Abstract

Abstract: This study investigated the diagnostic value of ultrasound-guided thyroid fine-needle aspiration biopsy (US-FNAB) for papillary thyroid microcarcinoma (PTMC). A total of 203 patients (203 nodules) with thyroid micronodules confirmed by pathological examination were selected. All patients underwent US-FNAB examination. The relationship between thyroid micronodules with different cytological characteristics and Bethesda classification of thyroid was analyzed. The pathological examination results were used as the gold standard to analyze the value of US-FNAB in the diagnosis of PTMC. According to the Bethesda classification of thyroid, there were 0 nodules of class Ⅰ, 33 nodules of class Ⅱ, 49 nodules of class Ⅲ, 51 nodules of class Ⅳ, 40 nodules of class Ⅴ, and 30 nodules of class Ⅵ. The proportion of solid nodules, hypoechoic nodules, nodules with blurred borders, and nodule aspect ratio≥1 in malignant thyroid nodules was higher than that in benign nodules (P<0.05); US-FNAB The sensitivity and specificity of differential diagnosis of PTMC and benign thyroid nodules were 85.29% and 91.11%; the sensitivity and specificity of ultrasound in differential diagnosis of PTMC and benign thyroid nodules were 75.00% and 83.70%.The diagnostic value of US-FNAB for PTMC is higher than that of ultrasonography, and it is of great significance for the formulation of clinical individualized treatment plans.
