Sponge on a string test to transform oesophageal cancer diagnosis

Barrett’s oesophagus is a condition that can lead to oesophageal cancer in a small number of people.

The Cytosponge test, developed by researchers at the University of Cambridge, is a small pill with a thread attached that the patient swallows, which expands into a small sponge when it reaches the stomach. This is quickly pulled back up the throat by a nurse, collecting cells from the oesophagus for analysis using a new laboratory marker called TFF3. It is found that this ‘sponge on a string’ pill test can identify ten times more people with Barrett’s oesophagus than the usual GP route, according to a new study
