Abstract
The radiation therapy of laryngeal cancer has changed in these ten years in our country. We have been observed 72 patients of laryngeal cancer, who admitted to our clinic, about the method of their therapy, dosage, function of speaking and the prognosis. Among the 72 patients, the observations were gained by 59 patients as follows;
1. The therapeutic method has changed from Ra therapy to Co 60 irradiation in these nine years. All the patients who admitted after 1970 were treated by Co 60 therapy.
2. In 59 patients, Ra therapy was applicated to 31 patients and 28 patients were treated by Co 60 therapy.
3. The average dosage of Ra therapy was 11,090 rads and that of Co 60 therapy was 6,950 rads.
4. The five year survival of Ra therapy was 95%, though the five year survival of Co 60 therapy was 56%.
5. The dosage of radition was not relative to the survival of the patients in our observance.
6. As to the 9 patients who died after discharge,. no relation was seen between their dosage and death rate, which may suspect the proper dosage on radiation therapy of laryngeal cancer. The proper dosage on our observation of Co 60 therapy was 6,000 rads.
