Results of neoadjuvant chemoradiotherapy with docetaxel and 5-fluorouracil followed by esophagectomy to treat locally advanced esophageal cancer.

e15084 Background: Esophageal cancer is most frequently treated with platinum-based chemoradiotherapy (CRT). We previously described a Phase I study of definitive CRT with docetaxel (DOC) and 5-fluorouracil (5FU) in patients with advanced esophageal cancer. This regimen had low toxicity and was effective without platinating agents. The present study aims to determine the antitumor effects of neoadjuvant CRT with DOC and 5FU and surgical outcomes. Methods: We reviewed data from 38 patients with locally advanced cancer of the esophagus or esophagogastric junction who underwent trimodality therapy comprising neoadjuvant CRT with DOC and 5FU followed by esophagectomy between 2003 and 2008. Results: Esophagitis was the most common toxicity associated with neoadjuvant CRT (Grade 3; 26.3%), and hematological toxicity was mild. Transthoracic esophagectomy and pharyngolaryngoesophagectomy proceeded in 36 (94.7%) and 2 (5.3%) patients, respectively, and 35 (92.1%) underwent R0 resection. Five (13.2%) patients had complete pathological responses (pCR) of the primary tumor, and 23 (60.5%) had pathological reductions of over two-thirds of the primary tumor. T or N status was also down-staged in 26 (68.4%) patients. Overall postoperative morbidity developed in 21 (55.3%) patients, and mortality due to postoperative morbidity was zero. The five-year recurrence-free and overall survival rates were 39.5% and 44.7%, respectively. Conclusions: The rate of neoadjuvant CRT toxicity and postoperative complications were acceptable, and the complete resection rate and survival data were favorable. This regimen is promising as neoadjuvant CRT for esophageal cancer and very useful as an alternative regimen for treating patients with esophageal cancer who cannot tolerate cisplatin.
