Spectrometer helps to identify liver cancer risk
Jul 01 2012
Scientists working to develop a urine test to identify patients at risk of liver cancer in Africa received a huge boost following the donation by Waters Corporation of a mass spectrometer to laboratories in the Gambia.
The instrument will help to identify chemical markers of cancer and liver fibrosis, using samples from people with hepatitis B, a disease which can be treated if detected early. Researchers from Imperial College London are among those who will be using the technology as part of a five-year, 3 million-euro research project, PROLIFICA, that aims to reduce the incidence of liver cancer by treating chronic hepatitis B infection. This European Union-funded project also involves institutions from France, Gambia, Italy, Nigeria and Senegal. Hepatitis B is a viral infection transmitted through bodily fluids that attacks the liver. Despite being preventable with a vaccine, infection is endemic in sub-Saharan Africa and about one in four adults with chronic infection die of liver cancer or cirrhosis. Worldwide, an estimated 350 million people live with chronic infection and around 600,000 people die of its effects each year.
Preliminary studies have identified urinary biomarkers that might help doctors to detect cancer at an early stage when it is treatable, but more research is needed to validate these findings and make further progress towards developing a cheap and reliable diagnostic test.
The new mass spectrometer, the first installed in the region, was unveiled on 28 May at the Medical Research Council (MRC) laboratories in the Gambia, an event attended by representatives from the country’s ministry of health.
"We are very grateful for Waters’ kind donation,” said Professor Elaine Holmes, from the Department of Surgery and Cancer at Imperial, who travelled to the Gambia to train local researchers to use the mass spectrometer. “It opens up a whole host of new opportunities in research into infectious diseases, childhood illnesses, cancer and crucially in West Africa, into maternal and childhood nutrition."
Professor Simon Taylor-Robinson, from the Department of Medicine at Imperial, said: “The mass spectrometer will be enormously useful to our work towards developing a urinary dipstick for profiling patients with hepatitis B and preventing the progression to liver cancer. It will also enable us to leave a fantastic legacy in Africa, by building the capacity to undertake metabolic profiling studies locally.”
