Thyroid cancer therapy is based on surgery followed by radioiodine treatment of tumor remnants and metastases. The incorporation of radioiodine by cancer cells is mediated by sodium iodide symporter (NIS), normally present in thyroid follicular cells’ membrane. We studied the expression of NIS in a series of 229 thyroid primary tumors using real time PCR and immunohistochemistry, and searched for possible associations between NIS expression and clinicopathological feature...

Context: Telomerase promoter mutations (TERT) were recently described in follicular cell-derived thyroid carcinomas (FCDTC) and seem to be more prevalent in aggressive cancers.Objectives: We aimed to evaluate the frequency of TERT promoter mutations in thyroid lesions and to investigate the prognostic significance of such mutations in a large cohort of patients with differentiated thyroid carcinomas (DTC).<p class="abstext"...
