ERSPC is the world's largest prostate cancer screening study and provides robust, independently audited evidence, for the first time, of the effect of screening on prostate cancer mortality.
The study commenced in the early 1990s involving eight countries – Belgium, Finland, France, Italy, Netherlands, Spain, Sweden and Switzerland - with an overall follow-up of up to 12 years. Participants totalled 182,000 but then narrowed down to 162,000 men in seven countries, aged 55-69; only those who had not been screened could take part. The findings are being unveiled at the 24th Annual Congress of the European Association of Urology (EAU) in Stockholm, Sweden (17 - 21 March 2009).
By initially screening men 55 to 69 years with the PSA marker and offering regular follow up, this led to an increase in early detection. Deaths due to metastasized disease were then reduced. Exact data showed that on average for every 1,408 men screened, 48 had cancer diagnosed and received treatment, resulting in saving one life. Screening took place on average every four years with a mean follow-up over nine years. The cut-off value was a PSA level of 3.0 ng/ml or more. Men with this reading were then offered a biopsy.
Prof Fritz Schröder, international coordinator of the ERSPC study explained: "The study shows that PSA screening delivers a 20% reduction in mortality from prostate cancer. This provides decision makers on screening policies with important new data on the effectiveness of PSA testing in preventing deaths."
"However, the ERSPC is also near to completing additional studies on quality of life and cost-effectiveness and these must be assessed before making a decision about the appropriateness of a national prostate screening policy."
Worldwide, prostate cancer is the second leading cause of cancer death. Separate ERSPC findings already confirm that approximately 30% of detected cancers actually have non-aggressive features and are 'indolent' or slow growing. This overdiagnosis is an unavoidable effect from all cancer screening procedures. With prostate cancer, a new, more conservative form of monitoring, 'Active Surveillance', might be an important method to help avoid early invasive treatment.

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
