Therapeutic outcomes of laryngeal cancer at Kyoto University Hospital for 10 years

Abstract

Five-year disease-specific survival rates were 100%, 96%, 100%, and 68% for stage I, II, III, and IV, respectively. Five-year laryngeal preservation rates were 98%, 100%, 86%, 0%, and 0% for T1a, T1b, T2, T3, and T4 of glottic cancer, respectively. Local recurrence occurred in five cases of stage I/II glottic cancer, which was successfully salvaged. Regional lymph node recurrence occurred in five cases including four patients with glottic cancer and one with supraglottic cancer. Two of them died of disease despite undergoing salvage therapy. Distant metastasis occurred in the lung in four cases including one glottic and three supraglottic cancer patients after initial treatment.
