Phase II Study of Docetaxel, Nedaplatin, and 5-Fluorouracil Combined Chemotherapy for Advanced Esophageal Cancer

We performed a prospective, multi-institutional, phase-II, clinical trial of a docetaxel, nedaplatin, and 5-fluorouracil (DNF) regimen in patients with unresectable esophageal cancer. Our goal was to determine the efficacy and feasibility of this DNF protocol. Thirty-four patients with unresectable esophageal cancer were enrolled and received DNF therapy. The DNF regimen was repeated every 4 weeks for up to 8 weeks, based on the following recommended doses: docetaxel, 60 mg/m(2) (day 1); nedaplatin, 70 mg/m(2) (day 1); and 5-fluorouracil, 700 mg/m(2) (days 1-5). The primary endpoint was the response rate. The secondary endpoints were overall survival and chemotherapy toxicities. The complete response rate and response rate were 5.9 and 47.1 %, respectively. The 2-year overall survival rate and progression-free survival rate were 44.3 and 27.3 %, respectively. The median survival time was 594 days. The median progression-free time was 277 days. No treatment-related deaths occurred. Thirty patients (30/34) with grade 3, 4 neutropenia improved relatively quickly with administration of granulocyte colony-stimulating factor. DNF combination chemotherapy is a useful regimen with relatively minor adverse events and may serve as an effective protocol in patients with unresectable esophageal cancer.
