增強核磁共振指導的聚焦超聲波可增加治療效率和耐受度 【?2007-06-05 發布?】 美迪醫訊
最新的數據顯示核磁共振指導的超聲波(MRgFUS)對廣大的子宮纖維瘤患者來說是另一個不錯的選擇。 2007年5月在美國加州舉行的美國婦產科學會會議上的一項研究表明使用MRgFUS的婦女可以迅速并持久減輕這種疾病所造成的痛苦。并且可以在未來大為減低創傷性療法的使用率。 通用電氣醫療公司,是一家發展非-創傷性治療方法系統的公司,制造了世界第一臺MRgFUS,InSightec ExAblate 2000系統,并且在2004年10月通過美國食品和藥物管理局驗收,此系統可以在非創傷的條件下治療指征明顯的子宮纖維瘤。 過去人們低估了MRgFUS作為長時、非創傷性選擇治療子宮纖維瘤的效應。Gee博士解釋道,“我們通過這種治療方法可成功治療更多的腫瘤并且消除了未來還要進行子宮切除的可能。” 另一些由David Lee博士指導的研究表明明顯的子宮纖維瘤在年輕女性中相當普遍并與身體虛弱有一定的關系。大約三分之一的婦女經傳統手術治療后卻得到了相反的效果。 這些結果表明子宮纖維瘤對婦女來說是一種負擔,并且對雇員來說也是一種經濟上的負擔。MRgFUS可提供這種非-侵襲性的治療方法以減輕子宮纖維瘤給病人帶來的虛弱情況。 根據美國國家健康機構(NIH),子宮纖維瘤是一種婦女生育期最常見的非惡性的腫瘤也是婦女進行手術治療的第二大原因。 直接治療與子宮纖維瘤相關的費用每年超過10億美圓。通常,治療子宮纖維瘤可選擇的方法有,侵襲性和最小侵襲性治療方案,包括,子宮切除、子宮動脈栓塞(UAE)等。 來源:medinews.com Enhanced MR-Guided Focused Ultrasound Guidelines Demonstrates Improved Efficacy and Durability New data show that magnetic resonance-guided focused ultrasound (MRgFUS) is a more effective alternative for a broader population of uterine fibroid sufferers. In a study presented at the American College of Obstetrics and Gynecology (ACOG) annual meeting held on May 2007 in San Diego, CA, USA, Phyllis Gee, M.D., from the North Texas Uterine Fibroid Institute (Plano, TX, USA), showed that women undergoing MRgFUS experience rapid and sustained relief from their condition and have a reduced need for alternative, invasive treatments in the future. GE Healthcare (Chalfont St. Giles, UK) and InSightec (Tirat Carmel, Israel), a company that develops non-invasive therapy systems, developed the world抯 first MR-guided focused ultrasound system. InSightec抯 ExAblate 2000 system, approved by the U.S. Food and Drug Administration (FDA) in October 2004, works exclusively in combination with GE抯 Signa MR system to non-invasively treat symptomatic uterine fibroids. hese findings further underscore the utility of MRgFUS as a long-lasting, non-invasive option for the millions of women suffering from uterine fibroids,?said Dr. Gee. 揥ith these expanded treatment guidelines, we are able to successfully treat more of the tumor and virtually eliminate the need for future hysterectomies.? Others findings presented at ACOG by David Lee, Ph.D., senior director, Health Economics and Outcomes Research, GE Healthcare, demonstrated that clinically significant uterine fibroids are common among women in their prime working years and are associated with several debilitating co-morbid conditions. The study also revealed that uterine fibroid treatments impose considerable direct and indirect costs on employers, and that nearly one in three women treated surgically for uterine fibroids experiences an adverse event. hese new data suggest that uterine fibroids impose a substantial clinical burden on women, and a tremendous economic burden on employers. MRgFUS holds the promise of lessening this burden by offering women a non-invasive treatment option for this debilitating condition,?said Dr. Lee. According to U.S. National Institutes of Health (NIH; Bethesda, MD, USA), uterine fibroids are the most common, non-cancerous tumors in women of childbearing age and the second most common reason reproductive women undergo surgery. According to a report by the Rand Corp. (Santa Monica, CA, USA), an international non-profit research organization, direct costs associated with treating uterine fibroids are more than US$1 billion annually. Traditionally, treatment alternatives for uterine fibroids have included invasive and minimally invasive procedures such as hysterectomy, momentum, or uterine artery embolization (UAE). 本文關鍵字:
