Study of DC-CIK to Treat NPC

Concurrent of radiotherapy and chemotherapy is the main treatment method for patients with nasopharyngeal carcinoma (NPC). However, Relapse remains the major cause of treatment failure. A series of studies reported that dendritic and cytokine-induced killer cells (DC-CIK) have a broad anti-tumor spectrum. We suppose that DC-CIK will improve the prognosis of NPC. In this study, the patients with NPC will be treated with DC-CIK cells after concurrent of chemotherapy and radiotherapy. The purpose of this study is to evaluate the efficacy of DC-CIK for NPC.
