Abstract

Background: The purpose of this study was to present our analysis of outcomes, prognostic factors, and treatment for cervical esophageal carcinoma using the Surveillance, Epidemiology, and End Results (SEER) database.

Methods: A query of the SEER database from 1998 to 2008 was performed for patients with nonmetastatic adenocarcinoma or squamous cell carcinoma (SCC) of the cervical esophagus. Disease-specific survival (DSS) rates were calculated using Kaplan-Meier method, and predictive factors were analyzed by Cox proportional hazards regression.

Results: We identified 362 patients; 92% of the patients had SCC, 16% received no definitive therapy, 5% received surgery, 71% received radiation therapy (RT), and 8% received both. Chemotherapy data were not available. Median DSS was 49 months for adenocarcinoma and 15 months for SCC. On multivariate analysis, histology (p = .02), RT (p < .001), and surgery plus RT (p < .001) were associated with DSS.

Conclusion: Survival in patients with cervical esophageal carcinoma remains poor. Further studies should define the use of RT, surgery, and chemotherapy.

Keywords: adenocarcinoma; cervical esophagus; esophagectomy; radiotherapy; squamous cell carcinoma.
