Study finds liver cancer increasing in low risk countries, decreasing in high risk countries

07.10.2011
A new study finds liver cancer incidence rates continue to increase in some low-risk parts of the world such as North America, and are decreasing in some of the highest risk countries of Asia.

Despite this, the incidence rates in Asian countries remain twice as high as those in Africa and more than four times as high as rates in North America. The study will be published in an upcoming issue of Cancer Epidemiology Biomarkers and Prevention and appears early online.

Using data from the International Agency for Research on Cancer, American Cancer Society epidemiologists Melissa M. Center, MPH and Ahmedin Jemal, PhD examined recent trends in liver cancer incidence rates from 1993 to 2002 for 32 cancer registries worldwide. They also examined the male to female rate ratios for these and four additional registries, based on the 1998 incidence data.

They found liver cancer incidence rates for both men and women increased from 1993 to 2002 for eight of the 32 cancer registries considered in the analysis. Increases were largely confined to economically developed countries of Western Europe, North America, and Oceania and may be partly due to increased chronic HCV infection as a result of unscreened blood transfusions and contaminated needles used for medical purposes and with widespread intravenous drug use in previous decades. In contrast, rates decreased in both men and women in five registries including three in Asia. Despite this, incidence rates in Asian countries remain three to four times higher than those in low-risk areas with increasing rates. Male to female rate ratios varied from 0.9 in sub-Saharan African and South American registries to 5.0 (five men for every woman diagnosed) in France and Egypt.

The authors conclude that liver cancer incidence rates continue to increase in some low-risk parts of the world, while they are now decreasing in some of the highest risk countries in Asia. Additional studies looking at causation are needed, they say, to further elucidate factors contributing to these divergent liver cancer incidence trends worldwide.

"We hope our description of international liver cancer incidence trends may stimulate studies to further illustrate etiologic factors associated with these divergent liver cancer incidence trends worldwide," said Ms. Center.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
