Today’s Prostate Cancer Treatments More Aggressive, Successful

16.07.2004


In recent years, doctors have become more willing to treat prostate cancer more aggressively with radiation therapy, and as a result, more patients are being cured of their cancer, according to a new study published in the July 15, 2004, issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of ASTRO, the American Society for Therapeutic Radiology and Oncology.



A 1999 Patterns of Care survey reviewing the records of more than 550 patients from 58 institutions across the United States shows that in comparison to surveys from 1989 and 1994, radiation oncologists are using higher doses of external beam radiation therapy to treat both earlier stages and more aggressive forms of prostate cancer. In 1999, 45 percent of prostate cancer patients were treated with higher doses of radiation therapy compared to 3 percent in both 1989 and 1994.

In the study, researchers learned that the results of clinical trials have persuaded many radiation oncologists today to add androgen deprivation therapy to radiation therapy to treat more aggressive or well-established cancers. Further, there has been a significant increase in the use of CT-based treatment planning and conformal radiation therapy for treatment delivery.


“This is an important study because it looks at changing trends over many years in the use of radiation therapy for curing prostate cancer in the United States,” said Michael J. Zelefsky, M.D., lead author of the study and a radiation oncologist at Memorial Sloan-Kettering Cancer Center in New York. “After careful analysis, we have learned that in general, more radiation oncologists are applying the results of clinical trials, which have taught us to use higher dose levels of radiation and integrate hormone therapy in conjunction with radiation therapy to achieve more successful outcomes for prostate cancer patients. In short, the trends are demonstrating more precise delivery of high dose treatment.”

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
