Most Barrett-related cancers arrive without surveillance

Design

Nationwide registry cohort

Population

8,914 Dutch patients treated for Barrett-related dysplasia or adenocarcinoma, 2008–2018

Primary outcome

Proportion with versus without prior surveillance endoscopy

Effect

90% de novo; stage ≥II in 70% (de novo) vs 11% (prior surveillance)

A nationwide Dutch cohort in Gut (21 September) identified 8,914 patients treated with curative intent for Barrett-related dysplasia or oesophageal adenocarcinoma between 2008 and 2018, and looked back for surveillance endoscopy in the preceding one to five years.

Ninety per cent had no prior surveillance; they presented de novo. They were far more likely to have stage II disease or worse (70% against 11% in those under surveillance). Even among patients suitable for organ-preserving endoscopic treatment, 65% presented de novo. Among those under surveillance, missed advanced neoplasia was uncommon at 11%.

Surveillance works for the patients in it; the problem is that most people with Barrett's oesophagus are never diagnosed. The study points towards better-targeted screening of high-risk groups rather than more intensive surveillance of known patients.

• Ninety per cent of Barrett-related neoplasia presented without prior surveillance
• Those under surveillance were diagnosed much earlier, mostly at endoscopically treatable stages
• Missed advanced neoplasia under surveillance was uncommon
• Consider screening in high-risk groups: chronic reflux, older men, central obesity, family history

Why it matters

It moves the debate from surveillance intervals to case-finding.

Don't overread it

Registry data from one country — it cannot say which screening strategy would close the gap.

The statistics, in plain English

The 90% figure (95% CI 89% to 91%) is very precise because the cohort is national. It describes where cases come from, not the effect of surveillance on survival.
