MAC DERMOTT, Mariela Margarita; GAUNA, Alicia  e  E.W. DE YAMPEY, Judith. Impact of lymph node involvement on prognosis and outcome of papillary thyroid carcinoma. Rev. argent. endocrinol. metab. [online]. 2017, vol.54, n.2, pp.51-63. ISSN 1851-3034.

Cervical lymph node metastases are usually present in a high number of cases with papillary thyroid carcinoma. However, many studies have shown that not all lymph node metastases have the same impact on the outcome of this disease. Argentina, Chile, and Brazil have recently changed their differentiated thyroid carcinoma (DTC) guidelines and recommend a different ranking of risk and therapeutic approach according to the number, size, and extension of lymph node metastasis. An analysis of lymph node metastases is presented in this article, which includes their characteristics and impact on DTC. As this analysis was made before the latest publication of the new American Thyroid Association guidelines, some aspects of these guidelines have also been included.
