Abstract:
Objective To compare the diagnostic value of ultrasound-guided fine needle aspiration cytology (UG-FNAC) combined with BRAFV600E gene mutation and contrast-enhanced ultrasound (CEUS) for thyroid imaging reporting and data system (TI-RADS) type 4 thyroid nodules less than or equal to 1 cm.
Methods From January 2017 to December 2019, 98 patients with 105 TI-RADS type 4 thyroid nodules less than or equal to 1 cm confirmed by surgery and pathological examination in Northern Jiangsu People′s Hospital Affiliated to Yangzhou University were analyzed, UG-FNAC, BRAFV600E and CEUS were performed before surgery. The results were compared with surgical pathology which regarded as the " gold standard" .
Results The diagnostic rates of malignancy (number of malignancy) were 63.81%(67/105), 43.81%(46/105), 55.24%(58/105), 66.67%(70/105), and 53.33%(56/105) for histopathology of surgery, UG-FNAC, UG-FNAC combined with BRAFV600E, CEUS, UG-FNAC and BRAFV600E combined with CEUS, respectively, and all malignant nodules were papillary thyroid microcarcinoma (PTMC). The sensitivities of UG-FNAC, UG-FNAC combined with BRAFV600E, CEUS, UG-FNAC and BRAFV600E combined with CEUS were 67.16%, 83.58%, 86.57%, 83.58%, and the specificities were 97.37%, 94.74%, 68.42%, 100.00%, respectively. The Kappa values of UG-FNAC, UG-FNAC combined with BRAFV600E, CEUS, UG-FNAC and BRAFV600E combined with CEUS were 0.58, 0.75, 0.56, 0.79, and the areas under the curve of receiver operating characteristic (ROC) were 0.823, 0.892, 0.775, 0.918 (all P<0.05), respectively.
Conclusion UG-FNAC and BRAFV600E combined with CEUS has higher accuracy and diagnostic value in the diagnosis of TI-RADS type 4 thyroid nodules less than or equal to 1 cm.
