METHODS: A total of 180 patients with stage Ⅲ or Ⅳa NPC diagnosed pathologically were randomly divided into chemotherapy plus radiotherapy group (CT/RT group) and radiotherapy alone group (RT group). Cisplatinbased induction chemotherapy was performed in CT/RT group for 2 cycle (DFP, TFP, in 47 cases; PF, PFB, EFP in 43 cases) and radiotherapy was started in 1 week after the last chemotherapy. The methods of radiation were the same in both groups. RESULTS: The distant metastasis free survival (DMFS) rates in 3 and 5 years were 88.9%, 82.2% and the relapse free survival (RFS) rates in 3 and 5 years were 75.6%, 67.8% in CT/RT group; the 3, 5year DMFS rates were 72.2%, 65.6% and the 3, 5year RFS rates were 71.1%, 64.4% in RT group; there was no differences of statistical significance in 3, 5year RFS rates (P=0.089, P=0.076), but there was statistically significant difference in 3, 5year DMFS rates (P=0.029, P=0.024). The therapeutic effect of induction chemotherapy project including paclitaxel such as DFP, TFP was more excellent than classical chemotherapy projects such as FP, FBP, EFP (3, 5year DMFS: P=0.019, P=0.022). The acute oral mucositis of Ⅲ, Ⅳ degree and leucopenia in the former groups were much more severe than those in the latter groups (51.1% vs 30.2%, P=0.018; 34.0% vs 14.0%, P=0.07). But these adverse eactions can be tolerable by using GCSF. There were no cases or death of allergy correlated to treatment. No patients need to decrease the dose of chemotherapy or radiation or to terminate the treatment, or to delay the late radiotherapy. CONCLUSION: The chemoradiotherapy can decrease si
