Forty consecutive cases of carcinoma of the oropharynx were treated by irradiation from 1973 through 1987. The overall five-year survival rate calculated by the Kaplan-Meier method was 21%. Data were also analyzed retrospectively to investigate the factors associated with prognosis. The following results were obtained. (1) The results of re-irradiation as salvage treatment were poor. (2) Irradiation to neck lymph node metastases was not particularly effective, especially under 50 Gy. (3) Stage T2(-4) primary tumors were difficult to control with irradiation of 50 Gy.
1973年至1987年期间，对40例连续性口咽癌患者进行了放射治疗。采用Kaplan-Meier法计算的总体五年生存率为21%。对数据进行回顾性分析以研究与预后相关的因素。得出以下结果：（1）作为挽救性治疗的再照射效果不佳。（2）对颈部淋巴结转移灶进行照射并非特别有效，尤其是在50 Gy以下时。（3）T2（-4）期原发性肿瘤难以通过50 Gy的照射得到控制。
