Simple test could hold key to early diagnosis of cancers

10.06.2011
Cancers of the gut, stomach and pancreas could be detected much sooner with a simple urine test, research suggests.

Researchers at the University of Edinburgh have identified key proteins in the urine of patients with advanced cancers.

The findings could help the detection of these cancers in people who have not yet started to show symptoms of the disease.

This would enable patients to be diagnosed much earlier, leading to improved survival rates.

Only around 10 per cent of patients with these cancers – known as cancers of the upper gastrointestinal tract – are still alive five years after diagnosis.

This is because such cancers, which tend to be aggressive, are often diagnosed at an advanced stage.

Dr Holger Husi, of the University of Edinburgh's Tissue Injury and Repair Group, said: "The aim of this work is to enable these cancers to be diagnosed much earlier. This would help us to treat the cancer before it has a chance to spread. The majority of these cancers are currently diagnosed late where no surgery is possible due to its advanced stage. Earlier diagnosis would mean that curative surgery or chemotherapy would be possible for more patients."

The research, published in the journal Proteomics-Clinical Applications, compared urine samples from patients with upper gastrointestinal cancers with urine samples from people who were cancer-free.

Scientists analysed the samples to identify thousands of proteins. They then identified six particular proteins, which were present in 98 per cent of the cancer cases but absent in almost 90 per cent of samples from patients without cancer.

The researchers then narrowed molecules down to the two proteins – S100A6 and S1009 – most likely to appear in samples from patients with cancer but be absent from the other samples.

The scientists now intend to see whether people with early stage cancers, which have not yet been diagnosed, have the same levels of proteins present.

This would involve analysing samples from at least 1,000 volunteers and tracking the participants over a number of years to identify those who are then later diagnosed with upper gastrointestinal cancers.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
