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: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
