[Radiation therapy of T1N0M0 glottic carcinoma: clinical evaluations based on field size, plastic shell and wedge filter].
One hundred forty previously untreated cases of T1N0M0 glottic carcinoma underwent therapy at our department from November 1977 through May 1984. Ninety-six of them were treated with the open-field technique of 4 MVX-ray using parallel opposed fields in bandage up to April 1982 (group I). The remaining 44 cases were treated with the wedge-filtered technique in a plastic shell in order to improve the dose distribution and immobilization during radiotherapy starting in May 1982 (group II). The two-year disease-free survival rates were 85% and 91%, respectively. Thus, better results were achieved by improved treatment techniques.
