Abstract

Objective: The value of fine needle aspiration under ultrasound guidance is for solitary solid thyroid nodules from 10 to 20 mm. Research subjects and methods: The study was conducted on patients who came for examination and treatment at K Tan Trieu hospital from August 2018 to June 2019 with 158 patients. Results: Patients with TIRADS 5 of 122 accounted for 77.2%, TIRADS 4 of 36 accounted for 22.8%; Among 128 FNAUS thyroid nodules with malignant cells, 118 thyroid nodules were cancerous, accounting for 92.2%, the remaining 10 thyroid nodules were benign, accounting for 7.8%; Of the 30 FNAUS thyroid nodules with benign cells, 16 thyroid nodules were cancerous, accounting for 53.3%, the remaining 14 thyroid nodules were benign, accounting for 46.7%; FNAUS values ​​in the group of patients with TIRADS 4-5 thyroid nodules in cancer diagnosis are as follows with sensitivity Se = 88.1%, specificity Sp = 58.3%, positive predictive value PPV = 92 ,2%, negative predictive value NPV = 46.7%; Acc accuracy = 82.54%. Conclusion: The value of FNAUS in research is quite high, the correct diagnosis rate is up to 82.54% in diagnosing malignant thyroid nodules; sensitivity 88.1%; Specificity 58.3%
