For these advanced or metastatic NPC, chemotherapy is the most important therapeutics,and they are relatively responsive to chemotherapy compared to other head and neck cancers. The backbone of the treatment for recurrent/metastatic (R/M) NPC is cisplatin containing regimen, which is also regarded as the standard regimen for other squamous cell carcinoma of head and neck (SCCHN). The FP regimen is widely used in R/M NPC patients now and its response rate is around 40%-65%,but the response period is usually short and the adverse reaction is frequent and badly tolerant, which influent the treatment compliance seriously. What's more, the catheters and pumps are necessary for continuous infusion of 5-Fluorouracil, which add to the cost, immobility and inconvenience of the treatment.
