MAIA, Ana Luiza et al. Thyroid nodules and differentiated thyroid cancer: Brazilian consensus. Arq Bras Endocrinol Metab [online]. 2007, vol.51, n.5, pp. 867-893. ISSN 1677-9487. http://dx.doi.org/10.1590/S0004-27302007000500027.
Thyroid nodules are a common manifestation of thyroid diseases. It is estimated that ~10% of adults have palpable thyroid nodules with the frequency increasing throughout life. The major concern on nodule evaluation is the risk of malignancy (5-10%). Differentiated thyroid carcinoma accounts for 90% of all thyroid malignant neoplasias. Although most patients with cancer have a favorable outcome, some individuals present an aggressive form of the disease and poor prognostic despite recent advances in diagnosis and treatment. Here, a set of clinical guidelines for the evaluation and management of patients with thyroid nodules or differentiated thyroid cancer was developed through consensus by 8 member of the Department of Thyroid, Sociedade Brasileira de Endocrinologia e Metabologia. The participants are from different reference medical centers within Brazil, to reflect different practice patterns. Each committee participant was initially assigned to write a section of the document and to submit it to the chairperson, who revised and assembled the sections into a complete draft document, which was then circulated among all committee members for further revision. All committee members further revised and refined the document. The guidelines were developed based on the expert opinion of the committee participants, as well as on previously published information.
