A noninvasive, outpatient treatment for noncancerous uterine tumors provides sustained relief from symptoms, according to a new Mayo Clinic led collaborative study.
The study of this innovative treatment approach -- called magnetic resonance imaging guided focused ultrasound surgery (MRgFUS) -- also shows that the more completely tumors are destroyed by focused ultrasound, the more durable the symptom relief. In addition, the incidence of severe side effects is low. Combined, these results produce an overall improved quality of life. The report by Mayo and its collaborators, the Magnetic Resonance Imaging Guided Focused Ultrasound for Uterine Fibroid Group at Brigham and Women's Hospital and Harvard Medical School, appears in the Aug. 1 issue of Obstetrics & Gynecology (http://www.greenjournal.org/future/110.2.shtml).
This new study examined more endpoints and follows women for a longer period after treatment than previous studies of the effects of focused ultrasound to treat uterine fibroid tumors. For example, the current study followed patients post-treatment for twice as long -- 24 months versus 12 months -- than earlier studies. It also followed a patient group that was more than twice as large -- 359 women versus 160 women. The results are therefore stronger than those from earlier studies, and more clinically relevant in their potential to:
