Oesophageal cancer is a significant health concern, and researchers at Cambridge have initiated a groundbreaking clinical trial to investigate the effectiveness of a ‘capsule sponge’ in preventing this type of cancer. The trial, named BEST4, is set to commence at Addenbrooke’s Hospital in Cambridge, with the aim of determining whether the capsule sponge could revolutionize cancer screening and potentially be incorporated into the NHS.

Tim Cowper, a 49-year-old resident of Cambridge, expressed his enthusiasm for being the first participant in the trial, emphasizing the potential impact it could have on future cancer screening methods. Cowper, who has experienced acid reflux since the age of 16, has undergone regular endoscopies to monitor his condition, describing the experience as unpleasant. In contrast, the capsule sponge test offers a more favorable and less invasive alternative.

The capsule sponge, also known as the ‘pill-on-a-thread,’ is designed to swiftly and simply detect Barrett’s oesophagus, a precursor to oesophageal cancer. Patients are required to swallow the capsule containing the sponge, which dissolves in the stomach and then expands to the size of a 50p coin. Subsequently, the sponge is retrieved using a string, enabling the collection of cells for laboratory analysis.

The initial phase of the trial will focus on individuals already diagnosed with Barrett’s oesophagus, assessing whether the capsule sponge test could replace the need for regular endoscopies. The subsequent phase, scheduled for the summer, aims to recruit 120,000 individuals over the age of 50 who are undergoing long-term treatment for heartburn.

If proven successful, the capsule sponge test could potentially evolve into a nationwide screening program within the NHS, akin to the utilization of mammograms for breast cancer screening. The trial, which has received joint funding from Cancer Research UK and the National Institute for Health and Care Research, builds upon extensive research led by Professor Rebecca Fitzgerald, a prominent figure at the University of Cambridge’s Early Cancer Institute.

Professor Fitzgerald highlighted the potential of the device to significantly reduce the annual number of deaths from oesophageal cancer, emphasizing that early detection is crucial in improving patient outcomes. She stressed that many individuals remain unaware of the issue until they encounter difficulties with swallowing, by which point it may be too late.

The commencement of the BEST4 trial marks a pivotal moment in the pursuit of more effective and accessible cancer screening methods, with the potential to positively impact the lives of numerous individuals at risk of oesophageal cancer.
