Sonographic Characteristics of Papillary Thyroid Carcinoma With Coexistent Hashimoto’s Thyroiditis in the Preoperative Prediction of Central Lymph Node Metastasis

Abstract: The purpose of this study was to evaluate the usefulness of the sonographic characteristics of papillary thyroid carcinoma (PTC) with Hashimoto’s thyroiditis (HT) for predicting central lymph node metastasis (CLNM). One hundred thirty-three patients who underwent thyroidectomy and central cervical lymph node dissection for PTC with coexistent HT were retrospectively analyzed. All PTCs with HT were preoperatively evaluated by ultrasound (US) regarding their nodular number, size, component, shape, margin, echoge… Show more

“…However, mixed cystic nodules or almost cystic nodules (cystic portion >75%) were excluded from previous studies due to the demand for elastography ( 10 , 17 , 18 ). In our study, 43.5% of PCPTCs showed hypoenhancement, 95.7% of PCPTCs showed heterogeneous enhancement, and 87% of PCPTCs exhibited centrifugal perfusion, which is inconsistent with the CEUS enhancement of solid PTCs reported in previous studies ( 10 , 19 , 20 ). Compared with benign nodular goiters, PCPTCs more frequently had hypoenhancement, heterogeneous enhancement, centrifugal perfusion, PI index <1, TP index ≥1, and AUC index <1 on preoperative CEUS.…”

“…Thus, univariate and multivariate analyses were performed to discover more indicators in predicting the CLNM. In accordance with the previous findings (16,24,27), male gender, tumor size (>1 cm), and micro-calcification of the tumor were the risk factors of CLNM during the univariate analysis. Among the PTC patients with HT, the serum TgAb level was significantly higher in the CLNM group (656.95 ± 931.09 vs. 363.49 ± 440.51, p = 0.002) and the serum TPOAb level was lower in the CLNM group (137.70 ± 142.11 vs. 195.26 ± 195.13, p = 0.016).…”

“…As a result, how surgeons could preoperatively distinguish the hyperplastic and malignant lymph nodes becomes a pivotal step in guiding the precision surgical protocol in dealing with the CLN. Reviewing recent studies on evaluating the prediction risk factors of CLNM in PTC patients (22)(23)(24), only a few studies were focusing on the PTC patients with the presence of HT condition (11,12,(16)(17)(18). Moreover, a majority of prediction variables were only dependent on the single examination result, like the thyroid function test (18), sonographic characteristics (16), or clinical factors (17).…”
