OBJECTIVE: This Phase II study was conducted to evaluate the activity and feasibility of a regimen of nedaplatin and 5-fluorouracil as induction chemotherapy, followed by intensity-modulated radiotherapy concurrent with chemotherapy in patients with locoregionally advanced nasopharyngeal carcinoma. METHODS: Patients received neoadjuvant chemotherapy comprised two cycles of 5-fluorouracil at 700 mg/m(2)/day administered on days 1-4 as continuous intravenous infusion and nedaplatin (100 mg/m(2) administered i.v. over 2 h) given after the administration of 5-fluorouracil on day 1, repeated every 3 weeks, followed by intensity-modulated radiotherapy concurrent with nedaplatin. During intensity-modulated radiotherapy, nedaplatin was administered at a dose of 100 mg/m(2) intravenous infusion on days 1, 22 and 43, given approximately 60 min before radiation. RESULTS: Fifty-nine (95.8%) of the 60 patients were assessable for response. Thirty-eight cases of complete response and 14 cases of partial response were confirmed after completion of chemoradiation, with the objective response rate of 86.7% (95% CI, 78.1-95.3%). The median follow-up period was 48 months (range, 30-62 months). The 3-year progression-free survival and overall survival were 75.0% (95% CI, 63.0-87.0%) and 85.5% (95% CI, 75.9-95.1%). No patient showed Grade 3 or higher renal dysfunction. The most commonly observed late effect was xerostomia, but the severity diminished over time, and the detectable xerostomia at 24 months was 10.2%. There were no treatment-related deaths during this study. CONCLUSIONS: Neoadjuvant chemotherapy with nedaplatin and 5-fluorouracil followed by concomitant nedaplatin and intensity-modulated radiotherapy is an effective and safe treatment for Southern China patients affected by locoregionally advanced nasopharyngeal carcinoma.
