With the extension of survival time in nasopharyngeal carcinoma(NPC), more and more patients suffer from recurrence with radiation brain injury after radiotherapy, recurrence after the second or more courses of radiotherapy, standard treatment failure after recurrence, and first-line treatment failure after multiple distant metastasis. We define these four types as refractory nasopharyngeal carcinoma[1-2] due to the complex and high risk of treatment and poor prognosis. For recurrence and metastasis NPC, the objective response rate ranges from 25% to 46.4% with platinum-based, or 5-Fu-based, or gemcitabine-based salvage chemotherapy[2--5].
