[Application of laser surgery to the treatment of laryngeal cancer].
The authors utilized CO2 laser to treat laryngeal cancer in 28 patients. The operative methods were the following: Method I. Glottic T1 tumor was completely vaporized by laser irradiation alone. This method was employed in cases without involvement of the anterior commissure and cartilagenous portion. Method II. Radiotherapy was carried out after removal of major lesion by laser surgery. The purpose of this method was to improve the success rate of radiotherapy. Method III. After radiotherapy laser surgery was done to remove residual tumor as far as possible in patients who could not undergo radical surgery due to poor general condition. Method I, or complete tumor resection by laser surgery alone, seemed profitable because of short admission period. It is, however, indispensable to select patients suitable for this treatment. Method II permitted improving the success rate of radiotherapy. Even after vaporizing major lesion by laser irradiation, 60Gy irradiation was required. Method III, or laser surgery on postradiation residual tumor was often useful to treat the patients with poor general condition or who refused more radical surgery.
