Objective:To explore the clinical value of ultrasound-guided fine-needle aspiration biopsy in the diagnosis of thyroid cancer and assessment of cervical lymph node metastasis.Methods:The clinical data of 90 patients with thyroid cancer who received treatment in Zhoushan Hospital from October 2018 to April 2021 were retrospectively analyzed. All patients underwent a two-dimensional ultrasound examination and ultrasound-guided fine-needle aspiration biopsy before surgery. Taking surgical and pathological diagnosis as the gold standard, the efficiency of two-dimensional ultrasound examination versus ultrasound-guided fine-needle aspiration biopsy in the diagnosis of thyroid cancer and cervical lymph node metastasis and in the identification of benign and maligant lymph nodes were investigated. Multivariate Logistic regression analysis was performed to analyze the correlation between different ultrasound signs and the detection rate of lymph nodes. Results:Pathological results showed that among the 90 patients, 73 patients had thyroid cancer, and 17 patients had benign lesions. Ultrasound-guided fine-needle aspiration biopsy results showed that 70 patients had thyroid cancer, and 20 patients had benign lesions, including 4 cases of missed diagnosis and 2 cases of misdiagnosis. The diagnostic sensitivity, specificity, accuracy rate, and Kappa value were 94.52%, 88.24%, 93.33%, and 0.79, respectively. These were highly consistent with the surgical and pathological diagnosis (Kappa value > 0.75). Two-dimensional ultrasound revealed 69 patients with thyroid cancer and 21 patients with benign lesions, including 7 cases of missed diagnosis and 4 cases of misdiagnosis. The diagnostic sensitivity, specificity, accuracy rate, and Kappa value were 90.41%, 76.47%, 87.78%, and 0.63, respectively. Pathological results revealed that cervical lymph node metastasis occurred in 12 patients, and it did not occur in 78 patients. The diagnostic sensitivity, specificity, accuracy rate, and Kappa value of ultrasound-guided fine-needle aspiration biopsy were 83.33%, 97.50%, 95.65%, and 0.81 respectively. These were highly consistent with surgical and pathological results (Kappa value > 0.75). The diagnostic sensitivity, specificity, accuracy rate, and Kappa value of two-dimensional ultrasound examination were 75.00%, 94.87%, 92.22%, and 0.67, respectively. A total of 156 lymph nodes were detected by ultrasound-guided fine-needle aspiration biopsy, including 103 benign lymph nodes and 53 malignant lymph nodes, with a diagnostic accuracy rate of 94.17% and 96.22%, respectively. A total of 173 lymph nodes were detected by two-dimensional ultrasound, including 111 benign lymph nodes and 62 malignant lymph nodes, with a diagnostic accuracy rate of 91.89% and 91.93%, respectively. There were no significant differences in the diagnostic accuracy of benign and malignant lymph nodes between the two examination methods ( χ2 = 0.42, 0.92, both P > 0.05). Multivariate logistic regression analysis showed that hyperechoic masses, cystic lesions, and internal calcification were significantly correlated with the detection rate of lymph nodes diagnosed by two-dimensional ultrasound and ultrasound-guided fine-needle aspiration biopsy ( OR = 6.64, 5.32, 4.12, 7.07, 5.60, 5.06, all P < 0.05). Conclusion:Ultrasound-guided fine-needle aspiration biopsy has high diagnostic efficiency for thyroid cancer and cervical lymph node metastasis. Ultrasound signs of hyperechoic mass, cystic lesions, and internal calcification are significantly correlated with the detection rate of lymph nodes.
