Filter by:This phase II trial studies how well whole brain radiation therapy works with standard temozolomide chemo-radiotherapy and plerixafor in treating patients with glioblastoma (brain tumor). Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Plerixafor is a drug that may prevent recurrence of glioblastoma after radiation treatment. Giving whole brain radiation therapy with standard temozolomide chemo-radiotherapy and plerixafor may work better in treating patients with glioblastoma.
Glioma is the most common primary malignant Brain Tumor. Although the traditional treatment (surgery, radiotherapy and chemotherapy) has been actively carried out, the curative effect of High grade glioma (HGG) is still poor.On the basis of a lot of exploration, the union medication has become a hot spot. Malignant glioma has obvious neovascularization and inhibiting angiogenesis can inhibit tumor proliferation and invasion.Studies have found that inhibiting VEGFR-2 can can reduce neovascularization and inhibit tumor growth. NCCN clinical practice guidelines recommend bevacizumab(BEV) for the treatment of recurrent malignant gliomas. AVAglio＆RTOG 0825 subgroup analysis showed that TMZ combined with antiangiogenic drugs may have advantages in the first-line treatment of patients with IDH1 wild-type high grade glioma.However, some studies have shown that bevacizumab can lead to rapid deterioration due to hypoxia or phenotypic changes. So it is urgent to find new antiangiogenic drugs. Apatinib is an oral small molecule antiangiogenic targeted drug. Apatinib plus temozolomide has been shown to be effective and tolerable in recurrent glioma. So the investigators aimed to evaluate the efficacy and safety of temozolomide combined with apatinib in the new diagnosis of high-grade glioma，and to explore the new first-line treatment of HGG, especially to TMZ insensitivity patients(MGMT gene promoter unmethylated) and poor prognosis (IDH1 wild type) population. And Find out the benefit groups of the two drugs.
This pilot trial studies the side effects of hyperpolarized carbon C 13 pyruvate magnetic resonance imaging (MRI) in diagnosing participants with glioma. Diagnostic procedures, such as hyperpolarized carbon C 13 pyruvate MRI, may help find and diagnose glioma.
This is a 2 strata pilot trial within the Pacific Pediatric Neuro-Oncology Consortium (PNOC). The study will use a new treatment approach based on each patient's tumor gene expression, whole-exome sequencing (WES), targeted panel profile (UCSF 500 gene panel), and RNA-Seq. The current study will test the efficacy of such an approach in children with High-grade gliomas HGG.
This research study is evaluating a psychological intervention for caregivers of loved ones with malignant gliomas.
This pilot study will include grade IV glioma patients treated with SSRIs during approximately a 17 week study period. Changes in cognition and evaluation of psychosocial factors from baseline to after 17 weeks of treatment with SSRI study drug will be calculated.
Hyperfractionated radiation therapy (RT) to 72.0 Gy with BCNU will be compared to conventional radiation therapy to 60.0 Gy with BCNU to determine if hyperfractionated RT can improve the median survival time of adults with supratentorial malignant gliomas.
Background: Gliomas are the most common malignant brain tumors. Some have certain changes (mutations) in the genes IDH1 or IDH2. If there are a high number of mutations in a tumor, it is called hypermutator phenotype (HMP). The drug nivolumab helps the immune system fight cancer. Researchers think it can be more effective in patients with IDH1 or IDH2 mutated gliomas with HMP. They will test gliomas with and without HMP. Objectives: To see if nivolumab stops tumor growth and prolongs the time that the tumor is controlled. Eligibility: Adults 18 years or older with IDH1 or IDH2 mutated gliomas Design: Participants will be screened with: Medical history Physical exam Heart, blood, and pregnancy tests Review of symptoms and activity levels Brain magnetic resonance imaging (MRI). Participants will lie in a cylinder that takes pictures in a strong magnetic field. Tumor samples Participants will get the study drug in 4-week cycles. They will get it through a small plastic tube in a vein (IV) on days 1 and 15 of cycles 1-4. For cycles 5-16, they will get it just on day 1. On days 1 and 15 of each cycle, participants will repeat some or all screening tests. After cycle 16, participants will have 3 follow-up visits over 100 days. They will answer health questions, have physical and neurological exams, and have blood tests. They may have a brain MRI. Participants whose disease did not get worse but who finished the study drug within 1 year of treatment may have imaging studies every 8 weeks for up to 1 year. Participants will be called or emailed every 6 months with questions about their health.
The overall objective of this study is to assess the safety and efficacy of the LUM Imaging System in imaging primary and metastatic cancer in the brain. This includes selecting a dose to determine the initial efficacy of LUM015 for the molecular imaging of low-grade gliomas, glioblastomas and cancer masses that have metastasized to the brain.
The imaging of cerebral oxygenation is an extremely important tool in understanding the pathophysiology of the tumor and for adaptation of therapies according to hypoxia. Currently, imaging of cerebral oxygenation is mainly performed by the use of Positron Emission Tomography (PET). Thus, the investigators have been able to show that the FMISO radiotracer can reveal tumor hypoxia (HypOnco study, promotor: Caen University Hospital, main investigator: J.S. Guillamo). After injection of the radiotracer, increased uptake is observed in the regions for which the tissue oxygen pressure is less than 10 mmHg (the healthy brain with a tissue oxygen pressure (ptO2) ≈ 40mmHg). Although PET is a reference methodology, it is not widely practiced mainly because of radioactive sources. Magnetic Resonance Imaging (MRI) would bypass the previously mentioned PET limitations. The investigators have recently shown that a measure of local oxygen saturation could be obtained by MRI. This methodology has also been implemented at a clinical scale on lower field MRI magnets, but its formal validation in a clinical situation remains to be demonstrated with respect to FMISO. The major advantage of this methodology is that MRI is already performed in routine practice for patients. Measuring tissue oxygenation with MRI (SatO2-MRI) would not add additional examination for the patient. In addition, MRI is a non-ionizing methodology with a very good spatial resolution compared to PET, this should help to better understand intratumoral heterogeneity. Similarly, in preclinical studies, the investigators have shown in a context of mild hypoxia that SatO2-MRI may be more sensitive than PET. The investigators propose a study to compare in patients with glial tumors, images obtained by 3 Tesla MRI of SatO2-MRI to the hypoxia maps obtained by FMISO PET. These imaging studies will be confronted with studies carried out in immunohistochemistry on biopsies / resection allowing to reveal and to quantify by image analysis the expression of the factors induced by hypoxia (HIF1, HIF2). This study should include 20 patients with glioma (15 high-grade patients and 5 low-grade patients) in pre-surgery. The aim is to show that SatO2-MRI is a relevant methodology (in terms of sensitivity, specificity) for assessing intratumoral oxygenation in a context of brain tumors. This fits perfectly into an era of personalized medicine where functional imaging finds its meaning.
