Patients with terminal brain cancer who watched a brief video illustrating options for end-of-life care were significantly more likely to indicate a preference for comfort measures only than were patients who listened to a verbal description of treatment choices. Practically all those viewing the video would choose not to receive cardiopulmonary resuscitation (CPR) after their cancer became advanced, compared with only half of those in the control group, report the authors of a study that will be published in the Journal of Clinical Oncology and has received early online release. http://www.physorg.com/news178997248.html Medicine & Health Wed, 02 Dec 2009 17:50:02 EST news178997248 Duke University Medical Center researchers have figured out how stem cells in the malignant brain cancer glioma may be better able to resist radiation therapy. And using a drug to block a particular signaling pathway in these cancer stem cells, they were able to kill many more glioma cells with radiation in a laboratory experiment. http://www.physorg.com/news178983338.html Medicine & Health Wed, 02 Dec 2009 13:41:28 EST news178983338 Long durations of exposure to formaldehyde used for embalming in the funeral industry were associated with an increased risk of death from myeloid leukemia, according to a new study published online November 20 in the Journal of the National Cancer Institute. http://www.physorg.com/news177958809.html Medicine & Health Fri, 20 Nov 2009 17:10:01 EST news177958809 (PhysOrg.com) -- Human embryonic stem cells could help people with learning and memory deficits after radiation treatment for brain tumors, suggests a new UC Irvine study. http://www.physorg.com/news177681967.html Chemistry Tue, 17 Nov 2009 12:40:01 EST news177681967 A new miniature, hand-held microscope may allow more precise removal of brain tumors and an easier recognition of tumor locations during surgery. http://www.physorg.com/news177178774.html Medicine & Health Wed, 11 Nov 2009 16:30:03 EST news177178774 St. Jude Children's Research Hospital and the University of Florida Proton Therapy Institute have formed a collaboration to provide proton therapy for St. Jude patients.

The near-extinct Asian plant, Podophyllyum emodi, produces podophyllotoxin, a compound used in manufacturing etoposide, the active ingredient in a drug used for treating lung and testicular cancer. Podophyllyum emodi is a cousin of the common mayapple weed found in the United States. http://www.physorg.com/news171283180.html Chemistry Fri, 04 Sep 2009 11:50:02 EST news171283180 Malignant brain tumors often fail to respond to promising new medication. Researchers in Heidelberg have discovered a mechanism and a tumor marker for the development of this resistance. A "death receptor" can possibly provide information as to how great the chances of success are for chemotherapy. At the same time, it offers a new approach for promising brain tumor therapy. http://www.physorg.com/news171048234.html Medicine & Health Tue, 01 Sep 2009 21:30:02 EST news171048234 (AP) -- He lived 15 months with an incurable brain tumor, a little longer than usual for a patient in his late 70s. Perhaps equally important is that Sen. Edward M. Kennedy lived those months well - able to work almost to the end, to sail the choppy New England waters he adored, to help elect a president he supported, and even to give him a dog. http://www.physorg.com/news170521790.html Medicine & Health Wed, 26 Aug 2009 16:20:06 EST news170521790 Researchers funded by the National Institutes of Health have found that the activity of a protein in brain cells helps stimulate the spread of an aggressive brain cancer called glioblastoma multiforme (GBM). In a move toward therapy, the researchers showed that a small designer protein can block this activity and reduce the spreading of GBM cells grown in the laboratory. http://www.physorg.com/news169820163.html Medicine & Health Tue, 18 Aug 2009 13:50:03 EST news169820163 Researchers from Columbia University Medical Center's Herbert Irving Comprehensive Cancer Center have identified a protein that activates brain stem cells to make new neurons - but that may be hijacked later in life to cause brain cancer in humans. The protein called Huwe1 normally functions to eliminate other unnecessary proteins and was found to act as a tumor suppressor in brain cancer. http://www.physorg.com/news169735638.html Medicine & Health Mon, 17 Aug 2009 14:00:01 EST news169735638 Tokyo University Hospital will begin a clinical test in late August of a viral therapy in which viruses are injected directly into brain tumor patients, according to hospital officials. http://www.physorg.com/news169653035.html Medicine & Health Sun, 16 Aug 2009 15:00:02 EST news169653035 (AP) -- President John F.

It's also one of the hardest to treat. Imaging results are often imprecise because brain cancers are extremely invasive. Surgeons must saw through the skull and safely remove as much of the tumor as they can. Then doctors use radiation or chemotherapy to destroy cancerous cells in the surrounding tissue. http://www.physorg.com/news168537401.html Nanotechnology Mon, 03 Aug 2009 17:20:01 EST news168537401 (PhysOrg.com) -- By miniaturizing a device that monitors the delivery of healthy cells, researchers at Department of Energy's Oak Ridge National Laboratory are developing a powerful instrument for physicians to use in treating patients with Parkinson's syndrome, brain tumors and other diseases. http://www.physorg.com/news167496922.html Medicine & Health Wed, 22 Jul 2009 22:40:02 EST news167496922 Gliomas are among the most common and most malignant brain tumors. These tumors infiltrate normal brain tissue and grow very rapidly. As a result, surgery can never completely remove the tumor. Now, the neurosurgeons Dr. Darko S. Markovic (Helios Klinikum Berlin-Buch) and Dr. Michael Synowitz (Charité) as well as Dr. Rainer Glass and Professor Helmut Kettenmann (both Max Delbrück Center for Molecular Medicine, MDC, Berlin-Buch), have been able to show that glioma cells exploit microglia, the immune cells of the brain, for their expansion (PNAS Early Edition). http://www.physorg.com/news166972642.html Medicine & Health Thu, 16 Jul 2009 14:30:01 EST news166972642 (AP) -- Scientists have found seven key genes in the type of brain tumor affecting Sen.
