Tumor aggressiveness risk factors in the differentiated thyroid carcinoma.

Background: The differentiated thyroid carcinoma (DTC) is the most frequent malignancy in endocrinology (95%). Our aim was to retrospectively compare risk factors of tumor aggressiveness and history of thyroid disease in patients with conventional DTC and differentiated thyroid microcarcinoma (DTMC).

Methods: Retrospective analysis of 167 patients after total thyroidectomy with a histologically confirmed DTC, of which 83 patients with conventional DTC (> 1 cm) and 84 with DTMC (≤ 1 cm).
