JENKINTOWN, Pa.--(BUSINESS WIRE)--April 4, 2006--The National Comprehensive Cancer Network (NCCN) today announces the release of the new NCCN Venous Thromboembolic (VTE) Disease Guidelines. These guidelines outline the diagnosis, treatment and prevention of VTE--a potentially serious condition that occurs when a blood clot forms in the deep veins of the legs or in the pelvic veins. Cancer patients are especially at risk for VTE, which can result in serious complications like pulmonary embolism if not diagnosed and treated effectively. As a result, NCCN has included VTE as part of The NCCN Clinical Practice Guidelines in Oncology(TM), which are widely recognized and applied as the standard for clinical policy in oncology in both the community practice setting and in academic cancer centers. These guidelines are updated continually and are based upon evaluation of scientific data integrated with expert judgment.
