Introduction Local recurrence (LR) is clinical challenge in the treatment of esophageal squamous cell carcinoma (ESCC). The current study aimed to determine the optimal re-irradiation dose for local recurrent esophageal squamous cell carcinoma (LRESCC) following radical (chemo) radiotherapy. Methods We retrospectively analyzed 125 patients with LRESCC after receiving initial radiotherapy. For radiotherapy treatment, 58 patients were assigned to low-dose (LD) group (50–54 Gy) and 67 were assigned to the high-dose (HD) group (55–60 Gy). The response rate (complete + partial response), 1-, 2- and 3-year survival rate, and toxicity were recorded. We then analyzed the impact of different radiotherapy doses and combination chemotherapy on the survival of patients with LRESCC. Results After re-irradiation, the 1-, 2- and 3-year survival rates in the LD and HD groups were 48.3%, 24.1% and 10.3% and 61.2%, 34.3% and 19.4% in the HD group, respectively, and the difference in overall survival rate between the two groups were significant (P P Conclusion Higher re-irradiation dose (55–60 Gy) can improve the long-term survival of patients with LRESCC after radiotherapy, with tolerable toxicity.
