These findings suggest a path for identifying metastatic cancer early and intervening to improve outcomes.
A study published in the prestigious New England Journal of Medicine offers the most in-depth assessment yet of the safety and effectiveness of a high-tech alternative to brain surgery to treat the uncontrollable shaking caused by the most common movement disorder. And the news is very good.
People with high levels of four biomarkers in the blood may be more likely to develop a stroke than people with low levels of the biomarkers, according to a study published in the August 24, 2016, online issue of Neurology®, the medical journal of the American Academy of Neurology.
One of the many reasons tumors are so difficult to treat is that they are able to adapt whenever they are exposed to unfavorable conditions. Hypoxia, or a lack of oxygen, is one example of a phenomenon that should weaken the tumor, but instead, the malignant cells are able to compensate and drive more aggressive disease behavior.
Pathologists have been largely diagnosing disease the same way for the past 100 years, by manually reviewing images under a microscope. But new work suggests that computers can help doctors improve accuracy and significantly change the way cancer and other diseases are diagnosed. A research team from Beth Israel Deaconess Medical Center (BIDMC) and Harvard Medical School (HMS) recently developed…
Researchers at Massachusetts Institute of Technology research center in Singapore have developed a new microfluidic device that tests the effects of electric fields on cancer cells. They observed that a range of low-intensity, middle-frequency electric fields effectively stopped breast and lung cancer cells from growing and spreading, while having no adverse effect on neighboring healthy cells.
A new nano-fabricated platform for observing brain cancer cells provides a much more detailed look at how the cells migrate and a more accurate post-surgery prognosis for brain cancer (glioblastoma) patients.

This has been achieved in association with teams from the Assistance Publique-Hôpitaux de Paris (the Greater…
What started as a stuffy-nose and mild cold symptoms for 15-year-old Parker Turchan led to a far more serious diagnosis: a rare type of tumor in his nose and sinuses that extended through his skull near his brain. “He had always been a healthy kid, so we never imagined he had a tumor,” said Parker’s father, Karl. “We didn’t even know you could get a tumor in the back of your nose.”

Stopping the growth of blood vessels in tumours is a key target for glioblastoma therapies, and imaging methods are essential for initial diagnosis and monitoring the effects of treatments. While mapping vessels in tumours has proven a challenge, researchers have now developed a combined magnetic resonance imaging (MRI) and ultramicroscopy 'toolkit' to study vessel growth in glioma models in more…
Surgeons removing a malignant brain tumor don't want to leave cancerous material behind. But they're also trying to protect healthy brain matter and minimize neurological harm.
Accuray Incorporated announced today that the first centers in Qatar, Latvia, and Bulgaria are now equipped with its radiation therapy technology, demonstrating continued momentum in adoption of its devices in Europe, India, the Middle East and Africa (EIMEA). The CyberKnife® and TomoTherapy® Systems are now used in more than 40 countries to treat patients across the full spectrum of radiation…
SyntheticMR and The University of Texas MD Anderson Cancer Center have signed a research agreement to study SyMRI to characterize brain tumors.
When it comes to fending off disease and helping prevent people from falling ill, the body’s immune system – armed with T-cells that help eliminate cancer cells, virus-infected cells and more – is second to none. But exactly how the immune system works remains, in many ways, a mystery, as there are numerous cell types whose functions and interactions with our immune systems have not been…
Brain tumor tissue can be hard to distinguish from normal brain during surgery. Neurosurgeons use their best judgment in the operating room but often must guess exactly where the edges of the tumor are while removing it.
A study three years ago sparked a medical mystery when it revealed a part of the brain not found in any present-day anatomy textbooks. Recently, Indiana University computational neuroscientist Franco Pestilli and an international research team published an article in the journal Cerebral Cortex that suggests this missing part of the brain may play an important role in how we understand the world…
Researchers at the University of Maryland and the University of Virginia have performed the first focused ultrasound treatments in the United States for dyskinesia associated with Parkinson’s disease.
Researchers at Columbia University have reported a new approach to visualize glucose uptake activity in single living cells by light microscopy with minimum disturbance.
Every time a cell divides, the ends of chromosomes – the threads of DNA residing in the nucleus – shorten a bit. Once the chromosome ends, called telomeres, become too short, cells normally stop dividing. Scientists from the German Cancer Research Center (DKFZ) have now discovered how cancer cells make use of specific DNA repair enzymes to extend the telomeres. In this way, they escape the…
Brain lesions in children can be especially challenging to diagnose, according to a report in the journal Frontiers in Neurology by a multidisciplinary team of Loyola University Chicago Stritch School of Medicine physicians. Lesions include tumors, abnormal blood vessel formations, and abscesses and inflammation due to infections.
Tumor suppressor genes protect against cancer. Until now, scientists have had to perform complex experiments to detect whether or not a mutation or loss of this gene type does, in fact, cause cancer. Scientists from the German Cancer Research Center (DKFZ) have now used a new gene technology method called CRISPR/Cas9 technology for this detection.
Brain surgery is famously difficult for good reason: When removing a tumor, for example, neurosurgeons walk a tightrope as they try to take out as much of the cancer as possible while keeping crucial brain tissue intact — and visually distinguishing the two is often impossible. Now Johns Hopkins researchers report they have developed an imaging technology that could provide surgeons with a…
New, ultra-high-field magnetic resonance images (MRI) of the brain by researchers at the University of Illinois at Chicago provide the most detailed images to date to show that while the brain shrinks with age, brain cell density remains constant.

Johns Hopkins scientists have published laboratory data refuting studies that suggest blood vessels that form within brain cancers are largely made up of cancer cells. The theory of cancer-based blood vessels calls into question the use and value of anticancer drugs that target these blood vessels, including bevacizumab (Avastin).

Modern techniques based on intense laser pulses may in the future replace expensive conventional particle accelerators. A team of physicists of the Cluster of Excellence "Munich-Centre for Advanced Photonics" (MAP) lead…
Brain tumors are the primary cause of cancer mortality in children. Even if a cure is possible, young patients often suffer tremendously from the stressful treatment which can be harmful to the developing brain. Therefore, there is an urgent need for target-oriented, gentle treatment methods. The most important childhood brain tumors are medulloblastoma, which is diagnosed in approximately one…
