Objective: To study the use of interventional chemotherapy in comprehensive treatment for advanced nasopharyngeal carcinoma. Methods: Interventional chemotherapy with multi-drugs including cisplatin (DDP) 100 mg, 5-fluorouracil (5-FU) 1000 mg and bleomycin (BLM) 16 mg was used to treat 30 cases with advanced nasopharyngeal carcinoma before radiotherapy. 50 cases that received radiotherapy alone were used as a control group. The methods, time and dose schedule of radiotherapy were similar in the two groups. Results: The primary lesions in 16 cases and the cervical lymph nodes in 12 cases were reduced in size after interventional chemotherapy. Radiation doses of those in complete response in their primary lesion and cervical lymph nodes were lower than that of the control group (P
