Docetaxel+Cisplatin+5-FU (DCF) Therapy as a Preoperative Chemotherapy to Advanced Esophageal Squamous Cell Carcinoma: A Single-center Retrospective Cohort Study.

Objective The aim of this study was to determine the safety and clinical efficacy of docetaxel+cisplatin+5-fluorouracil (DCF) as neoadjuvant chemotherapy (NAC). Methods In this single-center study, patient background and treatment outcomes (NAC efficacy assessment, NAC adverse events, short-term postoperative outcomes, and one-year postoperative outcomes) in patients treated with preoperative DCF and preoperative cisplatin+5-FU (CF) were compared retrospectively. Patients Seventeen patients diagnosed with esophageal squamous cell carcinoma (ESCC) and treated with preoperative DCF therapy and 50 patients treated with preoperative CF therapy between January 2013 and July 2019 were included in this study. Results There were significant differences in clinical T factor and clinical stage between the CF and DCF groups (p<0.05). All patients in the DCF therapy group were above clinical T3 and clinical stage III. The clinical response after NAC was partial response (PR) for 23 patients (46.0%) in the CF group and 13 patients (76.5%) in the DCF group (p=0.030). Regarding adverse events in NAC, neutropenia, febrile neutropenia (FN), diarrhea, and stomatitis were observed more frequently in the DCF group than in the CF group (p<0.05). The postoperative results [overall survival (OS), recurrence-free survival (RFS), one-year OS, one-year RFS] of the DCF group were comparable to those of the CF group. Conclusion DCF therapy has been recognized as an effective treatment option for advanced ESCC. However, the indication for DCF therapy should be chosen carefully because of the high incidence of adverse events.
