(University of California - San Diego) According to a new Cell study, extra DNA scooped up and copied alongside cancer-causing genes helps keep tumors going -- elements that could represent new drug targets for brain tumors and other cancers notoriously difficult to treat.

(Ivy Brain Tumor Center) The Ivy Brain Tumor Center at the Barrow Neurological Institute, today announced a strategic collaboration with SonALAsense to develop and test a new, non-invasive drug-device combination, sonodynamic therapy (SDT), for recurrent glioblastoma through a Phase 0/2 clinical trial. Details of the study, as well as the results of two other clinical trials will be announced by Dr. Nader Sanai, director of the Ivy Brain Tumor Center, at the 2019 Society of Neuro-Oncology Annual Meeting (SNO) in Phoenix, Ariz. on Nov. 22.

AbstractPediatric brain tumors are the leading cause of cancer-related death in children. Recent advances in sequencing techniques, and collaborative efforts to encode the mutational landscape of various tumor subtypes, have resulted in the identification of recurrent mutations that may present as actionable targets in these tumors. A number of molecularly targeted agents are approved or in development for the treatment of various tumor types in adult patients. Similarly, these agents are increasingly being incorporated into pediatric clinical trials, allowing for a targeted approach to treatment. However, due to the genet...

In this study, we aimed to evaluate a novel approach for non-invasively predicting IDH status from conventional MRI via connectomics, a whole-brain network-based technique. We retrospectively extracted 93 connectome features from the preoperative, T1-weighted MRI data of 234 adult patients (148 IDH mutated) and evaluated the performance of four common machine learning models to predict IDH genotype. Results: Area under the curve (AUC) of the receiver operator characteristic were 0.76 to 0.94 with random forest (RF) showing significantly higher performance (p

Authors: Xu CH, Xiao LM, Zeng EM, Chen LK, Zheng SY, Li DH, Liu Y Abstract Gliomas are aggressive type of brain tumors and cause significant human mortality world over. The frequent relapses, development of drug resistance, the adverse effects of the chemotherapy and dearth of the therapeutic targets form the major hurdles in glioma treatment. Several studies suggest that microRNAs (miRs) are involved in the development and progression of different cancers. Herein, the therapeutic potential of miR-181 was explored in human glioma cells. The results showed that miR-181 is significantly downregulated in human glioma ...

Authors: John F, Robinette NL, Amit-Yousif AJ, Bosnyák E, Barger GR, Shah KD, Mittal S, Juhász C Abstract BACKGROUND: Clinical glioblastoma treatment mostly focuses on the contrast-enhancing tumor mass. Amino acid positron emission tomography (PET) can detect additional, nonenhancing glioblastoma-infiltrated brain regions that are difficult to distinguish on conventional magnetic resonance imaging (MRI). We combined MRI with perfusion imaging and amino acid PET to evaluate such nonenhancing glioblastoma regions. METHODS: Structural MRI, relative cerebral blood volume (rCBV) maps from perfusion MRI...

(Jackson Laboratory) The Glioma Longitudinal Analysis (GLASS) Consortium characterized diffuse glioma cells both before and after therapy to characterize how they change and why this form of malignant brain cancer is so difficult to treat. The findings provide a foundation for further research and the opportunity for the clinical community to predict the effectiveness of newly developed treatments.

(NIH/National Center for Advancing Translational Sciences (NCATS)) Researchers have devised a new, promising plan of attack against deadly childhood brain cancers called diffuse midline gliomas (DMG). NCATS and Stanford University scientists and their colleagues showed that combining two drugs killed DMG patient cells grown in the laboratory and in animal models. The drugs countered the effects of a genetic mutation that causes the diseases. Their studies also uncovered an unrecognized vulnerability in the cancer cells that scientists may be able to exploit.

They are rare in adults, but account for 9% of brain tumors in children, where they usually have an aggressive course. Efficient stratification could lead to improved care but remains a challenge even in the genomic era. Recent studies prop...
