Background & Aims: Endoscopic therapy can improve long-term outcomes of patients with superficial esophageal adenocarcinoma (EAC), producing fewer complications than esophagectomy. However, there have been few population-based studies to compare long-term outcomes of patients who received these treatments. We used a large national cancer database to evaluate the outcomes of patients with superficial EAC who underwent endoscopic therapy or surgery. Methods: We used the Surveillance Epidemiology and End Results database to identify 1618 patients with Tis or T1 N0M0 EAC from 1998-2009. Patients were grouped on the basis of whether they received endoscopic therapy (n= 306) or surgery (n= 1312). Multivariate logistic regression was performed to identify factors associated with endoscopic therapy. We collected survival data through the end of 2009; overall survival and esophageal cancer-specific survival were compared after controlling for relevant covariates. Results: The use of endoscopic therapy increased progressively from 3% in 1998 to 29% in 2009. Factors associated with use of endoscopic therapy included age older than 65 years, diagnosis in 2006-2009 vs 1998-2001, and the absence of submucosal invasion. Overall survival after 5years was higher in the surgery group than in the endoscopic therapy group (70% vs 58%, respectively). After adjusting for patient and tumor factors, patients treated by endoscopy had similar overall survival times (hazard ratio, 1.21; 95% confidence interval, 0.92-1.58) and esophageal cancer-specific survival times (hazard ratio, 0.74; 95% confidence interval, 0.49-1.11). Conclusion: In a population-based analysis, the use of endoscopic therapy for superficial EAC tended to increase from 1998-2009. Long-term survival of patients with EAC did not appear to differ between those who received endoscopic therapy and those treated with surgery.
