Abstract
OBJECTIVE: Patients with esophageal cancer may be reluctant to proceed with surgery due to high complication rates. This study aims to compare outcomes between eligible surgical candidates who proceeded with surgery versus those who refused surgery. METHODS: Characteristics and survival of patients with locally advanced (cT3N0M0, cT1-3N+M0) mid-/distal esophageal adenocarcinoma in the National Cancer Database (2006-2019) who either proceeded with or refused surgery after chemoradiotherapy were evaluated with logistic regression, Kaplan-Meier curves, and Cox proportional hazards methods. RESULTS: Of the 13,594 patients included in the analysis, 595 (4.4%) patients refused esophagectomy. Patients who refused surgery were older, had less distance to travel to their treatment facility, were more likely to have cN0 disease, and were more likely to be treated at a community rather than academic or integrated network program, but did not have significantly different comorbid disease distributions. On multivariable analysis, refusing surgery was independently associated with older age, uninsured, lower income, less distance to a hospital, and treatment in a community program versus an academic/research or integrated network program. Esophagectomy was associated with better survival (5-year survival 40.1% [39.2-41] vs 23.6% [19.9-27.9], P < .001) and was also independently associated with better survival in the Cox model (hazard rate, 0.78 [95% confidence interval, 0.7-0.87], P < .001). CONCLUSIONS: The results of this study can inform selected patients with resectable esophageal adenocarcinoma that their survival will be significantly diminished if surgery is not pursued. Many factors associated with refusing surgery are non-clinical and suggest that access to or support for care could influence patient decisions.
