The aim of this study was the assessment of diagnostic utility of fine-needle aspiration biopsy needle washout fluids (FNAB-Tg) in the cases of thyroid carcinoma recurrence and analysis of false-positive and false-negative results.Methods: Two hundred and fifteen FNAB-Tg samples from 201 patients with a history of differentiated thyroid carcinoma with suspicious lymph nodes were included in analysis. The wash-out of needle rinsed with 0.5ml of normal sal...

Introduction: Approximately 5–20% patients treated for differentiated thyroid carcinoma (DTC) develop metastases to the neck lymph nodes. Ultrasound-guided fine-needle aspiration biopsy (FNAB) is a routinely used method in the examination of suspicious lymph nodes. The measurement of thyroglobulin (Tg) levels in needle washout fluids (FNAB-Tg) has been reported to increase the diagnostic accuracy of FNAB.Description of methods/designs: A total of 10...
