The Application Value of Ultrasound Guided Thyroid Fine Needle Puncture US-FNAC Diagnosis in Thyroid Cancer
Objective:To explore the application value of ultrasound-guided thyroid fine needle aspiration cytology(US-FNAC)in thyroid adenocarcinoma.Methods:80 cases(95 nodules)of thyroid nodules admitted from September 2020 to September 2023 were selected for retrospective analysis.All the general clinical data,ultrasound diagnosis data,US-FNAC examination data and postoperative pathological data were complete.The postoperative pathological histological results were taken as the"gold standard",and the diagnostic results of surgical pathology and US-FAC in 80 patients,and the diagnosis of thyroid cancer by US-FNAC was analyzed.Subsequently,11 patients with inaccurate US-FNAC diagnosis were included in the inaccurate group,and the remaining patients were included in the accurate group to analyze the diagnostic accuracy of US-FNAC.Results:The surgical pathological examination results showed that among the 95 nodules,41 were benign and 54 were malignant,including 48 papillary thyroid carcinoma and 6 follicular thyroid carcinoma.US-FNAC examined 52 of the 95 nodules as benign,43 malignant,no difference between US-FNAC(P>0.05).A total of 70 of the 80 patients had consistent pathological results after US-FNAC,10 cases of inconsistency.The area under the curve of US-FNAC for thyroid cancer diagnosis was 0.832,the specificity was 91.47%,a sensitivity of 73.59%,the area under the curve for the pathological diagnosis was 0.891,the specificity was 98.52%,sensitivity was 90.26%.The nodule location,nodule composition,nodule diameter,and blood supply varied significantly between the accurate and inaccurate groups(P<0.05).Conclusion:US-FNAC had a higher diagnostic accuracy for thyroid cancer,especially for thyroid nodules with non cystic components,nodule diameter≥2cm,and lack of blood supply.However,there were still some misdiagnosis and missed diagnosis cases.
