目的 :观察12 5I放射性密封源置入组织间治疗晚期头颈癌的疗效。方法 :根据CT评估 ,将12 5I放射性密封源置入到瘤体内、水肿区及周边 2～ 3cm治疗 5例晚期头颈癌。结果 :5例患者局部肿瘤均明显控制 ,疼痛明显减轻。 1例出现皮肤坏死 ,1例出现皮肤坏死和颈内动脉出血。结论 : 12 5I放射性密封源置入为晚期头颈癌的治疗提供了可行的方法 ,但需注意并发症的预防。
Objective: To observe the efficacy of 12 5I radioactive seal source in the treatment of advanced head and neck cancer. Methods :According to the CT evaluation, 12 5I radioactive seal source was placed into the tumor body, edema area and peripheral 2 ~ 3cm to treat 5 cases of advanced head and neck cancer. Results: The local tumors were significantly controlled in 5 patients and the pain was significantly reduced. One patient had skin necrosis, and one patient had skin necrosis and internal carotid artery bleeding. Conclusion : 12 5I radioactive sealed source can provide a feasible method for the treatment of advanced head and neck cancer. However, attention should be paid to the prevention of complications.
