169 patients of papable thyroid nodules were clinically assessed with preoperative fine niddle aspiration(FNA) and postoperative histopathology from January, 1990 to October, 1991 at the Department of Surgery of Inha University College of
Medicine.
@ES The results were obtained as follows:
@EN 1) Diagnostic cells were aspirated from thyroid nodules in 154 of 169 patients.(cell obtainability, 91%)
2) Thyroid nodules were prevalent in 4th, 5th and 6th decade and the peak age incidence was in the 4th decade(40.5%). Sex ratio(M:F) was 1:9.
3) In cytologic classification, 125 cases(64%) were benign thyroid nodules, 20 cases(12%) were malignant thyroid nodule, 8 cases were thyroiditis( 1 cases was Hashimoto's thyroiditis).
4) In pathologic classification, benign versus malignant nodules ratio were 2.7:1, among the malignant nodules(19 cases), 17 cases were papillary ca(5 cases were papillary microcarcinoma) and 2 cases were follicular ca.
5) Diagnostic accuracy of FNA on 51 cases with thyroid nodules was 81.6%, sensitivity 86%(12 of 14), speciticity 96.9%(31 of 32), false positive 7.7%(1 of 3) and false negative 18.9%(7 of 38).
6) Benign thyroid nodules were combined with papillary microcacinoma(4 cases), benign follicular neoplasm had 3 cases of papillary microcarcinoma and nodular hyperplasia had 1 case of papillary microcarcinoma. Therefore, we should be suggest
surgical
treatment of benign thyroid nodules.
7) No compication was found in this study.
8) We had gained the results within 24 hours.
