本文报道1975年至1980年放射治疗鼻咽癌1,101例的回顾性分析。相对 5年生存率为50.1％。鼻咽癌的5年生存率与年龄、颈淋巴结转移情况、原发灶大小及颅底颅神经侵犯等关系较为明显。对颈淋巴结转移灶的照射、放射源的选择与生存率关系甚密。两种射线综合(~(60)COγ+电子束)应用,其5年生存率(62.9％)明显高于单纯(~(60)Coγ)照射组(37.3％)。本资料说明鼻咽癌治疗失败的主要原因是远处转移(37.1％)及局部复发(24％),而死于颈淋巴结复发者仅占3.7％。
This article reported a retrospective analysis of 1,101 nasopharyngeal carcinomas treated with radiotherapy from 1975 to 1980. The relative 5-year survival rate was 50.1%. The 5-year survival rate of nasopharyngeal carcinoma is significantly related to age, lymph node metastasis, size of primary tumor, and skull base cranial nerve invasion. There is a close relationship between the irradiation of cervical lymph node metastases, the choice of radiation source and the survival rate. The 5-year survival rate (62.9%) of the two radiographic (~(60)COγ+ electron beam) applications was significantly higher than that of the pure (~(60)Coγ) irradiation group (37.3%). This data shows that the main reasons for the treatment failure of nasopharyngeal carcinoma were distant metastasis (37.1%) and local recurrence (24%), while those who died of cervical lymph node recurrence accounted for only 3.7%.
