Objective: This study was conducted to determine whether higher doses of intensity-modulated radiotherapy(IMRT) could improve the survival rate in patients of cervical esophageal squamous cell carcinoma (CESCC), and lead to more severe treatment-related toxicity. Methods: The clinical records of stage I–IVA CESCC patients treated with definitive chemoradiotherapy (CRT) using IMRT between January 2013 and June 2018 were retrospectively analyzed. The patients in the high-dose (HD) group received ≥60 Gy and those in the standard-dose group received <60 Gy. A propensity score matching (PSM) was applied to balance the confounding factors between both groups. The primary endpoint was over-survival (OS). progression-free survival (PFS), loco-regional control (LRC), and treatment-related toxicity were also evaluated. Results: A total of 136 patients with CESCC were included. Patients with N1–3 nodal and stages III–IVA of the disease (P < 0.05) were included in the HD group. The differences in the OS, PFS, and LRC between the two groups were not statistically significant (P = 0.350, 0.063, and 0.099, respectively). After PSM, significantly longer PFS and LRC were observed in the HD group. The difference in OS between the two groups was not statistically significant. There was no significant difference in the incidence of treatment-related toxicity between the two groups. Conclusions: The results of this PSM analysis suggested that higher doses may improve PFS and LRC for CESCC patients receiving CRT using OMRT, but do not demonstrate any statistically significant advantage in improving OS.
