Mutations in isocitrate dehydrogenase 1 (IDH1) are found in >70% of secondary glioblastomas and lower-grade gliomas (grades II–III). Among the numerous phenotypic differences between IDH1 mutant and wild-type glioma patients, the most salient is an improved survival rate for ...
For the more aggressive form of glioma, glioblastoma, the survival rate with 5-year lifespan from the time of diagnosis is less than 5% (Stupp et al., 2005). Hence, glioma is considered as a malignant tumor and characterized by rapid growth, strong invasiveness, frequent postoperative relapse...

Gliomas, tumors that arise from the brain’s glial cells, are the most prevalent type of primary intracranial tumors. According to the 2021 WHO classification of central nervous system tumors, gliomas are graded from 1 to 4, with grades 1 and 2 categorized as low-grade gliomas and grades 3 ...
We showed that MRI could be used to predict tumor grade and survival. Temozolomide treatment of high-grade tv-a gliomas provided a 14-day growth delay compared with vehicle controls. Diffusion MRI measurement of the apparent diffusion coefficient showed an early decrease in cellularity with ...
Among these, grade IV gliomas, also known as glioblastoma multiforme (GBM), exhibit the highest degree of growth aggressiveness2. Unfortunately, despite advances in diagnosis and drug therapy, glioblastoma remains incurable, with a median survival time of 15 months and a 5-year survival rate of ...
This study was conducted as an exploratory arm of a multisite phase 1 clinical trial across 15 institutions forpediatric patientswith midlinegliomatumors who have about a 12 to 18 month survival rate. Patients received a promising experimental therapy called ONC201 over the course of months, and ...
Maximal safe resection of high-grade glioma (HGG) has been linked to improved overall and progression-free survival1,2. Surgery-related new or deteriorating neurological deficits, on the other hand, have been associated with impaired quality of life and even decreased survival3,4. A significant ...

Investigators are assessing the primary end points of safety and tolerability, including the incidence of adverse events, and the maximum tolerated dose. Secondary end points of the trial include the assessment of overall response rate, duration of response, overall survival, and progression-free survi...
