Three-arm Phase III Trial Comparing Cisplatin Plus 5-FU (CF) Versus Docetaxel, Cisplatin Plus 5-FU (DCF) Versus Radiotherapy with CF (CF-RT) as Preoperative Therapy for Locally Advanced Esophageal Cancer (JCOG1109, NExT Study)

A three-arm Phase III trial was started in November 2012. Preoperative chemotherapy with cisplatin plus 5-fluorouracil is the current standard treatment for locally advanced esophageal cancer in Japan, while preoperative chemoradiotherapy with cisplatin plus 5-fluorouracil is the standard in Western countries. Preoperative chemotherapy with docetaxel, cisplatin plus 5-fluorouracil is another promising regimen. The purpose of this study is to confirm the superiority of docetaxel, cisplatin plus 5-fluorouracil over cisplatin plus 5-fluorouracil and the superiority of cisplatin plus 5-fluorouracil with chemoradiotherapy over cisplatin plus 5-fluorouracil as preoperative therapy for squamous cell carcinoma of esophagus. A total of 501 patients will be accrued from 41 Japanese institutions within 6.25 years. The primary endpoint is overall survival and the secondary endpoints include progression-free survival, %R0 resection, response rate, pathologic complete response rate and adverse events.
