Abstract
From 1990 through 1998, 143 patients with laryngeal cancer were treated in our department. Of the 143 patients, 94 had glottal, 43 had supraglottal, and 6 had subglottal cancer. The 5-year survival rate in patients with laryngeal cancer was 90.0% for stage I, 81.3% for stage II, 77.9% for stage III, and 42.6% for stage IV. The 5-year survival rate was 86.5% for glottal, 55.9% for supraglottal and 66.7% for subglottal cancer patients. The laryngeal preservation rate was 90.4% for stage I, 60.5% for stage II, 21.4% for stage III and 28.1% for stage IV.A loco-regional recurrence occurred in 24 of 143 patients (16.8%). The salvage rate for these patients was 45.8% (11/24). Six of 11 patients who died of primary disease and nodal failure (including 2 stomal recurrences) had supraglottic stage N carcinoma.In conclusion, laryngeal preservation surgery should be recommended in the early stages of cancer after radiation failure and local recurrence. It is recommended to dissect the anterior compartment including the delphian lymph node, pretracheal, and parathyroidal nodes bilaterally for patients with laryngeal tumors that have significant anterior subglottic extension, tumors arising in the subglottic region, or advanced tumors arising in any region, especially the supraglottis.
