Abstract To identify efficacy and prognosis of radiotherapy (RT) for cervical lymph node recurrence (CLNR) in thoracic esophageal squamous cell carcinoma (TESCC) after curative resection. The clinical data from 65 patients were retrospectively analyzed. The Kaplan–Meier method was employed to analyze the survival of patients. The Cox proportional hazards model was then exploited for multivariate analysis. The median overall survival (OS) was 20 months; one-year, two-year, three-year and five-year survival rates were 68.3%, 47.3%, 33.4% and 10.6%. The median progression-free survival (PFS) was 14 months. Univariate analysis indicated that time from surgery to recurrence, number of recurrent lymph nodes and dose of RT were significant prognostic factors, whereas multivariate analysis showed that number of recurrent lymph nodes and radiation dose were independent factors. RT was an effective salvage treatment for patients with CLNR after surgery. Those patients who showed single lymph node recurrence and who were exposed to ≥60 Gy of RT experienced a favorable prognosis.
