Background: This single-center, phase II study assessed the safety/tolerability and initial efficacy of gefitinib in patients with nasopharyngeal carcinoma (NPC) pretreated with platinum-based chemotherapy.
Methods: Patients with recurrent and metastatic NPC who had treatment failure with at least 2 lines of chemotherapy including platinum were given gefitinib at a fixed dose of 250 mg daily. Treatment was continued until the patient experienced unacceptable side effects or disease progression.
Results: Nineteen patients were enrolled, having had treatment failure with a median of 2 chemotherapy regimens. Treatment was well tolerated, and only grades 1 to 2 adverse events were observed. None of the patients achieved partial or complete response. Median time-to-progression was 4 months, and median overall survival was 16 months.
Conclusion: Gefitinib was well tolerated, but the response rate was poor in this heavily pretreated study population, and its use in NPC is not recommended outside the context of clinical trial.
