BACKGROUND/AIM: To further improve the prognosis of locally advanced esophageal cancer patients, investigating new perioperative treatment strategies is necessary. The current study aimed to retrospectively investigate neoadjuvant radiotherapy with cisplatin and 5-fluorouracil (CF-RT) and radiotherapy with docetaxel and CF (DCF-RT) and compare their treatment outcomes in patients with locally advanced esophageal squamous cell carcinoma (ESCC). PATIENTS AND METHODS: We retrospectively reviewed 95 patients with ESCC who received CF-RT or DCF-RT followed by esophagectomy. The CF-RT group received chemotherapy consisting of two courses of CF repeated every 4 weeks. The DCF-RT group received chemotherapy consisting of two courses of DCF repeated every 2 weeks. A radiotherapy dose of 1.8-2 Gy was administered per session, up to a total of 40-41.4 Gy. Adverse events of neoadjuvant chemoradiotherapy, surgical outcomes, pathological responses, prognosis, and recurrence patterns were evaluated. RESULTS: Both the CF-RT and DCF-RT groups had equivalent pathological complete response rates of the primary tumor at 31.6% and 38.6%, respectively. However, the DCF-RT group had significantly better 5-year disease-free survival and 5-year overall survival than (HR=0.50, 95%CI=0.26-0.97, p=0.0392) than the CF-RT group. CONCLUSION: DCF-RT may be a candidate neoadjuvant therapy for locally advanced ESCC.
