Abstract
• We reviewed 173 laryngeal specimens that included thyroid tissue received from patients undergoing laryngectomy between 1966 and 1980 for evidence of thyroid gland invasion. Twenty-three (14%) of the larynges demonstrated thyroid involvement. In 15 specimens, involvement of the thyroid gland was by direct extension, and in eight the thyroid was involved metastatically. The survival in this group of patients was poor, with 18 patients dying of their disease within three years. Subglottic extension of 10 mm or greater was noted in 21 of 23 patients, and local recurrence was noted in 15 of 18 patients dying of their disease. The importance of removing one or both lobes of the thyroid gland in advanced laryngeal cancer is restated, and a surgically aggressive approach to the paratracheal nodes is recommended in patients with extensive subglottic involvement.
