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.”

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.

The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...

A research team from the University of Zurich has developed a new drone that can retract its propeller arms in flight and make itself small to fit through narrow gaps and holes. This is particularly useful when searching for victims of natural disasters.

Inspecting a damaged building after an earthquake or during a fire is exactly the kind of job that human rescuers would like drones to do for them. A flying...
