Stanford trial studies vastly shorter radiation time for breast cancer treatment

21.11.2002


A new radiation approach being tested at Stanford University Medical Center could shorten the overall treatment time for women with breast cancer. Participants will receive a single dose of radiation at the time of surgery rather than the usual six-week course of radiation therapy. The clinical trial is now recruiting patients.



"The trial should tell us whether this accelerated form of radiotherapy is safe, feasible and effective in controlling cancer recurrence in the breast for certain women who have a lumpectomy," said Frederick Dirbas, MD, assistant professor of surgical oncology at the Stanford School of Medicine and leader of the trial.

Women with a breast tumor often have a lumpectomy, surgery in which the doctor removes only the cancerous region, leaving the rest of the breast intact. The patient then receives a dose of radiation to the entire breast each weekday for about the next six weeks to minimize the risk of cancer returning.


"The fact that current radiation treatments occur every day for several weeks makes it an issue for women," Dirbas said, adding that the schedule can be inconvenient for women who work, care for young children or live far from the treatment site. He said the idea behind this prolonged schedule was that women would experience fewer side effects if the total radiation dose was broken into smaller increments.

In recent years, however, doctors in the United States and Europe have begun looking at approaches to shorten the overall treatment time while still fending off cancer. In one Italian trial with more than 100 participants, patients received a single large dose of radiation at the same time as the surgery. Two years after the initial surgery, the treatment appears to be safe and effective.

Based on this success, Dirbas and Donald Goffinet, MD, professor of radiation oncology, are replicating the Italian trial - the first U.S. trial of this technique. They hope to recruit 50 women who are older than 40, have a single breast tumor that is smaller than 2.5 centimeters and have a low likelihood of tumors elsewhere in the breast.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
