Long-term hormone use helps prostate cancer patients live longer

02.11.2005


Doctors in Canada have discovered that treating high-risk prostate cancer patients with radiation therapy and adding hormone therapy for more than one year allows patients to live longer, have better control of their prostate specific antigen levels and lowers the rate of death specifically from prostate cancer, according to a study published in the November 1, 2005, issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of ASTRO.



A total of 307 patients with a PSA level greater than 20 were split into two groups, both with a similar demographic of age, Gleason score and tumor stage. The first group had 151 patients receiving hormone therapy for less than 12 months (short term) and the second set had 156 patients receiving hormone therapy for more than 12 months (long term). Both groups were treated with hormone therapy in conjunction with external beam radiation therapy.

In the long-term hormone therapy group, 62.5 percent of patients showed a greater control over their PSA level, compared with 37 percent in the short-term group. The five-year overall survival rate was 87.5 percent for the long-term group and 75 percent in the short-term group. The chance of dying of prostate cancer was reduced from 18 percent to 6 percent in the long-term group.


"Other randomized trials have shown the benefit of combining radiation and hormone therapy in the treatment of prostate cancer. However, some of those reports appear to be restricted to patients with a high Gleason score," said Eric Berthelet, M.D., lead author of the study and a radiation oncologist at the BC Cancer Agency in Victoria, British Columbia, Canada. "This study proves that long-term hormone therapy used in consort with radiation therapy improves survival rates for high-risk patients, regardless of their Gleason score or tumor stage."

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,...
