Prognostic Advantage of Docetaxel/Cisplatin/ 5-Fluorouracil Neoadjuvant Chemotherapy in Clinical Stage II/III Esophageal Squamous Cell Carcinoma due to Excellent Control of Preoperative Disease and Postoperative Lymph Node Recurrence

Background: Neoadjuvant chemotherapy (NAC) has become prevalent in esophageal squamous cell carcinoma (ESCC), but its long-term prognostic advantages remain unclear. The latest prognostic outcomes in clinical Stage (cStage) II/III ESCC with NAC were herein elucidated. Patients and Methods: NAC prior to curative treatment was done in 115 cStage II/III ESCC patients with either cisplatin (CDDP)/5-fluorouracil (5-FU; CF) (n = 41) or docetaxel/CDDP/5-FU (DCF) NAC (n = 74) between 2007 and 2013. Results: (1) Esophagectomy was finally performed in 35 of the 41 CF NAC cases and in 48 of the 74 DCF NAC cases. The preservation rate of the esophagus was higher in the DCF NAC than in the CF NAC (p = 0.018). (2) The overall survival was better in DCF NAC than in CF NAC (p = 0.071), and progression-free survivals were 58.3% with DCF and 30.5% with CF (p = 0.0060). DCF NAC was associated with fewer cases of progression than CF NAC (p = 0.0040), largely due to excellent control of the preoperative disease (p = 0.018) and postoperative lymph node recurrence (p = 0.014). Conclusion: DCF NAC in cStage II/III ESCC could have a great potential to achieve a better prognosis due to suppression of specific progression events with a higher preservation rate of the esophagus.
