Clinical Study of Laryngeal Cancer

We reviewed 143 patients with laryngeal cancer, who had undergone primary treatment in our hospital between 1983 to 1993. These patients consisted of 45 cases of supraglottic carcinoma, 94 cases of glottic carcinoma and 4 subglottic carcinoma. The respective five-year survival rates were 55.4%, 80.1%, 100% and 72.9% for supraglottic carcinoma, glottic carcinoma, subglottic carcinoma and that over all. Successful radiation control rates for primary glottic carcinoma in stage I and stage II were 89.4% and 76.9%, respectively. Laryngectomy was performed on 65 patients, but the larynx could be preserved in 54.5% of all cases.
