Predictive Factors of Lymph Node Metastasis in Patients With Papillary Microcarcinoma of the Thyroid

Predictive Factors of Lymph Node Metastasis in Patients With Papillary Microcarcinoma of the Thyroid

Papillary thyroid microcarcinoma (PTMC), defined as a tumor with larger diameter ≤ 1 cm, is considered a tumor with an indolent course and an excellent prognosis. Nevertheless, the incidence of lymph node metastasis in PTMC is not negligible, reaching up to 65% in some series. The aim of this study was to assess the incidence of lymph node metastasis in patients with PTMC and to evaluate predictive factors for lymph node metastasis.

Inclusion Criteria:

Patients with papillary microcarcinoma of the thyroid

Exclusion Criteria:

Patients with thyroid nodules > 1 cm; incomplete data
