Abstract

Background: Re-irradiation (re-RT) has the active effect of relieving clinical symptoms and prolonging the survival of patients with recurrent esophageal squamous cell carcinoma (ESCC). However, the optimal re-RT dose is still uncertain. Here, we analyzed the prognostic factors associated with survival and explored the  re-RT dose for patients with recurrent ESCC following definitive chemoradiotherapy. Patients and methods: The data of 30 patients with recurrent ESCC who were retreated between 2018 and 2021 were analyzed. All patients received a radiation dose > 45 Gy. The median time to recurrence after primary radiotherapy was over 16 months (76.67%). All patients had in-field recurrence in the esophagus. Recurrence within the local and recurrence in both the local site and regional nodes). All patients received VMAT re-RT with a median dose of 45 Gy-50.4 Gy. Chemotherapy was sequentially and survival curves were constructed according to the Kaplan-Meier method and were compared by log-rank tests. Results: Dysphagia relief after re-RT was achieved in 23 patients rates 76.7%. The median survival time (MST) of all patients was 19,85 ± 0,59 months. Severe complications were observed in 0 patients. Conclusion: Our results demonstrated that patients with recurrent ESCC following definitive radiotherapy had unfavorable OS. Re-RT could be considered a feasible and effective treatment modality. A re-RT dose > 45 Gy could improve the survival outcomes, and a dose > 50.4 Gy should be administered with caution due to the risk of severe complications.
