Dendritic cell vaccine supports further study in larger trials. A phase 1 study of 11 patients with glioblastoma who received injections of an investigational vaccine therapy and an approved chemotherapy showed the combination to be well tolerated while also resulting in unexpectedly significant survival increases, researchers at the Duke Cancer Institute report. Patients treated with the study drug (dose-intensified temozolomide and vaccines) were continuously monitored for toxicity and adverse events. Study patients experienced known side effects with temozolomide, including nausea, lymphopenia, thrombocytopenia and fatigue.

There were no treatment limiting a...

This March 2016 photo provided by the City of Hope hospital shows patient Richard Grady in Duarte, Calif. Suffering from a deadly brain cancer that had spread to his spine, a novel therapy, which helped his immune system attack his disease, shrank his tumors. Grady was the first person to get cells that were genetically modified to seek and kill cancer dripped through a tube into a space in the brain where spinal fluid is made, sending the cells down the path the cancer traveled to his spine.

A man with deadly brain cancer that had spread to his spine saw his tumors shrink and, for a time, completely vanish after a novel treatment to help his immune system attack his disease—another first in this promising field...

Researchers have shown that a metabolic pathway associated with slowing aging also drives brain cancer. In the image above, cancer stem cells in a mouse brain section glow fluorescent green, allowing researchers to study the effect of inhibiting the pathway on the ability of cancer stem cells to survive and proliferate.

While a particular metabolic pathway shows potential to slow down the aging process, new research indicates a downside: That same pathway may drive brain cancer. The pathway, known as the nicotinamide adenine dinucleotide (NAD+) pathway, is overactive in a most deadly form of brain cancer, glioblastoma, according to a study by researchers at Washington University School of Medicine in St. Louis...

In certain settings, the TGF-beta pathway can act as an oncogene, enhancing cancer progression in humans. The activation of this pathway can increase the growth of tumors by promoting cell invasion, activating cancer stem cells, and in some cases, promoting the spread of cancer. In recent years, a number of deubiquitinating enzymes have been shown to regulate the TGF-β pathway and may potentially be considered as a new class of drug targets...
