. Antiangiogenetic therapy has emerged as new treatment option in solid malignancies. The frequent, metronomic schedule targets both proliferating tumor cells and endothelial cells, and minimizes toxicity. In this study the investigators will evaluate the use of biweekly intravenous bevacizumab in combination with five oral drugs (thalidomide, celecoxib, fenofibrate, and alternating cycles of daily low-dose oral etoposide and cyclophosphamide), augmented...
