Combining Hormones with External, Internal Radiation Helps High Risk Prostate Cancer Patients

30.12.2004


Prostate cancer patients with high risk cancers who are treated with both internal and external radiation and hormone treatment have a better chance of beating the disease than patients treated with radiation alone, according to a new study published in the January 1, 2005, issue of the International Journal of Radiation Oncology*Biology*Physics, the official journal of ASTRO, the American Society for Therapeutic Radiology and Oncology.



Since the late 1980s, doctors have been increasingly using internal radiation, also called radioactive seed implants or brachytherapy, to cure prostate cancer. For patients with higher risk prostate cancers – defined as having at least two of the following three: a high Gleason score, a high PSA score and/or an advanced stage – doctors have been adding hormone therapy and external beam radiation therapy to the treatment plan to try to increase survival rates. In this study, doctors studied nearly 200 men with high risk prostate cancer over eight years to see if adding external beam radiation and hormone therapy to brachytherapy did indeed increase disease-free survival rates.

Of the participating patients, 107 men were treated with external beam radiation therapy combined with seed implants. Another 69 patients received hormone therapy in addition to the seed implants and external beam radiation. After eight years, nearly 94 percent of the men who had hormone therapy in addition to the two types of radiation had no evidence of their prostate cancer, compared with 84 percent of the men who only had seed implants and external beam radiation therapy.


“This is an exciting study because it shows that adding hormone treatment and external beam radiation therapy to seed implants does indeed help men with high risk prostate cancer to live longer without the cancer returning,” said Gregory S. Merrick, M.D., lead author of the study and a radiation oncologist at Schiffler Cancer Center in Wheeling, W.Va.

ASTRO is the largest radiation oncology society in the world, with more than 8,000 members who specialize in treating patients with radiation therapies. As a leading organization in radiation oncology, biology and physics, the Society is dedicated to the advancement of the practice of radiation oncology by promoting excellence in patient care, providing opportunities for educational and professional development, promoting research and disseminating research results and representing radiation oncology in a rapidly evolving socioeconomic healthcare environment.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
