Abstract

Background

Efforts to reduce mortality from esophageal adenocarcinoma (EA) have focused on screening and surveillance of Barrett’s esophagus (BE).

Aims

We sought to determine the frequency of prior diagnosis of BE in patients with EA and to evaluate the impact of a prior BE diagnosis on mortality in EA patients.

Methods

This was a retrospective cohort study of patients diagnosed with EA in the VA during 2002–2016. We compared the distributions of EA stage and receipt of treatment between EA patients with and without a prior BE diagnosis and used Cox proportional hazards models to compare mortality risk (all-cause and cancer specific) unadjusted and adjusted for stage and treatment to assess their impact on any survival differences.

Results

Among 8564 EA patients, only 4.9% had a prior BE diagnosis. The proportion with prior BE diagnosis increased from 3.2% in EA patients diagnosed during 2005–2007 to 7.0% in those diagnosed during 2014–2016. EA patients with a prior BE diagnosis were more likely to have stage 1 disease and receive any treatment. A prior BE diagnosis was associated with lower all-cause mortality risk (hazard ratio [HR] unadjusted for stage, 0.69; 95% CI, 0.61–0.80), which was largely explained by the earlier stage of EA at the time of diagnosis (HR adjusted for stage, 0.87; 95% CI, 0.75–0.99). There was no evidence of lead time bias or length time bias.

Conclusions

Prior diagnosis of BE was associated with better survival, largely due to earlier EA stage at diagnosis.
