Surgical treatment of invasion of the upper aerodigestive tract by well-differentiated thyroid carcinoma

Forty-eight patients with well-differentiated thyroid carcinoma invading upper aerodigestive tract structures have been described. Age at diagnosis was found to be a negative prognostic factor, and duration of disease before invasion was found to be a positive prognostic factor. Treatment with radical surgery and adjuvant therapy provided no improvement in survival over treatment with near-total (skeletonizing) excisions combined with adjuvant therapy. All patients treated with partial debulking procedures, with or without tracheotomy, died from disease. We believe that partial resection of upper aerodigestive tract structures without sacrifice of voice, normal breathing, or swallowing should be considered in patients with well-differentiated thyroid carcinoma.
