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.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
