Abstract

The impact of race/ethnicity (RE) or socioeconomic status (SES) on progression from Barrett's esophagus (BE) to esophageal cancer (EC) is not well established. We aimed to evaluate the association between demographic factors and SES on EC diagnosis in an ethnically diverse BE cohort. Patients aged 18-63 with incident BE diagnosed in October 2015-March 2020 were identified in the Optum Clinformatics DataMart Database. Patients were followed until the diagnosis of prevalent EC <1year or incident EC =1year from BE diagnosis, or until the end of their continuous enrollment period. Cox proportional hazards analysis was used to determine associations between demographics, SES factors, BE risk factors, and EC. Demographics of the 12,693 patients included mean age of BE diagnosis 53.0 (SD 8.5) years, 56.4% male, 78.3% White/10.0% Hispanic/6.4% Black/3.0% Asian. The median follow-up was 26.8 (IQR 19.0-42.0) months. In total, 75 patients (0.59%) were diagnosed with EC (46 [0.36%] prevalent EC; 29 [0.23%] incident EC), and 74 patients (0.58%) developed high-grade dysplasia (HGD) (46 [0.36%] prevalent HGD; 28 [0.22%] incident HGD). Adjusted HR (95% CI) for prevalent EC comparing household net worth =$150,000 vs. <$150,000 was 0.57 (0.33-0.98). Adjusted HRs (95% CI) for prevalent and incident EC comparing non-White vs. White patients were 0.93 (0.47-1.85) and 0.97 (0.21-3.47), respectively. In summary,a lower SES, captured by the household net worth, was associated with prevalent EC. There was no significant difference in prevalent or incident EC among White vs. non-White patients. EC progression in BE may be similar among racial/ethnic groups, but SES disparities may impact BE outcomes.
