Abstract

Background: Experience with neoadjuvant chemoradiation (CXRT) has raised questions regarding the additional benefit of surgery after locally advanced esophageal adenocarcinoma patients achieve a clinical response to CXRT. We sought to quantify the value of surgery by comparing the overall (OS) and disease-free survival (DFS) of trimodality-eligible patients treated with definitive CXRT vs. CXRT followed by esophagectomy. Methods: We identified 143 clinical stage III esophageal adenocarcinoma patients that were eligible for trimodality therapy. All patients successfully completed neoadjuvant CXRT and were considered appropriate candidates for resection. Patients that were medically inoperable were excluded. Cox regression models were used to identify significant predictors of survival. Results: Among the 143 patients eligible for surgery after completing CXRT, 114 underwent resection and 29 did not. Poorly differentiated tumors (HR = 2.041, 95% CI = 1.235-3.373) and surgical resection (HR = 0.504, 95% CI = 0.283-0.899) were the only independent predictors of OS. Patients treated with surgery had a 50 and 54 % risk reduction in overall and cancer-specific mortality, respectively. Median OS (41.2 vs. 20.3 months, p = 0.012) and DFS (21.5 vs. 11.4 months, p = 0.007) were significantly improved with the addition of surgery compared to definitive CXRT. Conclusions: Surgery provides a significant survival benefit to trimodality-eligible esophageal adenocarcinoma patients with locally advanced disease.
