The purpose of this research study is to see if investigators can predict how brain functioning changes after radiation treatment based on PET scans and blood tests. Most participants experience at least mild decreases in their memory or attention after radiation therapy. Investigators hope that PET scans, lumbar puncture, and blood tests might help investigators predict who might have larger changes in their brain function after radiation.
High-grade glioma is the most common primary malignant tumor in central nervous system, and its high tumor heterogeneity is the main cause of tumor progression, treatment resistance and recurrence. Habitat imaging is a segmentation technique by dividing tumor regions to characterize tumor heterogeneity based on tumor pathology, blood perfusion, molecular characteristics and other tumor biological features. In some studies, the Hemodynamic Multiparametric Tissue Signature (HTS) method has been proven to be feasible. The Hemodynamic Multiparametric Tissue Signature (HTS) consists of a set of vascular habitats obtained by Dynamic Susceptibility Weighted Contrast Enhanced Magnetic Resonance Imaging (DSC-MRI) of high-grade gliomas using a multiparametric unsupervised analysis method. This allowed them to automatically draw 4 reproducible vascular habitats (High-angiogenic enhancing tumor; Low-angiogenic enhancing tumor; Potentially tumor infiltrated peripheral edema; Vasogenic peripheral edema) which enable to describe the tumor vascular heterogeneity robustly. In other studies, contrast-enhancing mass can divided into spatial habitats by K-means clustering of voxel-wise apparent diffusion coefficient (ADC) and cerebral blood volume (CBV) values to observe the changes of voxels in spatial habitat on the time line. Using this so-called spatiotemporal habitat to identify progression or pseudoprogression in cancer therapy. Above all, we have sufficient and firm reasons to deem that habitat imaging based on multiparametric MRI is more conducive to reflect the potential biological information inside the tumor and realize individualized diagnosis and treatment. To sum up, the assumption of this experiment is that the Habitats Created by preoperative or postoperative Multiparametric MRI ,such as conventional MRI sequences, Dynamic Susceptibility Weighted Contrast Enhanced Magnetic Resonance Imaging (DSC-MRI), Dynamic Contrast Enhanced Magnetic Resonance Imaging (DCE-MRI), Diffusion Weighted Magnetic Resonance Imaging(DWI) ,Vessel Size Imaging (VSI) ,or Magnetic Resonance Spectroscopy (MRS) can predict the molecular mutation status, prognosis, treatment residence, progression, pseudoprogression, and even recurrence and distant intracranial recurrence in patients with high-grade gliomas.
High-grade gliomas represent 60 to 70% of adult glial tumors and are highly aggressive with average survival from 12 to 15 months for glioblastomas (WHO grade IV gliomas) and from 2 to more than 5 years for WHO grade III gliomas. The treatment of initial stage high-grade gliomas is made with the most complete excision surgery possible followed by adjuvant radiochemotherapy or an exclusive radiochemotherapy if excision is impossible. Most often, these treatments are followed by adjuvant chemotherapy. Treatment of recurrence is most often re-irradiation according to stereotaxic modalities. Determination of the volumes to be irradiated conditions effectiveness and tolerance in the planning of these treatments. The definition of Gross Tumor Volume (GTV) is based on enhancing - T1 magnetic resonance imaging (MRI) after gadolinium injection. A margin of 1-2 mm is applied to define the PTV (Planning Target Volume) or irradiated volume, approximately equal to the GTV-MRI. Amino acid PET-CT (Positon Emission Tomography with Computed Tomography) could be an interesting alternative to tumor delineation because its results, do not depend on the rupture of the blood-brain barrier. Several studies have used amino acid PET in the planning of radiotherapy treatment for high-grade gliomas, but without a well-conducted prospective study. In the recurrent high-grade glioma population, no studies have been performed with 18F-DOPA.( 6-fluoro-[18F]-L-dihydroxyphenylalanine) The question therefore relates to the interest of cerebral 18F-DOPA PET-CT to improve the delineation of the volumes to be re-irradiated, during the recurrence of high-grade gliomas, and on the optimal methodology for determining GTV- PET. To compare GTV-TEP and GTV-MRI volumes with each other, and the r-GTV, volume corresponding to the relapse objectified on the follow-up MRI, the analysis will be based on 3 parameters: - DICE index, similarity index between 2 volumes, - Contoured Common Volume (VCC), intersection of 2 volumes between them, - Additional Contoured Volume (VSC), total volume delineated with imaging minus the common volume between 2 imageries. Thus, within the rGTV relapse volume, it's important to know whether VSC of 18F-DOPA PET-CT is significant compared to that of MRI and would thus allow better definition of the volumes to be irradiated.
G-SUMIT is a pilot, phase II,randomized controlled trial to evaluate the feasibility of performing a large-scale trial in patients undergoing surgery for first-time diagnosis of high grade glioma (HGG) in a surgically favorable anatomical location to answer the following: Does extending the margin of resection 1 cm beyond visible enhanced volume on MRI result in (a) an increase in overall survival? (b) result in a similar rate of "clinically-significant" neurological worsening during 30 days post surgery and quality of life at 6 and 12 months?
The objective of this clinical investigation is to assess the safety and performance of the SonoClear Acoustic Coupling Fluid (ACF). The performance will be assessed by analysis of the contrast-to-noise ratio (CNR) and assessment of image quality by using the Surgeon Image Rating (SIR) Scale. This is a prospective, multi-centre single-arm study where the performance of SonoClear ACF relative to routinely used acoustic coupling fluid is investigated by each patient being their own control. Patients with the diagnosis of HGG and LGG at up to 10 sites will be included. Additionally, safety data are collected at 30 days and 6 months post-procedure.
This is a pilot study that will evaluate disease status in children that have been newly diagnosed high-grade glioma with TRK fusion. The evaluation will occur after 2 cycles of the medication (Larotrectinib) have been given. The study will also evaluate the safety of larotrectinib when given with chemotherapy in your children; as well as the safety larotrectinib when given post-focal radiation therapy.
A Phase 0 single center, first in human, open-label study of ascending energy doses of sonodynamic therapy (SDT) utilizing the MRgFUS combined with intravenous ALA to assess safety and efficacy in up to 45 participants with recurrent HGG. Eligible participants who are scheduled for resection will be administered intravenous (IV) aminolevulinic acid HCl (ALA) approximately six to seven (6-7) hours prior to receiving sonodynamic therapy (SDT).
The primary objective of this trial is to evaluate the seizure frequency during a course of radiotherapy for high-grade (grade III or IV) gliomas. The patients keep a seizure diary during and up to 6 weeks following radiotherapy. Every day, the patients document the number (and type) of seizures and intake of anti-epileptic medication. At the end of radiotherapy, the patients are asked to complete a questionnaire regarding their satisfaction with the seizure diary. Progression of seizure activity compared to baseline is defined as increase of frequency of seizures by more than 50%, increase of severity of seizures, or as Initiation or increase anti-epileptic medication by at least 25%. To obtain an objective assessment of seizure activity in addition to patient reported outcomes, an electroencephalography (EEG) is performed during the first and the sixth week of radiotherapy, and during the sixth week following radiotherapy. The main goal of the study is to generate objective data regarding the occurrence, frequency and severity of seizures as well as regarding the use of anti-epileptic medication during the course of radiotherapy for high-grade gliomas. These data are used to evaluate the potential effect of radiotherapy on occurrence of seizures in these patients and generate hypotheses. Therefore, statistical analyses of primary and secondary endpoints focus on descriptive methods. If statistical tests are applied, they are to be interpreted from an exploratory perspective. Thirty-two patients with documented start of radiotherapy and any documented diary data at baseline and after start of radiotherapy should be subjected to statistical analysis. Assuming that 10% of patients do not fulfil these requirements, a total of 35 patients should be enrolled to this trial. Recruitment should be completed within 12 months. With this sample size a one-sample binomial test with a one-sided significance level of 2.5% has a power of 80% to yield statistical significance if the rate of patients with progression of seizure events during the course of radiotherapy compared to baseline is 30% (rate under the alternative hypothesis) assuming a 'natural' background progression-rate of 10% without radiotherapy (null hypothesis). If the natural course of the disease would lead to a progression-rate of 5% without radiotherapy only, the power increases to 98%.
