Focused ultrasound relieves fibroid symptoms in womenMay 29, 2007OAK BROOK, Ill. -- A noninvasive ultrasound procedure effectively shrinks uterine fibroids and significantly relieves fibroid-related symptoms in women, according to the results of a multicenter clinical trial reported in the June issue of the journal Radiology. Magnetic resonance-guided, focused ultrasound surgery (MRgFUS) allows radiologists to precisely target fibroids without harming healthy surrounding tissue. "This treatment immediately stops blood flow in the treated fibroid tissue, which results in a significant, sustained decrease in symptoms for up to 12 months," said the study's lead author, Fiona M. Fennessy, M.D., Ph.D., assistant professor of radiology at Harvard Medical School and staff radiologist at Brigham and Women's Hospital in Boston. Uterine fibroids are benign growths of the muscle inside the uterus. According to the National Institutes of Health, at least 25 percent of women in the United States age 25 to 50 suffer from symptomatic uterine fibroids. Fibroid symptoms can include excessive menstrual bleeding, enlarged uterine size, frequent urination, pelvic pressure or pain and infertility.
According to the National Women's Health Information Center, fibroids are the primary reason for surgical removal of the uterus, accounting for approximately one-third of hysterectomies performed annually in the U.S. MRgFUS represents a noninvasive, outpatient alternative to hysterectomy. "This treatment is ideal for older women who have completed their families and have a single or limited number of fibroids," said co-author Clare M. Tempany, M.D., professor of radiology at Harvard Medical School and director of Clinical Focused Ultrasound at Brigham and Women's Hospital. The researchers studied 160 women with symptomatic fibroids. The women received pre-treatment MR imaging to identify and define the target fibroids. Radiologists then used MRgFUS to locate and treat the targeted fibroids while monitoring temperature changes in tissue. Ninety-six patients were treated under the original study protocol (A), and 64 patients were treated under an optimized protocol (B). Protocol A allowed a maximum treatment time of 120 minutes and a maximum fibroid treatment volume of 100ccs (roughly six centimeters (cm) in diameter), or up to 33 percent of total fibroid volume. Protocol B allowed a maximum treatment time of 180 minutes and maximum fibroid treatment volume of 150ccs (about seven cm in diameter), or up to 33 percent of total volume in subserosal fibroids (those on the outer wall of the uterus) and 50 percent of volume in non-subserosal fibroids. "Through this study, we've learned that MRgFUS can be optimized with newer protocols to have even better results than previously thought possible," Dr. Tempany said. The findings showed significant symptom relief at three months and sustained relief at one year. Women treated with the optimized protocol reported greater symptom relief and quality of life improvement than those treated with the original protocol. No serious adverse effects were reported. "We have shown that treating fibroids with an optimized, less restrictive protocol allows for treatment of a greater fibroid volume, which results in even greater symptomatic relief at clinical follow-up," Dr. Fennessy said.

Fibroids common, but women have options Small fibroids located just beneath the lining of the uterus (submucosal) are more likely to move to the endometrial cavity after uterine artery embolization (UAE) but usually don't cause major complications, according to a new study. Treatment advances for fibroids, menopause Women with fibroids and endometriosis facing the possibility of hysterectomy may now choose less invasive treatment options to preserve fertility, according to Yale professor Aydin Arici, M.D., who will direct a scientific session exploring these alternatives at the American College of Obstetricians and Gynecologists (ACOG) Annual Clinical Meeting May 3-7 in New Orleans, Louisiana. Major surgery no longer needed for the removal of uterine fibroids The treatment of uterine fibroids with 3T MR-guided focused ultrasound (MRgFUS) is safe, non-invasive and effective, according to a recent study conducted by researchers at Weill Cornell Medical College in New York, NY. Minimally invasive fibroid treatment fares well in multicenter trial A new multicenter trial found that uterine artery embolization (UAE) is a good alternative to hysterectomy in women with symptomatic fibroids. The findings of the Embolisation versus Hysterectomy (EMMY) Trial appear in the March issue of the journal Radiology. Mayo Clinic study finds focused ultrasound treatment of uterine fibroids long term symptom relief A noninvasive, outpatient treatment for noncancerous uterine tumors provides sustained relief from symptoms, according to a new Mayo Clinic led collaborative study. Enhanced MR-guided focused ultrasound guidelines demonstrate improved efficacy and durability Data released today show that MR-guided focused ultrasound (MRgFUS) is a more effective option for a broader population of uterine fibroid sufferers.
