Abstract |
Background and Objectives: Thyroid nodules can be diagnosed by FNAB, neck sonography, CT scan, or frozen section with relative accuracy. But some cases, which show no malignancy with those methods, are proved differentiated carcinomas on permanent sections. These false negative results of those diagnostic methods pose difficulties in the surgeon's decision-making process. We analyzed completion thyroidectomies retrospectively in order to make a treatment guideline for thyroid nodules.
Materials and Methods: During the last six years, we performed 243 thyroid lobectomies, no evidence of malignancy with preoperative or intraoperative diagnostic methods at the Department of Otolaryngology-Head and Neck Surgery, Ansan and Anam Korea University Hospital. Among these cases, 23 patients (male 6, female 17, mean age 33.4 year old) were proved differentiated thyroid carcinomas on permanent section and we performed completion thyroidectomies.
Results Preoperative FNAB showed seven cases of nodular hyperplasia, 11 cases of follicular adenoma, and five cases of inadequate specimen. Among total 15 cases on frozen section, five cases were nodular hyperplasias, and 10 cases were follicular adenomas. Pathologic results of the permanent section were six cases of papillary cell carcinoma and 17 cases of follicular cell carcinoma. Completion thyroidectomy was performed on all these cases.
Conclusion FNAB and frozen section cannot be sufficient to make the diagnosis of thyroid nodule, we consider that completion thyroidectomy should be performed at the moment with malignant evidence on permanent section. |
