Induction chemotherapy with cisplatin and gemcitabine followed by accelerated radiotherapy and concurrent cisplatin in patients with stage IV(A-B) nasopharyngeal carcinoma.

BACKGROUND The purpose of this study was to evaluate the efficacy and toxicity of cisplatin plus gemcitabine as induction chemotherapy in advanced nasopharyngeal carcinoma (NPC). METHODS Thirty-seven patients with stage IV(A-B) NPC were treated with 3 cycles of cisplatin plus gemcitabine (cisplatin 80 mg/m(2) on day 1; gemcitabine 1250 mg/m(2) on days 1 and 8) 3-weekly as induction chemotherapy, followed by another 3 cycles of concurrent cisplatin (100 mg/m(2) on day 1) 3-weekly with accelerated radiotherapy (RT) at 70 Gy in 2-Gy fractions, 6 daily fractions per week. RESULTS The overall response rate to induction chemotherapy was > 90%, and side effects other than uncomplicated hematologic toxicities were uncommon. All patients completed RT, with 92% receiving > or = 5 cycles of chemotherapy. At a median follow-up of 2.9 years, the 3-year overall survival (OS) and disease-free survival (DFS) rates were 76% and 63%, respectively. CONCLUSIONS Cisplatin plus gemcitabine is a well-tolerated, effective, and convenient induction chemotherapy regimen and warrants further studies to confirm its benefit in advanced NPC.
