Solitary thyroid nodules

Abstract

A study was made of 67 patients with solitary thyroid nodules in which strict criteria to eliminate the probability of cancer, including a history of radiation to the neck, were used. Twelve (17.9%) were found to have histologic malignancy. This figure is threefold that of a study made by one of the authors 11 years earlier, but comparable to others more recently reported from cancer centers elsewhere. It is not certain whether the apparent increase is actual or merely the result of more careful screening of patients for referral. Shrinking of the nodule by thyroid suppression therapy had been definite but incomplete in three nodules, one of which was found to be malignant. Excision is recommended for all persistent thyroid nodules.
