This study was designed to evaluate the anti-tumor activity and toxicity profile of gemcitabine in the treatment of patients with advanced nasopharyngeal carcinoma (NPC) who had been pretreated with platinum-based chemotherapy.
This is an open label, single arm phase II trial. All patients were treated with single agent of gemcitabine. Gemcitabine was given in the dosage of 1.0 g/m2 on days 1, 8, 15, each cycle repeated every 4 weeks. Gemcitabine was added to 100 ml normal saline infused over 30 min.
About 32 patients were enrolled in this trial. Thirty patients were assessable for response to treatment. Fourteen patients had a partial response (PR), giving an overall response rate of 43.8% (14/32); 9 patients had stable disease (28.1%) and 7 progressed disease (21.9%). The median time to progression was 5.1 months and median survival time was 16 months, 1 year survival rate was 67%, 2 year overall survival rate was 12%. A total of 11 patients (34.4%) experienced grade 3 and 4 toxicity and the main toxicity was myelosuppression. the non-hematology toxicity was minimal.
The effectiveness of gemcitabine was higher and side effects were minimal in advanced NPC patients after platinum-based chemotherapy failed.
