Four hundred forty-eight patients with laryngeal cancer were treated in our department between 1973 and 1992. There were 114 supraglottic (25.4%), 330 glottic (73.7%) and four subglottic tumors (0.9%). The male to female ratio was approximately 12 :1, and the mean age of patients was 63.4 years. According to the TNM classification of malignant tumors proposed by the UICC (1987), eight cases of supraglottic tumor (7.0%) were stage I , 29 (25.4%) stage , 26 (22.8%) stage M , and 51 (44.8%) stage

Fifteen cases of glottic tumor (4.6%) were stage 0, 134 (40.5%) stage I, 99 (30.0%) stage II, 60 (18.2%) stage M , and 22 (6.7%) stage IV, One case of subglottic tumor (25.0%) was stage I, and three (75.0%) stage III. The early stage cases (stage I , II) were predominant in the glottic type, while advanced stage cases (stage El , IV) were predominant in the supraglottic type. In 58 cases of supraglottic tumor (50.9%), total laryngectomy was performed, and in 197 cases of glottic tumor (59.7%), radiotherapy was chosen as the initial treatment. Laryngeal function was preserved in approximately 65% of all cases. The 5-and 10-year survival rate in supraglottic tumor were 55.7% and 50.0%. In glottic tumor, 80.7% and 75.7%. In subglottic tumor, 100.0% and 100.0% respectively. The 5-and 10-year survival rate were 75.9% and 68.7% in the entire series.
