RESUMO
Recorrências regionais dos carcinomas diferenciados de tiróide (CDT) são representadas por linfonodos cervicais em 60-75 por cento dos casos. Com a introdução da ultra-sonografia cervical (USC) no seguimento dos pacientes com carcinoma papilífero de tiróide (CPT) tornou-se freqüente o encontro de pequenos linfonodos (LNs) cervicais. Porém, apesar da USC apresentar alta sensibilidade, o estudo citológico obtido por punção aspirativa (PAAF), e nos últimos anos, a dosagem da tiroglobulina (Tg) no lavado da agulha da PAAF (Tg-PAAF), vêm assumindo papel importante no diagnóstico de LNs cervicais. O objetivo deste estudo é revisar a importância do diagnóstico precoce das metástases em linfonodos cervicais no seguimento dos pacientes com carcinoma de tiróide.
ABSTRACT
Loco-regional recurrences of the differentiated thyroid cancer have been reported to be located in cervical lymph nodes in 60-75 percent 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.
