Abstract

OBJECTIVE: To study the treatment to head and neck-late recurrence tumors by using multi-bullet radiofrequency therapy. METHOD: Eleven patients with late recurrence head and neck tumors were treated by using multi-bullet radiofrequency therapy. Before and after the therapy, the tumor size, pathologic alteration were assessed. The serial changes in tumor size after therapy were evaluated with CT imaging. The effects, side-effects and indications of this therapy were observed also. RESULT: The ablation, coagulation and necrosis of tumors were observed during the multi-bullet radiofrequency therapy in all this 11 patients. The tumors disappeared in CT scanning during 1.2-2.6 years follow up. CONCLUSION: Our study suggests that the multi-bullet radiofrequency therapy is a safe and effective treatment for patients with head and neck late recurrence tumors.
