Key takeaways:
- A capsule-sponge take a look at might assist risk-stratify sufferers with Barrett’s esophagus.
- Sufferers categorized as low threat may very well be managed by capsule-sponge surveillance, reasonably than endoscopy.
A capsule-sponge take a look at might assist determine sufferers with Barrett’s esophagus who’re at low threat for dysplasia or esophageal most cancers and doubtlessly eradicate the necessity for repeat endoscopies, in response to analysis revealed in The Lancet.
BE is a identified threat issue for the event of dysplasia and esophageal most cancers. For that reason, sufferers identified with BE are monitored by means of common endoscopies, usually totaling 10 or extra throughout a affected person’s lifetime.
Knowledge derived from Tan WK, et al. Lancet. 2025;doi:10.1016/S0140-6736(25)01021-9.
Nonetheless, the chance of BE creating into most cancers is taken into account low, and endoscopy procedures are sometimes pricey and ugly for sufferers. Furthermore, the effectiveness of endoscopy in monitoring for most cancers is very variable, in response to examine co-author Rebecca C. Fitzgerald, MD, FRCP, professor of most cancers prevention and director of the Early Most cancers Institute at College of Cambridge.

“Endoscopy for Barrett’s surveillance will not be efficient — it’s usually carried out by nonspecialists, and up to date trials present that round 10% of instances of dysplasia and most cancers are missed,” Fitzgerald advised Healio. “Which means some sufferers re-present inside a 12 months of their surveillance process with a symptomatic most cancers that ought to have been identified earlier.”
Fitzgerald and colleagues developed a capsule-sponge machine as a attainable alternative for endoscopy for sure sufferers with BE. The know-how entails the affected person swallowing a capsule linked to a thread. The capsule dissolves and releases a sponge, and when the sponge is drawn again up, it collects cells from the esophagus. Biomarker testing is then used to risk-stratify sufferers for dysplasia or most cancers.
To judge whether or not this technique might assist determine high-risk sufferers and in addition be used as an alternative of endoscopy to watch low-risk sufferers, the researchers performed two potential, pragmatic implementation research at 13 hospitals within the U.Okay. Eligible individuals had been aged 18 years and older with nondysplastic BE who had been being monitored primarily based on U.Okay. pointers.
All sufferers underwent a capsule-sponge take a look at, adopted by endoscopy. These with out constructive capsule-sponge biomarkers had been categorized as low threat, if additionally they had no scientific threat elements, or average threat, if threat elements similar to age, intercourse and phase size had been current. Sufferers had been thought-about excessive threat if that they had abnormality in p53 or glandular atypia.
Analysis of high-grade dysplasia or most cancers by risk-group project served as the first consequence.
Outcomes confirmed that of 910 sufferers recruited between August 2020 and December 2024, 15% had been excessive threat, 31% had been average threat and 54% had been low threat.
Within the high-risk group, the constructive predictive worth for any dysplasia or worse was 37.7% (95% CI, 29.7%-46.4%). The very best threat for high-grade dysplasia or most cancers was seen in sufferers with each atypia and irregular p53 (RR = 135.8; 95% CI, 32.7-564) in contrast with the low-risk group.
The prevalence of high-grade dysplasia or most cancers within the low-risk group was 0.4% (95% CI, 0.1%-1.6%), whereas the damaging predictive worth for any dysplasia or most cancers was 97.8% (95% CI, 95.8%-98.8%).
“Our outcomes confirmed that within the low-risk group, the chance of high-grade dysplasia or most cancers was 0.4%, suggesting that these sufferers may very well be provided follow-up with the capsule-sponge take a look at,” Fitzgerald stated. “The high-risk group with a double biomarker constructive had an 85% threat of discovering dysplasia or most cancers. We name this tier 1, or extremely high-risk, and this implies these instances advantage a specialist endoscopy in a middle that would deal with the dysplasia or most cancers.”
Fitzgerald famous that since most sufferers with BE don’t develop most cancers, the capsule-sponge take a look at may very well be a dependable, patient-friendly various.
“Repeated endoscopy monitoring is worrying,” she stated. “A easy, non-endoscopic capsule-sponge take a look at achieved nearer to house is much less scary and may very well be much less operator-dependent. By lowering the burden of endoscopy in sufferers at very low threat, we will focus extra on the sufferers at increased threat.”
Within the U.Okay., this proof is presently being thought-about as a foundation for upcoming 2025 pointers, that are anticipated to be issued in Septmber 2025, with a requirement to proceed to audit the outcomes, Fitzgerald advised Healio.
“The GI neighborhood is realizing that we want a greater method to managing sufferers with Barrett’s esophagus,” she stated. “Exterior of the U.Okay., we hope that this can pave the way in which for non-endoscopic approaches to Barrett’s surveillance.”
