Necessity and safety of completion thyroidectomy for differentiated thyroid carcinoma.

Abstract

Although the significance and treatment of papillary carcinoma are debated on the basis of size and grade of the primary lesion and age and sex of the patients, once the diagnosis is made in one lobe we believe that a completion thyroidectomy should be considered, not only for papillary carcinomas but also for follicular carcinomas because 47% (papillary) to 33% (follicular) of these patients will harbor the neoplasm in the contralateral lobe.
