The way we think about treating brain cancers is being quietly revolutionized, buried beneath recent headline-grabbing announcements pertaining to COVID-19. A series of discoveries and breakthroughs in oncology, especially those targeting glioblastoma.
“They drill a small hole in the bone or the skull,” Desjardins says. “It’s just above the tumor. Then, they put a small needle in.” It’s similar to a brain biopsy, but instead of taking a sample out, they put something in the brain. In this case, it was a bacterial toxin that attached to the receptors of the tumor cells.
New analysis of 3D images and quantitative data "will help to appreciate from within how the tumor is built in its full dimensionality, and to identify where different cell types are located", explains George Paul Cribaro, first author of the study. "It provides more complete information than the usual 2D analyses performed for neuropathological diagnosis".
A research team from both Scottish and UK institutions using infrared spectroscopy at Diamond Light Source reports a major advance in brain tumor diagnosis made by.

Researchers found that up to 20% of glioblastomas have overactive cellular power plants (mitochondria) and that their cells are relying on them for all their energy. This type of glioblastoma is associated with a slightly longer survival time, and its dependence on fuel generated by mitochondria may make it especially vulnerable to drugs that inhibit the structures.
A promising non-invasive treatment to effectively and safely destroy deadly brain tumors is being tested on human patients for the first time ever at the Ivy Brain Tumor Center at the Barrow Neurological Institute in Phoenix. This new treatment has shown to be incredibly effective in treating aggressive brain tumors in animals, said Dr. Shwetal Mehta, a molecular neuro-oncologist and the chief operating officer and deputy director of the center.
Glioblastoma brain tumors are especially perplexing. Inevitably lethal, the tumors occasionally respond to new immunotherapies after they’ve grown back, enabling up to 20% of patients to live well beyond predicted survival times.
Mitochondria are responsible for creating the energy that fuels all cells. Though they are usually less efficient at producing energy in cancer, tumor cells in this newly identified type of glioblastoma rely on the extra energy provided by overactive mitochondria to survive.

“Our research found that the CD200 protein was acting as a protective shield inside a person’s brain tumor, effectively preventing the immune system or immune-directed therapy from attacking the tumor,” said Dr. Olin. “The CD200 checkpoint inhibitor that we developed, along with a proven vaccine, has shown amazing results in our tests and has the potential to have fewer adverse effects for patients.”
“These patients appear to have a much more favorable prognosis and survive for years, if not decades. So, we decided to further investigate whether IDH mutations can predict which patients with low-grade glioma serve to benefit from the addition of chemotherapy to radiation vs. radiation alone.”
A powerful tool in The University of Kansas Health System’s surgical arsenal is the intraoperative MRI. We have an MRI scanner within the operating room, adjacent to the surgical table. Neurosurgeons begin the resection and remove as much of the tumor as we safely can. We then slide the patient on the surgical table directly into the MRI scanner to capture real-time images that may show us more tumor cells that can be removed during the same surgery.

MRI could help identify which patients with aggressive brain tumors might benefit from liquid biopsy, the blood test that pinpoints cancer DNA in a patient’s bloodstream. New research published today in Neuro-Oncology Advances shows that adding imaging to the mix when trying to diagnose and biopsy for glioblastoma (GBM) can help physicians determine which patients are good candidates for a liquid biopsy, as well as those who aren’t.
A new study will test a combined cancer vaccine which triggers immune responses against molecules that are expressed by GBM tumors. As it is a combined vaccine, it will target two molecules (TRP2 and WT1) which both play a significant role in GBM and are expressed in many GBM cells. It is expected that this study will provide a basis on which to move this new approach into the clinical setting.
GammaTile Therapy, marketed by GT Medical Technologies, became available to patients in January 2019 and is being used in top cancer treatment centers across the United States.

The irony is that one of the world’s deadliest viruses may be useful in treating one of the deadliest of brain cancers,”
A study published in JAMA Oncology confirmed an association between maximal resection of contrast-enhanced tumor and overall survival (OS) in patients with glioblastoma across all subgroups.
Additionally, the researchers found that maximal resection of non-contrast-enhanced tumor was associated with longer OS in younger patients, regardless of isocitrate dehydrogenase (IDH) status, and among patients with IDH-wild-type glioblastoma regardless of the methylation status of the promoter region of the DNA repair enzyme O6-methylguanine-DNA methyltransferase.
A cancer tumor's ability to mutate allows it to escape from chemotherapy and other attempts to kill it. So, encouraging mutations would not be a logical path for cancer researchers. Yet a Mayo Clinic team and their collaborators took that counterintuitive approach and discovered that while it created resistance to chemotherapy, it also made tumors sensitive to immunotherapy.
Survival may more than double for adults with glioblastoma, the most common and deadly type of brain tumor, if neurosurgeons remove the surrounding tissue as aggressively as they remove the cancerous core of the tumor.
This discovery, reported in a retrospective study headed by researchers at UC San Francisco, is welcome news for those in the glioblastoma community, which celebrated its last breakthrough in 2005 with the introduction of the chemotherapy drug temozolomide.
Sam underwent DNA and RNA genomic sequencing at Mott to confirm which mutation was driving his cancer and help match him with an unconventional treatment to target that specific mutation.

While tumors are known to compromise the integrity of the blood brain barrier—a specialized vessel wall evolved to keep the brain "safe"—the makeup of the barrier is inconsistent, which prevents drugs from being uniformly distributed throughout the tumor. Unfortunately, increasing dosages to help improve drug delivery is not possible due to the adverse effects caused by drug interactions with healthy tissue, and drug penetration to the tumor core remains limited.
By combining focused ultrasound methods with different nanoparticle formulations, Researchers have investigated two strategies for improving drug penetration into brain tumors.

The human brain has some remarkable capabilities - including the ability to block cancer drugs from effectively reaching cancer cells in the brain. The greatest obstacle when it comes to treating cancer that has spread to the brain is the blood-brain barrier, the brain's natural defense mechanism that is a collection of blood vessels that can filter out what goes in and out of the brain.
The blood test measures the amount of cell-free DNA, or cfDNA, in the bloodstream, according to Penn Medicine News. Cancer cells and other cells shed cfDNA into the bloodstream. The researchers studied patients with glioblastoma, the most common and deadliest brain tumor, and found that those with higher bloodstream concentrations of cfDNA had a shorter "progression-free survival" than patients with less cfDNA.
