Abstract

Purpose: To evaluate the efficacy and toxicity of definitive concurrent chemoradiotherapy (CCRT) with docetaxel plus cisplatin (DP regimen) versus 5-fluorouracil plus cisplatin (PF regimen) in patients with oesophageal squamous cell carcinoma (ESCC). Patients and Methods: In this phase II randomized controlled trial, eighty-six patients with clinical stage II - IVa ESCC were randomized to receive radiotherapy concurrently with two cycles of the PF or DP regimen at 3-week intervals. The primary endpoint was overall survival (OS). The secondary end points included the overall response rate (ORR), progression-free survival (PFS) and treatment-related toxicities. Results: The ORRs were 84.4% in the DP group and 87.3% in the PF group (P = 0.653). After a median follow-up time of 25.1 months, the 1- and 2-year OS rates were 93.7% and 86.2% for the PF group and 87.3% and 69.1% for the DP group, respectively (P = 0.364). The 1- and 2-year PFS rates were 77.4% and 55.0% for the PF group and 78.8% and 69.4% for the DP group, respectively (P = 0.845). Grade 3/4 leukocytopenia/neutropenia (68.9% vs. 19.5%, P < 0.001) was significantly more common in the DP group. Conclusion: The treatment response, OS and PFS associated with using CCRT with the DP regimen were not superior to those associated with using CCRT with the PF regimen as a first-line treatment in patients with ESCC. Additionally, the DP regimen was associated with more severe haematological toxicities. This trial has been registered with the US National Institute of Health (clinicaltrials.gov, Identifier NCT 02969473).
