PURPOSE: We sought to determine the impact of esophagectomy on survival in patients with adenocarcinoma of the esophagus cancer after chemoradiotherapy (CRT). METHODS: A database of esophageal cancer was queried for nonmetastatic patients with adenocarcinoma treated between 2000 and 2011 with CRT. Overall survival (OS) and recurrence-free survival (RFS) curves were calculated according to the Kaplan-Meier method and log-rank analysis. Multivariate analysis was performed by the Cox proportional hazard model. RESULTS: We identified 154 patients (60 without surgery; 94 with surgery) who were included in the analysis. The only differences between the 2 groups were more advanced disease stage, improved performance status, and younger age in the surgery group. Patients undergoing surgery had significantly higher survival. Median and 5-year OS for surgical patients were 4.1 years and 43.6 %, versus 1.9 years and 35.6 % for nonsurgical patients (p = 0.007). Multivariate analysis for OS and RFS revealed that factors associated with increased survival were surgical resection, tumor length < 5 cm, male gender, and lower stage. Age, tumor location, radiation dose/technique, and induction chemotherapy were not prognostic. There was a trend toward improved survival on univariate analysis (p = 0.10) and multivariate analysis (p = 0.063) for surgical patients compared to nonsurgical patients who were healthy enough for surgery before CRT (n = 38), and no difference in OS in nonsurgical patients healthy enough for surgery after CRT (n = 22). CONCLUSION: Esophagectomy after CRT is associated with improved survival in patients with adenocarcinoma after CRT. Trimodal therapy should continue to remain the standard of care for esophageal adenocarcinoma.
