Latest radiosurgery solutions from Elekta discussed at the 2009 AANS MeetingAfghanistan — Wednesday, April 29, 2009
Atlanta, GA, April 30, 2009
At the 2009 American Association of Neurological Surgeons (AANS) Annual Meeting, May 4-6 at the San Diego Convention Center, Elekta customers and personnel will discuss how Elekta’s latest line of stereotactic treatment solutions is addressing some of the most challenging cases facing neurosurgeons and oncologists today.
Recent studies estimate that 25 percent of all cancer patients – particularly patients with melanoma, lung cancer, or advanced breast cancer – will develop brain metastases and require whole brain therapy. While whole brain radiotherapy is a treatment option, it also subjects healthy brain tissue to radiation dosages that may have negative side affects or limit the amount of therapeutic dose that can be applied in the event of a re-occurrence. In addition, whole brain radiation requires an interruption in the chemotherapy treatments that are so important to maintaining tumor control.
Dr. Christopher M. Duma, Neurological Surgeon at Hoag Memorial Hospital Presbyterian in Newport Beach, California will discuss the use of Leksell Gamma Knife® Perfexion™ to treat multiple brain metastases in a single session. Gamma Knife® surgery always has been especially good at treating very small targets with little or no damage to healthy tissue; but Perfexion is able to treat several targets faster and more efficiently making it a viable option of patients with brain metastases. The result is a fast and effective treatment for brain metastases that is easier on the patient, reduces the damage to healthy tissue that may limit future treatment options, and allows for concomitant chemotherapy for optimum primary tumor control.
While Gamma Knife® surgery was initially invented to treat inoperable cancers and disorders in the brain, now the kind of stereotactic treatment precision established by Elekta can be applied to extra-cranial tumors. Today, the latest advancements in image guidance and dynamic arc delivery pioneered by Elekta combined with Leksell-quality fixation options support Stereotactic Radiosurgery (SRS) and Stereotactic Radiation Therapy (SRT) anywhere in the body to deliver optimal dose to the tumor, while protecting vital organs like the spinal cord.
Dr. Peter C. Gerszten, Associate Professor of Neurological Surgery and Radiation Oncology at the University of Pittsburgh Medical Center and co-editor of Spine Radiosurgery, will discuss the use of Elekta Axesse™ to perform stereotactic radiosurgery for spine and paraspinal lesions. According to Dr. Gerszten, “Axesse is fully optimized for SRS and SRT and therefore well suited for spine radiosurgery, providing patients a fast, safe, and effective treatment alternative or as an adjunct to open surgical intervention.”
More than sixty years ago, Professor Lars Leksell developed a three-coordinate head frame and revolutionized the field of stereotaxy. Twenty years later he conceived of replacing the surgical precision of the neurosurgeon with precisely targeted radiation, and invented the field of stereotactic radiosurgery (SRS). Today, Leksell Gamma Knife® Perfexion™ is still the benchmark upon which all other SRS methods are measured; Perfexion equipped with Extend Program*™ is capable of treating cancers of the head and neck and lesions previously unsuitable for Gamma Knife surgery; And Elekta Axesse™ supports SRS and SRT anywhere in the body making it a versatile cross-over solution for neurosurgery and oncology.
According to President and CEO of Elekta North America, Joseph K. Jachinowski, “Since its very foundation, Elekta has sought to develop technology that allowed practitioners to achieve specific clinical objectives. Today Elekta Neuroscience is still developing technology to address the most challenging cases in neurosurgery and oncology, creating new treatment possibilities that are redefining what we call, human care.”
