Blood Transfusions From Precancerous Blood Donors Do Not Increase Risk Of Cancer

18.05.2007
There is no evidence to suggest that blood transfusions from donors with undiagnosed cancer are associated with increased risk of cancer among recipients. The findings are reported in an Article in this week’s edition of The Lancet.

Professor Olof Nyrén and Gustaf Edgren, Karolinska Institutet, Stockholm, Sweden together with Professor Mads Melbye and Dr Henrik Hjalgrim from Statens Serum Institut, Copenhagen, Denmark organised a binational project to study the cancer incidence among patients who received blood from donors deemed to have a subclinical cancer at the time of donation.

Using data from all computerised blood bank registers in Sweden and Denmark that were gathered between 1968 and 2002, the researchers identified 1.13 million blood donors and 1.31 million transfusion recipients. Out of the more than 350,000 recipients eligible for the analysis, just over 12,000 (3%) were exposed to blood products from precancerous donors. The recipients were followed for as long as 34 years.

The authors say: “Continuous attention to transfusion safety has reduced the risk of transfusion-transmitted disease to a current record low. However, although most infectious complications have been relatively easy to identify, possible transmission of chronic diseases with unknown causes and long induction or latency periods has been far more difficult to address.”

They conclude: “Our data provide no evidence that blood transfusions from precancerous blood donors are associated with increased risk of cancer among recipients compared with transfusions from non-cancerous donors.”

In an accompanying Comment, Dr Garth Utter, Department of Surgery, University of California, Davis, Sacramento, California, USA, says: “Blood is an immensely complex and biologically active substance. Although the potential for standard allogeneic blood transfusion to save lives is incontrovertible, our understanding of the full consequences of transfusion is rudimentary.”

He adds: “With their thoughtful analysis of a large and relatively complete dataset, Edgren and colleagues have taken an important stride forward in evaluating one of these potential long-term risks of blood transfusion.”

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...

Computer-assisted methods aid Heidelberg physicists in reproducing experiment with ultracold atoms

Two researchers at Heidelberg University have developed a model system that enables a better understanding of the processes in a quantum-physical experiment...

Im Focus: Glacier bacteria’s contribution to carbon cycling

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.

A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
