Abstract:
Objective To evaluate whether ultrasonographic features of thyroid nodules are associated with histological malignancy, and to set up helpful criteria in identifying those who should accept subsequent fine-needle aspiration biopsy (FNAB). Methods 146 thyroid nodules of 123 patients accepted ultrasonographic evaluation and FNAB. All patients but one with suspicious or malignant cytology were operated. Results Out of total 146 nodules, 43 were histologically malignant, 102 were cytologically benign, and 1 nodule with suspicious cytology was not followed. Hypoechoic pattern, blurred margins, irregular shape, microcalcification, and type Ⅲ vascularity were significantly more frequent in malignant than benign nodules (P ＜ 0. 05). No one of the ultrasonographic features could independently predict malignant nodules. A better compromise is probably to apply FNAB in nodules with at least one or two malignant ultrasonographic signs. Conclusion No single parameter could satisfactorily identify a subset of patients to be selectively examined by FNAB. A cost-effective approach to FNAB should depend on combination of specific ultrasonographic features.
