Abstract
From an inception cohort of 204 patients with squamous cell carcinoma of the true vocal cord classified as T2N0 and a minimum of 3 years of follow-up, the authors compare the oncological and functional outcomes following vertical partial laryngectomy (group 1; 85 patients) and supracricoid partial laryngectomy (group 2; 119 patients). The 10-year actuarial survival estimate was 46.2% for group 1 and 66.4% for group 2. Survival was statistically more likely to be reduced (p = .019) in group 1 than in group 2. The 10-year actuarial local control estimate was 69.3% for group 1 and 94.6% for group 2. Local recurrence was statistically more likely to occur (p < .0001) in group 1 than in group 2. Salvage treatment resulted in an overall 94.1% local control rate and a 78.1% laryngeal preservation rate for group 1 and an overall 99.2% local control rate and a 94.9% laryngeal preservation rate for group 2. The 10-year actuarial nodal control estimate was 81.7% for group 1 and 93.7% for group 2. Nodal recurrence was statistically more likely to occur (p = .028) in group 1 than in group 2. The 10-year actuarial estimate for patients without distant metastasis was 84.6% for group 1 and 95.1% for group 2. Distant metastasis was statistically more likely to occur (p = .05) in group 1 than in group 2. The hospital mortality rate was 1.2% for group 1 and 0.8% for group 2. The incidence of permanent gastrostomy was 0% for group 1 and 2.4% for group 2. The incidence of permanent tracheostomy was 1.2% for group 1 and 2.4% for group 2. The incidence of completion laryngectomy due to functional problems was 1.2% for group 1 and 0.8% for group 2.
