Radiation device allows for targeted breast radiation to control cancer

13.07.2010
A new study of breast cancer patients at the Moores UCSD Cancer Center and the Arizona Oncology Services shows that after almost two years, the radiation given with the Strut-Adjusted Volume Implant (SAVI™) controls the rate of cancer and may reduce the complications seen with alternate types of brachytherapy. This study also demonstrates the accuracy and flexibility of the device to maximize the dose to the target tissue and minimize the exposure of healthy surrounding tissue and organs.

"This is the first paper that documents the patients' status after almost two years," said Catheryn Yashar, MD, associate professor of radiation oncology at the UC San Diego School of Medicine and chief of breast and gynecological radiation services at the Moores UCSD Cancer Center. "After almost two years, the patients showed that the treatment was well-tolerated without experiencing significant side effects. To date, the control rate of cancer is also very promising."

SAVI, which consists of comfortable, flexible catheters through which radiation is given, provides customized radiation therapy and minimizes exposure to healthy tissue after a woman who has undergone a lumpectomy to remove a cancerous tumor. Radiation specialists sometimes decide to give women internal radiation – a process called brachytherapy – with the goal of giving concentrated doses of radiation to areas of concern while avoiding healthy tissue.

These findings reported in the International Journal of Radiation Oncology, Biology and Physics showed the results of 102 patients treated at a median follow-up time of 21 months. The researchers found that the SAVI appears to safely allow an increase in eligibility for patients to receive Accelerated Partial Breast Irradiation (APBI) over balloon brachytherapy or three-dimensional conformal radiation.

"This treatment allows us to provide internal radiation to the area without damaging the healthy tissue around the site, and minimizes radiation to a duration of only five days," explained Yashar. "The traditional whole breast treatment usually takes approximately six weeks."

Other authors of the clinical investigation include: Daniel Scanderbeg, Ph.D, Robert Kuske, MD, Anne Wallace, MD, Victor Zannis, MD, Sarah Blair, MD, Emily Grade, Virginia Swenson and Coral Quiet, MD.

The Moores UCSD Cancer Center is one of the nation's 40 National Cancer Institute-designated Comprehensive Cancer Centers, combining research, clinical care and community outreach to advance the prevention, treatment and cure of cancer.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
