BISCOLLA, Rosa Paula M.. Cervical lymph nodes metastases in patients with differentiated thyroid cancer. Arq Bras Endocrinol Metab [online]. 2007, vol.51, n.5, pp.813-817. ISSN 1677-9487. http://dx.doi.org/10.1590/S0004-27302007000500019.
Loco-regional recurrences of the differentiated thyroid cancer have been reported to be located in cervical lymph nodes in 60-75% of cases. The widespread use of neck ultrasonography (US) during the follow-up of patients with papillary thyroid carcinoma (PTC) has led to the discovery of small cervical lymph nodes (LN). Although US has a high sensitivity for diagnosing LN, fine needle aspiration biopsy (FNA) and measurement of thyroglobulin in fine needle aspirates (FNA-Tg) have proven to be invaluable tools. The aim of this paper is to review the importance of the early diagnosis of lymph node metastases in the follow-up of patients with differentiated thyroid cancer.
