During 11 years from 1983 to 1994,134 cases of laryngeal cancer were treated. In this paper, the clinical analyses of these patients are reported. There were 127 male and 7 female patients (ratio 18 : 1), and their pathological diagnoses were all squamous cell carcinoma. The primary site of 34 cases was supraglottic type and 96 cases were glottic type. Only 4 cases were subglottic type. All cases were grouped by T classification (UICC in 1987); 57 cases (43%) with T1, 37 cases (26%) with T2, 24 cases (19%) with T3, and 16 cases (12%) with T4. The patients were treated using not only single therapy such as radiotherapy or surgery, but also using combination therapy. The 5-year survival rate up to now was 78.4%, which was a little higher than the rates reported by other investigators.<BR>Also examined were the factors that prevent improvement of the laryngeal cancer cure rate. Based on our long-term observations, examination of the deaths by recurrent cancer revealed the importance of preventing cervical recurrence, especially stomal recurrence. Furthermore, from the examination of other causes of death, it was revealed that early detection of secondary digesitive cancer, particularly esophageal and stomach cancer, is necessary.
