Mayo Clinic - A noninvasive, outpatient treatment for noncancerous uterine tumors, referred to as focused ultrasound, provides sustained relief from symptoms, according to a new Mayo Clinic led collaborative study.梅奥--丧失者,门诊治疗子宫癌肿瘤,称为超声聚焦,可提供持续缓解症状,根据一项新的梅奥率领的协作研究.

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.研究这一新的治疗方法称为磁共振引导聚焦超声手术( mrgfus ) ,也显示了更多的肿瘤完全被摧毁聚焦超声,更持久的减轻症状. In addition, the incidence of severe side effects is low.此外,在发生严重副作用低. Combined, these results produce an overall improved quality of life.综合这些结果,产生一个总体生活质量的提高. 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 August 1, 2007 issue of Obstetrics & Gynecology .报告梅奥及其合作者,磁共振引导聚焦超声治疗子宫肌瘤组布里格姆与妇女医院和哈佛医学院的,出现在2007年8月1日发行的妇产科 .

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.这项新研究对多端点和妇女如下一段较长时间的治疗后,比以前的影响的研究超声聚焦刀治疗子宫肌瘤,肿瘤. For example, the current study followed patients post-treatment for twice as long - 24 months versus 12 months - as earlier studies.举例来说,目前的研究,然后患者治疗前后两次长达24个月还是12个月--先前的研究. It also followed a patient group that was more than twice as large.它也跟着病人组高出两倍大. The results are therefore stronger than those from earlier studies, and more clinically relevant in their potential to:结果是更强,所以较早期的研究,并在临床上更加相关的潜能:

* improve patient care by decreasing the need for repeat tumor-removal procedures. *改善对病人的护理,减少了需要重复肿瘤清除程序.
* keep health care costs down, given that treating fibroid tumors constitutes a significant health care expenditure, particularly if it involves major surgery such as hysterectomy, or requires multiple, repeat procedures of the traditionally used noninvasive therapies that include abdominal and laparoscopic tumor removal, or uterine artery embolization. *保持医疗成本下降,由于肌瘤治疗肿瘤构成重大医疗支出,尤其是如果它涉及重大手术,如子宫切除手术,或需要多次重复的程序,传统上使用的无创疗法,包括腹部及腹腔镜摘除肿瘤,或子宫动脉栓塞术.

Explains Mayo Clinic reproductive endocrinologist Elizabeth Stewart, M.D., the study’s lead author: “Up to one-third of women who undergo alternatives to hysterectomy to treat fibroids experience recurrence of fibroids, so demonstrating the durability of focused ultrasound is important.解释梅奥生殖内分泌学家伊丽莎白史,医学博士,研究的主要作者说: "多达三分之一的妇女曾接受替代子宫切除术治疗经验肌瘤复发肌瘤,以展现耐久性聚焦超声是重要的. Our study does this by examining rates of subsequent surgery for fibroid tumor symptoms and other key outcomes such as uterine shrinkage.我们研究这是否通过审查率,随后手术治疗肌瘤肿瘤的症状和其他重要成果,如子宫收缩. Finally, our study demonstrates that the more completely you treat the fibroids, the better the outcomes are.”最后,我们的研究表明,更全面地看待你的肌瘤,更好的成果. "

Evidence indicates that this novel technology, in the hands of experienced care-giving teams, is an effective, durable treatment for uterine fibroid tumors that safely produces sustained relief of symptoms, Dr. Stewart says.有证据表明,这种新型技术,在手的经历给予关爱队伍,是一个有效的,持久的治疗子宫肌瘤的肿瘤安全生产持续缓解症状,史博士说.

Magnetic resonance-guided focused ultrasound is a novel noninvasive technology for the outpatient treatment of fibroid uterine tumors.磁共振引导聚焦超声是一种新型的无创技术用于门诊治疗子宫肌瘤,子宫肿瘤. This treatment has been approved by the Food and Drug Administration (FDA) since 2004.这种治疗已通过美国食品和药物管理局( fda ) , 2004年以来. Mayo Clinic was among the first in the U.S to offer the procedure.梅奥最早在美提供程序.

Unlike other alternatives to hysterectomy, focused ultrasound does not depend on the insertion of devices, needles or catheters into the body.不像其他替代子宫切除术,超声聚焦,不取决于插入装置,针头或导管进入人体. High-energy sound waves are directed precisely through the abdominal wall to targeted fibroid tissues.高能声波都是针对正是通过腹壁针对性肌瘤组织. Thermal energy destroys the growths by coagulating the blood supply, while preserving healthy tissue.热能破坏速度由凝固的血液供应,同时维护健康组织. MRI images help physicians visualize the tissue volume and location and gauge the temperature of treated tissue.磁共振图像帮助医生形象化组织数量和位置,并搜集温度对待组织.

Uterine fibroid tumors - also called leiomyomas - are common noncancerous growths of the uterus.子宫纤维瘤又称为肌瘤-常见癌生长的子宫. When symptomatic, they can cause severe abdominal and leg pain, excessive menstrual bleeding and abdominal bloating.症状时,可造成严重的腹部和腿部疼痛,月经过多及出血,腹部膨胀. In the past, they have been treated by surgical removal of the uterus via hysterectomy, or through less invasive techniques such as abdominal and laparoscopic tumor removal, or uterine artery embolization.在过去,他们已治疗以手术切除子宫,经子宫,或通过微创技术,如腹部及腹腔镜摘除肿瘤,或子宫动脉栓塞术. However, those approaches are associated with elevated rates of tumor regrowth, and need for repeated treatments.然而,这些做法都与利率升高肿瘤复发,需要反复治疗. Thus these findings on noninvasive focused ultrasound treatment of fibroids are encouraging.因此,这些结果对创聚焦超声治疗子宫肌瘤是令人鼓舞的.
