Study reveals optimal interval for stomach cancer screening

16.07.2012
A new study has determined how often people should get screened for gastric or stomach cancer in high-risk regions of the world. Published early online in CANCER, a peer-reviewed journal of the American Cancer Society, the findings could help reduce deaths from gastric cancer, which is the second most common cause of cancer-related mortality.

Although the incidence of gastric cancer has decreased substantially in the western part of the world, the disease is still common in areas such as Eastern Asia, including Korea, Japan, and China.

Gastric cancer patients' prognosis strongly depends on the stage of the disease, or how advanced it is, at the time of diagnosis. In other words, early detection and treatment can save lives.

Gastric cancer screening is often done by upper endoscopy—using a tiny camera at the end of a long, flexible tube to look at the upper digestive system. To see how often this screening technique should be done to detect gastric cancer at an early stage, Il Ju Choi, MD, PhD, of the National Cancer Center in Korea, and his colleagues studied 2,485 patients who had been diagnosed with gastric cancer at their institution.

The researchers divided the patients into the following seven groups based on the interval between the endoscopy that detected gastric cancer and the endoscopy that preceded it: one year, two years, three years, four years, five years, more than five years, and never-screened. Currently, screening every two years is recommended in Korea for individuals who are aged 40 years or older.

The investigators found that gastric cancer stages were similar for screening intervals between one and three years; however, the cancer stage at diagnosis was significantly higher at screening intervals of four years or more.

"The optimal screening strategy appears to be every three years. Gastric cancers are likely to become more advanced before detection with screening intervals that are longer than three years, but screening more frequently than every three years does not appear to be more beneficial," said Dr. Choi. "The exception is if you have a family member with gastric cancer. In that case, you may need to undergo upper endoscopy screening more frequently than every three years," he added. Patients with a family history of gastric cancer were more likely to have a higher stage at diagnosis if they had a three-year interval rather than a one-year interval.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
