The NHS will today (13 September) launch the world’s largest trial of a revolutionary new blood test that can detect more than 50 types of cancer before symptoms appear.
The first people to take part will have blood samples taken at mobile testing clinics in retail parks and other convenient community locations.
The Galleri(tm) test checks for the earliest signs of cancer in the blood and the NHS-Galleri trial, the first of its kind, aims to recruit 140,000 volunteers in eight areas of England to see how well the test works in the NHS.
The test is a simple blood test that research has shown is particularly effective at finding cancers that are typically difficult to identify early – such as head and neck, bowel, lung, pancreatic, and throat cancers.
It works by finding chemical changes in fragments of genetic code-cell-free DNA (cfDNA) that leak from tumours into the bloodstream. The NHS is already sending out letters inviting tens of thousands of people from different backgrounds and ethnicities aged between 50 and 77 to take part.
The NHS-Galleri trial is being run by The Cancer Research UK and King’s College London Cancer Prevention Trials Unit in partnership with the NHS and healthcare company, GRAIL, which has developed the Galleri test.
It is operating with the support of eight NHS Cancer Alliances across England that span Cheshire and Merseyside, Cumbria, Greater Manchester, the North East, West Midlands, East Midlands, East of England, Kent and Medway, and South East London. For the purposes of the trial, only people living in these areas will be invited.
NHS chief executive Amanda Pritchard said: “This quick and simple blood test could mark the beginning of a revolution in cancer detection and treatment here and around the world.
“By finding cancer before signs and symptoms even appear, we have the best chance of treating it and we can give people the best possible chance of survival.
“The NHS has a successful track record of leading the way on innovations in cancer diagnosis and treatment, from CAR-T therapy to COVID-friendly drugs.
“The Galleri blood test, if successful, could play a major part in achieving our NHS Long Term Plan ambition to catch three quarters of cancers at an early stage, when they are easier to treat.
“So if you are invited, please take part – you could be helping us to revolutionise cancer care and protect yourself.”
