Clinical Study of Laryngeal Cancer

Abstract

We reviewed 94 patients with laryngeal cancer who were treated at Tokushima University Hospital during the 7 years between January 1982 and December 1988. The male/female ratio was-8: 1. The 94 patients included 51 (54.2%) with glottic cancer,37 (39.4%) with supraglottic cancer, and 6 (6.4%) with subglottic cancer.
According to the 1978 UICC TNM classification system,22 patients (23.4%) were in stage I,22 (23.4%) were in stage II,26 (27.7%) were in stage III, and 24 (25.5%) were in stage IV.
The five-year survival rate was 66.4% for patients with laryngeal cancer (stage I,87.2%; stage II,63.3%; stage III,63.5%; and stage IV,50.0%),77.3% for patients with glottic cancer (stage I,87.5%; stage II,100.0%; stage III,76.9%; and stage IV,14.8%), and 54.7% for patients with supraglottic cancer (stage I,83.3%; stage II,40.0%; stage III,30.0%; and stage IV,60.4%). For patients with subglottic cancer, it was 66.7%.
We had 2 cases of supraglottic cancer which were classified as T₁ lesions according to the 1987 UICC system, althrough they were T₄ lesions according to the 1978 UICC system.
