Their study, which will be presented at the 2013 annual meeting of the American Society of Clinical Oncology, provides pre-clinical evidence necessary to initiate a clinical trial. http://medicalxpress.com/news/2013-05-preclinical-agent-slippery-proteins-ewing.html Cancer Wed, 15 May 2013 18:00:03 EST news287856941 A clinical trial has shown that patients, and their physicians, are eager to jump into next-era cancer care—analysis of an individual's tumor to find and target genetic mutations that drive the cancer. Results of the study, CUSTOM, are being presented at the 2013 annual meeting of the American Society of Clinical Oncology years before investigators thought they would be ready. http://medicalxpress.com/news/2013-05-prospective-trial-molecular-profiling-tailoring.html Cancer Wed, 15 May 2013 18:00:02 EST news287856906 Researchers at Georgetown University Medical Center have used tiny doses of a leukemia drug to halt accumulation of toxic proteins linked to Parkinson's disease in the brains of mice. This finding provides the basis to plan a clinical trial in humans to study the effects. http://medicalxpress.com/news/2013-05-cancer-drug-build-up-toxic-brain.html Genetics Fri, 10 May 2013 00:10:02 EST news287338927 Using MRI, neuroscientists at Georgetown University Medical Center found significant differences in brain anatomy when comparing men and women with dyslexia to their non-dyslexic control groups, suggesting that the disorder may have a different brain-based manifestation based on sex. http://medicalxpress.com/news/2013-05-brain-anatomy-dyslexia-men-women.html Neuroscience Wed, 08 May 2013 13:02:28 EST news287236941 Black women with breast cancer were found to be three times more likely than their white counterparts to delay treatment for more than 90 days—a time delay associated with increased deaths from the disease, according to a new study led by researchers at Georgetown Lombardi Comprehensive Cancer Center. http://medicalxpress.com/news/2013-05-breast-cancer-treatment-varies-patient-doctor.html Cancer Tue, 07 May 2013 12:37:05 EST news287149018 Two studies funded by NASA and presented at the AACR Annual Meeting 2013 help explain why space radiation may increase the risk of colorectal cancer in humans. http://medicalxpress.com/news/2013-04-exposure-space-ability-intestinal-cells.html Cancer Tue, 09 Apr 2013 13:00:04 EST news284730777 Excess estrogen levels during pregnancy can disable, in their daughters, a powerful breast cancer tumor suppressor gene, say researchers at Georgetown Lombardi Comprehensive Cancer Center.
