Background: Patients with localized EC eligible for resection at presentation should receive trimodality therapy (chemoradiation and surgery). However, surgical resection is not always performed in these patients because of poor performance status or reluctance in eligible patients to proceed with surgical resection after preoperative chemoradiation. Reports on the outcome of such patients are rare. Methods: Between 2002 and 2010, we identified 599 trimodality-eligible EC patients in our prospective database. All patients had extensive baseline staging, preoperative chemoradiation, and preoperative staging that included endoscopic biopsy and PET-CT. Of 599 patients, 32 patients declined surgery. Results: The median age was 70 years (range, 55-81), 29 patients (90.6%) were men and 30 (93.8%) were Caucasian. Majority had baseline stage II (44%) or III (38%) cancer. All 32 patients had an adenocarcinoma (moderate: 53.1%, poorly: 46.9%) and reached a clinical complete response (negative biopsy and PET in the physiologic range) post-chemoradiation. Four patients had salvage surgery and 3 are alive. Overall, 22 patients remain alive at a median follow up of 33.1 months (95% CI, 28.1-38.1). 3-year overall survival (OS) and relapse-free survival (RFS) were 65.1±10.4% and 37.5±10.3%. Median OS and RFS were 54.2 months (95% CI, 25.7-82.7), 30.4 months (95% CI, 16.3-44.5). Conclusions: Although the outcome of patients with EC who decline surgical resection after chemoradiation is reasonable, the lack of a validated approach to esophageal preservation dictates that trimodality therapy remains the standard of care in patients with potentially resectable EC.
