[Long-term results of total versus partial laryngectomy for the treatment of squamous-cell carcinoma of the larynx].
OBJECTIVE
To analyze the long-term effects of total versus partial laryngectomy for the treatment of squamous-cell carcinoma of the larynx.


METHODS
Of 423 patients with laryngeal carcinoma surgically treated, 327 had supraglottic cancer and 96 had glottic cancer. Total laryngectomy was performed in 243 patients (210 supraglottic and 33 glottic cancers) and partial laryngectomy in 180 patients (117 supraglottic and 63 glottic cancers).


RESULTS
The overall 5-year survival rate of patients with supraglottic carcinoma was 72.9%. That of patients treated by total and partial laryngectomy was 70.1% and 77.4%, respectively (P > 0.05). The overall 5-year survival rate of patients with glottic carcinoma was 86.0%. That of patients treated with total and partial laryngectomy was 72.2% and 92.3%, respectively (P < 0.05).


CONCLUSIONS
The long-term result of partial laryngectomy for glottic carcinoma is as good as total laryngectomy, and for supraglottic carcinoma, partial laryngectomy is superior to total laryngectomy. Partial laryngectomy is recommended to treat patients with squamous-cell carcinoma of the larynx. Patients so treated have a better quality of life.
