Penn's online survivorship care plans empower cancer survivors, caregivers An online tool that provides cancer survivors and their family members with an easy-to-follow roadmap for managing their health as they finish treatment and transition to life as a survivor got high marks from users, according to new University of Pennsylvania School of Medicine research which will be presented this weekend at the American Association for Cancer Research (AACR) 100th Annual Meeting 2009 in Denver. Ninety-seven percent of people who used OncoLife, the first online cancer survivorship care plan tool - developed by physicians and nurses from Penn's Abramson Cancer Center - rated their experience with the tool as "good" to "excellent," and 84 percent said they planned to share their plan with their health care team. http://www.physorg.com/news159374663.html Medicine & Health Sun, 19 Apr 2009 15:44:56 EST news159374663 Genetic variations in miRNA processing pathway and binding sites help predict ovarian cancer risk Genetic variations in the micro-RNA (miRNA) processing pathway genes and miRNA binding sites predict a woman's risk for developing ovarian cancer and her prospects for survival, researchers from The University of Texas M.
