Abstract

Purpose

To evaluate the survival benefit of combining radiotherapy with surgery in locally advanced esophageal squamous cell carcinoma (ESCC) patients aged over 65.

Methods

Using the SEER database, we selected patients age ≥ 65 years that were diagnosed as locally advanced ESCC during 2004–2013. Cancer-specific survival (CSS) was examined using the Kaplan–Meier analysis and compared by the log-rank test. Univariable and multivariable Cox proportional hazard models were established to identify possible prognostic factors.

Results

A total of 972 cases were included in the study. For surgical patients aged 65–79 years, 74 patients (32.9%) were treated by surgery alone and 122 patients (54.2%) had received additional neoadjuvant radiotherapy (NRT). NRT + surgery was associated with improved CSS comparing with surgery alone (HR, 0.58; 95%CI, 0.39 to 0.85; P = 0.005). In subgroup analysis, NRT was associated with improved CSS for patients aged 65–74 years (2-year CSS 56.6% versus 39.6%, P = 0.026). No significant differences of progonosis was observed for different treatment groups in 75–79 years patients (P = 0.972).

Conclusions

In this SEER-based study, the addition of neoadjuvant radiotherapy before surgery was associated with improved CSS for locally advanced ESCC patients aged 65 to 74 years.
