Annual prostate cancer screening test appears to save lives

20.10.2005


Men who have a yearly blood test to examine their prostate specific antigen levels are nearly three times less likely to die from prostate cancer than those who don’t have annual screenings, according to a study presented October 19, 2005, at the American Society for Therapeutic Radiology and Oncology’s 47th Annual Meeting in Denver.


The study shows that over an estimated 10-year period, men who have an annual prostate specific antigen (PSA) test will have a 3.6 percent chance of dying from the disease, compared to 11.3 percent in the general population. Patients who have the test are more likely to be diagnosed with prostate cancer that is curable in the vast majority of cases, as opposed to aggressive cancers that are less likely to be curable.

"The PSA blood test is the best simple screening test available for prostate cancer that picks up prostate cancer earlier, while it’s still curable," said Jason Efstathiou, M.D., lead author of the study and a resident at the Harvard Radiation Oncology Program in Boston.

A PSA test is a blood test that measures the level of prostate specific antigen, a protein produced by the prostate. Increased levels of PSA may be a sign of prostate cancer.



The study took place between 1988 and 2002 and involved 1,492 men who were treated for prostate cancer by the surgical removal of their prostate and whose cancer came back. Among this group, 841 men had yearly PSA tests before their cancer diagnosis, while 611 men were diagnosed by other methods. There are large, randomized trials currently going in both the U.S. and Europe that will further confirm the impact of PSA screening tests among prostate cancer patients by 2008.

Im Focus: Neutron star merger directly observed for the first time

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...

Im Focus: Breaking: the first light from two neutron stars merging

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....

Im Focus: Smart sensors for efficient processes

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...
