Objective: To understand the therapeutic effect of supplementary radiotherapy on primary residual tumor of nasopharyngeal carcinoma and to analyze the related factors that may affect the curative effect. Methods: From October 1988 to March 1995, 82 patients with residual primary lesions were treated with external irradiation and intracavitary brachytherapy to supplement radiotherapy. Results: The overall 5-year survival rate, tumor-free survival rate and local control rate were 51.2%, 48.8% and 73.2% respectively. Analysis of the single external irradiation, intracavitary brachytherapy and the combination of both treatment. Conclusion: Local residual lesions of nasopharyngeal carcinoma patients with radiotherapy is necessary and valuable, in the treatment may consider the use of some unconventional treatment options
