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 quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
