Brain Cancer

News and reporting on brain cancer.

A new analysis suggests hypermutation can occur in some chemotherapy-treated gliomas, producing heterogeneous, mutation-rich tumors with poor response to anti-PD-1 treatment.

The study suggests that pediatric low-grade gliomas driven by genetic rearrangements tend to be diagnosed earlier and have better outcomes than those driven by SNVs.

Investigators teased out imaging signals and underlying biology that can differentiate the subset of brain cancers for which tumor DNA can be detected in blood. 

The funding will support the use of a new in situ RNA sequencing technology, STARmap, to build functional maps of the developing brain and brain tumors.

A population of progenitor cells identified in mouse models of the Sonic Hedgehog medulloblastoma subtype led to a gene that is highly expressed in patients with poor outcomes.

At the WIN Symposium, a researcher from Sheba Medical Center discussed ongoing efforts to develop a 22-gene signature for predicting brain metastasis in NSCLC.

Combined DNA/RNA-seq efforts in various settings could lead to new ways of treating kids with drugs meant for adults or to the development of new therapies.

The actual match rate is significantly higher than the 10 percent rate the researchers anticipated they would see when the study began in 2017.

Molecular features in primary and recurrent glioblastomas indicated that key initiator mutations turned up years before diagnosis, often persisting in recurrent tumors.

Using RNA sequence data from the Cancer Genome Atlas and the Chinese Glioma Genome Atlas, researchers identified six genes with expression ties to overall survival.
