Purpose: To explore a more effective strategy for treating nasopharyngeal carcinoma with extensive locoregional disease. Methods and Materials: Between October 1998 and January 2003, 49 patients with Stage IV(A-B) disease infiltrating or abutting neurologic structures were treated with induction-concurrent chemotherapy and accelerated radiotherapy (RT). A combination of cisplatin and 5-fluorouracil was used in the induction phase and single-agent cisplatin in the concurrent phase. All patients were irradiated with conformal techniques at 2 Gy/fraction, six daily fractions weekly, to a total dose of 70 Gy. Results: Although 92% of patients had one or more acute toxicities Grade 3 or worse, 96% completed the whole course of RT, and 92% had five or more cycles of chemotherapy. The great majority of toxicities were uneventful, but 1 patient died of neutropenic sepsis. With a median follow-up of 3.1 years, 20 patients had failure at one or more sites and 15 patients died. The 3-year locoregional and distant failure-free rate was 77% and 75%, respectively, and the overall survival rate was 71%. At last follow-up, 27% of patients had developed late Grade 3 or worse toxicity (24% were hearing impairments), but none had radiation-induced neurologic damage. Conclusion: The current strategy achieved encouraging results for this poor prognostic group, and confirmation of the therapeutic gain by a prospective randomized trial is warranted.
