Abstract
We have performed laser-radiation combined therapy for stage I and II laryngeal cancers in order to preserve the larynx. In the present study, we retrospectively investigate the factors affecting the preservation of the larynx in stage II laryngeal cancer. The subjects consisted of 34 patients with stage II laryngeal cancer treated between 1988 and 1996 and observed for more than 2 years. Cases with involvement of the ventricle or false cord and those with impaired vocal cord movement showed a tendency towards the loss of their larynx. Moreover, these failures required a longer period to irradiate 1 gray on average than cases which led to a successful preservation of the larynx.
