Abstract
The purpose of this paper is to evaluate the relapse-free survival and the overall survival at three years of 39 laryngeal cancers (10 T1 and 29 small recurrent carcinomas with mobile vocal cord) operated on by CO2 laser surgery at the Istituto Nazionale Tumori in Milan from 1982 to 1987. The 10 patients with T1 cancers had two local recurrences, whereas the 29 patients with recurrent carcinomas had 14 local recurrences. Local relapses occurred in 2/16 patients with cancer limited to the vocal cord and in 9/17 patients with glottic tumors extended to the anterior commissure or to the ventricular band or to the arytenoid. Supraglottic cancers recurred in 3/4 patients. The authors conclude that transoral laser surgery is an effective modality for treatment of T1 primary and small recurrent carcinomas of the larynx, when limited to the middle third of the vocal cord.
