Clinical Study of 97 Cases of Laryngeal Cancer

Abstract

Ninety-seven cases of laryngeal cancer, who had been treated at our department between 1994 and 2003, were investigated retrospectively. Of these patients,56 cases were glottis type,31 epiglottic type,3 subglottic type, and 7 transglottic type. The five-year survival rates were overall; 85.4%, stage I 95.0%, stage II 90.6%, stage III 81.9%, stage IV 66.9%. The five-year organ preservation rates for T1 to T4 were 91.9%,67.9%,29.3%, and 18.2% respectively. The present study also included 30 cases with multiple primary cancer, and 11 cases who died of cancers other than laryngeal cancer.
