Introduction
Endoscopic eradication therapy (EET) is the preferred treatment for Barrett’s esophagus (BE)-related neoplasia patients. However, the impact of EET on critical outcomes, outside of clinical trials and registry data, remains scarcely studied. We aimed to assess real-world practice patterns and clinical outcomes among BE patients undergoing EET.
Methods
TriNetX is a large research network comprising linked inpatient and outpatient electronic-health record-derived data from over 80,000,000 patients. Patients with a diagnosis of BE from 2015 to 2020 were identified and included if they underwent EET during the study period. The primary outcome was the progression to EAC after index EET. Secondary outcomes included rate of esophagectomy, and all-cause mortality. All outcomes were stratified by baseline histology. The incidence of EAC and all-cause mortality were reported in person-years and adjusted for age and sex.
Results
A total of 4114 patients were analyzed. Distribution of baseline histology was as follows: NDBE (11.8%), LGD (21.4%), HGD (26.4%), EAC (20.8%), and unspecified (19.6%). The total incidence of EAC after index EET was 6.01 per 1000 person-years (PY) for the entire cohort with the highest rate in HGD patients (12.9/1000 PY). The incidence of all-cause mortality was 13.23 per 1000 PY with the highest rates in EAC patients (25.1 per 1000 PY). Rates of esophagectomy were < 1% for all grades of dysplasia.
Conclusion
The results of this study provide “real-world” data on critical outcomes for BE patients undergoing EET, demonstrating a low risk of incident EAC, all-cause mortality, and need for esophagectomy.
