Researchers start new clinical trial to examine ways to improve treatment of uterine fibroids

30.05.2006


Uterine fibroids affect the health and quality of life of more than six million women in the US every year



Researchers at the University of Pennsylvania School of Medicine are working on ways to improve the results of a non-surgical method to treat fibroids. They are examining the overall effectiveness of different agents used to destroy uterine fibroids - a discovery that could lead to more answers about the durability of a procedure called Uterine Fibroid Embolization (UFE). It’s already been established throughout the medical community that, after a decade, UFE works to relieve the symptoms of fibroids. Now, in this new study, investigators want to learn how to optimize the procedure, by running a comparison of materials used during it.

"We already know that UFE has an 85-90% success rate, offering less complications and a shorter recovery time than surgical options," Richard Shlansky-Goldberg, MD, Interventional Radiologist at Penn and Principal Investigator of this study, explains, "So in 2006, the question becomes, now that we know the procedure is effective and durable, ’Which product would be better?’"


Uterine fibroids are benign (non-cancerous) tumors of the uterus that affect an estimated 20-40% of women, and for many, cause symptoms disrupting the quality of their lives. Uterine Fibroids affect more than six million women in the U.S. each year. The exact reason uterine fibroids (the most common type of abnormal growth in the uterus) develop is unknown, but medical researchers have associated the condition with genetics and hormones. If left untreated, uterine fibroids can cause infertility.

The treatment for uterine fibroids depends upon the size and location of the fibroids and the severity of symptoms. Uterine fibroid embolization (UFE), also known as uterine artery embolization (UAE), is a minimally invasive alternative to a hysterectomy and is a proven way to treat fibroids and relieve its symptoms of heavy bleeding, pressure, pain, and excessive urination.

Interventional radiologists don’t actually remove the fibroids during the UFE procedure. They shut them down and gradually shrink them, by blocking the blood supply to the fibroids. They do this by using a catheter to inject embolic agents (tiny plastic or sponge-like particles) into the artery, to "dam up" the blood flow to the fibroids.

During this trial at Penn, several researchers will utilize two different embolic agents, comparing the outcomes in patients. 24 hours after each procedure, they will conduct an MRI to see how much fibroid tissue is destroyed. They’ll look again, when the patient leaves the hospital. Shlansky-Goldberg adds, "We hope to answer two questions. One - In looking at the different outcomes of each particle, does one do a more effective job of eliminating fibroids? And two -- What does the uterus look like immediately after the UFE procedure and then later, after three months?"

This is a randomized, single-center study comparing Contour SE Microspheres to Embosphere Microspheres for treating symptomatic uterine fibroids with UFE. The head-to-head study at Penn, funded by Boston Scientific, will involve 60 patients. Penn is still enrolling patients in the study.

The clinical trial is expected to last about nine months.

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
