Abstract
Background
Epidemiologic studies demonstrated higher incidence of thyroid cancer in patients with multinodular goiters compared to the general population. The aim of this study was to evaluate the risk of finding significant thyroid cancer in patients undergoing thyroidectomy for presumed benign disease.
Methods
The records of 273 patients operated for indications other than cancer or indeterminate cytology were reviewed and analyzed.
Results
202 (74 %) patients had a preoperative fine-needle aspiration (FNA) performed. FNA was benign in 96 % of patients and non-diagnostic in 4 %. Malignancy was unexpectedly found in 50 (19 %) patients. Papillary carcinoma constituted 94 % of cancers and 86 % of cancers were incidental microcarcinomas. Only 7 (2.6 %) patients of the entire cohort had tumors greater than 1 cm, of those only 3 had a previous benign FNA (false-negative rate 1.5 %).
Conclusions
The rate of significant thyroid cancer found unexpectedly in resected goiters is extremely low. A negative FNA excludes significant cancer with near certainty.
