目的　分析鼻咽癌首程 刀治疗的利弊。方法　 1995年 7月至 1998年 10月我科收治了 9例鼻咽癌首程 刀治疗后的患者 ,原发灶中心剂量 4 0～ 50Gy ,边缘剂量 18～ 2 5Gy ,疗后 1周内来我科补充颈部外照射。颈部淋巴结阳性者照射 6 0～ 70Gy ,阴性者照射 4 5～ 50Gy。结果　 4例在1～ 2年内原发灶复发 (占 4 4 4 % ) ,再作放疗后 2例存活 ,2例死亡。现存活 7例中 ,1例 3年后骨转移 ,正在接受治疗。结论　鼻咽癌首程 刀治疗后短期内原发灶复发率较高 ,疗效不优于常规放疗。 Objective To analyze the pros and cons of nasopharyngeal carcinoma in the first stroke. Methods From July 1995 to October 1998, 9 patients with nasopharyngeal carcinoma treated by first stroke knife were treated in our department. The central dose of the primary tumor was 40-50 Gy and the marginal dose was 18-2 5 Gy. Within 1 week after treatment, Our department supplements external neck radiation. Cervical lymph node positive irradiation 60 ~ 70Gy, negative irradiation 45 ~ 50Gy. Results In 4 cases, the primary tumor recurred (44.4%) within 1 to 2 years and survived 2 cases after radiotherapy and 2 died. Among the seven surviving cases, one had bone metastases 3 years later and was undergoing treatment. Conclusion The recurrence rate of primary tumor in nasopharyngeal carcinoma after the first stroke treatment is higher than that in conventional radiotherapy.
