NHS to bring ‘sponge-on-a-string’ cancer test to the high street

NHS to bring ‘sponge-on-a-string’ cancer test to the high street

People with persistent heartburn or acid reflux will be offered an innovative ‘sponge on a string’ test in high-street pharmacies for the first time, as part of a new NHS pilot to help prevent oesophageal cancer.

NHS England has today announced that dozens of pharmacies in England will offer new ‘heartburn health checks’ to test for Barrett’s oesophagus, which can be a precursor to oesophageal cancer.

The test involves patients swallowing a small pill on a thread, which expands into a penny-sized sponge when it reaches the stomach.

 

After a few minutes, it is safely pulled out to collect cells from the lining of the oesophagus, which are tested for pre-cancerous changes in the lab.

Delivered by a health professional in under 10 minutes, the test could help shift care from hospitals to the community as part of the 10-Year Health Plan, launched last week by the Government and NHS.

It is currently used in hospitals and Community Diagnostic Centres, helping reduce the need for invasive endoscopies and free up appointments for those at high risk of cancer – and the NHS will now pilot whether care could be made more convenient to help people get tested while they shop.

Professor Peter Johnson, NHS national cancer director said: “The NHS is catching more cancers earlier than ever before, and this new pilot brings a convenient test to where people shop, making it easier than ever for patients to check signs and symptoms that might be worrying them.

“For the majority of people with persistent reflux, these quick and easy heartburn health checks will provide peace of mind that you aren’t at increased risk of cancer, and for those who do find out they have Barret’s oesophagus, regular follow-up checks will be put in place so any further cell changes can be spotted early.”

Pharmacists will help spot patients who are regularly using over-the-counter medications to ease their heartburn or reflux symptoms but haven’t come forward to their GP, aiming to spot early changes in the lining of the oesophagus that otherwise may have been missed.

Partnering with Boots and gastrointestinal diagnostics company Cyted Health, from early next year around 1,500 people in London and the East Midlands will be offered the quick and easy test on-site in a pharmacy or be referred to a community-based clinic in their area.

Working closely with Heartburn Cancer UK, the pilot will be accompanied by a locally led public health awareness campaign on the potential signs and symptoms of oesophageal cancer to encourage more people to come forward.

The pilot will run for two years and the outcomes of an independent evaluation will inform decisions about any future roll-out.

Gastro-oesophageal reflux, also known as acid reflux, is a relatively common condition, affecting around two in every ten people.

Persistent symptoms can be a sign of the pre-cancerous Barrett’s oesophagus, and this simple test can help spot whether heartburn is a sign of a more serious problem.

If pre-cancerous cells are found, treatment can be offered to remove the cells through endoscopy or a procedure known as radiofrequency ablation.

Minister for public health and prevention Ashley Dalton said: “Last week, as part of our 10 Year Health Plan, we promised a Neighbourhood Health Service – convenient care nearer to where people live. Today’s announcement is a fantastic example of the lifesaving potential of healthcare on your high street.

“With more than 8,000 people diagnosed with late-stage oesophageal cancer each year, being able to spot the warning signs using a 10-minute test in a local pharmacy—before cancer has even taken hold—will be a game-changer.

“As part of our Plan for Change to tackle the biggest killers, this government is committed to back innovation and make our NHS fit for the future to drive up this country’s cancer survival rates.”

The project is one of 7 innovative pilots backed by a £15 million investment aimed to improve the early detection of cancer, as part of the NHS Cancer Programme’s Innovation Open Call.

This third annual funding round by the NHS Cancer Programme, supported by SBRI Healthcare and the Accelerated Access Collaborative helps to fast-track leading innovations that could transform cancer diagnosis and treatment for patients to the front line of the NHS.
