(Cedars-Sinai Medical Center) Researchers at Cedars-Sinai Medical Center's Maxine Dunitz Neurosurgical Institute who first isolated cancer stem cells in adult brain tumors in 2004 have now identified a molecular mechanism that is involved in the development of these cells from which malignant brain tumors may originate. This could offer a target for scientists seeking treatments that would kill malignant brain tumors at their source and prevent them from recurring.

Do cell phones increase brain cancer risk?

(Elsevier) Major research initiatives are needed immediately to assess the possibility that using cellular phones may lead to an increased risk of brain tumors, according to an editorial in the November issue of the journal Surgical Neurology.

(Massachusetts General Hospital) Massachusetts General Hospital researchers are investigating a new approach to gene therapy for brain tumors -- delivering a cancer-fighting gene to normal brain tissue around the tumor to keep it from spreading. They have found that inducing mouse brain cells to secrete human interferon-beta suppressed and eliminated growth of human glioblastoma cells implanted nearby.

(Ludwig-Maximilians-Universität München) Medulloblastomas are common and aggressive brain tumors that occur mostly in children and teenagers. In two studies, working together with international scientific teams, Ludwig-Maximilians-Universität München medical scientist Dr. Ulrich Schüller has now successfully revealed the type of cell from which these tumors arise -- which could lead us to more targeted and thus better therapies for these cerebellar tumors.

(Cedars-Sinai Medical Center) In a study using laboratory animals, researchers found that medications commonly prescribed for erectile dysfunction opened a mechanism called the blood-brain tumor barrier and increased delivery of cancer-fighting drugs to malignant brain tumors.

(Cedars-Sinai Medical Center) Researchers conducting a clinical trial of a dendritic cell vaccine designed to fight malignant brain tumors called glioblastoma multiforme have found a correlation between the "intensity" of a patient's immune response and clinical outcome, according to an article in the July 15 issue of the journal Cancer Research.

Researchers hone technique to KO pediatric brain tumors

(Washington University in St. Louis) An interdisciplinary team of researchers at Washington University in St. Louis, led by Karen L. Wooley, Ph.D., James S. McDonnell Distinguished University Professor in Arts & Sciences, is a step closer to delivering cancer-killing drugs to pediatric brain tumors, similar to the tumor that Senator Ted Kennedy is suffering from. They developed polymeric nanoparticles that can entrap doxorubicin, a drug commonly used in chemotherapy, and slowly release the drug over an extended time.

UAB joins elite brain cancer research group

(University of Alabama at Birmingham) The Ivy Genomics-Based Medicine Project is designed to improve treatment for malignant brain tumors by striving to unravel the genetic differences between gliomas. Consortium members like UAB will categorize tumors using sophisticated molecular profiling and, for the first time, test each tumor against a wide spectrum of treatments to match DNA markers with cancer-fighting response.

Brain tumors on the rise, but more treatments available

admin — Tue, 01 Jul 2008 17:26:00 -0500

Sen. Ted Kennedy's illness, as well as questions about the possible effects of cell phone use, have kept brain tumors in the news. Dr. Isabelle M. Germano, a neurosurgeon at Mount Sinai who studies brain tumors, offers a primer on detection and treatment.
