The author discussed radiation therapy for head and neck malignancies at National Cancer Center. 147 cases of head and neck malignancies were first treated with radiation and their 5-year survival ratio was 61%. In the cases which survived for 5 years, most of the patients were treated with Telecobalt or Ra-needle insertion but recently Lineac and Betatron are chiefly employed, especially in treatment of cancer of the tongue.To improve the method of intracavitary radiation in maxillary cancer after-loading applicator is adopted and the author maintained that computer should be employed for accurate calcuration of radiation dosis.
