Filter by:Malignant gliomas are the most common and deadly primary brain tumors in adults. The clinical outcome of patients with glioblastoma depends on key molecular genetic alteration. Specifically, Isocitrate Dehydrogenase Gene Mutation, an independent favorable prognostic factor, serve as diagnostic and prognostic markers of glioma. Thus, accurate grading of a glioma is fundamental in order to determine the treatment strategy. Amide proton transfer (APT) imaging is a noninvasive molecular MRI technique based on chemical exchange saturation transfer mechanism that detects endogenous mobile proteins and peptides in biological tissues. Preliminary studies have shown that APT-weighted (APTw) signal intensity could serve as a new imaging biomarker, by revealing significantly higher signal intensities in the high-grade gliomas compared with the low-grade gliomas. The purpose of this study was to investigate the value of amide proton transfer imaging (APT) in the noninvasive evaluation of isocitrate dehydrogenase (IDH) gene status in glioma.
Doctors and other medical scientists want learn about the biology of DIPG/DMG and to develop better ways to diagnose and treat patients with DIPG/DMG. To do this, they need more information about the characteristics of DIPG/DMG tumors. Therefore, they want to establish a central location for clinical information and tumor tissue collected from DIPG/DMG patients. The purposes of this study are: - To enroll patients diagnosed with DIPG/DMG in the International DIPG/DMG Registry and Repository. - To provide a central location for clinical information, scans, and tissue samples from patients with DIPG/DMG enrolled in the registry. - To collect tissue samples in order to study how DIPG/DMG works on the molecular level. Researchers may use the tissue samples to study molecules such as proteins and DNA. Proteins are needed for the body to function properly and DNA is the molecule that carries our genetic information. Other researchers will be able to use the stored samples in the future to learn more about DIPG/DMG. The information researchers get from the research studies will be kept in the registry along with the clinical information. - To help investigators around the world to work together to make more consistent diagnosis and better design of future research studies. We hope this will lead to better treatments for DIPG/DMG in the future.
In this research study the researchers want to learn more about the effects (both good and bad) the study drug selumetinib has on participants with neurofibromatosis type II (NF2) related tumor. The researchers are asking patients with NF2 related tumors to be in the study, because their hearing has decreased and/or their NF2 related tumor has started to grow. The goals of this study are: - Determine if selumetinib will stop NF2 related tumors from growing - Measure the changes in hearing after receiving selumetinib for 6 months. - Determine if selumetinib improves how participants feel (physically and emotionally) and how participants can perform daily activities. - Examine tumor tissue, if available, in a laboratory to see if NF2 related tumors have targets of selumetinib.
This study was designed to collect a series of patients with gliomas which were involved in motor cortex to analyze difference accuracy of motor cortex localization between BOLD-fMRI and ZOOMit-fMRI.
This is a Phase I and Early Efficacy Study of Convection Enhanced Delivery (CED) of irinotecan liposome injection (nal-IRI) Using Real Time Imaging with Gadolinium in Children with Diffuse Intrinsic Pontine Glioma who have completed focal radiotherapy
Postoperative conventional radiation at 60 Gy/30f is currently still considered the standard radiotherapy mode for high-grade gliomas; however, the efficacy is still unsatisfactory. Studies in recent years have shown that hypofractionated simultaneous integrated boost-intensity modulated radiation therapy (SIB-IMRT) has certain survival benefits over other fractionation methods; but, the best hypofractionation mode and its efficacy have not been confirmed. The purpose of this study is to investigate the maximum tolerated dose (MTD) of hypofractionated SIB-IMRT with stepwise escalating of doses combined with temozolomide (TMZ) for the treatment of malignant gliomas.
Malignant gliomas have a very poor prognosis with median survival measured in months rather than years. It is a disease in great need of novel therapeutic approaches. Based on the encouraging results of our preclinical studies which demonstrate improved efficacy without added toxicity, the paradigm of delivering a novel oncolytic adenovirus via a neural stem cell line in combination with radiation and chemotherapy is well-suited for evaluation in newly diagnosed malignant gliomas. The standard-of-care allows application of virotherapy as neoadjuvant therapy and assessment of the cooperative effects with radiation/chemotherapy without altering the standard treatment.
The epidermal growth factor receptor variant Ⅲ(EGFR vⅢ) is commonly detected in high-grade gliomas, which is also an important epitope in EGFR-targeted therapies and correlated to poor prognosis. However, detection of this mutant usually needs resected tumor samples. For biopsy samples, test results may not represent the EGFR vⅢ status of the whole tumor tissues because of the heterogeneity of tumor. It is also not applicable for patients who are not suitable for surgical procedure due to the tumor location or patients' general conditions. Because of the importance of the epidermal growth factor receptor (EGFR) signal pathway in oncogenesis, maintenance, and progression of high grade glioma, there has been an intense effort to develop noninvasive molecular imaging approach for the selection and monitoring of EGFR-targeted therapies. Based on investigators' previous study, investigators plan to perform PET scanning on the participants with high grade gliomas after the injection of the second generation of EGFR tracer ,89Zr-ABT806, which can be specifically binded to EGFR vⅢ . After fusing the PET and MRI images, investigators precisely obtain the tissue from the"hot-spot" on the PET image through multimodal-neuronavigation-guided tumor biopsy. EGFRvⅢ status will be detected by molecular methods to analyze the correlation with the 89Zr-ABT806 PET image qualitatively and quantitatively. Investigators' final goal is to detect EGFR vⅢ by noninvasive molecular imaging procedure for the clinical outcome prediction and the selection of EGFR-targeted therapies.
The purpose of this Phase 2, open-label, single-arm study is to determine the safety and the maximal tolerated dose (MTD) of VAL-083 in combination with a standard of care radiation regimen when used to treat newly diagnosed GBM in patients with unmethylated promoter of the methylguanine-DNA methyltransferase (uMGMT) gene. Pharmacokinetic (PK) properties will be explored and tumor responses to treatment will be evaluated.
Currently, treatment with a specific anti-epileptic drug mainly depends on the physicians' preference, as there are no studies supporting the use of one specific anticonvulsant in glioma patients. The overall aim of this randomized controlled trial is to directly compare the effectiveness of treatment with levetiracetam or valproic acid in glioma patients with a first seizure.
