1969.1.1 - 1981.12.31 The authors treated 59 cases of pathologically confirmed nasopharyngeal carcinoma, according to clinical and X-ray examinations, according to the US Joint Commission staging criteria established by the 1977 cancer, which has no distant metastasis IV total of 45 example. The 45 patients received radical radiotherapy and the irradiation techniques were basically the same. The irradiation source is a Co~(60) or 4~6Mev linear accelerator. The first site of the nasopharyngeal cavity, skull base, and lymphatic drainage was illuminated with two parallel pairs of fields. Lesions invading the nasal cavity plus a front field. The double-necked neck is conventionally irradiated with a front field, and then the field is inflated according to the lymphatic metastasis of the area. Each field is shot every day for 200 cGy per week.
