Higher-risk people are shunning colon cancer screens

26.05.2008
It is difficult to make colon cancer screening effective, according to a follow-up study conducted by the Swedish medical university Karolinska Institutet of a screening programme from 1999. Many of the people who would probably have benefited most from the survey opted not to take part.

An acknowledged problem in public health surveys is that those who take part are generally more health conscious and healthier than those who do not. If this is also true of colon cancer screening, it means, at worst, that the people at greatest risk of developing the disease are not being screened, even though they would benefit most from the procedure.

A new study from Karolinska Institutet has confirmed these fears. Nine years ago, a team of researchers invited 2,000 people between the ages of 59 and 61 to take part in a colon cancer screening programme. Thirty-nine per cent of them accepted, but 61 per cent chose not to. A follow-up of these two groups has now shown that a larger percentage of the non-participants have since developed colon cancer or died, either from colon cancer or other diseases, compared with the participants.

“We do not think that the difference in incidences of cancer and death between the two groups is due to any effect the screening might have had, but believe it was down to the selection of people who took part,” says Johannes Blom, one of the researchers behind the study. “What we have here is the self-selection of more health conscious and healthier people , who perhaps don’t benefit as much from taking part.”

The team believes that those who opted out of the programme have less healthy lifestyles. This is supported by the findings that more of the non-participants have developed other forms of smoking-related cancer and that they run more than double the risk of dying from cardiovascular disease.

“If higher-risk people choose not to take part, public screening programmes will become very cost inefficient,” says Dr Blom. “One of the greatest challenges is therefore to encourage participation, so that the less motivated are also screened.”

On 1 January, the Stockholm County Council became the first health authority in Sweden to launch a screening programme for colon cancer.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
