109例30岁以内鼻咽癌,全部经病理证实,使用放射治疗。五年生存率33.9％,结果表明,儿童及青少年鼻咽癌放疗预后:男性优于女性,年幼者优于年长者,未分化癌优于低分化鳞癌。而起病到治疗时间及临床分期与预后之间没有明显关系。本文对儿童及青少年鼻咽癌的放疗野设计及随访重点进行讨论。
109 cases of nasopharyngeal carcinoma within the age of 30 years were confirmed by pathology and radiotherapy was used. The five-year survival rate was 33.9%. The results showed that the prognosis of radiotherapy for nasopharyngeal carcinoma in children and adolescents: men were better than women, young people were better than the elderly, and undifferentiated cancer was better than poorly differentiated squamous cancer. There was no significant relationship between onset to treatment time and clinical stage and prognosis. This article discusses the radiotherapy field design and follow-up focus of nasopharyngeal carcinoma in children and adolescents.
