Objective: To evaluate the effect of brachytherapy intracavitary residual tumor on patients with NPC after radiation therapy Methods: Five hundred sixty three NPC with residual tumor in the nasopharynx were treated with large dose of brachytherapy (2025 Gy) The treatment results were retropectively evaluated Results: Within 3 months after brachytherapy, the overall regression rate of the residual tumor was 90 4% Upon long term follow up, the 1 , 3 and 5 year survival rate was 89 65%, 67 01% and 55 42%, respectively The major complications of the after loading treatment were nasal obstruction (16 2%), necrosis of the nasopharynx (0 9%) and perforation of soft foliate in 2 patients Conclusion Brachytherapy is effective in the treatment of residual NPC especially in patients in early stage It may not be helpful to stage IV patients
