Abstract
Background. The purpose of this study was to investigate the role of the Bethesda System for Reporting Thyroid Cytopathology (BSRTC) as a prognostic marker in conventional papillary thyroid carcinoma (PTC). Methods. A total of 397 patients who underwent ultrasound-guided fine-needle aspiration biopsy (FNAB) and surgery for conventional PTCs were enrolled. The association between the Bethesda category and histopathologic result was evaluated. Results. Among the Bethesda categories, a significant difference was found in the presence of extrathyroidal extension (Bethesda category III, 3.2% [7 of 220]; category V, 19.1% [42 of 220]; and category VI, 77.7% [171 of 220]; p <.001) and lymph node metastasis (Bethesda category III, 3.8% [6 of 156]; category V, 16.7% [26 of 156]; and category VI, 79.5% [124 of 156]; p <.001). Multivariate analysis showed that the Bethesda category was independently predictive of extrathyroidal extension (p =.013) and lymph node metastasis (p =.035). Conclusion. Conventional PTC with a higher Bethesda category at the time of cytology diagnosis would be poor prognosis. (C) 2016 Wiley Periodicals, Inc.
