ResumoNasopharyngeal carcinoma (NPC) is a disease that is highly responsive to various chemotherapeutic agents. In the metastatic setting, 2-drug combination chemotherapy generally provides a response rate of 55% to 75%, and median survival of 10 to 12 months. The objective of the current study was to assess the efficacy of a 3-drug combination followed by maintenance treatment in patients with metastatic NPC.Patients with metastatic NPC were treated with a combination of gemcitabine at a dose of 1,000 mg/m(2), paclitaxel at a dose of 70 mg/m(2), and carboplatin at an area under the concentration-time-curve (AUC) of 2.5 on Days 1 and 8 every 21 days. Patients who achieved partial or complete response continued to receive weekly 5-fluorouracil at a dose of 450 mg/m(2) and leucovorin at a dose of 30 mg/m(2) for 48 weeks.Twenty-eight patients were recruited. Twenty-two (79%) patients had >or=2 sites of disease. Toxicities were mainly from bone marrow suppression, with 79% grade 3/4 neutropenia, 32% grade 3/4 anemia, and 29% grade 3/4 thrombocytopenia (according to the National Cancer Institute Common Toxicity Criteria). The overall response rate to the 3-drug regimen was 86%, with a complete response rate of 11%. The median duration of response was 8 months and the median overall survival was 22 months.This regimen of a 3-drug combination followed by maintenance is feasible and has demonstrated an encouraging response rate and overall survival.
