Introduction. This study aimed to clarify the impact of the average relative dose intensity (RDI) of neoadjuvant chemotherapy with docetaxel, cisplatin, and 5-fluorouracil (DCF-NAC) for resectable locally advanced esophageal squamous cell carcinoma (ESCC). Materials and Methods. To identify the optimal RDI, recurrence-free survival (RFS) and cumulative incidence function for recurrence (CIF) were calculated in low and high RDI groups with any cut-off points. The optimal RDI was defined as the highest RDI administered with a significant increase in either RFS or CIF. The clinicopathological characteristics of the two groups divided by optimal RDI were investigated. The preoperative prognostic factors associated with RFS were confirmed by multivariable Cox proportional hazards model. Results. Among the 150 eligible patients treated with DCF-NAC from 2010 to 2020, 3-year RFS and CIF were 56.3% and 37.8% in 90 patients in the less than 80% RDI group (
