Abstract
A retrospective study was conducted to evaluate the clinical outcomes of 17 patients with T3 glottic squamous cell carcinoma in our hospital between January 2000 and December 2011. The 3- and 5-year overall survival rates were 76% and 63%. The 3- and 5-year cause-specific survival rates were 87% and 78%. Larynx preservation rates were both 29%. None of the larynx preservation cases had invasion of thyroid cartilage at the time of pre-treatment. It may be possible to preserve the larynx in cases without invasion of thyroid cartilage.
