Nineteen patients with transglottic cancer were reviewed, between September 1986 and December 1999. They were classified as T2 in 8 patients, T3 in 7, T4 in 4, N0 in 13, N1 in 2 and N2 in 1. All patients underwent total laryngectomy with modified neck dissection including one patient in whom a full course of radiation therapy failed. The five-year survival rate was 68.4%. Main cause of death was distant metastases. There were no difference in survival rates between lateral type and anterior type. There was a significant difference in survival rates between the group without neck metastasis and the group with neck metastases. We indicated the poorer prognosis for cases with transglottic cancer rather than other types of laryngeal cancer, and stressed the difficulty of early diagnosis and treatment.
