  • Title: Completion thyroidectomy for initially misdiagnosed thyroid cancer.
    Author: Auguste LJ, Attie JN.
    Journal: Otolaryngol Clin North Am; 1990 Jun; 23(3):429-39. PubMed ID: 2195432.
    Abstract:
    Intraoperative frozen sections fails to diagnose thyroid carcinoma accurately in 16% of cases. In such instances, we recommend that completion thyroidectomy be performed in the patient who has invasive carcinoma, is less than 70 years old, and has a reasonable life expectancy. The procedure should be carried out immediately if the error in diagnosis is discovered within a week; otherwise the procedure should be delayed until 3 to 4 months later. At that time, the recurrent laryngeal nerves and at least two parathyroid glands should be dissected and preserved. A paratracheal lymph node dissection should also be performed and the lower jugular lymph nodes should be sampled. If these jugular lymph nodes are found to be positive, a modified radical neck dissection should be added. The morbidity associated with the completion thyroidectomy is minimal. Postoperatively, a 131I scan of the neck should be carried out and ablative doses of radioactive iodine can be given if the uptake in the thyroid bed is greater than 1.5%. Subsequently, all patients are given thyroid suppressive therapy and are monitored closely. This approach will reduce the local recurrence rate and improve the long-term survival.
