Clinical Study of Laryngeal Carcinoma

Abstract

We retrospectively analyzed 178 patients with laryngeal carcinoma treated at our department from 2007 to 2014. The cases included 125 glottic and 53 supraglottic cancers. The 3-year disease specific survival rates were 95.4% in the glottic cancer group and 83.7% in the supraglottic cancer group. In T3 patients treated with radiotherapy or chemoradiotherapy, the 3-year laryngeal preservation rates were 70% in the glottis cancer group and 100% in the supraglottic cancer group. .

In T3 glottic cancer, the radiation failure rate was 50% for the cases of vocal cord fixation, and 14% for the cases of paraglottic space invasion. Laryngeal preservation therapy is indicated for patients with T3 carcinoma with paraglottic space invasion.
