The study's findings may help guide future public health decisions related to smoking, because the more people smoke, the higher their risk of lung cancer. http://medicalxpress.com/news/2012-05-genetic-marker-quantity-african-americans.html Psychology & Psychiatry Tue, 22 May 2012 10:09:01 EST news256900018 Researchers and doctors at the North Shore-LIJ Health System and the Feinstein Institute for Medical Research have discovered that blood can help determine the best treatment plan for patients with ovarian cancer. More specifically, a genetic marker embedded in deoxyribonucleic acid (DNA), called microRNA, indicates if a patient with ovarian cancer has a benign or cancerous tumor, and that she will benefit from chemotherapy after surgery on the tumor. This data will be presented at the American Association for Cancer Research (AACR) Annual Meeting to be held from Saturday through Wednesday (March 31- April 4) in Chicago, IL. http://medicalxpress.com/news/2012-04-dna-marker-ovarian-cancer-treatment.html Cancer Tue, 03 Apr 2012 16:09:14 EST news252688146 Scientists from Brigham and Women's Hospital and Dana-Farber Cancer Institute and their colleagues have found a genetic marker that predicts which aggressive "triple negative" breast cancers and certain ovarian cancers will likely respond to platinum-based chemotherapies. http://medicalxpress.com/news/2012-03-dna-marker-platinum-drug-response.html Cancer Thu, 22 Mar 2012 10:48:26 EST news251632099 (Medical Xpress) -- Research funded by the Medical Research Council (MRC) has shown that a genetic marker, called Serotonin Transporter Promoter Polymorphism (5HTPP), can be used to predict whether a child suffering from anxiety disorder will benefit from cognitive behaviour therapy (CBT). This is the first time that genetic analysis has been used to assess whether a psychological treatment like CBT will work for children. http://medicalxpress.com/news/2011-10-sensitivity-gene-anxious-children-benefit.html Psychology & Psychiatry Tue, 25 Oct 2011 07:34:31 EST news238746859 The team of researchers from the Universities of Bristol, Queensland.

The discovery, scheduled for publication in the August 1 edition of Clinical Cancer Research, brings doctors closer to customizing cancer treatment to individual patients. http://medicalxpress.com/news/2011-07-link-genetic-marker-rectal-cancer.html Cancer Wed, 06 Jul 2011 09:58:06 EST news229164701
