Abstract Background Papillary thyroid carcinoma (PTC) is the most common pathological type of thyroid carcinoma. We aim to evaluate the correlation between sonographic features of PTC and cervical lymph node metastasis (CLNM). Methods A total of 1335 patients who underwent thyroidectomy and had pathologically confirmed unifocal PTC were enrolled in the retrospective research. Univariate analysis and logistic analysis were performed to predict CLNM by several independent variables. Receiver operating characteristic (ROC) curve was executed to evaluate the diagnostic performance. Results Univariate analysis showed that location, aspect ratio, margin, echogenic foci, TI-RADS score and grade were related to CLNM (P<0.05). Logistic analysis on sonographic features showed that margin and echogenic foci were independent correlative factors. Meanwhile, logistic analysis included clinical information, ultrasonic measurements and sonographic features showed that gender, age, tumour maximum diameter and volume, cross-sectional aspect ratio, location, margin and echogenic foci were independent correlative factors. The ROC curves were established based on the relevant factors, the AUC of tumour maximum diameter, tumour volume and margin were 0.738, 0.733, and 0.711, respectively. The regression model was constructed with AUC of 0.813, specificity of 70.3%, and sensitivity of 78.5%. ANOVA variance analysis on positive and negative group, tumour maximum diameter, margin, echogenic foci, TI-RADS score and grade had statistical significance (P < 0.05). Conclusion Lower location, larger lesion, margin and echogenic foci were high risk factors for CLNM in PTC, cross-sectional aspect ratio≥1 had more effective predictive value than longitudinal-sectional aspect ratio. Tumor volume was more effective to evaluate the lateral metastasis than maximum tumour diameter, it could guide preoperative FNA for CLNM.

Abstract Background Papillary thyroid carcinoma (PTC) is the most common thyroid carcinoma, which is prone to cervical lymph node metastasis (CLNM). We aim to analyze the correlation between clinical information, ultrasonic (US) measurements of PTC and CLNM. Methods A total of 1335 patients who underwent thyroidectomy and had pathologically confirmed unifocal PTC were enrolled in the retrospective research. Univariate analysis and logistic analysis were performed to predict CLNM in PTC. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic performance. Results Univariate analysis showed that gender, age, tumour maximum diameter and volume, cross-sectional and longitudinal aspect ratio were related to CLNM (P<0.05). Logistic analysis showed that gender, age, tumour maximum diameter and volume were independent correlative factors. The ROC curve was established based on the correlative factors screened by regression analysis. The AUC of the tumour maximum diameter and volume was 0.738 and 0.733, respectively. ANOVA variance analysis on positive and negative group, tumour maximum diameter and volume, cross-sectional and longitudinal aspect ratio had statistical significance (P < 0.05). Conclusion Independent correlative factors for CLNM in patients with unifocal PTC were younger age, male, larger tumour. For tumour with larger volume, central, lateral or both lymph node metastasis should be checked in advance, it would rule as a guidance to perform FNA for CLNM before surgery.

Abstract Background Papillary thyroid carcinoma (PTC) is the most common pathological type of thyroid carcinoma. We aim to evaluate the association of sonographic features of PTC and cervical lymph node metastasis (CLNM) at the initial surgery. Methods Clinical information, ultrasonographic measurements and features for 1335 patients were acquired in data collection. Univariate analysis was performed to test CLNM by 7 independent variables. Receiver operating characteristic (ROC) curve was created to evaluate the diagnostic performance. Results Univariate analysis showed that gland, location, aspect ratio, margin and echogenic foci were independently associated with CLNM metastatic status (P<0.05). Binary linear regression analysis showed that sex, age, tumour maximum diameter and volume, location, margin and echogenic foci were independent correlative factors. The ROC curves were established based on the relevant factors, the AUC of tumour maximum diameter, tumour volume and margin were 0.74, 0.73, and 0.71, respectively. The multiple-variable linear regression model was constructed with AUC of 0.81, specificity of 72.8%, and sensitivity of 75.0%. ANOVA variance analysis for sub-positive groups, tumour maximum diameter, tumour volume, margin and echogenic foci had statistical significance (P<0.05).Conclusion Younger age, male, larger tumour, margin, and echogenic foci were high risk factors for CLNM in PTC. Cross-sectional aspect ratio with value≥1 had higher predictive value for CLNM in patients with larger thyroid tumors.

Abstract Objective Papillary thyroid carcinoma (PTC) is the most common thyroid carcinoma, and is prone to cervical lymph node metastasis (CLNM). We aim to analyze the correlation between clinical information, ultrasonic parameters of PTC and CLNM. Methods 1335 patients who had pathologically confirmed unifocal PTC were enrolled. Univariate and multivariate logistic analysis were performed to predict CLNM in PTC patients. The receiver operating characteristic (ROC) curve was used to evaluate the diagnostic performance. Results Univariate analysis showed that gender, age, maximum tumor diameter and volume, cross-sectional and longitudinal aspect ratio were related to CLNM (P < 0.05). Multivariate logistic analysis showed that gender, age, maximum tumor diameter and volume were independent correlative factors, cross-sectional aspect ratio had significant difference for PTC patients excluding PTMC to predict CLNM. The area under the curve (AUC) of the maximum tumor diameter and volume was 0.738 and 0.733, respectively. Maximum tumor diameter and volume, and cross-sectional and longitudinal aspect ratio were statistically significant following analysis of variance (P < 0.05). Conclusions Younger age, male, and larger tumor were high risk factors for CLNM in patients with unifocal PTC. Cross-sectional aspect ratio had a more effective predictive value for CLNM in patients with larger thyroid tumors.

Node Metastasis

Cervical lymph node metastasis is common in patients with papillary thyroid carcinoma (PTC).Salmonellaspecies are rarely reported as causative agents in focal infections of the head and neck. The cooccurrence of lymph node metastasis from PTC and a bacterial infection is rare. This report describes a 76-year-old woman with a cervical lymph node metastasis from PTC andSalmonellainfection of the same lymph node. The patient presented with painful swelling in her left lateral neck region for 15 days, and neck ultrasonography and computed tomography showed a cystic mass along left levels II–IV. The cystic mass was suspected of being a metastatic lymph node; modified radical neck dissection was performed. Histopathological examination confirmed the presence of PTC in the resected node and laboratory examination of the combined abscess cavity confirmed the presence ofSalmonella Typhi. Following antibiotic sensitivity testing of the culturedSalmonella Typhi, she was treated with proper antibiotics. Cystic lesions in lymph nodes with metastatic cancer may indicate the presence of cooccurring bacterial infection. Thus, culturing of specimen can be option to make accurate diagnosis and to provide proper postoperative management.
