1976年4月至10月应用~(60)Co加X线联合治疗鼻咽癌颈转移淋巴结154例,全部均取分段放射治疗方法。颈野第一段用~(60)Co前后分隔照射,肿瘤量3000拉德/22天,第二段X线垂直照射,肿瘤量2675拉德/18天,中间休息一个月,治疗结束时发生口干咽痛,皮肤反应较轻,后期放疗后遗症发生率低。治疗结束时肿瘤消退率为86.4％,5年内颈淋巴无复发120例,占77.9％。 本文对~(60)Co前后分隔照射的方法及放射后病例复发的因素进行重点的分析。
From April to October 1976, 154 cases of nasopharyngeal carcinoma metastatic lymph nodes were treated with 60Co plus X-rays, all of which were treated by segmental radiotherapy. The first segment of cervical field was separated by irradiation with ~(60)Co before and after irradiation. The tumor volume was 3000 rad/22 days, the second X-ray vertical irradiation, the tumor volume was 2675 rad/18 days, and the middle rest period was one month. The treatment took place at the end of treatment. Dry mouth, sore throat, lighter skin reactions, low incidence of sequelae of late radiotherapy. At the end of treatment, the tumor regression rate was 86.4%. Within 5 years, there were no recurrences of cervical lymph nodes in 120 cases, accounting for 77.9%. This article focuses on the method of separating irradiation before and after ~(60)Co and the factors of recurrence after radiation.
