Diagnostic Performance of Thyroglobulin Value in Indeterminate Range in Fine Needle Aspiration Washout Fluid from Lymph Nodes of Thyroid Cancer
PURPOSE The purpose was to compare the frequency of metastatic and nonmetastatic lymph nodes diagnosed by fine needle aspiration biopsy cytology (FNAC) and thyroglobulin concentration from fine needle aspiration biopsy washout fluid (FNAB-Tg) in an indeterminate range (0.2-100 ng/mL), and to evaluate the most appropriate threshold value of FNAB-Tg in an indeterminate range. MATERIALS AND METH...
متن کاملThyroglobulin measurements in washout of fine needle aspirates in cervical lymph nodes for detection of papillary thyroid cancer metastases.
OBJECTIVE The aim of this study was to evaluate the accuracy of the measurement of thyroglobulin in washout needle aspiration biopsy (FNAB-Tg) to detect papillary thyroid cancer (PTC) metastases. SUBJECTS AND METHODS Forty-three patients (51.4 ± 14.6 years) with PTC diagnosis and evidence of enlarged cervical lymph nodes (LN) were included. An ultrasound-guided fine-needle aspiration of suspi...
متن کاملThe value of thyroglobulin in washout of fine needle aspirate from 16 cervical lesions in patients with thyroid cancer.
BACKGROUND AND OBJECTIVE Thyroglobulin in the needle washout (Tg-FNA) and cytology of fine needle aspiration (cyto-FNA) are recommended for diagnosis of metastatic lymphadenopathies and recurrence of differentiated thyroid cancer. The objective of this study was to assess the value of these procedures in 16 cervical masses from patients with thyroid cancer of the follicular epithelium (TC). P...
متن کاملComparison of LC-MS/MS to immunoassay for measurement of thyroglobulin in fine-needle aspiration samples.
The measurement of thyroglobulin (Tg) by immunoassay (IA) is affected by the presence of anti-Tg autoantibodies (Tg-AAbs), which may cause false-negative or falsely low results (1 ). It has been shown that Tg quantification by LCMS/MS overcomes interference of Tg-AAbs in measurement of Tg (2 ). We previously observed that 20% of Tg-AAb–positive serum samples that tested negative for the presenc...
متن کاملThyroglobulin measurement in fine-needle aspiration biopsy of metastatic lymph nodes after rhTSH stimulation.
BACKGROUND Thyroglobulin measurement in the washout of the needle used in fine-needle aspiration cytology (FNAC) has been proposed for the early detection of lymph node metastasis both in patients with or without serum thyroglobulin antibodies; however, up to now, there have been no reports that recombinant human thyrotropin (rhTSH) stimulation modifies thyroglobulin measurement in lymph node a...
