After randomization, patient recruited will be arranged to receive UAE treatment. 100 patients will be recruited for UAE treatment

After randomization, patient recruited will be arranged to receive HIFU treatment. 100 patients will be recruited for HIFU treatment

The patient will be admitted into hospital for UAE. UAE was performed with patients under local anesthesia. Embosphere particles (BioSphere Medical) with a size of 500 - 700µm were used in all procedures. Embospheres were mixed with contrast material and saline and injected into each uterine artery until either parenchyma filling of the fibroids had stopped (target embolization) or the main uterine artery was blocked with stasis of contrast material (selective embolization). After the procedure, women were admitted to the gynecology ward for postprocedural care. All patients were advised to stay in the hospital for at least 1 night.

Treatment will be given to the patient in one or more sessions on an outpatient basis. The uterine fibroid will be identified and located with ultrasonography and ablated with HIFU. For lesion beyond 6 cm distance from skin, HIFU is given at a power of 1200-1500 watt for 1500 - 2000 times at each spot, for 50 milli-second each time, at an interval of 100 milli-second, at a spot distance of 1.5cm, a line distance of 1.5cm, and a plane distance of 1.0 -1.5cm; for lesion within 6 cm distance from skin, HIFU is given at a power of 1300±15% Watt for 40 times at each spot, for120 milli-second each time, at an interval of 100 milli-second, at a spot distance of 0.3cm, a line distance of 0.3cm, and a plane distance of 0.8cm.

HIFU

Simon CH Yu, MD, FRCR

This study aimed to evaluate the clinical effectiveness and adverse effects of Uterine Artery Embolization (UAE), High-Intensity-Focused-Ultrasound (HIFU) in treating patients with uterine fibroid.

The usual management for symptomatic uterine fibroid is surgery (myomectomy or hysterectomy), in the current study, uterine artery embolization (UAE) is a form of non-surgical and minimally invasive treatment, High-Intensity-Focused-Ultrasound (HIFU) is a form of non-invasive treatment that can be completed as an out-patient within hours. Embolization causes ischaemia and shrinkage of the fibroid and therefore symptomatic relieve. HIFU is a medical technology that has been used for cancer treatment. Energy is delivered from outside the body in a non-invasive manner to produce heat energy that causes necrosis and shrinkage of the uterine fibroid thereby relieves the symptoms due to the fibroid. It does not involve radiation. The clinical effectiveness of HIFU for uterine fibroid is unknown, however, based on the knowledge of the clinical effectiveness of HIFU on liver cancer and pancreatic cancer, there is reasonable ground to believe that HIFU is effective for uterine fibroid.

Uterine Artery Embolization(UAE) Versus High-Intensity-Focused-Ultrasound(HIFU) for Treatment of Uterine Fibroids

Randomized Controlled Trial of Uterine Artery Embolization (UAE) Versus High-Intensity-Focused-Ultrasound (HIFU) for Treatment of Patients With Uterine Fibroids

Technical success of treatment procedure and absence of symptoms of fibroid

Complications after treatment procedures will be recorded during each hospital admission and during each HIFU treatment session. Major adverse events will be reported. Complications that occur prior to a clinical visit will be documented and graded in each clinical visit at 1, 3, 6 and 12 month after treatment.

Assessed by 3 Dimensional ultrasonography (USG)

Contrast enhanced magnetic resonance imaging (MRI) is used to assess the degree of infarction, which is defined as non-perfused tissue on contrast MRI.

Assessed by contrast enhanced USG. Vascularity of the fibroid will be classified into six categories: 0%, \<25%, 25 to 50%, \>50 to 75%, \>75%, 100%.

MRgFUS treatment will take place in a MRI machine and powerful ultrasound waves go through the abdominal wall to destroy the fibroid or fibroids. No incision is made during this treatment and light sedation is required. There are certain fibroids that may not be treated with this technique and there is no treatment of normal uterine tissue.ough the abdominal wall to destroy the fibroid.

Focused ultrasound (MRgFUS)

UAE treatment takes place on a regular x-ray machine. A small incision is made where the leg meets the trunk and a small tube is used to use very small pellets to block off the blood supply to the entire uterus. Sedation is used. Most fibroids are treated with this technique and normal uterine tissue is also affected.

Uterine artery embolization (UAE)

Elizabeth A. Stewart, M.D.

The primary goal of this study is to compare the safety and effectiveness of two standard fibroid treatments: MRI guided ultrasound surgery (MRgFUS) and uterine artery embolization (UAE). Both treatments are approved by the Food and Drug Administration (FDA) for women who do not plan to become pregnant.

A second goal of this study is to better understand which symptoms bother women with fibroids the most. Understanding and addressing the symptoms of clinically-significant uterine fibroids is important in order to optimize treatment outcomes and control health care costs.

Women who are eligible to participate in the study, are randomized to one of two treatment arms (UAE or MRgFUS). Women in both arms will receive treatment but will not be able to choose which treatment she will receive.

A comprehensive assessment of symptoms-including experienced pain- will take place at baseline, 6 weeks, and at 6, 12, 24, and 36 months following treatment with UAE and MRgFUS.

Uterine fibroids affect up to 70 to 80% of women and about 30% of women are symptomatic. Over 200,000 hysterectomies are performed each year for uterine fibroids in the USA. The direct health care costs attributable to uterine fibroids exceed $2.1 billion annually. Fibroids are reported to cause a number of symptoms including heavy or prolonged menstrual bleeding, pelvic pressure, pain with menses and bowel and bladder dysfunction. However, fibroid symptomatology is incompletely understood. Understanding and addressing the myomas pain are important in optimizing treatment outcomes and controlling health care costs from a societal perspective. This study proposes to optimally characterize symptoms and symptom relief in women with leiomyomas severe enough to seek interventional therapy. Secondly we will characterize a variety of symptoms utilizing standardized instruments for other pelvic diseases and symptoms to optimize comparisons with other disease processes.

Clinical and scientific significance of the studies is high. We look to generate resources which can be used at a later time to assess the biologic and genetic variables affecting treatment outcome and to comprehensively assess the societal economic impact of uterine fibroids and their treatment with UAE and MRgFUS.

Participants will be in the study for up to 36 months following fibroid treatment.
